Orbital tug startup Starfish Space wins $52.5 million Space Force contract to de-orbit its defunct satellites

The orbital tug startup Starfish Space yesterday announced it has been awarded a $52.5 million contract from the Space Force’s Space Development Agency (SDA) to use its Otter tug to de-orbit satellites when they have reached their end-of-life.

Under the contract, Starfish Space will build, launch, and operate an Otter spacecraft in low Earth orbit (LEO) to safely and efficiently dispose of SDA satellites at the end of their operational lives. The mission begins with an initial deorbit, with options for multiple additional deorbits, enabled by Otter’s significant capacity and ability to service several satellites in a single mission. The mission is targeting launch in 2027.

While a number of contracts have been issued in the U.S., Europe, and Japan to demonstrate de-orbit technology, this is the first operational contract ever issued. Moreover, I don’t think any of those other demo missions have actually achieved a de-orbit as of yet. Starfish itself has only successfully demonstrated rendezvous and proximity capabilities on two missions, with a third a failure. In the most recent late last year (as shown by the image on the right), Impulse’s Mira tug used Starfish software and camera to move within 1.2 kilometers of another Mira tug.

As for docking, its Otter Pup tug has flown two missions. The first failed in 2023 when both spacecraft began spinning unexpected. The second was supposed to achieve a docking, but after completing rendezvous maneuvers the company has provided no new updates. As far as we know, the docking never occurred or was a failure.

Nonetheless, it appears Starfish’s overall recent performance convinced the Space Force it could handle this new de-orbit contract.

Communications resume with Mars

1:02 pm

First images back from Curiosity and Perseverance
Go here and here for the original images.

It appears the solar conjunction that has blocked all communications with the rovers and orbiters for the past three weeks around Mars has now fully ended, with the first new images appearing today from both Curiosity and Perseverance.

The two images to the right were downloaded today. The top image was taken on January 20, 2026 by Curiosity’s front hazard avoidance camera. It appears to be looking uphill in the direction the rover is soon to travel, climbing Mount Sharp. If you look closely you can see the mountain’s higher ranges on the horizon, just to the right of the rover itself.

The bottom picture was actually taken on January 15, 2026 by Perseverance, but was only downloaded today. Both science teams had programmed their rovers to take images throughout the conjunction, scheduled for download when communications resumed.

The picture was taken by Perseverance’s left high resolution camera located on top of the rover’s mast. It looks down at the ground near the rover at the pebbles and rocks that strewn the relatively smooth surface of the terrain west of Jezero crater.

Neither image is particularly ground-breaking. What is important however is that both images prove the rovers are functioning as expected. Expect a lot more data to arrive in the next few days, all gathered during three weeks of blackout.

Haven-1 launch delayed until 2027

12:35 pm

According to Vast’s CEO, Max Haot, the launch of its single module Haven-1 space station has now been pushed back to the first quarter of ’27.

Last Saturday (January 10) we reached the key milestone of fully completing the primary structure, and some of the secondary structure; all of the acceptance testing occurred in November as well. Now we are starting clean room integration, which starts with TCS (thermal control system), propulsion, interior shells, and then moving on to avionics. And then final close out, which we expect will be done by the fall, and then we have on the books with NASA a full test campaign at the end of the year at Plum Brook. Then the launch in Q1 next year.

Until recently the company had been targeting a launch in the first half of 2026. This is a delay of almost a full year, and suggests the previous launch date has not been a serious target for quite some time.

Haot at the article at the link provides some new details about the manned missions to the station. It will launch unmanned, and after check-out in orbit that could last two weeks or longer, a professional SpaceX Dragon crew will fly a two-week mission there to do further check-outs.

After this up to three more two-week missions are planned, with Vast already having a deposit for the first. It also is willing to do more during Haven-1’s three year lifespan.

More and more it appears to me that in my rankings below of the five commercial space stations presently under development, the top three space stations are practically tied. And of the five stations, three are hoping to begin launching modules in the ’27-’28 time frame.

