France’s military awards orbital tug startup contract for transporting its “inspector” satellites

9:51 am

France’s Directorate General of Armament (DGA) has awarded the orbital tug startup Infinite Orbits a $58.3 million contract to develop a tug that can transport its military “inspector” technology to geosynchronous orbit when it can rendezvous and inspect other satellites.

Under the PALADIN framework agreement, Infinite Orbits will develop a dedicated spacecraft capable of delivering the geostationary orbit inspection and monitoring service that will be utilized by the country’s Commandement de l’Espace (CDE – Space Command). The spacecraft is expected to be ready for launch as early as 2027 and will be based on Infinite Orbits’ Orbit Guard offering.

Infinite Orbits is based in France, though it also has offices in the U.S. and Singapore. It has also flown one demo mission of its Orbit Guard tug, and won a contract for a later mission from France’s space agency CNES. It is also developing a satellite servicing robot dubbed Endurance.

Overall, Europe (and France surprisingly) has latched onto the capitalism model with amazing enthusiasm in the past two years, to a point that it might actually be doing it better than NASA. Europe doesn’t have a giant money-sucking government program like Artemis (though it is partnering on Artemis). Thus, it can spend its money in buying many different but needed space products from its private sector. And it has more money available for these purposes.

NASA can’t do this as effectively, because a much larger portion of its budget is trapped financing the ineffective SLS rocket and Orion capsule.

Two Japanese shipping companies are developing floating landing platforms for rockets

9:25 am

Two different Japanese shipping companies are now developing floating ship platforms that rocket companies could use to land their rocket’s first stages.

Japan’s Nippon Yusen Kaisha (NYK) is following compatriot Mitsui OSK Lines in targeting space exploration as a new source of revenues.

NYK has obtained an approval in principle from ClassNK for the conceptual design of an offshore recovery system for reusable rockets, an initiative developed through the Space Strategy Fund at the Japan Aerospace Exploration Agency (JAXA). NYK now aims to carry out a demonstration test of this new vessel type in 2028 working with multiple partners including Mitsubishi Heavy Industries.

Since JAXA and Mitsubishi own and build Japan’s new H3 rocket, JAXA’s funding here suggests both are considering upgrading the H3 for reusability. It is also possible Mitsubishi is mulling plans to build its own new commercial rocket.

Two companies to study ways for extending the life of the Gehrels Swift space telescope

9:15 am

NASA yesterday announced that it has awarded two companies, Cambrian Works in Virginia and Katalyst Space Technologies in Arizona, each $150K study contracts for reviewing whether it makes sense to send a robotic servicing mission to Gehrels Swift space telescope to raise its orbit and extend its life.

Since its launch in 2004, NASA’s Swift mission has led the agency’s fleet of space telescopes in investigating changes in the high-energy universe. The spacecraft’s low Earth orbit has been decaying gradually, which happens to most satellites over time. Because of recent increases in the Sun’s activity, however, Swift is experiencing additional atmospheric drag, speeding up its orbital decay. This lowering orbit presents an opportunity for NASA to advance a U.S. industry capability, while potentially extending the science lifetime of the Swift mission. The concept studies will help determine whether extending Swift’s critical scientific capabilities would be more cost-effective than replacing those capabilities with a new observatory.

According to this paper [pdf], the telescope’s orbit will decay before the end of 2029, so speed is of the essence. Why NASA is thus spending time and money on a “study” contract from companies that don’t do orbital servicing or have orbital tugs is very curious. Wouldn’t make more sense to request bids from the many orbital servicing and tug companies that now exist (D-Orbit, Astroscale, Northrop Grumman, Firefly, Blue Origin, Rocket Lab, Impulse) to see if any can do the job at a reasonable cost and are willing?

Gehrels Swift has proven to be one of the most valuable and useful high energy space telescopes ever launched. First of all its cost was relatively low. Second, it is designed to quickly observe a gamma ray burst (GRB) location in multiple other wavelengths (optical especially). That ability helped solve the mystery of GRBs, as well as numerous other high energy events. It would be a tragedy to lose it.

It would also be far more expensive to build a replacement.

Radar images of near Earth asteroid as it zipped past the Earth

9:11 am

Radar images of near Earth asteroid
Click for original. Go here for movie made from these images.

Using the Goldstone radar antenna in California, astronomers have produced a series of 41 radar images of the near Earth asteroid 2025 OW as it made a close pass of the Earth on July 28, 2025.

