Congressional Moves To Gut OSTP

Key legislator disses White House science office, Science

"The White House science office hasn't been very productive under President Barack Obama, says the chairman of a key congressional research spending panel. And Representative John Culberson (R-TX) says he'd like to see it downsized. ... Since becoming CJS chairman in January 2015, Culberson has used his position as a "cardinal" to advocate for his scientific priorities, starting with a multi-billion-dollar NASA mission to a jovian moon that some scientists believe may harbor life."

Keith's note: Funny how a member of Congress with zero science training shoves Europa missions down NASA's throat and then complains about a congressionally-mandated position in the Executive Branch that overtly seeks to have actual scientific input - from actual scientists - so as to make informed decisions - about science.

Milky Way over Shipwreck


What happened to this ship? It was carried aground by a giant storm that struck the coast of Argentina in 2002. The pictured abandoned boat, dubbed Naufragio del Chubasco, wrecked near the nearly abandoned town of Cabo Raso (population: 1). The rusting ship provides a picturesque but perhaps creepy foreground for the beautiful sky above. This sky is crowned by the grand arch of our Milky Way and features galaxies including the Large and Small Magellanic Clouds, stars including Canopus and Altair, planets including Mars and Neptune, and nebulas including the Lagoon, Carina, and the Coal Sack. The mosaic was composed from over 80 images taken in early September. A 360-degree interactive panoramic version of this image is also available. The adventurous astrophotographer reports that the creepiest part of taking this picture was not the abandoned ship, but the unusual prevalence of black and hairy caterpillars. via NASA http://ift.tt/2gJKk0t

Get Used To Having Less Money For NASA

Trump's First 100 Days: Space, Scientific American

"What is certain, [Bob] Walker says, is that Trump's "space policy doesn't contemplate any real increases in NASA's spending.", It will likely have to accomplish all that it is being asked to do now and in the future without significant boosts to its bottom line, and with the distinct possibility of deep budget cuts. And that, more than anything else, could be very bad news for the space agency and its programs."

Another Jumping Sun Dog

ISS Daily Summary Report – 11/29/2016

Robotic External Leak Locator (RELL) Operations: On GMT 333, upon powering up the Space Station Remote Manipulator System (SSRMS) Special Purpose Dexterous Manipulator (SPDM) for RELL ops, the Dexterous Manipulator Control Software (DMCS) Payload Status showed “Unloaded” for ORU Tool Changeout Mechanism (OTCM) 2 instead of “Secure” which was unexpected since it was captured to Robotic Micro Conical Tool (RMCT) 2. Root cause was traced to software changes made with the “Mount Logan” software patch. Ground teams agreed to completely rolling back the original software MSS 8.3 software version (pre-Mt Logan). Overnight the team successfully re-installed a pre-Mt. Logan version of MSS software, and reinitialized the SPDM. OTCM2 is now showing “secure” (versus the earlier improper “unloaded” signature). This allowed ground controllers to perform the RELL operations that were originally planned yesterday. The Japanese Experiment Module (JEM) Airlock (JEMAL) slide table with the RELL package was extended. Ground Controllers then grasped the RELL with the SPDM and began the checkout by pointing RELL towards deep space in order to scan a clean environment as a baseline, and data is being collected. Tomorrow will begin the planned surveys. RELL is an instrumentation package that is maneuvered externally by the SSRMS/SPDM to detect local pressure variations to help in locating a leak. For this demonstration, a predetermined scan/survey procedure will be executed that characterized the ISS environment and scans various ISS elements containing ammonia lines and systems. Planned operations later this week will also attempt to identify the source of the “white flakes” that have been noticed on downlink video.  Marangoni Ultrasonic Velocity Profiler-2 (UVP2) Installation: The crew began the installation activities for the next Marangoni experiment in the Fluid Physics Experiment Facility (FPEF) within the Japanese Experiment Module’s (JEM’s) Ryutai Rack. The crew cleaned the FPEF Infrared (IR) Imager forward and downward mirrors, then installed the Marangoni-UVP-2 cassette. The crew then connected cables and performed leak checks. Spatio-temporal Flow Structure in Marangoni Convection (Marangoni-UVP) investigates the fundamental physics of surface tension where liquid and gas meet. Specifically, it investigates a phenomenon known as Marangoni convection, a type of flow that is driven by temperature differences at the liquid and gas interface. The FPEF enables observations of liquid and gas flow in three dimensions, and the microgravity environment on the ISS provides an ideal setting to study convection. Improved understanding of liquid flow physics could lead to more efficient industrial processes, semiconductors, optical materials and biological materials for use in space and on Earth. Sarcolab-3: After successfully configuring the Muscle Atrophy Research & Exercise System (MARES) in the Columbus module yesterday, today the crew will begin the three day operations phase of joint-NASA-ESA-Russia Sarcolab experiment. Today the subject ingressed MARES, followed by the operator performing ultrasound measurements of the right calf muscle, with remote guidance and direction assistance from ground specialists.  The subject then donned Percutaneus Electrical Muscle Stimulator (PEMS), for electrical stimulation at rest and during voluntary muscle contraction, and Electromyography (EMG) electrodes to measure calf muscle and tendon response at the ankle (calf muscle insertion). The MARES equipment and software is used to measure calf strength during spaceflight; the inflight data will then be compared to preflight and postflight measurements to measure the impact of a hypothesized microgravity induced muscle loss. The goal of the Myotendinous and Neuromuscular Adaptation to Long-term Spaceflight (Sarcolab) investigation is to advance the understanding of muscle function and atrophy in space. Results will contribute to further improvement of countermeasures for long duration spaceflight. Aerosol Sampler Deployment: The crew will deploy seven passive and two active Aerosol Samplers in various locations around the ISS. Aerosols are small particles suspended in the air, and in Earth’s atmosphere, aerosols include soot, dust, pollen and a wide range of other natural and human-made materials. But smoke does not rise and dust does not settle in microgravity the way they do on Earth, causing aerosols to behave differently and pose hazards for crew members breathing the air. The Aerosol Sampling Experiment (Aerosol Sampler) collects airborne particles in the International Space Station’s (ISS) cabin air, and returns them to Earth so scientists can study the particles with powerful microscopes. For this experiment, particles collected on the cabin air samples are analyzed using a variety of microscopic techniques including: light microscopy, Raman spectroscopy, scanning electron microscopy, computer controlled scanning electron microscopy, and scanning transmission electron microscopy.

