- Blue Origin touts its progress in reducing propellant boil-off while stored in tanks in space
This capability is essential for creating viable orbiting fuel depots.
- Astronomers claim to have detected a rogue exoplanet floating unattached to any star, using microlensing
Need I say it?
- A video overview of what we now know about Interstellar Comet 3I/Atlas
Not much new information, though it does describe briefly the unlikely (and very unrealistic) proposal of sending one of the Mars orbiters to rendezvous with it.
- Chinese pseudo-company AZSpace shows off its fully assembled Dear-5 cargo freighter
Its launch is now scheduled for August. It is not clear if it will dock with Tiangong-3, resupplying it, or is instead a free-flyer that will return to Earth for recovery.
India and China complete launches
Two more launches today. First, India’s space agency ISRO successfully placed a joint NASA-ISRO radar satellite into orbit, its GSLV rocket lifting off from its Sriharikota spaceport on the eastern coast of India.
This was India’s first fully successful launch in 2025. On the first launch in January, the GSLV rocket performed as planned, but the satellite’s own engines failed to put it into the right orbit. Then in May the third stage of its PSLV rocket failed during launch.
Next China placed the sixth group of nine satellites for one of its mega-constellations designed to compete with Starlink, its Long March 8A rocket lifting off from its Wenchang coastal spaceport.
The leaders in the 2025 launch race:
94 SpaceX
40 China
10 Rocket Lab
9 Russia
SpaceX still leads the rest of the world in successful launches, 94 to 70.
Curiosity looks back
Click for original image.
Cool image time! The picture to the right, reduced and enhanced to post here, was taken on July 28, 2025 by the left navigation camera on the Mars rover Curiosity. It looks to the north, down the flanks of Mount Sharp and across the floor of Gale Crater to its mountainous rim about 30 miles way, seen on the horizon.
The view is so clear because of the season, as noted in the science team’s blog post today:
We’re still in the time of year where the atmosphere at Gale is reasonably dust-free (at least, compared to later in the year), allowing us to look all the way out to and beyond the Gale crater rim. The upper slopes of Mount Sharp have also re-emerged to our east after spending months hidden behind the walls of Gediz Vallis. There’s a bit more sand and dust in this location than we’ve seen recently, so we can also see the trail left behind by the rover’s wheels as we drove to this location
The ridge in the foreground is an example of the boxwork Curiosity is presently traversing. It is now on one of those ridges, and will be moving along it in short drives as the science team studies the geology here. The rover’s tracks leading up to this position can be seen clearly.

A Webb false color image of a planetary nebula
Click for original image.
Cool image time! The picture to the right, reduced and sharpened to post here, was released today by the science team of the Webb Space Telescope, showing the planetary nebula NGC 6072 in infrared false color.
This particular image was one of two taken by Webb, and looked at the nebula in the near infrared.
[I]t’s readily apparent that this nebula is multi-polar. This means there are several different elliptical outflows jetting out either way from the center, one from 11 o’clock to 5 o’clock, another from 1 o’clock to 7 o’clock, and possibly a third from 12 o’clock to 6 o’clock. The outflows may compress material as they go, resulting in a disk seen perpendicular to it. Astronomers say this is evidence that there are likely at least two stars at the center of this scene. Specifically, a companion star is interacting with an aging star that had already begun to shed some of its outer layers of gas and dust.
The central region of the planetary nebula glows from the hot stellar core, seen as a light blue hue in near-infrared light. The dark orange material, which is made up of gas and dust, follows pockets or open areas that appear dark blue. This clumpiness could be created when dense molecular clouds formed while being shielded from hot radiation from the central star. There could also be a time element at play. Over thousands of years, inner fast winds could be ploughing through the halo cast off from the main star when it first started to lose mass.
The second image, taken in the mid-infrared, shows expanding dust shells, with some forming an encircling ring around the central nebula.
It is believed that the two stars at the center of this nebula act to churn the expanding material to form this complex shape. Imagine them functioning almost like the blades in a blender.
Next Starship moves to launchpad for static fire testing
SpaceX has now finished work adapting the Boca Chica launchpad for Starship and has installed the next Starship prototype there for static fire testing prior to the tenth orbital test flight expected in the next few weeks.
The pad is normally configured for Superheavy. SpaceX engineers have quickly jury-rigged it to fit Starship to it for static fire tests because the normal Massey test stand was badly damaged in an explosion during static fire tests of the previous prototype in June.
With this setup, SpaceX is going to be able to static fire a ship on Pad 1 (A). SpaceX will likely do some quick pressure and leak checks; however, no tanking tests appear to be planned. SpaceX seems confident enough in this setup that crews are aiming for a static fire on Wednesday, July 30, and a second static fire on Thursday, July 31. Both of these days have testing closures set for 7 am – 7 pm CDT.
If these go as planned and there are no issues, which, considering how makeshift this setup is, would be a massive achievement. Once its engine testing is completed, SpaceX will roll Ship 37 back to Mega Bay 2 for final work and return the pad to launch configuration; this process could take approximately two weeks.
The company will then do its standard static fire tests of Superheavy, stack Starship on top, and be ready for launch, hopefully by mid- to late August.
This Starship is one of the last two version-2 Starships being prepped for test flights. After they have flown, the company will move to version-3, which hopefully will have a better flight success record than version-2.
Thales Alenia ships the orbit insertion module for the Mars sample return mission
Though the entire project remains in limbo at NASA and might be cancelled, the European aerospace company Thales Alenia this week completed construction of the orbit insertion module for the Mars sample return mission that will place the orbiter — also built by European companies — in Mars orbit and will eventually bring the samples back to Earth.
On 28 July, Thales Alenia Space announced that the module had passed its test campaign with “excellent results.” According to the update, the company had packed and shipped the Orbit Insertion Module from its Turin facilities to Airbus in Stevenage a few days earlier. The delivery marks a key milestone in the development of the Mars Return Orbiter.
The broader Earth Return Orbiter project passed a key milestone in July 2024 with the completion of the Platform Critical Design Review. This review confirmed the performance, quality, and reliability of the mission’s systems. With its successful conclusion, Airbus advanced to full spacecraft development, including the integration and testing of its various components, among them the Orbit Insertion Module.
Under the project’s present very complex design, NASA is supposed to provide the ascent rocket and capsule to bring the samples to Europe’s return orbiter. At the moment it is unclear who will build this, or even if it will ever get built. Thus, Europe might be building a very expensive Mars orbiter with no clear mission.
Firefly wins new NASA lunar lander contract, worth $176.7 million
NASA announced yesterday that it has awarded Firefly a $176.7 million contract to use the company’s Blue Ghost lunar lander to deliver two rovers and three other science instruments to the Moon’s south pole region.
Under the new CLPS task order, Firefly is tasked with delivering end-to-end payload services to the lunar surface, with a period of performance from Tuesday to March 29, 2030. The company’s lunar lander is targeted to land at the Moon’s South Pole region in 2029.
This is Firefly’s fifth task order award and fourth lunar mission through CLPS. Firefly’s first delivery successfully landed on the Moon’s near side in March 2025 with 10 NASA payloads. The company’s second mission, targeting a launch in 2026, includes a lunar orbit drop-off of a satellite combined with a delivery to the lunar surface on the far side. Firefly’s third lunar mission will target landing in the Gruithuisen Domes on the near side of the Moon in 2028, delivering six experiments to study that enigmatic lunar volcanic terrain.
One of the rovers is being built in partnership with Canada.
SpaceX launches 28 more Starlink satellites
SpaceX this evening successfully placed 28 more Starlink satellites in orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.
The first stage completed its 26th flight, landing on a drone ship in the Atlantic.
The leaders in the 2025 launch race:
94 SpaceX
39 China
10 Rocket Lab
9 Russia
SpaceX now leads the rest of the world in successful launches, 94 to 68.

