The Congressional Budget Office issued an updated estimate today of the cost of President Trump’s Golden Dome missile defense system. Lacking detailed data from the Administration, CBO based its analysis on the capabilities called for in Trump’s January 2025 Executive Order and concluded the total cost over 20 years is $1.2 trillion, about twice its estimate last year, with the bulk of it for Space-Based Interceptors.

Trump issued the Iron Dome for America Executive Order on January 27, 2025, seven days after his second term began. He soon renamed it Golden Dome in part to distinguish it from Israel’s Iron Dome system which has more limited capabilities. Trump appointed Gen. Michael Guetlein to lead the project and in an Oval Office meeting on May 20, 2025, said it would cost $175 billion and be completed in three years, before he leaves office.

By then CBO had estimated the cost at $524 billion based on information available at the time.

Guetlein has since raised his estimate to $185 billion, but it is widely viewed as far too low.

Several important points: First, the CBO’s cost estimates are usually wrong, in either direction, which means the cost could be a lot less, or a lot more. Odds are that in this case its estimate is trending in the right direction. Guetlein’s cost estimate is absurdly too low.

Second, the high cost helps explain why a lot of investment money is pouring into a lot of new space startups, for both rocket and satellite companies. Wall Street sees the federal government spending a lot of money on Golden Dome, and wants to get into the action. For the same reason this is why a lot of space companies have shifted their focus from civilian projects to the military.

Finally, the idea of Golden Dome is perfectly reasonable, as its concept has already been proven both by the U.S.’s Patriot missile system and Israel’s Iron Dome. The implementation however is going to be bad, because the people in Washington being asked to do it have a terrible track record. They routinely waste money and manage projects badly.

The new round will accept new submissions through 2028. The program is designed to encourage the development of private and independent rocket companies, competing for market share, with the added ability to provide ESA its needed launch services. What makes this ESA program different than all its previous rocket programs is that ESA does not own or control the rockets. It is helping to get these companies started, and will simply then be a customer buying the product from them once operation. Ownership will belong to the companies, not ESA.

To emphasize the ownership point, to get funding under this program “requires private co-funding. For every euro invested by ESA in commercial space businesses, often more than five euros are leveraged from private investors.”

So far ESA has provided funding to eleven different European startups, including Isar Aerospace, Rocket Factory Augsburg, and PLD, all three of which hope to make their first orbital launch this year. This new round is being offered to these companies and any new ones that might come forward. Of the 110 million euros so far allocated 20 million euros remains available for distribution.

In AST SpaceMobile’s 10-Q filed with the SEC on Monday, the company said the loss is expected to be in line with the carrying value of the satellite, in the range of $155 million to $160 million. The company plans for an asset write-off in the second quarter of 2026. The company also said in the 10-Q it had launch insurance coverage that covered a portion of the satellite and launch costs and has filed claims.

“At the end of the day, remember, we have 33 satellites in advanced stages of production at the factory. So it was a loss, we’re on to the next,” Wisniewski told investors. He added that the company is working closely with Blue Origin and is “optimistic” about New Glenn returning to the launch pad soon.

The company’s next launch is with SpaceX on a Falcon 9 rocket that will launch three satellites — BlueBirds 8, 9 and 10. Wisniewski confirmed the company has contracted launch capacity to meet its target of deploying 45 satellites by the end of this year. He also mentioned that five BlueBirds would fit in a United Launch Alliance Vulcan configuration, mentioning the company has been developing other heavy launch providers outside of SpaceX and Blue Origin.[emphasis mine]

The highlighted sentence suggests the company is also negotiating new contracts with both Arianespace’s Ariane-6 rocket and India’s LVM3 rocket. It has already used the latter on one launch successfully.

Nonetheless, the only company with the capability of ramping up enough launches quickly this year to meet this goal will be SpaceX. Expect that company to get more Bluebird launches in 2026.

SpaceX yesterday announced that the 12th orbital test flight of its Starship/Superheavy rocket is now scheduled for May 19, 2026, with a launch window opening at 5:30 pm (Central).

The mission will be also be the first flight of what SpaceX calls Version 3 of both the booster and the spaceship, will include the first use of the Raptor-3 engine, and the first use of a completely redesigned launchpad.

The flight test’s primary goal will be to demonstrate each of these new pieces in the flight environment for the first time, with each element of the Starship architecture featuring significant redesigns to enable full and rapid reuse that incorporate learnings from years of development and test.