More Inbred Thinking Amongst Space Advocates

Keith's note: Explore Mars had a "leadership dinner" in Washington, DC tonight. This is a group photo (larger image) posted on Facebook. Here we go again. Another space group has a meeting. Guess who shows up: One female, nine males (mostly older white guys). This is not remotely representative of who will - should - explore Mars. The folks at Explore Mars mean well. But this event is representative of a much more pervasive issue in the space advocate community - lack of diversity. Until the usual suspects in the space advocate leadership clique get the message that they need to be far more representative of the taxpayers/citizenry who will pay for their party their impact will be minimal - at best. More choir practice in an echo chamber.

Keith's update: I am told by a participant in this event that this was a "[this was a] random group based on availability. [The] president of the organization is a woman and two of the Board of Advisers are women (and another one pending), none of whom were present." That said, the gender and age imbalance is still unrepresentative of the real world and will continue to be so - until the space crowd gets the message that they need to reflect the reality of the world around them - not the one they imagine inside their heads.

Upcoming Action On A New NASA Authorization Act

Senate Floor Action on New NASA Authorization Act Could be Imminent, Space Policy Online

"Senate and House negotiators reportedly are close to agreement on a final version of a FY2017 NASA authorization act. Senate floor action on a draft compromise bill could come as early as tomorrow. A draft of a revised version of the bill reportedly reflecting compromise with the House is now circulating and rumors are that the Senate may take it up as early as tomorrow. SpacePolicyOnline.com obtained a copy of the new draft. A quick glance suggests that it is similar to what cleared the Senate committee, while incorporating elements of H.R, 810 and H.R. 2039 plus new provisions. These are a few highlights of the 114-page draft."

"As the incoming Administration evaluates ARM, it would benefit from clear guidance from both NASA and its advisory bodies. Similarly, it should be unencumbered by decisions made in the twilight of this Administration's term. Contrary to the assertions made in the press release, numerous advisory bodies have questioned the merits of the President's ARM mission. The NASA Advisory Council, the Small Bodies Assessment Group (SBAG), and the National Research Council have all raised concerns with the mission since its proposal by the Administration," the letter states."

President-Elect Trump Announces Additional Agency Landing Team Members

"National Aeronautics and Space Administration
Christopher Shank
Employer (current or most recent): U.S. House Committee on Science, Space, and Technology (Retired)
Funding source: Volunteer"

Keith's note: Chris Shank is currently policy director for the Science, Space, and Technology Committee. Prior to that he worked at NASA as part of Mike Griffin's so-called "Band of Brothers" as Director of Strategic Investments and Chief of Strategic Communications. It would not necessarily be incorrect to look at what the House Science Committee has been doing over the past few years (Pro-Constellation, Pro-SLS, Anti-ARM, preference for going back to the Moon, Earth science skepticism, subpoenas to NOAA and EPA over climate and environmental issues) to get an understanding of Shank's possible stance on space issues. That said, Chris certainly understands space.

Also, Mark Albrecht, once thought by many to be part of NASA's transition team, is listed as one of the Department of Defense Landing Team members.