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

The asteroid safely passed at about 400,000 miles (640,000 kilometers), or 1.6 times the distance from Earth to the Moon.

The asteroid was discovered on July 4, 2025, by the NASA-funded Pan-STARRS2 survey telescope on Haleakala in Maui, Hawaii. These Goldstone observations suggest that 2025 OW is about 200 feet (60 meters) wide and has an irregular shape. The observations also indicate that it is rapidly spinning, completing one rotation every 1½ to 3 minutes, making it one of the fastest-spinning near-Earth asteroids that the powerful radar system has observed. The observations resolve surface features down to 12 feet (3.75 meters) wide.

The asteroid’s fast rotation suggests it is a solid object, structurally strong, rather than a rubble pile held together loosely by gravity. It would thus be very damaging if it should ever hit the Earth.

No worries however. The refined orbital data says this asteroid will not come this close again in the foreseeable future.

SpaceX launches 24 more Kuiper satellites for Amazon

8:35 am

SpaceX this morning successfully placed another 24 Kuiper satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The Falcon 9 first stage was new, completing its first flight by landing on a drone ship in the Atlantic. The two fairings completed their 5th and 28th flights respectively.

This was SpaceX’s second of three launches for Amazon, which now has 102 satellites in orbit. It needs to get another 1,498 in orbit by July 2026 in order to meet its licence requirements by the FCC. While ULA seems poised to begin regular launches for Amazon, having a contract for 46 launches (having so far completed two in 2025), the contracts for Blue Origin’s New Glenn (27 launches), and ArianeGroup’s Ariane-6 (18 launches) are more uncertain. Neither company has achieved any launches on their contracts, and it is not clear when either company, especially Blue Origin, will ever begin regular launches.

The leaders in the 2025 launch race:

98 SpaceX (with another Starlink launch scheduled for later today)
43 China
11 Rocket Lab
9 Russia

SpaceX now leads the rest of the world in successful launches, 98 to 74.

Toyota extends its partnership with Japanese rocket startup Interstellar

9:39 am

In a deal last week Toyota extended its partnership with the Japanese rocket startup Interstellar Technologies from its earlier announcement in January 2025 that it would invest $44 million in the company.

As part of the new agreement, Toyota will dispatch personnel starting in August 2025 to support Interstellar in a wide range of manufacturing efforts, from the development of ZERO’s first flight unit to broader business commercialization. Additionally, Interstellar became the first startup to join “Toyota Woven City” as an Inventor, leveraging Toyota’s decades of manufacturing expertise and strengths. The development of ZERO will continue to be based on Interstellar’s facilities.

Zero is Interstellar’s proposed smallsat rocket. The company, which was founded in 2005, attempted a suborbital launch in 2018 that failed. Until Toyota’s commitments this year, it had done almost nothing since.

FCC eliminates red tape for both satellite companies and space stations

9:29 am

The Federal Communications Commission (FCC) this week announced [pdf] that it has changed a number of regulations to streamline its licensing in connection with satellite constellations, ground stations, and new space stations.

Today’s reforms intend to boost the nascent Ground-Station-as-a-Service (GSaaS) business model that allows multiple satellite systems to share the same ground station. The new rules eliminate needless paperwork and clear regulatory barriers to GSaaS, a business model that gives satellite operators—especially startups and emerging growth companies—the ability to send and receive signals without having to build their own ground infrastructure.

…The Order establishes a new process for ground station operators to receive a baseline license without first identifying a specific satellite point of communication. For each new point of communication, only a simple FCC notification will be needed. This one change would eliminate approximately 49% of earth station modification applications.

Today’s action further streamlines and expedites the application process for space stations and earth
stations by moving away from regulations that require FCC approval for making even the smallest
changes to a satellite system.

The direction of regulation has shifted 180 degrees since Trump’s election. Under Biden, federal agencies were constantly tasked to increase oversight so that it often took years to get approvals. Under Trump, those same agencies are now beginning to eliminate regulation across the board.

Elections matter. Anyone who says all politicians are the same is either ignorant or lying.

Starlink now available in Israel

9:20 am

After a year of regulatory paperwork, the Israel government has finally allowed SpaceX to offer Starlink to customers in Israel proper, but not in the West Bank or Gaza.