The booster’s primary test objective will be executing a successful launch, ascent, stage separation, boostback burn, and landing burn at an offshore landing point in the Gulf of America. As this is the first flight test of a significantly redesigned vehicle, the booster will not attempt a return to the launch site for catch.

The Starship upper stage will target multiple in-space and reentry objectives, including the deployment of 22 Starlink simulators, similar in size to next-generation Starlink satellites. The last two satellites deployed will scan Starship’s heat shield and transmit imagery down to operators to test methods of analyzing Starship’s heat shield readiness for return to launch site on future missions. Several tiles on Starship have been painted white to simulate missing tiles and serve as imaging targets in the test. The Starlink simulators will be on the same suborbital trajectory as Starship. A relight of a single Raptor engine while in space is also planned.

As an added potential test-to-failure, the company has also removed a single heat shield tile to test how Starship performs under this failure scenerio. The flight plan will be the same as the previous flights, designed to come down in the Indian Ocean.

A detailed description about the upgrades to Starship, Superheavy, and the ground systems can be found here.

The company will broadcast the launch live, which I will embed on Behind the Black once available.

In a tweet yesterday SpaceX sort of confirmed the rumor reported here last week that it is considering purchasing a giant 200-plus square mile plot (about 136,000 acres) on the south coast of Louisiana near the unincorporated town of Pecan Island.

It’s no secret that we intend to launch Starship a lot, targeting thousands of flights per year. That cadence will require the ability to launch from many different locations, so we are constantly exploring to find viable sites to expand Starship operations in the future, both domestically and internationally

This comment was in response to a tweet touting this rumor. Note that SpaceX’s comment is somewhat vague. It says the company is searching for additional launch locations for Starship, but does not say specifically if this Louisiana plot is one of them.

I suspect it is, based on all the known facts. The company is just being coy, likely because negotiations are still on-going. If so, the tweet tells us that if purchased SpaceX intends to use the site as a future spaceport. And because of its size, it will likely also install Raptor-3 engine test stands as well as its planned data-center satellite manufacturing, consolidating some operations in one location.

As expected, the science team for the Mars rover hasdecided before moving on it would take a close look at the 28 pound slab of rock that had been stuck on its drill bit and when finally dropped free broken into several pieces when it hit the ground.

The top picture to the right, cropped and reduced to post here, shows that entire rock, labeled Atacama by the science team. The two insets below are close-ups of the delicate layering at the rock’s left edge as well as the drill hole itself. From team’s update today:

The highest-priority activities after liberating the drill included imaging the drill with Mastcam and ChemCam RMI, and imaging into the now-empty drill hole with MAHLI (the image above). The science team made the most of the freshly-broken surfaces created when Atacama fell back to Mars, and the freshly-exposed sand once hidden underneath Atacama.

The exposed sand is off camera, to the right. Expect a paper published about that sand, buried likely for millions of years, sometime in the next year or so.

The delicate flutes at the rock’s left edge are somewhat common rock features seen by Curiosity, made possible by Mars’ thin atmosphere and its one-third Earth gravity. On Earth the gravity and weather generally destroys such things. On Mars the lack of violent weather and light gravity allows them to form, and the thin wind even helps in their formation.

We don’t know if these data centers will be part of a SpaceX/Google partnership, or whether Google is merely negotiating a SpaceX launch deal to place its own data centers in orbit. Nor do we know if this deal will use SpaceX’s Falcon rockets, or is aimed at using Starship when operational. Neither would surprise me. Nor would it be surprising if both occur.

The story is in linked to SpaceX’s impending initial public stock offering (IPO), expected to the biggest in history.

The German aerospace company OHB has now joined with France’s Dassault Aviation in its project to build Vortex, a reusable mini-shuttle that could be used to supply cargo to the future commercial space stations presently under development.

An initial subscale demonstrator of the spaceplane, called the VORTEX-D, is being developed by the company with support from the French Ministry of the Armed Forces. During a 25 June 2025 hearing of the French National Assembly’s Committee on National Defence and the Armed Forces, it was revealed that the demonstrator is expected to be launched in 2028 and has a total project cost of €70 million, with Dassault providing more than half of the funding and the remainder coming from the French government.

The VORTEX-S is expected to follow the VORTEX-D demonstrator. This larger, more complex variant will be developed in partnership with OHB following the finalisation of the 11 May agreement, as the companies seek to secure ESA backing for the project. According to the release announcing the partnership, discussions are also underway with other major European space companies to “expand the team.”

