China releases images of Earth and Moon, taken by its Tianwen-2 asteroid probe

9:40 am

Tianwen-2 images of the Earth and the Moon
For original images go here and here.

According to a report today in China’s state-run press, its Tianwen-2 asteroid sample return spacecraft is operating normally, and has successfully taken pictures of both the Earth and the Moon to test its instrumentation.

Those images are to the right, cropped, reduced, and sharpened to post here.

The CNSA [China National Space Administration] said that the narrow-field-of-view navigation sensor equipped on the probe recently captured the images of Earth and the moon, demonstrating good functional performance.

The images released include a photograph of Earth obtained by Tianwen-2 when it was approximately 590,000 kilometers away from the planet, as well as a new photograph of the moon captured when it was about the same distance from the moon. After the images were transmitted back to the ground, they were processed and produced by scientific researchers.

The Tianwen-2 probe has currently been in orbit for over 33 days, at a distance from Earth exceeding 12 million kilometers, and it is in good working condition, the CNSA said.

The probe will take about a year to reach asteroid Kamo’oalewa, where it will fly in formation studying it for another year, during which time it will attempt to grab samples by two methods. One method is a copy of the touch-and-go technique used by OSIRIS-REx on Bennu. The second method, dubbed “anchor and attach,” is untried, and involves using four robot arms, each with their own drill.

Speculation on future New Glenn launch schedule

9:26 am

According to anonymous sources at Blue Origin, the company has now delayed the second launch of its New Glenn rocket to September, ten months after its first launch in January 2025, and hopes to quickly follow with three more launches by the middle of 2026.

The September launch will launch NASA’s two smallsat Escapade Mars orbiters.

After Escapade, Blue Origin has several missions tentatively plotted out. However, sources cautioned that the manifest could be moved around due to the readiness of subsequent New Glenn vehicles and their payloads. Based upon information received by Ars, the launch manifest could look something like this:

  • New Glenn 2: ESCAPADE (fall 2025)
  • New Glenn 3: Firefly’s Elytra orbital transfer vehicle (end of 2025, early 2026)
  • New Glenn 4: Blue Moon MK1 lander (first half of 2026)
  • New Glenn 5: First batch of 49 Amazon Project Kuiper satellites (mid-2026)

Whether this schedule will occur as speculated is unknown. Blue Origin’s long term track record — slow and timid — suggests it is very unlikely. And even if it does fly as planned, it suggests strongly that Amazon is not going to meet its FCC license requirement to have 1,600 Kuiper satellites in orbit by July 2026. So far Amazon has only placed 54 operational Kuiper satellites into orbit, on two Atlas-5 launches. It has contracts to launch these satellites 46 times on ULA rockets (8 on Atlas-5 and 36 on Vulcan), 27 times on Blue Origin’s New Glenn, 18 times on ArianeGroup’s Ariane-6, and 3 times on SpaceX’s Falcon-9.

Except for the Falcon 9, none of the other rockets have begun flying with any frequency. Vulcan has only launched twice, New Glenn once, and Ariane-6 twice. All three have been extremely slow to ramp up operations, with months passing between each launch. To meet Amazon’s FCC license requirements, they will have to achieve between 35 to 60 launches in the next twelve months, a pace of three to six launches per month. At this point none of these companies appear capable of even coming close to doing this.

Nor does Amazon have the option to switch these launches to the Falcon 9. SpaceX would certainly accept the business, but the manifest for the Falcon 9 is presently very full. It is doubtful it could do more than double or triple its commitment to Amazon.

NASA still hoping to save its Lunar Trailblazer mission

8:59 am

Though the odds of success are very dim, NASA has decided to give engineers another few weeks to try to activate its Lunar Trailblazer orbiter, that stopped communicating with Earth the day after it was launched in late February.

NASA has extended recovery efforts of its Lunar Trailblazer spacecraft from mid-June to early July. Updated modeling of the spacecraft’s trajectory by the mission team indicates lighting conditions will continue to be favorable and may provide enough sunlight for the spacecraft’s solar panels to recharge its batteries to an operational state and turn on its radio.

