NASA and Northrop Grumman work out rendezvous plan to get Cygnus to ISS

11:08 pm

UPDATE: The plan worked and Cygnus is safely berthed at ISS.

According to a press release tonight, NASA and Northrop Grumman have figured out a new rendezvous plan to get Cygnus to ISS after its previous engine burns yesterday cut off prematurely and left it in the wrong orbit.

NASA and Northrop Grumman are targeting the safe arrival of the company’s Cygnus XL at approximately 7:18 a.m. EDT Thursday, Sept. 18, to the International Space Station. The Cygnus XL now will conduct a series of burns to bring the spacecraft to the space station for its robotic capture and installation.

NASA astronaut Jonny Kim is scheduled to capture Cygnus XL using the station’s Canadarm2 robotic arm with backup support from NASA astronaut Zena Cardman. After capture, the spacecraft will be installed on the Unity module’s Earth-facing port and will remain at the space station until March 2026.

The release also added this detail about why that engine burn ended too soon:

Data shared by the spacecraft confirmed that Cygnus XL operated as intended during two planned maneuvers when an early warning system initiated a shutdown command and ended the main engine burn because of a conservative safeguard in the software settings.

Apparently this cause has reassured them that the engine is in good shape for the final rendezvous burns.

Monitoring the largest recent impact detected by InSight’s seismometer

11:51 am

Overview

Cool image time! On December 24, 2021 the seismometer of the Mars lander InSight detected a four magnitude earthquake, the largest detected up until then. Because its nature suggested that it had been caused by an impact, not an internal shifting, the science team for Mars Reconnaissance Orbiter (MRO) immediately started searching for new impact craters in the area of Mars where the data suggested the quake came from.

Two months later they found it, in the northern lowland plains just south of the prime landing zone chosen by SpaceX for its Starship spacecraft. The black cross on the overview map to the right indicates the position. The four red spots are the prime Starship landing sites. The white dots indicate other locations considered. The black dots were images taken for a proposed Dragon landing. This impact is thus only about 100 miles away from the nearest possible Starship landing spot.

Premature engine cutoff forces postponement of Cygnus berthing to ISS

11:16 pm

During the second of two engine burns today, designed to raise the orbit of Northrop Grumman’s Cygnus freighter to match ISS’s, the burn ended prematurely, placing the capsule in the wrong orbit.

Early Tuesday morning, Cygnus XL’s main engine stopped earlier than planned during two burns designed to raise the orbit of the spacecraft for rendezvous with the space station, where it will deliver 11,000 pounds of scientific investigations and cargo to the orbiting laboratory for NASA. All other Cygnus XL systems are performing normally.

The berthing, using one of the robot arms on ISS, had been planned for early tomorrow, Wednesday, but will not occur until both NASA and Northrop Grumman engineers have analyzed the issues and come up with “an alternate burn plan”.

Strange unexplained polarization shifts in M87’s supermassive black hole

12:25 pm

The changing magnetic field of M87
Click for original image.

Using the Event Horizon Telescope (EHT), astronomers have detected unexpected and so far unexplained polarization shifts in the supermassive black hole that resides at the center of the galaxy M87, located 55 million light years away.

That black hole is estimated to have a mass six billion times that of our Sun, and was the first ever imaged by EHT. By using observations made in 2017, 2018, and 2021, as shown in the images to the right, found its magnetic field changing in unexpected ways.

Between 2017 and 2021, the polarization pattern flipped direction. In 2017, the magnetic fields appeared to spiral one way; by 2018, they settled; and in 2021, they reversed, spiraling the opposite direction. Some of these apparent changes in the polarization’s rotational direction may be influenced by a combination of internal magnetic structure and external effects, such as a Faraday screen. The cumulative effects of how this polarization changes over time suggests an evolving, turbulent environment where magnetic fields play a vital role in governing how matter falls into the black hole and how energy is launched outward.

The changes were more puzzling in that the size of the black hole’s event horizon, the ring surrounding it, did not change. According to the scientists, this suggests “magnetized plasma swirling near the event horizon is far from static; it’s dynamic and complex, pushing our theoretical models to the limit.”