Gilmour’s first launch a failure
Click for video, cued to just before launch.
The first launch of the Australian rocket startup Gilmour Space’s Eris rocket ended in failure today when the rocket started drifting sideways after rising about 150 feet and then crashing near the launchpad.
The picture to the right is a screen capture from an independent live steam of the launch posted on youtube by Aussienaut, captured about 20 seconds after liftoff. The red dot indicates the location of the launchpad where the rocket took off to make clear the rocket’s sideways motion. Ten seconds after this, the rocket fell to the ground and exploded.
This launch attempt was the first ever by a private commercial Australian rocket company, so the failure itself is not surprising. It was also the first orbital test launch from a privately owned Australian spaceport. Whether the company has the resources to recover remains to be seen, but I suspect it will try again.
Starlab partners with the interior design company Journey

The consortium designing the commercial Starlab space station has now signed a partnership deal with the interior design company Journey for the latter to design the station’s habitable interior.
Journey brings a deep portfolio of globally recognized projects, including the Sphere in Las Vegas, the Empire State Building observatory in New York City and the Sun Princess Dome for Princess Cruises. The agency will be working closely with Hilton, one of the original strategic partners in the Starlab program, designing the Starlab hospitality and crew experience. Journey’s role adds a vital layer of design and experiential innovation, shaping a space that reflects both function and humanity.
Much of the press release is similar blather. It is good that Starlab is thinking about making the living space in its station “both a cutting-edge research platform and a welcoming, livable habitat,” but this deal doesn’t include any actual design work. Apparently nothing concrete will be done until Starlab wins the big NASA construction project — assuming it does so. Thus, I still rank Starlab low in my rankings of the four commercials stations being built or proposed, but this deal has convinced me to raise its ranking above Orbital Reef. Both have built little, but Starlab is at least making a lot of partnership deals with others, strengthening the quality of its team.
- 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 an estimated 30 days total. 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 four tourist flights to ISS, with the fourth carrying government 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.
- Starlab, being built by a consortium led by Voyager Space, Airbus, and Northrop Grumman, with an extensive partnership agreements with the European Space Agency and others. It recently had its station design approved by NASA, but it has built nothing. The company however has now raised $383 million in a public stock offering, which in addition to the $217.5 million provided by NASA gives it the capital to begin some construction.
- Orbital Reef, being built by a consortium led by Blue Origin and Sierra Space. Overall, Blue Origin has built almost nothing, while Sierra Space has successfully tested its inflatable modules, including a full scale version, and appears ready to start building its module for launch.
