Update on Superheavy/Starship: Both ships doing final static fire testing

2:41 pm

Link here. The report includes a lot of very interesting information about how SpaceX is evolving its launch platforms and the tank farms that fuel the stages in order to make them operate more efficiently. For example:

In the past, on Pad 1, SpaceX had only four Liquid Oxygen (LOX) Pumps and six subcoolers, and three Liquid Methane (LCH4) Pumps with three subcoolers. This setup allowed SpaceX to start booster load at T-41:15 on Flight 11.

On Pad 2, SpaceX has five pumps and about 10 subcoolers worth of capacity on the LOX side, and four pumps alongside about six subcoolers worth of capacity on the LCH4 side. With these upgrades, along with larger supply lines, SpaceX can now load a full booster within 30 minutes, and each LOX ring takes only about 90 seconds to load. This now means SpaceX can load the Superheavy booster faster than a Falcon 9 and carry over 10 times the propellant. [emphasis mine]

Many of the tests have been more to prove out the fueling systems and launchpad than to test Superheavy.

Other tests however have been to prove out the new Raptor-3 engine. The company have increased the number of engines step by step so that the next test will be the first to test all 33 engines. I suspect that test will also be the full dress rehearsal countdown prior to launch.

Starship meanwhile is undergoing testing on the company’s nearby Massey test stand, the one that I think was rebuilt after an explosion last year.

Stay tuned. It appears the next and 12th orbital test flight will not be long in coming.

All is well

11:40 pm

All is well but there are some minor complications that will take up my time for the next few days. I might get time to post soon, but the priority is dealing with my health.

My deepest thanks to everyone for their well wishes. I really appreciate it.

A pause in posting…

6:30 am

Readers!

Do not expect many posts by me today or for the next few days. I am undergoing knee replacement surgery today, and will not be in shape for any work for at least the next day or so. Depending on my recovery, I could be posting by tomorrow, but don’t bet on it. More likely I will begin to resume work later in the week.

Today’s quick links will go up mid-morning. I have also scheduled evening pauses, so enjoy these. Other than that you will have to wait for my return for much else. I will then make sure to catch up and put up posts covering all the space news that occurred during this pause.

Note that such surgery these days is almost routine, so all should be well. I am hoping it will allow me to once again hike as I have done for my whole life, before the bones in the left knee in November decided to kiss painfully with each bend.

Three launches, two by SpaceX and one by China

10:10 am

Falcon 9 landing for its seventh time
Falcon 9 landing for its seventh time on today’s
third launch. See below.

Since last night there were three launches globally, two by SpaceX, and one by China.

First, in the wee hours of the morning SpaceX placed 25 more Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California. The first stage (B1063) completed its 32nd flight, landing on a drone ship in the Pacific. With this flight, 43 days after the stage’s previous flight, it moved into a tie for fourth place in the rankings of the most reused launch vehicle:

39 Discovery space shuttle
34 Falcon 9 booster B1067
33 Atlantis space shuttle
32 Falcon 9 booster B1071
32 Falcon 9 booster B1063
30 Falcon 9 booster B1069
28 Columbia space shuttle
27 Falcon 9 booster B1077
27 Falcon 9 booster B1078

Sources here and here.

Next China launched a classified satellite to test “internet technology”, its Smart Dragon-3 (Jielong-3) rocket lifting off from a sea platform in international waters in the South China Sea. Though China has launched numerous times from this sea platform, previous launches were very close to the shore. This was the first time the platform was moved this far into the ocean.

Finally, SpaceX completed its second launch in less than eight hours, sending Northrop Grumman’s Cygnus capsule on its way to ISS with 11,000 pounds of cargo, its Falcon 9 rocket lifting off from Cape Canaveral Space Force Station in Florida. The first stage completed its seventh flight, landing back at Cape Canaveral. Of the two fairings, one was making its first flight, while the other was on its fifth flight.

