On the PixxelSpace constellation

By: VM
22 August 2025 at 05:30

The announcement that a consortium led by PixxelSpace India will design, build, and operate a constellation of 12 earth-observation satellites marks a sharp shift in how India approaches large space projects. The Indian National Space Promotion and Authorisation Centre (IN-SPACe) awarded the project after a competitive process.

What made headlines was that the winning bid asked for no money from the government. Instead, the group — which includes Piersight Space, SatSure Analytics India, and Dhruva Space — has committed to invest more than Rs 1,200 crore of its own resources over the next four to five years. The constellation will carry a mix of advanced sensors, from multispectral and hyperspectral imagers to synthetic aperture radar, and it will be owned and operated entirely by the private side of the partnership.

PixxelSpace has said the zero-rupee bid is a conscious decision to support the vision of building an advanced earth-observation system for India and the world. The companies have also expressed belief they will recover their investment over time by selling high-value geospatial data and services in India and abroad. IN-SPACe’s chairman has called this a major endorsement of the future of India’s space economy.

Of course the benefits for India are clear. Once operational, the constellation should reduce the country’s reliance on foreign sources of satellite imagery. That will matter in areas like disaster management, agriculture planning, and national security, where delays or restrictions on outside data can have serious consequences. Having multiple companies in the consortium brings together strengths in hardware, analytics, and services, which could create a more complete space industry ecosystem. The phased rollout will also mean technology upgrades can be built in as the system grows, without heavy public spending.

Still, the arrangement raises difficult questions. In practice, this is less a public–private partnership than a joint venture. I assume the state will provide its seal of approval, policy support, and access to launch and ground facilities. If it does share policy support, it will have to explain why that’s vouchsafed for the collaboration isn’t of being expanded to the industry as a whole. I also heard IN-SPACe will ‘collate’ demand within the government for the constellation’s products and help meet them.

Without assuming a fiscal stake, however, the government is left with less leverage to set terms or enforce priorities, especially if the consortium’s commercial goals don’t always align with national needs. It’s worth asking why the government issued an official request-for-proposal if didn’t intend to assume a stake, and whether the Rs-350-crore soft loan IN-SPACe originally offered for the project will still be available, repurposed or quietly withdrawn.

I think the pitch will also test public oversight. IN-SPACe will need stronger technical capacity, legal authority, procedural clarity, and better public communication to monitor compliance without frustrating innovation. Regulations on remote sensing and data-sharing will probably have to be updated to cover a fully commercial system that sells services worldwide. Provisions that guarantee government priority access in emergencies and that protect sensitive imagery will have to be written clearly into law and contracts. Infrastructure access, from integration facilities to launch slots, must be managed transparently to avoid bottlenecks or perceived bias.

The government’s minimal financial involvement saves public money but it also reduces long-term control. If India repeats this model, it should put in place new laws and safeguards that define how sovereignty, security, and public interest are to be protected when critical space assets are run by private companies. Without such steps, the promise of cost-free expansion could instead lead to new dependencies that are even harder to manage in future.

The Zomato ad and India’s hustle since 1947

By: VM
16 August 2025 at 09:45

In contemporary India, corporate branding has often aligned itself with nationalist sentiment, adopting imagery such as the tricolour, Sanskrit slogans or references to ancient achievements to evoke cultural pride. Marketing narratives frequently frame consumption as a patriotic act, linking the choice of a product with the nation’s progress or “self-reliance”. This fusion of commercial messaging and nationalist symbolism serves both to capitalise on the prevailing political mood and to present companies as partners in the nationalist project. An advertisement in The Times of India on August 15, which describes the work of nation-building as a “hustle”, is a good example.

I remember in engineering college my class had a small-minded and vindictive professor in our second year of undergraduate studies. He repeatedly picked on one particular classmate to the extent that, as resentment between the two people escalated, the professor’s actions in one arguably innocuous matter resulted in the student being suspended for a semester. He eventually didn’t have the number of credits he needed to graduate and had to spend six more months redoing many of the same classes. Today, this student is a successful researcher in Europe, having gone on to acquire a graduate degree followed by a PhD from some of the best research institutes in the world.

When we were chatting a few years ago about our batch’s decadal reunion that was coming up, we thought it would be a good idea to attend and, there, rub my friend’s success in this professor’s face. We really wanted to do it because we wanted him to know how petty he had been. But as we discussed how we’d orchestrate this moment, it dawned on us that we’d also be signalling that our achievements don’t amount to more than those necessary to snub him, as if to say they have no greater meaning or purpose. We eventually dropped the idea. At the reunion itself, my friend simply ignored the professor.

