Skyroot announces launch window for 1st launch of Vikram-1 rocket

India’s rocket startup Skyroot yesterday announced that its first Vikram-1 rocket is stacked on the launchpad and the company now has a launch window from July 12 through August 4, 2026.

It will attempt to reach a 450 kilometer orbit at a 60 degree inclination. The launch is mostly to test the rocket’s systems, including its guidance and navigation as well as its ability to complete a stage separation and ignition of its second stage. The company says it will also carry several small commercial payloads from both Indian and international customers, but it did not name them.

Few new rockets succeed on their first launch attempt, but it does happen. For India this launch and company are the equivalent of SpaceX in the U.S. in 2006. At that time NASA ran everything. The big space rocket companies (Boeing and Lockheed Martin) had no interest in innovation or competition, and in fact had formed a partnership holding a monopoly on all military launches, while acting almost like the rocket division for those government agencies.

In India now, its space agency ISRO runs everything, including building and flying the nation’s rockets. The Modi government has been trying to get the agency to transfer ownership and management of those rockets to private companies, but the results have been inconclusive. ISRO has transferred some operations and management to private companies for two of its rockets, but done so in a way that ownership and control still remains with the agency.

A success by Skyroot would for the first time create a real alternative to the government agency. But like SpaceX in 2006, the full transition to a private space industry will likely take an additional decade or more. But a success now would be a start.

First unmanned test of India’s manned Gaganyaan capsule possibly delayed until late ’27

9:11 am

In a presentation yesterday, the head of India’s space agency ISRO V Narayanan indicated that the first unmanned test flight of its manned Gaganyaan capsule might be delayed until the third quarter of 2027.

That test flight was originally targeting a March 2026 launch — part of a series of three unmanned test flights before the manned flight in early 2027 — but March came and went and nothing happened, nor did ISRO explain the lack of any action.

In indicating the possible delay, Narayanan also noted that the agency was looking at a launch before the end of this year. A delay until late ’27 — more than a year — however would suggest a significant issue. It would also mean the manned flight could not occur until 2028, at the earliest.

When Gaganyaan was first proposed in 2018, the goal was to have the first orbital flight in 2022. Since then the program has experienced endless delays and postponements. This new announcement, with no explanation, fits ISRO’s recent pattern of secrecy. No specific reasons for this year’s delays have ever been offered. Meanwhile, the agency has refused to outline for more than two years the specific causes of the two PSLV rocket failures of its third stage, both of which occurred at almost the exact same time in launch.

The secrecy suggests a cultural problem at ISRO, even more serious than a technical one. It implies an unwillingness to deal with error, thus resulting in repeated failures.

India won’t reveal the cause of its two PSLV rocket failures

Though one of India’s high government officials yesterday announced that its space agency ISRO had “resolved” the third stage issue that caused two consecutive failures of its PSLV rocket, that official also refused to provide any details.

Union Minister of State for Science and Technology Jitendra Singh on Saturday said that the anomaly in the Polar Satellite Launch Vehicle (PSLV) has been resolved. Dr. Singh said on the sidelines of the Research, Industry, Start-up and Entrepreneurship (RISE) Conclave 2026 in Bengaluru, that the national level expert committee constituted to review the reason for anomaly in PSLV Vehicle has submitted its report and the anomaly has been detected.

“The report has come out and the anomaly has been detected. However we cannot share that (reason for the anomaly) on a public platform. But experts are working on it, which has been resolved and very soon we will be back on the track,” Dr. Singh said replying to a query by The Hindu.

Note that after the first third stage failure in 2025, ISRO was also reticent about revealing the problem and how it fixed it. Then the third stage failed again at almost the exact same moment during the next launch in January 2026.

A month later this same official announced ISRO knew what the problem was and had fixed it — once again giving no details — and said the next launch was scheduled for June 2026. It is now June, and despite Singh’s promise no PSLV launch is being prepared.

This lack of transparancy speaks very badly for ISRO. It will make it extremely difficult for it to attract any commercial customers. In fact, that is basically what has happened. Before the Covid panic ISRO had a decent share of the commercial satellite market. Now, even with that satellite market growing in leaps and bounds, it has almost no commercial customers.

India takes first step to privatize its largest rocket, the LVM3 or Bahubali

9:21 am

LVM3 launching a set of OneWeb satellites in 2022
LVM3 about to launch a set of OneWeb satellites in 2022

IN-SPACe, the agency assigned the job for shifting India’s space effort away from its space agency ISRO and to the private sector, yesterday released an Expression of Interest (EOI), asking India’s private aerospace industry for bids to take over operations of ISRO’s LVM3 rocket (also called Bahubali), its most powerful rocket that ISRO plans to use for its future manned and interplanetary missions.

