At the end of a public event in Mysore, three young engineers walked up to the chief guest AS Kiran Kumar, chairman of Isro. Rohan Ganapathy and his team had built a prototype of a new propulsion system for satellites and wanted to draw the chairman’s attention towards it. Which they did. A few days later, in late 2015, they got a call from the chairman’s office. The guys surely had the talent to be at the right place at the right time. What followed was no less than a Brobdingnagian step, from India’s space agency towards a little-known startup, Bellatrix Aerospace.

The Isro-Bellatrix association was under wraps until we posed this question: “When will a SpaceX-kind of company come out of India?” The question, of course, implied if Isro was willing to be the anchor tenant for new space startups to grow.

“We have given a developmental contract to a very small company for a propulsion technology which we ourselves have not developed,” said Kiran Kumar. That was an astonishing admission from the head of an agency whose quality is so stringent that it even provides nuts, bolts and washers to its component suppliers.

Satellites need a propulsion system for generating small thrusts to keep them in the orbit. Most of them use chemical propulsion, which means carrying loads of fuel into space and burning it on demand whenever an in-orbit manoeuvre is required. A cheaper and efficient option lies in electric propulsion which Ganapathy and colleagues are now jointly developing with Isro. Instead of carrying heavy fuel, the satellite would rely on its solar panels to generate propulsion.

Why Isro agreed to evaluate an ‘outside’ technology and work with Bellatrix isn’t hard to parse. The space industry is moving towards much smaller satellites. Constellations of such satellites will now fly in formation, which would crucially need electric propulsion. Isro has no time to waste. After almost a decade of dithering on large-scale privatisation, it now has a plan. By 2020, the Indian industry will make a Polar Satellite Launch Vehicle (PSLV), a one-tonne satellite — standard low-earth orbit spacecraft that Isro launches — and several smaller satellites. A  space consortium framework is in place and waiting for the Cabinet approval. The Prime Minister’s Office is “studying” it.

“We are freezing all the mechanism between now and 2020 so that after the first launch of [privately-made] PSLV, the industry quickly ramps up to meet our as well as the market’s demands,” says Kiran Kumar.

The commercial space race in India has just begun.

The exploding opportunity

In 2012-13 when Neha Satak began calling her former professors at the Indian Institute of Science from Texas, she had already founded two space companies in the US but was determined to start one in India. The cost of micro satellites had been falling. The market had opened up due to a surge in university satellites and Satak wanted to make them.

What is The Ken?

The Ken is a subscription-only business journalism website and app that provides coverage across two editions - India and Southeast Asia.

What kind of stories do you write?

We publish sharp, original and reported stories on technology, business and healthcare. Our stories are forward-looking, analytical and directional — supported by data, visualisations and infographics.

We use language and narrative that is accessible to even lay readers. And we optimise for quality over quantity, every single time.

What do I get if I subscribe?

For subscribers of the India edition, we publish a new story every weekday, a premium daily newsletter, Beyond The First Order and a weekly newsletter - The Nutgraf.

For subscribers of the Southeast Asia edition, we publish a new story three days a week and a weekly newsletter, Strait Up.

The annual subscription will get you complete, exclusive access to our archive of previously published stories for your edition, along with access to our subscriber-only mobile apps, our premium comment sections, our newsletter archives and several other gifts and benefits.

Do I need to pay separately for your premium newsletters?

Nope. Paid, premium subscribers of The Ken get our newsletters delivered for free.

Does a subscription to the India edition grant me access to Southeast Asia stories? Or vice-versa?

Afraid not. Each edition is separate with its own subscription plan. The India edition publishes stories focused on India. The Southeast Asia edition is focused on Southeast Asia. We may occasionally cross-publish stories from one edition to the other.

Do you offer an all-access joint subscription for both editions?

Not yet. If you’d like to access both editions, you’ll have to purchase two subscriptions separately - one for India and the other for Southeast Asia.

Do you offer any discounts?

No. We have a zero discounts policy.

Is there a free trial I can opt for?

We don’t offer any trials, but you can sign up for a free account which will give you access to the weekly free story, our archive of free stories and summaries of the paid stories. You can stay on the free account as long as you’d like.

Do you offer refunds?

We allow you to sample our journalism for free before signing up, and after you do, we stand by its quality. But we do not offer refunds.
