Many Martian mysteries in one spot

Many Martian mysteries in one spot
Click for original image.

Just because there are no new images coming back from Mars at this time because the Sun is in the way does not mean we can’t enjoy more cool Martian images. The picture to the right, cropped, reduced, and sharpened to post here, was taken on October 20, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

Labeled merely a “terrain sample,” this means it was taken not as part of any particular research project but to fill a gap in the camera’s schedule. The camera team needs to take regular photographs in order to maintain the camera’s proper temperature, and when there is a long gap they add a terrain sample image to the schedule. Usually they try to pick some target of interest.

In this case the target is this 2,500-foot-high cliff, in which we can see a whole range of Martian geological mysteries. First there are the slope streaks on the cliff, a feature unique to Mars but as yet unexplained. Resembling avalanches, these streaks leave no debris piles at their base, do not change the topography in any way, and can appear randomly throughout the year, fading with time. Though the streaks in this picture are dark, streaks can also be bright.

Both the parallel ridges at the base of the cliff, as well as the cliff itself, are remnants of other major geological events, at least based on present theories.

SpaceX doing trial runs of specialized barge for transporting Starship/Superheavy from Boca Chica to Florida

9:32 am

SpaceX has now confirmed that it is doing trial runs of a barge specifically designed for transporting Starship/Superheavy from the manufacturing facility in Boca Chica to its Florida launchpads.

[SpaceX’s Vice President of Launch, Kiko] Dontchev also clarified that both the Super Heavy booster and Starship upper stage would be tilted to a horizontal position for maritime transit, in response to an artist’s rendering of a Starship traveling vertically aboard a vessel. “Initial deliveries are a single booster or ship per trip, with the plan to move to multiple vehicles per transit sooner than later,” he wrote. “You’ll thank me later.”

These barge trials, combined with the fact that SpaceX has already shipped significant Starship/Superheavy components to Florida even as it builds rocket manufacturing facility there, strongly suggest the first Florida launches are not too far in the future, possibly even this year.

ESA funds Danish lunar orbiter

9:16 am

The European Space Agency (ESA) has agreed to fund the first Danish-built interplanetary probe, a smallsat lunar orbiter dubbed Mani that will launch in ’29 and map the Moon’s surface.

The Máni mission is a lunar mission that will use a satellite to map the Moon’s surface with high-resolution images and create detailed 3D maps. The goal is to make it safer for astronauts and lunar rovers to land and move around on the Moon. The satellite will orbit the Moon’s north and south poles, which are key areas for future human missions.

The mission will also map how light reflects from areas on the Moon that are used to study Earth’s ability to reflect sunlight onto the lunar surface – the so-called earthshine. This knowledge could improve our understanding of how Earth’s climate will evolve.

The University of Copenhagen leads the mission and is responsible for the mission’s Science Operations Center, which will plan which areas to map and analyze the vast number of images generated.[emphasis mine]

I love how this European press release about a lunar orbiter somehow makes its most important mission studying climate change on Earth. Utterly idiotic.

Mani will use the changing shadows to create detailed topographic maps. As it is unlikely it will be capable of providing better data than produced over the past sixteen years by Lunar Reconnaissance Orbiter (LRO), this mission is mostly an engineering demo by Denmark and the Danish startup, Space Inventor, that is building the satellite for a consortium of universities. If successful the satellite will possibly be able to replace LRO (which is going to fail sooner or later), and provide data on any lunar surface changes that occur in the future.

SpaceX to do a major orbital reconfiguration of its Starlink constellation

9:03 am

According to a X post yesterday by Michael Nicholls, SpaceX’s Starlink engineering vice-president, the company over the next year will be lowering the orbits of more than 4,000 satellites in its Starlink constellation, in order to allow the company to more quickly de-orbit them if they fail.

We are lowering all Starlink satellites orbiting at ~550 km to ~480 km (~4400 satellites) over the course of 2026. The shell lowering is being tightly coordinated with other operators, regulators, and USSPACECOM.

Lowering the satellites results in condensing Starlink orbits, and will increase space safety in several ways. As solar mininum approaches, atmospheric density decreases which means the ballistic decay time at any given altitude increases – lowering will mean a >80% reduction in ballistic decay time in solar minimum, or 4+ years reduced to a few months. Correspondingly, the number of debris objects and planned satellite constellations is significantly lower below 500 km, reducing the aggregate likelihood of collision.

Nicholls notes that it presently has only two dead satellites in the present fleet of 9,000 satellites, but decided to do this move regardless, as it also apparently will reduce collision risks with other satellites as well.

