BENGALURU - The start-up behind India’s first private space launch plans to put a satellite into orbit in 2023 and expects to be able to do so at half the cost of established aerospace companies.

The Hyderabad-based company, backed by Singapore’s sovereign wealth fund GIC, says the US$68 million (S$93 million) it has raised will fund its next two launches. Skyroot has been in contact with more than 400 potential customers.

Thousands of small satellite launches are planned in the coming years, as companies build out networks to deliver broadband services like SpaceX’s Starlink and to power applications like tracking supply chains or monitoring offshore oil rigs.

Skyroot faces both established and up-and-coming rocket launch rivals that also promise to bring down costs. In China, startup Galactic Energy put five satellites into orbit last week in its fourth successful launch.

In Japan, Space One, backed by Canon Electronics and IHI, plans to launch 20 small rockets per year by the middle of the decade.

But Skyroot, which launched a test rocket last week, expects to cut the cost of a launch by 50 per cent compared with current pricing for established competitors like billionaire Richard Branson’s Virgin Orbit and California-based Rocket Lab USA.

Mr Pawan Chandana, one of Skyroot’s two co-founders, told Reuters he expected a surge in demand for the company’s launch services if it proves itself with launches set for 2023.

“Most of these customers have been building constellations and will be launching them in the next five years,” he said.

The Modi government’s push to increase India’s share of the global space launch market from just 1 per cent has given investors confidence that Skyroot and other startups have government backing for their efforts, Skyroot says.

“Three or four months back, when we were talking to investors, one of the biggest questions they asked was if the government was supporting us,” Skyroot co-founder Bharath Daka told Reuters.

India opened the door to private space companies in 2020 with a regulatory overhaul and a new agency to boost private-sector launches.

Before that, companies could only act as contractors to the Indian Space Research Organisation (Isro), a government space agency with a reputation of its own for frugal engineering. The country’s Mars mission in 2014 cost only US$74 million, less than the budget of the Hollywood space movie Gravity.

Building on India’s record for cost efficiency will be key, said Mr Chandana. Skyroot, founded in 2018 when Mr Chandana and Mr Daka quit jobs at Isro, has set a target to develop rockets for one-fifth of the current industry costs.

The Skyroot rocket that reached an altitude of 89.5km in last week’s test launch used carbon-fibre components and 3D-printed parts, including the thrusters. That boosted efficiency by 30 per cent, cutting weight and procurement costs. But it meant Skryoot engineers had to write the machine code for vendors who fabricated the rocket because few had experience working with carbon fibre.

With 3D printing, Skyroot believes it can build a new rocket in just two days as it works towards reusable rockets, a technology pioneered by SpaceX.

Mr Chandana and Mr Daka believe the per-kilogramme launch cost for a satellite can be brought down to nearly US$10, from thousands of dollars currently, a stretch target that could upend the economics of space commerce and one that draws inspiration from their idol: Mr Elon Musk.

“SpaceX is a symbol of great innovation and great market validation,” said Mr Chandana, who added they have not had the chance to speak to Mr Musk.

“Right now, we think he’s probably busy running Twitter.” REUTERS
