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 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.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

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.

Astroscale to fly mission to rendezvous and inspect two different satellites

8:01 am

Screen capture of ISSA-J1 operations around ALOS
Click for full animation.

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.

Orion completes short 15-second burn to refine its return-to-Earth

8:10 pm

The Earth as seen from behind the Moon
The Earth as seen from Orion just before the capsule swung behind
the Moon yesterday. Click for this and other Artemis-2 lunar images.

The Orion capsule today completed a 15-second engine burn in order to fine-tune its return path for splashdown in the Pacific Ocean on April 10th.

At 8:03 p.m. EDT, the Orion spacecraft, named Integrity, ignited its thrusters for 15 seconds, producing a change in velocity of 1.6 feet-per-second and guiding the Artemis II crew toward Earth. NASA astronaut Christina Koch and CSA (Canadian Space Agency) astronaut Jeremy Hansen reviewed procedures and monitored the spacecraft’s configuration and navigation data.

During today’s mission status briefing, NASA officials shared the first images received from the crew during the lunar flyby and confirmed that the USS John P. Murtha has left port and is headed to the midway point toward the recovery site in the Pacific Ocean.

This was Orion’s second small engine burn since it left Earth orbit on April 2, 2026. Unlike the Apollo missions to the Moon in the 1960s-1970s, which involved entering and leaving lunar orbit and doing complex maneuvers while there, the Artemis-2 mission around the Moon has largely been a passive one. The capsule was sent on this course at the start, and has been coasting since. Today’s burn was merely a small adjustment, not a major burn.

The re-entry on April 10, 2026 remains the key moment of the flight, as it has always been. Will that questionable heat shield do as NASA’s engineers predict and work to protect the four astronauts during re-entry? Or will it do things unexpected, because those engineers really don’t understand the engineering issues involved?

I am hopeful and optimistic. I also know that even if everything turns out fine, this flight will simply be a demonstration that NASA has learned nothing from the Challenger and Columbia accidents, and is still willing to risk human lives in order to win some political kudos and get some good PR. And for that reason I am not confident of the agency’s ability to truly do what it says, safely and competently.

One more note: Though the images being sent back are quite beautiful, they are hardly ground-breaking. Lunar Reconnaissance Orbiter has mapped the entire surface of the Moon at much great resolution, far better than anything seen on this mission. NASA might claim the astronauts are doing science, but most of it is minor and not very significant. When you get down to it, this is simply a very expensive tourist trip for four government employees, paid for at an ungodly cost by the American taxpayer.

Feathery eroding layers on Mars

Feathery layers on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and enhanced to post here, was taken on February 23, 2026 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the science team calls “layers exposed around [a] streamlined feature”.

The elevation difference between the mesa top on the left and the canyon floor on the right is about 1,000 feet. The layers are the terraces stepping downward along that drop.

What makes these layers interesting is how they have been exposed. The material that makes up the layers appears very sandy and delicate, so it breaks away it very small pieces, just like sand on a beach. The result is this feathery look. If you look close you can see that some small craters have been partly obliterated by that erosion, with their existence only marked by their remaining rim, on the high side.

Northrop Grumman’s Minotaur-4 rocket launches three payloads for War Department

8:40 am

Northrop Grumman early this morning successfully placed three experimental payloads into orbit for the War Department’s Naval Research Laboratory (NRL), its Minotaur-4 rocket lifting off from Vandenberg Space Force Base in California.

NRL’s payloads included the Lasersheet Anomaly Resolution and Debris Observation (LARADO) instrument; the Global Navigation Satellite System (GNSS) Orbiting Situational Awareness Sensor (GOSAS); and the Gadolinium Aluminum Gallium Garnet (GAGG) Radiation Instrument (GARI-1C).

The first is testing new methods for tracking space junk, the second improved GPS-type location and navigation for military operations, and the third new gamma-ray detection technology for tracking nuclear tests.

This was Northrop Grumman’s first launch in 2026, so the leader board for the 2026 launch race remains unchanged:

Firefly signs deal with modular sea launch startup Seagate

8:02 am

The startup Seagate, which is building a modular sea launch platform for any rocket company, has now signed a partnership deal with the rocket company Firefly to jointly develop that sea platform.

