Hayabusa2 Ascends from Asteroid Ryugu


Will spacecraft Hayabusa2 be able to land safely on asteroid Ryugu? Since arriving in June, pictures show that the surface of kilometer-sized Ryugu is covered with boulders, so that finding a flat enough area for the bus-sized spacecraft to touch down is proving a challenge. In the featured video, the shadow of Japan's robotic Hayabusa2 can be seen on the rugged face of Ryugu while ascending last week from a touchdown rehearsal only 20 meters over the surface. Previously, small frisbee-sized landers detached from Hayabusa2, made contact with the diamond-shaped asteroid's surface, and started hopping around. Studying Ryugu could tell humanity not only about the minor planet's surface and interior, but about what materials were available in the early Solar System for the development of life. The touchdown of the Hayabusa2 mother ship is slated for early next year, hopefully followed by a soil sample collection for return to Earth. via NASA https://ift.tt/2zgx3aM

Big Court Win For The Thirty Meter Telescope

Embattled Thirty Meter Telescope scores big win in Hawaii's highest court, Nature

"Hawaii's supreme court has ruled in favour of building the Thirty Meter Telescope (TMT) atop the mountain Mauna Kea. The decision removes the last legal hurdle preventing the US$1.4-billion project from resuming construction on Hawaii's Big Island. "It is a tremendously important and significant decision that provides secure legal grounds to restart construction of this transformative facility," says Michael Balogh, an astronomer at the University of Waterloo in Canada who chairs an advisory committee that represents Canadian astronomers' interests in the TMT."

R Leporis: A Vampire's Star


Better known as Hind's Crimson Star, R Leporis is a rare star in planet Earth's night sky. It's also a shocking shade of red. The star's discoverer, 19th century English astronomer John Russell Hind, reported that it appeared in a telescope "... like a drop of blood on a black field." Located 1,360 light-years away in the constellation Lepus the star is a Mira-type variable, changing its brightness over a period of about 14 months. R Leporis is now recognized as a carbon star, a very cool and highly evolved red giant with an extreme abundance of carbon. Extra carbon in carbon stars is created by helium fusion near the dying stellar core and dredged up into the stars' outer layers. The dredge-up results in an overabundance of simple carbon molecules, like CO, CH, CN, and C2. While it's true that cool stars radiate most of their energy in red and infrared light, the carbon molecules strongly absorb what little blue light is left and give carbon stars an exceptionally deep red color. R Leporis is losing its carbon-rich atmosphere into the surrounding interstellar material through a strong stellar wind though, and could be near the transition to a planetary nebula. Oh, and Happy Halloween from the folks at APOD. via NASA https://ift.tt/2Rt7kU7

When Supporting Space Comes Back To Bite You

For the 7th Congressional District: Lizzie Pannill Fletcher, opinion, Houston Chronicle

"It's not that Culberson doesn't care about water. He does. But most of the time, he seems to care a bit more about the water on Europa, an icy moon orbiting Jupiter, than he does the water in the Addicks and Barker dams. Or in our bayous. Or in our homes. Culberson has expended untold political capital trying to force NASA to send probes to Europa in search of alien life. That's an admirable scientific mission, even if some planetary researchers think the limited resources could be better spent. Here on Earth, Houstonians can rest assured that Fletcher will prioritize human life over the extraterrestrial. That includes life-saving flooding policies that emphasize prevention over costly recovery."

Orionids Meteors over Inner Mongolia


Meteors have been shooting out from the constellation of Orion. This was expected, as October is the time of year for the Orionids Meteor Shower. Pictured here, over two dozen meteors were caught in successively added exposures last October over Wulan Hada volcano in Inner Mongolia, China. The featured image shows multiple meteor streaks that can all be connected to a single small region on the sky called the radiant, here visible just above and to the left of the belt of Orion, The Orionids meteors started as sand sized bits expelled from Comet Halley during one of its trips to the inner Solar System. Comet Halley is actually responsible for two known meteor showers, the other known as the Eta Aquarids and visible every May. An Orionids image featured on APOD one year ago today from the same location shows the same car. Next month, the Leonids Meteor Shower from Comet Tempel-Tuttle should also result in some bright meteor streaks. via NASA https://ift.tt/2JnZ0Sx

Someone Has Stopped Drinking The SLS Koolaid - For A Moment

SLS contractor gets real, says program needs to focus on "affordability", Ars Technica

"We here inside the program tend not to think about the need to advocate," Precourt said. "There are a lot of people with other ideas about how we should do this mission, so I think it's incumbent on us. It's not too early to be thinking about the transition from development to production. And that means a totally different management philosophy and cost structure for all of us." Precourt said contractors should consider a future in which NASA's present multibillion expenditures on rocket development costs need to be cut in half in order for the SLS vehicle to have a robust future. "All of us need to be thinking about [how] our annual budget for this will not be what it is in development," he said. "That's a very serious problem that we have to look forward to, and to try to rectify, so that we are sustainable." If the other speakers had thoughts about Precourt's comments, they did not share them during the ensuing discussion."