Dassault will remain the lead contractor, building the mini-shuttle. OHB will build the service module. The hope is that later versions of Vortex could also ferry crews to and from space.

This project started in 2023, and initially hoped to do the first test mission to ISS in 2026. That test flight is now targeting 2029, with later missions slipping beyond 2031 and now targeting missions to one of the new stations replacing ISS.

The first stage completed its 9th flight, landing on a drone ship in the Pacific.

Next China launched another set of Qianfan (SpaceSail) internet satellites into orbit, its Long March 6A rocket lifting off from its Taiyuan spaceport in northeast China. Though China’s stage run press did not reveal the number of satellites launched, past Long March 6A launches of this constellation have placed 18 satellites into orbit. If so, there are now 155 Quinfan satellites in space, out of a planned constellation of as many as 10,000. The first phase of the constellation however only requires 648, which China hopes to reach before the end of the year.

The state-run press also did not reveal where the rocket’s lower stages (using very toxic hypergolic fuels) crashed inside China.

For the third straight year SpaceX leads the entire world combined in total launches, 56 to 46.

SpaceX hopes to complete another launch later today, carrying a Dragon cargo capsule to ISS (on its sixth flight), but weather might force a scrub. UPDATE: Scrubbed due to weather, rescheduled for May 13, 2026.

Cool image time! The picture to the right, cropped and rotated so that north is to the top, was taken on March 28, 2026 by the high resolution camera of Mars Reconnaissance Orbiter (MRO).

It shows what the science team labels a “south polar residual cap site.” The location is about 200 miles from the Martian south pole, well within the south polar ice cap. A second picture of this same spot was taken only a few days later, and was labeled “bright and dark fans on patterned ground.” With the second image the science team added their nickname for this location, “Troy,” which makes referencing it easier.

The hatchwork is the mystery here. In fact, the scientists have been monitoring this geology since 2020 to see if there have been any changes, either long term or seasonally. Almost certainly they have spotted seasonal changes, as indicated by the hatchwork itself and explained below, but I don’t access to the higher resolution images that would show any major modifications on a larger scale.

The black dot on the overview map to the right marks the location of this strange hatchwork, on a section of the white perennial cap of ice and dry ice that sits over Mars’ south pole.

So what causes this hatchwork? At both Martian poles carbon dioxide falls as snow in the winter to form a thin mantle of dry ice that then sublimates away in the spring. That sublimation process however starts at the base of the mantle. As the solid dry ice turns to gas, pressure builds, until the mantle cracks at weak points so that the gas can escape.

For reasons that are not yet explained, this process is different between the north and south poles. In the north the breakage and release happens at random and different points from year to year. At the south pole it instead repeats along the same weak points each year, producing permanent features that resemble spider webs. This is what I think we are seeing here. This hatchwork marks those weak points, where the mantle is cracking to let the sublimating gas escape.

At least, that is what I think is happening here, based on past discussions with planetary scientists and my reading of their papers. It is very likely however that some other process is involved, either newly discovered or completely inexplicable.

The asteroid probe Psyche is now approaching Mars for a May 15, 2026 fly-by that will slingshot it out to the metal asteroid Psyche in 2029.

The image to the right, cropped and expanded to post here, was taken on May 3, 2026 when the spacecraft was still about three million miles away.

The observation was acquired by the multispectral imager instrument’s panchromatic or broadband filter, with an exposure time of just 2 milliseconds. Even with this very short exposure time, the crescent is extremely bright and parts of the image are oversaturated. The light seen here is sunlight reflected off the surface of Mars and also scattered by dust particles in its atmosphere. Because the quantity of dust in the atmosphere can vary rapidly over time, the anticipated brightness of the crescent was hard to predict before this early image was acquired.

The dustiness of Mars leads to sunlight being scattered by its atmosphere, making the crescent appear to extend farther around the planet than if it had no atmosphere (as with our Moon).Of note, on the right side of the extended crescent, there appears to be a gap, which coincides with the planet’s icy north polar cap. The cap is currently in winter and mission specialists hypothesize that seasonal clouds and hazes may be forming in that region, possibly blocking the atmospheric dust’s ability to scatter sunlight like it does elsewhere around the planet.

Though the spacecraft had had a thruster issue last year, all seems well at this time.

China hopes to keep this cargo freighter in orbit for a full year, as part of its effort to reduce the number of cargo missions per year while expanding the capabilities of its spacecraft and station.

For the third straight year SpaceX leads the entire world combined in total launches, 55 to 45.

