The Iris Nebula in a Field of Dust


What blue flower grows in this field of dark interstellar dust? The Iris Nebula. The striking blue color of the Iris Nebula is created by light from the bright star SAO 19158 reflecting off of a dense patch of normally dark dust. Not only is the star itself mostly blue, but blue light from the star is preferentially reflected by the dust -- the same affect that makes Earth's sky blue. The brown tint of the pervasive dust comes partly from photoluminescence -- dust converting ultraviolet radiation to red light. Cataloged as NGC 7023, the Iris Nebula is studied frequently because of the unusual prevalence there of Polycyclic Aromatic Hydrocarbons (PAHs), complex molecules that are also released on Earth during the incomplete combustion of wood fires. The bright blue portion of the Iris Nebula spans about six light years. The Iris Nebula, pictured here, lies about 1300 light years distant and can be found with a small telescope toward the constellation of Cepheus. via NASA https://ift.tt/2OwUoM8

OSTP Just Said Something About Outer Space

FY 2020 Administration Research and Development Budget Priorities, OSTP

"American Space Exploration & Commercialization - Research and innovation in space have a direct impact on Earth, generating advancements in our basic understanding of the universe and our own planet, and inspiring the next generation of scientists and engineers. Research investments should be focused on ensuring American leadership in space for long-duration spaceflight, in-space manufacturing, in-situ resource utilization, longterm cryogenic fuel storage and management, and advanced space-related power and propulsion capabilities. Agencies should prioritize demonstrations and flight tests to ensure an industrial base for commercial activity in space and on celestial bodies. One area of potential scientific and commercial importance is microgravity-related research that has the potential for near-term breakthroughs in biopharmaceuticals and materials science. Finally, agencies should seek opportunities to work with advanced materials, additive manufacturing, optical communications, and machine learning-capabilities that have broad potential applications in space and on Earth."

Pluto Huggers Are Upset By The Use Of The Term "Planet 9"

Keith's note: (Sigh) This had to happen. Now there are planetary scientists who actually think that use of the term "Planet 9" is "insensitive" - and they even have a petition urging support for their barely-contained outrage. If the Pluto huggers were serious about the responsibility that goes with naming things on worlds they should have thought twice about naming surface features on Pluto after things such as a SciFi monster named "Cthulhu" whose head is shaped like calamari. And they were all nicknaming features like crazy before the IAU even had a chance to weigh in. But wait - weren't many of the same undersigned complainers recently complaining about the IAU naming process - and demanding a greater role for public input in this process? Well, that is what is happening: there may be a large planet lurking in the outer solar system and some scientists and the public want to call it "Planet 9". And they are. C'mon Alan Stern. You can't have it both ways. Just sayin'

"ON THE INSENSITIVE USE OF THE TERM "PLANET 9" FOR OBJECTS BEYOND PLUTO: We the undersigned wish to remind our colleagues that the IAU planet definition adopted in 2006 has been controversial and is far from universally accepted. Given this, and given the incredible accomplishment of the discovery of Pluto, the harbinger of the solar system's third zone - the Kuiper Belt - by planetary astronomer Clyde W. Tombaugh in 1930, we the undersigned believe the use of the term "Planet 9" for objects beyond Pluto is insensitive to Professor Tombaugh's legacy. We further believe the use of this term should be discontinued in favor of culturally and taxonomically neutral terms for such planets, such as Planet X, Planet Next, or Giant Planet Five."

Get Ready For The Space Force

Pentagon not waiting for Congress to create space force: report, The Hill

"The Department of Defense is reportedly planning to create a new Space Operations Force in upcoming months at the direction of President Trump, despite lacking congressional approval for the new military service branch. Defense One reports that the Pentagon has laid out its plan to create the new Space Force in a 14-page report that will be given to lawmakers later this week. Defense One reports that it has reviewed a draft copy of the report dated July 30. The plan as it is currently laid out in the draft includes creating a Space Force with four parts, three of which will be established over the next few months. A combatant command for space, a joint agency that will purchase military satellites and a new warfighting community are among the three parts to be established in the near future."