This was SpaceX’s fourth Cygnus launch for Northrop Grumman. The company originally launched Cygnus on its own Antares rocket, but when that rocket ran out of its Russian first stage engines it was grounded. The company hired Firefly to build a new first stage, but that project remains uncompleted.

Cygnus is scheduled to berth with ISS in two days, on Monday, April 13, at 12:50 pm (Eastern).

The leaders in the 2026 launch race:

44 SpaceX
19 China
5 Rocket Lab
4 Russia

For the third straight year SpaceX continues to lead the entire world combined in total launches, 44 to 33.

A military pilot’s perspective on downed pilot rescue in Iran Easter weekend

6:01 pm

An evening pause: The details of the amazing search & rescue effort to recover a downed American pilot in Iran last weekend has been covered quite thoroughly in the media, especially the alternative press. This video gives us the compelling perspective of the men and women who made that rescue happen. Even if you oppose Trump’s present actions against Iran, Steeve’s reveals a fundamental aspect of the American way of war that illustrates again the best part of America. The key quote, “Will you be worth the trip?”

Orion survives re-entry, crew splashes down safe

5:27 pm

Orion just after main parachute deployment
Orion just after main parachute deployment

Orion successfully survived re-entry tonight with its questionable heat shield, with the capsule splashing down off the coast of California at 8:07 pm (Eastern).

All four astronauts are healthy and safe. As of posting they were still in the capsule, floating on the ocean, with recovery crews on their way to it. [Update: those recovery crews, six boats with more than 40 people, are taking an ungodly amount of time to latch onto the capsule and begin recovery. Over an hour after splashdown the crew is still in the capsule.]

The Artemis-2 mission is now over, though the final condition of that heat shield still needs to be analyzed. In addition, engineers need figure out how to fix a bunch of other issues that took place during the mission:

  • A leak in an internal helium tank on Europe’s service module
  • Communication drop-outs several times
  • the endless issues with Orion’s toilet

There were other minor issues that cropped up repeatedly, none significant but all of which should be fixed. And though it will be helpful to determine how this heat shield performed, it should be noted that the data is essentially irrelevant to future missions. The next mission, Artemis-3, will use a completely different design, and test it for the first time on a manned flight. That flight however will be in Earth orbit, so the stress on the shield will be far less than this return, even with the changed re-entry path.

Though many will call this lunar fly-by “historic,” it will likely be little remembered by future generations. It did little to move the settlement of the solar system forward. No truly useful engineering was tested. The rocket and capsule are engineering dead-ends. Neither will be of much use for establishing colonies on the Moon or Mars, as SLS is still too expensive and too difficult to stack and launch and Orion is too small for any interplanetary missions, being nothing more than an overweight and very expensive ascent/descent capsule.

The only plus of this mission is that it will likely give NASA’s administrator, Jared Isaacman, the political clout to institute major changes in the entire Artemis program, changes that could make the American colonization of the solar system more likely. There are strong indications that he wants to make better use of the private sector.

And that private sector is poised to bypass NASA, regardless of what NASA wants or tries to do, with capabilities far better then anything we have seen since the Apollo program.

Orion’s risky return-to-Earth happens tonight at 8:07 pm (Eastern)

9:47 am

Click for original image.

After spending ten days in space, including a swing around the back of the Moon, the four-person Artemis-2 crew is now preparing for its return-to-Earth this evening, splashing down off the Pacific coast near San Diego.

At 10:53 p.m. EDT [last night], the Orion spacecraft ignited its thrusters for 9 seconds, producing an acceleration in velocity of 5.3 feet-per-second and pushing the Artemis II crew toward Earth. The crew is now more than halfway home.

About two hours before the burn, there was an unexpected return link loss of signal during a data rate change affecting the transmission of communications and telemetry from the spacecraft to the ground. Two-way communications were reestablished, and flight controllers resumed preparing for the upcoming burn with the crew shortly after.

…The third return trajectory correction burn is scheduled for April 10 at about 1:53 p.m. ahead of re-entry procedures.

