Virgin Orbit pauses operations; seeks funding

9:15 am

Virgin Orbit today paused all operations for at least a week, putting almost its entire staff on furlough as it seeks new financing.

Chief Executive Dan Hart told staff that the furlough would buy Virgin Orbit time to finalise a new investment plan, a source who attended the event told Reuters news agency. It was not clear how long the furlough would last, but Mr Hart said employees would be given more information by the middle of next week.

If Virgin Orbit dies, its death will be because a British government agency killed it. The company had planned on launching from Cornwall in the early fall of 2022, at the latest, and then do several other launches in 2022, all of which would have earned it revenue. Instead, the UK’s Civil Aviation Authority (CAA) delayed issuing the launch license until January 2023, about a half a year later, preventing Virgin Orbit from launching for that time and literally cutting it off from any ability to make money. The result was that it ran out of funds.

Obviously the launch failure that followed the CAA’s approval did not help. Nor did the company’s decision to rely on only one 747 to launch its satellites. Nonetheless, the fault of this company’s death can mostly be attributed to a government bureaucracy that failed in its job so badly that it destroyed a private company.

China’s Long March 11 rocket launches classified Earth observation satellite

9:06 am

China yesterday used its Long March 11 solid-fueled four-stage rocket to launch a classified Earth observation satellite into orbit.

The launch was from an interior spaceport, so the rocket’s lower stages crashed somewhere in China or Mongolia. No word on if they landed near habitable areas.

The 2023 launch race:

17 SpaceX
10 China
4 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise still leads China 18 to 10 in the national rankings, and the entire world combined 18 to 16. SpaceX alone is now tied with entire world, including the rest of the U.S., 17 to 17.

Pushback: Legal and public pressure forces California college to cancel plans to fire employees for not getting jab

12:21 pm

The board of trustees of San Diego Community College
The board of trustees of San Diego Community College

They’re coming for you next: The board of trustees of San Diego Community College in late February 2023 had been moving to fire a number of teachers and employees because they all refused for various medical and religious reasons to get COVID shots or boosters.

The policy was senseless in all ways. As Tracy Kiser, a pregnant black professor who was refusing the jab because of the risk it posed to her unborn child, noted in a February 21st op-ed:

“Last year, after a decline in enrollment, the San Diego Community College District dropped the COVID-19 vaccine requirement for students, but it has not been dropped for faculty and staff,” wrote Kiser, who also directs her school’s math center. [emphasis mine]

If the college’s trustees believe blindly that the jab prevents COVID (which it does not) and wants to protect its employees, why does it allow those employees to teach unjabbed students?

The board’s idiocy was further illustrated by Kiser’s description of this incident during one board meeting:

Geological evidence of past glacier found in Mars’ dry equatorial regions

11:04 am

Overview map

Scientists have uncovered geological evidence of a past glacier in westernmost end of the giant Martian canyon Valles Marineris, right at the point where it transitions into the complex chaos region dubbed Noctis Labyrinthus. The white dot on the map to the right indicates the location.

The surface feature identified as a “relict glacier” is one of many light-toned deposits (LTDs) found in the region. Typically, LTDs consist mainly of light-colored sulfate salts, but this deposit also shows many of the features of a glacier, including crevasse fields and moraine bands. The glacier is estimated to be 6 kilometers long and up to 4 kilometers wide, with a surface elevation ranging from +1.3 to +1.7 kilometers. This discovery suggests that Mars’ recent history may have been more watery than previously thought, which could have implications for understanding the planet’s habitability.

“What we’ve found is not ice, but a salt deposit with the detailed morphologic features of a glacier. What we think happened here is that salt formed on top of a glacier while preserving the shape of the ice below, down to details like crevasse fields and moraine bands,” said Dr. Pascal Lee, a planetary scientist with the SETI Institute and the Mars Institute, and the lead author of the study. [emphasis mine]

You can read the paper here [pdf]. The research specifically suggests that near surface water ice in the dry equatorial regions of Mars could have been there much more recently that previously believed. It also suggests, by the rarity of this discovery, that there is likely almost no near surface ice in the equatorial regions, at present.

Firefly wins its second NASA contract to land payloads on the Moon

8:59 am

Capitalism in space: Firefly announced today that it has won a $112 million NASA contract to use its Blue Ghost lunar lander to bring three instruments to the Moon, one into orbit and two on the ground on the far side of the Moon.