…Should enough sunlight reach Lunar Trailblazer’s solar panels, the batteries may charge to a level that allows the spacecraft’s radio system to boot up. But as Lunar Trailblazer travels farther away, it will soon be too distant to recover because its telecommunications signals to Earth will be too weak for the mission to receive telemetry and command.

The mission team has determined that if they can regain command of the spacecraft, the propulsion system isn’t frozen, and the instruments remain operable, the spacecraft may be able to achieve an elliptical lunar orbit and complete its lunar science objectives.

As I said, the chance of success are not good.

Mitsubishi wants to cut launch price of H3 rocket to $35 million

8:52 am

Mitsubishi Heavy Industries, which developed the new H3 rocket for Japan’s space agency JAXA, wants to attract commercial launch business, and to do so hopes to cut the rocket’s launch price to about $35 million.

According to the article at the link, the price for the H2A rocket that the H3 has replaced was 10 billion Japanese yen, about $70 million.

The H2A launched more than 70 satellites and other objects into space, serving as the backbone of Japan’s space transportation. However, there was an average of only two launches a year, and most depended on “public demand” for government satellites. There were only orders for commercial launches for five satellites belonging to foreign countries, such as South Korea and the United Kingdom.

…For Mitsubishi Heavy Industries, Ltd., which took over the manufacture and operation of the H2A from JAXA in 2007, winning commercial orders has been a longstanding issue. The H3 was jointly developed by MHI and JAXA with the aim of halving the launch fee.

That price listed for the H2A rocket is likely wrong, much lower than the real price, as it matches what SpaceX has been offering publicly for the Falcon 9 for more than a decade. If the H2A had been that cheap, it would have garnered some business. It did not.

Lowering the cost for the H3 rocket to $35 million would definitely be competitive in the present launch market. Whether Mitsubishi can accomplish this however remains unclear. So far there is no indication that this new rocket has attracted any more business than the H2A, but as the rocket has only just started launching it is still too early to judge.

Baby stars illuminating the dust that surrounds them

Baby stars illuminating dark dust
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope showing the wispy bluish clouds made of dark dust that we can only see because the dust is illuminated by the reflected light from the five red and blue stars nearby. Think of the Moon, lit only by the reflected light of the Sun.

The photo however was not taken to study the clouds, but these baby stars, located in one of the closest star forming regions of the Milky Way.

GN 04.32.8 is a small part of the stellar nursery known as the Taurus Molecular Cloud. At only roughly 480 light-years from Earth in the constellation Taurus, it’s one of the best locations for studying newly forming stars. This reflection nebula is illuminated by the system of three bright stars in the centre of this image, mainly the variable star V1025 Tauri in the very centre. One of those stars overlaps with part of the nebula: this is another variable star that is named HP Tauri, but is classified as a T Tauri star, for its similarity to yet another variable star elsewhere in the Taurus Molecular Complex. T Tauri stars are very active, chaotic stars at an early stage of their evolution, so it’s no surprise that they appear in a prolific stellar nursery like this one! The three stars are also named HP Tau, HP Tau G2 and HP Tau G3; they’re believed to be gravitationally bound to each other, forming a triple system.

Eagle-eyed viewers might notice the small, squashed, orange spot, just left of centre below the clouds of the nebula, that’s crossed by a dark line. This is a newly-formed protostar, hidden in a protoplanetary disc that obstructs some of its light. Because the disc is edge-on to us, it’s an ideal candidate for study. Astronomers are using Hubble here to examine it closely, seeking to learn about the kinds of exoplanets that might be formed in discs like it.

As beautiful as this image is, it is that tiny protostar near the bottom that likely attracts the most interest from astronomers.

Update on SpaceX’s plans to resume Starship/Superheavy flight testing

9:37 am

Link here. The article provides a detailed overview of the situation at Boca Chica following the static fire explosion of a Starship on June 18, 2025, which badly damaged the Masseys test stand used by Starship prior to launches.

