SpaceX announces launch time tomorrow for 3rd Superheavy/Starship launch

1:58 pm

UPDATE: The FAA has now amended [pdf] SpaceX’s launch license to approve tomorrow’s Superheavy/Starship launch.

Original post:
————————-
SpaceX has sent out email notices and now revised its Starship/Superheavy webpage to reflect a target launch time for the third Superheavy/Starship launch tomorrow, March 14, 2024, at 7 am (Central).

The third flight test of Starship is targeted to launch Thursday, March 14. The 110-minute test window opens at 7:00 a.m. CT.

A live webcast of the flight test will begin about 30 minutes before liftoff, which you can watch here and on X @SpaceX. As is the case with all developmental testing, the schedule is dynamic and likely to change, so be sure to stay tuned to our X account for updates.

I have not yet received a notice from the FAA, announcing the approval of a launch license, but SpaceX’s announcement likely signals that the approval has been given. As I noted yesterday, this approval was likely given as close to the launch as possible to help preclude any legal action by the various leftist activist groups that want to stop Elon Musk, stop SpaceX, and stop any grand human achievement. Their dislike and alienation with success is so deep that such tactics are now necessary to stymie them and allow such achievements to proceed.

A youtube live stream will also be available here. If the flight succeeds in getting Starship into orbit, it will attempt to open and close its payload door, attempt a propellant transfer test, and then attempt the first in-space relight of a Raptor engine in order to bring it down controlled in the Indian Ocean.

Scientists: Mars’ mysterious slope streaks and seasonal recurring lineae are caused by dust

1:08 pm

Massive flow on Mars
A typical Martian slope streak.

On Mars there are two mysterious features that are somewhat similar but entirely unique to the Red Planet, and for years have baffled planetary geologists as to their origins.

One feature is called slope streaks, which appear randomly year-round as either dark or bright streaks on slopes. They resemble avalanches, except that they do not change the topography, have no debris piles at their base, and sometimes travel along that topography, sometimes even going uphill for short distances. Over time these streaks then fade.

The other feature is called recurring slope lineae, because though they look like slope streaks, they are not random but appear seasonally at the same places each year. Lineae are also always dark.

Scientists have proposed many theories to explain both, with most theories involving some form of water process, either the seepage of brine from below or water vapor causing the Martian surface dust to flow, like droplets on a car windshield. None of these theories has been confirmed, or entirely accepted.

Two studies at this week’s 55th annual Lunar and Planetary Science Conference in Texas have both concluded that water is not a factor in the formation of either phenomenon. Instead, both papers propose a much simpler explanation: Wind and blowing dust interact to cause small dust avalanches.

Lucy’s first encounter with an asteroid produced surprises

12:39 pm

Dinkinesh, with Salam

At the 55th annual Lunar and Planetary Science Conference presently being held in Texas, the science team for the Lucy asteroid mission presented their first papers outlining what they learned during the spacecraft’s first asteroid encounter, flying past the main belt asteroid Dinkinesh on November 1, 2023.

To the right is the the best image taken at closest approach, at about 270 miles distance, annotated to include the analysis of Dinkinesh’s shape by scientists. As noted in the summary paper [pdf], the asteroid is about a half mile in diameter, and appears to have an equatorial ridge, similar to the ridges found on the near-Earth rubble-pile asteroids Bennu or Ryugu. Dinkinesh is not a rubble pile, however. Though boulder-strewn, it appears more solid, and even has what the scientists call a longitudinal trough, as indicated in the picture.

The ridge overlays the trough implying that it is the younger of the two structures. However, there is as yet no information to better constrain their relative ages, and thus they could potentially have formed in the same event. Indeed, Dinkinesh’s ridge and trough are likely the result of mass failure and the reaccretion of material, and may both be linked to the formation of Selam.

That flyby had produced one major surprise, the existence of a smaller satellite asteroid orbiting Dinkinesh, now dubbed Selam. It is shown in the lower left, as it appeared from behind the main asteroid as Lucy flew past. A later picture however revealed an even greater surprise.

