China’s Long March 2D rocket launches military satellite

9:17 am

China yesterday used its Long March 2D rocket to place what is believed to be a military weather satellite into orbit, lifting off from its Jiuquan spaceport in the northwest of China.

No word on where the rocket’s first stage, which uses very toxic hypergolic fuel, crashed within China.

The leaders in 2023 launch race:

73 SpaceX
46 China
13 Russia
7 Rocket Lab

American private enterprise now leads China in successfully launches 85 to 46, and the entire world combined 85 to 74. SpaceX by itself now trails with the entire world combined (excluding American companies) 73 to 74.

Telecommunications company sues Commerce and Defense Departments $39 billion for theft

12:27 pm

The telecommunications company Ligado yesterday filed a $39 billion suit against the Commerce and Defense Departments for stealing use of the communications spectrum granted to it by the FCC for the establishment of a 5G cell phone network.

Ligado’s suit filed in the United States Court of Federal Claims [PDF] makes a number of allegations, including that the Pentagon has “taken Ligado’s spectrum for the agency’s own purposes, operating previously undisclosed systems that use or depend on Ligado’s spectrum without compensating Ligado.”

Those systems, a source close to the case said, are certain classified radars rather than GPS systems.

The suit cites a high-level DoD “whistleblower” who “revealed internal emails and discussions” that the company claims show DoD and Commerce “fabricated arguments, misled Congress in testimony supporting anti-Ligado legislation, and orchestrated a public smear campaign, which included repeating those false claims to the public and threatening Ligado’s business partners with canceling their own government contracts if they worked with Ligado.”

There had been some disagreement about whether Ligado’s use of this spectrem might interfere with GPS as well as other communications services. Nonetheless, the spectrum was legally Ligado’s. If the lawsuit is correct and these government agencies arbitrarilly took possession and used the spectrum illegally, thus preventing Ligado from establishing its business, it would appear to be another example of the arrogant administrative state ignoring the law to grab power.

Once I would have considered a suit like this to simply be a failed company’s effort to recover its losses by blaming the government. I no longer assume such things. Instead, my first thought is that the allegations are true, that bureaucrats in Defense and Commerce conspirated to steal the spectrum for their own uses, and didn’t care that they were violating the law.

The truth could be a combination of all these things, but if so that still tells us some very ugly things about the people who now work in these federal agencies.

Ancient flood lava on the upper slopes of the solar system’s largest volcano

12:40 pm

Ancient flood lava
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on July 13, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

In this one picture can be seen a glimpse of the entire history of the numerous lava eruptions that once dominated Mars when its giant volcanoes were active one to three billion years ago. The three aligned craterlike depressions likely signal the existence of a large lava tube below ground, placed there during an early large eruption, when the volcano was spewing out so much flood lava that such large tubes could form. The smaller meandering surface rills signal later eruptions that carried less flood lava and thus produced a smaller drainage features.

And finally, the rough and cracked appearance of the surface indicates the ancient age of those last eruptions, probably laid down about a billion years ago. Since then, the volcano has been dormant, and the frozen lava here has had time to erode, become roughened, and show signs of slowly wearing away.

SpaceX to offer Starlink for cell phones

9:06 am

SpaceX has now announced that its Starlink internet service will soon be available for cell phones that are already in use, allowing them access to service even in places where no cell towers exist.

Direct to Cell works with existing LTE phones wherever you can see the sky. No changes to hardware, firmware, or special apps are required, providing seamless access to text, voice, and data.

First Starlink will only provide text service in 2024, and then expand to voice and data in 2025.

This capability means that SpaceX will not only be in direct competition with AST SpaceMobile, which recently launched a satellite to test similar capabilities, it will be far ahead of it in that competition. In fact, SpaceX is setting Starlink up as the go-to company for all smartphones and home internet services. By 2025 you will not need any other provider to have phone and internet service globally.

No wonder private investment firms have been willing to invest almost $11 billion in the company. They see big profits on the horizon.

That our federal government dislikes this fact, and is doing everything it can to crush Elon Musk and the company, tells us much about government itself. It isn’t interested in promoting human success. Instead, its instinct is to squelch it.

NASA delays two ISS spacewalks as Russian engineers assess now stopped leak on Nauka module

8:54 am

NASA yesterday confirmed it is delaying by at least one week two ISS spacewalks in order to allow more time for Russian engineers to analyze the causes of the coolant leak on Nauka module and assess its short and long term consequences for the station.