Not surprisingly, China’s state-run press and our anti-capitalism propaganda press immediately tried to give China credit for this change, while lambasting SpaceX. That China is contributing to the risk of collision with its own multiple giant satellite constellations and is doing nothing on its own is apparently irrelevant to both. Our nice of them.

The three week communications blackout from Mars has begun

11:30 am

Last image before blackout from Curiosity

Last image before blackout from Perseverance
Click for original.

The two images to the right, both downloaded today (here and here) from the Mars rovers Curiosity (top) and Perseverance, illustrate quite clearly the beginning of the three-week-long communications blackout from Mars caused every two years when the orbits of Earth and Mars places the Sun in-between. As the Curiosity science team noted in a December 22, 2025 update:

This holiday season coincides with conjunction — every two years, because of their different orbits, Earth and Mars are obstructed from one another by the Sun; this one will last from Dec. 27 to Jan. 20. We do not like to send commands through the Sun in case they get scrambled, so we have been finishing up a few last scientific observations before preparing Curiosity for its quiet conjunction break.

Apparently engineers were able to squeeze data and images from Mars for a few extra days, but the incomplete nature of these two pictures — combined with the lack of any other new images today — tells us that the blackout has definitely begun. That they were able to get these additional images after conjunction began suggests the blackout might also end a bit earlier than expected.

Though there is always a concern that something could go wrong while communications are blocked, the risks are small. The science teams for all the Mars orbiters and rovers have dealt with this situation now almost a dozen times since operations became routine there more than a quarter century ago.

The only spacecraft at real risk this conjunction is Maven. Contact was lost from it in early December for unknown reasons, and all efforts to regain communications have so far failed. All engineers know from the little data they have gotten back is it appears to be tumbling. This three week blackout will make any chance of recovery extremely unlikely.

The global launch industry in 2025: The real space race is between SpaceX and China

8:01 am

In 2025 the worldwide revolution in rocketry that began about a decade ago continued. Across the globe new private commercial rocket companies are forming, not just in the United States. And across the globe, the three-quarters-of-a century domination by government space agencies is receding, though those agencies are right now pushing back with all their might to protect their turf.

Dominating this revolution in 2025 in every way possible however were two entities, one a private American company and the second a communist nation attempting to imitate capitalism. The former is SpaceX, accomplishing more in this single year than whole nations and even the whole globe had managed in any year since the launch of Sputnik. The latter is China, which in 2025 became a true space power, its achievements matching and even exceeding anything done by either the U.S. or the Soviet Union for most of the space age.

Turkey and Somalia confirm spaceport plans

9:14 am

Somalia

In a public meeting of the presidents of Turkey and Somalia in Istanbul yesterday, Turkish President Recep Erdogan confirmed that Turkey has begun construction of a spaceport in Somalia.

Astrophysicist Umut Yildiz said the project, announced by President Recep Tayyip Erdogan and detailed by Industry and Technology Minister Mehmet Fatih Kacir, offers Türkiye significant geographic and technological opportunities.

…President Erdogan said the first phase of the three-stage project has been completed and construction has begun under the Türkiye Space Agency, adding that the goal is to establish significant infrastructure in space launch and satellite technologies.

Minister Kacir said the spaceport will become a strategic, revenue-generating infrastructure for Türkiye through growing commercial satellite launch services, testing activities and integration processes, while also contributing to Somalia’s development.

This spaceport plan had first been revealed by Turkish officials two weeks ago, but yesterday’s press conference now makes it official.

No press release from Turkey’s state-run press however revealed the spaceport’s precise location in Somalia. Nor is it confirmed that any actual construction has begun. I suspect it will be a very long time before anything actually launches from the site.

Space Force requests proposals for new Vandenberg launchpad for heavy and super-heavy rockets

8:07 am

Vandenberg Space Force Base

The Space Force on December 29, 2025 released a request for information (RFI) from the private sector for building a new launchpad at the southern-most tip of Vandenberg Space Force Base, for use by “new” heavy and super-heavy rockets.

The Space Force said it prefers to use the site for new vehicles rather than ones that already have launch sites at Vandenberg, to “increase launch diversity” at the base. The service is also interested in vehicles with “unique capabilities,” such as point-to-point transportation or the ability to return payloads.

The RFI emphasizes the need for “technically mature” vehicles capable of operating from SLC-14 within five years of signing a lease agreement. Companies must also provide details about their operations to address safety concerns and minimize impacts on other launch operators at the base.

You can read the actual RFI here. The map to the right, taken from the RFI and annotated to post here, labels the area under consideration as “Sudden Flats”. SpaceX’s two launchpads are indicated, with SLC-6 presently under development.