ISS Daily Summary Report – 11/28/2016

Device for the study of Critical Liquids and Crystallization High Temperature Insert-Reflight (DECLIC-HTI-R) Installation: Today the crew installed and connected the Electronics Locker and Experiment locker cables for the DECLIC facility, before installing the HTI-R experiment insert. During operations, 400 milliliters of water leaked during the quick disconnect connection, but connecting the cables in reverse order proved to resolve the problem and the DECLIC-HTI-R was activated successfully. There was no JEM impact to the water leak. DECLIC is an apparatus developed by CNES for a NASA Express rack to support the study of material growth and the behavior of liquids near their critical point. It provides all subsystems required to operate an experiment dedicated insert installed on an optical bench. HTI is one of the modules that have been developed for DECLIC. The science of HTI is based on the analysis of optical and thermal properties of H20 near the critical points. HTI is intended to enable the study of near-critical water, and later of other super-critical fluids. It is installed on orbit in the Experiment Locker of the DECLIC instrument. It provides the environment and stimuli (quench, temperature gradient, heat pulse, optical observations) for the cell containing the sample under study. The mechanical part accommodating the fluid cell is called SCU (Sample Cell Unit).  Marangoni Deformation 30 Surf Removal: Following the successful run of Dynamic Surf/Marangoni Deformation, today the crew removed the Marangoni experiment from the Fluid Physics Experiment Facility (FPEF) within the Ryutai Rack. The Dynamic Surf investigation is part of a series of JAXA experiments that Marangoni convection driven by the presence of surface tension gradient as produced by a temperature difference at a liquid/gas interface. Fluid convection observations of a silicone oil liquid bridge that is generated by heating the one disc higher than the other within the Fluid Physics Experiment Facility (FPEF). By observing and understanding how such fluids move researchers can learn about how heat is transferred in microgravity, and ultimately drive the design and development of more efficient fluid flow based systems and devices. Sarcolab-3: Today the crew completed the setup phase of the joint-NASA-ESA-Russia Sarcolab experiment, by deploying and configuring the Muscle Atrophy Research & Exercise System (MARES) in the Columbus module. Tomorrow’s activities will be the beginning of the three day operations phase of the experiment. Myotendinous and Neuromuscular Adaptation to Long-term Spaceflight (Sarcolab) investigates the adaptation and deterioration of the soleus, or calf muscle, where it joins the Achilles tendon, which links it to the heel and carries loads from the entire body. Muscle fiber samples are taken from crew members before and after flight, and analyzed for changes in structural and chemical properties. MRI and ultrasound tests and electrode stimulation are conducted to help assess muscle and tendon changes caused by microgravity exposure.  Human Research Program (HRP) Collections: This morning, a crewmember conducted the first run of Biochemistry Profile and Repository and the second session of Marrow urine collections.  The shared samples were placed in Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) for storage and return on a future flight. The Biochemical Profile experiment tests blood and urine samples obtained from astronauts before, during, and after spaceflight. Specific proteins and chemicals in the samples are used as biomarkers, or indicators of health. Post-flight analysis yields a database of samples and test results, which scientists can use to study the effects of spaceflight on the body. Repository is a storage bank used to maintain biological specimens over extended periods of time and under well-controlled conditions. This repository supports scientific discovery that contributes to our fundamental knowledge in the area of human physiological changes and adaptation to a microgravity environment and provides unique opportunities to study longitudinal changes in human physiology spanning many missions. Robotic External Leak Locator (RELL) Operations:  In preparation for RELL operations the Space Station Remote Manipulator System (SSRMS) Special Purpose Dexterous Manipulator (SPDM) Arm #2 ORU Tool Changeout Mechanism (OTCM) was powered up while grasped to Robot Micro Conical Tool (RMCT) 2.  After power up, the payload status came up in an unexpected configuration as reported in telemetry.  The OTCM showed captured and the Payload status showed Unloaded.  Since SPDM Arm 2 was holding RMCT 2 the Payload Status should have shown Secured.  Today’s operations were performed using a new software version.  The ground teams performed some non-evasive troubleshooting in attempt correct the issue with no success.  The teams agreed to stand down and retract the RELL back into the JEM Airlock (JEMAL). RELL will remain in the JEMAL until teams determine the go forward plan. Today’s Planned Activities All activities were completed unless otherwise noted.

Arp 240: A Bridge between Spiral Galaxies from Hubble


Why is there a bridge between these two spiral galaxies? Made of gas and stars, the bridge provides strong evidence that these two immense star systems have passed close to each other and experienced violent tides induced by mutual gravity. Known together as Arp 240 but individually as NGC 5257 and NGC 5258, computer modelling and the ages of star clusters indicate that the two galaxies completed a first passage near each other only about 250 million years ago. Gravitational tides not only pulled away matter, they compress gas and so caused star formation in both galaxies and the unusual bridge. Galactic mergers are thought to be common, with Arp 240 representing a snapshot of a brief stage in this inevitable process. The Arp 240 pair are about 300 million light-years distant and can be seen with a small telescope toward the constellation of Virgo. Repeated close passages should ultimately result in a merger and with the emergence of a single combined galaxy. via NASA http://ift.tt/2gyc9wh

Transition Teams and Draining Swamps

A transition vet offers tips to Trump's NASA transition team, Courtney Stadd, SpaceNews

"You will also be subject to many rumors. Information is power in D.C. Any tidbit of information, no matter how trivial, is worth something to the consultants, lobbyists, journalists, bloggers, and self-appointed social media space policy mavens who are constantly trying to demonstrate their inside knowledge. And many people with an interest in the issues within your portfolio are not beyond greatly exaggerating their level of access. I've lived and worked in the nation's capital for 40 years and can attest to the hypocrisy that has always been a growth industry within the Beltway. But I have to say that in the wake of this election, I have never seen anything like the hypocrisy among the political class. The very people who disdained Donald Trump on the Monday before the election were currying for political favor within 24 hours of Hillary Clinton's concession phone call. By now, I am sure you have discovered many "friends" you never knew existed the day before the election."

Is Trump Going To Gut NASA Earth Science? Who Knows.

Trump's space policy reaches for Mars and the star, Space News

"NASA should be focused primarily on deep space activities rather than Earth-centric work that is better handled by other agencies."

