Twilight in a Western Sky


A slender crescent Moon and inner planets Venus and Mercury never wander far from the Sun in planet Earth's skies. In the fading evening twilight of March 18, they line up near the western horizon in this atmospheric skyscape. While the celestial scene was enjoyed around the world, this photo captures the trio, with fainter Mercury at the far right, above the crags of Big Bend National Park in southwest Texas. Tonight the Moon will be full though, and rise opposite the Sun. Look for it high in the sky at midnight, near bright star Spica. via NASA https://ift.tt/2uAl3ls

NASA Announces Senior Leadership Changes to Refocus Launch Readiness Efforts for Webb Telescope

"NASA's Science Mission Directorate (SMD) is taking essential steps to refocus efforts to ensure a successful mission for the agency's James Webb Space Telescope (JWST) after an independent assessment of remaining tasks revealed more time is needed for testing and integration to meet a new launch window of approximately May 2020. Webb is SMD's highest priority project and the largest international space science project in U.S. history. All of the observatory's flight hardware is now complete.

Iridium-5 Mission


On Friday, March 30 at 7:13 a.m. PDT, SpaceX successfully launched the Iridium-5 NEXT mission from Space Launch Complex 4E (SLC-4E) at Vandenberg Air Force Base in California. This was the fifth set of 10 satellites in a series of 75 total satellites that SpaceX will launch for Iridium’s next generation global satellite constellation, Iridium® NEXT. The satellites were deployed about an hour after launch.

Falcon 9’s first stage for the Iridium-5 mission previously supported the Iridium-3 mission from SLC-4E in October 2017. SpaceX did not attempt to recover Falcon 9’s first stage after launch.

Confusion At NASA Over The America First National Space Strategy

http://images.spaceref.com/news/2018/america.first.jpg

President Donald J. Trump is Unveiling an America First National Space Strategy

"AMERICA FIRST AMONG THE STARS: President Trump's National Space Strategy works within his broader national security policy by putting America's interests first."

Keith's note: At the USRA/SPI Moon exploration event yesterday in Washington D.C, I asked NASA HEOMD's Jason Crusan about the apparent mismatch between NASA policy and the recently-released White House Policy titled "America First National Space Strategy". I noted that HEOMD AA Bill Gerstenmaier told a NASA Advisory Council committee the other day said the whole Lunar Outpost Gateway thing can be done on a flat budget with no adjustment for inflation. Of course, NASA never does big projects on time or within budget - Space Station, Webb, SLS being prominent examples. But NASA sells the Gateway concept with a significant role for international partners and the private sector with lots of cooperation i.e. NASA does not call all the shots. This global approach does have some positive aspects for many people.

Yet the White House's "America First" space policy is rather blunt in its intention that it wants a space policy that "prioritizes American interests first and foremost, ensuring a strategy that will make America strong, competitive, and great" and "ensures that international agreements put the interests of American people, workers, and businesses first." This does not sound too much like cooperation. I asked Crusan how he reconciled these two different approaches. Crusan tossed lots of pop management phrases out (he was clearly unprepared to talk about this White House policy document). Then he made one cogent observation: "it's a balancing act".

Oh yes: There is no mention of this official White House space policy document at NASA.gov. Nor has NASA released anything about it to the media. Stay tuned for more "balancing".

Carved by a bright young star in Orion's dusty molecular clouds, NGC 2023 is often overlooked in favor of the nearby dramatic silhouette of the Horsehead Nebula. In its own right it is seen as a beautiful star forming emission and reflection nebula though, a mere 1500 light-years distant. Surprisingly colorful and complex filaments are detailed in this rare NGC 2023 portrait. Scattered points of emission are also from the region's Herbig-Haro objects, associated with the energetic jets from newborn stars.

NASA's Inconsistent Policy For Launching Large Payloads

NASA chief explains why agency won't buy a bunch of Falcon Heavy rockets, Ars Technica

"Since the launch of the Falcon Heavy rocket in February, NASA has faced some uncomfortable questions about the affordability of its own Space Launch System rocket. By some estimates, NASA could afford 17 to 27 Falcon Heavy launches a year for what it is paying annually to develop the SLS rocket, which won't fly before 2020. Even President Trump has mused about the high costs of NASA's rocket. On Monday, during a committee meeting of NASA's Advisory Council, former Space Shuttle Program Manager Wayne Hale raised this issue. Following a presentation by Bill Gerstenmaier, chief of human spaceflight for NASA, Hale asked whether the space agency wouldn't be better off going with the cheaper commercial rocket. ... One difficulty with Gerstenmaier's response to Hale's question is that NASA does not, in fact, yet have any "large-volume, monolithic pieces" that could only be launched by the Space Launch System."