This week the 55th annual Lunar and Planetary Science Conference is being held in Texas. The conference was originally established in connection with the Apollo missions to allow scientists to release their Moon research results. It quickly morphed into an annual event covering research from the entire planetary research community.

I have reviewed the abstracts for this year’s meeting, and culled what I think are the most significant new results from the conference, which I will report on in the next few posts.

We begin however with possibly the most important result from the conference, given by the science team for the ShadowCam instrument on South Korea’s Danuri lunar orbiter. That low-light camera was designed to take high resolution pictures of the permanently-shadowed craters of the Moon, to see if there was any visible or obvious ice hidden there. Though the science team presented a number of papers, the summary paper [pdf] by the instrument’s principal investigator, Mark Robinson of Arizona State University, gave the bottom line:

The data so far is finding very little evidence of water ice in these dark regions.

The investors behind Space One, the Japanese commercial rocket company that had a launch failure yesterday

9:01 am

The explosion yesterday of the new Japanese-built Kairos-1 solid-fueded rocket shortly after lift-off immediately raised questions whether the new rocket company that built it, Space One, could survive that failure.

This story from CNBC suggests it will, based mainly on the nature of its principal investors.

Space One was set up in 2018 by a consortium of Japanese companies including Canon Electronics, IHI Aerospace and construction firm Shimizu, along with the government-owned Development Bank of Japan. Mitsubishi UFJ and Mizuho Financial Group, two of Japan’s biggest banks, also own minority stakes in Space One.

The story is focused on the declines in the stock values of these companies, following the failure, with Canon’s stock falling the most, 12.7%.

My takeaways from the article however are different. First, these are not small investors. Space One is backed by some of Japan’s biggest corporations as well as indirectly by the Japanese government. One failure should not cause them to back out of the project.

Second, that the company was formed in 2018 by these Japanese heavy-hitters and only now was able to finally attempt a launch — that ended in failure — suggests Japan’s heavy-hitters continue to do things slowly and poorly. Not only have these big companies been working much too slow to build this relatively small rocket, Mitsubishi’s effort to build the much larger H3 rocket for Japan’s space agency JAXA has also been fraught with delays and problems, from engine cracks to launch failures. It appears Japan’s space industry is building things with the same lackadaisical attitude of America’s modern airline industry.

Third, that this “startup” was created by a team of old space large companies suggests Japan still doesn’t get the basics of capitalism. This new company isn’t creating any real competition. It was instead apparently formed to keep these heavy hitters in control of the Japanese launch market. This partnership reminds me of the many projects put together for decades by American consortiums of old space companies, such as Boeing teaming with Lockheed Martin to create ULA. All such partnerships were designed not to create new companies and new innovative products that would compete, but to maintain the control these old companies had on the industry.

Space One will likely fly again, but until we begin to see completely new companies from Japan, backed by independent new investors, this country is going to continue to lag behind everyone else.

First launch of Japanese rocket startup fails

10:03 pm

The first launch attempt by the Japanese rocket startup Space One failed today, when its Kairos-1 rocket blew up mere seconds after launch.

The launch took place from the company’s own launchpad in the south of Japan. The live stream shows the rocket appear to lift off cleanly, moving upward out of frame. When the video then switches camera to a more distant view, the rocket fails to appear from behind a nearby hill. Instead, a white cloud explodes upward. Shortly thereafter the live stream switches back to the launchpad, where there is a fire and smoke. Fire hoses then begin working to put the fire out.

Space One is the first independent commercial rocket startup in Japan apparently not working with that country’s JAXA space agency. We will have to wait and see whether it can recover from this failure.

A Martian tadpole

Overview map

A Martian tadpole
Click for original image.

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

The white dot on the overview map above marks the location, with the rectangle in the inset marking the area covered by the picture. The science team labels this “inverted features,” a more vague way to describe the feature geologists dub “inverted channels.” The flow of a river or glacier acts to harden and increase the density of the channel bed. Later, the water or ice disappears, leaving just the canyon.