The problem facing the company is that it wants to fly the last few version-two Starships (called Block 2) before it is ready to switch to the upgraded Block 3, and these two versions apparently require a different set up on the test stand. The article outlines three options, with the first two the simplest and most straightforward, but require the most delays.

Option three, which is the most SpaceX-like of them all, would involve the repair Masseys for Block 3 and, in parallel, attempt to come up with a plan to static fire Ships on Orbital Launch Pad 1 (A). This would allow SpaceX to continue testing and flying the remaining Block 2 Ships while preparing for Block 3 of Starship. This is what SpaceX is planning.

In other words, do Block 2 Starship prelaunch static fire tests on the launchpad itself while Masseys is being rebuilt for Block 3.

The article outlines in detail the technical difficulties this plan requires, because the launch mount is also used for prelaunch static fire tests of Superheavy. The two rockets require different mount clamping and fueling systems.

If this is the plan that SpaceX is following, it will likely mean that the next test flight, the tenth, will occur in about two months, maybe sooner. We will get a better idea of the company’s plans in the coming weeks.

Blue Origin completes another New Shepard suborbital flight

9:20 am

My heart be still. Blue Origin yesterday successfully flew another New Shepard suborbital tourist flight, sending six passengers on a ten minute flight to the edge of space.

This was the company’s thirteenth suborbital flight, and the third in the past three months. Though it is gratifying that operations of New Shepard are becoming somewhat routine, it would be much more exciting if the company to do the same for its New Glenn orbital rocket. The suborbital flights are essentially a dead end. The real money and future is found in orbital operations, something Blue Origin has still not yet mastered.

Orbex delays first launch from Saxavord until 2026

2:26 pm

Map of spaceports surrounding Norwegian Sea
Proposed spaceports surrounding the Norwegian Sea

The rocket startup Orbex has now announced that “infrastructure requirements and engagement with regulators” has forced it to delay the first launch of its Prime rocket from 2025 until 2026.

Orbex at the start of this decade had signed a 50-year lease to launch its Prime rocket from the proposed Sutherland spaceport on the north coast of Scotland. In February 2022 it applied for a launch license, with the hope of launching before the end of that year. For three years it waited for the UK’s Civil Aviation Authority (CAA) to approve that license, to no avail.

Finally in December 2024 it gave up on launching from Sutherland and shifted its plans to the Saxavord spaceport in the Shetland Islands, apparently because that spaceport had been more successful in getting its CAA approvals (though even it had to wait years).

Though the company attributes this new delay as much to getting its launch facility ready at Saxavord, delays caused by British red tape continues to be a systemic and entrenched problem in the United Kingdom. It appears it remains so.

More successful launches today

10:44 am

Two more launches occurred this morning, one in Japan and one in the U.S.

First, Japan completed the last launch of its H2A rocket, lifting off from its Tanegashima spaceport in south Japan, placing a Japanese climate satellite into orbit. This was the 50th launch for the H2A, which has now been replaced by the as expensive H3 rocket.

Next, SpaceX continued its unrelenting launch pace, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California carrying 26 more Starlink satellites into orbit. The first stage completed its eighth flight, landing on a drone ship in the Pacific Ocean.

As Japan’s launch was only its second in 2025, it does not make the leader board of the 2025 launch race:

82 SpaceX
35 China
10 Rocket Lab
7 Russia

SpaceX still leads the rest of the world in successful launches, 82 to 61.

Two American launches this evening

12:19 am

This evening two different American companies completed successful commercial launches, doing so from opposites sides of the globe.

First, SpaceX launched another 27 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral, with the first stage completing its fifth flight, landing on a drone ship in the Atlantic Ocean. This launch was on the evening of June 27th.

Then, a few hours later Rocket Lab completed the first of two quickly scheduled launches for an unnamed commercial customer, its Electron rocket lifting off from one of its two launchpads in New Zealand. This launch, on June 28th in New Zealand, was the company’s second launch in less than two days, its fastest turn around yet. As of posting the payload was not yet deployed.

The leaders in the 2025 launch race:

81 SpaceX
35 China
10 Rocket Lab
7 Russia

SpaceX still leads the rest of the world in successful launches, 81 to 60.