Revised SpaceX Plan To Beat NASA Human Missions To Mars

Making Life Multi-Planetary, Elon Musk

"We are targeting our first cargo missions in 2022 - that's not a typo, although it is aspirational. We've already started building the system - the tooling for the main tanks has been ordered, the facility is being built and we will start construction of the first ship around the second quarter of next year. In about six to nine months we should start building the first ship. I feel fairly confident that we can complete the ship and be ready for a launch in about five years. Five years seems like a long time to me. The area under the curve of resources over that period of time should enable this time frame to be met, but if not this time frame, I think pretty soon thereafter. But that is our goal, to try to make the 2022 Mars rendezvous. The Earth-Mars synchronization happens roughly every two years, so every two years there is an opportunity to fly to Mars. Then in 2024 we want to try to fly four ships - two cargo and two crew."

NGC 253: Dusty Island Universe


Shiny NGC 253 is one of the brightest spiral galaxies visible, and also one of the dustiest. Some call it the Silver Dollar Galaxy for its appearance in small telescopes, or just the Sculptor Galaxy for its location within the boundaries of the southern constellation Sculptor. Discovered in 1783 by mathematician and astronomer Caroline Herschel, the dusty island universe lies a mere 10 million light-years away. About 70 thousand light-years across, NGC 253 is the largest member of the Sculptor Group of Galaxies, the nearest to our own Local Group of Galaxies. In addition to its spiral dust lanes, tendrils of dust seem to be rising from a galactic disk laced with young star clusters and star forming regions in this sharp color image. The high dust content accompanies frantic star formation, earning NGC 253 the designation of a starburst galaxy. NGC 253 is also known to be a strong source of high-energy x-rays and gamma rays, likely due to massive black holes near the galaxy's center.

What NASA loses without a permanent leader, The Verge

"Despite the backlash to Bridenstine's politician status, being the NASA administrator means mostly working with politicians, says Garver.

"You can't be an astrophysicist and a propulsion engineer; you got to trust your people to do that. Being able to advocate for your agency on the hill is a big part of it." .. "Because [Lightfoot] isn't the president's person, there is a loss of accountability," Jim Muncy, founder of PoliSpace, a space policy consulting agency, tells The Verge.

Do you recognize this constellation? Although it is one of the most recognizable star groupings on the sky, Orion's icons don't look quite as colorful to the eye as they do to a camera. In this 20-image digitally-composed mosaic, cool red giant Betelgeuse takes on a strong orange tint as the brightest star at the upper left. Orion's hot blue stars are numerous, with supergiant Rigel balancing Betelgeuse at the lower right, and Bellatrix at the upper right Lined up in Orion's belt are three stars all about 1,500 light-years away, born from the constellation's well-studied interstellar clouds. Below Orion's belt a reddish and fuzzy patch that might also look familiar -- the stellar nursery known as Orion's Nebula.

Bipartisan Congressional Letter Of Support For Bridenstine

Letter From House Members to Senate Leadership Regarding NASA Administrator Nominee Bridenstine

Keith's note: This letter was circulated by Rep. Babin and was signed by 61 members of the House - 12 of whom are Democrats. This would certainly seem to undermine Sen. Nelson's contention that Jim Bridenstine would be too political.

"We are keenly aware of how valuable NASA is, not only to our nation, but also the entire world. It would be a travesty to America's space program for it to remain leaderless at this critical time when America's space industry is making rapid advances that will set the course of space leadership for decades to come. This is why it is vitally important that the Senate take up and approve Jim Bridenstine's nomination. Jim Bridenstine has spent the bulk of his adult life in service to his country. His background is in naval aviation, flying the E2- C Hawkeye in Afghanistan and Iraq, and later the F-18 while also serving as an instructor at the Naval Strike and Air Warfare Center. He has been responsible for coordinating command and control of the battlefield from an airborne platform, with thousands of lives and billions of dollars affected by his decisions. In this service to his nation he has demonstrated both the technical capacity and leadership experience necessary to lead NASA."