That the magnetic field flipped polarity however should not be surprising to scientists. Consider the same polarity flips we see in our own Sun every eleven years. It should be expected that the magnetic field around a super massive black hole would be equally variable, if not more so.

The problem is that there remains no understanding about why such changes happen. We know the magnetic field exists. We know it flips polarity. With the Sun we know it does so regularly every eleven years. Why it does so however remains unknown, though there are theories. With M87 the data is far less certain.

Tracking the changes at M87 however should help us build our knowledge base so that someday we might finally grasp those fundamentals.

Isar outlines what caused the failure on the first launch of its Spectrum rocket

11:13 am

Isar's first launch attempt fails
Spectrum falling seconds after launch

According to officials of the German rocket startup Isar Aerospace, its Spectrum rocket failed during its first launch in March 2025 because of a loss of attitude control, which then caused the rocket to self-destruct.

Alexandre Dalloneau, vice president of mission and launch operations at Isar, said that the company had not properly characterized bending modes of the vehicle at liftoff. “The controllability has to be tuned in order to counter such behavior,” he said. That environment was not fully modeled and incorporated into the vehicle’s control system. “We were outside the environment that we expected, so that the controllability does not succeed.”

That loss of attitude control caused the vehicle to go outside the safety zone at the launch site. That, in turn, triggered the flight termination system on the rocket. He said the company has revised its modeling of vehicle modes at liftoff to correct the problem.

The company is now working towards a second launch from Norway’s Andoya spaceport, which it hopes to attempt either late this year or early next year. Afterward it hopes to launch eight-plus times a year, based on the demand it is presently seeing for its rocket.

Europe once again delays test flights of its Callisto 1st stage hopper

11:05 am

Callisto's basic design
Callisto’s basic design

First proposed in 2015 as Europe’s answer to SpaceX’s Falcon 9, the first test flights of the European Space Agency (ESA)’s Callisto grasshopper-type reusable test prototype, as shown on the right, has once again been delayed, now from 2026 to 2027.

On Friday, CNES published a call seeking a partner to provide mechanical operations and procedures support ahead of the Callisto flight-test campaign, including contributions to operations user manuals, drafting mechanical operation procedures, and conducting detailed studies of mechanical interfaces between the vehicle and the ground segment. In the preamble to the scope of work, the notice states that the campaign will be carried out from the Guiana Space Centre in French Guiana in 2027. It will include an integration phase followed by eight test flights and two demonstration flights, all to be completed over a period of eight months.

The project, in which Japan’s space agency JAXA is participating, had an initial budget of $100 million, and originally planned to do its first hops in 2020. Instead, ESA spent a dozen years making powerpoint presentations, while SpaceX flew hundreds of operational flights with its Falcon 9, for profit.

Worse, this program is not attached to any rocket. It is a dead end. ESA and JAXA might get some useful engineering data from it, but it will belong to no one, and it is unclear anyone will care. At this moment it appears several private companies in Europe will have flown their own new rockets before Callisto even gets off the ground, and the data from those real rocket launches will be much more useful to them down the road.

Lucy scientists name the features on asteroid Donaldjohanson

10:16 am

The named features on Donaldjohanson
Click for original.

The science team for the asteroid probe Lucy have now released their names for the features they discovered on the main belt asteroid Donaldjohanson when the spacecraft flew past in April 2025.

The smaller lobe is called Afar Lobus, after the Ethiopian region where Lucy and other hominin fossils were found. The larger lobe is named Olduvai Lobus, after the Tanzanian river gorge that has also yielded many important hominin discoveries.

The asteroid’s neck, Windover Collum, which joins those two lobes, is named after the Windover Archeological Site near Cape Canaveral Space Force Station in Florida — where NASA’s Lucy mission launched in 2021. Human remains and artifacts recovered from that site revolutionized our understanding of the people who lived in Florida around 7,300 years ago.

Two smooth areas on the asteroid’s neck are named Hadar Regio, marking the specific site of Johanson’s discovery of the Lucy fossil, and Minatogawa Regio, after the location where the oldest known hominins in Japan were found. Select boulders and craters on Donaldjohanson are named after notable fossils ranging from pre-Homo sapiens hominins to ancient modern humans.