India may appear today to have progressed well past Winston Churchill’s belief, expressed in the early 1930s, but to advertise as Zomato has is to imply that it remains on our minds and animates the purpose of what we’re trying to do. It is a juvenile and frankly resentful attitude that also hints at a more deep-seated lack of contentment. The advertisement’s achievement of choice is the Chandrayaan 3 mission, its Vikram lander lit dramatically by sunlight and earthlight and photographed by the Pragyan rover. The landing was a significant achievement, but to claim that that above all else describes contemporary India is also to dismiss the evident truth that a functional space organisation and a democracy in distress can coexist within the same borders. One neither carries nor excuses the other.

In fact, it’s possible to argue that ISRO’s success is at least partly a product of the unusual circumstances of its creation and its privileged place in the administrative structure. Founded by a scientist who worked directly with Jawaharlal Nehru — bypassing the bureaucratic hurdles faced by most others — ISRO was placed under the purview of the prime minister, ensuring it received the political attention, resources, and exemptions that are not typically available to other ministries or public enterprises. In this view, ISRO’s achievements are insulated from the broader fortunes of the country and can’t be taken as a reliable proxy for India’s overall ‘success’.

The question here is: to whose words do we pay attention? Obviously not those of Churchill: his prediction is nearly a century old. In fact, as Ramachandra Guha sets out in the prologue of India After Gandhi (which I’m currently rereading), they seem in their particular context to be untempered and provocative.

In the 1940s, with Indian independence manifestly round the corner, Churchill grumbled that he had not becoming the King’s first minister in order to preside over the liquidation of the British Empire. A decade previously he had tried to rebuild a fading political career on the plank of opposing self-government for Indians. After Gandhi’s ‘salt satyagraha’ of 1930 in protest against taxes on salt, the British government began speaking with Indian nationalists about the possibility of granting the colony dominion status. This was vaguely defined, with no timetable set for its realization. Even so, Churchill called the idea ‘not only fantastic in itself but criminally mischievous in its effects’. Since Indians were not fit for self-government, it was necessary to marshal ‘the sober and resolute forces of the British Empire’ to stall any such possibility.

In 1930 and 1931 Churchill delivered numerous speeches designed to work up, in most unsober form, the constituency opposed to independence for India. Speaking to an audience at the City of London in December 1930, he claimed that if the British left the subcontinent, then an ‘army of white janissaries, officered if necessary from Germany, will be hired to secure the armed ascendancy of the Hindu’.

This said, Guha continues later in the prologue:

The forces that divide India are many. … But there are also forces that have kept India together, that have helped transcend or contain the cleavages of class and culture, that — so far, at least — have nullified those many predictions that India would not stay united and not stay democratic. These moderating influences are far less visible. … they have included individuals as well as institutions.

Indeed, reading through the history of independent India, through the 1940s and ’50s filled with hope and ambition, the turmoil of the ’60s and the ’70s, the Emergency, followed by economic downturn, liberalisation, finally to the rise of Hindu nationalism, it has been clear that the work of the “forces that have kept India together” is unceasing. Earlier, the Constitution’s framework, with its guarantees of rights and democratic representation, provided a common political anchor. Regular elections, a free press, and an independent judiciary reinforced faith in the system even as the linguistic reorganisation of states reduced separatist tensions. National institutions such as the armed forces, civil services, and railways fostered a sense of shared identity across disparate regions.

Equally, integrative political movements and leaders — including the All India Kisan Sabha, trade union federations like INTUC and AITUC, the Janata Party coalition of 1977, Akali leaders in Punjab in the post-1984 period, the Mazdoor Kisan Shakti Sangathan, and so on, as well as Lal Bahadur Shastri, Govind Ballabh Pant, C. Rajagopalachari, Vinoba Bhave, Jayaprakash Narayan, C.N. Annadurai, Atal Bihari Vajpayee, and so on — operated despite sharp disagreements largely within constitutional boundaries, sustaining the legitimacy of the Union. Today, however, most of these “forces” are directed at a more cynical cause of disunity: a nationalist ideology that has repeatedly defended itself with deceit, evasion, obfuscation, opportunism, pietism, pretence, subterfuge, vindictiveness, and violence.

In this light, to claim we have “just put in the work, year after year”, as if to suggest India has only been growing from strength to strength, rather than lurching from one crisis to the next and of late becoming a little more balkanised as a result, is plainly disingenuous — and yet entirely in keeping with the alignment of corporate branding with nationalist sentiment, which is designed to create a climate in which criticism of corporate conduct is framed as unpatriotic. When companies wrap themselves in the symbols of the nation and position their products or services as contributions to India’s progress, questioning their practices risks being cast as undermining that progress. This can blunt scrutiny of resource over-extraction, environmental degradation, and exploitative labour practices by accusing dissenters of obstructing development.