Moon Monday: Looking back at the Moon from Apollo 17

Rotating Moon from LRO


No one, presently, sees the Moon rotate like this. That's because the Earth's moon is tidally locked to the Earth, showing us only one side. Given modern digital technology, however, combined with many detailed images returned by the Lunar Reconnaissance Orbiter (LRO), a high resolution virtual Moon rotation movie has been composed. The above time-lapse video starts with the standard Earth view of the Moon. Quickly, though, Mare Orientale, a large crater with a dark center that is difficult to see from the Earth, rotates into view just below the equator. From an entire lunar month condensed into 24 seconds, the video clearly shows that the Earth side of the Moon contains an abundance of dark lunar maria, while the lunar far side is dominated by bright lunar highlands. Currently, over 20 new missions to the Moon are under active development from four different countries, most of which have expected launch dates either this year or next. via NASA http://ift.tt/2FKI3Di

The Crab from Space


The Crab Nebula is cataloged as M1, the first object on Charles Messier's famous list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, expanding debris from the death explosion of a massive star. This intriguing false-color image combines data from space-based observatories, Chandra, Hubble, and Spitzer, to explore the debris cloud in X-rays (blue-white), optical (purple), and infrared (pink) light. One of the most exotic objects known to modern astronomers, the Crab Pulsar, a neutron star spinning 30 times a second, is the bright spot near picture center. Like a cosmic dynamo, this collapsed remnant of the stellar core powers the Crab's emission across the electromagnetic spectrum. Spanning about 12 light-years, the Crab Nebula is 6,500 light-years away in the constellation Taurus. via NASA http://ift.tt/2FIPDhW

The Plight Of The Citrus College Rocket Owls

CA's LGBTQ law blocks SoCal college rocket club from Alabama competition

"A Citrus College rocketry club may be reaching for the stars, but is coming up with a handful of politics. The Rocket Owls team has earned a coveted spot at the annual NASA Student Launch competition, where 60 college teams from across the country go head-to-head, building and launching high-altitude rockets. But the event is held in Huntsville, Alabama which is one of eight states now targeted by the California legislature's AB 1887. That law bans publicly funded travel to states deemed to discriminate against gay, lesbian, bisexual or transgender people."

Rocket Owls COmmit to NASA Competition Despite Being Barred From Final Launch, Clarion

"Of the other five California schools accepted into the program, UC Santa Cruz and UC Berkeley have confirmed they are attending. "We have not experienced any problems with being unable to compete." UC Berkeley's CalSTAR Outreach officer, Adam Huth, said, "Technically, I believe teams in California are allowed to compete, they may just be unable to receive funding for the trip itself."

AB 1887 (full text)

"Specifically, AB 1887 does not apply to state travel that is required for any of the following purposes: To comply with requests by the federal government to appear before committees."

Keith's note: Homer Hickam of Rocket Boys/October Sky fame came across an article from California's Citrus College's Clarion newspaper that their rocket team wasn't going to be allowed to come to Huntsville, Alabama for the Student Launch competition because of AB 1887 - even though they had successfully accomplished all requirements and had been invited by NASA.

Investigating further, Hickam learned that several University of California teams were coming to the Student Launch competition by using their own funds. When he discovered the Citrus College team had raised their own travel money but the college board and Superintendent had still ordered them not to go, Hickam was outraged.

After going back and forth with NASA officials and Chancellor Eloy Oakley of California Community Colleges, Oakley threw up his hands and said it was all Citrus College Superintendent Geraldine Perri's fault and the decision lay entirely in her hands. Hickam has tried to contact Superintendent Perri but she has not responded. Hickam is trying to bring all the parties together to let these fine young students (rocketowls.com) go to Huntsville and compete. Failing that, he's working to allow them to come as an unaffiliated team.

Hickam spoke to several students and employees of Citrus College and all seem to be afraid of Dr. Perri and what she might do. Anyone, they all said, who doesn't agree with her risks her ire. The rocket team has considered going to Huntsville as an independent team but fear if they do, Dr. Perri's wrath will cause their expulsion from the college and other penalties, including a permanent shut-down of the rocket club for future students. Most of the mentors of the rocket club are volunteers. Their permissions to go on-campus would likely also be removed.

