The new town of Starbase is canceling its May elections

12:15 pm

Boy, Elon Musk sure is a FASCIST! Because no one filed to run against the mayor and two commissioners, the new town of Starbase is now about to cancel its May elections.

During an upcoming meeting, the Starbase City Commission is scheduled to consider an ordinance canceling the May 2, 2026 General Election, as all candidates for mayor and city commissioner are running unopposed.

Under Texas law, local governments may cancel elections when every race on the ballot is uncontested.

That means Starbase’s current leadership will remain in office without voters needing to cast ballots. The city’s inaugural mayor is Robert “Bobby” Peden, a SpaceX executive who serves as Vice President of Texas Test and Launch for the company. Two commissioners serve alongside him: Jordan Buss, a senior director of environmental health and safety at SpaceX, and Lois Wallace, an interim commissioner and Starbase resident.

Expect to see stupid mainstream stories suggesting no one filed because people were afraid to run against these SpaceX managers and thus threaten their job status. “Musk, that evil fascist, clearly threatened to send out hit men against anyone who filed! Opposition to Musk will not be allowed!”

What I think is really happening is twofold. First, no one at SpaceX is really interested in this boring administrative government work. They’d rather build cutting-edge rockets. Note that the two commissioners are not really rocket engineers, with one being the wife of a SpaceX employee and the other doing “environmental health and safety” work, likely related to making sure SpaceX meets government work regulations. The real engineers at SpaceX have better things to do.

Second, there really isn’t that much for these town officials to do anyway. The town was established mostly to ease SpaceX’s own regulatory red tape with the state, and once established the task is largely done. Why waste time running for a position that will only add to your work load, while accomplishing nothing of real substance?

A day-by-day description of the entire Artemis-2 manned mission

10:04 am

NASA today posted a detailed day-by-day description of the entire ten-day Artemis-2 manned mission around the Moon, outlining the tasks planned for the astronauts on each day.

The launch is now targeting April 1, 2026.

The description of their closest approach to the Moon is both interesting and underwhelming.

The Artemis II crew will come their closest to the Moon on flight day 6, while traveling the farthest from Earth. Artemis II could set a record for the farthest anyone has traveled from Earth depending on launch day, breaking the current record – 248,655 miles away – set in 1970 by the Apollo 13 crew. The distance the Artemis II crew will travel depends on their exact launch day and time.

Over the course of the day, the crew will come within 4,000 to 6,000 miles of the lunar surface as they swing around the far side of the Moon – it should look to them about the size of a basketball held at arm’s length. [emphasis mine]

In other words, Orion is not going to get very close, and in fact, the Moon will only be 2 to 3 times bigger than what we see here on Earth. I suspect the best photographs taken will be those showing both the Earth and Moon, both of which will be relatively small.

Overall, I remain highly concerned about this mission. The life support system has never been tested in space before, and they will spend the first day checking it out in Earth orbit. And the return to Earth will involve using a heat shield that did not perform well on the Artemis-1 mission in 2022, losing chunks during re-entry.

They hope a less stressful flight path will mitigate this issue, but then, they need to hit that flight path perfectly on their way back from the Moon. During yesterday’s briefing it was obvious this was a concern to NASA officials.

China to begin construction of its Mars sample return spacecraft

8:13 am

China’s state-run press today announced it is about to begin construction of its Mars sample return spacecraft, Tianwen-3, set for launch in 2028.

Based on the announcement, that date seems very unlikely.

China’s mission to retrieve samples from Mars will advance to the flight model development phase within this year, Liu Jizhong, chief designer of the Tianwen-3 mission, said on Thursday. Building on the preliminary technical research and demonstrations, the mission has achieved breakthroughs in key technologies. The engineering team is now focused on developing prototypes, Liu, also a national legislator, told reporters.

The Mars sample return mission is scheduled for launch around 2028, with the goal of returning no less than 500 grams of Martian samples to Earth by around 2031. [emphasis mine]

They only have two years to get the spacecraft built, and it involves “an orbiter, a returner, a lander, an ascender, and a service module.” While China is basing this mission’s design on its successful Chang’e lunar sample return missions, returning samples from Mars is significantly more challenging. The ascent vehicle will have a much greater gravity to overcome, and doing a robotic rendezvous and docking in orbit around another planet millions of miles from Earth has never even been tried.

