A vent on Mars?

A vent on Mars?

Cool image time! In their exploration of the surface of Mars using Mars Reconnaissance Orbiter (MRO), scientists often image geological features that strongly resemble Earth features. Sometimes, if real, the resemblances are significant, as they indicate important geological activity on Mars that can tell us a lot about the conditions and environment there.

The image on the right, cropped and reduced in resolution to post here, is a good example of this. It was taken by MRO on June 14, 2018, just before the global dust storm obscured the planet’s middle latitudes for most of the summer, and was part of the monthly release of new images from the spacecraft. (If you click on the image you can see the full resolution picture.) The release website, which includes no caption, describes this feature as an “apparent vent,” a determination that certainly seems reasonable. The shadowed dark features suggest an abrupt oblong pit near the edge of a cliff, formed in the center of a collapsed sink. The tear-drop shape of the collapse sink and surrounding darkened areas also suggests that something is venting from it and then blowing away to the east and south, forming the darker stained ground. Some of the dark features to the southeast might also be smaller vents, releasing their own materials into the atmosphere.

The location also reinforces this suggestion, located on the southeast lava slopes of one of Mars’ larger volcanoes, Elysium Mons. This is also a region, dubbed Athabasca Valles, that some planetary scientists believe is one of the youngest lava flows on Mars.

Finally, it appears that the pit here has darkened considerably recently. MRO has taken images of this pit twice previously, in 2008 and 2010, and in both images the pit is much lighter in color, with its sandy dune-covered floor much easier to see. In the new image the floor is now very dark. This might be caused by shadows and the angle of the Sun, but I don’t believe so. It is also clear when comparing all three images that the surrounding area, including the flow to the southeast, has also darkened with time.

All this data suggests that the pit is venting something into the air, and it is settling on the ground to the southeast, blown there by the prevailing winds. Nor is this pit the only such feature in this region. Other images by MRO show a lot of similar dark splotches.

The problem is that this feature is not on Earth but on Mars. Determining what is being vented, and why, is therefore made more difficult. Based on Earth data you would assume this is some form of volcanic vent, releasing gases from below the surface. On Mars that assumption might not hold. We might instead be seeing the venting of any number of possible materials, such as underground water-ice, carrying with it other underground materials and thus darkening the surface.

We also can’t assume that the venting is occurring because of volcanic processes. On Mars the evidence so far gathered suggests that active volcanic activity ceased a very long time ago, even for this very young lava region. The venting is likely caused by something else, a fact that in itself is probably the most significant take-away from these images.

Something appears to be causing an active vent on the surface of Mars. Finding out the root cause of that venting is probably one of the more interesting questions facing researchers who study the Martian surface.

SpaceX turned down government money to build Falcon Heavy

Capitalism in space: In a presentation yesterday in Europe, one of SpaceX’s executives, Hans Koenigsmann, made it clear that SpaceX paid entirely for the development of Falcon Heavy, and in fact turned down an offer of government funding.

According to the SpaceX executive, the company was actually approached by “the government”, with the unknown agency or agencies stating – in Hans’ words – that they wanted to be a part of the rocket’s development. According to Hans, SpaceX responded in an extremely unorthodox fashion: “we said, ‘Nope! We just wanna build it, you can buy it when it’s ready and we’ll charge you for the service.’” He noted in the next sentence that funding was the primary lever on the table: “It’s a great position to do this, you gotta find the money, you gotta know people that have money and are willing to invest in your company, and [SpaceX has] been lucky enough to know some of those people.”

In other words, when given an opportunity to either rely on government funding or some other source of capital for a given R&D project, SpaceX – or at least Hans Koenigsmann, VP of Reliability – would apparently recommend the latter option in almost all cases. Again, without being prompted, he elaborated on his feelings about funding sources, culminating in a statement that is simply profound coming from an executive in the aerospace industry. The following quote is unabridged and straight from Hans himself:

“You need to [try to not] get money from the government, otherwise the government will tell you what to build and how to build it… they will tell you how to build this and that’s just not always – I mean for some things it’s the best to do, but in others it’s actually not.”