The invitation for EOI, released on Tuesday, invites eligible Indian private companies or industry consortia to acquire and operationalise LVM3 technology from ISRO. The LVM3, often referred to as ISRO’s ‘Baahubali’ rocket, is the agency’s heaviest operational launch vehicle and is behind key missions including Chandrayaan 2 and 3. The selected private entity will receive technology transfer and extensive support from ISRO to absorb the technology and begin manufacturing and launching LVM3 vehicles commercially.

The EOI invitation also lays down the eligibility criteria for the applicable private entities. ISRO’s handholding and infrastructure support is proposed for a defined period of 42 months or until the realisation and launch of two LVM3 vehicles by the selected entity, whichever comes earlier.

The eventual goal is for the private sector to market LVM3 for commercial purposes, outside of ISRO’s Gaganyaan and space station manned program. While ISRO will continue to operate the rocket to launch manned missions as well as the country’s proposed Bharatiya Antariksh Space Station (BAS), the private company that takes over LVM3 will sell it to the international market for profit. As this is a powerful rocket, it can compete directly with SpaceX’s Falcon 9, ULA’s Vulcan, Blue Origin’s New Glenn, and Arianespace’s Ariane-6.

IN-SPACe has already begun this process with ISRO’s smallsat SSLV rocket, transferring operations in June 2025 to Hindustan Aeronautics Limited (HAL). There are also indications it is trying to do the same with ISRO’s mid-sized PSLV rocket. If all three transfers go through, almost all of ISRO’s rockets will be operated by the private sector.

Don’t expect this transition to the private sector to happen quickly. As we have seen in the U.S., the shift away from a government-run space program to a chaotic free capitalist space industry can take many years, decades even. And its eventual success is never guaranteed, as government agencies fight hard to protect their turf, and they have the power of government coercion to back them up.

New study using Chandrayaan-2 data again suggests ice in crater near Moon’s south pole

9:06 am

The Moon's south pole region

The uncertainty of science: A new study by scientists in India using data from the Indian lunar orbiter Chandrayaan-2 has once again found evidence strongly suggesting the existence of water ice in several permanently shadowed craters near Moon’s south pole.

The findings are based on observations made by the Chandrayaan-2 orbiter’s Dual Frequency Synthetic Aperture Radar (DFSAR), a sophisticated microwave imaging instrument capable of probing beneath the lunar surface.

Among the craters examined, scientists found particularly strong evidence of subsurface ice in a 1.1-kilometre-wide crater located within the larger Faustini crater near the Moon’s south pole. Researchers said the crater displayed a distinctive “lobate-rim morphology”- a flow-like structural pattern that may indicate the impact event penetrated an ice-rich subsurface layer.

On the map above the green dot to the right of the south pole marks the location of the small crater inside Faustini Crater. Their conclusions were based first on microwave data suggesting subsurface ice, and second on the lobate shape of this crater’s rim, which has a kind blobby look implying the material is muddy and impregnated with ice.

Increasingly the data from all sources seems to suggest that if there is ice in these permanently shadowed craters, it is likely impregnated in the soil, and will require processing to extract.

The present state of India’s space program

India’s space agency ISRO yesterday released its annual report [pdf], outlining its accomplishments over during 2025.

Like all such reports, it is filled with glowing superlatives. It provides little concrete information about the agency’s more serious issues, such as what it is doing to fix the upper stage of its PSLV rocket, which has failed on the last two consecutive launches. All the annual report says on this subject is the following:

Based on the recommendations of the National Level Committee comprising of eminent experts from academia & industry, the third stage of PSLV i.e., HPS3 motor with modified design was realised and two static tests were successfully completed on October 06, 2025 and November 19, 2025 as in flight, from SDSC, SHAR. The overall performance of the motor and subsystems were as expected and closer to nominal performance.

The problem is that these fixes and tests did not work. The second failure of the upper stage occurred in January 2026, less than two months later. The annual report should have noted this fact, but did not.

As for India’s planetary program, digging out the present schedule from the report is difficult. Based on this review of the annual report, the dates are as follows:

  • Chandrayaan 4 lunar sample return mission: October 2027.
  • Venus Orbiter: March 2028.
  • Chandrayaan 5 /LUPEX lunar lander: September 2028.
  • Mars Lander: No target launch date as yet.

