India to do 19 launches through March 2025

9:41 am

India's planned launches through March 2025

According to India’s space bureaucracy IN-SPACe, that nation has planned as many as 19 launches through March 2025.

The image to the right shows the manifest that IN-SPACe released. That agency is tasked with encouraging India’s private and independnt space industry, and it claims that 30 missions in total are planned, with half by commercial companies. This number however includes payloads and suborbital test missions, not just orbital launches. Based on the manifest to the right it appears that 19 of these missions are launches, with six being entirely private launches. One of those private launches, the first of Agnikul’s commercial Agnibaan rocket, will be suborbital.

It thus appears that in 2024 India hopes to complete 14 orbital launches. If so, this would double that nation’s previous record of seven launches in a single year. This schedule is very aspirational, with those six entirely commercial launches likely not all happening as planned.

India completes first launch of 2024

8:50 am

India’s space agency ISRO early today completed the first launch of 2024, its PSLV rocket placing an X-ray telescope into orbit along with ten payloads on its fourth stage, which is functioning as an orbital tug. Most appear [pdf] to be experiments that will remain on board, but one is an amateur radio smallsat that might be released.

As this is the only launch so far in 2024, India leads the race. It will certainly not remain the leader.

My annual global launch report for 2023 will be published tomorrow, after the holiday.

India successfully launches its first solar observation satellite

11:44 pm

India’s space agency ISRO tonight (September 2, 2023 in India) successfully used its PSLV rocket with six strap-on boosters to place in orbit its first solar observation satellite, Aditya-L1, lifting off from its coastal Sriharikota spaceport.

The spacecraft will eventually maneuver itself to the L1 point about one million miles closer to the Sun, where it will make continuous observations of the star’s visible hemisphere, using seven different instruments. Its observations will supplement those of the SOHO solar observatory (also located at the L1 point), which was launched in 1995 and is long overdue for replacement, or at least some redundancy.

For India, this was the seventh launch in 2023, which ties its previous annual launch high achieved in both 2016 and 2018. The country however has three more launches tentatively scheduled for this year, though none has as yet a specific launch date.

The leaders in the 2023 launch race:

60 SpaceX
38 China
12 Russia
7 Rocket Lab
7 India

In the national rankings, American private enterprise still leads China in successful launches 69 to 38. It also leads the entire world combined, 69 to 62, while SpaceX by itself now trails the rest of the world (excluding American companies) 60 to 62. SpaceX however has launches scheduled for September 2nd and 3rd, so these numbers are likely to change.

India officials confirm Australian beach debris comes from an old PSLV rocket

9:12 am

Officials from India’s space agency ISRO have confirmed that the large metal cylinder that washed up on an Australian beach on July 16th came from an old PSLV rocket, which which one remains at present unknown.

“We have concluded the object located on a beach near Jurien Bay in Western Australia is most likely debris from an expended third-stage of a Polar Satellite Launch Vehicle (PSLV). The PSLV is a medium-lift launch vehicle operated by ISRO,” the space agency tweeted.

A day after the object surfaced on July 16, the ISRO had confirmed to HT that the object was a part of PSLV upper stage but an old one. ISRO chairman S Somanath had said, “This is a part of PSLV upper stage but an old one. It is not from a recent mission, it must be older.” PSLV’s third stage is a solid rocket motor that provides upper stages high thrust after the atmospheric phase of launch.

If this came from an upper stage, it means it survived re-entry far better than expected, and then survived floating the the ocean for a long period. Since it does not appear as yet that the agency has determined which launch the object came from, we do not know how long.

India’s PSLV rocket places seven satellites into orbit

6:23 pm

India today (July 30th in India) successfully used its PSLV rocket to put seven satellites into orbit, launching from its coastal Satish Dhawan spaceport. This was the first time since India panicked over COVID and shut down in 2020 that the country has managed two launches within one month.

The leaders in the 2023 launch race:

51 SpaceX
30 China
9 Russia
6 Rocket Lab (with a launch planned for later tonight. Live stream here— Launch aborted at T-0)
6 India

American private enterprise still leads China in successful launches 58 to 30, and the entire world combined 58 to 50, with SpaceX by itself leading the entire world (excluding American companies) 51 to 50.

An apparent rocket section washes up on Australian coast

9:19 am

What appears to be a section of India’s PSLV rocket washed up on the western Australian coast yesterday, though at the moment the identity of the wreckage as not been confirmed.

Dr Alice Gorman, an expert in the field of space archaeology, said she believes the object is a fuel cylinder that came from the the third stage of India’s polar satellite launch vehicle rocket (PSLV), as many have suggested on social media.

