UAE to raise private money to help refurbish Baikonur launchpad

8:39 am

The United Arab Emirates (UAE) has struck a deal with both Russia and Kazakhstan to jointly work together to upgrade the oldest Soyuz launchpad at Baikonur, the one used to put Yuri Gagarin into orbit in 1961.

The most interesting aspect of the deal is its private investment component:

The modernisation of the spaceport involves reconstructing the site to allow for more launches, including commercial and human space flights to the International Space Station.

As part of the agreement, all three parties will bring investors forward to contribute towards the upgrade.

“The UAE space agency is not investing or facilitating as the government. We’re looking for private partners within the UAE to partake. There’s a lot of interest,” Mr Al Qasim said.

This suggests that in exchange for providing private capital, the UAE will obtain launching rights at Baikonur, available for its own privately-built rockets. None yet exist, but it is clear the UAE government is encouraging such activity.

History Unplugged – The Age of Discovery 2.0: Episode 5

4:21 pm

Episode five of the six part series, The Age of Discovery 2.0, from the podcast, History Unplugged, is now available here.

On this episode Scott Rank interviews Rand Simberg. From the show summary:

The history of exploration and establishment of new lands, science and technologies has always entailed risk to the health and lives of the explorers. Yet, when it comes to exploring and developing the high frontier of space, the harshest frontier ever, the highest value is apparently not the accomplishment of those goals, but of minimizing, if not eliminating, the possibility of injury or death of the humans carrying them out.

To talk about the need for accepting risk in the name of discovery – whether during Magellan’s voyage in which 90 percent of the crew died or in the colonization of Mars – is aerospace engineer and science writer Rand Simberg, author of Safe Is Not An Option: Overcoming The Futile Obsession With Getting Everyone Back Alive That Is Killing Our Expansion Into Space.

For decades since the end of Apollo, human spaceflight has been very expensive and relatively rare (about 500 people total, with a death rate of about 4%), largely because of this risk aversion on the part of the federal government and culture. From the Space Shuttle, to the International Space Station, the new commercial crew program to deliver astronauts to it, and the regulatory approach for commercial spaceflight providers, our attitude toward safety has been fundamentally irrational, expensive and even dangerous, while generating minimal accomplishment for maximal cost.

Rand explains why this means that we must regulate passenger safety in the new commercial spaceflight industry with a lighter hand than many might instinctively prefer, that NASA must more carefully evaluate rewards from a planned mission to rationally determine how much should be spent to avoid the loss of participants, and that Congress must stop insisting that safety is the highest priority, for such insistence is an eloquent testament to how unimportant they and the nation consider the opening of this new frontier.

Definitely worth a listen, especially considering our society’s panic over COVID. Our society appears incapable of accepting any risk at all, even though risk cannot be avoided, and to do great things you must embrace it in some manner.

Hubble operations contract extended to 2026, even as engineers work to fix it

3:10 pm

NASA announced today that it has extended the contract for operating the Hubble Space Telescope through 2026, even as it also provided an update on the effort of engineers to bring all the telescope’s science instruments out of safe mode.

[T]he agency has awarded a sole source contract extension to the Association of Universities for Research in Astronomy (AURA) in Washington for continued Hubble science operations support at the Space Telescope Science Institute (STScI) in Baltimore, which AURA operates for NASA. The award extends Hubble’s science mission through June 30, 2026, and increases the value of the existing contract by about $215 million (for a total of about $2.4 billion).

…Currently, the spacecraft team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is investigating an issue involving missed synchronization messages that caused Hubble to suspend science observations Oct. 25. One of the instruments, the Advanced Camera for Surveys, resumed science observations Nov. 7, and continues to function as expected. All other instruments remain in safe mode.

During the week of Nov. 8, the Hubble team identified near-term changes that could be made to how the instruments monitor and respond to missed synchronization messages, as well as to how the payload computer monitors the instruments. This would allow science operations to continue even if several missed messages occur. The team has also continued analyzing the instrument flight software to verify that all possible solutions would be safe for the instruments.

In the next week, the team will begin to determine the order to recover the remaining instruments. The team expects it will take several weeks to complete the changes for the first instrument.

It appears that it is going to take some time to bring all the instruments back in line, considering that they are fixing the instruments one-by-one, in sequence, and that the first fix is taking weeks. Hopefully as they get each instrument back they will be able to move faster once they know what works.

Russia confirms and defends anti-satellite test

1:33 pm

Russia today confirmed that it had done the anti-satellite missile test earlier this week that destroyed one of its defunct satellites and produced a cloud of space junk.

Russia’s Ministry of Defence also issued a Russian-language statement defending the test. The minister-general of the army, Sergei Shoigu, said that the test was successful and that “the resulting fragments do not pose any threat to space activities,” according to a machine-generated translation to English.

The U.S. State Department said Monday that the test created a cloud of space debris made up of over 15,000 objects, calling it a threat to astronauts and cosmonauts, and space activities of all countries. The debris could pose a threat for years to come, experts have said. The space station’s crew had to shelter in their return ships on Monday when the debris cloud was first detected.

Russia’s space agency Roscosmos wrote on Twitter Monday that the space debris cloud “has moved away from the ISS orbit”, which is roughly 250 miles (400 km) above Earth. The space debris tracker LeoLabs estimates the debris cloud is at 273 to 323 miles (440 to 520 km) in altitude. However, “the station is in the green zone,” Roscosmos added.