In other words, don’t let the government run your business. Use the government as an eventual customer, but build your product in a way that will not make them your only customer.

You can watch his entire presentation in the embedded video below the fold. Koenigsmann also noted that this Sunday’s first attempt to land a first stage at Vandenberg will likely produce a spectacular show for anyone who watches.

How one region’s space industry represents the world

bumper sticker

On October 2 I attended for the first time a monthly meeting of the Arizona Space Business Roundtable, an informal gathering put together by Stephen Fleming of the University of Arizona’s Strategic Business Initiatives and designed to allow the various space businesses of southern Arizona to network together as well as highlight what they are accomplishing to themselves and to others.

This particular meeting involved the presentation to the business community of a study that looked into the potential growth possibilities for space within the Tucson region. The study had been financed by the University of Arizona, several local venture capital companies, and the local county government, and had found that southern Arizona’s most likely source of space business in the near future would revolve around the need to track and monitor the large number of satellites expected to be launched in the coming decades. This would also involve substantial military work, as well as related space junk clean-up duties. The study also found that the southern Arizona space industry is well suited to provide much of the growing support services that future space missions, both governmental and private, will need. You can read more about the study’s results and the meeting at this Arizona Star article.

What struck me most about this gathering and the space industry of southern Arizona, however, is how much it resembles the regional space industries in numerous other places throughout the United States and the world. In fact, during a panel discussion after the presentation Fleming specifically asked the panelists — made up of several local companies (Vector, Worldview, Paragon) and two venture capital companies — what other regions in the U.S. posed the most competitive threat to southern Arizona. The panelists quickly listed Denver-Boulder, Silicon Valley in California, Huntsville in Alabama, the Space Coast in Florida, and New Mexico. They also made it clear that this list was not complete.

All of these regions are presently prospering and, more important, growing. All see a bright future in space, and all are aggressively competing to grab as large a market share in this future as they can. Even more significant, there appears to be more than enough business to go around. With numerous new countries pushing their own space efforts (China, India, UAE, Great Britain, Luxembourg, to name only a few), and both the American government as well as private companies attempting their own missions to the Moon and beyond, the possibilities appear endless. A lot of government money and investment capital is presently being poured into space, and numerous regions throughout the world are reaching for that money and the future profits it will bring.

And all of these regions are stock full of numerous independent and private companies and individuals, all pushing their own ideas about how space should be explored and conquered.

There are many aspects of the present charge to explore and settle the solar system that I do not like and believe will actually hamper and slow that exploration and settlement. Nonetheless, this charge is happening worldwide, and with amazing and increasing vigor. Even the worst proposals, such as NASA’s Gateway project, are going to eventually lead to new space technologies and capabilities that will sooner or later make it possible for the human race to routinely travel throughout the solar system.

It appears that the next two decades will lay the groundwork for the next few centuries of space exploration. And much of that groundwork will take place out of sight of the general public, with small companies located in regions like these. As with all great endeavors, the structure is that of a pyramid. At the top is the leader (such as SpaceX) that everyone watches and admires. Below it however is a vast subculture that provides the foundation for that leadership, even as it pushes upward to compete against it.

These are exciting times. I suggest if you love space you climb on the rocket now, before it picks up so much speed it will be beyond your reach.

NASA study says deep space will cause cancer and destroy stomachs

We’re all gonna die! A NASA study on rats using simulated space radiation suggests that long duration space missions beyond Earth orbit will cause cancer as well as significant harm to human intestines.

The study, published by cancer researchers at Georgetown University Medical Center, used mice to test exposure to heavy ion radiation, which mimics the galactic cosmic radiation found in deep space. If that sounds complicated, essentially researchers compared “space” radiation to X-ray radiation and found its effects to be much more dangerous.