The article includes a picture of that stage in orbit during a 2017 launch, and the similarity is obvious. If true, its specific launch at present remains unknown, though it appears it could have been floating in the ocean for years, a fact that is surprising in itself.

Voyager Space’s space station will use India’s manned capsule as ferry

10:11 am

Voyager Space, which is one of three consortiums building private space stations for NASA, has now signed a deal with India to begin work that would make possible using India’s Gaganyaan manned capsule as a ferry to Voyager’s Starlab space station.

Gaganyaan is presently under development. India hopes it will fly its first manned mission by 2025. Meanwhile, this international deal is not the first for Voyager. It has also signed launch contracts with India to use its two smaller rockets to launch payloads, as well as signed a development deal with Europe’s Airbus.

ISRO successfully test fires a throttleable version of an engine used in two of its rockets

10:03 am

ISRO on January 30, 2023 successfully completed a static fire test of a throttleable version of its Vikas rocket engine, used in the upper stage of both its PSLV and GSLV rockets as well as in the GSLV’S first stage, running the engine at 67 percent power for a time period of 43 seconds.

The ability to adjust the power level of the engine during launch will give ISRO the ability to attempt the recovery of the first stages, as well as expand the ability of these rockets to place more satellites per launch in different orbits.

India successfully places 1 satellite and 8 smallsats in orbit

11:43 pm

Using its PSLV rocket, India’s space agency ISRO successfully launched one ocean science satellite plus eight smallsats into orbit early on November 26, 2022.

This was India’s fourth successful orbital launch in 2022, tying it with Europe’s Arianespace. The leaders in the 2022 launch race however remain the same:

53 SpaceX
52 China
19 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 77 to 52 in the national rankings, but trails the rest of the world combined 81 to 77.

India’s PSLV rocket completes launch, putting nine satellites into orbit

9:08 am

India’s PSLV rocket successfully placed nine satellites into orbit today, completing that country’s second launch in 2022.

Since the Wuhan panic arrived in 2020, India’s space program has slowed to a crawl. Beforehand, it had been averaging six launches per year with the expectation that in 2020 it might double that number. Furthermore, the PSLV rocket had been a major player in the emerging smallsat market, routinely putting one to three dozen smallsats into orbit with each launch, with one launch in 2017 putting a record 104 smallsats into orbit.

Then the Wuhan panic arrived and everything stopped. Today’s PSLV launch was only its fifth launch since 2019. With almost all launches canceled, India’s smallsat business moved to SpaceX, Rocket Lab, and other rocket companies that did not panic and continued to launch.

Today’s launch however might signal a renewal. It was not managed by India’s old space agency, ISRO, but a new government agency called NewSpace India Limited (NSIL), which is supposedly focused on encouraging the growth of India’s commercial aerospace sector, independent of the government. Whether a government agency can accomplish such a task in India remains entirely unknown.

The leader board in the 2022 launch race remains the same:

27 SpaceX
21 China
8 Russia
4 Rocket Lab

American private enterprise still leads China 37 to 21 in the national rankings, and the entire world combined 37 to 34.

A ULA Atlas-5 launch later today could change these numbers.

ISRO hires company to build future PSLV rockets

9:13 am

Capitalism in space: For the first time, India’s space agency ISRO is about to hire a private company to build five PSLV rockets, rather than supervise the construction in-house.

Hindustan Aeronautics Limited (HAL) and L&T consortium has emerged as the lowest bidder to make 5 Polar Space Launch Vehicles (PSLVs) for ISRO. “The company is the lead partner with L&T sharing the work. Other vendors too will be involved with the consortium in the manufacturing of the launch vehicles (LVs). However, the contract is yet to be formalised/ awarded,” HAL said in a statement.

If all goes as planned, the first rockets will be delivered late in ’24.

This contract changes less than it seems, though it is a step in the right direction. ISRO has for years hired private subcontractors to build its rockets and components. What is different now is that it appears that HAL is now the lead contractor, not ISRO. HAL however does not appear to own the rockets it builds, and thus will not be able to build more to sell launches to others. Until this happens, India’s space industry will remain wholly government run.

OneWeb and Arianespace scramble to find a rocket to launch satellites

10:26 am

Capitalism in space: With the cancellation of the last six Soyuz-2 launches for OneWeb and Arianespace due to Russia’s invasion of the Ukraine, the two companies are struggling to find an alternative rocket to launch the remaining 216 satellites that would complete OneWeb’s satellite constellation.