This is I think the second time Orion has had a short loss of communications with ground control. In addition, the crew had to cancel a planned manual piloting demonstration of Orion while it flew past the Moon because of a leak in an internal helium tank, used to maintain pressure in the oxygen tank as the propellant is used. The leak was inside the European-built service module, which will be jettisoned before re-entry and burn up in the atmosphere.

Mission managers say this leak has not impacted any engine burns, but it will require attention before the next flight.

The return to Earth however carries the biggest risk of the entire mission. Orion’s heat shield is questionable. During its first use in the 2022 unmanned Artemis-1 flight around the Moon, it did not behave as expected, with large chunks breaking off instead of thin layers ablating away. Though mission engineers have adjusted the flight path through the atmosphere to mitigate stress, there is great uncertainty about that solution.

I have embedded NASA’s live stream of the return-to-Earth below. It begins at 6:30 pm (Eastern), though the first return event, jettison the service module, doesn’t occur until 7:33 pm (Eastern).

Amazon to begin commercial availability of Leo internet service in mid-2026

9:21 am

Amazon Leo logo

In an annual letter [pdf] to shareholders, Amazon’s CEO Andy Jassy announced the company plans on inaugurating its Leo internet constellation to customers in “mid-2026,” assuming the company can get a significant more satellites in orbit in the next few months.

Jassy’s wording was interestingly vague, however, suggesting this target date is very uncertain.

Over the last seven years, we’ve built a low Earth orbit satellite network (Amazon Leo) and put more than 200 satellites into space (which is the third-largest low Earth orbit network operating today). With a few thousand more satellites launching in the coming years, the constellation is expanding rapidly.

…While Amazon Leo is officially scheduled to launch in mid-2026, we already have meaningful revenue commitments from enterprises and governments.

To be precise, Amazon presently has launched 241 satellites, out of the 1,616 it needs to launch by July 2026 to meet its FCC license requirement. Because it is not expected to meet that requirement, the company has asked for a time extension, which the FCC is presently considering. The entire first generation constellation is supposed to have 3,232 satellites, so it seems unlikely Amazon will be able to provide internet service by mid-2026, as promised. It won’t have enough coverage with less than a fourth of its constellation in orbit.

India conducts another parachute drop test for its Gaganyaan manned capsule

9:03 am

Gaganyaan drop test
Click to watch video of drop test.

India’s space agency ISRO today successfully completed its second helicopter drop test of a dummy capsule, testing the parachute release system that its Gaganyaan manned capsule will use on return to Earth.

In this test, a simulated Crew Module, weighing about 5.7 tonnes, that is equivalent to the mass of the Crew Module in the first uncrewed Gaganyaan mission (G1), was lifted by an Indian Air Force Chinook helicopter to an altitude of about 3km and released over a designated drop zone in sea, near to Sriharikota coast.

Ten parachutes of four types were deployed in a precise sequence during the descent of the Crew Module, gradually reducing the velocity for safe touchdown. Subsequently, the simulated Crew Module was successfully recovered in coordination with Indian Navy. The IADT-02 test validated the parachute-based deceleration systems in the Crew Module.

The manned mission is presently scheduled for early next year, after a series of unmanned orbital test flights are completed in ’26. This schedule is significantly later than ISRO’s original schedule. When the program was first proposed in 2018, ISRO said the manned mission would happen in 2022.

China launches another set of satellites for its Guowang internet constellation

8:52 am

China yesterday successfully completed the 21st launch for its Guowang (Satnet) internet satellite constellation, its Long March 6A rocket lifting off from its Taiyuan spaceport in northeast China.

Though China’s state-run press provided no information on the number of satellites in the payload, all previous launches using the Long March 6A had carried five satellites. If so, that would mean the constellation now has 164 satellites in orbit, out of a planned 13,000. This fits with the information in the article at the link, which states the constellation now has “nearly 170 satellites” in orbit.

China’s state-controlled press also made no mention about where the rocket’s core stage (using very toxic hypergolic fuels) and its four solid-fueled strap-on boosters crashed inside China.