Aggressively promoting consumption and consumerism (“fuel your hustle”), which drives profits but also deepens social inequalities in the process, is recast as participating in the patriotic project of economic growth. When corporate campaigns subtly or explicitly endorse certain political agendas, their association with national pride can normalise those positions and marginalise alternative views. In this way, the fusion of commerce and nationalism builds market share while fostering a superficial sense of national harmony, even as it sidelines debates on inequality, exclusion, and the varied experiences of different communities within the nation.

Watch the celebrations, on mute

Right now, Shubhanshu Shukla is on his way back to Earth from the International Space Station. Am I proud he’s been the first Indian up there? I don’t know. It’s not clear.

The whole thing seemed to be stage-managed. Shukla didn’t say anything surprising, nothing that popped. In fact he said exactly what we expected him to say. Nothing more, nothing less.

Fuck controversy. It’s possible to be interesting in new ways all the time without edging into the objectionable. It’s not hard to beat predictability — but there it was for two weeks straight. I wonder if Shukla was fed all his lines. It could’ve been a monumental thing but it feels… droll.

“India’s short on cash.” “India’s short on skills.” “India’s short on liberties.” We’ve heard these refrains as we’ve covered science and space journalism. But it’s been clear for some time now that “India’s short on cash” is a myth.

We’ve written and spoken over and over that Gaganyaan needs better accountability and more proactive communication from ISRO’s Human Space Flight Centre. But it’s also true that it needs even more money than the Rs 20,000 crore it’s already been allocated.

One thing I’ve learnt about the Narendra Modi government is that if it puts its mind to it, if it believes it can extract political mileage from a particular commitment, it will find a way to go all in. So when it doesn’t, the fact that it doesn’t sticks out. It’s a signal that The Thing isn’t a priority.

Looking at the Indian space programme through the same lens can be revealing. Shukla’s whole trip and back was carefully choreographed. There’s been no sense of adventure. Grit is nowhere to be seen.

But between Prime Minister Modi announcing his name in the list of four astronaut-candidates for Gaganyaan’s first crewed flight (currently set for 2027) and today, I know marginally more about Shukla, much less about the other three, and nothing really personal to boot. Just banal stuff.

This isn’t some military campaign we’re talking about, is it? Just checking.

Chethan Kumar at ToI and Jatan Mehta have done everyone a favour: one by reporting extensively on Shukla’s and ISRO’s activities and the other by collecting even the most deeply buried scraps of information from across the internet in one place. The point, however, is that it shouldn’t have come to this. Their work is laborious, made possible by the fact that it’s by far their primary responsibility.

It needed to be much easier than this to find out more about India’s first homegrown astronauts. ISRO itself has been mum, so much so that every new ISRO story is turning out to be an investigative story. The details of Shukla’s exploits needed to be interesting, too. The haven’t been.

So now, Shukla’s returning from the International Space Station. It’s really not clear what one’s expected to be excited about…

Enfeebling the Indian space programme

By: VM
3 July 2025 at 13:15

There’s no denying that there currently prevails a public culture in India that equates criticism, even well-reasoned, with pooh-poohing. It’s especially pronounced in certain geographies where the Bharatiya Janata Party (BJP) enjoys majority support as well as vis-à-vis institutions that the subscribers of Hindu politics consider to be ripe for international renown, especially in the eyes of the country’s former colonial masters. The other side of the same cultural coin is the passive encouragement it offers to those who’d play up the feats of Indian enterprises even if they lack substantive evidence to back their claims up. While these tendencies are pronounced in many enterprises, I have encountered them most often in the spaceflight domain.

Through its feats of engineering and administration over the years, the Indian Space Research Organisation (ISRO) has cultivated a deserved reputation of setting a high bar for itself and meeting them. Its achievements are the reason why India is one of a few countries today with a functionally complete space programme. It operates launch vehicles, conducts spaceflight-related R&D, has facilities to develop as well as track satellites, and maintains data-processing pipeliness to turn the data it collects from space into products usable for industry and academia. It is now embarking on a human spaceflight programme as well. ISRO has also launched interplanetary missions to the moon and Mars, with one destined for Venus in the works. In and of itself the organisation has an enviable legacy. Thus, unsurprisingly, many sections of the Hindutva brigade have latched onto ISRO’s achievements to animate their own propaganda of India’s greatness, both real and imagined.

The surest signs of this adoption are most visible when ISRO missions fail or succeed in unclear ways. The Chandrayaan 2 mission and the Axiom-4 mission respectively are illustrative examples. As if to forestall any allegations that the Chandrayaan 2 mission failed, then ISRO chairman K. Sivam said right after its Vikram lander crashed on the moon that it had been a “98% success”. Chandrayaan 2 was a technology demonstrator and it did successfully demonstrate most of those onboard very well. The “98%” figure, however, was so disproportionate as to suggest Sivan was defending the mission less on its merits than on its ability to fit into reductive narratives of how good ISRO was. (Recall, similarly, when former DCGI V.G. Somani claimed the homegrown Covaxin vaccine was “110% safe” when safety data from its phase III clinical trials weren’t even available.)

