India successfully launches its SSLV rocket on 2nd attempt

9:32 pm

On its second launch attempt tonight, India’s SSLV rocket (Small Satellite Launch Vehicle) successfully reached orbit and deployed all three of its smallsat payloads.

On the first launch attempt in August 2022, the engine on the fourth stage, used to put the satellites in their preferred orbits, shut down prematurely due to a failure of its guidance system. Today, all worked as planned.

The hope of India’s space agency ISRO is that this rocket can garner some of the growing smallsat business. That it is three years delayed because of ISRO’s panic over Wuhan makes fulfilling that hope more difficult, because so much of that business has now been grabbed by other companies.

The 2023 launch race:

9 SpaceX
5 China
2 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise still leads China 10 to 5 in the national rankings, and the entire world combined 10 to 9.

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.

The landing sites for two upcoming lunar landers

9:51 am

Map of Moon's south pole
Click for interactive map.

The approximate landing sites for two different lunar landers have now been revealed.

The map to the right, with the south pole indicated by the white cross, shows both, plus the planned landing site for Russia’s Luna-25 lander, presently targeting a summer ’23 launch. The green dot marks Luna-25’s landing site, inside Boguslawsky Crater.

The red dot marks the landing site in for India’s Chandrayaan-3 lunar lander/rover, now tentatively scheduled for launch by the end of ’23. This mission will put a small rover on the surface, and is essentially a redo of the failed Chandrayaan-2 mission from 2019.

The yellow dot in Malapert-A crater is now the likely landing site for Intuitive Machines Nova-C lander. This site is a change from the spacecraft’s original landing site in Oceanus Procellarum (where Astrobotic’s Peregrine lander is now going). In making this change, the launch of Nova-C also slipped to late June 2023, from the previously announced launch date of early 2023.

ISRO completes investigation into failure of its SSLV rocket on first launch

9:40 am

India’s space agency ISRO today released the results of its investigation into the launch failure of its SSLV rocket on its first flight in August 2022.

The investigation revealed that there was a vibration disturbance for a short duration on the Equipment Bay (EB) deck during the second stage separation. SSLV is a three-solid-stage launch vehicle unlike the PSLV, which is a four-stage rocket. The vibration affected the Inertial Navigation System (INS), resulting in declaring the sensors faulty by the logic in the Fault Detection & Isolation (FDI) software.

In plain English, it appears the vibration caused a failure in the inertial navigation system, thus resulting in the premature engine shutdown of the fourth stage.

According to the report, the problem has been fixed and the next SSLV launch is now tentatively scheduled for February 9, 2023.

ISRO about to test land a prototype of India’s own version of the X-37B

9:46 am

ISRO's own X-37B copy

According to S. Somanth, the head of India’s space agency ISRO, it will attempt the first flight on January 28, 2023 of a prototype reusable launch vehicle, similar to the Space Force’s X-37B.

According to ISRO’s website, Saturday’s landing demonstration will involve a “landing experiment (LEX)” in which the RLV will be carried using a helicopter to an altitude of 3-5 km and released at approximately 4-5 km from the runway with a horizontal velocity.

After the release, the RLV glides and navigates toward the runway, and carries out a conventional autonomous landing. This is planned in a defence airfield near Chitradurga in Karnataka.

The graphic to the right shows the flight profile of earlier tests that landed in the ocean. If this runway test is successful, it appears ISRO will next attempt an orbital flight and return.

Updates on India’s space effort

8:46 am

It appears that India’s effort in space is evolving rapidly, based on several news stories today.

First, the Indian space agency ISRO signed a deal with Microsoft, whereby the software giant will provide support to private Indian space start-ups.

As part of a memorandum of understanding that Microsoft has signed with the Indian Space Research Organization, the firm will also provide space tech startups with go-to-market support and help them become enterprise ready, it said.

Startups handpicked by ISRO will be onboarded to Microsoft for Startups Founders Hub platform, where they will receive free access to several tools and resources. These tools include help with building and scaling on Azure, as well as GitHub Enterprise, Visual Studio Enterprise, Microsoft 365 and Power BI and Dynamics 365. [emphasis mine]

The highlighted phrase indicates once again that there is an aggressive turf war going on in India about who will control the aerospace industry. Similar to the battles that occurred at NASA in the 00s and 10s, there are people within ISRO who do not wish to cede their power to an independent private industry, and are doing whatever they can to block the Modi government’s effort to create such an independent industry.