The spacewalks were deferred from their original target dates to allow engineers additional time to complete their analysis of the coolant leak, which occurred on Oct. 9 and has now stopped. [emphasis mine]

The highlighted words are the most important takeaway. The leak has stopped leaking, though we have not been told why. The Russians might have closed off the leaking radiator from the system, or maybe the leak stopped on its own for unknown reasons. More information is clearly required.

First manned Starliner mission now delayed to April 2024

8:45 am

In a press release yesterday that outlined the updates to NASA’s scheduled manned missions to ISS, the agency confirmed that the first manned Starliner mission has now been delayed one more month, from March until April 2024.

The first crewed flight of the Starliner spacecraft, named NASA’s Boeing Crew Flight Test (CFT), is planned for no earlier than mid-April. CFT will send NASA astronauts and test pilots Butch Wilmore and Suni Williams on a demonstration flight to prove the end-to-end capabilities of the Starliner system. Starliner will launch atop a United Launch Alliance Atlas V rocket from Cape Canaveral Space Force Station in Florida, spend approximately eight days docked to the space station, and return to Earth with a parachute and airbag-assisted ground landing in the desert of the western United States. [emphasis mine]

The highlighted words underline the fact that this date is merely a target, and has been announced as part of the entire schedule for all the manned missions to ISS next year, fitting it in between two SpaceX crewed Dragon flights. It assumes Boeing will have the spacecraft ready by then, but based on that company’s track record, that assumption remains dangerous. Boeing has a lot of work to do, including parachute drop tests to fix the parachute cords as well as replacing the flammable electric tape installed throughout the capsule.

Falcon Heavy successfully launches Psyche asteroid mission

8:25 am

SpaceX’s Falcon Heavy rocket this morning successfully launched the Psyche mission to the metal asteroid Psyche, lifting off from Cape Canaveral.

The two side boosters successfully landed at their landing zones at the cape, each completing their fourth flight.

Psyche will now spend the next six years traveling to the asteroid Psyche, first flying by Mars in 2026 to gain some speed to get there. It will then go into orbit around the asteroid for almost two years.

The leaders in 2023 launch race:

72 SpaceX
45 China
13 Russia
7 Rocket Lab

Martian pseudo-frost terrain

Martian pseudo-frost terrain
Click for original image.

Cool image time! It is always dangerous to come to any quick conclusions about what you see from pictures from another planet. The photograph to the right, rotated, cropped, reduced, and sharpened to post here, was taken on August 19, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows what at first glance looks like a surface similar to frosting seen on window panes on Earth in the winter, where water condensation freezes to form crystalline patterns.

Your first glance would be wrong. This terrain is about 120 miles north of the Martian equator, placing inside the dry equatorial regions where no near-surface ice is known to exist. If this geological feature is formed by the same condensation processes that create ice frost, then it must involve the deposition of some other type of material.

The explanation would also have to account for the change in the terrain, from finely patterned on the right to more crystalline on the left.

Space Force puts a halt to the use of AI because of security issues

9:09 am

The Space Force has decided to stop using any artificial intelligence computer tools (AI) because of the security risks that presently risk in using them.

The Sept. 29 memorandum, addressed to the Guardian Workforce, the term for Space Force members, pauses the use of any government data on web-based generative AI tools, which can create text, images or other media from simple prompts. The memo says they “are not authorized” for use on government systems unless specifically approved.

Chatbots and tools like OpenAI’s ChatGPT have exploded in popularity. They make use of language models that are trained on vast amounts of data to predict and generate new text. Such LLMs have given birth to an entire generation of AI tools that can, for example, search through troves of documents, pull out key details and present them as coherent reports in a variety of linguistic styles.

Generative AI “will undoubtedly revolutionize our workforce and enhance Guardian’s ability to operate at speed,” Lisa Costa, Space Force’s chief technology and innovation officer, said in the memo. But Costa also cited concerns over cybersecurity, data handling and procurement requirements, saying that the adoption of AI and LLMs needs to be “responsible.”

This decision appears very wise. The insane fad in the last year to quickly adopt and even rely on AI has more than baffled me. Why are we in a such rush to let a robot do our for thinking and creative work for us? Have we become so lazy and dependent on computers that we’d rather let them do everything?