Expect these dates to be delayed.

The report also gives a detailed description on India’s Gaganyaan manned program, but little information about the planned unmanned tests that were planned for this year, leading to a manned orbital mission next year. At the moment the schedule appears to be experiencing delays, caused mostly by the PSLV launch failures. It appears ISRO wants this issue resolved before it launches that first unmanned Gaganyaan test flight.

If you want to get an overview of India’s government space program, this annual report is a good place to start. It will at least provide a baseline on which you can build a deeper knowledge.

India’s space agency: In ’25 it did 20 maneuvers to avoid collisions in space

10:29 am

India's space agency ISRO, as transparent as mud
India’s space agency ISRO.

India’s space agency ISRO today released its annual Space Situational Report, describing the collision possibilities that now exist due to the large increase in orbiting objects. According to this report, in 2025 ISRO did 20 maneuvers to avoid collisions in space.

More than 150,000 alerts issued by the Combined Space Operations Center (CSpOC) of USSPACECOM for ISRO’s Earth orbiting satellites were analysed using more accurate orbital data from operational flight dynamics. There were 4 collision avoidance maneuvers (CAM) for GEO [geosynchronous orbits], while 14 CAMs, including one for NISAR [A NASA/ISRO radar telescope], which is designated as Risk Mitigation Maneuver in NASA terminology, were performed for LEO [low Earth orbiting] satellites. Wherever feasible, collision avoidance requirements were met by adjusting orbit maintenance maneuvers to avoid exclusive CAMs.

In addition, ISRO had to twice shift the orbit of its Chandayaan-2 lunar orbiter because of an orbital conflict with NASA’s Lunar Reconnaissance Orbiter (LRO).

The report has a lot more interesting details, as ISRO is also trying to increase its ability to track everything in orbit, rather than rely on data from the American military or American commercial tracking companies, which has been the policy in the past.

A review of India’s government space program suggests it is behind schedule

11:28 am

India's space agency ISRO, as transparent as mud
India’s space agency ISRO.

Link here. The main take-away of the article is that the investigation into the two launch failures of ISRO’s PSLV rocket has stalled everything, including the planned two unmanned orbital test missions of its Gaganyaan capsule, needed before the actual manned mission can fly in early 2027. The first was originally supposed to fly in March, but has been delayed pending completion of the investigation of the PSLV failures.

That investigation however has stalled far more than just Gaganyaan:

The Indian Space Research Organisation (Isro), which had announced an aggressive manifest of 18 launches for 2026, has so far completed only one in the first four months of the year, and that mission [PSLV] ended in failure.

The article also notes a decline in ISRO’S transparency in recent months, a decline that bodes ill for the agency and its programs. I have noted this as well. When ISRO in February 2026 announced the next PSLV launch for this coming June, it released no information from its investigation of the previous two launch failures. If ISRO knows what went wrong, it wasn’t saying. All it has told us so far is that the cause of the two launch failures was for different reasons.

India conducts another parachute drop test for its Gaganyaan manned capsule

9:03 am

Gaganyaan drop test
Click to watch video of drop test.

India’s space agency ISRO today successfully completed its second helicopter drop test of a dummy capsule, testing the parachute release system that its Gaganyaan manned capsule will use on return to Earth.

In this test, a simulated Crew Module, weighing about 5.7 tonnes, that is equivalent to the mass of the Crew Module in the first uncrewed Gaganyaan mission (G1), was lifted by an Indian Air Force Chinook helicopter to an altitude of about 3km and released over a designated drop zone in sea, near to Sriharikota coast.

Ten parachutes of four types were deployed in a precise sequence during the descent of the Crew Module, gradually reducing the velocity for safe touchdown. Subsequently, the simulated Crew Module was successfully recovered in coordination with Indian Navy. The IADT-02 test validated the parachute-based deceleration systems in the Crew Module.

The manned mission is presently scheduled for early next year, after a series of unmanned orbital test flights are completed in ’26. This schedule is significantly later than ISRO’s original schedule. When the program was first proposed in 2018, ISRO said the manned mission would happen in 2022.

India’s space agency requests proposals for building landing legs for its next new rocket

8:59 am

India’s space agency ISRO has issued a request for bids from the country’s commercial aerospace sector to build landing legs for its next new rocket, dubbed the Next Generation Launch Vehicle (NGLV).

The tender, titled “Fabrication of Landing Leg Hardware with materials for Advanced Development Module for In-situ Reusable Technologies (Admire) VTVL (10 units)”, seeks industry participation in developing critical components for a vertical take-off, vertical landing (VTVL) test vehicle under the ADMIRE programme.