"Trump to scrap Nasa climate research in crackdown on 'politicized science', The Guardian

"Bob Walker, a senior Trump campaign adviser, said there was no need for Nasa to do what he has previously described as "politically correct environmental monitoring". "We see Nasa in an exploration role, in deep space research," Walker told the Guardian. "Earth-centric science is better placed at other agencies where it is their prime mission. "My guess is that it would be difficult to stop all ongoing Nasa programs but future programs should definitely be placed with other agencies. I believe that climate research is necessary but it has been heavily politicized, which has undermined a lot of the work that researchers have been doing. Mr Trump's decisions will be based upon solid science, not politicized science."

Yes, Donald Trump did call climate change a Chinese hoax, Politifact

"At one point, Clinton said, "Donald Trump says climate change is a hoax invented by the Chinese." Did he? Yes, though he later said it was a joke. The original source of this claim was a tweet Trump sent on Nov. 6, 2012, as we noted in a January 2016 fact-check of a similar claim by Clinton's Democratic opponent, Bernie Sanders."

Trump admits 'some connectivity' between climate change and human activity, CNN

"President-elect Donald Trump conceded Tuesday there is "some connectivity" between human activity and climate change and wavered on whether he would pull the United States out of international accords aimed at combating the phenomenon, which scientists overwhelmingly agree is caused by human activity."

Keith's note: Last week a number of articles appeared with the startling (at least to the authors) news that President Trump was going to cut all of NASA's Earth science programs. The authors based this arm waving on quotes in the Guardian by on-again/off-again/on-again Trump transition team advisor Bob Walker. This is not the first time Walker has said something like this. Back in the middle of October, in a Space News op ed, Walker made similar comments. Other than these two comments by Walker we have little else to go on except some off-handed, indecisive quotes from Trump himself on climate change. So - will Trump gut NASA space science? We only have some hints from someone who may or may not actual know what Trump is going to do. If Trump does take a run at NASA's Earth science programs he'll have allies such as Sen. Ted Cruz and House Science Committee Chair Lamar Smith who have been going after climate-based research funding for years. Then again, Trump may find himself consumed by far more pressing issues. We won't know until a Trump space policy emerges and a Trump team is installed on the 9th floor at NASA Headquarters.

GAO Urges Deeper FAA Insight into Aerial and Suborbital Vehicles

FAA Should Examine How to Appropriately Regulate Space Support Vehicles, GAO

"Company officials GAO interviewed identified potential uses for "space support vehicles"- which include a variety of aircraft from high-performance jets to balloons and the aircraft portion of a hybrid launch systems (a vehicle that contains elements of both an aircraft and a rocket-powered launch vehicle) - but the size of the market for these uses is unclear. Company officials said they plan to use space support vehicles to train spaceflight participants and to conduct research in reduced gravity environments. For example, some company officials said they would like to use high-performance jets to train future spaceflight participants by exposing them to physiological and psychological effects encountered in spaceflight. Other company officials said they would like to use space support vehicles to research how objects or people react in reduced gravity environments. It is difficult to know the size of the market for spaceflight training and research as GAO found no studies on these markets. However, stakeholders said they expect interest in research to increase."

Ring Scan


Scroll right and you can cruise along the icy rings of Saturn. This high resolution scan is a mosaic of images presented in natural color. The images were recorded in May 2007 over about 2.5 hours as the Cassini spacecraft passed above the unlit side of the rings. To help track your progress, major rings and gaps are labeled along with the distance from the center of the gas giant in kilometers. The alphabetical designation of Saturn's rings is historically based on their order of discovery; rings A and B are the bright rings separated by the Cassini division. In order of increasing distance from Saturn, the seven main rings run D,C,B,A,F,G,E. (Faint, outer rings G and E are not imaged here.) Four days from now, on November 29, Cassini will make a close flyby of Saturn's moon Titan and use the large moon's gravity to nudge the spacecraft into a series of 20 daring, elliptical, ring-grazing orbits. Diving through the ring plane just 11,000 kilometers outside the F ring (far right) Cassini's first ring-graze will be on December 4. via NASA http://ift.tt/2fbgea1

Wasting The International Space Station On The #JourneyToMars

After Scott Kelly's flight, NASA plans five more one-year missions, Ars Technica

"During a subcommittee meeting of NASA's Advisory Committee earlier this month, former space shuttle program manager Wayne Hale asked Paloski why the space agency wasn't considering missions longer than a year to truly reflect the time astronauts would have to spend away from Earth were they to go to Mars or other destinations beyond cislunar orbit. "It seems to me that you're not there yet in determining the health factors for a 30-month voyage," Hale said. In a follow-up interview, the Human Research Program's chief scientist, John Charles, explained to Ars that from a logistic and scientific standpoint, the one-year missions offered a reasonable compromise. The station probably has seven years left in its lifetime, and because of advanced planning requirements, there would be the capability to fly, at most, just a single two- or three-year mission during that time. Not only would this adversely affect crew rotations, there's also the question of statistical significance from just two data points. "Darn it, we biologists like to have statistical validity," Charles explained. "We have discussed it internally and really think we're going to be pushing our luck to get five more one-year missions during the station's lifetime, to get a statistically significant database."

