South Korea is in final negotiations to cancel two Russian launch contracts

8:44 am

As has been expected since the beginning of Russia’s invasion of the Ukraine, South Korea is in the process of canceling two Russian launch contracts, with the negotiations apparently now in the final stages.

“The Korea Multipurpose Satellite 6 and the next-generation mid-size satellite Compact Advanced Satellite 500-2, both developed by Korea, were initially scheduled to be launched into space using Russian launch vehicles, but due to the war between Russia and Ukraine and the subsequent international sanctions against Russia, there were uncontrollable circumstances that prevented the use of Russian launch vehicles,” the Ministry of Science and ICT said in a statement.

“Since then, Korea has been negotiating with Russia on the terms of termination of the satellite launch contract and it is currently being finalized.”

South Korea has already found a different rocket for the first satellite, scheduled for launch on Arianespace’s Vega-C rocket when it resumes flights in April 2024 (after completing upgrades resulting from a December 2022 launch failure). As for the second satellite, no public decision has yet been announced, though contract bidding has been on-going.

Meanwhile South Korea is accelerating development of its own Nuri rocket, which it has successfully launched two times already.

Russia in turn no longer has any international customers for its rockets. Its invasion of the Ukraine has cost it hundreds of millions of dollars of lost business, all of which will likely not return for decades.

Astrobotic resumes suborbital test flights of assets purchased from Masten bankruptcy

8:32 am

The startup lunar landing company Astrobotic has resumed flights and testing of the suborbital spacecraft built by the company Masten Space Systems and obtained when that company went bankrupt.

Astrobotic announced Oct. 10 that it completed the first campaign of test flights by Xodiac, a vertical-takeoff, vertical-landing vehicle, since acquiring it and other Masten Space Systems assets last year. Xodiac conducted four flights from Mojave, California, hovering just off the ground to test plume-surface interactions ahead of future lunar landing missions, supporting research by the University of Central Florida.

Xodiac was built several years ago by Masten Space Systems, based in Mojave, and made more than 150 low-altitude flights for a variety of technology demonstration investigations. However, the company filed for bankruptcy in July 2022 and its assets acquired by Astrobotic that September for $4.5 million.

Xodiac is now part of Astobotic’s Propulsion and Test Department, which includes other assets from Masten Space Systems as well as many of its former employees, who say they have picked up where they left off before the bankruptcy.

Astrobotic has also resumed development work on a larger Masten suborbital spacecraft, Xogdor, also designed to launch and land vertically, but actually reach space.

Because Astrobotic is mostly focused on developing lunar landers, Masten’s technology is perfect for refining that capability for landing on the Moon. It is also ideal should Astrobotic decide to develop a reusable rocket for launch from Earth.

October 12 Falcon Heavy launch of Psyche probe faces bad weather

10:09 am

At present there is only a 20% chance that the Falcon Heavy launch of NASA’s Psyche asteroid probe will occur on October 12, 2023 at 10:16 am (Eastern) as planned out of Cape Canaveral.

The launch window only extends until October 25, 2023, after which the entire project would have to be redesigned, requiring a significant delay.

SpaceX has become very adept at threading the needle when weather restricts its Starlink launch abilities, but it has less flexibility with Psyche. To increase its chances it has scrubbed a planned Starlink launch this week from Cape Canaveral in order to give the Falcon Heavy launch more launch opportunities.

Regardless, the live stream can be accessed here.

Software patch saves Europe’s Euclid space telescope

10:03 am

Engineeers have successfully saved Europe’s new recently launched Euclid space telescope by installing a software patch that fixed the telescope’s inability to orient itself properly for long periods.

Shortly after launching on 1 July, the European space observatory Euclid started performing tiny, unexpected pirouettes. The problem revealed itself during initial tests of the telescope’s automated pointing system. If left unfixed, it could have severely affected Euclid’s science mission and led to gaps in its map of the Universe.

Now the European Space Agency (ESA) says that it has resolved the issue by updating some of the telescope’s software. The problem occurred when the on board pointing system mistook cosmic noise for faint stars in dark patches of sky, and directed the spacecraft to reorient itself in the middle of a shot.

The new software essentially reduces the amount of light that enters the pointing system, so that the noise is no longer detected. This means that observations however will have to be longer to obtain the same data, extending the mission.

Euclid’s goal is a follow-up on Europe’s Gaia mission, to map 1.5 billion galaxies in three dimensions. Gaia did it with the stars in the Milky Way. Euclid is looking deeper, requiring far greater precision and accuracy in pointing.

Spanish rocket startup successfully completes first suborbital test launch

10:05 pm

The Spanish rocket startup PLD today successfully completed its first suborbital test launch, a short flight of its Miura-1 prototype rocket, lifting off from its spaceport in Spain.