After long exposures to a low dose of galactic radiation, mice had permanent damage to their gastrointestinal tracts and could no longer absorb nutrients in food. The mice also developed cancerous growths in their intestines — raising concerns that astronauts who venture far into space would face the same deadly health issues. “While short trips, like the times astronauts traveled to the moon, may not expose them to this level of damage, the real concern is lasting injury from a long trip,” said Kamal Datta, head of Georgetown’s NASA Specialized Center of Research, in a press release.

More here.

Must I point out the uncertainties and weaknesses of this study? They did the test on rats. They simulated the radiation. And it appears they simulated the radiation dosages assuming the spacecraft would have little or no shielding, an absurd approach.

Space is dangerous, but there is no reason to exaggerate the dangers wildly, unless you wish to generate fake reasons for additional funding, as NASA is prone to do.

Curiosity to switch computers in effort to restore operations

The Curiosity engineering team have decided to switch on-board computers in effort to figure out why the rover has been unable to store and send any data since September 15.

After reviewing several options, JPL engineers recommended that the rover switch from Side B to Side A, the computer the rover used initially after landing.

The rover continues to send limited engineering data stored in short-term memory when it connects to a relay orbiter. It is otherwise healthy and receiving commands. But whatever is preventing Curiosity from storing science data in long-term memory is also preventing the storage of the rover’s event records, a journal of all its actions that engineers need in order to make a diagnosis. The computer swap will allow data and event records to be stored on the Side-A computer.

Side A experienced hardware and software issues over five years ago on sol 200 of the mission, leaving the rover uncommandable and running down its battery. At that time, the team successfully switched to Side B. Engineers have since diagnosed and quarantined the part of Side A’s memory that was affected so that computer is again available to support the mission. [emphasis mine]

As indicated by the highlighted paragraph, the switch does carry some risk. Though they say they have isolated the problems with the A computer, they might be surprised when they turn it on.

Meanwhile, silence continues from Opportunity. After fourteen years of almost continuous rover operations on Mars, the United States have been roverless now for more than two weeks.

NASA signs agreement to work with SpaceIL’s privately built lunar rover

Capitalism in space: NASA, the Israeli space agency, and the private Israeli space company SpaceIL have signed a cooperative agreement to work together when SpaceIL’s privately built lunar rover is launched to the Moon in December.

NASA will contribute a laser retroreflector array to aid with ground tracking and Deep Space Network support to aid in mission communication. ISA and SpaceIL will share data with NASA from the SpaceIL lunar magnetometer installed aboard the spacecraft. The instrument, which was developed in collaboration with the Weizmann Institute of Science, will measure the magnetic field on and above the landing site. The data will be made publicly available through NASA’s Planetary Data System. In addition, NASA’s Lunar Reconnaissance Orbiter will attempt to take scientific measurements of the SpaceIL lander as it lands on the Moon.

This agreement is the first step in the transition from having the government build planetary probes to it becoming a customer, buying these probes from private companies that build them for profit.

A new Moon Race contest established

Led by Airbus, a number of private space companies and government agencies have established a new space contest dubbed “The Moon Race.”

The Moon Race competition is a global initiative founded by Airbus and international partners, aiming to boost the movement around Moon exploration and enable the demonstration of key technologies required for its sustainable exploration.

The Moon Race targets startups and SME’s worldwide and has the ambition to bring the winning teams to the lunar surface and provide solutions for the uprising lunar economy.

The competition is managed by “The Moon Race NPO gGmbH”, a not-for-profit organization based in Germany, whose goals are to manage The Moon Race competition and bring together the international space – and non-space – communities into one coordinated international initiative.

The partners listed so far are Airbus, Blue Origin, Vinci (an Italian space company), the European Space Agency, and Mexico’s space agency. Though their webpage is somewhat vague, it appears they are looking for new companies to join a program to compete for monetary prizes handed out year by year though 2023.

