The space station startup company Vast has now signed up three more customers to fly payloads on its first space station, Haven-1, due to launch now in the spring of 2026 on a 30-day-long private commercial manned mission.

Vast announced April 8 that Japan Manned Space Systems Corporation (JAMSS), Interstellar Lab and Exobiosphere will fly research payloads on the Haven-1 station launching no earlier than May 2026. They join Redwire and Yuri as payload partners for the station.

JAMSS, which has supported research on Japan’s Kibo module on the International Space Station, will provide a multi-purpose payload facility for microgravity research on Haven-1. Interstellar Lab, a French company, will provide an advanced life sciences research facility called Eden 1.0 that will be used for experiments such as plant growth. Exobiosphere, based in Luxembourg, will fly a biotechnology payload to perform pharmaceutical and healthcare experiments.

The company says it still has one or two payload racks available for additional customers, suggesting that it is finding enough demand to justify profitable commercial operations.

Below are the four private space stations presently under development, with those I consider the most advanced in development ranked first:

  • Haven-1, being built by Vast, with no NASA funds. The company is moving fast, with Haven-1 to launch and be occupied in 2026 for a 30 day mission. It hopes this actual hardware and manned mission will put it in the lead to win NASA’s phase 2 contract, from which it will build its much larger mult-module Haven-2 station..
  • Axiom, being built by Axiom, has launched three tourist flights to ISS, with a fourth scheduled for this spring, carrying passengers from India, Hungary, and Poland. Though there have been rumors it has cash flow issues, development of its first module has been proceeding more or less as planned.
  • Orbital Reef, being built by a consortium led by Blue Origin and Sierra Space. Though Blue Origin has apparently done little, Sierra Space has successfully tested its inflatable modules, including a full scale version, and appears ready to start building the station’s modules for launch.
  • Starlab, being built by a consortium led by Voyager Space, Airbus, and Northrop Grumman. It recently had its station design approved by NASA.

China launches another technology test communications satellite payload

10:52 pm

China today successfully launched a test technology satellite for doing “multi-band and high-speed communication technology validation tests, possibly for future large internet/communications constellations, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China.

No word on where the rocket’s lower stages and four strap-on boosters, all using very toxic hypergolic fuels, crashed inside China.

The leaders in the 2025 launch race:

40 SpaceX
19 China
5 Rocket Lab
5 Russia

SpaceX still leads the rest of the world in successful launches, 40 to 33.

Curiosity climbs into a new Martian canyon

1:41 pm

Overview map
Click for interactive map.

Cool image time! The Curiosity science team has finally completed the rover’s climb up one canyon on the flanks of Mount Sharp and crossed over into a second, switch-backing up through a gap they have dubbed Devil’s Gate.

The panorama above, created from three pictures taken by Curiosity’s left navigation camera on April 9, 2025 (here, here, and here) looks south from that gap. On the horizon about 20-30 miles away can be seen the rim of Gale Crater. From this position the floor of the crater is almost out of side, blocked by the foothills on the lower flanks of Mount Sharp.

Though the ground in this new canyon (on the left of the panorama) continues to be amazingly rocky and boulder strewn, it is actually more benign that the canyon Curiosity has been climbing for the past six weeks.

The blue dot on the overview map to the right marks Curiosity’s present position, with the yellow lines indicating the approximate direction of the panorama. The rover’s next major geological goal is the boxwork to the southwest. In order to get to it quickly the science team decided to abandon its original planned route, indicated by the dotted red line, and climb upward through these canyons.

Chinese scientists say the lunar far side appears drier than the near side

10:17 am

Map of water measurements of lunar samples
Click for original image.

Based on a comparison of samples brought back by two Chinese unmanned lunar landers, Chinese scientists believe the lunar far side contains far less water in its mantle than the near side.

…the research team focused on analyzing water content and hydrogen isotopes in melt inclusions and apatite within [Chang’e-6] mare basalts—the first samples returned from the farside SPA Basin.

The team’s results indicate that the parent magma of these basalts contain 15–168 μg.g⁻¹ of water. Additionally, the team estimated that the mantle source of the CE6 basalts has a water content of 1–1.5 μg.g⁻¹, significantly lower than that of the nearside mantle. This disparity points to a potential hemispheric dichotomy in the Moon’s internal water distribution, mirroring many of the asymmetrical features observed on the lunar surface.

The map to the right, figure 1 in the scientists’ paper, shows the water content from the samples that have so far been brought back from the Moon. Note how the Chang’e-6 sample shows far less water content than all the near side samples.

Note however also that this is just one data point from the far side. To confirm these conclusions will require many more samples.