Another launch attempt today by the German rocket startup Isar Aerospace was scrubbed due to “a leak in a composite overwrapped pressure vessel (COPV).” COPV tanks are used inside the main tanks. As the propellant in that main tank is used, the COPV releases helium to maintain the tank’s pressure. No new launch date has been announced.

The leaders in the 2026 launch race:

42 SpaceX
18 China
5 Rocket Lab
4 Russia

For the third straight year SpaceX continues to lead the entire world combined in total launches, 42 to 32. It has another Starlink launch scheduled for this evening.

Now on Starlink!

9:37 pm

Starlink logo

My posting this afternoon today was interrupted because I was spending the day going up and down from my roof as I and friend Ken worked to install my new Starlink antenna.

As always with these kinds of jobs, there were moments that reminded me of a motto of mine when I used to assembly Ikea furniture as a part-time job: “It’s ‘Do everything twice day!'” In the end, the problems were minor and quickly solved, such as discovering that the Starlink ethernet cable from the power supply to the router could only be plugged in in one direction. The plugs on either end looked identical, but we struggled for almost twenty minutes trying to get the plug to click into the router, to no avail. Then a light bulb went off, and we decided to flip the cable. Lo and behold, both ends clicked in instantly.

Setting up the account and the Wi-Fi and the computers went very quickly, mostly thanks to my lovely wife Diane. Starlink only allows you to do this stuff on a smart phone, and I won’t touch one of those with a 200-foot pole. She got it all going within a very short time.

I had hesitated doing this for the past two years, mostly because it involved a lot of other non-Starlink-related time-consuming stuff too boring to describe but that we both wanted to avoid. We finally got that stuff taken care of in the past month and could make the switch.

The Zimmerman household is linked to the world, through space. Seems entirely appropriate.

Martian mountains on Mount Sharp

11:45 am

Panorama looking up Mount Sharp
Click for larger full resolution image. For original images go here and here.

Overview map
Click for interactive map.

Cool image time! The panorama above was created using two pictures taken by the high resolution camera on the rover Curiosity on Mars (here and here).

The overview map to the right gives the context. The blue dot marks Curiosity’s position on the day before these pictures were taken, climbing through the foothills on the flanks of Mount Sharp. I do not know if it traveled again before taking these two pictures above. The white dotted line its past travels, while the red dotted line its planned future route. At present Curiosity has climbed about 3,500 feet up the mountain. It is still about 15,000 feet below the peak, which is about 25 miles away and not visible from here.

The yellow lines indicate where I think the panorama is looking, though I admit that I am not sure. The view is distant, since this is high resolution camera. This panorama might actually be looking in a completely different direction, downhill at one of the hills that Curiosity previously drove past. The air is very dusty, which means if the rim of Gale Crater is in the background, 20-30 miles away, we can’t see it.

Regardless, the science team has finally finished its many nine-month-long survey of the boxwork geology, and has sent Curiosity climbing again. I think these pictures are part of their review of the future terrain, as they plan the rover’s route through the lighter-colored sulfate terrain higher on the mountain. If instead they are looking downhill, they were taken both to review previously viewed geology as well as to measure the dustiness of the atmosphere.

European Union to restructure its space bureaucracy

10:38 am

The European Union
This label would be more accurate if it read
“NOT made in the European Union”

The European Commission of the European Union (EU) announced earlier this week that it is renaming its “European Union Agency for the Space Programme” to the “European Union Space Services Agency (EUSPA)”, with the new agency aimed at running the EU’s various satellite projects, including its Galileo GPS-type constellation, its proposed communications constellations, and its various European security satellite projects.

The proposed regulatory document can be read here [pdf]. More details can be found here:

In the text of the draft regulation, the Commission says the agency is expected to play a crucial role in implementing Union space systems and wider space policy from 2028 to 2034 as part of the European Competitiveness Fund. That places the agency firmly inside the next generation of EU planning for satellite navigation, Earth observation, secure connectivity, space situational awareness and related civil and defence applications.