The company received an operating license from the Communications Ministry last year, following lengthy negotiations and regulatory procedures, but its launch was delayed until now. The restriction on coverage in the West Bank and Gaza is likely due to security concerns over potential use by hostile actors.

Expect the usual leftist anti-Semites to accuse Israel of bigotry for excluding access to Palestinians, but until those Palestinians show some willingness to live with Israel in peace (something they so far show no signs in doing, especially in Gaza), this policy makes perfect sense.

Endurance capsule splashes down safely, returning four astronauts from ISS

8:56 am

SpaceX’s Endurance Dragon capsule successfully splashed down off the coast of California this morning, returning four astronauts from ISS after a five month mission.

I have embedded the live stream below. As of posting the capsule was about to be lifted from the water and placed in its nest on the recovery ship.

Once again it is important to note that this recovery is being done entirely by a private company and its employees. Once Endurance undocked from ISS NASA had no part to play. It purchased the ride from SpaceX, and SpaceX is providing the service.

China launches another 11 satellites for one of its mega-constellations

12:42 am

China's spaceports

China today successfully placed another 11 satellites into orbit for one of its internet satellite constellations designed to compete with Starlink, its Smart Dragon-3 rocket lifting off from a launch platform off the eastern coast of China.

This was the fourth launch of satellites for Geely constellation. Though the rocket’s lower stages dropped into the South China Sea as well as the Pacific, doing no harm to habitable areas (as China routinely does when it launches from its interior spaceports), earlier this week the president of the Philippines, Ferdinand Marcos Jr., complained about China’s habit of not giving its neighbors sufficient warning prior to its coastal launches.

Marcos issued the statement after China launched its Long March 12 rocket on Monday [from its coastal Wenchang spaceport], which left debris within Philippine maritime territory. During an interview with the Philippine media delegation covering his state visit to India, the President said this was not the first time suspected Chinese rocket debris had ended up in Philippine waters.

“Well, it’s not the first time that this has happened. And, actually, if you look at the incidents, they did not commit any violations. There have been no casualties,” Marcos said. “We just wish that perhaps they could warn us a little earlier so that we know the path of the rocket, where the path is, and if they will release stages, where they will fall,” he added.

All par for the course for China. It not only doesn’t really care if it crashes rocket stages on the heads of its own people, it cares even less about dropping stages on neighboring countries.

The leaders in the 2025 launch race:

97 SpaceX
43 China
11 Rocket Lab
9 Russia

SpaceX still leads the rest of the world in successful launches, 97 to 74.

Jim Lovell, the world’s first space cadet, passes away at 97

3:51 pm

Jim and Marilyn Lovell

U.S. Navy sailboat Freedom in 1950

Today we learned the sad news of the passing of Jim Lovell, the last of the three Apollo 8 astronauts as well as a veteran of two Gemini missions and the ill-fated Apollo 13 mission. Lovell was 97.

In a statement released Friday, the Lovell family highlighted his “amazing life and career accomplishments” and his “legendary leadership in pioneering human space flight.”

“But, to all of us, he was Dad, Granddad, and the Leader of our family. Most importantly, he was our Hero,” the family said in its statement. “We will miss his unshakeable optimism, his sense of humor, and the way he made each of us feel we could do the impossible. He was truly one of a kind.”

“One of a kind” is an understatement. » Read more

Indian rocket startup Skyroot tests solid-fueled motor

12:53 pm

The Indian rocket startup Skyroot has successfully tested the solid-fueled motor it plans to use in its three-stage solid-fueled Vikram-1 rocket. From the press release issued by India’s space agency ISRO:

First Static Test of the KALAM 1200 Motor – the first stage of Vikram – 1 Launch Vehicle of M/s Skyroot Aerospace Pvt. Ltd. (SAPL), Hyderabad is accomplished successfully at Static Test complex of Satish Dhawan Space Centre, Sriharikota, ISRO, Department of Space at 09:05 hrs on 08.08.2025. This is a major milestone in the configuration and realization of the systems for Vikram – 1 Launch Vehicle. The motor is a 11 m long, 1.7 m dia monolithic composite motor with a Propellant Mass of 30t. Based on the design inputs, this longest monolithic motor is prepared at the Solid Propellant Plant, Sriharikota. Similarly, ISRO team has provided the design for the Test Stand, which is used for the static test of the motor.

This is in line with the Government of India initiative on Space Policy, 2023 for providing the necessary technical infrastructure and managerial guidance for the Private Sector players to contribute for the space economic growth. The performance of the test bed and the associated systems is normal as predicted.

