BANGALORE: India has successfully launched its first mini space shuttle on Monday as New Delhi's famously frugal space agency joined the global race to make rockets as reusable as airplanes.
The shuttle was reportedly developed on a budget of just INR1 billion, a fraction of the billions of dollars spent by other nations' space programmes.
The Reusable Launch Vehicle (RLV-TD), which is around the size of a minibus, hurtled into a blue sky over southeast India after its 7am lift off.
After reaching an altitude of about 70km, it glided back down to Earth, splashing into the Bay of Bengal 10 minutes later.
The test mission was a small but crucial step towards eventually developing a full-size, reusable version of the shuttle to make space travel easier and cheaper in the future.
"We have successfully accomplished the RLV mission as a technology demonstrator," Indian Space Research Organisation (ISRO) spokesman Devi Prasad Karnik told AFP.
The worldwide race for reuseable rockets intensified after NASA retired its space shuttle programme in 2011.
They are seen as key to cutting costs and waste in the space industry, which currently loses millions of dollars in jettisoned machinery after each launch.
Internet tycoon Elon Musk's SpaceX and Blue Origin of Amazon owner Jeff Bezos have already successfully carried out their own test launches.
Musk told reporters in April that it currently costs about $300,000 to fuel a rocket and about $60 million to build one.
SpaceX first landed its powerful Falcon 9 rocket in December while Blue Origin's New Shepard successfully completed a third launch and vertical landing in April this year.
But ISRO hopes to develop its own version, primarily to cash in on the huge and lucrative demand from other countries to send up their satellites.
Mission to Mars
The Indian space agency is no stranger to stellar achievements on a shoestring budget.
It made global headlines in 2013 after sending an unmanned rocket to orbit Mars at a cost of just $73m. NASA's Maven Mars mission had a $671m price tag.
The launch and its low cost were a source of immense pride in India, which beat rival China in becoming the first Asian country to reach the Red Planet.
K. Sivan, a scientist involved in the latest project, said the seven-metre long shuttle survived the test flight, and scientists hope subsequent models six times as big, to be built over the next decade, will glide safely back to land.
"We have located the place where the vehicle is floating. The landing was soft and the vehicle did not break," Sivan told AFP. "The mission went off as planned and data from the experiment showed that we have achieved its objectives and demonstrated the RLV technology."
Prime Minister Narendra Modi praised the "industrious efforts" of ISRO scientists.
"Dynamism & dedication with which our scientists & @isro have worked over the years is exceptional and very inspiring," Modi said on Twitter.
Modi has often hailed India's budget space technology, quipping in 2014 that a local rocket that launched four foreign satellites into orbit had cost less to make than Hollywood film "Gravity".