German rocket startup Isar Aerospace wins launch contract from Astroscale

8:03 am

Proposed or active spaceports in North Europe
Proposed or active spaceports in North Europe

The German rocket startup Isar Aerospace has won a launch contract using its Spectrum rocket to launch Astroscale’s ELSA-M space junk removal mission, with a launch now targeting 2028.

The mission involves a $15 million contract Astroscale won from the space agencies of the UK and Europe to de-orbit a defunct OneWeb satellite. This demo mission however has been delayed repeatedly since it was first announced in 2022. Then it had a launch date of 2024. In 2024 that launch date was shifted to 2026. With this new announcement it is delayed again, to 2028.

Isar meanwhile has not yet achieved a successful launch of its Spectrum rocket. The first attempt, in March 2025, failed mere seconds after launch due to a loss of attitude control. Its second attempt is presently scheduled for March 19 from Norway’s Andoya spaceport.

If successful, this launch would be the first from a European spaceport, and the first from one of Europe’s new rocket startups.

China completes two launches early today

7:40 am

China early today resumed launches after a month-long pause, apparently for the Chinese New Year.

First, it completed the 20th launch for the Guowang (Satnet) internet satellite constellation, its Long March 8A rocket lifting off from its coastal Wencheng spaceport.

Though China’s state-run press provided no information on the number of satellites in the payload, all previous launches using the Long March 8A had carried nine satellites. If so, that would mean the constellation now has 159 satellites in orbit, out of a planned 13,000.

Next, China placed two “test satellites” into orbit, its Long March 2D rocket lifting off from its Xichang spaceport in southwest China. Its state-run press provided no information about where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China.

The leaders in the 2026 launch race:

30 SpaceX
10 China
3 Rocket Lab
2 Russia

SpaceX continues to lead the entire world combined in total launches, as it did in both ’24 and ’25. Though it has up to now almost doubled the launch pace of everyone else, with China resuming launches that pace will likely end.

Cubesat ultraviolet space telescope achieves first light

5:05 pm

Sparcs first light images
Click for original images.

A new low-cost cubesat-sized NASA ultraviolet space telescope, dubbed Sparcs, has achieved first light, successfully taking both near- and far-ultraviolet false-color images of a nearby star.

Those images are to the right, with the top the far-ultraviolet image and the bottom in the near ultraviolet. From the press release:

Roughly the size of a large cereal box, SPARCS will monitor flares and sunspot activity on low-mass stars — objects only 30% to 70% the mass of the Sun. These stars are among the most common in the Milky Way and host the majority of the galaxy’s roughly 50 billion habitable-zone terrestrial planets, which are rocky worlds close enough to their stars for temperatures that could allow liquid water and potentially support life.

The question astronomers will try to answer with this telescope is whether the solar activity on these stars is high enough to prevent life from forming in the star’s habitable zone. Because these stars are dim and small, the habitable zone is quite close to the star, which means solar activity has a higher impact on the planet. We don’t yet have sufficient data to determine the normal activity of such stars. Sparcs will provide a good first survey.

It will also demonstrate the viability of such small low-cost cubesats for this kind of research. If successful expect more such telescopes, some of which are likely to be private, like Blue Skies Space’s Mauve optical telescope already in orbit.

NASA now targeting an April 1st launch of Artemis-2

3:54 pm

At a press briefing today, NASA officials said they are now targeting an April 1, 2026 launch date for the Artemis-2 mission, a ten-day manned mission sending four astronauts around the Moon.

NASA completed the agency’s Artemis II Flight Readiness Review on Thursday, March 12, and polled “go” to proceed toward launch. NASA is targeting Thursday, March 19, to roll the SLS (Space Launch System) rocket and Orion spacecraft to launch pad 39B in advance of a launch attempt Wednesday, April 1, pending close out of remaining open work.

The repair work involved replacing a helium seal that was preventing flow to and from the tanks and testing it to confirm the new seal worked. It also involved replacing batteries as well as some oxygen seals.

NASA officials also stated that they do not plan to do another wet dress rehearsal, that they are satisfied by the testing they did in the assembly building. Instead, they are go for full launch countdown, with the hope they can lift-off with no more fueling issues. They have also determined that if there is a scrub, they will also have several launch opportunities through April 6th.

To underline the risks of this mission, the Orion capsule in which they are sending four astronauts around the Moon has an uncertain heat shield and an untested life support system. To mitigate the shield uncertainties, they must hit a specific flight path through the atmosphere upon return.

Real change at the FCC?