Keith's note: I love it when NASA talks about science and statistics. Gee, no one at JSC complained when they flew one, single, elderly person (John Glenn) for "science" - once i.e. N=1 and they have not repeated that experiment in the following 20 years. Has anyone seen the data? As a former NASA space biologist who used to run peer reviews of this sort of research, I totally understand the need for larger research specimen numbers. But when you take all of the informed consent regulations and risk models that NASA uses into account, sending humans to Mars on a multi-year mission, without any actual experience flying humans in space for that long would be unethical - again, according to NASA's own established procedures.

But if NASA decided to look to other exploration modalities such as mountaineering and polar research - and officially accepted different ways of parsing - and then allowing crew members to personally accept medical risk in exchange for the chance to explore, maybe they could save themselves a lot of time and effort. NASA can't have it both ways. They ask for the money to build all of this incredibly capable stuff in space then they are afraid to use it for the very purposes that it was supposedly built.

http://ift.tt/2gggVuBI spent a month living at 17,600 feet at Everest Base Camp while my friend, astronaut Scott Parazynski (who was also John Glenn's orbital doctor) risked his life to reach the summit. He trained as much as he could but in the end he was going to do something he had not done before. In the end it was his choice. He signed waivers in order to do this. While I was much safer at Base Camp, I was still at heightened physical risk to due to my age and my prolonged presence at that altitude. But I signed waivers too. I watched two immense avalanches a few thousand feet from my tent. One of them killed a person whose tent was near mine. Years later an avalanche killed people in the precise location where Scott and I pitched our tents for a month.

You can prepare all you want for stuff like this but at some point you just have to sign off on the risk and go for it. NASA cannot seem to decide whether it truly wants to accept the risk inherent in the human exploration of other worlds - or just study it incessantly. Until it does we'll all be stuck with half-hearted, semi-relevant research on the ISS. And then the ISS will be gone.

Here's a book from an event John Grunsfeld and I put together back in 2004 on this topic for NASA: "Risk and Exploration". Its not as if people at NASA have not talked about risk. Rather its whether they really want to make the same tough choices that other explorers do.

Guessing About Military TrumpSpace

Under Trump, GOP to Give Space Weapons Close Look, Roll Call

"Coming soon are a greater number of more capable anti-missile interceptors and radars deployed around the globe - on land, at sea and possibly in space, say these legislators and experts, several of whom have consulted with President-elect Donald Trump's advisers. ...Trump's thoughts on missile defense and military space programs have gotten next to no attention, as compared to the president-elect's other defense proposals, such as growing the Army and building more warships. As a candidate, Trump said little on the subject."

Keith's note: I'm sure that all of the experts mentioned in this article know how these systems work and are talking to people who talk to people who might talk to Trump's people. But at the present time there is no Trump space policy. So, at best, this is all semi-informed speculation. But, given other rhetoric associated with those lawmakers who will be asking questions at future hearings, it is not idle speculation to expect that more of a focus on overt weaponry in space may be on the horizon.

ISS Daily Summary Report – 11/22/2016

Waste and Hygiene Compartment (WHC) Maintenance:  Ground specialists met to discuss the WHC leak that occurred yesterday.  Based on review of the imagery the crew took during the cleanup, the ground specialists determined the most likely source of the leak to be a hydroconnector on the Urine Valve Block, but determined that since all of the contaminated hardware would need to be replaced there was not a significant benefit to performing troubleshooting to isolate the root cause of the leak.  Today, the crew replaced the Pump Separator, Urine Valve Block, several hoses and a data cable.  The WHC was activated, checked out and is go for nominal operations. Fluid Shifts Before, During and After Prolonged Space Flight and Their Association with Intracranial Pressure and Visual Impairment (Fluid Shifts): Today, a 48S crewmember began the first part of the Flight Day 45 (FD-45) Fluid Shifts data collection.  Upon wakeup he collected baseline saliva, urine, and with another crewmember acting as operator collected blood samples that were inserted into Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) prior to ingesting a Sodium Bromide (NaBr) tracer.  Throughout the day, the crew will perform more urine, blood, and saliva collections, inserting those samples into MELFI as well.  Fluid Shifts investigates the causes for severe and lasting physical changes to astronaut’s eyes. Because the headward fluid shift is a hypothesized contributor to these changes, reversing this fluid shift with a lower body negative pressure device is investigated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and eye damage. Water Monitoring Suite (WMS) and Aquapad Sampling: In coordination with regular Environmental Health System (EHS) water sampling, the crew is scheduled to perform the ESA sponsored Aquapad (Paper Analytical Device) technological demonstration and sampling using the Microbial Monitoring System (MMS) portion of the WMS experiment.  By using the same water collected for the EHS sample, ground teams can evaluate the capabilities of the new hardware.  For the MMS, the crew reviewed an On-Board Training (OBT) video then configured the hardware to sample a low and high DNA concentration sample using the Razor Polymerase Chain Reaction (PCR) Microbial Monitoring System.  The WMS is a set of hardware that monitors microbes, silica and organic material in the water supply on the ISS. The hardware ensures crew members can test and monitor the safety of their water supplies on future space missions, especially on long-duration missions to Mars, asteroids or other destinations where Earth-based testing would be difficult or impossible. Aquapad is a new approach developed by France’s CNES space agency: paper impregnated with powdered growth medium creates a 3D petri dish. When water is added, the microbes form colored spots revealing their locations. Using a tablet computer application the crew will photograph the dots to calculate precisely how many bacteria are present.  GeoFlow-2: The crew activated the Multi-purpose Computer and Communications (MPCC) laptop, Fluid Science Laboratory (FSL) rack, installed Anti Vibration Mount (AVM) brackets then released the Facility Core Element in preparation for free-floating microgravity science inside the FSL.  Geoflow-2 studies heat and fluid flow currents within the Earth’s mantle. Geoflow-2 aims to improve computational methods that scientists and engineers use to understand and predict the processes in the Earth’s mantle that lead to volcanic eruptions, plate tectonics and earthquakes. Spacecraft Fire Safety (Saffire)-II: Operations started onboard Cygnus about 2325 GMT yesterday and wrapped up about 0230 GMT when the post-test flow visualization completed. Preliminary telemetry indicated that data and images were recorded as expected for all 9 samples and flow visualization. The Saffire-II hardware performed nominally with no apparent issues.  The team is downlinking the sensor and image data and begin analysis of the dataset later today. Japanese Experiment Module (JEM) Stowage Wire Kit Installation:  The crew started the activities to install the JEM Stowage Wire Kit.  This Kit will make additional stowage available in the area under the JEM Airlock (JEMAL).  The crew completed the activity to gather the hardware, but the rest of the activity was deferred due to work on the WHC. Emergency Role/Responsibility Review:  The crew performed a review of the Emergency General Instructions for response to emergencies and roles of each crew member.  This review included a discussion of roles of Soyuz Commander, ISS Commander and each crewmember and strategies for working through the response to Emergencies.  Mobile Servicing System (MSS) Operations:  The Robotics Ground Controllers translated the Mobile Transporter (MT) from Worksite (WS) 6 to WS7.  Controllers will walk-off the Space Station Remote Manipulator System (SSRMS) from Mobile Base System (MBS) 3 to the MBS 1 grapple fixture.  They will then unstow Special Purpose Dexterous Manipulator (SPDM).  These activities are in preparation for Robotic External Leak Locator (RELL) operations planned to start Monday 28-November. Today’s Planned Activities All activities were completed unless otherwise noted.