ISS’s international partners express interest in extending station’s life

While NASA has been considering the end of ISS, this week its international partners all expressed interest this week in extending its life beyond 2024.

During an Oct. 1 press conference at the 69th International Astronautical Congress (IAC) here, representatives of three ISS partner agencies said they were open to extending the station’s operations to 2028 or 2030 in order to maximize the investment they’ve made in the facility as a platform for research and preparation for exploration activities beyond Earth orbit.

Jan Woerner, director general of the European Space Agency, said the issue could come up at the next triennial meeting of the ministers of ESA’s member nations, scheduled for late 2019. “At the ministerial meeting next year, the ministerial council, I will propose to go on with ISS as well as the lunar Gateway,” he said. “I believe that we will go on.”

At a separate briefing Oct. 2, Woerner emphasized the use of the station as a research platform and encouraged greater commercial activities there. “I believe we should use the ISS as long as feasible,” he said. “I always thought 2024 was the end, but now I learned it is 2028, and yesterday I learned it’s 2030. So, I will try to convince the ESA member states that ESA should be a partner in the future.” However, he noted that ESA could defer the decision on a post-2024 ISS extension until its following ministerial meeting in 2022.

Hiroshi Yamakawa, president of the Japanese space agency JAXA, also emphasized the importance of making the most of the station. “I’d like to make the most of the present ISS,” he said. “We have to maximize the output of the ISS. Whenever the deadline comes to the ISS, we would like to participate in the ISS and maximize output.” He added, though, that there was not a pressing need for Japan to decide on an ISS extension. “JAXA is requesting budgets annually, so I think in that sense JAXA is quite flexible.”

Dmitry Loskutov, head of international relations at the Russian state space corporation Roscosmos, said Russia already expected an extension. “We anticipate the continued functioning until 2028 or 2030,” he said.

While I can see many benefits for extending ISS, leaving it as a wholly government-run operation will reduce its effectiveness while increasing its cost. I also suspect all these agencies are lobbying for funding. If they can get money for both ISS and Gateway, it will increase their footprint in space significantly.

Hayabusa-2’s third mini-lander successfully lands on Ryugu

MASCOT image of Ryugu surface

Update: The image at right, reduced to post here, was taken by MASCOT during its descent. You can see the spacecraft’s shadow in the upper right. If you click on the image you can see the full resolution version.

Original post: The German/French-build mini-lander MASCOT has been successfully deployed by Hayabusa-2 and has successfully landed on the asteroid Ryugu.

MASCOT came to rest on the surface approximately 20 minutes after the separation. Now, the team is analysing the data that MASCOT is sending to Earth to understand the events occurring on the asteroid Ryugu. The lander should now be on the asteroid’s surface, in the correct position thanks to its swing arm, and have started to conduct measurements independently. There are four instruments on board: a DLR camera and radiometer, an infrared spectrometer from the Institut d’Astrophysique Spatiale and a magnetometer from the TU Braunschweig. Once MASCOT has performed all planned measurements, it is expected to hop to another measuring location. This is the first time that scientists will receive data from different locations on an asteroid.

The spacecraft took 20 pictures during its descent, which were beamed to Hayabusa-2 where they are presently stored.

Celebrate Earthrise Day!

In only a little less than three months we will be celebrating the fiftieth anniversary of the December 1968 flight of Apollo 8 — first manned mission to another world. During that mission three humans spent 20 hours in orbit around the Moon, during which they read the first twelve verses of the Old Testament on Christmas Eve and became the first humans to witness an Earthrise and to photograph it.

To celebrate that achievement, a new website has been created, dubbed Celebrate Earthrise Day.