One of the clearest elements in the proposal is the agency’s planned renaming. The draft regulation states that the current European Union Agency for the Space Programme would become the European Union Space Services Agency. The Commission says this is meant to reflect more accurately the body’s current and future role as an operational actor supporting the delivery of Union space systems rather than simply administering a programme framework. That change in title is therefore intended to signal a broader institutional shift rather than a cosmetic rebranding.

The language above as well as the actual regulation itself I think illustrates well why the European Union is increasingly falling behind the rest of the world in space. The wording is obtuse, complex, and jargon-filled, often aimed at making things seem more significant than they really are.

The number of different bureaucracies involved is also a bad sign. On top is the EU. Under that is the European Commission. Below that is this new agency EUSPA. On the side is the European Space Agency, which though it will have a representative at all EUSPA meetings the division of responsibilities between it and EUSPA is very unclear.

All told, everything about this document and the government bureaucracies involved seems designed to do things slowly and in a manner guaranteed to cost more.

No wonder many member nations of the EU and ESA have decided to go their own way, even as they politely maintain membership in these organizations. Germany, France, Spain, and Italy are all now pushing the development of new commercial independent space companies within their borders, all attempting to launch similar space assets, but with the ability to eventually do it faster and cheaper.

I would expect those new private companies will soon eclipse anything proposed by EUSPA in the coming decade.

ESA paid Arianespace about $96 million for an Ariane-6 launch

9:24 am

According to a story today on European Spaceflight, the European Space Agency (ESA) paid its commercial division Arianespace €82 million [about $96 million] for its Ariane-6 launch in November 2025 of ESA’s Earth observation Sentinel-1D satellite.

The European Space Agency has disclosed that launching the Sentinel-1D Earth observation satellite aboard an Ariane 62 rocket in November 2025 cost €82,070,773. As part of its involvement in the development of the European Union’s Copernicus Earth observation satellite constellation, ESA is responsible for placing contracts with European industry for the development, launch, and operation of satellites. As part of this responsibility, the agency publishes an annual list of all contracts awarded with a value of more than €15,000. In 2025, this included the disclosure of the cost of launching Sentinel-1D aboard an Ariane 6 rocket in its two-booster variant [dubbed Ariane-62].

This is the first time ESA or Arianespace have revealed any price figures for using Ariane-6, and shows that Arianespace is attempting to price Ariane-6 competitively with SpaceX’s Falcon 9 rocket. The article notes that SpaceX charged ESA about $90 million for an earlier Sentinel launch.

Because Falcon 9 is mostly reusable, SpaceX’s profit margin is far higher than Arianespace’s. Ariane-6 is expendable, and thus costs more. Thus, if necessary SpaceX could significantly lower its price, but hasn’t because it hasn’t yet felt any competitive pressure to do so. When the new reusable rockets from Stoke Space and Rocket Lab begin launching sometime this year, then launch prices will drop considerably, and Ariane-6 will find itself very over-priced, with no way to lower its cost enough to compete.

Saxavord spaceport lost about $7 million in both ’23 and ’24; Andoya launch scheduled for today

9:00 am

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

According to a report in the Times of London yesterday, the Saxavord spaceport on the Shetland Islands lost about $7 million in both ’23 and ’24.

Annual accounts for Shetland Space Centre, the SaxaVord operating company, show a near 32 per cent rise in revenue to £2.5 million for 2024. The document, recently lodged at Companies House, shows a £5.4 million [$7.25 million] pre-tax loss, compared to £5.1 million [$6.85 million] in 2023.

The spaceport is controlled by billionaire Anders Holch Povlsen, who had been instrumental in using the courts to block launches from the other proposed spaceport in Sutherland, Scotland. Saxavord meanwhile was first proposed about four years ago, but it has also not yet had its first launch. In both cases, the major obstacle has been the United Kingdom’s regulatory bureaucracy run by its Civil Aviation Authority, which has taken years to issue permits and licenses. Those delays have bankrupted two rocket companies, Virgin Orbit and Orbex, because they were unable to launch as scheduled.