Before landing on the Moon, the company’s Blue Ghost transfer vehicle will deploy the European Space Agency’s Lunar Pathfinder satellite into lunar orbit to provide communications for future spacecraft, robots, and human explorers. After touching down on the far side of the Moon, the Blue Ghost lunar lander will deliver and operate NASA’s S-Band User Terminal, ensuring uninterrupted communications for lunar exploration, and a research-focused payload that measures radio emissions to provide insight into the origins of the universe.

The NASA press release provides more details about the three payloads.

This is Firefly’s second NASA lunar lander contract. The first is scheduled to land in 2024 and deliver ten NASA science instruments to Mare Crisium, the large mare region in the eastern side of the Moon’s visible hemisphere. This second flight is tentatively scheduled to launch in 2026.

NASA agrees to Axiom’s third planned commercial passenger mission to ISS

8:45 am

NASA today announced that it has given Axiom the go-ahead for its third planned commercial passenger mission to ISS, now tentatively scheduled for November 2023.

Axiom Mission 3 (Ax-3) is expected to spend 14 days docked to the space station. A specific launch date is dependent on spacecraft traffic to the space station and in-orbit activity planning and constraints. NASA and Axiom Space mission planners will coordinate in-orbit activities for the private astronauts to conduct in coordination with space station crew members and flight controllers on the ground.

As NASA did in announcing its agreement to Axiom’s previous flight, the agency’s press release makes believe it “selected” Axiom for this flight, as if it had the power and right to do so. Hogwash. Axiom has purchased the flight from SpaceX, and wishes to rent space on ISS for two weeks for its customers. All NASA has done is agree to the deal, while also charging Axiom very large fees for that rental.

A Martian crater, ice, and dust devil tracks

A Martian crater, ice, and dust devil tracks
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on January 2, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It is once again a terrain sample image, taken not for any specific research but to fill a gap in the schedule so as to maintain the camera’s proper temperature.

What this picture shows is that even though Mars has a thin atmosphere that produces dust devils, the propagation of dust devils is not uniform across the red planet’s surface. In this picture there are a lot of devil tracks, going in many different directions. Yet few of the many cool images I post from MRO show this number of tracks. In many cases the ground might not be agreeable to leaving tracks, but that cannot be the entire explanation.

Today’s blacklisted American: Eventbrite routinely blacklists conservative events

1:52 pm

Eventbrite: hostile to freedom

They’re coming for you next: Eventbrite, an online “self-service ticketing platform”, has been routinely blacklisting conservative events, often cancelling already existing events or telling customers the event no longer exists, always for vague and often contradictory reasons.

What Eventbrite did to one Matt Walsh event is typical:

In late February, the website removed from its page for a [March 1st] Matt Walsh event on transgenderism sponsored by Young America’s Foundation at Stanford University. Organizers were forced to set up an alternative event page just before Walsh’s appearance. Not only did Eventbrite remove the page, “[h]undreds of registered attendees were surprised to receive emails from the company informing them that their tickets had been canceled,” YAF wrote in a Feb. 27 news release.

Though students at Stanford set fire to promotional flyers put up by YAF prior to the event, the event itself went off without incident.

The article at the first link above lists numerous other times Eventbrite cancelled conservative events without explanation, including several other Walsh university events, a screening of Dinesh D’Souza’s film 2000 Mules that documents fraud and election tampering in the 2020 election, a event in support of the U.S. military, and a Memorial Day event honoring veterans.

All of this blacklisting contradicts Eventbrite’s own mission statement:

Potential Artemis-3 landing site on the Moon

10:54 am

The landing zone for the Artemis-3 mission to the Moon

Overview map

The panorama above was released today by the Lunar Reconnaissance Orbiter (LRO) science team, and shows one of the candidate landing sites (arrow) where Starship could land as part of the Artemis-3 mission to the Moon.

The map of the south pole to the right, created from LRO images and annotated by me, gives the context. The yellow lines indicate the approximate area covered by the panorama. The terrain here is rugged, to put it mildly. As the science team notes,

Imagine the view from the summit; it rises more than 5000 meters (16,400 feet) above its base. Off in the distance, you could see a 3500 meter (11,480 feet) tall cliff. One could argue that the sheer grandeur of this region makes it a prime candidate. But then again, a landing here might be too exciting?

That 11,480-foot-high cliff is the crater wall to the right of the arrow. Make sure you go to the link to view the original image. This will be a spectacular place to visit. Whether the astronauts however will be able to find out anything about ice in the shadowed crater floor thousands of feet below them remains questionable.