The website provides some great background material. You can listen to the astronaut’s Christmas telecast as well as see a recreation of the moment when the astronauts saw that Earthrise and Bill Anders took his famous color photo. The site also includes many photos from before, during, and after the mission, with many pictures coming from the personal family pictures of the astronauts. There is also audio of an 1988 Bill Anders’ interview, as well as a video of a fascinating presentation made by Bill and Valerie Anders, describing their life journey leading up to Apollo 8 and afterward.

Finally, and I think of most interest to my readers here, the site includes the audio of my introduction from the new audio edition of my book, Genesis: the Story of Apollo 8.

The site also includes the audio of one of the best radio interviews I have ever done, broadcast in 1998, on the subject of Apollo 8, our American culture, and the importance of each person choosing their path in life wisely. You can find that audio at the bottom of this webpage.

Check it all out. I think you will find it worth your while.

Deployment operations for Hayabusa-2’s MASCOT lander have begun

Engineers have begun the deployment sequence for Hayabusa-2’s MASCOT lander, with deployment planned for tomorrow.

Right now Hayabusa-2 is slowly moving closer to Ryugu, with live images appearing about once every half hour. More information about MASCOT can be found here. The lander can also hop like the MINERVA bouncers, but it can only do it once. Its battery life is about sixteen hours, so once it is deployed it will only operate on the surface for a short while.

Both the MINERVA and MASCOT mini-landers are mostly engineering tests for using small cubesat-sized spacecraft as probes. So far the MINERVA bouncers have been an unqualified success. Hopefully MASCOT will be as successfully.

Occator Crater on Ceres

Occator Crater

Cool image time! As Dawn’s long and successful mission to the asteroids Vesta and Ceres winds down, the spacecraft is taking a slew of spectacular close-up images of Ceres. The image on the right, cropped slightly to post here, is an oblique view of Occator Crater, home to the double bright spots that scientists now believe are caused by the upward seepage of a water-based brine from the interior.

The image was taken August 14, 2018 from a distance of 1149 miles. It clearly shows how the bright spots are depressions, not raised features. Additional images released this week of the floor of the crater capture a complex fracture network (seen here and here) with some fractures apparently quite deep.

All this suggests that the surface crust of Ceres is not very structurally strong, allowing a churning process that plows material up and down. The data also suggests that even on a small planetary body like Ceres the geological processes are going to be complex and often on-going, depending on material, energy, and the size of the body.

Three U.S. small space companies establish offices in Luxembourg

Capitalism in space: Three U.S. small space companies have now established offices in Luxembourg in order to take advantage of the financial backing that nation is willing to afford.

The government of Luxembourg announced Sept. 27 that CubeRover, Hydrosat and Made In Space will all establish facilities in the country, in many cases working with local universities and companies. The work those companies do in Luxembourg will range from development of robotic arms to small planetary rovers.

“The success of our development strategy for the space sector, including the recent launch of the Luxembourg Space Agency, is confirmed once more with the settlement in Luxembourg of three space companies that plan to employ up to 85 people in the Grand-Duchy by 2023,” said Étienne Schneider, deputy prime minister and minister of the economy of the Luxembourg government and the driving force for the country’s recent space initiatives.

The largest agreement, in terms of jobs created, goes to Made In Space. That company, best known for additive manufacturing work on the International Space Station, plans to work on a low-cost modular robotic arm for in-space applications, and will create up to 50 jobs in the country.

They did not mention what the terms are of Luxembourg’s financial support, but I suspect it is most helpful for these companies.

UAE astronaut flight to ISS tentatively scheduled for April

Russia has now tentatively scheduled the flight to ISS of the United Arab Emirates first astronaut.

The first astronaut from the United Arab Emirates (UAE) will fly to the International Space Station (ISS) on April 5, 2019, and will return to Earth on April 16, 2019, the ISS launch schedule, shared with Sputnik, has shown. According to the document, an astronaut will fly to the ISS on board the Russian Soyuz MS-12 spacecraft.