Airglow Borealis


The best known asterism in northern skies hangs over the Canadian Rockies in this mountain and night skyscape taken last week from Banff National Park. But most remarkable is the amazing greenish airglow. With airglow visible to the eye, but not in color, the scene was captured in two exposures with a single camera, one exposure made while tracking the stars and one fixed to a tripod. Airglow emission is predominately from atmospheric oxygen atoms at extremely low densities. Commonly recorded in color by sensitive digital cameras the eerie, diffuse light is seen here in waves across the northern night. Originating at an altitude similar to aurorae, the luminous airglow is due to chemiluminescence, the production of light through chemical excitation and radiative decay. Energy for the chemical excitation is provided during daytime by the Sun's extreme ultraviolet radiation. Unlike aurorae which are limited to high latitudes, airglow can be found around the globe. via NASA https://ift.tt/2Rko3Jg

IC 59 and IC 63 in Cassiopeia


These bright rims and flowing shapes look ghostly on a cosmic scale. A telescopic view toward the constellation Cassiopeia, the colorful (zoomable) skyscape features the swept-back, comet-shaped clouds IC 59 (left) and IC 63. About 600 light-years distant, the clouds aren't actually ghosts, but they are slowly disappearing under the influence of energetic radiation from hot,luminous star gamma Cas. Gamma Cas is physically located only 3 to 4 light-years from the nebulae, just off the top right edge of the frame. Slightly closer to gamma Cas, IC 63 is dominated by red H-alpha light emitted as hydrogen atoms ionized by the star's ultraviolet radiation recombine with electrons. Farther from the star, IC 59 shows proportionally less H-alpha emission but more of the characteristic blue tint of dust reflected star light. The field of view spans about 1 degree or 10 light-years at the estimated distance of gamma Cas and friends. via NASA https://ift.tt/2yAbkLj

Hyperion: Largest Known Galaxy Proto Supercluster


How did galaxies form in the early universe? To help find out, astronomers surveyed a patch of dark night sky with the Very Large Telescope array in Chile to find and count galaxies that formed when our universe was very young. Analysis of the distribution of some distant galaxies (redshifts near 2.5) found an enormous conglomeration of galaxies that spanned 300 million light years and contained about 5,000 times the mass of our Milky Way Galaxy. Dubbed Hyperion, it is currently the largest and most massive proto-supercluster yet discovered in the early universe. A proto-supercluster is a group of young galaxies that is gravitationally collapsing to create a supercluster, which itself a group of several galaxy clusters, which itself is a group of hundreds of galaxies, which itself is a group of billions of stars. In the featured visualization, massive galaxies are depicted in white, while regions containing a large amount of smaller galaxies are shaded blue.

Making Space Policy That Does Not Get Erased

NASA's recent woes took root with loss of space shuttle program, Houston Chronicle

"The decision to end the shuttle program came in 2004 as President George W. Bush's administration shifted its focus to frontiers beyond Earth's orbit. But with too few coins to divvy up amongst its many projects and a lack of political direction, the history-making agency instead has been forced to change course virtually every four years as political winds change. "NASA's budget and policy seem to be based on Twitter," said Keith Cowing, editor of NASA Watch, a website devoted to space news. "It's like, 'How can I come up with something in 280 characters?' We can't think long term. We can't think multi-administrations." That leaves space agency leaders wondering what will happen after the 2020 election. President Donald Trump has pushed to bolster human exploration -- with an eye toward the moon and then onto Mars -- but what happens if he isn't re-elected is anyone's guess. Policy fluctuations "can be difficult to weather," Mark Geyer, director of NASA's Johnson Space Center in Houston, previously told the Houston Chronicle. "It can cause fluctuations in the space program and that's hard if you're trying to move the country forward. But that's life, so you need to develop strategies to navigate that."

Halo of the Cat s Eye


Not a Falcon 9 rocket launch after sunset, the Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae in the sky. Its haunting symmetries are seen in the very central region of this composited picture, processed to reveal an enormous but extremely faint halo of gaseous material, over three light-years across. Made with data from ground- and space-based telescopes it shows the extended emission which surrounds the brighter, familiar planetary nebula. Planetary nebulae have long been appreciated as a final phase in the life of a sun-like star. But only more recently have some planetaries been found to have halos like this one, likely formed of material shrugged off during earlier active episodes in the star's evolution. While the planetary nebula phase is thought to last for around 10,000 years, astronomers estimate the outer filamentary portions of this halo to be 50,000 to 90,000 years old. via NASA https://ift.tt/2J867hR

Trump's NASA Administrator: 'No Reason' to Dismiss U.N. Climate Report, The Atlantic

"Koren: The United Nations recently released a troubling new report on climate change that outlined some of the devastating effects the planet should expect to see in the coming years. You've said before that you believe rising temperatures can be attributed to human activity. But many of your fellow Republicans in Congress and the White House dismissed the news. Where do you stand on the report?

Bridenstine: I have no reason to dismiss the report at all. nasa is one agency on the planet that does more to inform the world on how the climate is changing than any other agency, and we're going to continue to do that.

Koren: Do you see part of your role as administrator of nasa to discuss this with your fellow Republicans?