The last paragraph is the most important. The Modi government has tasked its space agency to provide its facilities and expertise to help rocket startups like Skyroot. It appears from this test and press release the resistance within ISRO to this policy — which cuts into ISRO’s turf — is fading.

Skyroot had said it wants to do the first orbital test flight of Vikram-1 before the end of 2025. It remains unclear whether it will meet that schedule.

Sending Juno to fly past interstellar comet 3I/Atlas?

10:42 am

3I/Atlas as seen by Hubble on July 21, 2025
Hubble’s most recent image of comet 3I/Atlas.
Click for original image.

It’s all clickbait! In what appears to be an example of silliness, a scientist, Avi Loeb of Harvard, has proposed repurposing the Jupiter orbiter Juno by using its remaining fuel and its main engine (unused since 2016 because it is feared it will explode if ignited) to send the spacecraft on a path allowing it to fly past the interstellar comet 3I/Atlas that is presently zipping through out solar system.

Not surprisingly, a politician, congresswoman Anna Paulina Luna (R-Florida), immediately latched onto this idea to garner her own publicity.

Loeb believes Juno, which is scheduled to plunge into Jupiter’s atmosphere at the end of its mission in Sept. 2025, could be repurposed. He suggests using its remaining fuel to redirect it toward 3I/ATLAS when the object passes within about 34 million miles of Jupiter in March 2026.

Florida Congresswoman Anna Paulina Luna has backed the proposal in a letter [pdf] to interim NASA Administrator Sean Duffy, urging the agency to explore extending Juno’s mission. “It is recommended that NASA conduct a study to assess how much fuel is left in Juno’s engine, and I support an extension of the Juno mission at least until mid-March 2026 at a cost of about $15M per 6 months from the current expiration date of mid-September 2025,” Luna wrote.

The problem with this idea is that it isn’t realistic. Juno really doesn’t have sufficient fuel, and as I mentioned, its main engine is suspect, so suspect that the science team decided in 2016 to never use it again, thus leaving Juno in a higher than planned orbit that required twice as much time at Jupiter to get the same work done.

There is also one more reason to doubt Loeb’s proposal. He has also proposed that 3I/Atlas is an alien probe, ignoring or dismissing the images and data that make if very clear that it is nothing more than a comet, albeit interstellar in origin. It appears therefore that he might very well represent the quality of scientists that Harvard is hiring these days.

Firefly’s stock value far exceeds the predicted price

9:41 am

When Firefly announced it was going public at the end of July, it predicted the stock price would range from $35 to $39, with the initial public offering raising about $600 million in capital for the company. Less than a week later it revised these predictions upward to $45 and about $700 million.

When trading opened yesterday, these numbers were still too low, with the stock immediately trading at $70 per share> and raising almost $900 million.

The space and defense technology company reached a peak valuation of more than $9.84 billion during intraday trading, after its shares began trading at $70 — up more than 55% from the initial public offering price of $45. The stock climbed as high as $73.80 during the session before closing at $60.35.

Firefly sold more than 19 million shares in the offering, raising at least $868 million. By the end of trading Thursday, total volume had approached 30 million shares.

This confidence and enthusiasm by Wall Street reflects Firefly’s success this year in becoming the first private company to land an unmanned spacecraft softly on the Moon. It also suggests the market expects the company’s orbital tug and rockets to succeed. Though its Alpha rocket has had a mixed record of success, its new larger Eclipse rocket is being built in partnership with Northrop Grumman, which has invested $50 million into its development.

Rocket Lab to unveil its completed Neutron launchpad by end of August

9:27 am

As part of a series of press releases in connection with the release of Rocket Lab’s second quarter financial report, the company announced that it is inviting shareholders to enter a sweepstakes for attending the official opening of its just completed launchpad at Wallops Island for its new Neutron rocket.

According to the announcement, the opening is scheduled for August 28, 2025.

Rocket Lab will randomly select ten (10) eligible entrants to win admission to the event. Eligible entrants are limited to U.S. citizens who are at least 18 years old and shareholders of Rocket Lab. Winners are responsible for their own travel and accommodation costs, and any other costs and expenses associated with traveling to and attending the event

The sweepstakes is a fun idea, but what is really significant is that the company appears to be continuing to meet its schedule for a first launch of Neutron before the end of 2025. If so it will be a major achievement, considering the company began work on this rocket in December 2021. To go from a blank sheet to launch in only four years is unprecedented. Normally it takes about twice as long to get a rocket to the launchpad.

