  • Blue Origin shows off the now welded first stage tanks of its New Glenn rocket

    • It is assumed these are for the first launch, whenever that might be. Since there are no workers on the factory floor, Jay speculates it was taken after hours. I wonder, since this lack of activity has been seen in every such picture of this rocket assembly operation. I really wonder how many people even work there.

 

  • Jeff Bezos sells off $240 million more Amazon shares

    • Though the reporters on the CNBC video at the link speculate this money is for Blue Origin, there is no evidence of this. In fact, recently Bezos has appeared to donate almost all his stock sale cash to leftist political charities, not Blue Origin.

Martian ice sheets sublimating like peeling paint?

2:02 pm

Overview map

Martian ice sheets resembling paint peeling
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on September 19, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The features are described as “ribbed terrain” in the label. To my eye they more resemble flakes of peeling paint, most especially the mesas in the lower left. On the full image there are many more examples that resemble old paint peels, barely attached to the wall.

The white dot on the overview map above marks the location, deep inside the 2,000-mile-long strip in the northern mid-latitudes I dub glacier country, because everything seems covered by glacial features. This location is at 42 degrees north latitude, where plenty of near-surface ice features are found on Mars.

At first glance it looks like the top “paint-peel” layers to the south have been slowly sublimating away, leaving behind the smooth plain to the north. The problem is that this smooth area in the full image actually appears to be a glacial ice sheet of its own, filling all the low areas between mesas.

In other words, we are probably looking at layers and layers of ice sheets, each created during a different Martian climate cycle, caused by the wide swings of the planet’s rotational tilt, or obliquity.

The location is within Arabia Terra, the largest transitional zone on Mars between the northern lowland plains and the southern cratered highlands. Thus it sits above the glaciers that fill the lower regions of chaos to the north. What we have here is terrain that will eventually become chaos terrain, as the narrow faults and cracks are slowly widened into canyons by the cycles of glacial activity.

Real pushback: Soldiers punished by Biden for refusing jab now sue for billions

11:48 am

Fighting the left's playbook
Fighting the left’s playbook

Bring a gun to a knife fight: The many military soldiers punished by Biden for refusing the Covid jab have now filed a class action lawsuit for what they expect to be worth billions.

Former troops are suing the U.S. government for lost pay and benefits due to the Biden administration’s military vaccine mandate, one of the lawyers who successfully brought down the Anthrax vaccine told Breitbart News.

Attorney Dale Saran, a retired Marine, and fellow attorneys Andy Meyer and Brandon Johnson are representing the former troops in three separate lawsuits they plan to turn into a class action lawsuit on behalf of all service members who were either kicked out or illegally ordered to stop drilling, resulting in loss of pay or benefits. Saran said the amount is in the “billions.”

“It’s worth billions. That’s just flat-out. That’s what it is in backpay. It’s billions of dollars,” he said.

Though only about 8,000 active-duty troops were kicked out of the military due to the Biden jab mandate, the lawyers estimate another 80,000 to 100,000 soldiers are due compensation for lost benefits because they were made inactive or forbidden from participating in drill activities.

The lawsuit has been filed in U.S. Court of Federal Claims, a specialized court where illegal military discharges are heard. Lawyer Saran won a similar suit in that court over the military’s anthrax mandates back in the late nineties. The case now is likely stronger because, as he notes,

They were basically [without] the benefit of any due process. No boards were held. They didn’t hold any administrative separation boards; they didn’t hold any hearings. They didn’t do any federal recognition boards; none of the administrative or judicial procedures were used. They just flat-out did it.

This willful refusal to follow the law has been typical behavior by the left since the start of the Wuhan panic. The law no longer applies to them. They want to do something, they do it, even if it is illegal and hurts someone else. Shutter businesses illegally, silence opponents illegally, favor some races illegally, fire soldiers illegaly, mandate jabs and masks illegally, demand health records illegally: All okay because the good people are doing it! How dare you question their righteousness?

The worst aspect of these violations of law has been the meek willingness of everyone to go along with them. Most shameful.

