ISRO successfully tests thrusters to be used on its manned Gaganyaan capsule

9:14 am

India’s space agency ISRO last week successfully completed two tests of the attitude control thrusters that will be used on its manned Gaganyaan capsule.

In a statement issued on Wednesday, ISRO said that the short-duration tests, lasting 30 seconds and 100 seconds respectively, were aimed at validating the test article configuration. The space agency stated that the overall performance of the propulsion system during the hot tests had been normal and aligned with pre-test predictions.

It was also noted that during the 100-second test, the simultaneous operation of all Reaction Control System (RCS) thrusters in various modes—both steady state and pulsed—along with all Liquid Apogee Motor (LAM) engines had been successfully demonstrated.

The first unmanned test flight of Gaganyaan is presently targeting a launch in the last quarter of 2025, with two more unmanned test flights in 2026. The manned mission of one to three days would follow in 2027.

India transfers ownership of SSLV rocket from space agency to government-owned private aerospace company

9:55 am

Capitalism in space: As part of the Modi government’s effort to switch its space industry from something owned and run entirely by its space agency ISRO, it has now awarded the ownership and control of ISRO’s newest and smallest rocket, the SSLV, to the aerospace company Hindustan Aeronautics Limited (HAL).

The company paid about $60 million for the purchase, and the right to build, market and launch it. It hopes to build between 6 to 10 rockets per year, depending on launch demand.

This transfer is not as radical as it appears. Though HAL operates mostly as an independent aerospace company, it is still owned by the government with its board of directors appointed by the president of India. The rocket will thus still be owned and controlled by the government, not a private company.

At the same time, this deal acts to shift power away from the space agency ISRO, which I suspect is the plan: Divvy up ISRO’s assets, which will eventually make it harder for it to block independent operations by private companies. As part of that program, the government has also transferred construction of the larger PSLV rocket from ISRO to a consortium of companies.

Whether this shift can create an independent and competitive rocket industry in India is very unclear. In many ways the country’s strategy so far mimics more China’s pseudo-company approach (where the companies raise investment capital, compete for government and commercial contracts, but are always under the full control and supervision of the government) then it does America’s free enterprise system (where ownership and control resides entirely with the companies, and the government only buys the services it needs from them).

The American model is by far the most successful in encouraging innovation and competition for the least cost. The Chinese model produces some results for less cost, but relatively little innovation. Instead, it copies what Americans do.

Starlink begins or expands service in three more countries

10:07 am

Starlink this week officially began service in both India and the African country of Guinea-Bissau, while expanding its service in the Ukraine to include phone-to-satellite texting.

In India the final licensing approval came through, and the service is now available to customers through two different Indian telecommunication platforms.

The deals consists of selling Starlink’s equipment through Jio and Airtel’s retail networks, while Jio will also offer customer service, installation, and activation support. It will emphasise on providing high-speed internet to businesses, healthcare centres, schools and remote communities across India, according to reports.

SpaceX also begain to offer its services in Guinea-Bissau, a former Portuguese colony located on Africa’s northwestern coast and the seventh African country to approve Starlink. Its license had been approved in April, but the service wasn’t available apparently until now.

Finally, regulators in the Ukraine have now approved the use of Starlink’s phone-to-satellite service by the Ukrainian telecommunications company Kyivstar. The program will at present be limited to texting and emergency alerts. This expands Starlink’s already extensive internet availability there.

In every case, Starlink will act to decentralize control of communications aware from the government, as its sells terminals to ordinary citizens.

Starlink approved for India

8:35 am

After several regulatory issues that blocked the company during the past few years, SpaceX has finally gotten approval to sell Starlink to customers in India.

The company hopes to initiate service within the next year. There still remain some required license approvals:

Although the licence from the Ministry of Telecommunications clears a major hurdle, the service’s final launch in India will depend on further regulatory clearances, including the Telecom Regulatory Authority of India’s (TRAI) recommendations on spectrum allocation, which are still pending approval from the Department of Telecommunications (DoT).

These should be pro forma at this point, since it was the ministry of telecommunications that issued this most recent license. Why would it issue one permit but then block another?

Axiom’s fourth commercial passenger flight to ISS delayed another two days

9:45 am

NASA, Axiom, and SpaceX yesterday announced that the launch of Axiom’s fourth commercial passenger flight to ISS, dubbed Ax-4, has been delayed two days to June 10, 2025.