It is always dangerous to jump on a fad, without thought. That the Space Force has realized this is excellent news.

Long delayed and overbudget NASA satellite refueling mission expects more delays and further budget overruns

8:59 am

According to a new inspector general report, a long delayed and significantly overbudget NASA satellite refueling mission, dubbed OSAM-1 and first proposed around 2010, will experience more delays and further budget overruns in order to get it off the ground by 2026, at the earliest.

A NASA plan to robotically repair and refuel satellites in orbit is way behind schedule and well over budget, says NASA’s Office of the Inspector General (OIG), with most of the blame falling on space tech contractor Maxar.

Maxar, one of the largest private businesses working on NASA’s On-Orbit Servicing, Assembly, and Manufacturing mission (OSAM-1), has been involved in the project since 2016, when the space agency’s idea was smaller in scope and known as Restore-L. According to the OIG, Maxar is two years behind schedule on delivering the the project’s spacecraft bus and its Space Infrastructure Dexterous Robot (SPIDER) robotic arm, and it’s unlikely OSAM-1 will come in under its $2.05 billion budget nor meet the December 2026 launch date NASA committed to in 2022. The bus is the main craft framework, and its attached SPIDER will hopefully repair and refuel satellites in orbit, once it all gets off the ground and works.

NASA isn’t without blame for the delays, the OIG said, but Goddard Space Flight Center’s (the NASA facility where the project is being managed) “struggle with development of several key components of the servicing payload” wasn’t the main issue. “We found that project cost increases and schedule delays were primarily due to the poor performance of Maxar … and its inability to provide the spacecraft bus and SPIDER in accordance with contract requirements,” inspectors concluded in their report.

The plan has always been to refuel the Landsat-7 spacecraft in order to demonstrate robotic in-space servicing of satellites. When first proposed, the idea was untested, and the project was intended to get this industry off the ground. Since then however Northrop Grumman’s MEV servicing robot satellite has leap-frogged NASA to twice reactivate two geosynchronous satellites. At the same time, at least a half dozen other private startups have now done robotic rendezvous and docking demos in orbit, and have actual contracts for their own servicing missions.

Moreover, all the private missions have concepts that are far simplier and cheaper than NASA’s. Rather pump fuel into the defunct satellite’s tanks, the MEV simply docks with the satellite using its now useless main engine nozzle, and once attached becomes a service module with its own fuel and engines to orient and move the satellite. The other servicing startups are doing similar things. No need to develop complex robot arms and fueling systems.

In other words, private industry can learn little from this NASA’s mission. By the time it launches the industry will likely be able to run rings around it. It has become a waste of money that should be shut down, now.

India schedules Gaganyaan launch abort test for October 21st

8:40 am

India’s space agency ISRO has now scheduled the first unmanned launch abort test of its Gaganyaan manned capsule for October 21, 2023.

The test Crew Module (CM), according to the statement, will be akin to the pressurized module that’ll hold crew members during their ascent to space — this version, however, will be unpressurized. It will be launched via a single-stage liquid rocket specifically developed for this mission that will simulate an abort scenario; the true CM, by contrast, will ride atop a 143-foot-tall (43.5-meter) Launch Vehicle Mark-3 (LVM3) rocket with a solid stage, liquid stage and cryogenic stage. The latter recently received human safety certifications, R. Hutton, project director of the Gaganyaan mission, said during a conference last month.

At present ISRO is targeting 2024 for the first manned mission, but that target date remains very uncertain.

Launch of Psyche asteroid mission delayed by weather

8:36 am

NASA and SpaceX today scrubbed the launch of the Psyche asteroid mission because of poor weather, rescheduling the Falcon Heavy launch to tomorrow, October 13, 2023 at 10:19 am (Eastern).

“For our first backup window, Friday morning, 50% chance for go conditions, with our concerns still being associated with storms in the area, where we have anvil clouds, some thick clouds, which are layered clouds, as well as cumulus clouds we get associated with storms,” Moses explained during the briefing.

“Looking at Saturday morning, a third backup window, there is still about the same probability, about 50% chance of go, and fairly similar conditions here, where there may be some storms around, but we expect most of any storms to be after our morning launch window,” she added.

The launch window for the mission closes on October 25, after which a major mission rescheduling will be required to get the probe to the asteroid Psyche, likely causing a year delay.

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.

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.