Even later, erosion begins to wear away the surrounding terrain. Because the canyon floor is now harder than that surrounding terrain, that floor is more resistent to erosion, and eventually becomes ridge following the exact same path as the long gone river or glacier.

This is what we have here, with this inverted channel, which is about five miles long, once draining into the deeper eroded valley to the south.

The location is at 38 degrees north latitude and inside the 2,000-mile-long mid-latitude region I dub glacier country, because almost every image shows evidence of glaciers or ice flows on the surface. This picture however is a rare exception. The features in this picture instead appear to be bedrock, something that is rarely seen in the canyons and craters in glacier country. It is beyond my pay grade however to explain why this spot lacks such features. Or it could be the near surface ice here looks so much like bedrock I am misinterpreting the picture.

FAA lists possible launch windows for Starship/Superheavy launch

11:59 am

Though it as yet not issued a launch permit, the FAA has now released an advisory to the public, listing the possible launch windows for the next Starship/Superheavy launch, beginning on March 14, 2024 and including windows on each day through March 18th.

The advisory lists a primary date of Thursday, March 14, with the time 12:00Z-14:13Z (7 a.m. to 9:13 a.m. central). The plan also includes backup dates for the following four days, with the window closing at 8:01 a.m. on Saturday and Sunday before increasing to 9:13 a.m. again on Monday.

It is very possible this advisory is premature. It does strongly suggest however that the FAA is about to issue the launch licence. Based on past actions, expect that license to be announced as close to the launch date as reasonably possible, in order to make difficult or impossible any legal action to stop it by the various independent activist groups that have been suing both SpaceX and the FAA. (While the FAA has clearly been ordered by higher-ups in the Biden administration to slow-walk SpaceX’s effort, its people generally want SpaceX to succeed.)

If the first launch attempt will be on March 14th, two days hence, that license licence must be issued soon.

Sunspot update: The Sun continues what appears will be a weak maximum

10:30 am

As I have done each month since 2011, I am now posting an annotated version of NOAA’s monthly graph, tracking the solar sunspot activity on the Earth-facing hemisphere of the Sun. The NOAA updated graph was posted at the start of March, covering activity through the end of February, so this report is a little later than normal.

That graph is below. In February sunspot activity remained essentially steady, only slightly higher than the activity from the month before. Those numbers also hovered at about the same level seen since August 2023.

Rocket startup Phantom Space completes another investment capital funding round

8:59 am

The Tucson-based rocket startup Phantom Space has successfully completed another investment capital funding round, bringing the total funding it has raised to $37 million.

Balerion Space Ventures led the round, which also included participation from the Reaser Family Office, KOLH Capital, and a handful of existing and new investors.

The company hopes to do its first test launch of its Daytona rocket next year, lifting off from Vandenberg. The article at the link says the launch permits from Vandenberg have been obtained, but as of about a month ago my sources said the company was still awaiting approvals from various agencies.

ISS crew splashes down safely

8:50 am

SpaceX’s Endurance manned capsule yesterday safely splashed down in the Gulf of Mexico, bringing home a crew of four astronauts from ISS after completing a six month mission.

NASA astronaut Jasmin Moghbeli, ESA (European Space Agency) astronaut Andreas Mogensen, JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov, returned to Earth splashing down at 5:47 a.m. EDT. Teams aboard SpaceX recovery vessels retrieved the spacecraft and its crew. After returning to shore, the crew will fly to NASA’s Johnson Space Center in Houston.

…Moghbeli, Mogensen, Furukawa, and Borisov traveled 84,434,094 miles during their mission, spent 197 days aboard the space station, and completed 3,184 orbits around Earth. The Crew-7 mission was the first spaceflight for Moghbeli and Borisov. Mogensen has logged 209 days in space over his two flights, and Furukawa has logged 366 days in space over his two flights.