The space station startup Vast earlier this week signed an agreement with Lithuania to work together on future space missions, either to ISS or its Haven-1 single-module station scheduled for launch next year.

Under the agreement, Vast and Innovation Agency Lithuania will explore opportunities for joint scientific research activities either in the International Space Station National Lab or Haven-1, scheduled to be the world’s first commercial space station, launching in 2027. The partnership also includes plans to further develop educational programs in Lithuania and deepen engagement with local industry.

This deal is similar to Vast’s earlier deals with the European Space Agency, the Czech Republic, Colombia, Uzbekistan, Japan, and the Maldives. All are structured so that should Haven-1 reach orbit and be proven operational and safe for occupancy, these countries could consider sending their own astronauts on missions there. All thus show there is an international market for a private space station, a market that Vast is working hard to capture.

In other space station news, Voyager Technologies, the lead company building the Starlab station, released its 2026 first quarter fiscal report, indicating a solid financial position resulting from its diversification into military-based space applications. Though the report notes that “Starlab does not generate revenue today, nor is expected to generate revenue in the near term,” the company’s overall strength lays a strong foundation for that station’s eventual construction.

In my rankings below of the five stations under development, these two stations remain essentially tied for first place, with Axiom a close third.

• Haven-1 and Haven-2, being built by Vast, with no NASA funds. The company plans to launch its single module Haven-1 demo station in 2027 for a three-year period during which it will be occupied by at least four 2-week-long manned missions. It also plans a manned mission to ISS in ’28. The company has already tested an unmanned small demo module in orbit. It has also made preliminary deals with Lithuania, Colombia, Uzbekistan, Japan, the Czech Republic, and the Maldives for possible astronaut flights to Haven-1. It has also raised more than a billion in cash for this work.
• Starlab, being built by a consortium led by Voyager Space, Airbus, and Northrop Grumman, with extensive partnership agreements with the European Space Agency, Mitsubishi, and others. Though no construction has yet begun on its NASA-approved design, it has raised $383 million in a public stock offering, the $217.5 million provided by NASA, and an unstated amount from private capital. It has also begun signing up station customers, as well as a number of companies to build the station’s hardware. It also plans a mission to ISS in ’28.
• Axiom, being built by Axiom, has launched four tourist flights to ISS, with the fourth carrying government passengers from India, Hungary, and Poland. A fifth mission is now planned for ’27. The company has now raised $450 million in private investment capital. Thales Alenia in Europe has been building its first two modules, with the first to launch in 2028 (though recent rumors of corrosion issues might cause a delay). It has also signed Redwire to build that module’s solar panels.
• Thunderbird, proposed by the startup Max Space. It is building a smaller demo test station to launch in ’27 on a Falcon 9 rocket, and has begun work on its manufacturing facility at Kennedy in Florida. Its management includes one former NASA astronaut and one former member of the Bigelow space station team that built the first private orbiting inflatable modules, Genesis-1, Genesis-2, and BEAM (still operating on ISS).
• Orbital Reef, being built by a consortium led by Blue Origin and Sierra Space. This station looks increasingly dead in the water. Blue Origin has built almost nothing, as seems normal for this company. And while Sierra Space has successfully tested its inflatable modules, including a full scale version, its reputation is soured by its failure in getting its Dream Chaser cargo mini-shuttle launched to ISS.

The orbital servicing startup Katalyst has now successfully completed the final ground testing of its Swift rescue spacecraft, dubbed LINK, that it hopes will be able to catch the Gehrels-Swift Telescope and raise its orbit, thus saving the telescope.

During vibration testing at NASA Goddard, engineers mimicked the shaking the spacecraft will experience during its launch from a Northrop Grumman Pegasus rocket. In the footsteps of Swift itself and NASA’s upcoming Nancy Grace Roman Space Telescope, the Katalyst team also used NASA Goddard’s Space Environment Simulator for thermal vacuum testing.

Once the air was pumped out of this 27-foot-wide chamber, LINK experienced space-like hot and cold temperature extremes. The team also practiced firing the satellite’s three xenon-powered ion thrusters and deployed one of the arms.

After some more testing in Arizona, the spacecraft will be integrated in June onto Northrop Grumman’s Pegasus rocket — the last one in its inventory — and launched later that month.

Katalyst has never done this before. It was preparing LINK as a demo mission when NASA requested bids for saving Swift. It proposed reconfiguring LINK for that purpose, and won the contract in September 2025, only eight months ago.