1:51 pm

Brendan Carr during Breitbart interview
Brendan Carr during Breitbart interview

FCC chairman Brendan Carr this week didn’t simply make a public statement yesterday against Amazon, as I reported earlier today. The day earlier, on March 10th, he did an hour-long interview with Breibart News, providing a more complete summary of the FCC’s overall agenda since the change of administrations from Joe Biden to Donald Trump.

You can watch that interview here. To put it mildly, the shift in policy and approach at the FCC is significant, and appears to be generally moving in the right direction.

To understand the context, we need to first review the FCC’s approach during the Biden administration. My regular readers will remember the many stories during that time describing the FCC’s aggressive effort to expand its regulatory power, in many cases in areas completely exceeding its fundamental statutory authority. For example, it proposed new regulations designed to tell satellite companies how and when to de-orbit their satellites. It also wanted to its own bureaucracy for imposing those regulations, and went ahead and created it without any congressional approval. It also under Biden attempted to limit satellite operations that the astronomy community opposed, an action that was once again outside its statute authority.

Overall, the goal of the FCC under Biden was to expand the power of the administrative state, in as many areas as possible. And though there was push back from Congress, as long as a Democrat was president it was clear that this power-grab was going to grow exponentially.

After the 2024 election, however a Democrat was no longer president. Trump quickly moved in 2025 to squash the FCC’s power grab, with a stated public goal to instead streamline FCC regulations and speed license approvals.

Carr’s interview earlier this week essentially gave us an update on that Trump policy, and it appears this new anti-regulatory policy is moving forward, with a goal to eliminate ten regulations for every one regulation added. According to Carr:

A close-up of the dark side of Saturn’s moon Iapetus

11:55 am

Iapetus' equator ridge

Cassini's first global close-up of Iapetus
Click for original image.

Today’s cool image is a double-header! The picture above, cropped to post here, was taken on September 10, 2007 during Cassini’s fly-by of Saturn’s moon Iapetus, taken from approximately 1,000 miles above the surface. It looks at the dark side of this two-toned planet (see yesterday’s cool image). As the moon’s rotation is tidally locked so that one side always faces Saturn, one hemisphere always leads while the other always trails. For some reason still unexplained, the leading hemisphere is covered with an almost pitch-black material, while the trailing hemisphere is bright and very white, its icy surface quite visible.

For context, to the right is a global image of that dark side taken during Cassini’s first fly-by of Iapetus on December 31, 2004. This picture highlights the long ridge that runs along the planet’s dark hemisphere’s equator that was the focus of the close-up image above. From the 2005 press release:

The most unique, and perhaps most remarkable feature discovered on Iapetus in Cassini images is a topographic ridge that coincides almost exactly with the geographic equator. The ridge is conspicuous in the picture as an approximately 12 miles band that extends from the western (left) side of the disc almost to the day/night boundary on the right. On the left horizon, the peak of the ridge reaches at least 8 miles above the surrounding terrain. Along the roughly 800-mile-length over which it can be traced in this picture, it remains almost exactly parallel to the equator within a couple of degrees. The physical origin of the ridge has yet to be explained. It is not yet clear whether the ridge is a mountain belt that has folded upward, or an extensional crack in the surface through which material from inside Iapetus erupted onto the surface and accumulated locally, forming the ridge.

Iapetus itself has a diameter of about 900 miles, so this ridge essentially crosses most of the dark hemisphere.

The 2007 press release did not provide enough information to pinpoint exactly where along that ridge the close-up is located, but no matter. Both images make very clear what we are looking at.

China’s giant Spacesail constellation seeks more funding

9:57 am

Spacesail, one of the largest of China’s planned constellations designed to compete with Starlink, is now seeking more funding to build its full constellation of 10,000 to 14,000 satellites.

Shanghai Spacecom Satellite Technology, or SpaceSail, a satellite communications company developing a massive constellation known as “Qianfan,” disclosed plans to bring in new investors through a capital increase, according to a notice published on the Shanghai United Assets and Equity Exchange.

At present, this Chinese pseudo-company has launched only 119 out of the constellation’s first phase of 648 satellites. While it has gotten Airbus to sign a contract to use its constellation on its airplanes, it also appears to be somewhat cash poor, having only about $150 million on hand (much of it government funding), and is not going to meet its international licensing requirement to get those 648 satellites in orbit by the end of this year.

This new funding round announcement suggests it is in need of capital, and is having trouble getting the Chinese government to cough up the additional funds.