OneWeb has already paid Arianespace for the launches, so the responsibility to get the satellites in orbit is at present Arianespace’s. The problem is that its flight manifest for both the Ariane-5 (being retired) and the new Ariane-6 rocket are presently full.

Going to another rocket provider is problematic, even if a deal could be negotiated. The flight manifest for ULA’s Atlas-5 and Vulcan rockets is also filled. Though SpaceX’s Falcon 9 could probably launch the satellites, that company’s Starlink satellite constellation is in direct competition with OneWeb, which makes it unlikely the two companies could make a deal.

There have been negotiations with India to use its rockets, but it is unclear at present whether this will work.

One other option is to buy a lot of launches from the smallsat rockets of Rocket Lab, Virgin Orbiter, and Astra. This will likely cost more because more launches will be required, and that would required a complex negotiation between all parties.

Wuhan panic continues to shut down India’s space agency

9:08 am

While most private companies and many nations, such as China and Russia, have been launching continuously since the advent of the coronavirus panic last year, India’s space agency ISRO continues to be shut down, completing few launches with a story today suggesting that the three remaining planned launches for 2021 will likely be delayed until next year.

There have only been two launches this year – the purely commercial PSLV C-51 launch in February carrying Brazil’s earth observation satellite Amazonia-1 and the GSLV-F10 mission in August carrying an Indian earth observation satellite EOS-03 that failed.

To be sure, the space agency has plans for three more missions before the end of the year, including the first development flight of the SSLV [Small Satellite Launch Vehicle]. The other two will use India’s workhorse PSLV to launch two earth observation satellites EOS-04 and EOS-06.

“The three planned missions appear unlikely this year,” a senior scientist at the agency said on condition of anonymity.

Worse, before the year began ISRO had reduced its targeted number of missions for ’21 from 16 to 5.

The article makes believe the epidemic has shut down other programs, such as Artemis, in the same way, but that is false. NASA’s Artemis program might have lost a few months in ’20 due to the agency’s panic over COVID, but since then it has been moving as fast as it can, considering the cumbersome nature of its engineering. Even Rocket Lab, which has been badly hampered by New Zealand draconian Wuhan rules, has managed to launch eleven times since January 2020, compared to the four launches attempted by India during that same time.

Whatever has caused the shut down at ISRO, it really hasn’t been the epidemic. Something about the agency’s management and its bureaucratic culture has prevented them from resuming flights. And as they remained stalled, the private commercial companies in the U.S. and China are grabbing their customers.

India & Russia successfully launch satellites

11:04 pm

Both India and Russia today successfully launched satellites into orbit.

For India it was their first launch in 2021. Their PSLV rocket put into orbit a Brazillian satellite for studying Earth resources. The launch also included 18 other cubesats.

Russia in turn used its Soyuz-2 rocket to launch a new generation weather satellite for studying that country’s remote Arctic regions.

SpaceX had also planned another Starlink launch but aborted the countdown with just over a minute to go. They plan to try again tomorrow.

The 2021 launch race:

5 SpaceX
4 China
3 Russia
1 Rocket Lab
1 Virgin Orbit
1 Northrop Grumman
1 India

The U.S. still leads China 8 to 4 in the national rankings.

India successfully completes second launch in 2020

8:42 am

Using its PSLV rocket India today successfully placed a communications satellite into orbit.

This was only the second launch by India in 2020. At the start of the year ISRO had predicted they would complete as many as twelve launches. Instead, their panic over COVID-19 shut them down.

The leader board for the 2020 launch race presently stands unchanged, though a SpaceX rocket is on the launchpad and might lift-off in the next 90 minutes. [UPDATE: SpaceX has stood down and will try again tomorrow.]

33 China
24 SpaceX
14 Russia
6 ULA
6 Rocket Lab

The U.S. still leads China 39 to 33 in the national rankings.

India successfully completes first launch in 2020

9:10 am

For the first time in 2020 India has launched a rocket, successfully placing ten satellites into orbit using its PSLV rocket.

The primary payload was an Indian Earth resource satellite dubbed EOS-1.

When the year started ISRO, India’s space agency, had predicted it would complete twelve launches in 2020, which would have been a record for their nation. Then the panic over COVID-19 set in, and they canceled everything for months on end. This long stand down will likely cause delays in all their long term programs including their effort to launch their own astronauts on their own rocket in their own capsule.

The leaders in the 2020 launch race remain the same:

28 China
19 SpaceX
12 Russia
4 ULA
4 Europe (Arianespace)
4 Rocket Lab

The U.S. remains ahead of China 30 to 28 in the national rankings..