Layers of the South Pole of Mars


What lies beneath the layered south pole of Mars? A recent measurement with ground-penetrating radar from ESA's Mars Express satellite has detected a bright reflection layer consistent with an underground lake of salty water. The reflection comes from about 1.5-km down but covers an area 200-km across. Liquid water evaporates quickly from the surface of Mars, but a briny confined lake, such as implied by the radar reflection, could last much longer and be a candidate to host life such as microbes. Pictured, an infrared, green, and blue image of the south pole of Mars taken by Mars Express in 2012 shows a complex mixture of layers of dirt, frozen carbon dioxide, and frozen water. via NASA https://ift.tt/2Assi1K

Yet Another Feel Good Space Bill That Does Not Pay For Itself

Sens. Cruz, Nelson, Markey Introduce Space Frontier Act

"U.S. Sens. Ted Cruz (R-Texas), Bill Nelson (D-Fla.), and Ed Markey (D-Mass.), members of the U.S. Senate Committee on Commerce, Science, and Transportation, on Wednesday introduced the Space Frontier Act (S. 3277). This commercial space bill builds upon the 2015 Commercial Space Launch Competitiveness Act by streamlining and reforming the regulatory framework for commercial space launch and Earth observation operations, which is crucial to maintaining American leadership in space. The bill also extends the operation and utilization of the International Space Station (ISS) through 2030 to ensure that the U.S. is getting the maximum return on American taxpayer investment to avoid creating a leadership vacuum in low Earth orbit."

S. 3277

Keith's note: Contain your enthusiasm, space fans. This grab bag of ideas does not actually fund itself. It may well make it easier for space commerce to proceed with various commercial ventures by cutting some red tape. But in terms of the things this bill wants NASA to pay for (like ISS through 2030) this legislation just says that its OK to spend money on these things. Actually spending money to do these things is another matter entirely and is up to appropriators to argue about annually for the next 12 years or so. How NASA will be assured of the funding needed to fund ISS through 2030 while doing the whole Moon/Mars thing has yet to be addressed. Oh yes - what about Space Force?

CASIS Wastes Crew Time And Delays NASA's Human Spaceflight Research

NASA's Management and Utilization of the International Space Station

"NASA uses 76.6 percent of the Station's research resources, so it pays 76.6 percent of the U.S. Segment's operating costs. Although a significant portion of total Station research time, the NASA Authorization Act of 2010 requires at least 50 percent of these resources, including upmass and crew time, be allocated to the CASIS-managed National Laboratory, limiting the time and capabilities available to NASA for mitigating risks associated with future space exploration goals. While our prior work found that CASIS has used on average only 52.7 percent of the crew time allocated from September 2013 to April 2017, its use of crew time has increased since 2016 to 72.8 percent between March 2016 and September 2016 and 68.1 percent between September 2016 and April 2017.39 Any allocation unused by CASIS can be used by NASA for its own research."

OIG: NASA's Management of the Center for the Advancement of Science in Space (CASIS) (2018) earlier post

"CASIS will be allocated additional research hours when NASA adds an additional crew member to the Station in late 2018. However, given its performance to date, CASIS utilization rates for the National Lab will likely further diminish."

NASA's Space Station Commercialization Plans Collide WIth Reality

NASA's Management and Utilization of the International Space Station, NASA OIG

"Specifically, we question whether a sufficient business case exists under which private companies will be able to develop a self-sustaining and profit-making business independent of significant Federal funding within the next 6 years. Likewise, any extension of the ISS past 2024 would require continued funding in the neighborhood of $3-$4 billion annually to operate and maintain the Station - a significant portion of which could otherwise be redirected to develop systems needed for NASA's cislunar or deep space ambitions. In addition, extending the Station's life would challenge NASA to manage the risks associated with continued operation of the Station's aging systems and infrastructure. Furthermore, any extension will require the support of NASA's international partners, whose continued participation hinges on issues ranging from geopolitics to differing space exploration goals."

Journey to the Center of the Galaxy


What wonders lie at the center of our Galaxy? In Jules Verne's science fiction classic A Journey to the Center of the Earth, Professor Liedenbrock and his fellow explorers encounter many strange and exciting wonders. Astronomers already know of some of the bizarre objects that exist at our Galactic center, including like vast cosmic dust clouds, bright star clusters, swirling rings of gas, and even a supermassive black hole. Much of the Galactic Center is shielded from our view in visible light by the intervening dust and gas, but it can be explored using other forms of electromagnetic radiation. The featured video is actually a digital zoom into the Milky Way's center which starts by utilizing visible light images from the Digitized Sky Survey. As the movie proceeds, the light shown shifts to dust-penetrating infrared and highlights gas clouds that were recently discovered in 2013 to be falling toward central black hole. In 2018 May, observations of a star passing near the Milky Way's central black hole showed, for the first time, a gravitational redshift of the star's light -- as expected from Einstein's general relativity. via NASA https://ift.tt/2uXMint