In the end, as long as Modi government stands firm, this effort will fail. Private companies will increasingly succeed, and that success will feed the transition from a government-run industry to an independent and competitive one.

The uncertainties surrounding India’s proposed first manned mission

10:00 am

Link here. The article does a nice job of outlining the program, dubbed Gaganyaan, as well as the many issues that has caused the first launch to be delayed more than three years.

The key quote however is this:

Despite the government claiming that there would be no delays due to Covid, the first uncrewed flight was rescheduled from 2020 to 2021 and then again to 2022. The dates were once again revised to late 2023 or early 2024, announced Union minister of state for science and technology Jitendra Singh in September this year. [emphasis mine]

The highlighted claim is quite amusing, considering how India’s government space agency ISRO shut down entirely because of the Wuhan panic for more than two years, and remains somewhat dormant even now. As a result of that panic, ISRO lost almost its entire commercial market to American companies.

Read the entire article. It summarizes the state of Gaganyaan in good detail, which also implies that a first launch in ’24 remains questionable.

Rocket startup Agnikul Cosmos opens first commercial launchpad in India

9:09 am

Capitalism in space: The Indian rocket startup Agnikul Cosmos has completed construction on the first privately owned launchpad in India, with the first suborbital launch planned before the end of this year.

Agnikul’s infrastructure comprises a launchpad and a Mission Control center 4 kilometres away, both within ISRO’s facilities on the island located off the coast of Chennai. The space pad was designed by Agnikul, constructed over two months, and is a part of the MoU signed between ISRO and Agnikul (among other space startups) under the new regulatory authority IN-SPACe’s first batch of support projects for private companies from ISRO.

Currently, it is capable of launching Agnikul’s rocket, the Agnibaan. [emphasis mine]

The first test launch is apparently not going to be orbital, but a technology test of the launch pad, its fueling facilities, and the 3D-printed engine Agnikul has built for Agnibaan.

The highlighted words once again note the effort by the Indian government to emulate the U.S. policy in the past decade to transition from a government-run space program to a privately-run competing and chaotic space industry. This MoU (memorandum of understanding) probably resembles the first space act agreements NASA issued to SpaceX and Orbital ATK. The agreements gave private companies aid and assistance, but the companies retained full ownership of what they build, and were left free to design things as they saw fit, not as the government dictated.

That two different Indian companies, Agnikul and Skyroot, are on the verge of their first orbital launches signals that this policy is succeeding. Agnikul has tested its engines and built its launchpad. Skyroot has completed its first suborbital launch.

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 about to do first drop test of its home-built version of an X-37B

10:31 am

India’s space agency ISRO is now preparing for the first drop test of its own home-built version of an X-37B mini-shuttle, designed to remain in orbit for a period of time, return to Earth on a runway, and then be reused.

According to ISRO officials, the RLV [Reusable Launch Vehicle] wing body will be carried using a helicopter to an altitude of three to five km and released at a distance of about four to five km ahead of the runway with a horizontal velocity. After the release, the RLV will glide, navigate towards the runway and land autonomously with a landing gear in the defence airfield near Chitradurga.

A prototype of the RLV was flown on a suborbital test flight in 2016, landing in the ocean. The pending test would be the first to attempt a runway landing, essential if the spacecraft is to safely return to Earth and then be reused.

OneWeb paid ISRO about $130 million for two GSLV launches

8:56 pm

It appears that OneWeb agreed to pay India’s space agency ISRO about $130 million for two GSLV launches, putting up 36 satellites on each launch.

When asked how much his business would spend to have 72 satellites launched, OneWeb Chairman Sunil Bharti Mittal told reporters in India that it would be more than Rs 1,000 crore.

Rs 1,000 crore translates to about $130 million, which means OneWeb paid about $65 million per launch, which is comparable to SpaceX’s standard Falcon 9 price, before discounts for using previously launched boosters.

It also appears that at present this deal is the only one between ISRO and OneWeb, and that the remaining 576 satellites that OneWeb needs to launch to complete its constellation are still open for others. At present, SpaceX and Relativity have contracts, though it is unclear how many each will launch. I suspect SpaceX will be the majority, since Relativity has not even completed its first test launch. It is also possible that ISRO will get more contracts based on its first launch success.