OSHA investigating the collapse of a crane at SpaceX’s Boca Chica facility

9:13 am

OSHA has now opened an investigation into the collapse of a crane at SpaceX’s Boca Chica facility on June 24, 2025, captured by one of the commercial live streams that track activities there continually for the general public.

I have embedded the video of that collapse below.

A SpaceX crane collapse at the company’s Starbase, Texas facility on Tuesday has prompted an investigation by the Occupational Safety and Health Administration, the federal agency told CNBC in an email.

The crane collapse was captured in a livestream by Lab Padre on YouTube, a SpaceX-focused channel. Clips from Lab Padre were widely shared on social media, including on X, which is owned by SpaceX CEO Elon Musk.

It wasn’t immediately clear whether any SpaceX workers were injured as a result of the incident. Musk and other company executives didn’t respond to a request for comment.

The article at the link provides no additional information, instead focusing on what appears to be an anti-SpaceX screed. It never mentions that cranes such as this are almost certainly not owned by SpaceX, and are likely rented and operated for SpaceX by other independent crane companies. Thus, this failure is likely a failure of that crane company, not SpaceX directly.

The sagging flank of one of Mars’ giant volcanoes

The sagging flank of Elysium Mons
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on May 1, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the science team labels a “chain of pit craters in [a] graben”.

A graben is a surface fissure created when the surface either spreads or two sections shift sideways in opposite directions. The chain of pits suggest that there is a larger void below into which the surface is sinking. It is also likely that a lot of the sinking material is volcanic ash, thrown free in an eruption hundreds of millions of years ago, which over the eons has been blown up to this location to settle in the crack to fill it. It is now trapped there, and sinking.

What caused the ground here to shift and create the fissure? In this case, the cause is quite large and massive, in a way that boggles the mind.

Nozzle blows off of Northrop Grumman SLS solid rocket booster during static fire test

1:05 pm

During a static fire test of a new upgraded strap-on solid-fueled booster to be used on the second version of NASA’s SLS rocket, it appears the nozzle broke off near the end of the test.

I have embedded the video below.

This failure is not good for getting the upgraded version of SLS built, dubbed Block 2. Block 1 has flown once unmanned, and is planned for the next two manned missions. Block 2 would be for further manned missions beyond that. The Trump administration has proposed cancelling it, ending SLS after those two Block 1 flights. Senator Ted Cruz (R-Texas) has instead introduced a bill that would save it in order to fly two Block 2 SLS manned missions.

This failure is definitely going to delay and add cost to Block 2 development, a program that is already over budget many times over and a decade-plus behind schedule. These additional delays and cost overruns are not going to help it politically. It justifies the Trump administration’s desire to cancel it.

Moreover, this nozzle failure suggests a very fundamental design problem. Northrop Grumman, which built and was testing this booster, also builds the solid-fueled strap-on boosters used on ULA’s Vulcan rocket, which had a similar nozzle failure during Vulcan’s second launch in October last year. Both Northrop Grumman and ULA have said they had identified and fixed the cause of that failure, and the military has certified it for operational launches, but nonetheless Vulcan still remains sidelined, more than eight months later.

I suspect ULA is going to have to do more testing of the Northrop Grumman Vulcan side boosters before its next Vulcan launch, delaying that rocket further.

French startup Latitude to spend $9.3 million on building its French Guiana launch facility

Ariane-6 pad.)

The French rocket startup Latitude has announced it will spend $9.3 million to build its own launchpad at the spaceport in French Guiana, where hopes to launch its Zephyr rocket in 2026.

In a 23 June update, Latitude confirmed the Guiana Space Centre as the launch site for the inaugural flight of its 19-metre-tall, two-stage Zephyr rocket, which is designed to deliver payloads of up to 200 kilograms to low Earth orbit. The site was one of two under consideration, with the company also having committed to developing launch infrastructure at SaxaVord Spaceport in Scotland. When that partnership was announced in March 2022, Latitude, then known as Venture Orbital Systems, aimed to carry out its first launch from SaxaVord in 2024.