Even if the launch date slips into the first quarter of 2026 the achievement will be spectacular.

Rocket Lab’s 2nd quarter financial report appears bright as well, noting a 36% increase in revenues from the previous year. While its rocket division continues to ramp up launches, the company has also done well diversifying into other space areas, from low Earth orbital constellations to deep space technology.

Azerbaijan officials hold cooperation talks with SpaceX

9:10 am

In connection with the visit of Azerbaijan’s president to the United States, he and other officials held a meeting with SpaceX vice president Stephanie Bednarek to discuss possible areas of cooperation. From Azerbaijan’s state-run press:

At the meeting, we noted Azerbaijan’s economic potential, strategic development directions, and favorable investment climate. We discussed prospects for cooperation with SpaceX, including partnership opportunities in the application of innovative and space technologies, artificial intelligence solutions, and knowledge and experience transfer.

In plain language, Azerbaijan is considering buying services from SpaceX. That it is doing so underlines once again the negative consequences of Putin’s invasion of the Ukraine. Azerbaijan now fears Russia, and is looking elsewhere for aid. It also senses Russia’s increasing weakness, economically, technologically, and militarily, making it more willing to forge alliances with others.

ULA’s CEO provides update on Vulcan and the company’s launch plans

9:03 am

Link here. ULA’s CEO Tory Bruno outlined the overall state of the company’s launch plans, including its goal of ramping up the launch rate by the end of this year to what Bruno had hoped to achieve at this start of 2025.

ULA anticipates a robust schedule, aiming for about two launches per month across its Atlas and Vulcan fleets in 2025 and 2026, “unless something interesting happens.”Bruno expressed confidence in achieving nine launches this year, bolstered by the completion of a new Vertical Integration Facility (VIF) and Mobile Launch Platform (MLP), enabling parallel rocket assembly.

In December 2024 Bruno had predicted the company would complete 20 launches in 2025. Right now it has only completed two launches (one each for Vulcan and Atlas-5). Getting up to 9 launches by the end of this year will require it to go from one launch every four months to two launches per month, and do so immediately. In its entire history the company has never come close to achieving that launch pace. The best it ever did was 16 launches in 2009.

That pace will also rely on Blue Origin delivering enough BE-4 engines for Vulcan’s first stage. According to Bruno, Blue Origin is now getting it done, and “might be an engine or two ahead.”

Intuitive Machines buys long-established space navigation company Kinetx

3:06 pm

The lunar lander startup Intuitive Machines has now acquired the long-established deep space navigation company Kinetx, based in Arizona.

With a heritage of supporting NASA and National Security Space missions, and as the only commercial company certified by NASA for deep space navigation, KinetX provides flight dynamics capabilities for both lunar and interplanetary missions. Its proprietary navigation software stack has supported both of Intuitive Machines’ lunar missions to date.

Despite the failure of two lunar landers, both of which tipped over upon landing, Intuitive Machines is still alive. It has more lunar landers in the pipeline, as well as a returnable capsule for space manufacturing.

Webb: Evidence of gas giant exoplanet orbiting the central star of Alpha Centuri

2:54 pm

Webb infrared data
Click for original image.

The uncertainty of science: Astronomers using the Webb Space Telescope now think they have detected a gas giant exoplanet orbiting the central star of the Alpha Centuri triple star system, the closest star to our Sun at only four light years distance.

The false-color image to the right shows the candidate exoplanet labeled as S1, with the light of the central star blocked out but indicated by the star at the center. A lot of processing was required to bring out this bright blob, including eliminating optical effects that normally act to hide such objects.

Alpha Centauri, located in the far southern sky, is made up of the binary Alpha Centauri A and Alpha Centauri B, both Sun-like stars, and the faint red dwarf star Proxima Centauri. Alpha Centauri A is the third brightest star in the night sky. While there are three confirmed planets orbiting Proxima Centauri, the presence of other worlds surrounding Alpha Centauri A and Alpha Centauri B has proved challenging to confirm.

Now, Webb’s observations from its Mid-Infrared Instrument (MIRI) are providing the strongest evidence to date of a gas giant orbiting Alpha Centauri A. …Based on the brightness of the planet in the mid-infrared observations and the orbit simulations, researchers say it could be a gas giant approximately the mass of Saturn orbiting Alpha Centauri A in an elliptical path varying between 1 to 2 times the distance between Sun and Earth.