It has not been determined yet if Hazza Mansouri or Sultan Nayadi will take part in the mission. Both astronauts have qualified for it and have begun their training in Russia earlier in September.

Though the goal of this mission by the UAE government is to encourage a private space industry in their country, the mission remains wholly a government creature. What has not been released is how much UAE is paying the Russians for their flight.

Had the launch of the U.S. commercial crew spacecraft not been slowed by NASA and had been operational, either SpaceX or Boeing could have competed for this business. Expect them to do so in the future.

China launches smallsat

One of China’s claimed-to-be private companies, Expace, today launched a smallsat into orbit using the Kuaizhou-1A solid-fueld rocket. .

Exspace, like OneSpace and Ispace, is considered private by the Chinese. I find it interesting however that all these private companies have remarkably similar names, and all appear to be doing military work. Even if they get private financing from Chinese investors and their management is formed independent of the government, we should not be fooled. These are wholly owned and controlled by the Chinese government. They do nothing without its knowledge and support.

The leaders in the 2018 launch race:

26 China
16 SpaceX
8 Russia
7 ULA
6 Europe (Arianespace)

China has widened its lead over the U.S. in the national rankings, 26 to 24.

Roscosmos head meets with Chinese

The head of Russia’s Roscosmos space agency, Dmitry Rogozin, held meetings this week with China, discussing possible future space cooperation.

Russia can’t really afford to do much right now on its own, but it also wants to negotiate the best deal it can with anyone it works with in space. These discussions are therefore specifically designed to give Rogozin some negotiating leverage when he meets with NASA’s head Jim Bridenstine on October 10.

New images from Hayabusa-2’s mini-bouncers

Three press releases from the Hayabusa-2 science team last night provide new images from the spacecraft’s MINERVA bouncers, presently on the surface of Ryugu, as well as new high resolution images from Hayabusa-2 during its recent close-in maneuvers.

The images from the first story also includes a ten second movie showing a very rocky surface with the sun moving across the sky. The last link shows the primary landing site candidate with two backup sites.

All told, these images suggest that Ryugu is nothing more than a rubble pile stuck together. If it was heading to Earth, it might be difficult to deflect it, as it might break apart caused by any stress.

Next Long March 5 launch delayed again?

There are indications in the Chinese press that suggest the next launch of China’s largest rocket, the Long March 5, will be delayed from its present November launch into 2019.

An online report by People’s Liberation Army Daily, a military newspaper, reports Lin Xiqiang, deputy director of the China Manned Space Engineering Office (CMSEO), as saying at a press conference in Beijing on Wednesday that the Long March 5B will not make its planned test launch in the first half of 2019.

“Due to the failure of the launch of the Long March 5 remote launch vehicle, the first flight of the Long March 5B carrier rocket will be postponed. The specific implementation time needs to be clarified after coordination with relevant departments,” Xiqiang said.

The November launch was to put up a test communications satellite. Should it slip into 2019, this would likely also cause delays in the launch of China’s first lunar sample return mission, Chang’e-5 (originally scheduled for 2017), the launch of China’s first Mars planetary mission in 2020, and finally the launch of the first module of China’s space station, also set for 2020.

All this once again indicates that the problems with Long March 5 were very serious, and might not yet have been addressed, even with a redesign of its engines.

ULA picks Blue Origin rocket engine for Vulcan first stage

Capitalism in space: ULA has chosen Blue Origin’s BE-4 rocket engine to power the first stage of its next generation rocket, which they are now calling Vulcan-Centaur.

Two BE-4 engines will be used to power the Vulcan first stage. The press release does not mention anything about how they plan to recover these first stages. Earlier announcements had said that they would separate from the rocket stage and parachute down to be capture before hitting the ground.

Local Texas city council votes to keep spaceport

The Midland, Texas city council today voted to renew its contract with the company managing its spaceport there.