Saxavord hopes its first launch will occur later this year, from the German rocket startup Rocket Factory Augsburg. That company had hoped to launch in 2024 — after more than a year delay due to red tape — but an explosion during the final static fire test of the first stage ended those plans.

Meanwhile, the first orbital launch from Norway’s Andoya spaceport is now expected later today by the German rocket startup Isar Aerospace. This will be the second launch of its Spectrum rocket, the first failing just after lift-off in 2025. This second attempt had been scrubbed in January and March, and is now scheduled for 1 pm (Pacific) today. I have embedded its live stream below.

Russia’s latest plans for its post-ISS space station

8:12 am

The present Russian plans to transition from ISS to its Russian Orbital Station
Click for full resolution image.

Anatoly Zak yesterday posted the picture to the right, showing a presentation by Russian officials of Roscosmos’ latest plans for its transition from ISS to their own Russian Orbital Station (ROS). Though it is in Russian, I think I can glean from it some significant take-aways about Russia’s future space plans.

First, if these plans proceed as planned (doubtful based on Russia’s track record in the past three decades), at some point in the next four years they will attach a new module to ISS, docking with the Prichal docking hub, launched in 2021. Then in 2030 they will undock this new module as well as Prichal and the Nauka module, which also launched in 2021, and use these three modules as the core of their new station.

That 2030 date is significant, as it is an admission by Russia that it intends to stay with ISS until then. Up till now Roscosmos has only committed to ISS through 2028, even though NASA and its partners at ESA and Japan have set 2030 as ISS’s present retirement date.

Second, they plan to add more modules to this core station, beginning in 2031, and by 2034 to have completed a four-module cross-shaped station with Prichal as the central hub. That completion date is one year later than the timeline Russia announced in 2024, when it claimed ROS would be completed in 2033. That 2024 timeline also said ROS’s first module would be launched in 2027, but the graphic to the right no longer gives any date for that launch. I suspect 2027 is extremely unlikely.

Finally, don’t expect the new modules promised in the 2031-2034 timeframe to launch on schedule either. As I note above, all Russian space projects in this century have routinely been delayed repeatedly, with most never launching at all.

This plan also makes no mention of an agreement with India in December 2025 to coordinate the construction of its station with Russia’s, flying both in the same inclination presently used by ISS. This is not really a surprise, as both projects will operate independently, so that delays in one do not impact the other.

China launches 18 more Qianfan internet satellites

5:16 pm

Earlier today China successfully placed 18 more Qianfan internet satellites into orbit, its Long March 8 rocket lifting off from its coast Wenchang spaceport.

This was the seventh launch for this Starlink competitor, which is also called Spacesail or G60, bringing the total number of satellites launched to 137, out of a planned constellation of as many as 10,000. The first phase of the constellation however only requires 648. Though China hopes to reach that number before the end of this year, it will be a year late, based on the constellation’s international licensing requirement. Moreover, there have been stories suggesting this project is short of cash.

The leaders in the 2026 launch race:

42 SpaceX
17 China
5 Rocket Lab
4 Russia

SpaceX continues to lead the entire world combined in total launches, as it did in both ’24 and ’25, 42 to 31.

China was supposed to do another launch this afternoon, but as of posting there is no report announcing it.

Update on SpaceX’s Starship/Superheavy launchpad improvements at Boca Chica

9:35 am

Link here. The article provides many details about the design improvements and testing that SpaceX is doing at the Boca Chica launchpad prior to the next Starship/Superheavy orbital test flight, now expected sometime in mid-May.

All the improvements appear designed to allow for quicker reuse of the pad, including protecting it better when both Starship and Superheavy return to be captured by the chopstick towers. For example:

On the tower, work has progressed on the Ship Quick Disconnect (SQD) arm, which connects to the Starship upper stage for propellant loading. This week, technicians added steel reinforcements to the lower side of the arm’s shoulder section. These additions are believed to strengthen the structure while enabling the arm to retract more quickly during launch.