…According to ISRO’s tender documents, the selected vendor will be responsible for end-to-end development, including procurement of raw materials, manufacturing, quality control planning, and final delivery of landing leg hardware. The project has been structured into three distinct phases spanning approximately 12 months.

The NGLV rocket was first approved by the India government in September 2024. Since then ISRO has completed the preliminary design of its methane engine, but has also revised the rocket’s design twice, in October 2024 and again in November 2025. This new landing leg contract suggests the agency hopes to do some test hops of a first stage prototype a year from now.

India’s second spaceport to be completed next year

The existing and proposed spaceports in India

According to officials in India, the nation’s second spaceport at Kulasekarapattinam is on schedule to be completed by next year, when it will become available for polar launches of the SSLV rocket as well as other commercial rocket launches.

India is moving ahead with plans to operationalise a new launch facility at Kulasekarapattinam in Tamil Nadu. It is expected to be commissioned during the 2026–27 financial year, according to information shared in the Lok Sabha by Jitendra Singh.

The new facility, officially called the Small Satellite Launch Vehicle (SSLV) Launch Complex, is being developed as the country’s second space launch site. The Kulasekarapattinam complex will primarily handle launches of SSLV missions to Sun-synchronous Polar Orbit, a trajectory widely used for Earth observation satellites.

The SSLV rocket is at present controlled by India’s space agency ISRO, though there has been an effort by the Modi government to transfer it to the private sector. It is not clear whether that effort has been successful. ISRO and India’s large space bureaucracy has been resistant. There have also been indications that this new spaceport will be made available to the handful of Indian rocket startups that are developing their own rockets.

The Sriharikota spaceport is ISRO’s main launch site. The Hope Island site is a proposed commercial and private spaceport, whose future remains very uncertain.

India negotiating a possible Gaganyaan docking at ISS

The head of India’s space agency ISRO, it is negotiating with NASA about doing a variety of manned space operations in conjunction with NASA, including a possible Gaganyaan docking to ISS.

According to a presentation by Isro chairman V Narayanan reviewed by TOI [Times of India], the future cooperation areas span three key areas of collaboration between the two nations’ space agencies.

The first involves comprehensive training of ISRO personnel, including astronauts, at NASA facilities across multiple domains, including robotics systems, extravehicular activity (EVA), extravehicular mobility unit (EMU) systems, resource management, space medicine and spaceflight operations, LEO and lunar mission control operations, rendezvous and docking procedures, and payload and science operations.

An important initiative outlined is the uncrewed docking demonstration of India’s Gaganyaan Orbital Module with the US Orbital Segment of the ISS — this would mark a significant technological milestone for India’s human spaceflight programme.

The third area focuses on cooperation in docking, berthing, and inter-operability systems.

It is clear ISRO wishes to get training from NASA for its manned missions. It also makes sense for it to make sure its Gaganyaan’s docking systems are compatible with ISS, Dragon, Starliner, Soyuz, and even China’s station.

Doing a test unmanned docking at ISS would also provide ISRO valuable experience in preparation for its own Bharatiya Antariksh Station (BAS). Its first module is presently scheduled for launch in 2028, with the entire station assembled by 2035.

None of this however has been finalized. If India were to do a docking at ISS, it would like have to wait until 2029, after the two tourist missions assigned to Axiom and Vast. ISS has a limited number of available ports, and I suspect a port really won’t be available until after those missions.

First unmanned Gaganyaan mission facing delay

9:33 am

Though this is not yet confirmed, sources inside India’s space agency ISRO are saying that the first unmanned Gaganyaan orbital test mission, presently targeting a March launch, is likely to be delayed in order to do additional safety checks, following the two consecutive launch failures of the agency’s PSLV rocket.

After the dual PSLV setbacks, there is zero appetite for risk at Isro. Every component, fitting, system, and subsystem of Gaganyaan is being re-examined in minute detail to ensure mission success.

The PSLV, traditionally regarded as Isro’s workhorse launcher, suffered rare back-to-back failures over the past two years, prompting a comprehensive review of quality assurance and mission readiness protocols across launch vehicles. While Gaganyaan is slated to fly aboard the Human-Rated Launch Vehicle Mark-3 (HLVM3), an upgraded version of the GSLV Mk-III, the recent setbacks have cast a shadow over the broader launch ecosystem.