On the other hand, even as the Axiom-4 mission was about to kick off, neither ISRO nor the Department of Space (DoS) had articulated what Indian astronaut Shubhanshu Shukla’s presence onboard the mission was expected to achieve. If these details didn’t actually exist before the mission, to participate in which ISRO had paid Axiom Space more than Rs 500 crore, both ISRO and the DoS were effectively keeping the door open to picking a goalpost of their choosing to kick the ball through as the mission progressed. If they did have these details but had elected to not share them, their (in)actions raised — or ought to have — difficult questions about the terms on which these organisations believed they were accountable in a democratic country. Either way, the success of the Axiom-4 mission vis-à-vis Shukla’s participation was something of an empty vessel: a ready receptacle for any narrative that could be placed inside ex post facto.

At the same time, raising this question has often been construed in the public domain, but especially on social media platforms, in response to arguments presented in the news, and in conversations among people interested in Indian spaceflight, as naysaying Shukla’s activities altogether. By all means let’s celebrate Shukla’s and by extension India’s ‘citius, altius, fortius’ moment in human spaceflight; the question is: what didn’t ISRO/DoS share before Axiom-4 lifted off and why? (Note that what journalists have been reporting since liftoff, while valuable, isn’t the answer to the question posed here.) While it’s tempting to think this pinched communication is a strategy developed by the powers that be to cope with insensitive reporting in the press, doing so would also ignore the political capture institutions like ISRO have already suffered and which ISRO arguably has as well, during and after Sivan’s term as chairman.

For just two examples of institutions that have historically enjoyed a popularity comparable in both scope and flavour to that of ISRO, consider India’s cricket administration and the Election Commission. During the 2024 men’s T20 World Cup that India eventually won, the Indian team had the least amount of travel and the most foreknowledge on the ground it was to play its semifinal game on. At the 2023 men’s ODI World Cup, too, India played all its matches on Sundays, ensuring the highest attendance for its own contests rather than be able to share that opportunity with all teams. The tournament is intended to be a celebration of the sport after all. For added measure, police personnel were also deployed at various stadia to take away spectators’ placards and flags in support of Pakistan in matches featuring the Pakistani team. The stage management of both World Cups only lessened, rather than heightened, the Indian team’s victories.

It’s been a similar story with the Election Commission of India, which has of late come under repeated attack from the Indian National Congress party and some of its allies for allegedly rigging their electronic voting machines and subsequently entire elections in favour of the BJP. While the Congress has failed to submit the extraordinary evidence required to support these extraordinary claims, doubts about the ECI’s integrity have spread anyway because there are other, more overt ways in which the once-independent institution of Indian democracy favours the BJP — including scheduling elections according to the availability of party supremo Narendra Modi to speak at rallies.

Recently, a more obscure but nonetheless pertinent controversy erupted in some circles when in an NDTV report incumbent ISRO chairman V. Narayanan seemed to suggest that SpaceX called one of the attempts to launch Axiom-4 off because his team at ISRO had insisted that the company thoroughly check its rocket for bugs. The incident followed SpaceX engineers spotting a leak on the rocket. The point of egregiousness here is that while SpaceX had built and flown that very type of rocket hundreds of times, Narayanan and ambiguous wording in the NDTV report made it out to be that SpaceX would have flown the rocket if not for ISRO’s insistence. What’s more likely to have happened is NASA and SpaceX engineers would have consulted ISRO as they would have consulted the other agencies involved in the flight — ESA, HUNOR, and Axiom Space — about their stand, and the ISRO team on its turn would have clarified its position: that SpaceX recheck the rocket before the next launch attempt. However, the narrative “if not for ISRO, SpaceX would’ve flown a bad rocket” took flight anyway.

Evidently these are not isolated incidents. The last three ISRO chairmen — Sivan, Somanath, and now Narayanan — have progressively curtailed the flow of information from the organisation to the press even as they have maintained a steady pro-Hindutva, pro-establishment rhetoric. All three leaders have also only served at ISRO’s helm when the BJP was in power at the Centre, wielding its tendency to centralise power by, among others, centralising the permissions to speak freely. Some enterprising journalists like Chethan Kumar and T.S. Subramanian and activists like r/Ohsin and X.com/@SolidBoosters have thus far kept the space establishment from resembling a black hole. But the overarching strategy is as simple as it is devious: while critical arguments become preoccupied by whataboutery and fending off misguided accusations of neocolonialist thinking (“why should we measure an ISRO mission’s success the way NASA measures its missions’ successes?”), unconditional expressions of support and adulation spread freely through our shared communication networks. This can only keep up a false veil of greatness that crumbles the moment it brooks legitimate criticism, becoming desperate for yet another veil to replace itself.