Eutelsat-OneWeb gets license approval in India

9:21 am

Less than two weeks after SpaceX obtained regulatory approval to offer its Starlink system in India, Eutelsat-OneWeb (newly merged) has now gotten its own approval.

Eutelsat-OneWeb is half owned by an Indian investment firm, so it is no surprise it obtained this approval soon after SpaceX. The two companies will now be competing aggressively for business in this giant country, whose technological capabilities has been renewed in recent years by the abandonment of a socialist/communist government for a leadership focused on encouraging freedom, capitalism, and competition.

NASA laser communication experiment succeeds in sending data from beyond Moon

9:12 am

A NASA laser communication experiment on the asteroid probe Psyche succeeded on November 14, 2023 in sending data to and from the spacecraft as it traveled away from Earth.

NASA’s Deep Space Optical Communications (DSOC) experiment has beamed a near-infrared laser encoded with test data fromnearly 10 million miles (16 million kilometers) away – about 40 times farther than the Moon is from Earth – to the Hale Telescope at Caltech’s Palomar Observatory in San Diego County, California. This is the farthest-ever demonstration of optical communications.

Riding aboard the recently launched Psyche spacecraft, DSOC is configured to send high-bandwidth test data to Earth during its two-year technology demonstration as Psyche travels to the main asteroid belt between Mars and Jupiter. NASA’s Jet Propulsion Laboratory in Southern California manages both DSOC and Psyche.

The experiment seeks to demonstrate the advantages of optical communications, which if successful could have data speeds ten to a hundred times faster than standard high band radio communications. While the technology has been demonstrated as far away as the Moon, this is the first successful test from deep space, a key advance that suggests the technology is becoming mature enough to use on planetary missions.

If so, it could largely replace or at least supplement the various radio-antenna networks on Earth, such as NASA’s Deep Space Network, with smaller and more efficient communication links.

North Korea launches spy satellite

8:59 am

In its third attempt this year to launch a spy satellite, North Korea today succeeded at last, its new Chollima-1 rocket lifting off from Sohae spaceport on the country’s western coast and placing in orbit what is probably a relatively primitive spy satellite with a limited lifespan.

Though launched on the coast, the flight path crossed over North Korea, with drop zones for the rocket’s lower stages in the Yellow and East China seas. The previous two launch failures (in May and August) did the same, with South Korea salvaging stages and the satellite from the first failure. The data recovered suggested the spy satellite was of “no military utility” according to the South Korean military.

As usual, U.S. and South Korean officials condemned the launch, calling it a violation of UN sanctions. Note too that this was not North Korea’s first successful launch, having managed launches in 2012 and 2016 previously, with a different rocket.

Because this was North Korea’s first success in 2023, the leader broad in the 2023 launch race remains unchanged:

86 SpaceX
52 China
14 Russia
7 Rocket Lab
7 India

However, the launch was the 180th in 2023, setting a new global record for the launches in a single year, eclipsing the record set last year. Since Sputnik in 1957 the average number of successful launches globally was generally less than a hundred. This year it is very possible the world will double that average, almost entirely because of American private enterprise, which leads China 98 to 52 in successful launches, and the entire world combined 98 to 82. SpaceX by itself still leads the rest of the world (excluding American companies) 86 to 82.

SpaceX launches 23 more Starlink satellites

12:56 am

SpaceX early last night continued its campaign to reach 100 launches in 2023, its Falcon 9 rocket launching for the third time in just over four days, lifting off from Cape Canaveral carrying 23 more Starlink satellites into orbit.

The first stage completed its fifteenth launch, landing on a drone ship in the Atlantic.

The leaders in the 2023 launch race:

86 SpaceX
52 China
14 Russia
7 Rocket Lab
7 India

American private enterprise now leads China 98 to 52 in successful launches, and the entire world combined 98 to 81. SpaceX by itself is now leads the rest of the world (excluding American companies) 86 to 81.

With this launch, the number of successful orbital launches in 2023 now matches the record total of 179 set last year. With a little more than five weeks to go, expect that number to top 200 before the year is out, especially because China has historically tended to launch a lot of rockets in December.