French startup The Exploration Company negotiating purchase of UK rocket startup Orbex

8:39 am

In what appears to be a direct consequence of British red tape blocking Orbex from launching in the past four years, it is now in negotiations to sell its assets to the French startup The Exploration Company.

On 21 January, Orbex published a brief press release stating that a letter of intent had been signed and that negotiations had begun. The company added that all details about the transaction remain confidential at this stage. A statement from Orbex CEO Phil Chambers suggests that the company’s financial position factored into its decision to pursue a buyer. “Our Series D fundraising could have led us in many directions,” said Chambers. “We believe this opportunity plays to the strengths of both businesses, and we look forward to sharing more when the time is right.”

Let me translate: In 2022 Orbex had set up a factory close to the proposed Sutherland spaceport on the north coast of Scotland, had signed a 50 year lease with that facility to launch its Prime rocket there, had built a launch platform and tested a prototype of the rocket, and was poised to do its first launch. All it needed was license approvals from the United Kingdom’s Civil Aviation Authority (CAA).

And then it waited, and waited, and waited, and waited. By 2024 it gave up on Sutherland, because the authorities (local and national) kept rejecting its spaceport license for environmental and political reasons. It switched its launch site to the SaxaVord spaceport on the Shetland Islands, pushing back that first launch to 2026. Along the way the UK gave it a $25 million grant, likely to keep the company above water because the UK was blocking its ability to launch.

All for naught. It is very clear Orbex has run out of cash waiting, and is now looking to salvage its work by selling everything to the French company, which so far has focused on building a cargo capsule to supply the upcoming commercial space stations.

If the sale goes through, do not be surprised if Orbex’s assets exit the UK entirely. And at that point, the CAA’s red tape can be given credit for destroying a second rocket company, following Virgin Orbit.

JAXA releases preliminary results of investigation into December 2025 H3 rocket launch failure

8:01 am

Japan's space agency JAXA

JAXA yesterday released the preliminary results of its investigation into upper stage failure during the December 2025 launch of its H3 rocket.

Previously the agency had indicated it believed the cause was linked to the separation of the rocket’s payload fairings. This new report changes that conclusion:

After liftoff, the No. 8 H3 rocket sustained damage to the section where the Michibiki No. 5 positioning satellite was mounted, when the satellite cover, called fairing, was separated.

In addition, the fuel tubing of the rocket’s second-stage engine was damaged, presumably causing combustion to stop earlier than planned, JAXA said in a progress report on its investigation into the failure at a meeting of a subgroup of a science ministry panel.

As the section was damaged, the satellite was no longer attached to the second stage of the rocket. The satellite fell off when the first stage separated.

In other words, as the fairings released, the satellite apparently deployed, damaging the fuel feed to the upper stage engine. It is as yet unclear whether the deployment system worked as intended, but did so prematurely, or if it failed entirely, allowing the satellite to fall away once the fairings separated.

At the moment Japan has no launch capability. Both of JAXA’s rockets, the H3 and the Epsilon-S are grounded due to launch failures. Meanwhile, the country has only recently begun to develop private launch companies, none of which are ready to launch.

Computer simulations suggest Jupiter and Saturn have fundamentally different interiors

9:57 am

The different polar vortexes of Jupiter and Saturn

The uncertainty of science: In attempting to explain why the polar vortexes of Jupiter and Saturn are so different, scientists running large computer simulations have found that the difference could be because Jupiter’s interior is “softer” than Saturn’s.

The two images to the right illustrate the different polar vortexes of both planets. Jupiter’s (top) is made up of multiple chaotic small storms that form a hexagon-like ring around the pole. Saturn’s (bottom) is a single very coherent hexagon-shaped storm.