Construction of the ELM-Diamant shared launch facility began in 2025 and is expected to be completed by 2026. According to Latitude’s 23 June update, the company will work with CNES and the European Space Agency in the coming months to implement its dedicated launch infrastructure at the site. This will be followed by the inaugural launch of its Zephyr rocket in 2026.

It is not clear exactly how that ELM-Diamant launch site will be shared. France’s space agency CNES (which operates French Guiana) had previously said it wanted all the new European rocket startups that wanted to launch from there to use a common launch infrastructure, thus requiring them to share technology as well as redesign their rockets to fit CNES’s requirements. The rocket startups objected, but it now appears two startups, Latitude and PLD, and come to an agreement of some sort.

This deal also suggests that Latitude is shifting away from using the Saxavord spaceport in the United Kingdom, possibly because it has seen the difficult regulatory hurdles required there and has decided French Guiana is a better option.

Webb takes infrared image of exoplanet

9:32 am

Webb's image of exoplanet

Using the Webb Space Telescope astronomers have now successfully taken an infrared false-color image of Saturn-sized exoplanet orbiting a young star about half the mass of the Sun and about 111 light years away.

The image is to the right, cropped and reduced to post here. The star, its light blocked out, is indicated by the circle with the star in the middle. The exoplanet is the orange blob to the upper right, sitting inside the blue accretion disk that surrounds the star, photographed in optical light by the Very Large Telescope in Chile.

You can read the paper here. The scientists rejected the possibility that this was a background galaxy after doing computer modeling, based on the data available. From their paper:

Dedicated N-body simulations were conducted for a planet with a mass of 0.34 [mass of Jupiter], located at 52 au [astronomical units] around the 0.46 [solar mass] central star. This value is consistent with the measured projected separation, assuming that the planet and the ≈13°-inclined disk are coplanar. The simulation also included a disk of 200,000 planetesimals, distributed between 20 and 130 au. These parameters were selected to roughly match the boundaries of the observed disk.

Note too that the picture to the right has been significantly enhanced by the press department at JPL, based on the actual data shown in the paper itself. These fact underline the uncertainties involved in this discovery.

Nonetheless, it is a good result, and suggests we are looking at the formation process of a new solar system surrounding a very young baby star.

Mexican president threatens action against SpaceX at Boca Chica

9:08 am

The president of Mexico, Claudia Sheinbaum, yesterday indicated that her government was considering taking legal action against SpaceX because of the debris from its Superheavy rocket that was found washed up on its beaches after a test launch.

Mexico’s government was studying which international laws were being violated in order to file “the necessary lawsuits” because “there is indeed contamination”, Sheinbaum told her morning news conference on Wednesday.

…Mexican officials are carrying out a “comprehensive review” of the environmental impacts of the rocket launches for the neighboring state of Tamaulipas, Sheinbaum said.

Other than this one quote, the article at the link is largely junk, focusing on the test stand explosion last week of Starship, an event that has nothing to do with the material found on Mexico’s beaches. Moreover, that debris was apparently so harmless Mexicans were able to quickly gather it for souvenirs, with some immediately making money from it by selling it on social media.

In other words, this “investigation” and this “reporting” is nothing more than anti-Musk rhetoric because Musk has aligned himself with Trump.

Axiom’s manned mission docks with ISS

8:56 am

SpaceX’s newest manned Dragon capsule, dubbed Grace, this morning successfully brought Axiom’s fourth commercial passenger mission to ISS, docking with the space station after launching yesterday on a Falcon 9 rocket.

The spacecraft docked at 6:31 a.m. to the space-facing port of the space station’s Harmony module. Former NASA astronaut Peggy Whitson, ISRO (Indian Space Research Organisation) astronaut Shubhanshu Shukla, ESA (European Space Agency) astronaut Sławosz Uznański-Wiśniewski of Poland, and Tibor Kapu of Hungary now are aboard the space station after launching at 2:31 a.m. on June 25, on the company’s Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida for the fourth private astronaut mission to the orbiting laboratory, Axiom Mission 4.

The plan is for them to stay on ISS for two weeks.