Ancient volcanic vent on Mars

2:43 pm

Volcanic vent on Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on May 28, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The picture label describes it as a “Low Shield Vent and Pit Northeast of Arsia Mons,” suggesting these depressions are volcanic in nature. We know the pit in the lower left is not an impact crater because it has no raised rim of ejecta. Instead, it looks like a collapsed sinkhole, formed when the ceiling above a void could no longer support its weight. Similar, the trench to the northeast is aligned with the downhill grade to the northeast, with its features suggesting a vent draining in that direction.

The ample dust inside the trench and pit suggest that it has been a very long time since this vent was active. Research suggests volcanic activity last occurred in this region from 10 to 300 million years ago, so that gives us a rough estimate of this vent’s age. Since then any dust that is blown into it will tend to become trapped there.

North Korea announces it will attempt orbital launch of spy satellite this week

10:26 am

North Korea has announced that it will make a third attempt to place a spy satellite into orbit this week, lifting off anytime between November 22nd and December 1st, with drop zones of the rocket’s lower stages over the Yellow and East China seas.

The North initially planed to make the third launch attempt in October following two botched launches — in August and May. But it did not press ahead with the plan last month, raising speculation that it might need more preparation time.

As expected, South Korea has protested. It is also likely gearing up to attempt to recover as much debris from the launch as possible, as it did successfully on the previous launches.

High altitude balloon company World View will not go public

10:18 am

The high altitude balloon company World View has ended its negotiations, begun early this year, with a venture capital investment firm to merge and make its stock public.

In a Nov. 17 statement, World View and Leo Holdings Corp II announced they were canceling plans announced in January to merge. The decision to end the merger was mutual, the companies said.

The companies did not give a specific reason for calling off the deal. “Over the course of 2023, World View received strong interest from potential investors,” the companies stated. “However, given challenging market conditions, World View and Leo jointly determined that it was the best course of action at this time to not proceed with their previously announced transaction.”

There could be a lot of good and bad reasons this deal fell through. Mostly likely World View officials saw the generally negative consequences experienced by other space startups that went public in this manner in the past few years, and decided it better to hold off.

Rocket engine startup Ursa Major enters solid-rocket motor business

10:08 am

Recognizing a desperate need of the military to ramp up production of solid rocket motors after much of its missile stockpile has been depleted by President Biden’s large gifts to the Ukraine, the rocket engine startup Ursa Major has now announced it is entering solid-rocket motor business.

Describing the solid rocket motor [SRM] market as “plagued by a broken supply chain and an overextended industrial base,” the Colorado startup today announced its plans to use its 3D printing techniques developed for liquid rocket engines to speed production of solid-fuel propulsion systems. Ursa Major has received several contracts from the Air Force Research Laboratory for its work on a new rocket engine for heavy space launch vehicles, as well as a hypersonic engine.

“Traditional SRM providers rely on production lines that are difficult to re-tool, expensive to ramp up, and dependent on a significant workforce to operate,” the company said in a press release touting its “new approach” to manufacturing, dubbed Lynx. “Ursa Major is offering a new way to scale production of SRMs,” Ursa Major CEO Joe Laurienti said in the press release. “Lynx meets the defense industry’s need for a faster, cheaper, scalable, and flexible SRM production process that results in better-performing solid rocket motors.”

The article also notes that at present the military is dependent on only two companies for new solid rockets, Northrop Grumman and Aerojet Rocketdyne (now L3Harris). The article also notes that it could take anywhere from five to eighteen years for these companies to replenish the depleted stocks.

The bottleneck however has brought several new players into the field, with the military eager to issue contracts to these new players. This decision by Ursa Major is thus a very good one.

India now plans robotic lunar sample return mission

9:58 am

Following the successful landing of Vikram on the Moon, officials of India’s space agency ISRO have announced it is considering a much more ambitious follow-up, Chandrayaan-4, that will not only land on the lunar surface with a much larger rover, it will also dig up some samples and return them to Earth.