Russia and India launch satellites

8:18 am

Two launches since yesterday. First, Russia used its Soyuz-2 rocket to place another GPS-type Glonass satellite into orbit. This was Russia’s 20th successful launch in 2019, the first time that country has hit that number since 2015.

Then India used its PSLV rocket to launch a military radar reconnaissance satellite.

The leaders in the 2019 launch race:

29 China
20 Russia
12 SpaceX
7 Europe (Arianespace)

India to use PSLV 4th stage for orbital research and docking tests

8:49 am

The new colonial movement: India’s space agency ISRO now plans to conduct research, including docking tests, using the 4th stage of its PSLV rocket following normal commercial operations.

The PS4 is the last stage of the Polar Satellite Launch Vehicle (PSLV) rocket, which until now used to go waste after putting the spacecraft into the desired orbit. ISRO, in the last two attempts tried to keep PS4 alive in space, and was successful. As the next step, it has now called for experiments from national and international institutions. The experiments will cover six areas, including space docking

“The PS4-Orbital Platform (PS4-OP) refers to a novel idea formulated by ISRO to use the spent PS4 stage (fourth stage of PSLV) to carry out in-orbit scientific experiments for an extended duration of one to six months. The advantage being the stage has standard interfaces & packages for power generation, telemetry, tele-command, stabilization, orbit keeping & orbit maneuvering,” Isro said on Saturday.

All of this is engineering research, finding ways to operate in space effectively. More important, they are doing what SpaceX does, letting their commercial operations pay for their research and development. Rather than fly separate missions to do these engineering experiments, they will let their commercial customers pay for it.

That India at this stage ties Russia says as much about India’s growing presence as a space power as it does about Russia’s fading presence.

In the national rankings, the U.S. still leads China 10 to 7.

India launches military satellite plus 28 smallsats

8:47 am

Capitalism in space: India today successfully used its PSLV rocket to launch one Indian military satellite plus 28 smallsats.

The rocket’s fourth stage demonstrated an additional capability.

Monday’s launch, the second of the year for India’s Polar Satellite Launch Vehicle (PSLV), was tasked with a series of maneuvers for the rocket’s upper stage to insert twenty-nine deployable payloads into their pre-planned orbits over the first two hours of its flight.

Following separation of the last payload, the upper stage will maneuver to a final orbit where it will operate as a research platform, hosting three attached payloads to demonstrate this capability for future missions. The launch also tests out a new configuration for the PSLV, a further intermediate between the lightest and heaviest versions of the rocket.

UPDATE: Yesterday China also launched a communications satellite designed to facilitate in-space communications, using its Long March 3B rocket.

The leaders in the 2019 launch race:

4 China
3 SpaceX
3 Europe (Arianespace)
2 Russia
2 India

The U.S. continues to lead China in the national rankings 6 to 4.

India’s PSLV rocket successfully launches military satellite

11:21 am

The new colonial movement: India today successfully launched a military reconnaissance satellite using a new configuration of its PSLV rocket.

The launch was broadcast live here and is still on-going as I write.

Thursday’s launch, the forty-sixth overall for the Polar Satellite Launch Vehicle (PSLV), marks the maiden flight of the rocket’s new PSLV-DL configuration. Filling a gap in payload capacity between two of the rocket’s existing configuration, the PSLV-DL will help reduce the cost of India’s access to space. Its first payload consists of a demonstration satellite built around the rocket’s upper stage, testing this concept for future applications, and a military spacecraft with an imaging payload.

During the speeches after the launch, the head of ISRO, K. Sivan, did several things of note. First, he introduced the launch’s mission director and explained that this was his last PSLV launch, as he is leaving the program to take over important aspects of their manned program, dubbed Gaganyaan. Then he let this man speak, giving him a big platform that suggests he is definitely a rising star in their program. Unfortunately, I was not able to catch his name. We shall see him again, however, for sure.

Sivan also noted that the deadline for that first manned mission is December 2021. He also outlined the next few missions, including Chandrayaan-2 to the Moon.

The 2019 launch standings:

2 China
1 SpaceX
1 Japan
1 ULA

The U.S. and China are tied 2-2 in the national rankings.

Successful launch tonight for India’s PSLV rocket

10:50 pm

The new colonial movement: India’s PSLV rocket successfully placed 31 satellites into orbit, including an Indian Landsat-type satellite plus 30 commercial smallsats.

This ties India with Japan at six launches for the year. With one more launch scheduled for this year, they should end up ahead of Japan.

The leaders in the 2018 launch race remain unchanged.