Astronomers look at the Andromeda Galaxy in many wavelengths

3:11 pm

Andromeda across many wavelengths
Click for full images.

Astronomers using both old and new and ground- and space-based telescopes have created a full set of observations of the Andromeda Galaxy (also known as M31) across five different wavelengths, producing one of the most complete views of the galaxy so far.

This new composite image contains data of M31 taken by some of the world’s most powerful telescopes in different kinds of light. This image includes X-rays from NASA’s Chandra X-ray Observatory and ESA’s (European Space Agency’s) XMM-Newton (represented in red, green, and blue); ultraviolet data from NASA’s retired GALEX (blue); optical data from astrophotographers using ground based telescopes (Jakob Sahner and Tarun Kottary); infrared data from NASA’s retired Spitzer Space Telescope, the Infrared Astronomy Satellite, COBE, Planck, and Herschel (red, orange, and purple); and radio data from the Westerbork Synthesis Radio Telescope (red-orange).

Each type of light reveals new information about this close galactic relative to the Milky Way. For example, Chandra’s X-rays reveal the high-energy radiation around the supermassive black hole at the center of M31 as well as many other smaller compact and dense objects strewn across the galaxy.

The contrast in emissions between different wavelengths is certainly striking. The radio, infrared, and ultraviolet data clearly delineate the galaxy’s arms where star formation is occurring. The X-ray highlights the galaxy’s central black hole.

This press release is clearly intended to lobby against the cuts at NASA, especially considering that several of these images (Galax, Spitzer) are not new. At the same time, it does demonstrate the need to look at the heavens across the entire electromagnetic spectrum. It seems to me that the astronomical community should begin to consider other methods of funding for this work, other than just the federal government, and in fact they prove this point themselves by the use of images above from some smaller ground-based telescopes not funded by American tax dollars.

Cool image time! The panorama above, assembled from two pictures taken on June 23, 2025 (here and here) by the left navigation camera on the Mars rover Curiosity, looks to the south and uphill into the canyon that the rover will eventually climb.

The overview map to the right provides context. The blue dot marks Curiosity’s present location, the white line its past travel route, and the red dotted line its future route. The yellow lines indicate the approximate area covered by the panorama.

The science team is presently exploring the boxwork formation on the right, and should spend at least the next month or so there before moving on. As the rover moves up into this canyon we should also expect the science team to spend a great deal of time studying that many layered cliff face to the right.

Eventually the rover will enter those white very hilly regions on the horizon. No route through those hills however has yet been chosen.

German rocket startup Isar Aerospace secures $174 million in financing

9:23 am

The German rocket startup Isar Aerospace announced today that it has obtained $174 million in new financing from a Miami-based investment firm.

This news report adds these details:

On 25 July 2025, Isar Aerospace announced that it had signed a €150 million convertible-bond agreement with Eldridge Industries. The instrument provides the company with funding in the short term, and the debt can later be converted into equity in the form of shares, typically at a pre-agreed valuation during a future financing round or an IPO.

That Isar needed to go to an American investment firm suggests there was a lack of interest in Europe to invest in this European rocket startup. The nature of the deal also suggests the possibility that some ownership rights will shift to Eldridge over time.

In March Isar first launch attempt of its Spectrum rocket from Norway’s Andoya spaceport failed 30 seconds after lift-off. It is building two more rockets, and will use this new capital to expand its production and launch facilities.

Rocket Lab wins launch contract from the European Space Agency

9:09 am

The American rocket company Rocket Lab announced today that it has been awarded a launch contract from the European Space Agency (ESA) to place two European-built GPS-type test satellites into orbit.

Rocket Lab will launch two “Pathfinder A” spacecraft for ESA, provided by European satellite prime contractors Thales Alenia Space and GMV, from Rocket Lab Launch Complex 1 no earlier than December 2025. The spacecraft will be deployed to a 510km low Earth orbit as part of a mission to test a new approach of providing location, direction, and timing services from satellites in low orbit – otherwise called LEO-PNT (Low Earth Orbit Positioning, Navigation, and Timing). ESA’s LEO-PNT demonstration mission will assess how a low Earth orbit fleet of satellites can work in combination with the Galileo and EGNOS constellations in higher orbits that provide Europe’s own global navigation system.