These names were “approved” by the International Astronautical Union (IAU), which claims the authority over the naming of every rock, boulder, pebble in space. The truth is, however, that future spacefarers are going to accept these names no matter what the IAU had said, simply because these scientists did the first exploration of this asteroid. They get to choose, not the IAU.

The spacecraft is now on its long coast out of the main belt and on to the orbit of Jupiter, where it will make fly-bys of ten different asteroids.

Scientists at JPL now predict a major long term uptick in sunspot activity

9:59 am

The solar science community's failed predictions
The many failed recent predictions of the
solar science community

The uncertainty of science: According to a NASA press release today, scientists at JPL now predict that the Sun will see a major increase in sunspot activity in the coming decades, ending the relatively quiet period seen in the two past solar maximums.

In their paper, the scientists say they come to this conclusion due to changes seen in solar wind activity since 2008. From their abstract:

Over the course of two decades until 2008, the solar wind became significantly weaker with a constant declining trend in many important solar wind parameters, and solar cycle 24 being the weakest on record since the start of the space age. Here we show that since 2008, the Sun has reversed this long-term weakening trend with a steady increase in various solar wind proton parameters observed at 1 au. Furthermore, comparison of values from a fitted trend to data between 2008 and 2025 show the following increases in solar wind proton parameters: speed (~6%), density (~26%), temperature (~29%), thermal pressure (~45%), mass flux (~27%), momentum flux or dynamic pressure (~34%), energy flux (~40%), interplanetary magnetic field magnitude (~31%), and the radial component of the magnetic field (~33%).

This has important implications on long-term solar trends, implying that the exceptional weakness of solar cycle 24 was most likely a recent outlier and that the Sun is not entering a modern era Maunder/Dalton-like minimum phase in its solar variation, but is instead recovering from a ~20 yr decline.

This analysis and conclusion is most intriguing, but we must also remember that every prediction by the solar science community in the past two decades has turned out to be wrong, as illustrated by the graph above. This prediction is just like all those others, in that it is based not on any fundamental understanding of why these changes in the solar wind are occurring, but simply extrapolating this past behavior into the future, a very unreliable method of prediction.

These scientists might be correct, but I would not bet any money on it.

China today successfully launched a satellite for testing “satellite internet technology”, its Long March 2C rocket lifting off from its Jiuquan spaceport in northwest China.

Its state-run press provided no other information about the satellite. Nor did it provide any information about where the rocket’s lower stages — which use toxic hypergolic fuels — crashed inside China.

The causes behind the launch failure of Firefly’s Alpha rocket in April

9:20 am

In late August the FAA and Firefly completed the investigation into the launch failure of Firefly’s Alpha rocket in April, clearing the way for the company to resume launches.

At the time however this approval was reported here merely as a quick link on X. The company however also published its conclusions at that time which explained the cause of the failure. For completeness I post that now, describing what happened just after the first stage separated from the second stage.

Alpha’s first stage then experienced a rupture milliseconds after stage separation. The pressure wave hit Alpha’s second stage, leading to the loss of the engine’s nozzle extension and substantially reducing stage two thrust. The second stage was able to recover attitude control and continued to ascend to an altitude of 320 km until running out of propellant. The vehicle was three seconds short of achieving orbital velocity and five seconds short of the target payload deployment orbit.

The ground-based video, onboard telemetry, post-flight empirical testing and Computational Fluid Dynamics analysis corroborated excessive heat from Plume Induced Flow Separation as the most probable root cause of the mishap. Alpha Flight 6 flew a higher angle of attack than prior missions. Plume-induced flow separation intensified heat on the leeward side reducing structural margins, causing the booster to rupture from stage separation induced loads.

Fortunately, the corrective actions are straight forward: increase thermal protection system thickness on Stage 1 and reduce angle of attack during key phases of the flight. Corrective actions have already been implemented.

The company expects to resume flights in the very near future, probably before the end of 2025.

Spanish rocket startup PLD completes test of prototype first stage

9:07 am

The Spanish rocket startup PLD has successfully conducted a short “burst test” of a full scale prototype of the first stage of its proposed Miura-5 rocket as it prepares for a first launch.