The council voted 6-1 to renew its contract with SilverWing Enterprises, an aerospace consulting company that manages Midland’s spaceport license. The one vote came from Spencer Robnett, who has been public with his belief that the spaceport needs to be shut down.

“Yeah I don’t think it would ever have a chance in Midland,” Robnett said. “I do think the space business and space technology and aerospace sector is evolving. There’s a lot of money being invested in it by billionaires, Bezos, Musk, and Branson. Unfortunately we don’t have a billionaire in Midland chasing aerospace investment. We’ve got a small economic development corporation that takes direction from the city council.”

Robnett might have a point. Midland’s spaceport had been the base of operations for XCOR’s Lynx, and with XCOR bankrupt and gone there doesn’t seem to be a lot of interest by anyone else in flying any rockets from there. Part of their problem is their location, which is far from the coast and would likely limit the launch options in order to avoid populated areas.

The question has to be: What does Midland offer to rocket companies that other spaceports don’t? Until they can provide an answer to that question, the money the council is spending on this spaceport is probably going to waste.

NASA extends Chandra telescope operation to 2024

NASA has extended its contract with the Smithsonian Astrophysical Observatory in Massachusetts to run the Chandra X-ray Observatory through 2024.

In many ways the longevity of both Hubble and Chandra as well as other space telescopes has demonstrated the robustness of much in-space engineering these days. It suggests that when we finally begin building manned interplanetary spaceships we should have confidence they will operate reliably for long periods.

SpaceX gets contract to launch private lunar rover missions

Capitalism in space: SpaceX has won a contract for two launches of lunar rovers built by a private Japanese company.

Tokyo-based lunar-exploration startup Ispace has signed up for launches on SpaceX’s Falcon 9 rocket in 2020 and 2021. The first will carry a lunar lander into orbit around the moon, and the second aims to put one on the moon’s surface so it can deploy a pair of rovers, Ispace said Wednesday. “We share the vision with SpaceX of enabling humans to live in space, so we’re very glad they will join us in this first step of our journey,” Ispace Chief Executive Officer Takeshi Hakamada said in a statement.

SpaceX already has a contract for another private lunar rover, built by the Israeli company SpaceIL, that is set to launch as a secondary payload in December.

Both companies are former competitors in the Google Lunar X-Prize competition. Based on these contracts, as well as the pending launch of Moon Express’s private lunar rover on a Rocket Lab Electron rocket, it appears that private commercial planetary missions are about to become routine.

Mars Reconnaissance Orbiter spots Opportunity through dust

Mars Reconnaissance Orbiter has taken a picture through the fading Martian dust storm that spots Opportunity about halfway down Perseverance Valley in the rim of Endeavour Crater.

Engineers have been increasing the number of times per day they are attempting to communicate with the rover, so far all to no avail. The picture thus only really tells us that the storm is lifting and that MRO’s high resolution camera is operating normally after three months of limited picture taking because of the dust storm.

Australian agency pushes Australia to join NASA Gateway project

The new colonial movement: An Australian government agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), has put forth a space roadmap for that nation that includes a push for them to participate in NASA’s lunar orbiting Gateway project.

“And when you look at a moon base, the support systems of oxygen, water, food – and the general support systems around it – is something that nobody has ever done before,” he said. “When we looked around Australia, these are areas where Australia has as much skill as anyone else. Things like dry farming capabilities, remote mining capability, the fact that CSIRO perfected the titanium dust that you can 3-D print from … there are a whole range of things where we can potentially contribute.” It is an interesting fact that Australia has exceptional expertise in 3D printing titanium. This is even more interesting when you consider that on the moon – according to Dave Williams – there is an oxide that is very similar to titanium that could be reduced to a titanium dust, with oxygen as a by-product.

“Realistically, NASA will lead the whole thing. But they will be looking for partners, and the idea will be to identify which niche areas Australia should try to push its industry into, and try to get support for and to make it work,” he said.