This was the third flight of Endurance. As always, it is important to note that though the passengers were government employees from the U.S., Europe, Japan, and Russia, the entire splashdown crew and capsule were private employees of SpaceX. This was a private mission, purchased by those governments.

The strange surface of the perennial dry ice cap at Mars’ south pole

4:40 pm

The strange surface of Mars' dry ice cap
Click for original image.

Cool image time! The picture to the right, cropped to post here, was taken on January 24, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a region about 180 miles from the south pole of Mars.

This terrain is intriguing because is the pattern of ridges that cover it entirely. I have simply cropped the original image to show these ridges in highest resolution. The full image shows them covering a region much larger than this.

What are we looking at? Because it is near the pole, it is likely that the black splotches are caused by carbon dioxide gas breaking through the winter mantle of dry ice that covers the poles during the winter months and then sublimates away, from the bottom, each spring. As the dry ice turns to CO2 gas that gas is trapped, until it can find a weak spot in the overlying mantle. When the pressure builds enough, the mantle breaks, the gas escapes, and as it does so it deposits the dark dust around the breakage. That dust fades as the mantle disappears.

Sounds good, eh? Not so fast.

Hubble and Webb confirm decade-long conflict in universe’s expansion rate

8:58 am

The uncertainty of science: New data from both the Hubble and Webb space telescopes has confirmed Hubble’s previous measurement of the rate of the Hubble constant, the rate in which the universe is expanding. The problem is that these numbers still differ significantly from the expansion rate determined by the observations of the cosmic microwave background by the Planck space telescope.

Hubble and Webb come up with a rate of expansion 73 km/s/Mpc, while Planck found an expansion rate of 67 km/s/Mpc. Though this difference appears small, the scientists in both groups claim their margin of error is much smaller than that difference, which means both can’t be right.

You can read the paper for these new results here.

The bottom line mystery remains: The data is clearly telling us one of two things: 1) the many assumptions that go into these numbers might be incorrect, explaining the difference, or 2) there is something fundamentally wrong about the Big Bang theory that cosmologists have been promoting for more than a half century as the only explanation for the formation of the universe.

The solution could also be a combination of both. Our data and our theories are wrong.

Two SpaceX launches yesterday evening, on opposite coasts and only five hours apart

8:39 am

SpaceX yesterday completed two different Starlink launches, placing 46 satellites total into orbit from opposite coasts and only five hours apart.

First, at 7:05 pm (Eastern) a Falcon 9 rocket lifted off from Cape Canaveral, carrying 23 Starlink satellites, with its the first stage successfully completing its seventeenth flight.

Next, just over five hours later, a Falcon 9 rocket lifted off from Vandenberg, carrying its own cargo of 23 Starlink satellites, with its first stage also completing its seventeenth flight.

The leaders in the 2024 launch race:

24 SpaceX
10 China
3 Russia

American private enterprise now leads the rest of the world in successful launches 27 to 19. SpaceX by itself now leads the entire world, including other American companies, 24 to 22.

Stratolaunch completes first flight of its Talon-A hypersonic test vehicle

8:50 pm

Stratolaunch yesterday successfully completed the first flight of its Talon-A hypersonic test vehicle, released from its giant Roc airplane.

Primary objectives for the flight test included accomplishing safe air-launch release of the TA-1 vehicle, engine ignition, acceleration, sustained climb in altitude, and a controlled water landing.

“While I can’t share the specific altitude and speed TA-1 reached due to proprietary agreements with our customers, we are pleased to share that in addition to meeting all primary and customer objectives of the flight, we reached high supersonic speeds approaching Mach 5 and collected a great amount of data at an incredible value to our customers,” said [Dr. Zachary Krevor President and CEO of Stratolaunch]. “Our goal with this flight was to continue our risk reduction approach for TA-2’s first reusable flight and be steadfast on our commitment of delivering maximum value to our customers. We are excited to review the data from today’s test and use it as we plan our next steps toward TA-2’s first flight later this year.”

Stratolaunch’s main customer is the Air Force, which wishes to use this testbed to test hypersonic flight in a number of ways, both for missiles and possibly aircraft. Those military goals explain the required secrecy.