If confirmed the exoplanet would be orbiting the star within the habitable zone, though as a gas giant life as we know it would likely be impossible. The location, only four light years away, makes this exoplanet and the entire system a prime target for further observations.

India’s Chandrayaan-2 lunar orbiter has now produced a new high resolution image of Intuitive Machines’ Athena lander, sitting on its side inside a small crater near the Moon’s south pole.

The IM-2 ‘Athena’ lander attempted a soft touchdown near the Moon’s South Pole on 6 March, 2025. Although the lander remained intact, it failed to reach its intended landing spot and ended up tipping over on its side inside a crater.

In the … images taken by the OHRC instrument on board the Chandrayaan-2 Orbiter, the Athena lander can be clearly seen lying on its side inside a crater.

This image, posted to the right, compares very favorably with the photos taken by Lunar Reconnaissance Orbiter (LRO) in March 2025. The lander’s legs can clearly be seen sticking out toward the top of the picture.

Strange rocks on Mars

Coral on Mount Sharp!

Float rock in Jezero Crater
Click for original image.

Time for two cool images, from two different craters separated by thousands of miles on Mars! The first image to the right, cropped, reduced, and sharpened to post here, was taken on July 24, 2025 by the Mars Hand Lens Imager (MAHLI) at the end of the robot arm of Mars rover Curiosity, and shows a really strange rock formation that resembles a piece of coral on Earth.

Curiosity has found many small features like this one, which formed billions of years ago when liquid water still existed on Mars [in this region]. Water carried dissolved minerals into rock cracks and later dried, leaving the hardened minerals behind. Eons of sandblasting by the wind wore away the surrounding rock, producing unique shapes.

The second image, cropped, reduced, and sharpened to post here, was taken on August 5, 2025 by the left high resolution camera on the rover Perseverance. It shows what appears what geologists call a “float rock”, something that was created geologically somewhere else and transported to this location later.

In this case the rock appears lavalike in nature. Since Perseverance is exploring the exterior rim of Jezero Crater, we could be looking at the impact melt created when the bolide hit the ground to create the crater. Material would be instantly melted as well as flung outward as ejecta, with this strangely shaped rock an example.

The problem with this theory however is that the rock appears to have solidified well before it hit the ground at this location. Its shape also suggests it solidified within a crack, thus molding it to this shape, with its top once at the bottom, the lava flowing downward. The mystery then is how it ended up as we see it, upside down and exposed.

Virgin Galactic delays first flight of its new suborbital craft while cutting workforce

10:50 am

Virgin Galactic has trimmed its work force by 7% even as it announced a delay in the first flight of its new Delta suborbital spacecraft from this summer to the fall.

Virgin Galactic Holdings Inc. cut 7% of its workforce as it works to bring to market an upgraded spaceplane central to its plans to expand suborbital tourism and research operations.

The Richard Branson-founded company plans to resume private space tourism trips in the autumn of 2026 after its Delta spacecraft’s first commercial flight, a research mission that was delayed from summer 2026 to also occur in the fall.

It still remains to be seen whether the business model for suborbital hops is viable and profitable. Blue Origin’s New Shepard has been flying somewhat regularly, and appears to have a customer base, but whether it is making a profit remains unknown. Virgin Galactic is deep in the red, and has done no flights for several years as it builds a new spacecraft. Both face stiff competition from the orbital market, which offers a much better product though at a much higher price.

New Hubble observations of Comet 3I/Atlas refine its size

3I/Atlas as seen by Hubble on July 21, 2025
Click for original image.

Using the Hubble Space Telescope, astronomers have refined significantly the size of the interstellar object Comet 3I/Atlas as it zips through the solar system in its journey through the galaxy.

The image to the right, cropped and reduced to post here, is a Hubble image taken on July 21, 2025. The streaks are background stars.

Hubble’s observations allow astronomers to more accurately estimate the size of the comet’s solid, icy nucleus. The upper limit on the diameter of the nucleus is 3.5 miles (5.6 kilometers), though it could be as small as 1,000 feet (320 meters) across, researchers report. Though the Hubble images put tighter constraints on the size of the nucleus compared to previous ground-based estimates, the solid heart of the comet presently cannot be directly seen, even by Hubble.