The test subjected the stage to pressures beyond its intended operating limits to determine the point of structural failure. According to the PLD Space update, the test validated the structural performance of the tank under cryogenic temperatures and extreme pressure conditions. The company will now proceed with a fully integrated qualification model of the stage that includes all the elements required for flight.

The company had hoped to launch the rocket for the first time from its French Guiana launchpad before the end of this year, but that schedule has slipped to 2026. At the same time, it clearly is making real progress, having also tested the engines of the rocket’s second stage in August.

The central star-forming cauldron of M82, the most well known star-forming galaxy

12:40 pm

The central star-forming region of M82
Click for original. For original of inset go here.

Cool image time! The picture to the right, cropped, reduced, and annotated to post here, was released today by the Hubble Science team. It shows the central star-forming core of the galaxy M82, only about 12 million light years away and long known as a “peculiar” galaxy by earlier research from the 20th century. For this reason I used the 1963 optical image taken by the 200-inch Hale Telescope at Palomar in California as the inset, showing the entire galaxy. At the time the data only suggested some major energetic events were occurring in the galaxy’s core, as indicated by what looked like filaments shooting out from that core at right angles to the plane of the galaxy.

Data since then, from Hubble and Webb and other space telescopes, have revealed that this galaxy, which some have nicknamed the “Cigar Galaxy”, is forming stars at a prolific rate.

Forming stars 10 times faster than the Milky Way, the Cigar Galaxy is what astronomers call a starburst galaxy. The intense starburst period that grips this galaxy has given rise to super star clusters in the galaxy’s heart. Each of these super star clusters contains hundreds of thousands of stars and is more luminous than a typical star cluster.

The red indicates the dust that permeates the galaxy. The blue comes from the radiation emitted from the clusters near the center, illuminating and ionizing that dust.

Bubbling lava frozen in a Martian crater

Bubbling lava frozen in a Martian crater
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 23, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). This one-mile-wide unnamed crater was a featured image last week by the science team. As noted in the caption, written by Chris Okubo of the U.S. Geological Survey:

This area was covered by a large flood of lava, which we see as the generally flat areas surrounding the crater. As the lava flowed across, some of it flowed into this crater through a low spot along the crater rim.

Once in the crater, the lava heated ground water or ground ice in the floor, causing the water to boil and turn into steam. This steam then exploded through the overlying lava and created small, ring-shaped formations. These are called ”rootless cones,” and they record the presence of ground water or ground ice in the crater floor at the time of the lava eruptions.

In other words, when this crater was flooded with hot lava, it was filled with ice or water. That fact is significant because of the crater’s location, as shown in the overview map below.

Progress docks safely with Zvezda module at ISS

9:24 am

ISS as of today
ISS as of today. Click for original.

In what is increasingly a worrisome procedure, Russia’s just launched Progress freighter successfully docked with the aft port of the Zvezda module at ISS this past weekend, bringing with it more than 5,000 pounds of supplies and research equipment.

The image to the right, annotated additionally by me, shows the present configuration of spacecraft at ISS. The concerns center on the stress fractures that have been found in the Zvezda hull, fractures that have caused the air leak on ISS and are believed attributable to the many dockings to the module since its launch in the late ’90s, as well as the module’s age. It was first built in the late ’80s, making it almost four decades old.

For recent dockings, NASA now closes the hatch between the Russian and American halves of the stations, just in case Zvezda experiences a catastrophic failure. The Russians seem less concerned, but nonetheless they also take extra care during dockings. It is my understanding their astronauts prepare their Soyuz capsule as a lifeboat and immediately escape during these operations.

Starlink down for about an hour last night

8:53 am

According to several major news sources, Starlink was down for about an hour last night globally, impacting several tens of thousands in the U.S. alone.

More than 37,000 US users were reporting issues with the internet service Monday at 12:30 a.m. ET, according to the website Downdetector.com. By 1:30 a.m., that number had fallen into the hundreds. The internet service owned by Musk’s SpaceX stopped working on “the entire frontline in Ukraine” around 7:30 a.m. Kyiv time (12.30 a.m. ET), said Maj. Robert “Magyar” Brovdi, the commander of Ukraine’s unmanned systems force, on Telegram. As of 8:00 a.m., service was gradually being restored, he said.