Seagate Space Corporation announced today a Memorandum of Understanding (MOU) with Firefly Aerospace to collaborate on the development of an offshore launch platform that enables a sea-based launch capability for Firefly’s Alpha rocket. This collaboration marks a significant milestone in expanding responsive, resilient launch solutions for the rapidly growing space economy.

Under the MOU, Seagate Space is working closely with Firefly to mature the design of an integrated offshore launch system capable of supporting the unique requirements of liquid-fueled orbital rockets. Central to this development is the integration of Seagate Space’s Gateway Series, the industry’s first purpose-built offshore spaceport designed specifically for launch operations.

Firefly presently has one operational launchpad, at Vandenberg, though it has a deal to launch its Alpha rocket from Sweden’s Esrange spaceport as well as a lease for a pad at Cape Canaveral. It has also been studying launching from a proposed commercial spaceport in northern Japan. Apparently, the company wants more spaceport options, and a sea platform gives it the most flexibility.

Cracked bedrock on Mars?

2:01 pm

Cracked Martian landscape
Click for full image.

For today’s cool image we return to Mars. The picture to the right, cropped and brightened to post here, was taken on December 3, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The focus of the picture was a strange crater in the floor of Mawrth Vallis, a channel that drains northward from Mars’ cratered southern highlands to its northern lowland plains. You can see the crater in the full image if you click on the picture. It is intriguing because its rim is strangely abrupt and flat on all sides, something that is not seen with impact craters, which have a raised rim of material plowed out by the impact.

In the picture to the right I have however focused on the two small 50-70-foot-high mesas and cracked ground that surrounds them. What struck me was the dry appearance of this landscape. Located at 23 degrees north latitude, it is in the dry tropics of Mars, where little near surface ice is found. The cracks emphasize this conclusion, as they so well resemble the cracks you see in dried mud on Earth.

Orion completes small mid-course-correction engine burn as it prepares to swing around behind the Moon

9:41 am

The Moon as seen by Orion's astronauts
The Moon as seen by Orion’s astronauts on April 4th, cropped
and reduced to post here. Click for original image.

NASA’s manned Orion capsule last night completed small mid-course-correction engine burn to refine the spacecraft’s trajectory around the Moon and back to Earth.

Mission control teams in Houston and the Artemis II crew completed an outbound correction burn to refine the Orion spacecraft’s trajectory to the Moon. The burn began at 11:03 p.m. EDT and lasted 17.5 seconds. NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with CSA (Canadian Space Agency) astronaut Jeremy Hansen, continue on a precise path to flyby the Moon on Monday, April 6.

The lunar fly-by is scheduled for this evening. As the capsule swings around behind the Moon, there will be a communications black-out from 6:44 pm (Eastern) to 7:25 pm (Eastern). NASA is making a concerted PR effort to compare this to the Apollo 8 mission around the Moon, but the differences are gigantic. Apollo 8 went into orbit around the Moon. There was considerable risk it could get stuck there if its engine failed to fire properly when behind the Moon on its last orbit. Thus, that Apollo 8 blackout was quite tension-filled.

Orion’s fly-around is instead completely benign. They aren’t going into orbit, and they are already on their path back to Earth. There will be no extra element of risk as they fly behind the Moon. All they will be doing is coast along, as they have been doing since leaving Earth orbit. They will simply be out of touch for about 40 minutes.

I sadly remain personally bored by this mission. It is is testing relatively little new engineering for future use, and is mostly designed as a PR stunt to convince everyone that “NASA is back!” Hardly. The capabilities of SLS and Orion are extremely limited, and both are ungodly expensive. Neither will make possible any colonization of the solar system. All they do is act as a jobs program for government employees.

And there still remains this mission’s biggest moment of danger, re-entry and splashdown, using Orion’s questionable heat shield that did not behave properly on its only previous unmanned mission in 2022.

Japan’s lunar lander startup Ispace wins contract with Korean rover startup

9:18 am

Artist rendering of Ispace’s Ultra lunar lander

The Japanese lunar lander startup Ispace has won a new customer for its next attempt to soft-land on the Moon, with the South Korean startup Unmanned Exploration Laboratory (UEL) signing a contract to put its proposed two-wheeled rover on that mission.