I have embedded video of the launch below, cued to just before launch. Though the plan had been to recover the first stage using parachutes, it is unclear if this occurred or was even attempted. The launch was at night, making recovery difficult or much slower, and because the broadcast was in Spanish there was no translation,

Regardless, the data from this launch will be used by the company to build its orbital rocket, Miura-5.

Gale Crater as seen by Curiosity from the heights of Mount Sharp

Gale Crater as seen by Curiosity from the heights of Mount Sharp

Overview map
Click for interactive map.

Though Curiosity still lies more than 13,000 feet below the peak of Mount Sharp, in its ten years on Mars it has climbed a considerable distance uphill since leaving the floor of 97-mile-wide Gale Crater, about 2,400 feet. The panorama above, taken today by one of Curiosity’s navigation cameras and rotated and cropped to post here, gives us a good sense of the elevation the rover has gained in that time.

The overview map to the right provides some perspective. Curiosity’s present location is indicated by the blue dot, with the yellow lines indicating the direction of this panorama. Though Curiosity climbed up from that valley on the lower left, none of its route is visible in this picture, as the weaved up from the left and the steepness of the ground hides the lower sections.

The mountain chain in the distance, about 20 to 25 miles away, is the north rim of Gale Crater. Beyond it can faintly be seen other mountains, which form the rim of another smaller crater to the north. The peak of Mount Sharp, about 23 miles to the south and in the opposite direction, forms the wide central peak of Gale Crater, unusual in that it fills much of the crater and rises higher than the crater’s rim, factors which were part of the reason this location was chosen as Curiosity’s landing site.

This picture also allows scientists to get a sense of the dust levels in the Martian atmosphere, which change seasonally depending on dust storm activity. Since it is now summer on Mars, when dust activity is low, the air is relatively clear.

Astronomers detect baffling blue transient far outside any galaxy

11:32 am

Transient in intergalactic space
Click for original image.

Using a variety of telescopes, astronomers have discovered a baffling short-term object that brightens quickly in blue light and then fades.

What makes this discovery even more baffling is that though other such Luminous Fast Blue Optical Transients (LFBOT) have been discovered, all have been within galaxies, while this new discovery is in intergalactic space, as shown by the red bars in the picture to right, taken by the Hubble Space Telescope and cropped, reduced, and sharpened to post here. From the caption:

[An LFBOT] shines intensely in blue light and evolves rapidly, reaching peak brightness and fading again in a matter of days, unlike supernovae which take weeks or months to dim. Only a handful of previous LFBOTs have been discovered since 2018. The surprise is that this latest transient, seen in 2023, lies at a large offset from both the barred spiral galaxy at right and the dwarf galaxy to the upper left. Only Hubble could pinpoint its location. And, the results are leaving astronomers even more confounded because all previous LFBOTs have been found in star-forming regions in the spiral arms of galaxies. It’s not clear what astronomical event would trigger such a blast far outside of a galaxy.

The frequent discovery of such short term transients in the past decade is because there are now many telescopes dedicated to making daily surveys of the entire sky. In the past such quick events were always missed.

ULA’s Atlas-5 rocket launches first two Kuiper satellites

11:16 am

ULA’s Atlas-5 rocket today successfully launched the first two prototype satellites of Amazon’s proposed 3,200-satellite constellation to provide broadband globally in competition with Starlink and OneWeb.

As of posting, the satellites had not yet deployed, with the rocket’s upper stage still firing its engines to bring the rocket to its proper orbit. The live stream unfortunately ended early at this point.

Though the Atlas-5 is being retired, to be replaced by ULA’s still unlaunched Vulcan rocket, about seventeen rockets remain in the company’s launch manifest. All have payloads, so any additional ULA launch contracts must rely on Vulcan.

This was ULA’s third launch in 2023, so it does not change the leader board for the 2023 launch race. The company predicted it would complete ten launches in 2023, a prediction that with less than three months left in the year seems unlikely for it to achieve.

American private enterprise now leads China in successful launches 82 to 45, and leads the entire world combined 82 to 72. SpaceX by itself still trails the rest of the world, excluding American companies, 70 to 72.

Italy’s biggest bank will invest in SpaceX

10:02 am

Italy’s largest bank, Intesa Sanpaolo, announced today that is joining in SpaceX as a private investment partner.

No details of the investment deal were released, but it likely adds a significant amount to the almost $11 billion in investment capital SpaceX has already gotten from the private sector, most of which is being used to develop Starship, Superheavy, and Starlink.

Very clearly, the investment community sees value and large future profits from SpaceX and Elon Musk, and wants to support it. Contrast this with the attitude of the Biden administration and the left, which apparently prefers to squelch this progress for the sake of power.

India’s government confirms its policy to transition to private enterprise in space

9:47 am

Capitalism in space: In a presentation at the International Astronautical Congress in Baku yesterday, one high official from India confirmed the Modi’s government’s new policy to shift is space industry from government-controlled to privately-run.