If this mission succeeds it will be a big feather in Katalyst’s cap.

• Stoke Space shows off the interior of its Nova rocket’s first stage tank
  The company is “putting the finishing touches on our integration campaign,” which suggests it is getting very close to that first launch. No date has been set however.

• On this date in 1992 the space shuttle Endeavour launched on its first mission.
  The mission captured and repaired the Intelsat-6 F3 communications satellite, in one of the most daring captures of the entire shuttle program. The original plan to catch didn’t work, so the crew ended up sending three astronauts out in the cargo bay to grab and hold it while one got it attached.

• On May 8, 2004 the European Space Agency (ESA) did the first helicopter drop glide test of Phoenix, a prototype of a proposed orbital and reusable launch vehicle
  Dropped from 8,000 ft by a helicopter, it landed precisely and without incident after a GPS-guided 90 second glide. More than two decades later, ESA has done nothing to follow up this test flight.

Lunar Outpost, the leader in off-planet mobility and in-space infrastructure, today announced a $30M Series B led by Industrious Ventures, with participation from Type One Ventures, Eniac Ventures, Promus Ventures, Reliable Equity, and others. The capital injection accelerates production and deployment of the company’s advanced robotics and mobility platforms as it scales the critical industrial layer required for a permanent human presence in space.

The company started out competing for NASA’s initial planned contract to build a manned lunar rover, proposing its “Eagle” rover and even signing a contract with SpaceX to deliver it to the Moon on Starship. Since then it has developed and successfully tested an autonomous excavator, dubbed Owl, while expanding its product line beyond rovers.

Rocket Lab announced yesterday that it has won a big new launch contract with an undisclosed customer for three launches of its Electron rocket and five launches of its new Neutron rocket.

The multi-launch agreement includes five dedicated Neutron launches and three dedicated Electron launches baselined to launch between 2026 and 2029. The missions will lift-off from both Rocket Lab Launch Complex 1 in New Zealand and Rocket Lab Launch Complex 3 in Virginia. Pricing for these launches aligns with Rocket Lab’s average selling price for Neutron and Electron. The remaining terms of the deal are undisclosed.

Based on the known average launch prices for these rockets, this deal is likely worth somewhere between $250 million to $300 million. That a customer was willing to purchase five launches of Neutron before the rocket has even launched is also a strong statement of confidence in Rocket Lab itself. The company hopes to do the first test launch of Neutron before the end of this year.

Rocket Lab also made a slew of other announcements yesterday. The company will be partnering with Anduril as part of its 20-launch contract with the War department to use its suborbital HASTE version of its Electron first stage for hypersonic testing. The deal involves three of those twenty launches.

The company also announced a partnership with Raytheon to “demonstrate advanced capabilities for the United States Space Force’s Space Based Interceptor program.” Rocket Lab also revealed it is acquiring the California robotic company Motiv Space Systems that has built equipment used on the Mars rover Perseverance.

Rocket Lab might not be as big as SpaceX, but it has unquestionably been as successful in its own way.

In response to the story earlier this week that SpaceX might be acquiring a 200-plus square mile patch of land near Pecan Island on the southern coast of Louisiana, a state senator has now confirmed that two unnamed aerospace companies have been talking with landowners about a possible purchase.

State Sen. Bob Hensgens, R-Abbeville, said he knows of two companies — he did not reveal if it is Elon Musk-owned SpaceX or Jeff Bezos’ Blue Origin — that have reached out to landowners in coastal Vermilion and Cameron parishes about a possible acquisition. “I know both companies are trying to find property in southwest Louisiana,” Hensgens said. “I know from people in the parishes that the companies have made outreach in the area.”

If so, we might actually have a bidding war for this property. Note however that nothing has yet been confirmed, including the names of the companies involved. The article at the link however provides some background into the 136K acre plot owned by Exxon, and how it might now be for sale. It also reports that a number of legislators (not Hensgens) have signed non-disclosure agreements about the negotiations.

Engineers from JPL and the aerospace company AeroVironment have been testing a new set of high speed rotors that they hope to use on the next generation Mars helicopters, designed to increase their payload capacity by as much as 30%.

The rotors of Ingenuity — the first helicopter to fly on Mars — never spun faster than 2,700 rpm, because at faster speeds it would be approaching the speed of sound (on Mars), when unpredictable things could happen. Engineers are pushing those limits with these new rotors, in a chamber mimicking the thin Martian atmosphere.