Over multiple different simulations, they observed that some scenarios evolved to form a single large polar vortex, like Saturn, whereas others formed multiple smaller vortices, like Jupiter. After analyzing the combinations of parameters and variables in each scenario and how they related to the final outcome, they landed on a single mechanism to explain whether a single or multiple vortices evolve: As random fluid motions start to coalesce into individual vortices, the size to which a vortex can grow is limited by how soft the bottom of the vortex is. The softer, or lighter the gas is that is rotating at the bottom of a vortex, the smaller the vortex is in the end, allowing for multiple smaller-scale vortices to coexist at a planet’s pole, similar to those on Jupiter.

Conversely, the harder or denser a vortex bottom is, the larger the system can grow, to a size where eventually it can follow the planet’s curvature as a single, planetary-scale vortex, like the one on Saturn.

If this mechanism is indeed what is at play on both gas giants, it would suggest that Jupiter could be made of softer, lighter material, while Saturn may harbor heavier stuff in its interior.

This conclusion however runs completely counter to what we should expect. Jupiter has a much great mass, and one would assume from this that its interior would therefore be denser and thus harder.

The Australian rocket startup Gilmour Space, whose one orbital test launch in 2025 failed, has now raised an additional A$217 million ($145 million American) in investment capital, in addition to the A$142 million it had previously raised.

The Series E round was jointly led by the National Reconstruction Fund Corporation (NRFC) and Hostplus, with participation from Future Fund, Blackbird, Funds SA, HESTA, NGS Super, Main Sequence, QIC, and Brighter Super.

…Proceeds from the raise will be used to support continued development and qualification of its Eris orbital launch vehicle, scale rocket and satellite manufacturing, expand test and launch infrastructure, and grow the company’s workforce to meet global demand for space launch services.

The National Reconstruction Fund Corporation is a government agency with a A$15 billion budget tasked to help finance new industries. It contributed A$75 million in this fund raising round.

The other major contributor was Hostplus, which matched that contribution.

Though the company has said it will attempt a second orbital test launch in 2026, no dates have been announced.

Update on NASA’s damaged Goldstone antenna

8:25 am

According to a scientists at JPL, the Goldstone antenna — one third of NASA’s Deep Space Network (DSN) that scientists and NASA use to communicate with any interplanetary mission — will not resume operations until May of 2026.

The antenna has been out of service since September 2025 when it was damaged badly by workers who rotated the antenna past its correct limits, causing damage to piping and cables.

DSS-14 is officially scheduled to resume operations May 1, Benner said. “Unofficially, this might change. We’re hearing a variety of things,” he added, without specifying whether the return could be earlier or later. He noted that DSS-14 had already been scheduled to go offline in August 2026 for extended maintenance expected to last until October 2028, replacing equipment that in some cases is 40 to 50 years old.

In other words, this outage essentially took the antenna out of service a year early.

The outage can be covered by NASA’s other two DSN antennas in Spain and Australia, but it also limits the whole network’s capabilities. When Artemis-2 launches in the next month or so this limitation will significantly reduce communications with NASA’s other planetary missions at Mars and elsewhere during that mission’s 10-day flight around the Moon.

We still do not know the cause of the over-rotation, which at present does appear to have been the result of human carelessness. And NASA’s lack of transparency in this matter reinforces that speculation.

New spaceport proposed in India independent of its space agency ISRO

The existing and proposed spaceports in India
The existing and proposed spaceports in India

According to the chief minister of the Andhra Pradesh province of India, his government is presently in discussions with the private Indian energy company Greenko Group about establishing a partnership to build a commercial spaceport at Hope Island off the coast near the city of Kakinada.

Addressing the gathering of foreign investors in renewable energies and officials of the State government after performing ‘bhumi puja’ [ground-breaking] for the Green Hydrogen and Green Ammonia Production Complex in Kakinada, Mr. Naidu said, “Soon, we (Andhra Pradesh) will launch satellites from the Hope Island. It will come soon, and Kakinada will have a lot of advantages in the field of technology and innovation.”