The spacecraft will travel to the moon, land, collect samples, and then connect to another module in space. The module will then return to Earth orbit. As the two modules approach Earth, they will separate, with one part returning to Earth and the other will keep orbiting the planet. Desai described the mission as ambitious, stating, “Hopefully, in the next five to seven years, we will meet the challenge of bringing samples from the moon.”

For return to Earth, Desai said that the mission would need two launch vehicles containing four modules (Transfer module, Lander Module, Ascender Module and Re-entry module). RM and TM would be Parked in the lunar orbit and two will go down from which Ascender Module will get separated from lander module and would collect the sample.

If India does this mission, while also completing its first manned mission during that time frame, it will place itself in direct competition with China and the U.S., and in fact will be getting close to matching both in capabilities.

Musk: Next Starship/Superheavy test launch could happen in only 3 to 4 weeks

9:50 am

Superheavy & Starship, on their way
Superheavy & Starship, shortly after liftoff on November 18th

In a tweet on November 19, 2023, Elon Musk revealed that SpaceX could be ready for its next Starship/Superheavy test launch in only a matter of weeks, assuming federal red tape doesn’t get in the way.

Starship Flight 3 hardware should be ready to fly in 3 to 4 weeks. There are three ships in final production in the high bay (as can be seen from the highway).

In reporting on the second test launch on November 18, 2023, I noted that with prototypes ready to go SpaceX could probably launch within a month. Musk has now confirmed that assessment.

I also predicted that the FAA and Fish & Wildlife would not allow such a thing, and though they will determine there is no reason not to launch again, they will not issue a launch licence until the February/April time frame.

I want this prediction clearly on the record. It is important for the public to know the source of these delays.

It is also important for the press to apply pressure on these government paper pushers so they don’t feel encouraged in their intransigence. When I made a similar (and wholly accurate) prediction in May about the second launch, many in the press criticized that prediction (directly and indirectly) for daring to say bad things about government regulators. Now it appears that others in the press are no longer so naive, and are willing to note the slowness of the licensing process.

The regulators might not want to stand in the way and are simply following procedure. The press however mustn’t treat them gently. It must hold their feet to the fire to make sure they don’t take their time doing so.

Moreover, we have seen fewer headlines claiming falsely that the rocket “blew up” or “exploded.” Instead, a large percentage of the press now got it right and noted the mission’s success and that the destruction was not an accident but part of the self-destruct system.

After the last launch I lambasted the press for getting these facts wrong. Maybe holding their feet to the fire forced a reassessment and better reporting this time around.

Musk: Starship/Superheavy launchpad essentially undamaged after launch

12:37 pm

Superheavy launchpad post launch
Click for original image.

In a tweet posted only a short time ago, Elon Musk announced that the redesigned and rebuilt Boca Chica launchpad experienced little or no damage during the launch of Superheavy/Starship on November 18, 2023.

Just inspected the Starship launch pad and it is in great condition!

No refurbishment needed to the water-cooled steel plate for next launch.

Congrats to @Spacex team & contractors for engineering & building such a robust system so rapidly!

Musk included the picture to the right in the tweet, showing the essentially undamaged launchpad pad. A close looks suggests there was some damage to the rear pillar near the top, but overall it appears the next launch could occur here very quickly.

Musk of course is wrong about who he credits for redesigning and rebuilding this launchpad. The real credit must go to the FAA bureaucrats who led the investigation and must have clearly guided those SpaceX engineers and contractors. To expect private citizens to think for themselves and come up with such difficult engineering without supervision from government paper-pushers in Washington is unreasonable and unfair. Maybe the Biden Justice Department should consider another lawsuit against Musk, this time for spreading more disinformation!

Moreover, who cares that the launchpad deluge system worked exactly as planned? We must allow Fish & Wildlife to spend several months now to investigate this launch — as well as write a long report of many words — to make sure that deluge of water did not harm any of the wildlife that lives on this barrier island, which has a water table of essentially zero and is flooded regularly and repeatedly by storms over time.