The actual manned mission is presently scheduled for early next year, after a series of unmanned orbital test flights are completed in ’26. This schedule is significantly later than ISRO’s original schedule. When the program was first proposed in 2018, ISRO said the manned mission would happen in 2022.

Fairing from India’s Bahubali rocket launched in December found in Maldives

9:00 am

A man fishing off an uninhabited island in the Maldives discovered what appears to be pieces from the fairing used by India’s LVM3 rocket, also dubbed Bahubali, when it launched AST SpaceMobile’s sixth Bluebird satellite in December.

A similar discovery was made on December 28, 2025 in Sri Lanka. In both cases it is theorized that the material came from the fairings of the December Bahubali launch.

I am unable to determine the flight path of the Bluebird launch, but the location of this debris suggests it headed strongly south from India’s east coast spaceport. The fairing pieces then drifted south and west to reach the Maldives after two months.

SpaceX routinely recovers its fairing and resuses them, which due to the fairing’s basic shape has turned out to be relatively straightforward. They have the shape of a boat’s hull, and after parachuting softly down can simply float on the surface until they can be picked up. It is absurd no one else does this.

FAKE Chandrayaan-2 images of the Apollo 11 and 12 landing sites

Chandrayaan-2 images of Apollo 11 and Apollo 12 landing sites

The pictures to the right are fake, as are the two stories I had linked to in the now crossed-out post below. Both stories included pictures of the Apollo 11 and Apollo 12 landing sites that were fake and did not match the actual pictures taken earlier by Lunar Reconnaissance Orbiter.

I seem to remember that Chandrayaan-2 had taken pictures of these Apollo landing sites, but I have not been able to find those originals. Either way, the stories below as well as the pictures to the right are fake, and for that reason I have deleted the links to both.

For reasons I don’t understand, two different news outlets in the past two days decided to highlight the 2021 images taken by India’s Chandrayaan-2 lunar orbiter of the Apollo 11 and 12 landing sites, with both outlets claiming these pictures provided third-party verification that those manned lunar landings actually happened.

Those pictures are to the right. They aren’t new, but they are so good I decided they were cool enough to post again.

As for proving the lunar landing happened, that is pure anti-American silliness, sadly too often pushed by ignorant Americans. They should be ashamed. The Apollo landings were possibly the greatest single achievement Americans have ever accomplished. And if not the greatest, the landings rank near the top, and above all they certainly were among our noblest achievement.

India picks landing site for its Chandrayaan-4 lunar sample return mission

10:22 am

Landing sites at the Moon's South Pole

Scientists at India’s space agency ISRO have now picked [pdf] a preliminary landing site for its planned Chandrayaan-4 lunar sample return mission, scheduled to launch in 2028.

[Four] sites of Mons Mouton area was fully characterised with respect to terrain characteristics using high resolution OHRC multiview image datasets and it was found that 1km x 1km area around MM-4 (-84.289, 32.808) contains the less hazard percentage, mean slope of 5°, Mean height of 5334m and most number of hazard free grids of size 24m x 24m. Hence MM-4 can be considered for the potential site of Chandrayaan-4 mission.

The study area of all four sites is indicated on the map to the right by the red dot labeled “Chandrayaan-4”. This mountain, Mons Mouton, is essentially a flat plateau between the numerous craters in the south pole region (many with permanently shadowed craters). Intuitive Machines second lander, Athena, attempted a landing there last year, and tipped over, as did that company’s first lander, Odysseus, both indicated in green. Astrobotic’s Griffin lander (yellow) is targeting this mountain also, hopefully to launch later this year.

India schedules next PSLV launch for June, claims it knows cause of January launch failure

9:10 am

India's space agency ISRO, as transparent as mud
India’s space agency ISRO,
as transparent as mud

According to a statement by a government minister yesterday, India’s space agency ISRO now knows what caused the January launch failure of its PSLV rocket, and has thus scheduled its next launch for June 2026.

This had been the second PSLV launch failure in a row, both of which occurred with the rocket’s third stage at almost the exact same time. With the first failure, ISRO never outlined publicly the cause, though it claimed it had solved the issue. According to the minister’s statement, the failure of the second launch was unrelated to the first.

The minister also said that the two PSLV missions that had failed—PSLV-C61 in May 2025 and PSLV-C62 in January this year—were unrelated. “It wasn’t the same problem. When the first mission failed, there was a detailed assessment, and the problem was fixed. Both the issues were different,” Singh said.

He also added that separate internal and external failure assessment committees have been set up to analyse what went wrong in each of the missions.