Plutos Sputnik Planum


Is there an ocean below Sputnik Planum on Pluto? The unusually smooth 1000-km wide golden expanse, visible in the featured image from New Horizons, appears segmented into convection cells. But how was this region created? One hypothesis now holds the answer to be a great impact that stirred up an underground ocean of salt water roughly 100-kilometers thick. The featured image of Sputnik Planum, part of the larger heart-shaped Tombaugh Regio, was taken last July and shows true details in exaggerated colors. Although the robotic New Horizons spacecraft is off on a new adventure, continued computer-modeling of this surprising surface feature on Pluto is likely to lead to more refined speculations about what lies beneath. via NASA http://ift.tt/2ghUTco

NASA Is Reinventing Snack Bars Because ...

Space Food Bars Will Keep Orion Weight Off and Crew Weight On

"To help reduce the amount of supplies Orion will carry for its crew, scientists are developing a variety of food bars that astronauts can eat for breakfast during their spaceflight missions. In the United States, it's common for people to substitute an energy bar or shake for breakfast, or to skip the meal all together. Food scientists determined that developing a single calorically dense breakfast substitution can help meet mass reduction requirements."

GAO Reports On Commercial Launch Insurance

Commercial Space Launch Insurance: Views Differ on Need for Change to Insurance Approach but Clarification Is Needed

"Stakeholders in the space launch industry are divided on the need to change the current insurance approach, in which insurance for spaceports is not required but can be negotiated through contracts between launch companies, which operate launch vehicles, and spaceport operators, which run spaceports. Stakeholders identified some positive aspects of the current insurance approach - for example, some said that negotiating contracts specific to each launch allows for greater flexibility. However, they also raised concerns, including a lack of certainty about coverage for potential damage."