Anyone who disagrees is clearly a bigoted racist who wants to harm little children!

Jan 6th tapes prove Biden prosecutors knowingly falsified the charges that caused Matthew Perna to kill himself

12:11 pm

Matthew Perna, dead because he expressed his opinion
Matthew Perna, essentially murdered by the Biden Justice Department

They’re coming for you next: Thirty-seven-year-old Matthew Perna came to Washington DC on January 6, 2021 to peacefully protest Joe Biden’s election. During those protests, Perna admitted he entered the Capitol through a door that had been opened by others (possibly government security police themselves). While inside he said he had walked through the building for a few minutes, didn’t touch or damage anything, and simply stayed within the normal walking path for visitors as he took pictures.

For this “criminal activity,” Biden prosecutors at the Department of Justice had charged him with multiple crimes, including a felony for committing terrorism that could have resulted in a twenty-year prison sentence. While Perna was willing to accept a trespassing misdemeanor — he recognized he had entered a closed facility without clear authority — the felony for terrorism crushed him. He knew the January 6th trials were imposing the harshest penalties. He knew the prosecutors and judges were not taking reasonable plea deals. And he knew that even if he agreed to a deal, the best he could expect would still be many months or even years in prison.

This unjust fate was something he could not face. On February 25, 2022 he killed himself.

Biden prosecutors immediately thereafter dropped the trumped-up charges against him, admitting that the felony charge itself would likely have been dropped during trial.

In other words, the government not only rubbed salt in the wounds of his family, it admitted openly that its charges against Perna were a sham to begin with.

We now have visual proof that Perna was innocent, and that proof was in the hands of federal prosecutors from day one.

Webb: Needles scattered near the center of the Milky Way

9:14 am

Needles in space
Click for original image.

Scientists today released a new false-color infrared image taken by the Webb Space Telescope of a region about 300 light years from the center of the Milky Way, dubbed Sagittarius-C. That picture is to the right, cropped, reduced and sharpened to post here. The blue or cyan regions are ionized hydrogen clouds, and with this image were revealed to be much more extensive than expected. The orange blob near the center is a densely packed cluster of protostars, the starlight blocked by the cloud of material.

The most interesting feature however are the needle-like structures within that ionized hydrogen, oriented in all directions in a manner that looks completely random. Though such needles have been seen previously, the data here is far more detailed, and might eventually help astronomers figure out what the heck these features are and what caused them.

SaxaVord spaceport on Shetland Islands experiencing funding/regulatory problems

9:27 am

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.

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?

10:55 am

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

9:35 am

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

9:23 am

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

8:59 am

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.

Sierra Space shakes up its staffing

8:44 am

Sierra Space yesterday did a major staffing shake up, laying off 165 workers while shifting 150 with secruity clearances from its parent company Sierra Nevada.

Sierra Space this week shipped the first Dream Chaser, named Tenacity, for pre-launch testing at NASA’s Armstrong facility in Ohio. The layoffs began soon after, the Sierra Space spokesperson said, noting the company conducted a surge in hiring this year to complete work on the Tenacity spacecraft.

With Tenacity shipped, Sierra Space’s spokesperson said the company is realigning to focus on the operations phase of Dream Chaser’s first mission, as well as on classified national security work. The latter part of Sierra Space’s realignment includes adding nearly 150 employees with security clearances from Sierra Nevada Corp., the aerospace and defense contractor owned by Fatih and Eren Ozmen, which the space company was spun out of two years ago. Sierra Space’s spokesperson said the company is creating a national security space team to work on several classified contracts.

This shift suggests that at least in the short run, Sierra is putting more focus on future military contracts rather than its civilian manned space projects like its LIFE space module (for the Orbital Reef space station) and future manner versions of its Dream Chaser mini-shuttle. I wonder if the company is having more internal doubts about Orbital Reef and its main partner, Blue Origin. Unlike the stations being built by Axiom and Voyager Space, which have already garnered contracts from both national and international customers, Orbital Reef has not done the same. There could be great doubts in the space community it will be built because of Blue Origin’s absymal record for building anything.