Stratolaunch is under competitive pressure from Rocket Lab, which has already demonstrated that the first stage of its Electron rocket can provide a similar testbed. Stratolaunch is reusable, however, which potentially makes it cheaper with a faster turnaround. Rocket Lab in turn is already capable of test flights. This Stratolaunch success will likely spur Rocket Lab to complete its program to recover and reuse those first stages, while Rocket Lab’s succes is likely spurring Stratolaunch to accelerate its own program.

Ain’t competition wonderful?

Japanese rocket startup scrubs first launch attempt

9:11 am

The first Japanese rocket commercial rocket company, Space One, today scrubbed the first launch attempt of its Kairos rocket, scheduled to take off from its own launchpad in the south of Japan.

“We informed the public in advance that we wanted to make the area free of people, but even 10 minutes before the launch, a vessel remained in the area, so we decided to cancel the launch because it would have been impossible for them to leave promptly,” Space One executive Kozo Abe told a news conference in the afternoon.

Abe said there were no technical problems with the launch and that the next attempt could come as soon as Wednesday, with the company likely to give a more detailed schedule at least two days before the new date.

The rocket has four-stages, the first three solid-fueled and the last liquid-fueled. Its capacity is comparable to Rocket Lab’s Electron rocket, and the company hopes to eventually ramp up to as many as twenty launches per year.

First manned Starliner mission slips to May

8:53 am

The first manned mission of Boeing’s Starliner capsule has now been delayed another few weeks, to early May, due to scheduling conflicts at ISS.

The delay was revealed as an aside in a NASA press release detailing the schedule of press briefings related to the mission. There appears to be no technical reasons for the delay. The quiet way NASA revealed it probably just indicates the agency’s embarrassment at Boeing’s overall problems with this spacecraft that have caused a four year delay in its first manned mission.

The flight will dock with ISS, last two weeks, and carry two astronauts, Butch Wilmore and Suni Williams. Its goal is to complete the final check out of Starliner prior to the initiation of operational missions. Once done, Boeing will not only begin to fly paid flights to ISS for NASA, it will be free to offer this capsule to others, including commercial tourists. Don’t expect customers to flock to buy seats, considering the many problems both Boeing and Starliner have had. Instead, it will likely take Boeing several years of NASA missions to reassure customers the spacecraft is reliable.

Update on rocket startup Stoke Space’s effort to make completely reusable rocket

10:07 am

Link here. This Nasaspaceflight.com article provides an excellent update on the status of the development of Stoke’s Nova rocket, which will have a radical new engine design in its upper stage, using a ring of small nozzles rather than one single central one. That design will allow the upper stage to return to Earth for reuse, something that no other rocket now in use at present can do.

Stoke Space recently carried out the first test of the full-size 30-thruster version of the innovative engine that the company is producing for its in-development second stage. This will be an integral part of its future Nova rocket, which aims to be a fully reusable medium lifter.

The engine test took place on Feb. 26 and follows the engine’s first test flight on its prototype vehicle, Hopper 2, in September 2023. Although fitted with only 15 chambers for that flight, Hopper 2 flew for 15 seconds, achieved a maximum altitude of 30 feet, traversed to a landing site, and touched down softly.

The article includes a lot of interesting technical details about this upper stage and what engineers are learning about this radical engine design. Worth reading. At present Stoke is the only company other than SpaceX attempting to make its upper stage fully reusable. If successful it will jump ahead of everyone else.

No launch schedule however for its new rocket was revealed in this report, so it might be awhile, if ever, before any of this bears fruit.

Budget bill includes very short extension of commercial space “learning period”

9:39 am

The budget bill that Congress has just passed and awaits signature by the president included a very short extension of commercial space “learning period” that supposedly prevents heavy safety regulation by the FAA of the new commercial space industry.

That learning period was first established in 2004, and has been extended several times since. This new bill extends that period until May 11, 2024, only two months, supposedly to allow Congress time to pass a new commercial space act.