“The Greenko Group is evincing interest in being a part of the State government’s Space City project that includes developing satellite launching facility. In a recent interaction, Greenko Founder and Group CEO Anil Kumar Chalamalsetty has shown interest in the Space City project on the Hope Island,” said Mr. Naidu.

The location has advantages over the Sriharikota spaceport, run by India’s space agency ISRO, which on polar orbital launches needs to use extra fuel to avoid flying over Sri Lanka to the south. This issue is one of the reasons ISRO is presently building that second spaceport to the south for its SSLV rocket.

If privately run, this new spaceport will have other advantages. It will possibly attract some of India’s new rocket startups, who will avoid some of the bureaucracy that accompanies any dealings with ISRO. ISRO launches always involve a gigantic number of government personnel, a cost these startups can’t afford. This new Hope Island spaceport might avoid these costs with low overhead and efficient operations.

Nothing is firm yet. From the statement above, it appears the negotiation is in a very preliminary stage, and might never bear fruit.

Hat tip BtB’s stringer Jay.

Another Zimmerman op-ed today at PJ Media

9:17 pm

Our mindless propaganda press
Our mindless propaganda press

PJ Media tonight posted another op-ed by yours truly:

Artemis II Ready for Dress Rehearsal: Propaganda Press Misses the Real Story of This Dangerous Mission

My readers know I strongly oppose flying this mission manned because of questions about Orion’s heat shield and its untested life support system. In this op-ed however my purpose was not to argue this point again. Instead, I wanted to take our bankrupt media to task for their utter failure to report these facts.

When NASA this past week rolled SLS/Orion to the launchpad, I was appalled by the coverage. In reviewing every article I could find about that rollout, it seemed I was “reading the state-run presses of China and the Soviet Union”, not a free independent press charged with covering the news.

The write-up of every one of these so-called news outlets is cloying and worshipful. The worst examples are those that focus on the ridiculous quote by one astronaut, “We are very likely going to see things that no human eye has ever seen.” This may be true (four humans will see the Moon from a new perspective), but it is hyperbole of the worst sort. Not only have humans circled the Moon before, but unmanned orbiters have also mapped the entire globe at a resolution far better than anything that will be visible to the Artemis-II crew.

Furthermore, these media reports repeat without any questioning NASA’s very false claim that it has done everything possible to make sure this flight is safe.

Only one article out of almost 20 news outlets mentioned Orion’s questionable heat shield, and that article made it seem as if NASA had fixed the problem. None of the articles even mentioned the fact that Orion’s life support system will be flying in space for the very first time, essentially using four human beings as guinea pigs.

Instead, every article was a propaganda piece extolling mindlessly the wonders of NASA and this mission, making believe all was perfect and well planned.

This is bad journalism of the worst sort. If you are going to report on this mission, good journalism requires you to at least note these issues. In fact, good journalism demands it, because it actually makes for a much better story: NASA is sending four astronauts around the Moon in a capsule with questionable engineering!

A 10-mile-long avalanche on Mars

11:32 am

Overview map

A ten mile long avalanche on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on November 8, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows only three miles of a ten-mile-long avalanche inside the solar system’s largest canyon, Valles Marineris.

The white dot on the overview map above marks the location. In the inset the white rectangle indicates the area covered by the picture to the right. I have indicated the avalanche’s full extent beyond this.

Overall, the landslide fell about one mile along those ten miles. That there are about a dozen small craters on top of the slide tells us this happened quite a long time ago.

As always, the scale of Valles Marineris boggles the mind. Though this avalanche fell about 5,000 feet (the same depth of the south rim of the Grand Canyon), that drop only covered one fifth of Valles Marineris’s depth. At this point, from the rim to the floor the elevation difference is about 23,000 feet, which would place the rim among the 100 highest mountains on Earth. And of course, this is only one small spot in this gigantic canyon that runs 2,500 miles east-to-west, with its depth about the same that entire length.