Distorted Martian craters

Distorted Martian craters
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on March 15, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The white dot on the overview map above marks the location, on the west end of the 2,000-mile-long northern mid-latitude strip I label glacier country because almost every image suggests the presence of ice and glaciers.

Where this crater is located the terrain is shifting from mesas and criss-crossing canyons to the northern lowland plains. Thus, the features that suggest the presence of ice shift from glacial in nature (flowing down hollows and cliffsides or within canyons) to that of a near-surface ice sheet, which acts to distort impact craters and leave large splash aprons around them.

The straight depression cutting into the crater near the center top that is also aligned with craters to the southwest suggests that these craters are either sinkholes into a void created by a fault line, or the impacts all occurred at the same time, as the asteroid broke up while cutting through the Martian atmosphere.

Either could be true. The data is insufficient to determine which.

A nearby active galaxy, viewed head on by Hubble

9:39 am

Active galaxy
Click for original image.

Cool image time! The picture to the right, reduced and sharpened to post here, was taken by the Hubble Space Telescope and is the third of a seven-day celebration of galaxies by the Hubble science team. Previous images in the series can be found here. From the caption for this particular image:

At the center of NGC 6951 lies a supermassive black hole surrounded by a ring of stars, gas, and dust about 3,700 light-years across. This “circumnuclear ring” is between 1 and 1.5 billion years old and has been forming stars for most of that time. Scientists hypothesize that interstellar gas flows through the dense, starry bar of the galaxy to the circumnuclear ring, which supplies new material for star formation. Up to 40 percent of the mass in the ring comes from relatively new stars that are less than 100 million years old. Spiral lanes of dust, shown in dark orange, connect the center of the galaxy to its outer regions, contributing more material for future star formation.

This galaxy, located about 78 million light years away, has also seen six different supernovae in the past quarter century. Compare that with the Milky Way, which has not seen a supernova now in more than four hundred years.

Northrop Grumman abandons its own proposed space station; partners with Voyager’s Starlab

9:25 am

Northrop Grumman today officially confirmed rumors from earlier this week: It is abandoning construction of its own proposed space station and will instead join Voyager Space’s Starlab station project, using an upgraded version of its Cygnus freighter to be the station’s cargo ferry.

As part of this new partnership, Northrop will provide cargo services to Starlab for up to five years. The upgrades will allow Cygnus to dock directly to a station port, rather than rendezvous and get berthed using a robot arm. This upgrade will also make Cygnus a more saleable product for providing cargo to other stations as well, as they come on line.

Northrop Grumman was one of four proposed private space stations projects that won NASA contracts, Axiom in 2020 and the other three in December 2021, with its award fixed at $125.6 million, of which $36.6 million has been paid to the company for meeting specific development milestones. NASA is now going to distribute the rest of that award among the remaining projects after some renegotiations.

China to expand Tiangong space station

Tiangong-2 station after expansion

The new colonial movement: At the 47th International Astronautical Congress in Baku, Chinese officials yesterday revealed that they intend to expand their Tiangong space station, almost doubling it in size.

The graphic to the right illustrates this, with the proposed new modules in magenta at the top.

“We will build a 180 tons, six-module assembly in the future,” Zhang said. Tiangong currently has three modules, each with a mass of around 22 tons.

A multi-functional expansion module with six docking ports will first be launched in the coming years to allow this expansion. This will dock at the forward port of the Tianhe core module. Full size modules can then be added to Tiangong. SpaceNews understands that the timeline for such launches is around four years from now. An expanded Tiangong would be just over a third of the mass of the roughly 450-metric-ton International Space Station (ISS).

The officials also said that they plan to add additional inflatable modules to the existing part of the station, as well as attachment points allowing for external experiments exposed to the environment of space.

SpaceX successfully launches 22 Starlink satellites

10:57 pm

SpaceX tonight successfully launched another 22 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its eighth flight, landing on a drone ship in the Atlantic.

The leaders in the 2023 launch race:

70 SpaceX
45 China
13 Russia
7 Rocket Lab
7 India

American private enterprise now leads China in successful launches 81 to 45, and the entire world combined 81 to 72. SpaceX by itself trails the rest of the world (excluding American companies) by only 70 to 72.

SpaceX this year has now matched the record number of launches set by the U.S. in a single year that lasted from 1966 until last year. And it has done this with the year only 3/4s complete. Its goal of hundred launches this year is still well within reach.