I link to CNN, but numerous other outlets thought this story significant enough to give it front page coverage. That this is considered news, however, illustrates perfectly how well Starlink functions normally. A brief outage lasting less than an hour makes the cover of every news outlet in the world, because normally Starlink works without problems for its more than six million subscribers.

SpaceX has not as yet provided any information about the cause of the outage. I suspect we are seeing the result of a hacker attack, possibly by Russia, but that is pure speculation. Even if not, it is in SpaceX’s interest to outline in detail what happened. This has been its policy in the past, but in the previous outage in July the company was not forthcoming. That lack of transparency has not served the company well.

Space station startup Vast endorses NASA’s new strategy that no longer requires a continuous human presence in space

The American space stations under construction
The American space stations under development

Officials from the space station startup Vast revealed at a conference last week that they endorse NASA’s new strategy that, not only no longer requires the commercial stations to immediately establish a continuous human presence in space, will also award multiple development contracts to the commercial stations.

Speaking Sept. 11 at the Global Aerospace Summit, Max Haot [chief executive of Vast] endorsed NASA’s new strategy, announced more than a month ago, that calls for multiple Space Act Agreements to support development leading to a four-person, 30-day demonstration mission. “We think it’s really the right direction,” he said, noting it accelerates the award timeline. NASA said in a draft solicitation this month it expects to award multiple funded agreements by April 2026, months sooner than under earlier plans.

The original plan had been to choose at most two, but likely only one of the four consortiums/companies that are developing station proposals. The winner would have gotten a big contract that would have also required it to push hard for continuous full time occupation, from day one.

The new plan will instead award smaller development contracts to as many as three of the four station projects, aimed at getting them off the ground and operating, even if astronauts only fly in them intermittently. Eventually the hope is that their capabilities will expand quickly to permanent occupation, especially if they start earning revenue from the private sector, outside NASA. In fact, the smaller government contracts will force them to seek investment and profits elsewhere.

The four commercial stations under development, ranked by me based on their present level of progress:

Italian rocket company Avio commits $469 million to expand operations

8:59 am

The Italian rocket company Avio, which owns the Vega-C rocket, today announced that is has approved a $469 million fund to expand its manufacturing capabilities, including building a production facility in the United States.

Announced on 12 September, the capital raise is part of a new ten-year business plan targeting an average annual growth rate of about 10% in turnover and more than 15% in core profit (EBITDA). This growth will be driven by a higher Vega C launch cadence, the introduction of Vega E, continued participation in the Ariane 6 programme, and the construction of a new defence production facility in the United States, which is expected to be completed by 2028.

The management of Vega-C had previously been controlled by the European Space Agency’s (ESA) commercial arm, Arianespace, which had owned and operated all of Europe’s rockets. ESA however is eliminating that commercial arm, shifting from the government-run model to the capitalism model, whereby it simply acts as a customer buying services from the private sector.

As part of that shift, Avio is in the process of taking back its Vega-C from Arianespace. Beginning next year it will be marketing the rocket directly to customers. This major investment reflects this change. The company is now free to pursue profits wherever it can find them, and it appears it wishes to market itself aggressively to American satellite companies as well as its defense industry.

Russia launches Progress to ISS

Russia today successfully launched a Progress freighter to ISS, its Soyuz-2 rocket lifting off from the Baikonur spaceport in Kazakhstan.

The freighter will dock with the aft port of the Zvezda module in two days. When it does so, expect NASA to require its astronauts to close the hatch between the American and Russia parts of ISS. The agency has real concerns about the stress fractures in Zvezda’s hull that are the cause of the station’s air leaks, and fears it could at some point fail catastrophically during a docking. The odds of this happening are small, but they are larger than they should be.