ISS Daily Summary Report – 11/21/2016

Urine Processing Assembly (UPA) Potential Wastewater Storage Tank Assembly (WSTA) Leak: This morning an unexpected caution indicating “UPA Potential WSTA leak” annunciated following use of the Waste and Hygiene Compartment (WHC). The crew isolated the UPA and WHC was configured to internal [EDV] to isolate the system. An on-orbit inspection by the crew showed pretreated urine on the urine valve block. The crew cleaned up the pretreated urine and closed out the WHC. WHC is No-Go for use and ground specialists are working the follow-on plan.  The crew has been authorized to use the Russian toilet.  Due to the leak, the planned WSTA leak was aborted. Cygnus Departure: Cygnus was unberthed nominally from the ISS at 5:23 AM CST and was released at 7:22 AM CST. Post departure science objectives for Cygnus including Saffire-II and NanoRacks CubeSat deployments.  Cygnus re-entry is planned for November 27. Later today, Saffire-II will initiate and conduct a roughly 2-hour experiment session, followed by multi-day data downlinks. The Saffire-II experiment attempts to quantify the flammability of several materials in microgravity, and compares them to flammability limits in normal gravity.  The NanoRacks CubeSat Deployer – External (NRCSD-E) deploy is planned November 25, at which time the Cygnus will be 100 km above the ISS, this will be the the first time NRCSDs deploy above the ISS. A total of 4 LEMUR-2 satellites will deploy from the Cygnus vehicle.  The NanoRacks-LEMUR-2 satellites are part of a remote sensing satellite constellation that proves global ship tracking and weather monitoring. Marrow Collections: The crew performed their first blood collections in support of the Canadian Space Agency’s (CSA’s) Marrow experiment.  After collecting, the blood was spun in the Refrigerated Centrifuge and stored in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).   The Marrow investigation looks at the effect of microgravity on the bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on the bone marrow and the blood cells that are produced in the bone marrow.  Fine Motor Skills (FMS): The 49Soyuz USOS crew performed their first FMS sessions this morning.  FMS is performed regularly during the crews’ on-orbit stay, with several sessions within the first week, then as the mission progresses, more time elapses between sessions.  Each FMS session involves the crew performing a series of interactive tasks on a touchscreen tablet. This investigation is critical during long-duration space missions, particularly those skills needed to interact with technologies required in next-generation space vehicles, spacesuits, and habitats. The crewmember’s fine motor skills are also necessary for performing tasks in transit or on a planetary surface, such as information access, just-in-time training, subsystem maintenance, and medical treatment. MATISS Installation: The crew installed four MATISS sample holders in the Columbus module. The MATISS experiment investigates the antibacterial properties of materials in space to see if future spacecraft could be made easier to clean. The experiment aims to understand the mechanisms of attachment of biofilms in microgravity conditions. The optimization of the internal surfaces of the International Space Station (ISS) is a challenge. The first objective is to simplify MATISS decontamination operations to save time crew. The second objective relates to space exploration: the validation of these innovative surfaces would indeed have new assets for the development of future spacecraft, including in the context of long journeys.  Microgravity Science Laboratory (MSL) Sample Cartridge Assembly (SCA) Installation: The crew inserted a new cartridge in the MSL, located in the Material Science Research Rack (MSRR), today.  The sample processing date is scheduled for later in the increment.  The Batch-2b of the Materials Science Laboratory Sample Cartridge Assemblies (MSL SCA-Batch 2b-ESA) serves two projects investigating how different phases organize in a structure when metallic alloys are solidified. The METCOMP project studies the phase formed by the reaction of the remaining liquid phase with an already formed solid, to form a second solid phase on cooling. For this purpose, Bronze (Copper-Tin Alloys) of different compositions will be processed. The other project, Solidification along a Eutectic path in Ternary Alloys (SETA), looks at how two phases that form together organize into lamellar, or fibre, structures when cooling Aluminium (Copper-Silver Alloys). Both projects will provide benchmark samples that will enable to test numerical models that aim to predict these structures.  Mobile Servicing System (MSS) Operations:  Following the successful Cygnus unberth and release, the Robotics Ground Controllers performed a video survey of the Node 1 Nadir Common Berthing Mechanism (CBM).  They then walked the Space Station Remote Manipulator System (SSRMS) off Node 2 onto Mobile Base System (MBS) Power Data Grapple Fixture 3 (PDGF3) and maneuvered the SSRMS to a Mobile Transporter (MT) translation configuration.  Currently the Robotics Ground Controllers are performing additional troubleshooting of the SSRMS End B Camera Light Pan/Tilt Unit (PTU) Assembly (CLPA).

Nova over Thailand


A nova in Sagittarius is bright enough to see with binoculars. Detected last month, the stellar explosion even approached the limit of naked-eye visibility last week. A classical nova results from a thermonuclear explosion on the surface of a white dwarf star -- a dense star having the size of our Earth but the mass of our Sun. In the featured image, the nova was captured last week above ancient Wat Mahathat in Sukhothai, Thailand. To see Nova Sagittarius 2016 yourself, just go out just after sunset and locate near the western horizon the constellation of the Archer (Sagittarius), popularly identified with an iconic teapot. Also visible near the nova is the very bright planet Venus. Don’t delay, though, because not only is the nova fading, but that part of the sky is setting continually closer to sunset. via NASA http://ift.tt/2gBQ3dz

Heads Up NASA Employees

Trump has a plan for government workers. They're not going to like it., Washington Post

"President-elect Donald Trump and the Republican-controlled Congress are drawing up plans to take on the government bureaucracy they have long railed against, by eroding job protections and grinding down benefits that federal workers have received for a generation. Hiring freezes, an end to automatic raises, a green light to fire poor performers, a ban on union business on the government's dime and less generous pensions - these are the contours of the blueprint emerging under Republican control of Washington in January. These changes were once unthinkable to federal employees, their unions and their supporters in Congress. But Trump's election as an outsider promising to shake up a system he told voters is awash in "waste, fraud and abuse" has conservatives optimistic that they could do now what Republicans have been unable to do in the 133 years since the modern civil service was created."

NASA Slaps Down Climate Denier Down Under

NASA chief slaps down climate sceptic senator Malcolm Roberts: 'You hold a number of misconceptions', North Queensland Register

"A senior NASA official has taken the extraordinary step of personally rejecting the claims of One Nation senator Malcolm Roberts that the agency had falsified key data to exaggerate warming in the Arctic. Gavin Schmidt, director of NASA's Goddard Institute for Space Studies, told Senator Roberts he was "mistaken" in his assertion that the US agency had "removed" Arctic data to mask warming in the 1940s."