…Hubble also captured a dust plume ejected from the Sun-warmed side of the comet, and the hint of a dust tail streaming away from the nucleus. Hubble’s data yields a dust-loss rate consistent with comets that are first detected around 300 million miles from the Sun. This behavior is much like the signature of previously seen Sun-bound comets originating within our solar system.

In other words, though this object comes from far outside our solar system, it so far appears to closely resemble comets from our own system. If confirmed, this fact is quite significant, as it suggests the formation of solar systems throughout the galaxy are likely to be relatively similar to our own.

Italy to fly experiments on first Starship flights to Mars

10:31 am

According to a tweet by SpaceX’s president and chief operating officer Gywnne Shotwell today, the Italian Space Agency (ASI) has signed an agreement to fly experiments on first Starship flights to Mars that will carrying customer payloads. She quoted a tweet by ASI’s president, Teodoro Valente:

ASI_Spazio and SpaceX have signed a first-of-its-kind agreement to carry Italian experiments on the first Starship flights to Mars with customers. The payloads will gather scientific data during the missions. Italy continues to lead in space exploration!

Little other information has yet been released, but expect more details in the coming days.

UPDATE: ASI’s press release on August 8th added this detail:

The payloads will include a plant growth experiment, a weather monitoring station and a radiation sensor. The goal is to collect scientific data in the approximately six-month interplanetary flight phase from Earth to Mars and then on the Martian surface.

Hera photographs two main belt asteroids on its way to Didymos/Dimorphos

Asteroid Otero as seen by Hera
Click for original image.

The science team for the European Space Agency’s Hera asteroid probe, on its way to the binary asteroid Didymos/Dimorphos in late 2026, has successfully taken images of two different main belt asteroids, demonstrating once again that its camera and pointing capabilities are operating as expected.

The image to the right, cropped, reduced, and enhanced, shows all the observations of Otero, the first asteroid observed, as it moved upward in the field of view. The result was that vertical line of dots.

On 11 May 2025, as Hera cruised through the main asteroid belt beyond the orbit of Mars, the spacecraft turned its attention toward Otero, a rare A-type asteroid discovered almost 100 years ago.

From a distance of approximately three million kilometres, Otero appeared as a moving point of light – easily mistaken for a star if not for its subtle motion across the background sky. Hera captured images of Otero using its Asteroid Framing Camera – a navigational and scientific instrument that will be used to guide the spacecraft during its approach to Didymos next year.

The second observation of asteroid Kellyday was even less spectacular visually, but because that asteroid was forty times fainter than Otero, the observation was more challenging, and thus its success more significant.

Hera will arrive at the Didymos/Dimorphos binary asteroid in 2026, where it will make close-up observations of the changes the asteroids have undergone following Dart’s impact of Dimorphos in 2022. Subsequent ground- and space-based observations have been extensive and on-going, but the close-up view will be ground-breaking.

China announced today that it has successfully completed landing and take-off tests of its manned lunar lander.

That lander is shown to the right, its engines firing as its likely descends, held up by cables to simulate the lunar gravity. From the caption:

This file photo shows a manned lunar lander during a trial at a test site in Huailai County, north China’s Hebei Province. China on Thursday announced that it has successfully completed a comprehensive test for the landing and takeoff of its manned lunar lander at a test site in Huailai County, Hebei Province.

The test completed on Wednesday represents a key step in the development of China’s manned lunar exploration program, and it also marks the first time that China has carried out a test for extraterrestrial landing and takeoff of a manned spacecraft, said the China Manned Space Agency.

History buffs will immediately notice the similarity of this lander to the Lunar Module (LM) that the U.S. used during the Apollo missions. What is not clear is whether the lander will have a separate descent and ascent stage, as the LM did, and if so, whether these flight tests included separate operations of each.

Acting NASA head Duffy reshapes NASA’s space station plans

9:36 am

Sean Duffy
Sean Duffy, transportation secretary and interim
NASA administrator

Earlier this week NASA’s interim administrator Sean Duffy issued a new directive [pdf] that fundamentally reshaped the agency’s space station program in how it will fund and operate the private commercial space stations now under development.

Under the present plan, NASA had issued development contracts to three proposed commercial stations, with a major contract award expected next year to one of the four companies/consortiums that are bidding. Duffy instead wants NASA to fund all the stations in an open-ended manner.