Bridenstine: My role is to deliver dispassionate science and allow policy makers to have these debates about it. Look, if I start engaging in what to do about the science that we receive, then it politicizes what nasa is all about, and we don't want to do that. All we're going to do is study the planet and make sure that all of that data and all of that science is made available to the public."

We have plans for at least three launches (before the next manned mission due in early December) from the Kourou space site, the launch of an unmanned spacecraft and of an unmanned spacecraft Progress. The confirmations will be more than enough to put the next crew in space," Krikalyov said."

Cherenkov Telescope at Sunset


On October 10, a new telescope reflected the light of the setting Sun. With dark horizon above and sunset colors below, its segmented mirror inverts an image of the beautiful evening sky in this snapshot from the Roque del Los Muchachos Observatory on the Canary Island of La Palma. The mirror segments cover a 23 meter diameter and are mounted in the open structure of the Large Scale Telescope 1, inaugurated as the first component of the Cherenkov Telescope Array (CTA). Most ground-based telescopes are hindered by the atmosphere that blurs, scatters, and absorbs light. But cherenkov telescopes are designed to detect very high energy gamma rays and actually require the atmosphere to operate. As the gamma rays impact the upper atmosphere they produce air showers of high-energy particles. A large, fast camera at the common focus images the brief flashes of optical light, called Cherenkov light, created by the air shower particles. The flashes reveal the incoming gamma ray timing, direction, and energy. Ultimately more than 100 Cherenkov telescopes are planned for the CTA at locations in both northern and southern hemispheres on planet Earth. via NASA https://ift.tt/2AggvBy

NASA Wallops Plays Games With The News Media Once Again

Keith's note: Great commercial space news. RocketLab is coming to NASA Wallops in Virginia to do commercial space launches. You'd think that all parties involved would want as much media present as possible - especially Virginia-based space media (like NASAWatch). Guess again. I first learned about this event, held on a NASA facility, staffed by NASA personnel, announced after it was underway on social media and broadcast on a NASA TV channel when I saw mention of it on Twitter. NASA Wallops PAO sent me nothing in advance. I caught the tail end of the webcast and discovered that there was also a phone bridge for media who are offsite to dial in to ask questions. No one at NASA Wallops PAO told me about that either. This is not the first time Wallops PAO has played this sort of games with me. I have sent an email to NASA PAO and Wallops personnel asking why NASAWatch was excluded from the advance notice and access provided to other news media. Until/unless I get a response (normally I get no response from Wallops) I am torn with ascribing this to incompetence - or spite- on Wallops' part given that this happens to me with some regularity.

Although I had no advance notice of this event, this is the question that popped into my head for RocketLab: "You are going to be doing a lot of launches at Wallops - and they do a lot of suborbital launches for student projects. Is your company looking to work with NASA and M.A.R.S. to provide additional opportunities for students and interns in Virginia to learn about space?".

M15: Dense Globular Star Cluster


Messier 15 is an immense swarm of over 100,000 stars. A 13 billion year old relic of the early formative years of our galaxy it's one of about 170 globular star clusters that still roam the halo of the Milky Way. Centered in this sharp telescopic view, M15 lies about 35,000 light years away toward the constellation Pegasus, well beyond the spiky foreground stars. Its diameter is about 200 light-years. But more than half its stars are packed into the central 10 light-years or so, one of the densest concentrations of stars known. Hubble-based measurements of the increasing velocities of M15's central stars are evidence that a massive black hole resides at the center of dense globular cluster M15. via NASA https://ift.tt/2P6fu72

Jupiter in Ultraviolet from Hubble


Jupiter looks a bit different in ultraviolet light. To better interpret Jupiter's cloud motions and to help NASA's robotic Juno spacecraft understand the planetary context of the small fields that it sees, the Hubble Space Telescope is being directed to regularly image the entire Jovian giant. The colors of Jupiter being monitored go beyond the normal human visual range to include both ultraviolet and infrared light. Featured from 2017, Jupiter appears different in near ultraviolet light, partly because the amount of sunlight reflected back is distinct, giving differing cloud heights and latitudes discrepant brightnesses. In the near UV, Jupiter's poles appear relatively dark, as does its Great Red Spot and a smaller (optically) white oval to the right. The String of Pearl storms farther to the right, however, are brightest in near ultraviolet, and so here appear (false-color) pink. Jupiter's largest moon Ganymede appears on the upper left. Juno continues on its looping 53-day orbits around Jupiter, while Earth-orbiting Hubble is now recovering from the loss of a stabilizing gyroscope. via NASA https://ift.tt/2OpUXec

NASA MSFC Employee Tries To Make Serkan Golge's Past Disappear

Keith's note: You all may be familiar with Serkan Golge, a NASA JSC employee who has been imprisoned in Turkey for bogus reasons for a long time. A NASAWatch reader noticed that someone at NASA is using the agency's Internet access to make changes to Golge's Wikipedia page - apparently in an effort to diminish his role at NASA. Golge was a full-time contractor with an office next to the MCC. But if you look at the edits it would seem that someone who wanted to minimize his role changed his page to say "working on projects." instead. Have a look at the before and after edits here. And another one here.