Artemis-3 is presently scheduled for 2025 but no one should be surprised if it is delayed.

LeoLabs to establish radar facility in Argentina

9:41 am

LeoLabs, a private commercial company aiming to provide orbital tracking of all space objects as small as two centimeters, has announced plans to establish its seventh global radar facility in Argentina.

The S-band radar, scheduled to be completed by the end of the year, will be located on the archipelago of Tierra del Fuego. “The Southern Hemisphere has not been well covered for space safety and space domain awareness,” LeoLabs CEO Dan Ceperley told SpaceNews. “There are a lot of conjunctions close to the North Pole and the South Pole. This radar will make a very meaningful improvement in the tracking of those conjunctions.”

Currently, LeoLabs tracks objects in low-Earth orbit with phased array radars in Alaska, Australia, Portugal’s Azores archipelago, New Zealand, Texas and Costa Rica.

The company essentially competes with the Space Force in tracking object in orbit, and has raised more than $100 million in private investment capital to build its ground stations.

Space startups get their SVB assets back when Feds move in

9:34 am

Because of the decision of the federal government to guarantee all deposits at the failed Silcon Valley Bank (SVB), even those above the $250K limit set by the FDIC law, several space rocket startups are no longer threatened with failure, for now.

Astra for example is now seeking to move as quickly as it can its assets, equaling about 15% of the company, to other financial institutions.

I would expect this incident will cause every company to make sure their assets are distributed more widely, as a hedge against the failure of one bank.

Splats on Mars!

Splats on Mars
Click for original image.

Cool image time! The picture to the right, cropped and sharpened to post here, was taken on February 3, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a number of crater splats of varying sizes. If you look at the full image, you will find several even bigger splats to the north of the one in the picture to the right. You will also see many more similar-sized crater splats to the south.

I cannot provide any confident explanation about what caused these splats, other than to assume that most here are secondary impacts from ejecta thrown out by a larger impact somewhere nearby. I also assume all these small impacts occurred at the same time because they all appear to have hit the ground when it had the same thick liquid consistency, a condition that was probably temporary. Note for example how many of the other craters in the full image do not have this same splattered look.

The sad state of free speech in America illustrated by three top universities

1:03 pm

Cancelling the Bill of Rights

Events in the last two weeks at three of America’s top universities, Stanford, Cornell, and Yale, have illustrated starkly how many young Americans and their teachers now either support censorship and violence against dissenters, or are too cowardly to defend the rights of Americans when their free speech rights are attacked.

At the Stanford Law School a 5th Circuit Judge, Stuart Kyle Duncan, was shouted down and then lectured by a dean at the school for daring to have opinions she disagreed with. Stanford officials have issued a weak apology, but have done nothing concrete to discipline anyone for enforcing a heckler’s veto at the school.

At Cornell, the promise of university officials to punish students who participated in a protest that shouted down Ann Coulter has apparently been put aside once the heat died down.

Cornell University’s media team has not responded to multiple inquiries in the past months on possible punishments for the student activists. The College Fix also emailed communications director Rebecca Valli on March 6 and asked for an update on investigations into the students involved and what Cornell planned to do in the future to prevent similar problems.

The silence comes despite an initial strong statement from university leadership that criticized the Nov. 9 disruption.

Finally, officials at Yale Law School have attempted to fix things after being badly embarrassed by a similar violent protest in March 2022, when students shouted down Kristen Waggoner, the president of the non-profit law firm the Alliance Defending Freedom (ADF). » Read more

Chinese pseudo-commercial rocket industry gearing up to launch numerous times from interior spaceport

12:07 pm

China's spaceports

Even as China is presently building a commercial launch facility at its Wenchang spaceport on the coast, at least four of China’s pseudo-commercial rocket companies are gearing up to launch numerous times from the Jiuquan Satellite Launch Center in the interior of China.

The link above shows the launch sites being built at Jiuquan by pseudo-companies Landspace, Expace, CAS Space, and Space Pioneer. The map to the right illustrates what these interior launches will mean. Since none of these pseudo-companies will be vertically landing their first stages — at least not for several years — it means that numerous first stages will be coming down in many areas in China and Mongolia, most of which will be uncontrolled descents.

Eventually the Wenchang launch facility on the coast will become available, but based on past Chinese actions, do not expect these pseudo-companies to end their operations at Jiuquan at that time. All are controlled by the Chinese government, which has made it very clear it really doesn’t care if first stages crash near habitable areas.