The test engineers had taken the precaution of lining part of the chamber with sheet metal in case the blades broke apart during the supersonic experiment. From a control room a few yards away from the chamber, the team watched displays showing data and a view inside the chamber as the rpm climbed as high as 3,750. At that rate, the tips were traveling at Mach 0.98 [just under the Martian speed of sound]. Then the engineers activated a fan inside the chamber that pelted the rotors with headwinds. After each run, they increased in wind velocity for the next run.

The team pushed rotor tip speeds to Mach 1.08, boosting the Mars vehicle’s lift capability by 30%. This breakthrough allows future missions to support heavier scientific payloads, including advanced sensors and larger batteries for extended flight. Next the team tried their luck with the two-bladed SkyFall rotor. Because it is slightly longer than the three-bladed version, only 3,570 rpm was needed to achieve the same near-supersonic speed at the rotor tips prior to introducing the headwinds.

NASA administrator Jared Isaacman has said he wants to send a fleet of helicopters to Mars in 2028, on that first nuclear-powered mission. Whether or not that mission happens as he proposed, there is ample evidence scientists plan on sending more helicopters there in the next few years (see here, here, here). These tests lay the groundwork for those future missions.

Paraguay yesterday became the 67th nation to sign Artemis Accords, continued the flood of smaller third world nations that have signed up in the last few weeks following the completion of the Artemis-2 mission around the Moon.

The remarks of NASA administration Jared Isaacman in connection with this event I find most tantalizing:

“They join an ever-growing coalition of like-minded nations committed to the peaceful, transparent, and responsible exploration of space. Established by President Trump in his first term, the Artemis Accords provided the principles for how we explore the Moon, Mars, and beyond. Now, with his national space policy, we are putting the Artemis Accords into practice with our Moon Base. We are creating opportunities for all Artemis Accords signatories, including Paraguay, to join us on the lunar surface and advance our shared objectives in this next era of exploration.” [emphasis mine]

While that national space policy [pdf] accepts the Outer Space Treaty’s limitation on establishing American law on other worlds, including property rights, it also makes its first goal that of promoting private enterprise.

Promote and incentivize private industry to facilitate the creation of new global and domestic markets for United States space goods and services, and strengthen and preserve the position of the United States as the global partner of choice for international space commerce.

Repeatedly the policy emphasizes the importance of private enterprise, with one whole section devoted to outlining ways to encourage commercial non-governmental activities in space.

Isaacman’s statement yesterday is the first time in years that any NASA official has focused on this issue in any way. Trump originally created the Artemis Accords as a first step to overcome the Outer Space Treaty’s ban on private property in space. The thinking appeared to be: Make a large American alliance that would eventually have the clout to change that ban.

During the Biden administration that goal was dumped and was replaced with using the accords to encourage global collectivism. It appears Isaacman is very carefully returning to that original goal, laying out the initial political steps for doing what Trump first wanted the accords to accomplish. He is clearly indicating here that the American moon base will function under an American legal framework, even if initially for diplomatic reasons no one will make that obvious.

The full list of nations in this American space alliance is as follows:

Angola, Argentina, Armenia, Australia, Austria, Bahrain, Bangladesh, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Ireland, Israel, Italy, Japan, Jordan, Latvia, Liechtenstein, Lithuania, Luxembourg, Malaysia, Malta, Mexico, Morocco, the Netherlands, New Zealand, Nigeria, Norway, Oman, Panama, Paraguay, Peru, Poland, Portugal, Romania, Rwanda, Saudi Arabia, Senegal, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the Philippines, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

With this signing, the only South American nations that have not signed are Bolivia, Venezuela, Guyana, Suriname, and French Guiana (though French Guiana could be considered a signatory under France).

Though the Jupiter orbiter Juno is in its final orbits as it is running out of fuel, on May 1, 2026 it did a close fly-by of the 50 by 72 mile-wide Jupiter moon Thebe, getting within 3,100 miles.

The picture to the right, cropped and expanded to post here, is the best image released from that fly-by. It is very comparable to a photo taken by the Galileo orbiter on January 4, 2000. Both show the very large crater, dubbed Zethus.

The picture was taken by Juno’s Stellar Reference Unit (SRU) camera, designed not to do science but to “image star fields for navigation.” Thus, the picture is somewhat fuzzy, and was pointed poorly so the moon is on the far right, almost off camera.

It is very unclear how much longer Juno will function. It has apparently survived attempts by the Trump administration to zero out its operating budget, but there have been indications that its fuel supply is low.