The truth is that, at present, the Biden administration has long since abandoned that learning period exemption, and has been applying a much stricter safety regulatory framework from space companies than required by law, as best illustrated by its treatment of SpaceX’s Superheavy/Starship launches. The FAA now expects all launches to function perfectly, even if testing a prototype, and should anything not go perfectly it treats the failure the same as an airplane mishap that requres any investigation to get full government approval before further launches can resume.

Unless there is a change in leadership in Washington, it is very likely we shall see few new American rocket companies from here on out. The existing companies with lots of money and power will survive, but under this heavy regulatory atmosphere it will be hard if not impossible for new companies to get established.

Astra’s board agrees to deal to take the company private

9:24 am

The board of directors of the rocket startup Astra have finally agreed to a cut-right price offer from the company’s two founders to buy the company and take it private once again, rather than declare bankruptcy.

The company announced Thursday that its board had accepted an offer from its CEO, Chris Kemp, and its CTO, Adam London, to purchase the remaining Astra stock at a price of $0.50 per share. The deal is expected to close in the second quarter of 2024, at which time Astra will cease trading on the Nasdaq.

This offer was significantly less than their first offer in November, when Kemp and London offered to buy the company for $1.50 per share, suggesting the company’s value has declined significantly in the interim as its cash assets declined. This decline suggests that any recovery will be difficult and long, and could easily fail.

Freedom is wonderful in that it allows for the greatest amount of creativity, competition, and achievement, from everyone. It also carries great risk that everyone must face. Astra has now illustrated the risk. Not all creative gambles are going to succeed.

Sierra Space confirms its Tenacity spacecraft successfully completed vibration testing

9:16 am

Sierra Space yesterday confirmed that its first Dream Chaser reusable mini-shuttle Tenacity, being readied for a hoped-for April launch, successfully completed vibration testing last month.

Key accomplishments in this first critical phase of pre-flight testing included: the completion of Sine Vibration Testing (in all three axes or directions), a Separation Shock Test that simulates the separation of the Dream Chaser from Shooting Star and a test that involved deploying the spaceplane’s wings. These tests evaluated Dream Chaser’s performance under the stresses of launch, operation in orbit and ability to communicate with the International Space Station (ISS).

What I find revealing about the press release at the link is that it really adds nothing from a NASA press release from a month ago. Then NASA said that Tenacity was about to move to a vacuum chamber for environmental testing. According to this new press release, that move has still not occurred and the environmental test still must begin.

That engineers didn’t move Tenacity to environmental testing while they were reviewing the vibration test data suggests there was something in that test data that prevented it. It appears that unstated issue is resolved, but it caused a pause in testing.

As a result, it appears that an April launch is unlikely delayed by a month or more, assuming my attempt to read between the lines is correct.

The really really strange landscape of Cydonia on Mars

Some really strange terrain on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on January 3, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows what the camera team describes merely as “landforms.”

In truth, these features, as well as almost everything in the surrounding terrain beyond the edge of this picture, are possibly the weirdest geological features on Mars. The two mounds, no more than fifteen feet high at the most, resemble pimples. The rough ground to the north actually appears to be some flow that worked its way around the mounds, as indicated by the arrows. The crack to the southeast of the two mounds appears to be an extension of a fault line that cuts through the center of the larger mound, suggesting the mound is some form of eruption belching out of that fissure.

That the latitude is 42 degrees north, these weird features all suggest some form of ice-based volcanic activity, because the ground here is probably impregnated with ice.

As for the bridge connecting the two mounds, who knows what caused it?

Another woman sues SpaceX for sexual discrimination and retaliation

10:10 am

On March 5, 2024 Michelle Dopak filed a lawsuit against SpaceX for sexual discrimination and retaliation, claiming the company paid her less than male workers, refused to promote her, and ignored her complaints about sexual abuse by her married manager that eventually led to a pregnancy.

