Isro works on technology to reuse 1st, 2nd rocket stages
First stage of rocket falling after separation Lift-off from Sriharikota New Delhi: In a bid to cut cost of satellite launchers, Isro is working on reusable launch technology for using the first and second stages of a rocket multiple times. To master the technology, Isro is going to “hold a test on the advanced version of reusable launch vehicle (RLV) in June-July”.
Talking to TOI, Isro chairman K Sivan said, “We are working on a reusable launch technology in order to recover the first and second stages of a Space shuttle injecting a satellite in orbit Vertical landing of first stage
on sea. Will be reused for more launches rocket so that we can reuse them to cut cost and carry heavier payloads. The first rocket stage will be recovered on a vertical landing spot on the sea like Space X has been doing with Falcon rocket. Recovering the second stage is not easy. We are, therefore, developing a winged body like a space shuttle. This shuttle will be attached as a second stage in a rocket. It will carry the top portion of the rocket comprising a satellite to space. Once it injects the satellite in its orbit, the shuttle will return.” He said the “second stage recov- Manoeuvred back to earth with onboard computer controls Landing on an airstrip. Will be reused for future missions ery has never been tried by any other space agency in the world, not even SpaceX”.
Isro had held the first RLV test on May 23, 2016. On the June-July test, Sivan said, “This test will be different where a helicopter will take the shuttle to a considerable height and from that height, the winged body will be dropped. It will glide back to earth and land on an airstrip.” There is speculation the landing strip could be made in Andamans. The third RLV test will be held from the orbit.
