The RLV-TD vehicle is 6.5m long and weighs 1750kg. Nasa’s retired space shuttle, which could carry seven astronauts and cargo into space, was 37.2m long.The RLV-TD vehicle is 6.5m long and weighs 1750kg.

Isro’s aim is to fly a series of test flights to develop an uncrewed, reusable vehicle for cheap, regular access to space. They estimate that a successful spaceplane could lower the cost to orbit by a factor of 10.Isro’s aim is to fly a series of test flights to develop an uncrewed, reusable vehicle for cheap, regular access to space.

This first test flight took place on an HS9 solid rocket booster and boosted the spaceplane to an altitude of 65km. As it fell back to Earth, the RLV-TD encountered the atmosphere at five times the speed of sound. This verified the thermal protection system that was developed to protect the craft from the fiery re-entry.This first test flight took place on an HS9 solid rocket booster and boosted the spaceplane to an altitude of 65km.

Other on-board systems tested during the descent included the autonomous navigation, guidance and control systems. All worked well, but instead of landing on a runway, the spaceplane splashed as planned down into the Bay of Bengal. As expected, the impact destroyed the craft.Other on-board systems tested during the descent included the autonomous navigation, guidance and control systems.

India now plans to build a runway near Sriharikota so that the test programme can return vehicles intact.India now plans to build a runway near Sriharikota so that the test programme can return vehicles intact.