Dopak said in the suit that in 2020, her manager offered her $100,000 to have an abortion, which she declined. She is suing the company for an unspecified amount of damages. Reuters was first to report the existence of the lawsuit. Dopak accused SpaceX of colluding with her former manager by allowing him to transfer $3.7 million in SpaceX stock out of his name to evade child support payments, according to the lawsuit obtained by Business Insider.

This suit is one now of several discrimination suits against the company. Unlike the others, however, if Dopak’s accusations prove true it would be the most damaging of all, since she claims the company itself took action against her to protect this manager. The other suits appear more frivolous on their face, issued by individuals claiming to have been fired by SpaceX for their opinions, when the facts strongly suggest they were more interested in causing trouble at the company then doing their job, and thus deserved to be fired.

NJ man arrested for trafficking 675 Starlink terminals illegally

10:00 am

A New Jersey man was arrested on December 4, 2023 while driving a vehicle carrying more than two hundred Starlink terminals, and later charged with trafficking 675 Starlink terminals that he obtained illegally using “stolen credit card accounts or hacked Starlink billing accounts.”

The man, 35-year-old Kelvin Rodriguez-Moya, was stopped by police Dec. 4 while driving 223 Starlink terminals in a pickup truck and trailer after leaving a residence in Lawrence Township, New Jersey, a criminal complaint said. The terminals had shipping labels addressed to multiple different names at the same address.

Lawrence Township police had been tipped off about a suspiciously large number of Starlink terminals being shipped to that home, the complaint said. Detectives then witnessed Rodriguez-Moya loading a FedEx shipment of terminals onto the truck and trailer.

SpaceX is working with the police to determine how Rodriguez-Moya obtained so many terminals. I suspect it was because so much of Starlink operations are automated. The computer programs that issue terminals to new customers aren’t smart enough to notice such things.

This case might also help explain the stories in both Russia and Botswana of unauthorized terminals being sold.

Blue Origin completes first round of launchpad/New Glenn tanking tests

9:52 am

Link here. In the past week or so Blue Origin has done three tanking tests of its assembled engineering test rocket, simulating fueling of a New Glenn rocket on the launchpad, and now intends to roll that test vehicle back to its rocket assembly building.

From here, it is most likely that the rocket will be prepared for the next round of testing, which will include a static fire of the seven first-stage BE-4 engines. This test will mark the first time that Blue Origin’s BE-4 engines will ignite while integrated with a New Glenn first stage. It will also be the first time that the new launch pad supports an engine firing.

The company continues to aim for a first test launch of New Glenn before the end of the year, and these tests strengthen the likelihood that this schedule is realistic.

UK government to invest £10 million in Saxavord spaceport

9:45 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea.

The government of the United Kingdom announced yesterday that it will directly invest £10 million in the Saxavord spaceport being built on one of the Shetland Islands, as shown on the map to the right.

Coming in addition to around £40 million of private investment, the government funding will allow SaxaVord to accelerate its capital works programme to ensure it is ready to support the first orbital launch.

That capital works program was forced to shut down last year when red tape at the Civil Aviation Authority (CAA) delayed the licensing of Saxavord. It could be this grant has been issued partly to repay the losses the spaceport company experienced due to those bureaucratic delays. The timing kind of reinforces this speculation, as only yesterday Saxavord got its spaceport license approved, though other approvals remain pending.

All this news suggests strongly that the first test flight at Saxavord by the German rocket startup Rocket Factory Augsburg will occur later this year, as promised.

Meanwhile, the other spaceport in Sutherland must be wondering if it can get similar government aid, or if the government is now playing favorites.

SpaceX: We want to fly next Starship/Superheavy test launch on March 14, 2024

9:07 am

In a tweet yesterday SpaceX announced an update on its Starship webpage, outlining its plans for the third orbital test launch of its heavy-lift Starship/Superheavy rocket, with March 14, 2024 listed as the hoped-for launch date.