India’s GSLV-Mark3 rocket launches 36 OneWeb satellites

11:58 am

India’s GSLV-Mark3 rocket, its most powerful, has successfully placed 36 OneWeb satellites into orbit. As of this writing, the first 16 of the 36 satellites had successfully deployed.

This was the first international commercial launch for the GSLV rocket, previously used exclusively for Indian launches. It was also the first launch of OneWeb satellites since its deal with Russia was broken off due to the Ukraine war. Though the company had also quickly signed SpaceX to resume launches, I suspect that since half of OneWeb is owned by a major Indian investment company, India was given favored treatment in determining who would launch first.

This was the third successful launch in 2022 for India, the most since that country shut down in 2020 due to its panic over the Wuhan flu.

The leaders in the 2022 launch race remains unchanged:

48 SpaceX
45 China
16 Russia
8 Rocket Lab
7 ULA

American private enterprise still leads China 68 to 45, though it now trails the world combined 70 to 68.

Chandrayaan-3 now scheduled for summer 2023

10:01 am

India’s second attempt to put a rover on the surface of the Moon, Chandrayaan-3, has now been tentatively scheduled for launch in the summer of 2023.

The launch had originally been scheduled for launch in the fall of 2020, but was delayed when India shut down due to the Wuhan panic. Official at ISRO, India’s space agency, had hoped to launch by the summer of 2022, but that proved impossible. They have now delayed the mission a full year.

In fact, all earlier reports had indicated the rover was almost ready. This new delay of a full year suggests that some new issues might have been identified.

The news article at the link also notes that ISRO is now planning two unmanned orbital missions plus four launch abort tests before launching its first manned mission, dubbed Gaganyaan, not two abort tests as previously planned. They are still targeting ’24 for the manned mission.

India’s Mars orbiter mission ends after eight years

6:17 pm

After eight years in orbit around Mars, India’s Mars orbiter mission, Mangalyaan, has run out of fuel for controlling its orientation, ending its mission.

The Rs 450 crore Mars Orbiter Mission was launched onboard PSLV-C25 on November five, 2013, and the MOM spacecraft was successfully inserted into Martian orbit on September 24, 2014 in its first attempt. “Right now, there is no fuel left. The satellite battery has drained,” sources in the Indian Space Research Organisation (ISRO) told PTI. “The link has been lost”.

There was, however, no official word from the country’s national space agency, headquartered here.

During its mission it produced more than a thousand images, though the mission’s primary objective was technological, proving that India itself could design, build, launch, and manage a planetary mission to another world. For India, Mangalyaan was thus an unqualified success.

Indian smallsat rocket startup hopes to complete 1st launch this year

10:16 am

The new colonial movement: A new Indian private commercial rocket startup, Agnikul, now hopes to complete the first launch of its Agnibaan rocket before the end of 2022.

Whether or not this launch happens this year, the important thing is the existence of this private independent rocket company in India. Up until now, India’s government space bureaucracy in ISRO, and in its new commercial arm, NSIL, has controlled all of that country’s commercial market share. Like NASA before 2008, it has worked aggressively to keep independent players out.

Agnikul’s existence suggests the Modi government’s effort to emulate the U.S. and create an independent private space industry is beginning to bear fruit. If so, expect big things over the next decade from India in space.

India’s space agency successfully tests prototype for controlling descent of spent 1st stages

9:38 am

IAD by ISRO

India’s space agency ISRO on September 3, 2022 successfully used a suborbital sounding rocket to test a prototype of an inflatable airbag, which it dubs an Inflatable Aerodynamic Decelerator (IAD), that can inflate at the top of a 1st stage and slow and control its descent back to Earth after launch.

The graphic to the right was adapted from the mission brochure [pdf]. According to ISRO:

The IAD was initially folded and kept inside the payload bay of the rocket. At around 84 km altitude, the IAD was inflated and it descended through atmosphere with the payload part of sounding rocket. The pneumatic system for inflation was developed by LPSC. The IAD has systematically reduced the velocity of the payload through aerodynamic drag and followed the predicted trajectory. This is first time that an IAD is designed specifically for spent stage recovery. All the objectives of the mission were successfully demonstrated

ISRO claims this design can not only facilitate the reuse of first stages, it can also be used for science payloads to Mars and Venus.