But even that is beside the point: to echo the philosopher Bruno Latour, when criticism is blocked from attending to something we have all laboured to build, that something is deprived of the “care and caution” it needs to grow, to no longer be fragile. Yet that’s exactly what the Indian space programme risks becoming today. Here’s a brand new case in point, from the tweets that prompted this post: according to an RTI query filed by @SolidBoosters, India’s homegrown NavIC satellite navigation constellation is just one clock failure away from “complete operational collapse”. The issue appears to be ISRO’s subpar launch cadence and the consequently sluggish replacement of clocks that have already failed.

6/6 Root Cause Analysis for atomic clock failures has been completed but classified under RTI Act Section 8 as vital technical information. Meanwhile public transparency is limited while the constellation continues degrading. #NavIC #ISRO #RTI

— SolidBoosters (@SolidBoosters) July 2, 2025

Granted, rushed critiques and critiques designed to sting more than guide can only be expected to elicit defensive posturing. But to minimise one’s exposure to all criticism altogether, especially those from learned quarters and conveyed in respectful language, is to deprive oneself of the pressure and the drive to solve the right problems in the right ways, both drawing from and adding to India’s democratic fabric. The end results are public speeches and commentary that are increasingly removed from reality as well as, more importantly, thicker walls between criticism and The Thing it strives to nurture.

Empathy for Donald Pettit

Empathy for Donald Pettit

There was an intriguing outpouring of concern worldwide when Sunita Williams and Barry Wilmore returned to Earth after 280-something days in space. People were particularly concerned about Williams’s health and how she was doing, as if Wilmore hadn’t been there with her living through the same mission.

Researchers are still studying the effects of prolonged spaceflight on human bodies and don’t yet have enough data to say with confidence that some effects are more pronounced in women’s bodies. More than a few astronauts have also flown longer missions. NASA also has exercise and medical check-up regimens in place for astronauts to follow during long-duration missions as well as once they return to the ground. Taken together, while the mission profile was unusual, the duo didn’t present NASA with challenges it didn’t already know how to address.

Williams likely received the attention she did because she is more popular and, in some parts of the world, for her Indian ancestry. Other than her being a veteran astronaut, a NASA scientist, and a good ambassador for human spaceflight, I don’t think she’s special in a way that could justify the world’s, including India’s, tunnel vision.

In fact, while there was considerable interest in the astronauts’ well-being onboard the International Space Station (ISS) after their original mission profile had been stretched from eight days to nine months, the world has a much better case study to focus on now — yet few seem bothered.

On April 20 (IST), Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner and NASA astronaut Donald “Don” Pettit returned from the ISS onboard a Soyuz capsule on its MS-26 mission. Of them, Pettit turned 70 years old on April 20. He is NASA’s oldest active astronaut. His most recent ISS expedition lasted 220 days and so far he has accumulated 590 days in space.

When the Soyuz MS-26 capsule touched down in Kazakhstan, NASA tweeted:

According to NASA officials at the landing site, @Astro_Pettit is doing well and in the range of what is expected for him following return to Earth.

What's expected for him? In his own words during an April 16 pre-departure interview, "This is a physiological thing. It affects…

— NASA (@NASA) April 20, 2025

Here’s the April 16 interview, where you can also listen to him talking about what the first thing he’s likely to do once he lands: poop. “It affects different people different ways,” he goes on to say about long space stays. “Some people can land and go out, eat pizza, and dance. When I land, it takes me about 24 hours to feel like I’m a human being again.”

According to Russian journalist (and a good source of spaceflight details coming out of that country) Anatoly Zak, Pettit didn’t look good coming out of the Soyuz capsule.

...The commentary indicates that Pettit was in a bad shape after extraction from the capsule...

— Anatoly Zak (@RussianSpaceWeb) April 20, 2025

That cameras at the landing were asked to point away from Pettit because he was in “bad shape” is so wholesome. Jonathan McDowell put it in terms we’d understand:

... thank goodness no one is around to video me on global TV as I collapse on the couch, close my eyes and groan feebly for about ten minutes...

— Jonathan McDowell (@planet4589) April 20, 2025

Right now, Williams, Wilmore, and Pettit will be going through NASA’s physical and mental rehabilitation programme for astronauts wrapping up long-term missions (as defined by NASA’s Office of the Chief Health and Medical Officer). It will last for at least 45 days and will be extended if an astronaut needs more help.