The Russian claim that the debris at present poses no threat to ISS could very well be true. The trouble is that it appeared to have posed a threat initially, and will likely be a problem in the future. As a signatory of the Outer Space Treaty, Russia was required to avoid such a situation, and chose not to.

The article at the link notes similar tests by China (2007), the U.S. (2008), and India (2019). Of all these anti-satellite tests, only the U.S. targeted a satellite in an orbit so low that the debris posed no threat to operating satellites or manned spacecraft, and was also quickly pulled Earthward to burn up in the atmosphere. India chose a higher satellite whose debris posed less threat, but took longer to burn up and was initially of some concern.

China and Russia could have done the same thing. They did not, and their irresponsibility has badly worsened a problem that already was considered a serious concern.

Craters in the soft Martian northern lowland plains

Craters in the soft Martian northern lowland plains
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was a featured image today from the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The caption, written by Carol Weitz of the Planetary Science Institute in Arizona, focused on the wind patterns created within these craters.

These impact craters in the northern middle latitudes have interesting interiors: all of them have wind-blown (aeolian) ripples.

Outside of the craters and along the crater floors, the ripples are all oriented in the same direction. However, along the walls of some of the larger craters, the ripples are situated radially away from the center, indicating the winds moving inside the larger craters can be influenced by the topography of the crater wall.

Additionally, many of the larger craters have layered mesas along their floors that are likely sedimentary deposits laid down after the craters formed but prior to the development of the aeolian ripples.

I am further intrigued by the rimless nature of these craters, as well as the lack of significant rocky debris at their edges. They all look like the bolides that created them impacted into a relatively soft surface that, rather than break up into rocks and boulders, melted, flowed, and then quickly refroze into these depressions.

The location, as always, provides us a possible explanation.

They’re coming for you next: A freshman student from Exeter High School in New Hampshire is suing his school district and assistant principal for suspending him from one football game because he had stated his Catholic belief that there are only two genders in a text message exchange with another student.

The boy’s name is at this point being withheld, with the lawsuit being handled by his attorney, Ian Huyett of Cornerstone Action, a Christian advocacy group focused on New Hampshire issues.

The lawsuit alleges the student received a one-game suspension in September in violation of his constitutional right to free speech and the New Hampshire Bill of Rights because he expressed what the suit called his Catholic belief there are “only two genders,” male and female.

Branson sells another $300 million in Virgin Galactic stock

9:00 am

Capitalism in space: Richard Branson has sold another $300 million of his Virgin Galactic stock, reducing his share in the company to only 11.9%.

When Virgin Galactic went public, Branson sold off 49%, so that he was still the majority owner with 51% holdings. Since then, he has made more a billion dollars reducing his holdings to a point where today he is a very minor player in the company. Meanwhile, after that one suborbital passenger flight in July, that included Branson, the company has delayed further commercial suborbital flights until late next year while it overhauls WhiteKnightTwo and Unity.

Branson’s entire strategy with this company sure looks like a classic case of a pump-and-dump scheme. He pumps the company up for fifteen years, goes public, and then times his stock sales to maximize the value of the stock. And in the process he gets out before the company begins any commercial operations, when its viability will finally be demonstrated clearly.

FAA targets finalizing Starship environmental report by end of year

3:56 pm

The FAA today announced that it hopes to complete the permit process for SpaceX’s Starship operations at Boca Chica by the end of this year.

If you go to the link you will see a table that shows the agency’s overall plan. The table also suggests that extensions in the permitting process are also possible, though it appears the FAA is working now to avoid this.

I say excellent. I also say I will believe it when I see it. I want the FAA to show me my skepticism of this bureaucratic process is not justified. I want it to prove to me that there is no politics working in the background to slow the process.

Remember, after six months of work the FAA’s draft reassessment approved SpaceX’s Starship operations. To now delay or reject that approval will require a some heavy outside pressure, since the majority of the comments received by the the FAA during the comment period were favorable to the project.

Russian anti-sat test creates 1500 more pieces of space junk

3:40 pm

In what appears to be a test of Russia’s anti-satellite system dubbed Nudol, a defunct Russia satellite has been blasted into approximately 1,500 pieces by a missile launched from Russia.

Under normal circumstances, Kosmos 1408 would not have approached the International Space Station closely enough to pose a threat, however following the breakup, thousands of individual pieces of debris will have scattered into their own orbits. At least 1,500 pieces of debris from the satellite have already been identified by the United States Space Command. However, many smaller objects will have been generated, which will take much longer to identify. With high relative velocities, even a tiny fragment can cause significant damage should it collide with another spacecraft.

Owing to concerns about the debris cloud, the crew aboard the ISS were instructed to close hatches between the space station’s modules and take shelter aboard the Dragon and Soyuz capsules docked to the station.

According to the story at the link, ISS will cut through the expected debris cloud every orbit.

It is amazing that Russia would perform such a test on a satellite with an orbit that close to ISS’s, especially since there are many pieces of abandoned space junk in lower orbits so that their debris clouds would pose little problem, especially because their orbits would decay quickly.

This test is comparable to the Chinese anti-sat test in 2007, which caused a larger debris cloud that still poses a threat to ISS and other working satellites.

According to the Outer Space Treaty, a nation must control the objects it puts in space so that they pose no risk to others. Both the Russian and Chinese anti-sat tests prove these nations have no respect for the treaties they sign.