I look at this and wonder, wouldn’t parachutes or parasails, already developed and used numerous times in similar applications, do the same job? In fact, Rocket Lab has already successfully used parachutes to control the re-entry of its Electron first stages. Meanwhile, SpaceX uses simple and lightweight grid fins to control the descent of its Falcon 9 first stages, and simply fires that stage’s engines twice to slow it down for landing.

While there may be engineer advantages to this airbag design, the whole thing smacks of many of NASA’S complex test programs that never made it past prototype tests. The ideas always looked good, but they never were practical or cost effective.

Indian rocket startup raises $51 million in private investment capital

9:08 am

Capitalism in space: The Indian rocket startup Skyroot has just raised $51 million in private investment capital for the development of its smallsat rocket, Vikram-1.

Operating as a private aerospace manufacturer and commercial launch service provider in the country, the Hyderabad-headquartered startup has been working on its flagship Vikram series of small-life launch vehicles. The first among them, the Vikram 1, is slated to take to the skies by the end of the year and launch small satellites to space.

The $51 million is the most any private aerospace commercial company from India has ever raised in a single funding round.

Though the Modi government has publicly encouraged the development of a private, independent, commercial aerospace industry, India’s bureaucracy has generally acted to block this effort. In 2019 it convinced the government to create New Space India Limited (NSIL), a wholly government-owned entity which is designed to retain as much control over commercial market share as possible. As recently as one month ago, the NSIL webpage described itself as aiming to “capture” that commercial market. That revealed its purpose too obviously, so the website was rewritten to now say its goal is to “spur” the Indian aerospace sector.

Because NSIL gets government money and has full control over all of India’s already developed government rockets and space facilities, it has an enormous advantage, which acts to discourage investment in new private companies such as Skyroot. This is a similar situation that existed in the U.S. for more than a half century following Apollo. NASA had the resources, controlled all launches, and thus made private investment for independent companies hard to obtain.

This only changed when NASA began awarding contracts to private companies in 2008, whereby the rockets and spacecraft produced were not owned or designed by NASA. And NASA was only forced to do so because Elon Musk happened to have enough of his own money to finance SpaceX himself.

When ISRO (India’s agency) or NSIL begin awarding contracts like this, then company’s like Skyroot will begin to blossom.

OneWeb lost $229 million when Russia canceled its launches and confiscated its satellites

9:49 am

On September 1, 2022, OneWeb revealed that Russia’s cancellation of the last six or so OneWeb launches as well as Russia’s confiscation of 36 satellites cost the company $229 million.

Russia’s actions were the response by then head of Roscosmos, Dmitry Rogozin, to sanctions imposed on Russia by the west because of its invasion of the Ukraine. Rogozin’s petty response ended up shooting his space agency in the foot, because it ended up losing billions of dollars in foreign launch business, business that is not likely to return for decades.

OneWeb has since signed contracts with SpaceX, ISRO (India’s space agency), and Relativity for future launches. None of these have been firmly scheduled, though the first by SpaceX is tentatively planned for sometime before the end of the year.

Indian company delivers Gaganyaan fairing and high altitude launch abort motor to ISRO

10:28 am

Capitalism in space: The Indian private company, Hindustan Aeronautics Limited, yesterday delivered to India’s space agency ISRO the fairing and high altitude launch abort motor that will be used in Gaganyaan, that nation’s first manned spaceflight.

Though the article at the link does not say so, the fairings and abort motor will likely be used in one of two unmanned launch abort test flights ISRO intends to do before the actual manned mission, now set for sometime in ’24.

Hindustan Aeronautics is also a space company in India that will require watching. It not only built these major components for Gaganyaan, it also has built major components for India’s PSLV and GSLV rockets. It would not surprise me if the company eventually decides to build its own rocket, assuming the India government loosens the stranglehold it presently has over space and lets private companies compete against its government space operations. It was a similar stranglehold by NASA from the 1970s to the 2000s that squelched competition and innovation from the American private aerospace industry. When that ended, the renaissance in commercial space finally could begin.