33 China
18 SpaceX
11 Russia
9 Europe (Arianespace)
8 ULA

At 95 total successful launches so far this year, 2018 now matches the total from 1993, the last time the global aerospace industry accomplished that many. That year, China and Japan had one launch each, Europe seven, with the rest by Russia and the U.S. Now the wealth is much more widely spread, and has a strong potential to grow significantly in the next few years.

India tests upgraded rocket engine

10:17 pm

The new colonial movement: India’s space agency ISRO has successfully tested an upgraded version of the Vikas rocket engine it uses in its PSLV and GSLV rockets.

The test was conducted on Sunday, and validated the performance adequacy of Vikas Engine to be used in the upcoming second developmental flight of GSLV Mk-III

Vikas Engine, a workhorse liquid rocket engine designed by the Indian Space Research Organsiation (ISRO), powers the second stage of Polar Satellite Launch Vehicle (PSLV) of India. It also powers the second stage and the fourth strap of Geosynchronous Launch Vehicle (GSLV) and the twin-engine core liquid stage (L110) of GSLV Mk-III.

Essentially India here is doing what SpaceX did with its Merlin engine. Rather than start over with a new engine, they are upgrading it, a process that is faster and less expensive. And as they do it, they remain operational and competitive in the launch market, with as many as five launches now scheduled before the end of 2018.

India’s PSLV successfully launches GPS satellite

11:53 pm

India’s PSLV rocket tonight successfully launched a replacement GPS satellite for its navigational system, replacing the satellite lost on a PSLV launch last year.

The leaders in the 2018 launch standings:

11 China
7 SpaceX
3 Japan
3 Russia
3 ULA
3 Europe
3 India

It surely is getting crowded near the bottom. It is also interesting that nations like India and Japan are still running neck and neck with Russia and Europe. Just last year their total launches didn’t match Europe’s, and was just a touch over half of Russia’s.

Update: News articles today say that, according to the head of ISRO, India is aiming for another 9 launches in 2018, for a total of 12, a new record for that country, while Russia’s space chief says they will complete 30 launches before the end of the year. I think India’s prediction is accurate, while Russia’s is hogwash.

India and ULA complete first launches in 2018

6:41 pm

The competition heats up: In what looks like the beginning of what might be the most active launch year in almost three decades, India and ULA today each successfully completed their first launches of 2018.

ULA’s Delta 4 rocket launched a U.S. reconnaissance satellite, while India’s PSLV rocket placed in orbit 31 satellites, 30 of which were smallsats. For India, this was their first launch since an August PSLV launch failed when the rocket fairing did not release.

Update: I just discovered that China launched its second rocket yesterday, placing it in a tie with U.S. for most launches and ahead of everyone else.

India aims to double launches in 2018

4:39 pm

The new colonial movement: The head of India’s space agency ISRO said in a newspaper interview today that the agency hopes to more than double the number of launches it completes in 2018, increasing the number to between 10 to 12 launches from the four successful launches in 2017.

“We are targeting 10 to 12 launches next year. The communication satellite GSAT-6A and Chandrayaan-2 mission will be launched by GSLV-Mk-II rockets. The second mission of GSLV-Mk-III rocket with a communication satellite and the launch of navigation satellite also will take place next year”, Kiran Kumar explained.

The much-awaited Chandrayaan-2 mission could be launched in the second quarter of 2018. “The moon lander is ready for the mission and undergoing tests. The flight hardware is getting assembled and going through tests. We are targeting the second quarter of the next year for the launch”, the top scientist said.

The two GSLV launches are critical, as this larger rocket is needed for India to really compete in the international market.

India’s next launch might slip to 2018

9:22 am

India’s next PSLV commercial launch might slip to 2018, despite months of effort to resume launches in 2017 following the August 31 PSLV launch failure when the rockets fairing did not release.

“We are working towards it. It will be in the end of December or first week of January. In that time frame,” ISRO Chairman A S Kiran Kumar said.

Kumar also said ISRO will try to launch on an average of once a month in 2018. The article also mentions the new and very oppressive Indian space law that has been proposed.

Asked whether the Space Activities Bill, 2017 would come up during the Budget session of Parliament, Kiran Kumar said “We have now put it in public comments. It would have to go through a set of discussions. The process has started.”

The draft of the proposed Bill to promote and regulate space activities of India, along with encouraging the participation of the private sector, has been uploaded on the ISRO website for comments from stakeholders and the public. [emphasis mine]

The highlighted text is typical of all news reports coming from India. The law does no such thing, and in fact will strongly discourage any work by the private sector. It appears that in India reporters either do not read the text of laws they are reporting on, or they really do not have freedom of the press there.