Once the rehabilitation is done, it will be good to hear from Williams, Wilmore, and Pettit about their missions. I do hope they will speak up and NASA will allow them to be candid.

A few weeks ago, Ars Technica published an article based on an intimate interview with Barry Wilmore. Both the fact of the article being published and the details that populated it were evidence of good journalism. But I’d rather astronauts who have been on such high-profile missions share all the details they’re allowed to with everyone in a public forum and that their government employers facilitate such interactions. This way what the people find out about doesn’t depend on which questions they already know to ask.

Of course, health possesses a tricky identity in this information landscape. I’m reminded of an article journalist Anoo Bhuyan wrote in 2018, after Bollywood actor Irrfan Khan revealed he had been diagnosed with a neuroendocrine tumour. In one evocative passage, Bhuyan laid out the starkly different ways in which Bollywood stars and Indian political leaders addressed public concerns about their medical state.

Bollywood celebrities have no responsibility to be accountable to the public about their health. Yet, they have often been transparent. However, same cannot be said about Indian politicians across parties and across the country. Sonia Gandhi, J. Jayalalithaa, Manohar Parrikar, Sushma Swaraj, Amar Singh and a number of other prominent figures have all been and continue to be tight-lipped about their health. More importantly, they are unaccountable about their inability to perform the jobs for which they were elected.

The empathetic coverage of Pettit as he exited the Soyuz capsule struck an edifying contrast with a lot of media coverage of Sunita Williams that sought details about her health that, should anyone have acquired them, would have constituted a violation of her privacy.

At the same time, human spaceflight is becoming an increasingly prominent preoccupation of many countries. It is both very expensive and, the way it is organised in India (guided as much by political ambitions as by scientific ones and with rarely proactive outreach), is hard to hold accountable.

What astronauts as prominent as Williams, Wilmore, and Pettit say — who are also experienced in ways that few others are — will go a long way towards allowing anyone with an internet connection to participate, learn, and keep up rather than become disengaged and left behind.

Yet the simple fact of an astronaut being a public figure doesn’t mean all their personal details should be availed for public consumption.

Shatrugan Sinha’s advice, as he provided it in Bhuyan’s article, is fitting here: that anyone should be able to share information about their ailments without fear of being removed from their current posts and of being discriminated against for it. The former is currently easier because it is techne — determined by the technical prowess of the times to cure a disease or ‘remove’ a condition’ — while the latter is harder for being episteme, a way of thinking and thus more firmly enmeshed In the mores of the time. Perhaps political leaders are tight-lipped because they know this better than anyone. It is nonetheless unfortunate.

Astronauts are more like film stars here: they owe us no accountability about how they are faring, but if they do elect to share, it can go a long away towards destigmatising the public perception of their work as well as understand what astronauts everywhere, including budding ones at home, are expected to go through.

Let’s allow space missions to be wonderful

Let’s allow space missions to be wonderful

Finally some external validation. After months of insisting Sunita Williams and Barry Wilmore aren’t “stuck” or “stranded” in the International Space Station, after Boeing Starliner’s first crewed flight test went awry, the two astronauts have themselves repudiated the use of such words to describe their mission profile so far. On February 18, Moneycontrol quoted a CNN report to say:

In an interview with CNN, Wilmore said they are neither abandoned nor stuck. “We come prepared and committed,” he stated, adding that all ISS astronauts have emergency return options. Williams also reflected on their space experience, saying, “Floating in space never gets old.”

Williams’s statement isn’t bravado just much as the use of “stranded” isn’t a matter of describing what’s right in front of us. Crewed missions to space are always more complicated than that. That’s why Boeing picked Williams and Wilmore in the first place: they’re veteran astronauts who know when not to panic. To quote from a previous post:

The history of spaceflight — human or robotic — is the history of people trying to expect the unexpected and to survive the unexpectable. That’s why we have test flights and then we have redundancies. For example, after the Columbia disaster in 2003, part of NASA’s response was a new protocol: that astronauts flying in faulty space capsules could dock at the ISS until the capsule was repaired or a space agency could launch a new capsule to bring them back. So Williams and Wilmore aren’t “stuck” there: they’re practically following protocol.

For its upcoming Gaganyaan mission, ISRO has planned multiple test flights leading up the human version. It’s possible this flight or subsequent ones could throw up a problem, causing the astronauts within to take shelter at the ISS. Would we accuse ISRO of keeping them “stuck” there or would we laud the astronauts’ commitment to the mission and support ISRO’s efforts to retrieve them safely?

… “stuck” or “stranded” implies a crisis, an outcome that no party involved in the mission planned for. It creates the impression human spaceflight (in this particular mission) is riskier than it is actually and produces false signals about the competencies of the people who planned the mission. It also erects unreasonable expectations about the sort of outcomes test flights can and can’t have.