Anti-Musk terrorists damage Musk statue in Brownsville

9:23 am

In another demonstration of their intolerance and willingness to commit violence and vandalism, anti-Musk terrorists have damaged a bust of Elon Musk in Brownsville that had been placed there by a French entrepreneur.

A 9-foot-tall statue depicting a bust of tech billionaire Elon Musk has been vandalized in South Texas. According to multiple posts across social media, the statue of the SpaceX CEO was vandalized not far from where the company’s Starbase facility sits near Boca Chica Beach.

“The recently installed Elon Musk statue, known as ‘Elonrwa,’ has been damaged. Visible patches of the outer layer appear to have been peeled off the face,” a Facebook user who goes by RGV.me said in an April 8 Facebook post. The Facebook post is accompanied by a photograph showing two areas where it appears a top layer of material has been stripped from the statue, revealing a white or pale gray layer underneath.

This senseless hate of Musk, almost certainly committed by supporters of the Democratic Party — which has been encouraging this violence because it sees Musk as an opponent — must end. And if the fools perpetrating this vandalism don’t come to their senses and stop voluntarily, they should be stopped by force and imprisonment. Just because you disagree with someone on policy does not give you the right to break the law.

And if you doubt this vandalism isn’t being spurred on eagerly by the leadership of the now vile and wholly evil Democratic Party, you need only watch that party’s Senate leader, Senator Charles Schumer (D-New York), practically endorse it when asked:

Juno enters and then recovers from safe mode

9:03 am

During its most recent close fly-by of Jupiter on April 4, 2025 — its 71st — the orbiter Juno went into safe mode two different times, causing its science instruments to shut down.

The mission operations team has reestablished high-rate data transmission with Juno, and the spacecraft is currently conducting flight software diagnostics.The team will work in the ensuing days to transmit the engineering and science data collected before and after the safe-mode events to Earth.

Juno first entered safe mode at 5:17 a.m. EDT, about an hour before its 71st close passage of Jupiter — called perijove. It went into safe mode again 45 minutes after perijove. During both safe-mode events, the spacecraft performed exactly as designed, rebooting its computer, turning off nonessential functions, and pointing its antenna toward Earth for communication.

Since arrival in its present Jupiter orbit in 2016 Juno has operated almost perfectly, having experienced only two other safe mode events, once in 2016 and a second in 2022. The two recent events on this most recent fly-by suggest however that the harsh environment surrounding Jupiter might be beginning to impact the spacecraft.

Isaacman’s nomination hearing reveals nothing of note

10:00 am

Jared Isaacman
Jared Isaacman

The Senate committee on commerce, science, and transportation has just concluded its hearing on the nomination of Jared Isaacman as NASA administrator. Several take-aways:

First, there was little opposition to Isaacman on either side of the aisle. He will be confirmed easily.

Second, Isaacman was very careful to say nothing that might commit him to keeping all present Artemis programs (such as SLS, Orion, or Gateway) unchanged. He instead made it clear his goal is for NASA to attempt a parallel programs to establish a permanent American presence on both the Moon and Mars. This enthusiasm suggests he sees Starship as the vehicle capable of making those parallel programs possible.

In other words, he kept his options open. His goal is to get the Artemis program functioning more efficiently, and will do whatever is necessary to do so. He repeatedly made it clear that too many of NASA’s projects, including specifically Artemis, are routinely overbudget and behind schedule, and this must be fixed.

At the same time he said his goal is to get Americans back to the Moon ahead of the Chinese, and suggested that the present plan using SLS and Orion is likely the fastest way to do so. The technical issues that might make that program very unsafe for the astronauts however were never mentioned.

We shall see whether Isaacman as administrator will be so sanguine about sending Americans around the Moon within an Orion capsule with a questionable heat shield.

Firefly wins Space Force contract to test orbital maneuvers with its Elytra space tug

12:33 pm

Firefly yesterday announced it has been awarded a Space Force contract to use its Elytra space tug to test orbital maneuvers designed for military purposes.

As part of the mission, Elytra will host a suite of government payloads, including optical visible and infrared cameras, a responsive navigation unit, and a universal electrical bus with a payload interface module. Firefly’s Elytra Dawn configuration will utilize common components from the company’s launch vehicles and lunar landers, including the avionics, composite structures, and propulsion systems, to enable on-demand mobility, plane changes, and maneuvers with high delta-V capabilities and reliability.

Though unstated, the inclusion of cameras suggests the Pentagon wants to test Elytra’s ability to maneuver close to other satellites and photograph them.

This contract further illustrates Firefly’s effort to diversify its space products. Like Rocket Lab, it is not relying solely on its rocket division to make money, but is also developing and selling a range of space products, from lunar landers to orbital tugs to satellite equipment.
