Bankrupt Virgin Orbit is dead, its assets purchased by a variety of different companies

9:34 am

After failing to find a single buyer for the whole company, Virgin Orbit is now officially dead as a company, its assets broken up during bankruptcy proceedings and purchased by several different companies.

Rocket Lab paid $16.1 million for Virgin Orbit’s main manufacturing facility in California, which it intends to use for developing its larger Neutron rocket. Stratolaunch paid $17 million for the company’s 747 airplane and related equipment. Launcher, a former rocket startup that is now owned by the space station startup Vast, paid $2.7 for the company’s test site in Mojave, California, which it plans to use for static fire engine tests of a rocket engine it is developing for sale to others. A liquidation company purchased other assets, while the various LauncherOne rockets under construction remain unsold.

It is essential the reasons for this failure are made very clear. The destruction of this company occurred because regulators in the United Kingdom prevented it from launching from within the UK for almost half a year, during which it could not perform other launches elsewhere and therefore earn revenue. It then ran very low on cash, and when the UK launch failed in January, the company no longer had the resources to weather to time necessary to complete the investigation, fix the problem that caused the failure, and resume launches.

For other rocket startups, it is very important to consider this story before committing to launching in the UK. where you will face major bureaucratic obstacles from its government. Until there is evidence that something has changed, it might be better to consider other launch sites.

Astronomers have now used the Chandra X-ray Observatory and Webb Space Telescope (working in the infrared) to produce spectacular composite false-color X-ray/infrared images of four famous heavenly objects.

To the right is the composite taken of the Eagle Nebula, also known as Messier 16. It was also dubbed the Pillars of Creation when it was one of the first Hubble images taken after the telescope’s mirror focus was fixed in 1993. From the caption:

The Webb image shows the dark columns of gas and dust shrouding the few remaining fledgling stars just being formed. The Chandra sources, which look like dots, are young stars that give off copious amounts of X-rays. (X-ray: red, blue; infrared: red, green, blue)

The other images include star cluster NGC 346 in a nearby galaxy, the spiral galaxy NGC 1672, and the face-on spiral galaxy Messier 74.

Frozen waves of Martian lava?

Frozen waves of Martian lava?
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on March 17, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The science team labeled this a terrain sample image, which implies it was taken not as part of any specific request, but to fill a gap in the camera’s schedule in order to maintain its proper temperature.

What are we looking at? This stippled terrain with curved ridges actually extends quite a distance beyond this image. A MRO context camera picture taken on July 22, 2020 shows its full extent, about 10 miles wide but extending to the north and south about 30 miles total, butting up against a north-south mountain chain to its east that is about seventy miles long with its highest peak about 8,000 feet above this plain.

Lunar Reconnaissance Orbiter spots Hakuto-R1 impact debris on Moon

9:38 am

Hakuto-R1 impact site, before and after
Click for original blink image.

NASA’s Lunar Reconnaissance Orbiter (LRO), scientists have spotted what they think is the impact debris produced when Ispace’s private lunar lander Hakuto-R1 crashed on the Moon on April 25, 2023.

To the right are two LRO images, the first at the top taken prior to Hakuto-R1’s landing attempt. The second at the bottom was acquired by LRO on April 26, 2023, the day after that attempt. The lettered arrows indicate four spots where the scientists identified changes between the two pictures. From the caption:

Arrow A points to a prominent surface change with higher reflectance in the upper left and lower reflectance in the lower right (opposite of nearby surface rocks along the right side of the frame). Arrows B-D point to other changes around the impact site.

According to the LRO science team, these changes suggest different pieces of debris, though it will take more analysis and more images under different lighting conditions to determine more precisely what they have found.

The presence however of four pieces strongly suggests that Hakuto-R1 hit the ground hard enough to break apart. Based on the initial data received during landing, it was thought the spacecraft had touched down softly but then was damaged by some unforeseen obstacle on the ground, such as a large boulder. The LRO image suggests instead that it did not touch down softly at all.

Air Force awards Ursa Major rocket engine development contact

9:13 am

The Air Force Research Laboratory (AFRL) has awarded the rocket engine startup Ursa Major a contract to develop two different rocket engines.

Under the contract, the Colorado-based firm will build and test a prototype of its new Draper engine for hypersonics, and further develop its 200,000-pound thrust Arroway engine for space launch.

…Under the AFRL contract, for which neither the lab or company provided a value, Ursa Major will also build a dedicated test stand for Draper and plans to hotfire the engine within 12 months.

Arroway, on the other hand, is a reusable liquid oxygen and methane staged combustion engine for medium and heavy launch vehicles. Ursa Major first announced development the 200,000-pound thrust engine last August, explaining that when clustered together, Arroway engines could replace the Russian-made RD-180 and RD-181, which are no longer available to US launch firms.

According to Ursa Major’s press release, the AFRL contract will allow further development of Arroway with a hotfire expected in 2025.