A faster swing-out reduces the risk of damage from the intense exhaust plume of Super Heavy’s 33 Raptor engines at liftoff. This improvement should minimize post-launch refurbishment and contribute to a higher launch cadence. The core work on the SQD arm itself appears largely complete, and scaffolding may soon be removed as final preparations continue.

Other work includes a new tower roof structure to protect it from the rocket’s engine exhaust, and other work on the pad itself to facilitate faster fueling. These additions have been accompanied by testing to make sure they work.

All this work appears intended to make it possible to launch frequently once the next test launch is completed.

Spanish rocket startup PLD borrows $35 million

9:27 am

The Spanish rocket startup PLD, which hopes to complete its first orbital launch of its Miura-5 rocket this year, has now obtained a $35 million loan from the European Investment Bank (EIB), in addition to the more than $400 million in investment capital it had previously raised, and a variety of government grants totaling around $200 million.

The European Investment Bank (EIB) has signed a €30 million [$35 million] venture debt loan with PLD Space, an international space transportation company headquartered in Elche, Spain, to support the final development stage of MIURA 5, the company’s rocket designed to deploy small satellites into orbit. The operation represents the EIB’s first direct investment in small launchers for the transport of satellites into space. The financing will also support scaling of PLD Space’s industrial and launch capabilities to transition toward commercial operations.

Considering how much actual capital and government grants PLD has raised, one wonders why it also needs to take out this loan. It suggests the company has cash flow issues, despite the funding obtained.

Though the company appears to be on schedule for its planned launch of Miura-5 this year from French Guiana, no launch date has been announced.

Orbital repair startup Starfish raises $100 million in private investment capital

9:13 am

Remora rendezvous
Images taken by Starfish’s camera.

The orbital servicing startup Starfish Space has now raised an additional $100 million in private investment capital, in addition to the $29 million raised previously.

Seattle-based Starfish announced April 7 it closed a Series B round led by Point72 Ventures, raising more than $100 million. Activate Capital and Shield Capital co-led the round, with major participation from Industrious Ventures and NightDragon. Several other new and existing investors were also part of the funding round.

…The company, which raised $29 million in November 2024, says the funding will enable it to scale up production of its Otter line of spacecraft designed for in-space servicing of other spacecraft. The company has won several contracts from government and commercial customers for missions to extend the lives of satellites or deorbit defunct satellites.

Starfish has already won contracts to do a variety of demo and satellite repair missions with the military (see here, here, and here) totaling about $144 million.

This financial success has occurred despite the fact that Starfish’s Otter servicing robot has yet to dock and repair any satellite. It has done two rendezvous and proximity demo missions, the second of which was supposed to do a docking but could not when the owner of the target satellite backed out of the project. The Otter-2 robot is still working in orbit, but the company has not been able to find a new target spacecraft to dock to. The company has also demonstrated its camera on another company’s orbital tug, as shown by the images above.

The Japanese orbital tug company Astroscale this week announced a 2027 mission to fly an inspector satellite to rendezvous and inspect closely two different defunct satellites in different orbits.

The ISSA-J1 mission will inspect two retired Japanese satellites launched in the early 2000s. By approaching them in orbit, ISSA-J1 will observe their current condition more than 20 years after launch, including their attitude, rotation behavior and signs of degradation. The mission will conduct close‑range observations of multiple objects, closer than traditional monitoring methods, demonstrating new possibilities for on‑orbit inspection services.

The screen capture graphic to the right shows ISSA-J1’s proximity flight path around the first defunct satellite, ALOS, which was an Earth resource satellite that operated from 2006 to 2011. After completing its inspection of ALOS, it will then move into a higher orbit to inspect ADEOS‑II, another Earth observation satellite that operated in 2003.

Astroscale has already demonstrated it can do these kinds of inspection missions with its ADRAS-J mission, which flew within fifty feet of an abandoned rocket upper stage. Its eventual goal is to do space junk removal missions, grabbing this kind of space junk and de-orbiting it.