Mars Opposition


Look opposite the Sun in the sky tonight and you'll see Mars at its brightest. Also within days of its closest approach Mars rises at sunset, near its brightest and best for telescopic observers too, except for the dust storm still blanketing the Red Planet. These two Hubble Space Telescope images compare Mars' appearance near its 2016 and 2018 oppositions. In 2016 the martian atmosphere was clear. Captured just days ago, the 2018 image shows almost the same face of Mars. Surface features obscured by dust, the planet's cloud enshrouded south pole is tilted more toward the Sun. Increased heat in the southern hemisphere spring and summer likely triggers planet wide dust storms. Of course, if you look opposite the Sun in the sky tonight, you'll also see a Full Moon near Mars.

The Edge On Spindle Galaxy


What kind of celestial object is this? A relatively normal galaxy -- but seen from its edge. Many disk galaxies are actually just as thin as NGC 5866, pictured here, but are not seen edge-on from our vantage point. A perhaps more familiar galaxy seen edge-on is our own Milky Way Galaxy. Cataloged as M102 and NGC 5866, the Spindle galaxy has numerous and complex dust lanes appearing dark and red, while many of the bright stars in the disk give it a more blue underlying hue. The blue disk of young stars can be seen extending past the dust in the extremely thin galactic plane. There is evidence that the Spindle galaxy has cannibalized smaller galaxies over the past billion years or so, including multiple streams of faint stars, dark dust that extends away from the main galactic plane, and a surrounding group of galaxies (not shown). In general, many disk galaxies become thin because the gas that forms them collides with itself as it rotates about the gravitational center. The Spindle galaxy lies about 50 million light years distant toward the constellation of the Dragon (Draco). via NASA https://ift.tt/2A7FIjr

Cerealia Facula


Cerealia Facula, also known as the brightest spot on Ceres, is shown in this stunning mosaic close-up view. The high-resolution image data was recorded by the Dawn spacecraft, in a looping orbit, from altitudes as low as 34 kilometers (21 miles) above the dwarf planet's surface. Cerealia Facula is about 15 kilometers wide, found in the center of 90 kilometer diameter Occator crater. Like the other bright spots (faculae) scattered around Ceres, Cerealia Facula is not ice, but an exposed salty residue with a reflectivity like dirty snow. The residue is thought to be mostly sodium carbonate and ammonium chloride from a slushy brine within or below the dwarf planet's crust. Driven by advanced ion propulsion on an 11-year mission, Dawn explored main-belt asteriod Vesta before traveling on to Ceres. But sometime between this August and October, the interplanetary spacecraft is expected to finally run out of fuel for its hydrazine thrusters, with the subsequent loss of control of its orientation, losing power and the ability to communicate with Earth. Meanwhile Dawn will continue to explore Ceres in unprecedented detail, and ultimately retire in its orbit around the small world. via NASA https://ift.tt/2Jzh2zV

Odd Hearings Ahead On Webb Space Telescope Problems

Keith's note: Next week there will be an unusual pair of hearings - same committee, same topic, but a different witness lineup. Have a look:

Panel 1 - Wednesday July 25, 2018 at 10:00 a.m.
Hon. Jim Bridenstine, administrator, NASA
Mr. Tom Young, chairman, JWST Independent Review Board

Panel 2 - Thursday, July 26, 2018 at 9:00 a.m.
Mr. Wesley Bush, chief executive officer, Northrop Grumman Corp.
Mr. Tom Young, chairman, JWST Independent Review Board

OK, so this is strange. Webb Space Telescope is more than a decade late and has busted its budget cap yet again - this time by $800 million - so much so that Congress is required, by law, to reauthorize the entire project. Oddly, the NASA Administrator (who pays for this project) and the CEO of Northrop Grumman (who gets paid for this project) are not testifying together - not even on the same day. But the JWST IRB chair will testify with both Bridenstine and Bush. Its almost as if NASA wants to get their viewpoint and that of the Webb IRB first and then Northrop Grumman has 24 hours to get their act together - except - Congress usually wants prepared testimony submitted a day or more in advance. Or maybe there is a lot of looming tension and Congress does not want a cage match between NASA and Northrop Grumman. Stay tuned.