UPDATE: It appears I was in error assuming Hindustan Aeronauts was a private company, as it is owned by the Indian government. I have edited the post above to reflect this. It appears the stranglehold the government has over India’s aerospace industry is no closer to loosening.

India’s new SSLV rocket fails on first launch attempt

10:53 am

Delayed years because of India’s panic over the Wuhan flu, the first launch of that country’s new Small Satellite Launch Vehicle (SSLV) failed today when the rocket’s fourth stage apparently did not fire its engines properly.

The problem appeared to be the SSLV’s terminal stage, called the velocity trimming module (VTM). According to the launch profile, the VTM was supposed to have burnt for 20 seconds at 653 seconds after launch. However, it burnt for only 0.1 seconds, denying the rocket of the requisite altitude boost. Two satellites onboard the rocket – the primary EOS-2 Earth-observing satellite and the secondary AzaadiSAT student satellite – separated from the vehicle after the VTM burnt.

As a result, the two satellites were put in an orbit that was too low, which quickly decayed, destroying both.

Since this launch failed, I do not count it in the launch totals for 2022.

Considering that this was SSLV’s first launch, it was in that sense a test, and a failure therefore is not unexpected. India’s real problem is that the launch was delayed so long because of the Wuhan panic, thus allowing other competitors to catch up and pass India. While it is certain ISRO will try again, and eventually succeed, it will not get the market share it would have had, had it launched in 2020 as originally planned.

India inaugurates its own space debris tracking facility

9:21 am

ISRO, India’s government space agency, today inaugurated its own space debris tracking facility, designed to track space junk much as the Space Force does in the U.S.

A new facility dubbed the System for Safe & Sustainable Operation has been inaugurated in Bengaluru that will deal with emerging threats from space debris.

The new facility will help India achieve its Space Situational Awareness (SSA) goals by providing comprehensive and timely information about the space environment. The system will alert the agency about probabilities of in-orbit collisions, fragmentation, atmospheric re-entry risk, space-based strategic information, hazardous asteroids and space weather forecasts.

Though China might have its own comparable facility, I am unsure. Even if it does, the U.S. military has been for decades the only nation that does this tracking and then provides the data to the world, at no cost. That India is now developing its own capability signals that nation’s desire to chart its own path in space that does not depend on the resources of others.

This facility also signals the shift in ISRO’s job. Before, this government agency built and owned India’s rockets, flying commercial missions for profit. Now, the Modi government wants to transfer those tasks to India’s private sector, with ISRO merely acting as a customer if it needs such services. This change however will reduce ISRO’s influence, something that factions within India’s government are resisting. By giving ISRO the new task of tracking space debris, the Modi government gives ISRO new responsibilities to replace the ones it is losing. This will ease the turf war and speed the transition to a competing commercial industry.

ISRO chief: India’s manned mission will be delayed

9:22 am

The new colonial movement: The head of India’s space agency ISRO revealed during a press conference following yesterday’s PSLV launch that he is delaying by one or two years Gaganyaan manned mission.

Indian Space Research Organisation (Isro) Chairman S Somanath on Thursday said the launch of the ambitious Gaganyaan mission, the country’s first manned space flight, cannot happen this year or next year as the agency is keen to ensure that all safety systems are in place.

Somanth’s comments confirm an earlier report. It appears he wants the agency to do at least two unmanned tests of the spacecraft’s crew abort system. He also want further tests of the GSLV rocket that will launch the manned capsule.

Somanth also indicated that India’s next attempt to land a rover on the Moon, Chandrayaan-3, might also be delayed from the presently scheduled August ’22 target launch as they review the lander’s systems.

OneWeb to resume satellite launches this year, complete constellation by mid-2023

9:24 am

Capitalism in space: According to one OneWeb official at a conference yesterday, the company now expects to resume launching its satellites on SpaceX and Indian rockets by the fourth quarter of this year and will complete its constellation by the second quarter of next year.

Launches were suspended when Russia refused to do a launch — and confiscated the 36 satellites — after Europe imposed sanctions in response to the Russian invasion of the Ukraine.

Speaking at the Fourth Summit for Space Sustainability by the Secure World Foundation and the U.K. Space Agency, Maurizio Vanotti, vice president of space infrastructure development and partnerships at OneWeb, said new launch agreements with SpaceX and NewSpace India Ltd. (NSIL) would allow the company to launch the remaining satellites of its first-generation system by the second quarter of 2023.