Narratives matter. Words don’t always describe only what the senses can perceive. Certain words, including “stuck” and “stranded”, also impute intentions, motive, and agency — which are things we can’t piece together without involving the people to whom we are attributing these things (while ensuring they have the ability and opportunity to speak up). Wilmore says he’s “committed”, not “stuck”. When Williams says “floating in space never gets old”, it means among other things that she’s allowed to define her journey in that way without only navigating narratives in which she’s “stranded”.

In fact, as we make more forays into space — whether specific tasks like taking a brand new crew capsule for its first spin, guiding robots into previously uncharted areas of space or ourselves going where only robots have been before — we need to stay open to the unexpected and we need to keep ready a language that doesn’t belittle or diminish the human experience of it, which by all means can be completely wonderful.

Finally, I support restricting our language to what’s right in front of us in the event that we don’t know, which would be to simply say they’re in space.

Subtracting from science funding

NavIC’s hurdles project govt’s reluctance to fund innovation’, Hindustan Times, February 7, 2025:

India … chose a more cautious path. For decades, we’ve been telling ourselves that we’ll invest in science “when we’re economically better off.” It’s both prudent and a paradox. How do you become economically better off without investing in the very thing that drives development in the first place? It’s like waiting to plant a tree until you’re sure it will bear fruit tomorrow. That hesitation shows in the numbers: India spends just 0.6% of its GDP on scientific research. For comparison, China spends over 2.5%, and the United States spends 3%.

Charles Assisi has an interesting analysis of the partial failure of the NVS-02 mission. (‘Partial’ because ISRO is currently looking to repurpose the satellite. The terms of this exercise aren’t yet clear.) “When you’re constantly short of funds, every setback feels heavier” — spot on. In fact, my cynical self inclined is inclined ask him if he really believes the present government is interested in stoking development when it has been making the right noises, but only noises, about increasing the private sector’s contribution to R&D expenses while allowing the growth of the public sector’s contribution to grow more slowly than the GDP.

This said, I’m more curious about the final sentence of the same paragraph:

Worse still, when you dig into the details, much of India’s scientific budget is buried within defense spending, which means it doesn’t always trickle down to civilian applications or long-term innovation.

Unless growth in defence spending has somehow exactly matched decline in spending on R&D, I’m curious how defence alone can be said to have subtracted from science. Perhaps it did, perhaps it didn’t, but I wouldn’t have used the argument because it presumes whatever that money was spent on didn’t have civilian interests at heart. It’s a strawman. It isn’t a crime without a victim either because of the notion that the scientific enterprise is incapable of delivering anything less than “civilian applications or long-term innovation”, even with sufficient funding. The arc of the scientific enterprise doesn’t bend towards the public interest by itself.

It’s also possible that what the R&D budget lost, the nuclear establishment gained — and I could get behind that. But beyond the subtraction itself, the question of which ministry or sector benefited is meaningless. The finance ministry makes its allocations from a large pool, and it only makes sense to talk about what science lost in terms of what science lost, rather than because X gained rather than Y.

The pitfalls of Somanath calling Aditya L1 a “protector”

In a WhatsApp group of which I’m a part, there’s a heated discussion going on around an article published by NDTV on June 10, entitled ‘Sun’s Fury May Fry Satellites, But India Has A Watchful Space Protector’. The article was published after the Indian Space Research Organisation (ISRO) published images of the Sun the Aditya L1 spacecraft (including its coronagraph) captured during the May solar storm. The article also features quotes by ISRO chairman S. Somanath — and some of them in particular prompted the discussion. For example, he says:

“Aditya L1 captured when the Sun got angry this May. If it gets furious in the near future, as scientists suggest, India’s 24x7X365 days’ eye on the Sun is going to provide a forewarning. After all, we have to protect the 50-plus Indian satellites in space that have cost the country an estimated more than ₹ 50,000 crore. Aditya L1 is a celestial protector for our space assets.”

A space scientist on the group pointed out that any solar event that could fry satellites in Earth orbit would also fry Aditya L1, which is stationed at the first Earth-Sun Lagrange point (1.5 million km from Earth in the direction of the Sun), so it doesn’t make sense to describe this spacecraft as a “protector” of India’s “space assets”. Instead, the scientist said, we’re better off describing Aditya L1 as a science mission, which is what it’d been billed as.

Another space scientist in the same group contended that the coronagraph onboard Aditya L1, plus its other instruments, still give the spacecraft a not insignificant early-warning ability, using which ISRO could consider protective measures. He also said not all solar storms are likely to fry all satellites around Earth, only the very powerful ones; likewise, not all satellites around Earth are equally engineered to withstand solar radiation that is more intense than usual, to varying extents. With these variables in mind, he added, Aditya L1 — which is protected to a greater degree — could give ISRO folks enough head start to manoeuvre ‘weaker’ satellites out of harm’s way or prevent catastrophic failures. By virtue of being ISRO’s eyes on the Sun, then, he suggested Aditya L1 was a scientific mission that could also perform some, but not all, of the functions expected of a full-blown early warning system.