That ESA gave Rocket Lab this contract illustrates the failure of this government agency’s own commercial rocket division, Arianespace, as well as the slowly emerging new commercial rocket startups in Europe. ESA likely rejected Arianespace’s Ariane-6 and Vega-C rockets as too expensive. These rockets were also likely unable to meet the required launch time table. It also could not pick any independent private European companies, because none have yet to successfully launch.

And ESA did this even as top government officials in Europe have been loudly demanding that Europe only launch its satellites on European rockets. That demand might make a nice sound bite, but reality trumps nice sound bites every time.

SpaceX launches Axiom’s fourth commercial manned mission to ISS

8:45 am

SpaceX last night successfully launched Axiom’s fourth commercial manned mission to ISS, dubbed Ax-4, its Falcon 9 rocket lifting off from the Kennedy Space Center in Florida.

The first stage completed its second flight, landing back at Cape Canaveral. The Dragon capsule, the newest and fifth ship in SpaceX’s fleet of manned capsule, was dubbed “Grace,” as announced by Axiom mission commander and former NASA astronaut Peggy Whitson. The three paying passengers are government astronauts from India, Hungary, and Poland.

The capsule will dock with ISS tomorrow (Thursday) at 7 am (Eastern), where it and its crew will spend about one to two weeks before returning to Earth.

The leaders in the 2025 launch race:

79 SpaceX
35 China
8 Rocket Lab
7 Russia

SpaceX now leads the rest of the world in successful launches, 79 to 58.

The overall lack of excitement about this manned space mission speaks directly to how successful SpaceX has become as a private commercial rocket company. Its rockets and capsules work routinely well, with almost no problems, making these manned space missions seem as boring as an airline trip from New York to Washington.

A graceful spiral galaxy

A graceful spiral galaxy
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope as part of a project to study galaxies with very active central supermassive black holes.

What sets UGC 11397 apart from a typical spiral lies at its centre, where a supermassive black hole containing 174 million times the mass of the Sun is growing. As a black hole ensnares gas, dust, and even entire stars from its vicinity, this doomed matter heats up and puts on a fantastic cosmic light show. Material trapped by the black hole emits light from gamma rays to radio waves and can brighten and fade without warning. But in some galaxies, including UGC 11397, thick clouds of dust hide much of this energetic activity from view in optical light. Despite this, UGC 11397’s actively growing black hole was revealed through its bright X-ray emission — high-energy light that can pierce the surrounding dust. This led astronomers to classify it as a Type 2 Seyfert galaxy, a category used for active galaxies whose central regions are hidden from view in visible light by a doughnut-shaped cloud of dust and gas.

To me what sets this galaxy apart is its natural beauty. It also reminds me of the universe’s vastness. Located about 250 million light years away, those hazy spiral arms represent millions of stars, many of which likely harbor planets and maybe even life.

Another permanently shadowed crater on the Moon shows no obvious ice

11:40 am

The permanently shadowed floor of Hermes-A crater, as seen by Shadowcam
Note that the bright areas are not ice but simply overexposed

The science team operating the Shadowcam camera on South Korea’s Danuri lunar orbiter — designed to take images in places with little light — yesterday released a new image taken of the floor of a permanently shadowed crater on the Moon, Hermes-A, located near the north pole.

That picture is to the right. The rectangle indicates the area discussed by the release, focusing entirely on describing its geological features, such as impact melt and the numerous secondary smaller impacts and ejecta within the crater floor. The inset gives the context, showing the crater’s location near the north pole. The blue areas in the inset are those areas thought to be permanently shadowed, such as the entire floor of Hermes-A.

What the release fails to mention is the most important detail lacking in this picture. Though the floor of Hermes-A crater is considered permanently shadowed, the low light image taken by Shadowcam shows no obvious ice features, at all. If there is a higher content of water here, it is locked within the soil, and would require processing to access. Even so, the picture suggests that any such moisture is of extremely low concentration, likely in the parts per billion, and hardly enough to build a lunar base.