“Our plan is to be back on the launch pad in quarter four, after the summer, and to complete deployment of the constellation by quarter two next year,” he said. It will take several months after that final launch for the satellites to move to their operational orbits, he added. “We’re going to be in service with global coverage, 24/7, by the end of next year,” he said.

At present OneWeb has not revealed the breakdown of launches from the two companies.

India’s first private satellite manufacturing facility opens

10:31 am

Capitalism in space: At a ceremony today that included officials from the government, the private commercial company ANANTH opened India’s first private satellite manufacturing facility.

Located at Karnataka Industrial Area Development Board Aerospace Park, Bengaluru, the new establishment is equipped with clean rooms for spacecraft sub-systems manufacturing and is large enough to cater to four spacecraft simultaneously.

This unveiling is part of India’s effort to transition from a government-built space effort to one run by the private sector. In the past all satellite construction in India was designed, managed, and owned by India’s space agency ISRO. This facility will now take over that function, and do so not only for ISRO but for any private company that wishes to have a satellite built.

India’s press: End the endless launch delays at ISRO

9:55 am

The new colonial movement: An op-ed yesterday in one of India’s major news outlets demanded that its space agency ISRO end the launch delays that have now gone for more than two years since the beginning of the Wuhan panic, and get a number of military satellites into orbit.

The details are not really that important. What this op-ed suggests is that India’s press, and possibly its public, is now beginning to lose patience with ISRO’S reluctance to resume launches. It also suggests their own fear of the Wuhan flu has subsided.

The bottom line is that India has lost a lot of business in the past two years by its refusal to launch, especially in the smallsat market, and the only chance it has to regain that business is to resume launches, with a vengence.

India delays launch of manned mission to do two abort tests first

9:37 am

The new colonial movement: India’s space agency ISRO has decided to delay the launch of its Gaganyaan manned orbital mission at least one more year (until ’24) in order to do two abort tests of the capsule.

“The first Test Vehicle for this purpose is ready and we will launch it in September this year. The human capsule will be sent up 15 kilometres, we will simulate an abort and then the capsule will be safely brought down by parachutes into the sea,’’ Somanath, who is also Secretary, Department of Space, said.

The second Test Vehicle will be launched in December this year, sent to a greater height and then brought back after a similar simulation is carried out.

The mission had originally been scheduled to launch in ’22, but was delayed significantly by India’s panic over Wuhan.

ISRO successfully tests human-rated solid rocket booster

8:52 am

India’s space agency ISRO announced on May 13, 2022 that it had successfully tested the man-rated version of the solid rocket strap-on booster used on its GSLV Mark 3 rocket that will launch its first manned mission into space.

The 20 m long and 3.2 m diameter booster is the world’s second-largest operational booster with solid propellant. During this test, about 700 parameters were monitored and the performance of all the systems was normal.

Launch of the Gaganyaan manned mission is now targeting ’23.

OneWeb signs deal to launch additional satellites using India’s GSLV rocket

9:32 am

Capitalism in space: OneWeb yesterday announced that it has signed a contract with New Space India, the commercial arm of India’s space agency, to launch additional satellites using that nation’s GSLV rocket.

From the company’s press release:

The first launch with New Space India is anticipated in 2022 from the Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. The launches will add to OneWeb’s total in-orbit constellation of 428 satellites, 66 per cent of the planned total fleet, to build a global network that will deliver high-speed, low-latency connectivity.

The company refused to release any additional details. The deal however clearly indicates two things. First, OneWeb wants an alternative to using SpaceX for launching the satellites that the Russians had been previously contracted to put in space. This gives it flexibility should one or another company have issues. For example, SpaceX simply might not have the immediate capacity to launch all these satellites as quickly as OneWeb wants. This second deal distributes that capacity across two launch vendors.

Second, it is likely in the long run that India is going to get a lot of business from OneWeb. This gain for India is Russia’s total loss. The deal will also help get India out of its extended panic over the Wuhan flu. Since the arrival of COVID India’s space industry has ground to a halt, completing few launches. The OneWeb deal might force it to come back to life.

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.