(For such a system vis-a-vis solar weather, he said the fourth or the fifth Earth-Sun Lagrange points would have been better stations.)

I’m putting this down here as a public service message. Characterising a scientific mission — which is driven by scientists’ questions, rather than ISRO’s perception of threats or as part of any overarching strategy of the Indian government — as something else is not harmless because it downplays the fact that we have open questions and that we need to spend time and money answering them. It also creates a false narrative about the mission’s purpose that the people who have spent years designing and building the instruments onboard Aditya L1 don’t deserve, and a false impression of how much room the Indian space programme currently has to launch and operate spacecraft that are dedicated to providing early warnings of bad solar weather.

To be fair, the NDTV article says in a few places that Aditya L1 is a scientific mission, as does astrophysicist Somak Raychaudhury in the last paragraph. It’s just not clear why Somanath characterised it as a “protector” and as a “space-based insurance policy”. NDTV also erred by putting “protector” in the headline (based on my experiences at The Wire and The Hindu, most readers of online articles read and share nothing more than the headline). That it was the ISRO chairman who said these things is more harmful: as the person heading India’s nodal space research body, he has a protagonist’s role in making room in the public imagination for the importance and wonders of scientific missions.

While space is hard, there are also different kinds of hardness. For example, on April 15, ISRO issued a press release saying it had successfully tested nozzles made of a carbon-carbon composite that would replace those made of Columbium alloy in the PSLV rocket’s fourth stage and thus increase the rocket’s payload capacity by 15 kg. Just 15 kg!

The successful testing of the C-C nozzle divergent marked a major milestone for ISRO. On March 19, 2024, a 60-second hot test was conducted at the High-Altitude Test (HAT) facility in ISRO Propulsion Complex (IPRC), Mahendragiri, confirming the system’s performance and hardware integrity. Subsequent tests, including a 200-second hot test on April 2, 2024, further validated the nozzle’s capabilities, with temperatures reaching 1216K, matching predictions.

Granted, the PSLV’s cost of launching a single kilogram to low-earth orbit is more than 8 lakh rupees (a very conservative estimate, I reckon) – meaning an additional 15 kg means at least an additional Rs 1.2 crore per launch. But finances alone are not a useful way to evaluate this addition: more payload mass could mean, say, one additional instrument onboard an indigenous spacecraft instead of waiting for a larger rocket to become available or postponing that instrument’s launch to a future mission.

But equally fascinating, and pride- and notice-worthy, to me is the fact that ISRO’s scientists and engineers were able to fine-tune the PSLV to this extent. This isn’t to say I’m surprised they were able to do it at all; on the contrary, it means the feat is as much about the benefits accruing to the rocket, and the Indian space programme by extension, as about R&D advances on the materials science front. It speaks to the oft-underestimated importance of the foundations on which a space programme is built.

Vikram Sarabhai Space Centre … has leveraged advanced materials like Carbon-Carbon (C-C) Composites to create a nozzle divergent that offers exceptional properties. By utilizing processes such as carbonization of green composites, Chemical Vapor Infiltration, and High-Temperature Treatment, it has produced a nozzle with low density, high specific strength, and excellent stiffness, capable of retaining mechanical properties even at elevated temperatures.

A key feature of the C-C nozzle is its special anti-oxidation coating of Silicon Carbide, which extends its operational limits in oxidizing environments. This innovation not only reduces thermally induced stresses but also enhances corrosion resistance, allowing for extended operational temperature limits in hostile environments.

The advances here draw from insights into metallurgy, crystallography, ceramic engineering, composite materials, numerical methods, etc., which in turn stand on the shoulders of people trained well enough in these areas, the educational institutions (and their teachers) that did so, and the schooling system and socio-economic support structures that brought them there. A country needs a lot to go right for achievements like squeezing an extra 15 kg into the payload capacity of an already highly fine-tuned machine to be possible. It’s a bummer that such advances are currently largely vertically restricted, except in the case of the Indian space programme, rather than diffusing freely across sectors.

Other enterprises ought to have these particular advantages ISRO enjoys. Even should one or two rockets fail, a test not work out or a spacecraft go kaput sooner than designed, the PSLV’s new carbon-carbon-composite nozzles stand for the idea that we have everything we need to keep trying, including the opportunity to do better next time. They represent the idea of how advances in one field of research can lead to advances in another, such that each field is no longer held back by the limitations of its starting conditions.