This is the same result found by previous Shadowcam pictures. Increasingly it appears that the hope of finding large quantities of easily accessible water ice in these permanently shadowed craters is proving false.

NASA sets another new date for Axiom’s Ax-4 commercial manned mission to ISS

9:21 am

NASA today announced a new launch date of June 25, 2025 for Axiom’s Ax-4 commercial manned mission to ISS carrying a three passengers from India, Poland, and Hungary respectively and commanded by former NASA astronaut Peggy Whitson (now working for Axiom).

As with previous announcements, the information provided was sparse:

NASA, Axiom Space, and SpaceX are targeting 2:31 a.m. EDT, Wednesday, June 25, for launch of the fourth private astronaut mission to the International Space Station, Axiom Mission 4.

The mission will lift off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The crew will travel to the orbiting laboratory on a new SpaceX Dragon spacecraft after launching on the company’s Falcon 9 rocket. The targeted docking time is approximately 7 a.m. Thursday, June 26. NASA will provide more details and its coverage information shortly.

The launch had previously been delayed several times because NASA and Russia wanted to first assess the repair work on the leaks in the Russian Zvezda module before allowing another docking at the station. No information however has been released so far detailing that assessment. Though there have been indications that the loss of air in ISS was stopped by the repair, neither NASA nor Roscosmos have provided any specific data.

2nd test flight of French cargo capsule prototype “partial success”

9:13 am

According to an update today from the French cargo capsule startup The Exploration Company, its Mission Possible capsule prototype launched yesterday on SpaceX’s Falcon 9 had a “partial success (partial failure)” during its return to Earth.

The capsule was launched successfully, powered the payloads nominally in-orbit, stabilized itself after separation with the launcher, re-entered and re-established communication after black out. But it encountered an issue afterwards, based on our current best knowledge, and we lost communication a few minutes before splash down. We are still investigating the root causes and will share more information soon.

This was the second prototype test flown by the company, the first launched on the inaugural flight of the Ariane-6 rocket. That test was unable to complete its mission because of a problem with the rocket’s upper stage, which prevented it from completing its de-orbit burn, which would have then permitted the prototype to be released and return to Earth for flight testing. Instead, no test was done.

The company had initially only planned two test flights of these smaller prototypes before moving on to test flights of its full scale Nyx cargo capsule, designed to garner commercial cargo business to and from the space stations presently under development. The update today suggests it might now do another test flight with a smaller prototype.

Ispace: Resilience’s failure was due to a hardware issue in laser range finder

8:34 pm

In a press conference today, officials of the Japanese startup Ispace explained that the failure of its second lunar lander, Resilience, to land softly on the Moon on June 5, 2025 was due to a hardware issue in its laser range finder that prevented it from providing correct altitude data.

At the same time, they have not yet been able to pin down precisely what caused the failure. It could have been because of unexpected degradation during flight, or possibly a technical fault with the range finder in gathering data at the speeds and altitudes experienced.

The company is forming a task force in partnership with Japan’s space agency JAXA as well as NASA to try to figure out the issue. It is also going to add lidar instrumentation to future missions to provide a backup to the laser range finder. These actions will add about $11 million in additional costs, an amount Ispace says it can absorb.

Ispace is building two more lunar landers, one for NASA in partnership with the American company Draper, and the second for JAXA. It appears both missions are still moving forward.

SpaceX completes another smallsat Transporter launch, launching 70 payloads

3:23 pm

SpaceX today successfully placed 70 payloads, including 66 separate deployments, into orbit as part of its Transporter program for smallsats, its Falcon 9 rocket lifting off from Vandenberg in California.

The first stage completed its 26th flight, landing on a drone ship in the Pacific Ocean. It also completed this flight only 22 days after its last flight. As of posting the deployment of these payloads and satellites was on going.

The leaders in the 2025 launch race:

78 SpaceX
35 China
8 Rocket Lab
7 Russia

SpaceX now leads the rest of the world in successful launches, 78 to 58.