NASA, Axiom Space, and SpaceX are targeting no earlier than 8:22 a.m. EDT on Tuesday, June 10, for launch of the fourth private astronaut mission to the International Space Station, Axiom Mission 4. This shift allows teams to account for predicted inclement weather during the SpaceX Falcon 9 rocket and Dragon spacecraft transport in addition to completing final processing of the spacecraft ahead of launch.

The Dragon capsule for this mission is new, and there had been delays in getting it built. Though weather is likely the biggest reason for this delay, it also sounds as if SpaceX has needed just a little bit of extra time to finalize the capsule’s construction.

The mission will fly one Axiom astronaut plus three passengers, each a government astronaut from India, Poland, and Hungary. It will spend about a week docked at ISS.

Third stage of India’s PSLV rocket fails during launch

9:36 pm

India’s PSLV rocket today (May 18 in India) experienced a launch failure in attempting to place an Earth observation satellite into orbit, with the failure occurring during the engine firing of the rocket’s third stage.

The link is cued to just before the tracking screen began showing the third stage drop from its planned trajectory. The suddenness of the loss of data as well as the drop in the trajectory suggests the engine exploded during firing, but that is pure speculation. Regardless, the launch, only the second India has attempted in 2025, was a failure.

Moreover, the first launch this year was a failure also, though the GSLV rocket in that launch performed as expected and deployed the satellite in its planned transfer orbit. At that point however the Indian-built satellite’s thrusters failed to operate, stranding the satellite in the wrong orbit , which soon decayed. UPDATE: According to a more recent report, it has remained in orbit but provides little service.

Thus 2025, which ISRO had predicted to be India’s most active year ever, is so far not turning out so well. ISRO hopes to begin launching its first unmanned test flights of its Gaganyaan capsule later this year, using its Heavy Lift Vehicle Mark 3 rocket (HLV-M3), an upgraded version of its GSLV rocket. One wonders if these issues will impact that schedule.

These failures by the space agency could however help the Modi government shift the balance of power away from ISRO and to its emerging private rocket sector. If the agency can’t get it done, maybe the private sector should be given the chance to do it. For example, the government has been pushing to have the ownership and management of the PSLV rocket transferred from ISRO to a private rocket company since in 2016. In the nine year since, there however has been little sign of this shift happening.

Part of the problem has been that none of India’s private rocket startups are really ready to take over these operations. The transfer is further made less likely by the strong resistance to change within ISRO’s bureaucracy. These failures provide political ammunition to push back against that resistance.

Europe and India sign agreement to work together on manned space flight

9:35 am

The European Space Agency (ESA) yesterday announced that it has signed an agreement with the Indian government that will lay the groundwork for them to work together on manned space exploration, first in connection with their future space station plans and later on lunar exploration.

ESA and ISRO declared their intent to work together on the interoperability of rendezvous and docking systems to allow their respective spacecraft to work together in low Earth orbit. They will also examine further activities related to astronaut training, analogue space missions – where teams test aspects of space missions in ground-based simulations – and parabolic flight activities.

…Future cooperation possibilities include ESA astronaut flight opportunities to the planned Bharatiya Antariksh Station (BAS) and early scientific utilisation, as well as developing infrastructure in low Earth orbit. The two space agencies are also discussing alignment on payloads and robotic scientific missions to the Moon.

Faced with the decommissioning of ISS in 2030, as well as the likely end to several major Artemis components (Orion and Lunar Gateway) that ESA has had a major part, it appears Europe has quickly begun looking for other alternatives. It already has partnered with the American consortium building the Starlab space station, but this new agreement with India gives it more options.

India meanwhile gets aid and support from Europe. It could even be that both are negotiating transferring some of Europe’s Lunar Gateway modules to India’s space station.

SpaceX gets approval to sell Starlink in India

9:18 am

Almost immediately after India’s government issued this week new tightened regulations for allowing private satellite constellations to sell their services in India, it also apparently completed negotiations with SpaceX to allow it to sell Starlink in India based on these rules.

According to sources, the DoT [Department of Transportation] granted the LoI [Letter of Intent] after Starlink accepted 29 strict security conditions, including requirements for real-time terminal tracking, mandatory local data processing, legal interception capabilities, and localisation of at least 20% of its ground segment infrastructure within the first few years of operation.

Starlink’s nod came amid heightened national security sensitivities, coinciding with India’s pre-dawn Operation Sindoor strikes on terror camps across the border in response to the Pahalgam massacre. However, DoT officials clarified that the decision to approve Starlink was independent of these military developments.

