SaxaVord spaceport on Shetland Islands experiencing funding/regulatory problems

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea,
updated to include Esrange spaceport in Sweden.

According to a report in the British press today, construction of the SaxaVord spaceport on the Shetland Islands has stopped because of lack of funds.

Shetland-based DITT declined to comment but sources have confirmed its bills have not been paid. A source said: “This is a huge construction project and you need to have the money to complete it.

…“DITT’s bills stopped being paid and so the company had no choice but to stop work until things are resolved. It would be great to see rockets blasting off into outer space from Shetland, but at the moment it seems more pie in the sky.”

This lack of work was noted in August by a local Shetland new source. It is now three months later and the work stoppage still continues.

The article also noted this comment from a SaxaVord official: “SaxaVord continues to have excellent dialogue with the authorities and is fully expecting to receive its spaceport licence very soon from the Civil Aviation Authority [CAA].” That license application however was submitted in November 2022, one full year ago. Apparently the CAA is doing the same to SaxaVord that it did to Virgin Orbit. With Virgin Orbit the CAA delayed issuing its launch permit by more than six months, during which the company could do no launches, make no money, and eventually went bankrupt when that launch failed and it no longer had the resources to recover.

Now the CAA is twiddling its thumbs for so long in issuing SaxaVord its spaceport license that launch business is shifting elsewhere and the spaceport is beginning to run short of cash. In January spaceport officials had predicted the first launch there would occur by the fall of this year. The fall is now passing and there is no sign of any launch soon, with construction halted.

Expect the business that was originally intended for the two British spaceports in Scotland to increasingly shift elsewhere. The spaceports at Andoya in Norway and Esrange in Sweden have an opportunity to pick up some business.

SpaceX successfully launches Superheavy and Starship

Superheavy & Starship, on their way
Note how all 33 Superheavy engines are firing.

SpaceX this morning successfully launched its Superheavy/Starship heavy lift rocket into its test orbit.

The test flight achieved far more than the first test in April. First, during the entire flight of Superheavy all 33 Raptor-2 engines fired normally. None cut out prematurely. Then at very risky hot fire stage separation — where the second stage (Starship) ignited prior to separation from Superheavy — the correct number of engines shut down, Starship’s engines fired, and Superheavy successfully separated and began its maneuvers for a soft splashdown in the Gulf of Mexico.

At that point mission controllers issued the self-destruct command to destroy Superheavy. Though it appeared that the stage was struggling to flip for its controlled return to Earth, it is also very likely that mission controllers wanted to test that flight termination system after its not perfect performance on the first test flight. Then, the self-destruct command did not activate the instant the command was given, being delayed by about 40 seconds. This time it appeared it worked as planned.

SpaceX launches 23 Starlink satellites

While everyone is focused on the Starship/Superheavy launch scheduled for tomorrow at 7 am (Central) at Boca Chica, SpaceX tonight launched another 23 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage successfully completed it eleventh flight, landing on a drone ship in the Atlantic.

The leaders in the 2023 launch race:

84 SpaceX
52 China
14 Russia
7 Rocket Lab
7 India

American private enterprise still leads China 96 to 52 in successful launches, and the entire world combined 96 to 81. SpaceX by itself is now leads the rest of the world (excluding American companies) 84 to 81.

The southernmost extent of Mars’ youngest lava flood event

The southernmost edge of Mars' youngest lava event
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on August 24, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

Labeled “flow margin in Elysium Planitia,” it shows the very edge of what scientists believe was the most recent large lava event on Mars, dubbed the Athabasca Valles, that is thought to have occurred only 600 million years ago. In only a matter of weeks the fast flowing lava covered a region about the size of Great Britain. What we see here is the southernmost edge of that flow, with the smooth terrain on the west an older lava flood plain, covered by the new flood lava from Athabasca on the east.

The polygon cracks likely indicate cracks that formed during the hardening process (like the polygon cracks in drying mud). Hot lava then pushed up from below to form the ridges. It is also possible the ridges are what scientists call “wrinkle ridges,” formed when material shrinks during the drying process.

Salt glaciers on Mercury?

From Figure A1 of paper
From Figure A1 of paper.

Based on a new analysis of data from the Messenger spacecrat that orbited Mercury from 2011 to 2015, scientists today posited the possibility that salt glaciers exist on Mercury and have reshaped its terrain in manner vaguely comparable to what Mars Reconnaissance Orbiter (MRO) has found on Mars.

You can read the paper here [pdf]. The image to the right, enhanced by the scientists to bring out the faint blue in the hollows, is remarkably reminiscent of the hollows and scallop terrain found in many places in the high Martian latitudes. From its conclusion:

Detecting widespread elemental volatile surface compositions, ubiquitous sublimation hollows, and extensive chaotic terrains has significantly reshaped our perception of Mercury’s geological past. These observations collectively point to the presence of volatile-rich strata spanning several kilometers in depth and likely formed before the [Late Heavy Bombardment] (∼3.8 billion years ago). This notion challenges the conventional view of a volatile-depleted Mercurian crust.