Under the terms of the agreement, the UEL rover will be integrated as a commercial payload on ispace’s ULTRA lunar lander for Mission 3, currently scheduled to launch in 2028. The mission would mark the first Korean rover to explore the Moon’s surface and underscores the growing commercial collaboration between Japan and Korea in the aerospace industry.

Mission 3 will serve as the inaugural flight for ispace’s ULTRA lunar lander.

Ispace so far has a very mixed record. It has successfully gotten two landers to the Moon, but both failed just before landing. It has also recently had to delay its lander mission for NASA because it had to replace the lander’s engine, the previous engine found to be inadequate.

Ultra is Ispace’s new larger lander design, intended to fly on all future missions. It remains untested in flight. The company presently has lander contracts for the following missions:

  • 2028: a Japanese mission funded by Japan’s Ministry of Economy, Trade and Industry
  • 2029: a Japanese mission funded by Japan’s Space Strategy Fund (designed at encouraging the private space sector
  • 2030: NASA’s mission, being built in partnership with the American company Draper

At the moment, everything about Ispace remains tentative. It needs to finally land something on the Moon to truly establish itself.

Japanese rocket startup Interstellar gets another $47 million grant from Japan

8:58 am

The Japanese rocket startup Interstellar last week announced it has been awarded a new $47 million grant from Japan’s Small Business Innovation Research (SBIR) program, in addition to the $53 million awarded in earlier grants.

The SBIR is a 3-phased governmental program aimed to promote the implementation of advanced technologies developed by startups in Japan. Interstellar was selected in September 2023 under the space section focused on the “Development and Demonstration of Private Launch Vehicles”, a project spanning for 5 years, from September 2023 to March 2028. After being selected as one of the four participating companies, Interstellar became one of three companies to pass the Phase 1 review in September 2024.

In this latest round, Interstellar is one of only two companies to pass, moving into the 3rd and final phase, which includes flight demonstration. Including the funds of the previous phases the total amount has reached a maximum of 15.4 billion JPY ( 98.97 million USD).

The company has also raised a little under $130 million in private investment capital, and has also signed contracts placing seven satellites on the first launch of its proposed Zero rocket. That launch was originally supposed to occur in 2025, but did not. No new launch date has been set, though this new grant suggests the company is getting close, though I also doubt it will occur in 2026.

At the moment Japan has no launch capability, as the two rockets controlled by its space agency JAXA are both grounded due to launch failures. It has several startups trying to build their own rockets, but none has succeeded as yet. The only one to attempt a launch, Space One, has tried three times to reach orbit with its Kairos rocket, all failures.

Avio delays next Vega-C launch due to “technical issue”

8:40 am

The Italian rocket company Avio announced yesterday that is has postponed the May 9, 2026 launch of the European Space Agency’s (ESA) Smile solar wind spacecraft due to “a technical issue” discovered by a subcontractor in a component used by the Vega-C rocket.

The press release provided little information:

The launch of the Smile satellite has been postponed, due to a technical issue occurred on a subsystem component production line after VV29 launcher integration. Additional investigations are needed to exclude any relation between such issue and the VV29 launcher in order to safeguard flightworthiness. The new launch date will be announced following the completion of these activities, as agreed with the supplier.

This launch will be the first entirely managed by Avio since it regained control of its rockets from ESA’s Arianespace division. The rocket itself was grounded for two years in 2023 and 2024 due to nozzle issues. It has since flown four times successfully.

ULA launches 29 Leo satellites for Amazon

8:31 am

ULA early this morning successfully placed 29 Leo satellites for Amazon’s internet constellation, its Atlas-5 rocket lifting off from Cape Canaveral Space Force station in Florida.

This was the heaviest Atlas-5 payload so far launched by ULA, and ULA’S fifth launch for Amazon’s Leo constellation, which now has 241 satellites in orbit, out of the 1,616 it needs to launch by July 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.

ULA is in the process of retiring the Atlas-5 rocket. It now has only nine Atlas-5 rocket left in stock, with three reserved for Leo launches and six for Boeing’s Starliner manned capsule (though there is a good chance some if not all of the Starliner launches will be switched to other payloads).

This was also ULA’s second launch in 2026, which means the leader board for the 2026 launch race remains unchanged:

41 SpaceX
16 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.