The update began with these cautionary words, “pending regulatory approval,” and then went on to describe details of the test flight:

The third flight test aims to build on what we’ve learned from previous flights while attempting a number of ambitious objectives, including the successful ascent burn of both stages, opening and closing Starship’s payload door, a propellant transfer demonstration during the upper stage’s coast phase, the first ever re-light of a Raptor engine while in space, and a controlled reentry of Starship. It will also fly a new trajectory, with Starship targeted to splashdown in the Indian Ocean. This new flight path enables us to attempt new techniques like in-space engine burns while maximizing public safety.

I suspect the change in the splashdown location, from northeast of the main island of Hawaii, was instigated by the FAA for those “public safety reasons”. From SpaceX’s perspective, this is an easy give, as a slightly shorter flight makes little difference for this test, and it allows the company to test that Raptor engine by firing that de-orbit burn.

Will the flight occur on March 14th? The odds are high, partly because this SpaceX announcement is designed to put pressure on the bureaucrats at the FAA to finish their paperwork already. At the same time, bureaucrats sometimes love to stick it to private citizens, just for fun. We shall see.

Is this really a spiral galaxy?

Is this really a spiral galaxy?

The uncertainty of science: The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope and released on March 4, 2024 by the PR department of the European Space Agency (ESA) as part of its Hubble Picture of the Week program. It shows what the press release claims is a spiral galaxy about 55 million light years away, seen edge on.

In this image NGC 4423 appears to have quite an irregular, tubular form, so it might be surprising to find out that it is in fact a spiral galaxy. Knowing this, we can make out the denser central bulge of the galaxy, and the less crowded surrounding disc (the part that comprises the spiral arms).

If NGC 4423 were viewed face-on it would resemble the shape that we most associate with spiral galaxies: the spectacular curving arms sweeping out from a bright centre, interspersed with dimmer, darker, less populated regions. But when observing the skies we are constrained by the relative alignments between Earth and the objects that we are observing: we cannot simply reposition Earth so that we can get a better face-on view of NGC 4423!

This picture provides a great example of the amount of assumptions that are often contained in astronomical observations. Though the data strongly suggests this is spiral, we must remember this is merely an educated guess, based on that central bulge and the dust lanes visible along the galaxy’s profile. There is actually no guarantee that this is so. As the press release also notes, astronomers are constrained by our viewpoint, and cannot change that viewpoint to get a better view to confirm this guess. For all we know, a face on veiw of this flat galaxy would reveal it has no spiral arms, but instead is mottled and chaotic, a rare type that does exist.

Astronomers do the best they can, but it is important that they (and we) always recognize the limitations.

More orbital tugs reach orbit

9:44 am

When SpaceX launches a large number of smallsats and payloads on a Falcon 9 launch, as it did on March 5 from Vandenberg in California, it routinely takes several days or even months for the results from each payload or smallsat to trickle in. Two reports today illustrate the growing cottage industry of orbital tugs.

First, a company named Apex has successfuly demonstrated its first service module for satellites, designed to provide the basic services needed for satellites so that companies can focus on designing their primary mission rather than reinventing a basic satellite each time. The module was launched on March 5th, and has been operating as expected. The company hopes to begin mass producing this service module in a new factory later this year.

Second, a new orbital tug company from France, Exotrail, has successfully deployed a cubesat from its first tug. That tug was launched on a Falcon 9 smallsat launch in November, and has been testing operations since. After releasing that cubesat for Airbus’s defense division, the tug is continuing operations, acting as the service module for a second payload from Belgium that is testing its own gyros and reaction wheels for controling smallsat orientation.

These companies are small, and are focused on very specific technologies needed by smallsats to operate efficiently in space. As such, their achievements are generally more mundane and less exciting that a SpaceX Starship/Superheavy test launch, by many magnitudes. Nonetheless, their success, not only technically but financially, suggests a growing maturity to the in-orbit space industry, which will also lay the groundwork for much more sophisticated operations in the future beyond Earth orbit. The people that build these tugs will move on to build vessels that can go to the planets and do things that are presently impossible or too difficult, and do it at low cost and very quickly.