The morphologies within Mercury’s Raditladi basin bear a striking morphologic resemblance to glaciers on Earth and Mars, suggesting their origin from an impact-exposed [volatile-rich layer], likely containing halite. Our numerical simulations show that the unique rheological properties of halite, including the high thermal sensitivity of its viscosity, reinforce this hypothesis. These glacier-like features occur beyond the chaotic terrain boundaries, indicating a potentially global yet concealed, volatile-rich upper stratigraphy. We posit that the exposure of these volatile-rich materials, instigated by impact events, could have been instrumental in the formation and evolution of hollow features, signifying a complex geodynamic history of volatile migration and redistribution, essentially interconnecting some of the oldest and youngest stratigraphic materials on the planet.

The scientists do not have enough information as yet to determine if these glaciers are still active or not. Moreover, the theorized layer of volatile material near the surface remains unconfirmed, requiring in situ investigation to determine its existence with certainty. Like Mars, if it exists it likely only does so in the high latitudes.

Researchers confirm it was a Chinese rocket stage that impacted Moon in 2022

Impact, before and after
The crash site is the double crater in the
lower image.

Researchers have now confirmed that the unknown rocket stage that impacted the Moon in 2022 was from a Chinese rocket, a Long March 3B that launched China’s Chang’e-5 lunar sample return mission in November 2020.

“In this paper, we present a trajectory and spectroscopic analysis using ground-based telescope observations to show conclusively that WE0913A is the Long March 3C rocket body (R/B) from the Chang’e 5-T1 mission,” the researchers, led by Tanner Campbell, a doctoral student in the UA’s Department of Aerospace and Mechanical Engineering, wrote in a study that came out Thursday (Nov. 16) in the Planetary Science Journal. These two lines of evidence — how the object was moving and what it was made of — leave little doubt about WE0913A’s provenance, Campbell and his colleagues report.

The data, combined with the unusual double crater caused by the impact, also suggests that this stage had additional unknown equipment at its top, matching the mass of its engines at the bottom. Since the Chinese continue to deny it was their stage and have said nothing about it, we have no idea what that extra equipment might have been.

German rocket startup signs deal with Norwegian spaceport

Map of northern European spaceports

The German rocket startup Isar Aerospace has signed a deal to provide the Andoya spaceport in the north of Norway with a new flight tracking and safety system, to be used by all launches including Isar’s own Spectrum rocket.

The purpose of the autonomous flight tracking system is to precisely and reliably keeping track of the Spectrum launch vehicle’s position, speed and direction of travel as it ascends to orbit, which is important to guarantee Andøya Spaceport’s flight safety requirements. The objective is to further evaluate the use of the system in enabling automated flight termination functionality for launches by Andøya Spaceport’s ground system, autonomously triggering an abort of the mission if ever operational parameters of the launch vehicle are out of bounds.

This announcement today illustrates the rising competition between German rocket startups and European spaceports. Yesterday the Saxavord spaceport in Scotland and another German rocket startup, HyImpulse, announced their own launch deal. Today’s announcement is the response from Andoya and Isar.

Today’s announcement also increases the pressure in the UK’s Civil Aviation Authority (CAA) to get its regulatory act together. Andoya is positioning itself as a good alternative to the two new British spaceports in Scotland, as shown by the red dots on the map above, should red tape in the UK slow launches there.

House committee delays vote on commercial space bill due to new White House proposal

Because of the sudden announcement by the White House of its own version of a new commercial regulatory space bill, the House Science committee was forced to delay the voting on November 15, 2023 of its own new commercial space bill, put forth by Republicans.

The committee met Nov. 15 to mark up the Commercial Space Act of 2023 and one other bill. At the end of the markup, lasting more than three and a half hours including a recess, the committee’s chairman, Frank Lucas (R-Okla.) said the committee would delay votes to advance both bills until after the Thanksgiving break because of votes on the House floor and “and the nature of additional information that has become available to us.”

The latter comment appeared to be a reference to a legislative proposal released by the White House’s National Space Council less than an hour before the markup regarding a mission authorization concept for new space activities. That proposal would establish a system where both the Commerce Department and the Transportation Department would oversee activities not regulated today, based on the type of activity.

The House bill, introduced Nov. 2 by Lucas and space subcommittee chairman Rep. Brian Babin (R-Texas), would create its own mission authorization system at the Commerce Department. It would also direct Commerce to hand over responsibility for a civil space traffic coordination system to a consortium led by an academic or nonprofit organization, rather than keeping it within the Office of Space Commerce as currently planned. Lucas, in his opening remarks, said he was aware of the new White House proposal but has reservations about it. “These proposals, I fear, simply go in the wrong direction and hurt rather than support America’s space industry,” he said.

Both bills were aimed at realigning the regulatory regime governing private space activities. The House bill’s final form apparently had been written with a lot of industry input. The White House bill, supported by Democrats, appears designed instead to clamp down on commercial space by allowing the federal bureaucracy to regulate everything.

Both bills unfortunately give too much power to the federal government, though the Republican bill at least tries to shift some of that power to the private sector, where it belongs.

One of the main reasons we have had a rennaisance in commercial space in the past decade is that there has been little regulation. The private sector has been left to regulate itself, and it has generally done so very successfully because of the invisible hand of free market forces. Build things right and the world beats a path to your door. Do it badly and no regulation is needed, you go out of business.

Modern Americans no longer trust these fundamentals of freedom and capitalism, and so we have a rush by government to establish “rules,” none of which will really accomplish anything but slow development and innovation and squelch this emerging industry.
