‘ISRO’s Chandrayaan-2 mission to cost lesser than Hollywood movie Interstellar – here’s how they make it cost-effective’, staff, Moneycontrol, February 20, 2018. ∞
‘Chandrayaan-2 mission cheaper than Hollywood film Interstellar’, Surendra Singh, Times of India, February 20, 2018. ∞
The following statements from the Moneycontrol and Times of India articles have no meaning:
- The cost of ISRO’s Mars Orbiter Mission was less than the production cost of the film Gravity.
- The cost of ISRO’s Chandrayaan 2 mission is expected to be less than the production cost of the film Interstellar.
It’s like saying the angular momentum of a frog is lower than the speed of light. “But of course,” you’re going to say, “we’re comparing angular momentum to speed – they have different dimensions”. Well, the production cost of a film and mission costs also have different dimensions if you cared to look beyond the ‘$’ prefix. That’s because you can’t just pick up two dollar figures, decide which one’s lower and feel good about that without any social and economic context.
For example, what explains the choice of films to compare mission costs to? Is it because Gravity and Interstellar were both set in space? Is it because both films are fairly famous? Is it also because both films were released recently? Or is it because they offered convenient numbers? It’s probably the last one because there’s no reason otherwise to have picked these two films over, say, After Earth, Elysium, The Martian, Independence Day: Resurgence or Alien: Covenant – all of which were set in space AND cost less to make than Interstellar.
So I suspect it would be equally fair to say that the cost of C’yaan 2 is more than the budget of After Earth, Elysium, The Martian, Independence Day: Resurgence or Alien: Covenant. But few are going to spin it like this because of two reasons:
- The cost of anything has to be a rational, positive number, so saying cost(Y) is less than cost(X) would imply that cost(X) > cost(Y) ≥ 0; however, saying cost(Y) is greater than cost(X) doesn’t give us any real sense of what cost(Y) could be because it could approach ∞ or…
- Make cost (Y) feel like it’s gigantic, often because your reader assumes cost(Y) should be compared to cost(X) simply because you’ve done so
Now, what comparing C’yaan 2’s cost to that of making Interstellar achieves very well is a sense of the magnitude of the number involved. It’s an excellent associative mnemonic that will likely ensure you don’t forget how much C’yaan 2 cost – except you’d also have to know how much Interstellar cost. Without this bit of the statement, you have one equation and two variables, a.k.a. an unsolvable problem.
Additionally, journalists don’t use such comparisons in other beats. For example, when the Union budget was announced on February 1 this year, nobody was comparing anything to the production costs of assets that had a high cultural cachet. Rs 12.5 crore was Rs 12.5 crore; it was not framed as “India spends less on annual scholarships for students with disabilities than it cost to make Kabali“.
This suggests that such comparisons are reserved by some journalists for matters of space, which in turn raises the possibility that those journalists, and their bosses, organisations and readers, are prompted to think of costs in the space sector as something that must always be brought down. This is where this belief becomes pernicious: it assumes a life of its own. It shouldn’t. Lowering costs becomes a priority only after scientists and engineers have checked tens, possibly hundreds, of other boxes. Using only dollar figures to represent this effort mischaracterises it as simply being an exercise in cost reduction.
So, (risking repetition:) comparing a mission cost to a movie budget tells us absolutely nothing of meaning or value. Thanks to how Moneycontrol’s phrased it, all I know now is that C’yaan 2 is going to cost less than $165 million to make. Why not just say that and walk away? (While one could compare $165 million to mission costs at other space agencies, ISRO chief K. Sivan has advised against it; if one wants to compare it to other PSUs in India, I would advise against it.) The need to bring Interstellar into this, of course, is because we’ve got to show up the West.
And once we’re done showing up the West, we still have to keep. Showing up. The West. Because we’re obsessed with what white people do in first-world countries. If we didn’t have them to show up, who knows, we’d have framed ISRO news differently already because we’d have been able to see $165 million for what it is: a dimensionless number beyond the ‘$’ prefix. Without any other details about C’yaan 2 itself, it’s pretty fucking meaningless.
Please don’t celebrate frugality. It’s an unbecoming tag for any space programme. ISRO may have been successful in keeping costs down but, in the long run, the numbers will definitely go up. Frugality is a harmful aspiration vis-à-vis a sector banking on reliability and redundancy. And for fuck’s sake, never compare: the act of it creates just the wrong ideas about what space agencies are doing, what they’re supposed to be doing and how they’re doing it. For example, consider Sivan’s answer when asked by a Times of India reporter as to how ISRO kept its costs down:
Simplifying the system, miniaturising the complex big system, strict quality control and maximising output from a product, make the missions of Indian space agency cost-effective. We keep strict vigil on each and every stage of development of a spacecraft or a rocket and, therefore, we are able to avoid wastage of products, which helps us minimise the mission cost.
If I didn’t know Sivan was saying this, I’d have thought it was techno-managerial babble from Dilbert (maybe with the exception of QC). More importantly, Sivan doesn’t say here what ISRO is doing differently from other space agencies (such as, say, accessing cheaper labour), which is what would matter when you’re rearing to go “neener neener” at NASA/ESA, but sticks to talking about what everyone already does. Do you think NASA and ESA waste products? Do they not remain vigilant during each and every stage of development? Do they not have robust QC standards and enforcement regimes?
Notice here that Sivan isn’t saying “we’re doing it cheaper than others”, only that doing these things keeps the space agency “cost-effective”. Cost-effective is not the same as frugal.

One response to “For space, frugality is a harmful aspiration”
This is a really good piece. I’m embarrassed to admit that, following those headlines, I, too, have made comments about India’s Mars mission costing lesser than Gravity.
I’ve always been cognizant of the fact that cheaper salaries have played an important role in keeping ISRO’s mission costs down. Secondly, I don’t take undue pride in the fact that India was the first country to reach Mars on the first attempt. The very fact that other countries have tried, failed, and succeeded gives us enough information about what mistakes to avoid and allows us to duplicate what they got right. The second person to create the light bulb cannot really brag about how he got it right on his first attempt while positively comparing himself to Edison who took 99 attempts to do the same. Edison’s failures illuminate the path for subsequent inventors to walk on.
None of this is to take away from India’s mission success. I’m actually quite proud of it. It’s just the jingoistic pride that irks me–both in others and, sometimes unbeknownst to me, in myself.