At the moment SpaceX’s chief competitors, OneWeb and Amazon’s Kuiper constellation, have not yet obtained the same permissions. This allows SpaceX to grab a large portion of the market share in India before either of these other companies.

India tightens its satellite regulations for foreign companies

9:27 am

In what is a likely response to the increased military conflict with Pakistan, India’s government has announced new satellite regulations for foreign companies that will likely impact the operations of both Starlink and OneWeb.

The country’s Department of Telecommunications (DoT) announced 29 additional regulations May 5, citing national security interests, which also apply to companies that already hold licenses for providing space-based communication services directly to users.

The rules include a requirement for call logs and other user data to be stored in India, and new obligations for interception and monitoring under national law. Satellite operators must also show how they plan to source at least 20% of their ground infrastructure equipment from India within five years of commercial launch.

The article at the link suggests that these new regulations will have a greater impact on OneWeb than Starlink. Yet, OneWeb already has approval to sell its services in India, while Starlink has not.

The article also included one interesting tidbit from a Starlink official, noting that the company expects to have 6.5 million subscribers by the end of this year. Based on the company’s subscriber fees, that translates into many billions in revenue. Very clearly SpaceX no longer needs NASA to develop Starship.

Update on launch schedule for India’s manned space program

10:59 am

According to the head of India’s space agency ISRO, V Narayanan, the first unmanned Gaganyaan orbital mission is now targeting a launch in the last quarter of this year, followed by two more unmanned test flights in 2026 and the manned mission of one to three days flying in the first quarter of 2027.

This schedule appears more firm than any previously announced. When first proposed back in 2018, ISRO’s goal was to launch the first manned mission in 2022. And like all government projects, the launch date kept getting pushed back again and again. ISRO officials will blame the COVID panic for these delays, but that’s hogwash. While ISRO shut down for almost two years out of fear of a only slightly more potent illness than the flu, others did not, and ended up stealing almost all of ISRO’s commercial business as a result.

The delays in Gaganyaan also stem from the unrealistic goals first put forth by ISRO. For example, initially the program did not include these unmanned test flights, a lack that was foolish and later corrected.

Based on all reports in the past year, however, it appears that this newest schedule probably reflects reality, and will take place more or less as described.

India’s Spadex mission completes second autonomous docking

9:06 am

According to one government official, India’s space agency ISRO has now successfully completed a second autonomous docking in orbit using the target and chase spacecraft of its Spadex mission, launched in December 2024.

Between the undocking on March 13 and the second docking operation, Isro had carried out a “rolling” or “rotating” experiment — in late March. … At the time, Narayanan [ISRO chairman], while confirming the success of the operation, had said that more experiments were in store. … “…The satellites have a lot of propellant… I have only told [the teams] one thing, please do everything [on] simulation on ground [first]. Let us be very careful. Let us not make any mistakes as a wealth of data can be generated [through various experiments].”

The rolling experiment, which was likened to the Chandrayaan-3 “hop” experiment the space agency conducted on Moon in terms of learning it provides for future missions, helped Isro validate multiple softwares, ground station control and more.

This second docking further confirms the technology and the ability of ISRO’s engineers to perform it. Originally the plan had been to do only one docking. The two spacecraft were to then undock and go their separate ways, doing other orbital research. Narayanan changed that plan, since this technology is essential for India’s planned space station. The focus is now on multiple test dockings, in a variety of configurations, with more to come.

Two different states in India announce space policies

11:15 am

Map of India

Capitalism in space: In another indication that India’s governments are going full bore for private enterprise in space, two different Indian states this week announced new space policies designed to attract private investment and space startups.

Those two states, Tamil Nadu and Gujarat, are shown on the map to the right. Tamil Nadu announced its new space industrial policy hopes to attract more than a billion dollars in space companies to the state. Gujaret in turn announced its own space policy aimed at attracting $5 billion in investment and 25,000 jobs over the next five years.

It is not surprising that Tamil Nadu has issued this policy, considering that it is the state where India’s new second spaceport, Kulasekarapattinam, is located, and is being built as a launch site for commerical operations. Gujaret is at first glance less obvious, but it houses a major facility of India’s space agency ISRO. It is also one of India’s most industrialized states.

Both however illustrate the impact of the Modi government because of its policy to encourage private enterprise and de-emphasize government control. Not only is the federal government pushing capitalism, the country’s individual states are joining in.