The intent of AB 1887 certainly has clear, undisputed merit to battle discrimination that I fully support. But for Citrus College to use this law as a excuse to prevent students from travelling to this competition - using funds that are not from the government of the State of California or from personal accounts - is simply wrong. This is especially questionable when other California educational institutions have found a way for their student teams to participate using alternate sources of funding. Moreover the NASA Student Launch effort is an educational competition conducted on a national basis wholly operated by the Federal government, not by the state of Alabama. The Federal government - not the State of Alabama - invited the Rocket Owls to participate. Also, the bill refers to people who work in some capacity for the State of California. These are students - taxpayers - not employees - and they do not seek any funds from the State of California.

Let's hope that Citrus College management wakes up to the realization that their job is facilitating education - not blocking educational opportunities for their students. If you don't want to help your students, Geraldine Perri, fine. But at least allow these students to spend their own money to further their education.

The Seagull and The Duck


Seen as a seagull and a duck, these nebulae are not the only cosmic clouds to evoke images of flight. But both are winging their way across this broad celestial landscape, spanning almost 7 degrees across planet Earth's night sky toward the constellation Canis Major. The expansive Seagull (top center) is itself composed of two major cataloged emission nebulae. Brighter NGC 2327 forms the head with the more diffuse IC 2177 as the wings and body. Impressively, the Seagull's wingspan would correspond to about 250 light-years at the nebula's estimated distance of 3,800 light-years. At the lower right, the Duck appears much more compact and would span only about 50 light-years given its 15,000 light-year distance estimate. Blown by energetic winds from an extremely massive, hot star near its center, the Duck nebula is cataloged as NGC 2359. Of course, the Duck's thick body and winged appendages also lend it the slightly more dramatic popular moniker, Thor's Helmet. via NASA http://ift.tt/2tR9INp

No, Scott Kelly's Genes Were Not Changed

Astronaut's DNA no longer matches that of his identical twin, NASA finds, CNN

"Spending a year in space not only changes your outlook, it transforms your genes. Preliminary results from NASA's Twins Study reveal that 7% of astronaut Scott Kelly's genes did not return to normal after his return to Earth two years ago. The study looks at what happened to Kelly before, during and after he spent one year aboard the International Space Station through an extensive comparison with his identical twin, Mark, who remained on Earth. NASA has learned that the formerly identical twins are no longer genetically the same."

Keith's 14 March note: NO NO NO NO. The Kelly brothers are exactly the same genetically as they were the day they were born. No genes were "transformed". Their genes are the same as they were the day they were conceived. What changed during space travel was how some genes were expressed. Some genes were shut off. Some genes were activated, Some genes were expressed at different levels. I wish that science writers would take the time to talk to people who actually understand the topic. There are dozens of articles like this circulating right now that get the fundamental aspect of this research wrong. Also, FWIW, NASA needs to spend more time explaining what it is they are trying to say. As an actual space biologist I find all of this rather frustrating.

The Identical Astronaut Twins Are Still Identical

Keith's note: You may have seen a lot of stories recently in major news publications over the past week or so stating that the Kelly brothers now have different DNA or something to that effect. Not true. Another example of reporters writing stories about something that they simply do not understand (I am an actual biologist so I can say that). Scott Kelly's DNA did not change. How some of his DNA is expressed (or not expressed) changed as a result (apparently) of spending nearly a year in space. But again, his DNA did not change. He and his brother are just as identical genetically as they were before he left Earth. Here is what NASA JSC PAO sent to some news media (but not others) on this topic:

"Mark and Scott Kelly are still identical twins; Scott's DNA did not fundamentally change. What researchers did observe are changes in gene expression, which is how your body reacts to your environment. This likely is within the range for humans under stress, such as mountain climbing or SCUBA diving. The change related to only 7 percent of the gene expression that changed during spaceflight that had not returned to preflight after six months on Earth. This change of gene expression is very minimal. We are at the beginning of our understanding of how space flight affects the molecular level of the human body. NASA and the other researchers collaborating on these studies expect to announce more comprehensive results on the twins studies this summer."