Ursa Major already has several contracts for its smaller Hadley engine, from the rocket startups Phantom, Vector, Astra, and the Air Force, and has built more than a hundred so far. The Arroway meanwhile is being developed as an American replacement for the Russian engines used by Northrop Grumman in its Antares rocket.

All in all, it appears Ursa Major is becoming a major challenger to Aerojet Rocketdyne, which in recent years had a lock on most government contracts for rocket engines. That lock resulted in very expensive engines that took years to build. The government (and others) are now finding someone else to provide this service at a better cost and far more quickly. We shall see whether Aerojet Rocketdyne responds to this competition properly, or goes the way of the horse carriage.

SpaceX files to join FAA as defendant in lawsuit trying to shut down Boca Chica

9:01 am

SpaceX on May 19, 2023 submitted a motion to become a defendant in the lawsuit filed by the Center for Biological Diversity (CBD) and others that demands its Starship/Superheavy launchsite at Boca Chica be shut down.

“SpaceX’s Starship/Super Heavy launch program hinges on the FAA’s review and licensing decision challenged here. If the Court were to rule in Plaintiffs’ favor, the FAA’s decision could be set aside, and further licensing of the Starship/Super Heavy Program could be significantly delayed, causing severe injury to SpaceX’s business,” the company said in the motion, which was filed on May 19.

The full motion can be read here [pdf].

SpaceX’s motion notes that it has followed all government regulations in the decade since it established its Boca Chica launch site, and invested more than $3 billion in doing so. The motion points out that “the FAA does not adequately represent SpaceX’s interests” and that the company must participate because the lawsuit will have direct financial impact on its business.

In other words, the big guns are now being hauled out against this lawsuit, which on its face is somewhat weak. We shall see if it can withstand the much more aggressive fight that SpaceX is certain to put up.

Pushback: California loses big for trying to force churches to violate their religious beliefs

1:33 pm

in California’s health system

They’re coming for you next: After California health authorities in 2014 imposed a mandate requiring requiring churches to provide elective abortion coverage to its employees, four churches sued, and after a long court battle, have now won a $1.4 million settlement.

Alliance Defending Freedom [ADF] attorneys represent Skyline Wesleyan Church, located in the San Diego area, in one federal lawsuit, and Foothill Church in Glendora, Calvary Chapel Chino Hills in Chino, and The Shepherd of the Hills Church in Porter Ranch in another. Both lawsuits challenged California’s abortion-coverage mandate. In both cases, the courts ruled that the U.S. Constitution protects the churches’ freedom to operate according to their religious beliefs, which include their belief in the sanctity of unborn lives.

The rulings in both lawsuits (here and here [pdfs]) not only release the churches from the illegal abortion mandate, they both require payments to ADF and the church’s local attorneys to pay all legal costs. Interesting, in both lawsuits Mary Watanabe, the director of the California Department of Managed Health Care (DMHC) was named, and in one case she was the only defendant. Unfortunately, she walks away unharmed, because DMHC will pay for everything, out of tax dollars.

What made the mandate especially egregious is that it was written in league with officials at Planned Parenthood and the ACLU, as shown by emails [pdf] between DMHC and those officials. » Read more

Ancient volcano vent in the Martian southern cratered highlands?

12:14 pm

Ancient volcano vent on Mars?
Click for original image.

The nature of today’s cool image suggests both ancient and more recent geological activity, each coming from entirely different sources but both helping to shape the alien Martian surface.

The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on March 13, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the science team has labeled an “elongated depression,” sitting in the middle of a relatively flat but very rough stippled circular plain about 60 miles in diameter. An MRO context camera picture, taken on February 19, 2012, covered the central strip of this plain, and shows that its surface is equally rough and stippled everywhere, with only a few craters and one or two slight changes in elevation.

So, how does this feature tell us both about the ancient and recent geological history of this spot on Mars?

Jellyfish galaxy plowing its way through the intercluster medium

Jellyfish galaxy plowing through the intercluster medium
Click for original image.

The European Space Agency (ESA) today released another in a series of images taken by the Hubble Space Telescope during the past two years of what astronomers call jellyfish galaxies, so named because such galaxies have tendrils that extend out beyond the galaxy like the tendrils of jellyfish. This new picture is to the right, cropped, reduced, and sharpened to post here, and shows a galaxy about 900 million light years away.

[T]he space between galaxies in a cluster is … pervaded with a searingly hot plasma known as the intracluster medium. While this plasma is extremely tenuous, galaxies moving through it experience it almost like swimmers fighting against a current, and this interaction can strip galaxies of their star-forming gas. This interaction between the intracluster medium and the galaxies is called ram-pressure stripping, and is the process responsible for the trailing tendrils of this jellyfish galaxy.

The arrow in the image indicates the galaxy’s direction of travel through the intercluster medium, resulting in the outer parts of the leading arm to be pushed backward above the galaxy, while material at its rear trail behind. Note also the blue star-forming regions at the galaxy’s bow. The ram pressure is also apparently causing more star formation in this part of the galaxy compared to elsewhere.