“A transition is happening in India. We are moving from ISRO [India’s space agency] being the sole player in the space sector to the private sector taking on a more meaningful role,” Pawan Goenka, chairman of the Indian National Space Promotion Authorization Center (IN-SPACe), said at a forum at the 74th International Astronautical Congress in Baku, Oct. 5.

The Indian government approved the Indian Space Policy 2023 in April this year, which follows a number of developments in recent years. “What the Indian Space Policy did was take everything to do with space — satellite communication, remote sensing, space operations, transportation, navigation, everything — and put it into one comprehensive document only 12 pages long,” Goenka said. [emphasis mine]

The highlighted words will sound very familiar to regular readers of this webpage. It describes what NASA has been doing for the past decade, and sums up precisely the recommendations put forth in my 2017 policy paper, Capitalism in Space.

IN-SPACe, the agency Goenka heads, has been tasked with fulfilling this task, and is thus in a direct turf war with ISRO, the space agency that has controlled all of India’s space effort for a half century. How that turf war will play out remains uncertain, though at present IN-SPACe and the Modi government appear to be winning.

It would likely help India’s private industry if the Modi government would make public that 12-page policy statement. So far it has either not released the text, or if it has it has made it impossible for me to find it.

Another lawsuit filed against SpaceX

9:35 am

They’re coming for you next: In what appears to be another example of lawfare by the left against Elon Musk, a female engineer has filed a lawsuit against SpaceX, claiming it discriminated against her in pay.

The lawsuit is absurd, based on the suit itself.

The lawsuit was filed on Tuesday in Los Angeles Superior Court by SpaceX engineer Ashley Foltz, who says she was hired at a salary of $92,000, even though men with similar or less experience were offered as much as $115,000. According to her LinkedIn, Ashley was hired in September 2022 as a propulsion engineer. She did not immediately respond to TechCrunch’s request for comment.

According to the complaint, Foltz learned about the salary discrepancies when a new California law went into effect requiring employers to include pay scale in their job postings. The salary range for her job was $95,000 to $115,000, so SpaceX gave her a raise — but only to the lowest end of the band.

In other words, Foltz didn’t negotiate a good salary when she was hired, and when the California law revealed how low it was, SpaceX immediately raised her salary to the bottom end of its pay scale, indicating also its opinion of her work. I suspect a full review of the salaries the company pays will reveal that women get a wide range of payment, depending on their worth. SpaceX certainly doesn’t discriminate against women, since its CEO is a woman and over the years women engineers have led many major projects.

The lawfare from the left against Elon Musk, one of the most successful Americans in decades, is becoming quite obvious. Besides this private suit, another group of environmentalists are suing SpaceX and the FAA to block future launches from Boca Chica. The Biden administration meanwhile is using numerous agencies to gang up on Musk: the Justice Department is suing it for not illegally hiring illegal immigrants, the FAA and Fish & Wildlife are blocking its Superheavy/Starship test launches, the EEOC is suing Tesla while Justice and the SEC investigate it, and the FTC and SEC are investigating Musk’s purchase of Twitter.

If you still think this full court press of government action is an accident, or entirely innocent, then you are naive beyond belief. Musk is now considered an opponent of the left, and so the left is going after him, and abusing the power of government to do it. It doesn’t care that Musk has produced tens of thousands of new jobs, revolutionized several major industries, and brought wealth to places that were previously poverty-stricken. To the left, the only thing that matters is its hold on power. Threaten that, and it will do whatever it can to destroy you, even if it means people will be starving in the street.

Stoke Space raises $100 million in private investment capital

9:12 am

The rocket startup Stoke Space, which is developing a radically new engine concept for its rockets, has now successfully raised $100 million in private investment capital.

This investment more than doubles the company’s total funding, which now sits at $175 million. The company also announced the official name of its first rocket: Nova.

The funding round was led by Industrious Ventures with participation from the University of Michigan, Sparta Group, Long Journey, and others. Existing investors Breakthrough Energy, YCombinator, Point72 Ventures, NFX, MaC Ventures, Toyota Ventures, and In-Q-Tel also participated. This latest funding round is evidence of strong demand for Stoke’s services, its growing success, and the confidence of investors in its future. As part of this round of fundraising Steve Angel, Chairman of the Board, Linde plc, will join Stoke’s Board of Directors. Angel is also the former CEO of Linde and a member of the Board of Directors of GE.

The company says it will use this money to develop the rocket’s first stage engines, which will follow the same ring nozzle design of its upper stage, a prototype of which it successfully test flew on a short hop last month. Under that design, the engine doesn’t have one central nozzle, but instead the thrust is funnelled out of a ring of tiny nozzles that circle the stage’s outer perimeter. The company believes this design will allow it to return its upper stage safely from orbit for re-use.