Update on what SpaceX learned about Starship’s tiles during the 10th test flight

11:27 am

Superheavy after its flight safely captured at Boca Chica
Superheavy after the October 2024 flight,
safely captured during the very first attempt

Link here. The update comes from a presentation given this week by Bill Gerstenmaier, SpaceX’s executive in charge of build and flight reliability, at the American Astronautical Society’s Glenn Space Technology Symposium in Cleveland.

Lots of new details. First, almost no tiles fell off during this flight. More significant, they found that the use of metal tiles won’t work. They tested three, and found that “The metal tiles… didn’t work so well.”

Gestenmaier also outlined how the flight provided the necessary data for sealing the gaps between the tiles better.

Gerstenmaier pointed to a patch of white near the top of Starship’s heat shield. This, he said, was caused by heat seeping between gaps in the tiles and eroding the underlying material, a thermal barrier derived from the heat shield on SpaceX’s Dragon spacecraft. Technicians also intentionally removed some tiles near Starship’s nose to test the vehicle’s response.

“It’s essentially a white material that sits on Dragon and it ablates away, and when it ablates, it creates this white residue,” Gerstenmaier said. “So, what that’s showing us is that we’re having heat essentially get into that region between the tiles, go underneath the tiles, and this ablative structure is then ablating underneath. So, we learned that we need to seal the tiles.”

They hope to do the 11th test flight in October, repeating the same suborbital configuration of previous flights, using the same version 2 of Starship. The plan will then be to follow up with a first suborbital flight of version 3 in 2026, followed quickly by orbital flights. During one of those orbital flights they will also try to do a chopstick catch of Starship. They also hope to do the first refueling tests next year.

All in all, it appears the test program is proceeding as hoped, and is about to accelerate significantly.

Croatian startup moves up the launch date for two subscale returnable capsules

9:44 am

The Croatian startup Genesis Space Flight Laboratories (Genesis SFL) has now accelerated the development of its orbital returnable capsule for manufacturing in space, moving up the launch date for its first two subscale demonstrator capsules from 2027 to 2026.

Initially planned for 2027, the missions were moved forward after Genesis SFL announced on 9 September that it had secured earlier slots with an as-yet-undisclosed launch provider.

Speaking to European Spaceflight, Genesis SFL CEO Bence Mátyás explained that the company’s GEN-1 and GEN-2 demonstrators will likely be the smallest reentry capsules ever flown, comparable in size to picosatellites. Despite their diminutive size, the capsules will be capable of remaining in orbit for approximately six months before performing reentry procedures, a capability made possible by the use of a host satellite [essentially the service module] also under development by the company. Once on a reentry trajectory, the capsule will separate from its host satellite and deploy a mini-parachute and antenna to enable recovery following a splashdown.

If these demonstrators succeed, the company plans to scale up later GEN capsules step-by-step, eventually matching and even exceeding those of companies like Varda.

The returnable capsule industry appears at the moment to be bursting with new companies. In the U.S. we have Varda, Inversion Space, Sierra Space, and even SpaceX using Starship. In Europe — in addition to Genesis in Croatia, we have The Exploration Company in France, Atmos in Germany, PLD in Spain, and Space Cargo in Luxembourg. And I am certain there are others that I am missing.

Very clearly the investment community sees big profits in using orbital capsules to manufacture products for later sale on Earth.

Rather than streamline red tape, a UK government committee proposes it should fund its space industry directly

9:28 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

In a move that will do nothing to solve the red tape that has stymied the spaceports in Scotland as well as the launch industry in the United Kingdom, a Scottish government committee has concluded that the solution is for the UK government to become a direct investor in its space industry, increasing funding to both its spaceports and any launch companies that wish to use them.

The Scottish Affairs Committee heard from a number of experts and figures involved in the space industry. Professor Malcolm Macdonald, of Strathclyde University, said the UK had not always sustained its “first-mover” advantage in the space launch sector.

The report’s conclusion stated: “It is clear that the UK is falling behind its European counterparts in terms of public investment, leaving Scottish spaceports at a competitive disadvantage in a fast-moving global market. Without sustained backing from the Government – particularly in infrastructure – Scotland risks missing a generational opportunity to lead in space launch. To fully realise this potential, the UK Government needs to go further and faster.”

The MPs called for sustained Government investment in infrastructure.

