ANSWER: Reusable Launch Vehicle
  • The first technology demonstrator of indigenously made Reusable Launch Vehicle (RLV), that can launch satellites into orbit around earth and then re-enter the atmosphere, will be flight tested from Sriharikota in Andhra Pradesh.
  • This will be the first time ISRO will be launching a winged flight vehicle. After launch it will be glided back onto a virtual runway in the Bay of Bengal, some 500 km from the coast. The mission, known as the hypersonic flight experiment, is expected to last about 10 minutes from lift off to splashdown.
  • Reusable Launch Vehicle—Technology Demonstration Programme or RLV–TD is a series of technology demonstration missions that has been conceived by the Indian Space Research Organisation (ISRO) as a first step towards realising a Two Stage To Orbit (TSTO) re-usable launch vehicle.