Though the description of the request appears to favor SpaceX, it could also apply to Blue Origin’s New Glenn as well as the company’s proposed larger versions of that rocket.

The request asks for proposals within 30 days.

China launches two satellites for “new technology verification for space target detection”

7:55 pm

China today successfully launched two technology test satellites designed to do “space target detection”, its Long March 7A rocket lifting off from its coastal Wenchang spaceport.

China’s state-run press provided no other information. It also appears the drop zones for the rocket’s lower stages were once again in Philippino waters, requiring that government to warn its citizens to avoid those zones and subsequent any rocket debris.

The leaders in the 2025 launch race:

168 SpaceX
90 China (a new record)
18 Rocket Lab
17 Russia

SpaceX still leads the rest of the world in successful launches, 168 to 150.

At this moment no other launches are scheduled before the end of the year, thus closing out the 2025 year in rocketry. I will publish my annual global report in the next few days. Stay tuned.

The up and down tale of two rocket startups, Vector and Phantom

11:01 am

Jim Cantrell and cars
Jim Cantrell at Vector in 2017, shown in front of
one of his side businesses, fixing and refurbishing race
cars and rare luxury sports cars (located then at Vector).

The tales of rocket startups are often fraught with ups and downs of all kinds, often traveling in circles that no one can ever predict. This is one such tale.

In the mid-2010s there was a rocket startup called Vector, based here in Tucson, founded by a guy named Jim Cantrell. At that time Cantrell pushed the company in the style of Elon Musk, going very public for publicity and to raise investment capital.

He was remarkable successful at both. Unfortunately, his engineers were not as successful at engine building. After years of effort they all realized that their rocket engines were under-powered, and wouldn’t be able to get the rocket into orbit. In 2019 the company’s biggest investor backed out, Cantrell left the company, and new owners took over, hoping to rebuild.

Flash forward to 2021, and Jim Cantrell has reappeared with a new rocket company, Phantom Space, also based in Tucson, raising $6 million in seed capital. In the next four years he obtained a small development contract from NASA, completed two more investment rounds raising first $22 million and then around $37 million, and began development of a new orbital rocket, dubbed Daytona. The company also began work on its own small satellite constellation, PhantomCloud (more on this later).

As for Vector, there was little to report during those four years. The only update said the company was buying engines from the rocket engine startup Ursa Major, the same company Phantom was using.

It is now the end of 2025, and the fate of these two companies has once again intertwined, in a most ironic manner. Last week I learned from Jim Cantrell that Vector had closed shop, and that its last remaining assets, some of which Cantrell himself had helped develop when he headed Vector, had been bought by Phantom. This includes several unused rocket stages, the vertical rocket test stands, a lot of computers, and hardware.

Colliding galaxies, as seen in the infrared and X-rays

9:02 am

Colliding galaxies in the infrared and X-rays
Click for original image.

Today’s cool image illustrates how beautiful images of heavenly objects don’t always have to be in wavelengths our eyes can see. With the wonders of modern technology, we can now see wondrous things in wavelengths that are invisible to us.

The picture to the right, cropped and reduced to post here, is a perfect illustration. It was released on December 1, 2025, and combines X-ray data from the Chandra X-ray Observatory with infrared data from the Webb Space Telescope. From the caption:

This view of NGC 2207 and IC 2163 takes a James Webb mid-infrared image (white, gray, and red) and adds the X-ray view from Chandra (blue). Together, it is quite an eye-catching result.

…Here, both spirals are shown face on, with the smaller of the two galaxies, IC 2163, at the upper left of the larger galaxy, NGC 2207, which dominates the center and lower right of the image. Both galaxies have long, spiraling, silver blue arms, dotted with specs of blue and red. Toward our upper left, the curving arms overlap, and bend toward their neighbors’ core.

In optical wavelengths the gossamer lines of structure would be lost, overwhelmed by the light of each galaxy’s stars.

European Space Agency hacked

8:43 am

It appears some of the European Space Agency’s (ESA) servers have been hacked, with some of its internal data placed for sale on the web.

On 26 December, reports began to emerge on X claiming that ESA had suffered a significant data breach, with a hacker using the alias “888” offering more than 200 gigabytes of data for sale. According to the hacker’s listing, the allegedly compromised data included source code for proprietary software, sensitive project documentation, API tokens, and hardcoded credentials.

ESA has since issued a statement claiming the data breach was limited, but according to information posted on X, the breach included “Confidential internal documents (Airbus Defence & Space, Thales Alenia Space)” and “sensitive technical information related to space programs.”

I wouldn’t be surprised if China is bidding for this information right now. Then again, Europe’s space effort is so unimpressive compared to China that China might not see the information worth much.