Hubble looks at a nearby dwarf galaxy

9:38 am

A nearby dwarf galaxy
Click for original image.

Cool image time! The photo to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope as part of a continuing project to capture high resolution images of every nearby galaxy, which in this particular case the caption describes as follows:

UGCA 307 hangs against an irregular backdrop of distant galaxies in this image from the NASA/ESA Hubble Space Telescope. The small galaxy consists of a diffuse band of stars containing red bubbles of gas that mark regions of recent star formation, and lies roughly 26 million light-years from Earth in the constellation Corvus. Appearing as just a small patch of stars, UGCA 307 is a diminutive dwarf galaxy without a defined structure — resembling nothing more than a hazy patch of passing cloud.

The red regions of star formation are significant, as they indicate that even in a tiny galaxy like this it is possible for there to be enough gas and dust to coalesce into new stars.

Astronomers living on a world inside this galaxy have an advantage over astronomers on Earth. There is no large galaxy like the Milky Way blocking their view of the cosmos in one direction. They can see it all, even in directions looking through UGCA 307.

Russia and China launch satellites

9:20 am

Two launches today in Russia and China.

First China used its Long March 2C rocket to launch a “remote sensing satellite” into orbit. No other information about the satellite was released. Nor was any information about whether the rocket’s first stage landed near habitable areas.

Next Russia used its Proton rocket to launch a classified satellite, likely a military surveillance satellite, into orbit. Like China Russia launches from an interior spaceport, with its first stage falling “in Karaganda Region of Kazakhstan,” with the second stage landing in drop zones in Russia. Russia, which has been doing this regularly for more than a half century, has always done a good job either avoiding habitable areas with the first stage crash, or keeping such stories out of the international press.

The 2023 launch race:

16 SpaceX
9 China
4 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise still leads China 17 to 9 in the national rankings, and the entire world combined 17 to 15. SpaceX alone is now tied with the entire world, including all other American companies, 16 all.

Curiosity looks ahead: Which way to go?

10:23 pm

Curiosity's view on March 11, 2023
Click for high resolution version. For original images, go here and here.

Overview map

How about a bonus weekend cool image! The panorama above, created from two pictures taken on March 11, 2023 by the right navigation camera on the Mars rover Curiosity, gives us a wonderful view of the alien Martian terrain that the rover is presently within. It also shows us the dilemma mission planners have in planning the rover’s future travels.

The red dotted line on both the panorama and the overview map to the right indicates the planned route. The yellow lines on the map indicates the approximate area viewed by the panorama. The blue dot marks Curiosity’s present position, where it is presently in the middle of a drilling campaign in the marker layer where it sits.

The plan had been to travel to the east of what I like to call the the hill of pillows (in the middle of the panorama). Yet, it appears from this navigation image that the terrain might be less difficult to the west. Both routes will get the rover to its goal in Gediz Vallis.

I have no idea what the mission planners will decide to do. I am just a tourist going along for the ride, and sharing the journey with my readers. This is the first time any human spacecraft has ever traveled through such mountainous terrain on any planet.

Relativity scrubs launch today again

2:06 pm

Relativity today was once again unable to complete the first launch of its Terran-1 prototype rocket.

The failure to launch was not for want of trying. The first countdown was first put on hold at T-1:10 when a boat entered the range. Once removed, the launch team picked up the count from that point without any recycle, but at T-0 the rocket’s internal computer sensed an issue and aborted the launch.

The launch team then reassessed, adjusted that issue, and tried again for a launch at the last second of the launch window, essentially duplicating the circumstances of an instantaneous launch window. The count this time got down to T-45 seconds when once again the rocket’s internal computer sensed an issue and aborted the launch.

No word yet on when the company will try again. If anything, Relativity’s launch team is getting a lot of practice and training with each launch attempt, critical knowledge needed for future launches.

Some space startups threatened by Silicon Valley Bank failure

9:41 am

Link here. The companies mentioned in the article are Astra, BlackSky, Planet, Redwire, Rocket Lab, and Space Perspective.

Rocket Lab has about 8% of its cash assets now trapped by the closure. All the companies had loans from Silicon Valley Bank, some of which were paid off prior to the crash. This quote suggests the situation is critical for some space startups:

“It’s a very serious situation,” said a space sector entrepreneur who asked not to be identified. “Our balance is suddenly only $450. There has been no communication from SVB even after the event became known. Our primary SVB liaison, who has been very attentive in the past, is unreachable by any means. It’s appalling.”