No word however as to the cause of the failure has yet been released. Though he also claimed the PSLV has not lost its customers due to these issues, ISRO’s lack of transparency says otherwise. If it claims the two failures came from different causes, it should provide the details in order to reassure potential customers.

New spaceport proposed in India independent of its space agency ISRO

The existing and proposed spaceports in India
The existing and proposed spaceports in India

According to the chief minister of the Andhra Pradesh province of India, his government is presently in discussions with the private Indian energy company Greenko Group about establishing a partnership to build a commercial spaceport at Hope Island off the coast near the city of Kakinada.

Addressing the gathering of foreign investors in renewable energies and officials of the State government after performing ‘bhumi puja’ [ground-breaking] for the Green Hydrogen and Green Ammonia Production Complex in Kakinada, Mr. Naidu said, “Soon, we (Andhra Pradesh) will launch satellites from the Hope Island. It will come soon, and Kakinada will have a lot of advantages in the field of technology and innovation.”

“The Greenko Group is evincing interest in being a part of the State government’s Space City project that includes developing satellite launching facility. In a recent interaction, Greenko Founder and Group CEO Anil Kumar Chalamalsetty has shown interest in the Space City project on the Hope Island,” said Mr. Naidu.

The location has advantages over the Sriharikota spaceport, run by India’s space agency ISRO, which on polar orbital launches needs to use extra fuel to avoid flying over Sri Lanka to the south. This issue is one of the reasons ISRO is presently building that second spaceport to the south for its SSLV rocket.

If privately run, this new spaceport will have other advantages. It will possibly attract some of India’s new rocket startups, who will avoid some of the bureaucracy that accompanies any dealings with ISRO. ISRO launches always involve a gigantic number of government personnel, a cost these startups can’t afford. This new Hope Island spaceport might avoid these costs with low overhead and efficient operations.

Nothing is firm yet. From the statement above, it appears the negotiation is in a very preliminary stage, and might never bear fruit.

Indian startup raises seed money to build robotic satellite servicing “jetpacks”

9:22 am

An Indian startup, Aule Space, has now raised $2 million in seed money to begin development of a robot servicing spacecraft it intends to call “jetpacks”, designed to attach to satellites and provide them fuel and power.

The seed funding will allow Aule Space to being work on a demonstration mission planned for launch next year to test its docking capabilities. That will involve two satellites, each weighing about 30 kilograms, but Panchal said one option is to instead use an orbital transfer vehicle as the client for the docking demonstration.

The 11-person company, which plans to grow to 20 people by the end of the quarter, is working on ground tests of its rendezvous and docking technology. It has access to facilities used by the Indian space agency ISRO for testing SPADEX, a docking demonstration mission flown a year ago.

This “jetpack” concept is very similar to Northrop Grumman’s Mission Extension Vehicles (MEV), several of which have already flown and extended the life of several satellites.

Aule is exactly the type of Indian satellite startup that India’s rocket startups, Agnikul and Skyroot, are being built to serve. The problem is that all of these startups, both satellite and rocket, are literally all startups. None has flown. India’s private space sector won’t really take off until its private rocket companies get off the ground, as its government space agency, ISRO, has done a very poor job launching its PSLV and SSLV rockets (both designed for smallsats). The PSLV has failed on its last two launches, and the SSLV has been in limbo now for years.

A small European prototype re-entry capsule survived PSLV launch failure

9:24 am

A small prototype re-entry demonstration capsule, built by the Spanish startup Orbital Paradigm and dubbed the Kestrel Initial Demonstrator (KID), apparently survived for a short period the failure of the third stage of India’s PSLV rocket early this week.

According to an Orbital Paradigm press release, the survival of its little demonstrator came as a surprise. “When we understood that the launch was non-nominal it was a bit of a hit for us,” explained Orbital Paradigm CEO Francesco Cacciatore. … “I think the launch livestream was still ongoing when the team saw that we had 190 seconds of flight data transmitted and received. We needed a few minutes to realize it was real data and not a glitch.”

…“KID was tested beyond its design envelope, and it worked. Separation, power-on, and data transmission, even after reentry, all performed well despite degraded conditions,” explained the company in a 13 January update. “Based on initial analysis, it seems that we achieved 4 out of 5 launch milestones, albeit through an off-nominal profile. The failure to deliver customers’ data prevents us from declaring the mission a success.”

The company considers the mission a failure because it did not get the re-entry data back that it really needed. It says however it is moving forward on a more advanced demonstrator it hopes to launch in 2027. I suspect it will not hire India’s space agency ISRO to launch it.