The report also noted that despite a half-decade head start in establishing its spaceports in Scotland, the Andoya spaceport in Norway is now winning the race to become Europe’s prime spaceport.

Talk about not seeing the forest for the trees. The reason the UK’s spaceports have fallen behind is because its regulatory framework is impossible to navigate, taking years to get any approvals. But rather than fix this, this committee proposes throwing taxpayer money at the problem.

My prediction: It won’t work. Outside rocket companies will continue to move away from the UK, while any that get government investment to stay will find it difficult to get business, because it will still be impossible to get launch licenses when needed.

India’s government finalizes deal to transfer operation of its SSLV rocket to a private company

9:13 am

India’s government and its various space agencies yesterday finalized its deal with the Indian company Hindustan Aeronautics Limited (HAL) to take over the manufacture and operation of its government-designed SSLV rocket (Small Satellite Launch Vehicle) for the next decade.

Under the technology transfer contract that HAL signed with ISRO, Indian National Space Promotion and Authorisation Centre (IN-SPACe) and NewSpace India Limited (NSIL), the aviation major will absorb the technology in the first two years, which will be followed by a 10-year production phase. The agreement grants HAL a non-exclusive, non-transferable license to the SSLV technology, which includes comprehensive design, manufacturing, quality control, integration, launch operations, and post-flight analysis documentation, as well as training and support. HAL will be responsible for the mass production of SSLV to meet Indian and global demands,” the company says in a statement.

Initially the Modi government had implied the transfer would involve ownership of the rocket by the private company, so that it could market the rocket for profit. The actual deal does not do this. Instead, it gives HAL the responsibility to manufacture and operate the rocket, but it appears sales and ownership will still be under the control of India’s space agency ISRO. If this is correct, the deal accomplishes less than nothing, and in fact simply adds another player in the game, making the SSLV rocket less competitive in the international market.

Then again, the Modi government might see this deal as just a first step in the transition from a government-run space program to a competitive independent space industry. It needs to wrest control from ISRO, and this can’t be done politically in one fell swoop.

To me however this deal for HAL is a bad one. It now has the responsibility for making and launching the rocket, but none of the benefits.

South Korea military begins project to develop a methane-fueled rocket engine

8:01 am

The South Korean defense department has awarded a consortium of Korean aerospace companies a contract to develop a methane-fueled engine that can be used in reusable rockets.

According to the space industry, a consortium led by Hyundai Rotem and Korean Air was selected on the 9th as the preferred negotiator for a 35-ton methane engine technology development project overseen by the Agency for Defense Development (ADD) under the Defense Acquisition Program Administration (DAPA). A formal agreement will be signed in November, initiating full-scale research and development (R&D). The project, budgeted at approximately 49.1 billion Korean won [$35 million], will run until 2030.

It appears there has been a turf war between the military and South Korea’s newly formed space agency, KASA. Originally KASA had planned to develop this engine, but apparently the military’s proposal won out. KASA now says it will collaborate with the ADD, but the project’s budget now goes to the military.

NASA inspector general: Dragonfly mission is vastly overbudget and behind schedule

According to a new NASA inspector general report issued today, NASA’s Dragonfly mission to Titan is now billions overbudget and is likely not be ready to launch in 2028.

You can download the report here [pdf]. From its executive summary:

Dragonfly was selected under a New Frontiers Announcement of Opportunity with a $850 million cost cap on Principal Investigator-Managed Mission Costs, which primarily includes development costs but excludes launch vehicle and post-launch operations costs. However, by April 2024, those costs had grown to $2.6 billion and the launch delayed by more than 2 years, from April 2026 to July 2028. The cost increase and schedule delay were largely the result of NASA directing APL to conduct four replans between June 2019 and July 2023 early in Dragonfly’s development. Justifications for these replans included the COVID-19 pandemic, supply chain issues, changes to accommodate a heavy-lift launch vehicle, projected funding challenges, and inflation.

The report now estimates the budget will eventually rise above $3 billion, cost that is eating away at NASA’s entire planetary budget, making other missions impossible. The project itself is far from ready, with multiple unfinished issues that make its present launch target of 2028 very unlikely.
