Indian rocket startup Skyroot tests solid-fueled motor

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 โ€“ the first stage of Vikram โ€“ 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 โ€“ 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?

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.

Azerbaijan officials hold cooperation talks with SpaceX

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.

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

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

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.

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

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 industryโ€™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 NASAโ€™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.

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

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.

NOT!

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

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.

Duffy touts nuclear power for lunar base

Sean Duffy
Sean Duffy, transportation secretary and interim
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, weโ€™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, weโ€™re going to get solar power. But this fission technology is critically important, and so weโ€™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. Letโ€™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. Thatโ€™s the same amount of energy a 2,000 square foot home uses every three-and-a-half days. So weโ€™re not talking about massive technology. Weโ€™re not launching this live, thatโ€™s obviously, if you have any questions about that, no, weโ€™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

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.
