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.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

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.”

Thank you all!

11:21 pm

For the most recent posts, scroll down.

My July fund-raising campaign to celebrate the fifteenth anniversary since I began Behind the Black is now over. I want to thank all those who so generously donated or subscribed, especially those who have become regular supporters. I can’t do this without your help. I also find it increasingly hard to express how much your support means to me. God bless you all!

The donations during this year’s campaign were sadly less than previous years, but for this I blame myself. I am tired of begging for money, and so I put up the campaign announcement at the start of the month but had no desire to update it weekly to encourage more donations, as I have done in past years. This lack of begging likely contributed to the drop in donations.

No matter. I am here, and here I intend to stay. If you like what I do and have not yet donated or subscribed, the instructions for doing so can be found elsewhere on this page.

This post will remain at the top of the page for the next few days so that everyone who donated can see my thanks!

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.

Sources suggest major job layoffs and salary cuts about to sweep Russia

2:35 pm

According to various sources, major job layoffs and salary cuts are about to sweep Russia, affecting 800,000 people working for nine different large companies.

The cuts include layoffs, salary cuts, shortened work hours, and unpaid leave, with many involved in the aviation industry.

According to the tweet at the link, the blame goes to the Ukraine war and the collapse of the Russian economy because of it. That might or might not be true, but the speculation is certainly reasonable.

This collapse has been predicted now for several years. If it happens Putin’s future as head of Russia might finally be reaching its use-by date.

India’s Chandrayaan-2 lunar orbiter photographs Intuitive Machines’ Athena lander

2:27 pm

Athena as seen by Chandrayaan-2
Click for source.

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.

Astronomers claim to discover biggest supermassive black hole yet

2:17 pm

The Cosmic Horseshoe
Click for original image.

The uncertainty of science: Astronomers now believe they have discovered the heaviest supermassive black hole yet found, with a mass thought to be equivalent to 36 billion solar masses and located at the center of a distant galaxy they have dubbed The Cosmic Horseshoe.

The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope. You can read the science paper here.

Researchers detected the Cosmic Horseshoe black hole using a combination of gravitational lensing and stellar kinematics (the study of the motion of stars within galaxies and the speed and way they move around black holes). The latter is seen as the gold standard for measuring black hole masses, but doesn’t really work outside of the very nearby universe because galaxies appear too small on the sky to resolve the region where a supermassive or ultramassive black hole lies.

Adding in gravitational lensing helped the team “push much further out into the universe”, Professor Collett said.

There is a blue-colored galaxy directly behind the Horseshoe, whose light is lensed into the blue circle as it passes through the black hole’s massive gravitational field.

It is believed, based on present theories, that this black hole is at the uppermost limit possible in mass. It also must be underlined that there are many uncertainties in this data.

Strange rocks on Mars

Coral on Mount Sharp!
Click for original image.

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

10:42 am

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

10:12 am

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 completes landing and take-off tests of its manned lunar lander

China's manned lunar lander during landing and take-off tests
Click for original image.

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.

Sunspot update: The Sun appears ready to once again confound the experts

1:12 pm

It is the start of the month and time once again for my monthly sunspot update, using the update that NOAA posts each month to its own graph of sunspot activity but annotated by me with extra information to illustrate the larger scientific context.

This month’s update graph is below, and it shows once again that it is a big mistake to put any faith into any prediction anyone makes about the Sun’s eleven-year sunspot cycle, tracked by scientists since the 1700s. Beginning in April 2025 the NOAA solar science panel has been predicting that the solar maximum had hit its peak and that we should expect the Sun to begin its ramp down to solar minimum, expected around 2031.

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.

Astroscale awarded patent for its space junk removal technology

9:03 am

Astroscale's patented design
Astroscale’s patented design. Click for original.

The Japanese orbital tug and space junk removal startup Astroscale was awarded a U.S. patent in late July for its space junk removal technology.

Under this new patented method, the servicer docks with a debris object (the “client”) and transfers it to a reentry shepherd vehicle in a lower orbit. Once the client is docked with the shepherd, the servicer separates and proceeds to engage a new client, while the shepherd safely guides the initial client into Earth’s atmosphere for reentry. This process repeats, allowing the servicer to remove multiple large debris objects over the course of its mission.

Astroscale’s architecture also supports flexible mission profiles: the shepherd can remain docked through reentry, undocked after performing reentry insertion and returned to orbit, or in some cases, missions can proceed without a shepherd vehicle at all. This adaptability is essential in addressing the diverse size and risk profile of objects in orbit.

The company notes that this technology, which the image suggests will use robot arms to grab its targets, will allow its spacecraft to remove not only inactive satellites that were launched with docking equipment already attached but also rocket bodies and older satellites without that docking capability.

Duffy touts nuclear power for lunar base

8:53 am

NASA administrator

NASA’s interim administrator Sean Duffy yesterday issued a directive touting the need to develop nuclear power for NASA’s planned lunar base. His comments during a press conference yesterday underlined his position.

Listen, this is not a new concept. This has been discussed under Trump One, under Biden, but we are in a race, we’re in a race to the Moon, in a race with China to the Moon. And to have a base on the Moon, we need energy. And some of the key locations on the Moon, we’re going to get solar power. But this fission technology is critically important, and so we’ve spent hundreds of millions of dollars studying can we do it? We are now going to move beyond studying and we are going, we have given direction to go. Let’s start to deploy our technology, to move, to actually make this a reality.

And I think the stat we have is 100 kilowatt output. That’s the same amount of energy a 2,000 square foot home uses every three-and-a-half days. So we’re not talking about massive technology. We’re not launching this live, that’s obviously, if you have any questions about that, no, we’re not launching it live [activated].

This is all blather designed to push Artemis and SLS and Orion. Duffy also once again touted the next Artemis mission, Artemis-2, that will use SLS and Orion to send astronauts around the Moon in April 2026, acting as if he had no idea about the mission’s known technical risks. He also insisted the lunar landing would follow soon thereafter.

More and more it appears to me that Trump dumped Jared Isaacman because it was almost certain Isaacman — with his own personal experience as an astronaut — would have likely refused to permit astronauts to fly on Artemis-2 because of Orion’s heat shield issues as well as its untested environmental systems. Duffy meanwhile is acting as a company man, pushing the program hard while ignoring the real risks. It appears Trump wants that manned lunar landing before he leaves office, and will brook no hesitation from anyone.

Welcome to Challenger and Columbia, all over again. Politics and scheduling has become paramount, while engineering takes a back seat.

NASA awards small orbital tug study contracts to six companies

8:35 am

NASA yesterday awarded six companies small study contracts in connection with orbital tug operations, with some to study using their rocket upper stage for this purpose while others to see how they can refine the use of their tugs.

The press release was not entirely clear on how much money was involved in each contract, though in each case the amounts are relatively small.

The firm-fixed-price awards comprise nine studies with a maximum total value of approximately $1.4 million. The awardees are:

Arrow Science and Technology LLC, Webster, Texas [tug study]
Blue Origin LLC, Merritt Island, Florida [both tug and upper stage studies]
Firefly Aerospace Inc., Cedar Park, Texas [tug study]
Impulse Space Inc., Redondo Beach, California [tug study]
Rocket Lab, Long Beach, California [both tug and upper stage studies]
United Launch Services LLC, Centennial, Colorado [upper stage study]

The studies are expected to be finished by September 2025, and will be used by NASA to determine how it will get some of its future spacecraft to their intended orbits.