NGC 4414: A Flocculent Spiral Galaxy


How much mass do flocculent spirals hide? The featured true color image of flocculent spiral galaxy NGC 4414 was taken with the Hubble Space Telescope to help answer this question. The featured image was augmented with data from the Sloan Digital Sky Survey (SDSS). Flocculent spirals -- galaxies without well-defined spiral arms -- are a quite common form of galaxy, and NGC 4414 is one of the closest. Stars and gas near the visible edge of spiral galaxies orbit the center so fast that the gravity from a large amount of unseen dark matter must be present to hold them together. Understanding the matter and dark matter distribution of NGC 4414 helps humanity calibrate the rest of the galaxy and, by deduction, flocculent spirals in general. Further, calibrating the distance to NGC 4414 helps humanity calibrate the cosmological distance scale of the entire visible universe. via NASA http://ift.tt/2gsbMns

Trump's Chief Strategist Tried To Make A SciFi Space Movie Based On Shakespeare

For Trump adviser Stephen Bannon, fiery populism followed life in elite circles, Washington Post

"In the early 1990s, he and [Julia] Jones, a screenwriter, struck up a conversation in a restaurant and decided to try their hand at adapting Bannon's idea for a version of Shakespeare's "Titus Andronicus" set in space. That script went nowhere, but the two went on to work on dozens of film and television projects together."

Titus Andronicus, Wikipedia

"Titus Andronicus is a tragedy by William Shakespeare, believed to have been written between 1588 and 1593, probably in collaboration with George Peele. It is thought to be Shakespeare's first tragedy, and is often seen as his attempt to emulate the violent and bloody revenge plays of his contemporaries, which were extremely popular with audiences throughout the 16th century."

IC 5070: A Dusty Pelican in the Swan


The recognizable profile of the Pelican Nebula soars nearly 2,000 light-years away in the high flying constellation Cygnus, the Swan. Also known as IC 5070, this interstellar cloud of gas and dust is appropriately found just off the "east coast" of the North America Nebula (NGC 7000), another surprisingly familiar looking emission nebula in Cygnus. Both Pelican and North America nebulae are part of the same large and complex star forming region, almost as nearby as the better-known Orion Nebula. From our vantage point, dark dust clouds (upper left) help define the Pelican's eye and long bill, while a bright front of ionized gas suggests the curved shape of the head and neck. This striking synthesized color view utilizes narrowband image data recording the emission of hydrogen and oxygen atoms in the cosmic cloud. The scene spans some 30 light-years at the estimated distance of the Pelican Nebula. via NASA http://ift.tt/2frkU7N

TrumpSpace: Good News and Bad News For Everyone - Maybe

Big change on the horizon for NASA under Trump, Lori Garver, The Hill

"NASA Administrator Charlie Bolden's perceived lack of enthusiastic support of the White House agenda gave an opening to the opposition. Without a willingness to take on these special interests, the administration made a Faustian bargain to secure congressional support for Earth sciences, technology and commercial crew, in exchange for support of developing a large expendable rocket (the Space Launch System or SLS) and deep space capsule (Orion) for human spaceflight. While these parochial interests still exist, a Trump White House has the opportunity to more effectively defend its own agenda. Former Speaker Newt Gingrich (R-Ga.), one the president-elect's most senior advisers, understands space issues and is a strong believer in commercial space development as the goal of space settlement. Former Congressman Robert Walker (R-Pa.) and former National Space Council executive director Mark Albrecht share many of Gingrich's views on the NASA bureaucracy and goals for NASA. Neither Albrecht nor Walker appear to be anxious to return to government service, but will certainly select a like-minded administrator."

NASA Under Trump, Planetary Society

"Of the $1 trillion of "discretionary" spending, more than half is spent on national defense. Everything else the government does - scientific research, border control, education, environmental protection, federal judges, infrastructure, NASA - comes from this non-defense discretionary amount. This has also been targeted for wholesale cuts by the Trump campaign in order to help pay for their large tax cut. These cuts, along with the reinstitution of the sequester (across-the-board cuts to all federal agencies), would collapse non-defense discretionary spending to its lowest point in modern history. This budgetary scenario potentially spells doom for NASA and its ambitions. The congressional subcommittee responsible for NASA - Commerce, Justice, and Science - is also responsible for the NSF, NOAA, the FBI, the Justice Department, and Commerce Department, and the Census, among others."

How Donald Trump's win could change the trajectory of commercial space ventures, Geekwire

"President-elect Donald Trump's advisers say they want to rely more on commercial ventures to pioneer the space frontier - but some of those ventures' high-profile backers aren't exactly in line with other parts of Trump's policy agenda. For example, SpaceX's billionaire CEO, Elon Musk, sees climate change as the biggest challenge facing humanity on Earth and has said a tax on carbon emissions is as necessary as garbage collection fees. In contrast, Trump has said concerns about climate change are a hoax perpetrated by the Chinese, and has vowed to "cancel" U.S. participation in the recently established Paris climate pact. (The Chinese say they're trying to set Trump straight on that point.) Amazon billionaire Jeff Bezos, who founded Blue Origin to send passengers and payloads into space, is also the owner of The Washington Post. The Post, Amazon and Bezos were all caught up in Trump's ire during the campaign. On the flip side of the issue, there's at least one space billionaire who can hardly wait for Trump to get into office: Robert Bigelow, the founder of Bigelow Aerospace."
