Haley Reinhart & Casey Abrams – Time of the Season

6:01 pm

An evening pause: Hat tip Dan Morris.

Readers! I am in need of evening pause suggestions! If you’ve seen something you think would work, say so in the comments, without providing a link. I will email you. For those interested in participating in making this webpage fun, here are my guidelines for suggesting evening pauses:

1. The subject line should say “evening pause.”
2. Don’t send more than three in any email. I prefer however if you send them one email at a time.
3. Variety! Don’t send me two or three or five from the same artist. I can only use one. Pick your favorite and send that.
4. Live performance preferred.
5. Quirky technology, humor, and short entertaining films also work.
6. Search BtB first to make sure your suggestion hasn’t already been posted.
7. I might not respond immediately, as I schedule these in a bunch.

Volcanic vent on Mars

2:43 pm

Overview of Arsia Mons pits

To understand today’s cool image we really should start from a distance and zoom in. The overview map to the right focuses in on the two southernmost giant volcanoes in the string of three that sit to the east of Mars’ biggest volcano, Olympus Mons, and to the west of the planet’s biggest canyon, Valles Marineris.

The black dots mark the locations of the many high resolution photos taken by Mars Reconnaissance Orbiter that I have featured previously on Behind the Black. Many are isolated openings with no related geological features. Others appear to be skylights into a more extensive lava tube, hinted at by either a continuing surface depression or a series of similar skylights.

The white dot marks the location of today’s cool image, about 350 miles south of Arsia Mons’ caldera.

Today’s blacklisted American: David Horowitz Freedom Center banned from Breakers hotel in Florida

The new dark age of silencing: The Breakers hotel in Palm Beach, Florida has banned the conservative David Horowitz Freedom Center (DHFC) from holding an event there, despite the fact that it has allowed such an event every year without problems for the past twenty years.

The reason?

“After a 20-year relationship with The Breakers resort, the Freedom Center was informed that we would no longer be allowed to have our annual Restoration Weekend event at the resort due to the Center being too controversial,” DHFC President Michael Finch told The Epoch Times. [emphasis mine]

The hotel claims the ban isn’t because of politics, but because the “logistical and operational requirements” of holding the annual event had become more complex. While the hotel was not specific, its statement strongly implied that the increased cost of security against leftist threats of violence caused it to cancel the contract.

In other words, the hotel endorses the heckler’s veto. Threaten violence against someone who disagrees with you and The Breakers will bend over backwards to silence that speaker for you.

I would say that anyone planning to visit Palm Beach should celebrate The Breakers new policy of cowardice and find some other hotel to stay at. It certainly seems that this hotel really isn’t interested in protecting conservatives from violence. It would rather ban them from existence.

UAE Al-Amal Mars orbiter finds surprising variations in Mars atmosphere

10:32 am

Oxygen variations in Martian atmosphere
Click for full graphic.

The United Arab Emirates Al-Amal (“hope” in English) Mars orbiter has discovered unexpected variations of oxygen and carbon monoxide in the Martian atmosphere.

The EMM team had expected to observe a relatively uniform emission from oxygen at 130.4 nm across the planet and yet here we are, faced with unpredicted variations of 50% or more in the brightness.

The image to the right, cropped and reduced to post here, shows the variations in oxygen on Mars’s dayside. Though the map does not indicate the geography below, the concentration of oxygen in the northern latitudes appears to correspond to the planet’s northern lowland plains. In fact, the variations should not have been a surprise, since the surface of Mars has such a stark dichotomy between its northern and southern hemispheres.

Ingenuity’s 16th Martian flight is now scheduled for November 18

9:27 am

According to an update today from the Ingenuity science team, Ingenuity’s sixteenth flight on Mars is scheduled for no earlier than November 18th, and will be a relatively short hop of about 100+ meters to the north, compared to previous flights.

It appears the roughness of the terrain on this flight can cause an accumulating error in its flight software. Because the landing area is also rough, they want to bring the helicopter down sooner to make sure it lands close to where it should.

The present plan is to hop north to return to the location of Ingenuity’s first flight, at Wright Brothers Field. Along the way they will also consider installing an update in the flight software to improve the helicopter’s capabilities.

NASA expected to finally certify Rocket Lab’s Virginia launchpad by end of year

9:15 am

It appears that after more than a year of delays, the NASA bureaucracy might finally approve launches at Rocket Lab’s new spaceport at Wallops Island, Virginia by the end of the year.

The article at the link is mostly about Rocket Lab’s planned acquisition of another company that builds satellite deployment systems. However, its real story was in the last paragraph:

[T]he company is still waiting for NASA to complete certification of an autonomous flight termination system the company needs to launch from Wallops Island, Virginia. Delays in NASA’s certification of that system has, in turn, delayed the use of Launch Complex 2 there for Electron missions. “The current expectation is that it could be done as early as the end of the year,” [Adam Spice, Rocket Lab’s chief financial officer] said of that certification, “which would allow us to commence flight operations out of LC-2 and Wallops in the first half of 2022.”

The company got FAA approval for launches more than a year ago, and had hoped to launch shortly thereafter. NASA however has blocked that launch, refusing for more than a year to approve the flight termination system Rocket Lab uses to destroy rockets should something go wrong just after launch.

The delay is baffling. Rocket Lab has successfully proven that its system works in that it has used it several times to safely abort launches in New Zealand. This success apparently has not been good enough for NASA’s bureaucrats, and the result is that Rocket Lab’s ability to launch rockets has been seriously hampered in ’21.

Europe joins U.S. in condemning Russian anti-satellite test

8:57 am

Europe’s top space policy chief today joined the U.S. in strongly condemning the Russian anti-satellite test that produced a cloud of several thousand pieces of orbiting space junk.

European Commissioner for Internal Market Thierry Breton condemned Russia’s anti-satellite missile system test, which led to the destruction of a satellite in low orbit.

“As European Union (EU) Commissioner in charge of EU Space policy and in particular of Galileo & Copernicus, I join the strongest condemnations expressed against the test conducted by Russia on Monday November 15, which led to the destruction of a satellite in low orbit (COSMOS 1408),” Breton wrote on Twitter late on Tuesday.

The Russians continue to insist the debris poses no threat to ISS, but their own state-run press proves them wrong. This TASS report claims the debris is no threat because it orbits 40 to 60 kilometers (25 to 35 miles) above the station.

That the debris is presently orbiting above the station is exactly why it poses a threat. While mission controllers will periodically raise ISS’s orbit to counteract the loss of altitude due to friction from the very thin atmosphere at that elevation, the various orbits of the satellite debris will continue to fall. Eventually that entire cloud will be drop into ISS’s orbit.

It is likely that the debris spread over time will make it easy for controllers to shift ISS to avoid individual pieces, but the need to dodge will certainly increase with time, raising the odds that something will hit the ISS.

The test seems almost so stupid an act by Russia that one wonders if its purpose was to create a long term threat to ISS itself. At least one private U.S. company, Axiom, plans to attach its own modules to ISS and use it as a base for the next few years for commercial operations. Others want to use ISS as a hotel for private tourists.

The Russians meanwhile are planning to launch their own new station. If the Russians put it in an orbit safe from this debris cloud, this test will have thus conveniently damaged their main competitor in commercial space operations.

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.