Essentially, they are proposing that Australia get in on the Gateway boondoggle by focusing on and then offering to provide peripheral support services.

Much of this is bureaucratic twaddle, not to be taken too seriously. At the same time, it does outline for Australia areas where there are needs, and where their private space companies could make money.

Has Aerojet Rocketdyne lost engine race with Blue Origin?

Aerojet Rocketdyne financial documents suggest that it has given up the bidding competition with Blue Origin to supply a rocket engine for ULA’s Vulcan rocket.

The latest financial release from aerospace manufacturer Aerojet Rocketdyne reveals that the company spent none of its own money on development of the AR1 rocket engine this spring. Moreover, the quarterly 10-Q filing that covers financial data through June 30, 2018 indicates that Aerojet may permanently stop funding the engine with its own money altogether—a sign the company has no immediate customers.

Although Aerojet will continue to receive some funding from the US military through next year to develop its large, new rocket engine, this money won’t be enough to bring it to completion. Instead of having a flight-ready engine for use by the end of 2019, the filing indicates that Aerojet now intends to have just a single prototype completed within the time frame.

Essentially this means ULA will have no choice but to pick Blue Origin’s engine, unless the Air Force pulls its weight and demands it take Aerojet rocketdyne, even if that means a significant delay before Vulcan can launch.

Dust storms spotted on Titan

Scientists reviewing Cassini data have identified dust storms for the first time of Saturn’s moon Titan.

When Rodriguez and his team first spotted three unusual equatorial brightenings in infrared images taken by Cassini around the moon’s 2009 northern equinox, they thought they might be the same kind of methane clouds; however, an investigation revealed they were something completely different. “From what we know about cloud formation on Titan, we can say that such methane clouds in this area and in this time of the year are not physically possible,” said Rodriguez. “The convective methane clouds that can develop in this area and during this period of time would contain huge droplets and must be at a very high altitude — much higher than the 6 miles (10 kilometers) that modeling tells us the new features are located.”

The researchers were also able to rule out that the features were actually on the surface of Titan in the form of frozen methane rain or icy lavas. Such surface spots would have a different chemical signature and would remain visible for much longer than the bright features in this study, which were visible for only 11 hours to five weeks.

In addition, modeling showed that the features must be atmospheric but still close to the surface — most likely forming a very thin layer of tiny solid organic particles. Since they were located right over the dune fields around Titan’s equator, the only remaining explanation was that the spots were actually clouds of dust raised from the dunes.

Obviously there are large uncertainties here. Nonetheless, the conclusion is a reasonable one, as it is expected that such dust storms would occur on Titan.

Greenhouse in Antarctica survives winter for 1st time

A greenhouse in Antarctica that is partly maintained remotely from Germany has survived through the polar winter for the first time.

Regularly withstanding temperatures below minus 40 degrees Fahrenheit (minus 40 degrees Celsius), the greenhouse provided herbs, lettuce and other vegetables to 10 people who were riding out the winter in the remote station, called the Alfred Wegener Institute’s Neumayer Station III. It’s the first time the greenhouse operated through the winter. “After more than half a year of operation in Antarctica, the self-sufficient greenhouse concept appears to be effective for climatically demanding regions on Earth, as well as for future manned missions to the moon and Mars,” DLR officials said in the statement.

“The harvests are now so plentiful that some of it does not always make it straight to the table, and we now have the luxury of spreading out our consumption of some refrigerated lettuce and herbs over several days,” Paul Zabel, a DLR researcher who works with EDEN ISS, said in the statement. “The overwintering team members are always looking forward to their next fresh meal.”

From a space exploration perspective, the most interesting aspect of this story is that, when the weather was too hostile for its Antarctic maintainer to reach it, the greenhouse was then maintained remotely from Germany, for up to three consecutive days. Clearly hands-on maintenance is necessary for such a facility, but to design it so that remote maintenance can occur is a technical capability that space-colonists are definitely going to want to have.