Instead of moving forward in Phase 2 with a firm fixed price contract for [commercial station] certification and services, NASA will continue to support U.S industry’s design and demonstration of [commercial stations] with multiple funded SAAs [Space Act Agreements] for the next phase. NASA will shift the formal design acceptance and certification planning acceptance from this SAA phase to a follow-on certification phase.

Utilizing SAAs for the next phase better aligns with enabling development of US industry platforms. It provides greater resources for industry to align schedule with NASA’s needs. SAAs also provide more flexibility to deal with possible variations in funding levels without the need of potentially protracted and inefficient contract renegotiations.

SAAs are generally fixed price, but the structure Duffy is establishing appears to allow NASA to supplement these contracts endlessly, making them a kind of hybrid cost-plus deal. It also aims at supporting “a minimum of two, preferably three or more” of the private stations under development.

Duffy’s shift to SAAs will also give the private stations more design and operational freedom, as SAAs shift responsibility and ownership to the company, not NASA. The arrangement will also likely require a larger investment by the companies, though this is not clear in Duffy’s directive.

Firefly’s stock sells at price higher than expected

8:54 am

Firefly began selling stock to the public today on the Nasdaq stock market, with the price per share immediately rising to $45 per share, above the expected range of $41-$43, suggesting it could raise as much as$868 million in investment capital.

The strong interest in the stock by investors suggests there is great confidence in the company’s future, following the successful landing of its Blue Ghost lunar lander earlier this year. It has won a total of four lander contracts from NASA. The company also has won both commercial and NASA contracts in connection with its Elytra orbital tug. It has had mixed results with its Alpha rocket, experiencing both launch failures as well as successes, but it is also developing a larger rocket in partnership with Northrop Grumman.

This enthusiasm is noteworthy in that the company is not yet in the black, though its revenues have been increasing.

For the quarter that ended in March, Firefly reported a net loss of about $60.1 million, widening from $52.8 million in the year-ago period. Revenue jumped sixfold to $55.9 million from $8.3 million. Its backlogged totaled about $1.1 billion.

Overall it appears Firefly’s future is solid, suggesting it will join SpaceX and Rocket Lab as a major new space player in the coming years.

NASA officially ends failed Lunar Trailblazer mission

9:27 am

NASA on August 4, 2025 officially ended its months-long effort to recover its Lunar Trailblazer mission that failed almost immediately after launch in February.

Lunar Trailblazer shared a ride on the second Intuitive Machines robotic lunar lander mission, IM-2, which lifted off at 7:16 p.m. EST on Feb. 26 aboard a SpaceX Falcon 9 rocket from the agency’s Kennedy Space Center in Florida. The small satellite separated as planned from the rocket about 48 minutes after launch to begin its flight to the Moon. Mission operators at Caltech’s IPAC in Pasadena established communications with the small spacecraft at 8:13 p.m. EST. Contact was lost the next day.

Without two-way communications, the team was unable to fully diagnose the spacecraft or perform the thruster operations needed to keep Lunar Trailblazer on its flight path.

This failure of a NASA-built and operated lunar orbiter contrasts starkly with the success of the privately-built and operated Capstone mission. Contact with that spacecraft, built by Rocket Lab, was also lost soon after launch, but the company doing mission control, Advanced Space, was able to re-establish contract and get the spacecraft into lunar orbit, where it continues to function as planned.

Confusion reigns as to what shuttle will be moved to Houston, if any

9:20 am

Despite amendments in the reconciliation bill that said the space shuttle Discovery held by the Smithsonian in DC would be transferred to Houston for display, it appears there is uncertainty and confusion as to what shuttle will be moved, above and beyond the Smithsonian’s opposition to this transfer.

The legislation that required Duffy to choose a “space vehicle” that had “flown in space” and “carried people” did not specify an orbiter by name, but the language in the “One Big Beautiful Bill” that President Donald Trump signed into law last month was inspired by Cornyn and fellow Texas Senator Ted Cruz’s bill to relocate Discovery. “The acting Administrator has made an identification. We have no further public statement at this time,” said a spokesperson for Duffy in response to an inquiry by collectSPACE.

It appears Duffy’s options are limited. NASA no longer has any title or ownership rights to the shuttles held by the Smithsonian and the California Science Center in Los Angeles. It owns the only remaining shuttle, Atlantis, which it has on display in Florida, but moving that to Houston would entail big political warfare.
