ISRO’S RLV LEX Reusable Launch Vehicle Mission
ISRO’S RLV LEX Reusable Launch Vehicle Mission
ISRO, the Indian Space Research Organization, successfully completed the landing experiment for the Reusable Launch Vehicle-Technology Demonstration (RLV-TD) programme.
ISRO has accomplished the Reusable Launch Vehicle Autonomous Landing Mission (RLV LEX) at the Aeronautical Test Range (ATR) in Chitradurga, Karnataka. The RLV was flown to a height of 4.5 kilometres in an underslung cargo by an Indian Air Force Chinook chopper. The RLV was automatically released 4.6 km downrange once the predetermined pillbox conditions were met. Using the Integrated Navigation, Guidance & Control system, the RLV then conducted approach and landing manoeuvres with success and independently landed on the ATR air strip. By this achievement, ISRO has successfully autonomously landed a spacecraft.
- The test involved a winged body lifted to an altitude of 4.5 km by an Indian Air Force (IAF) Chinook helicopter, subsequently freed to execute an independent high-speed (350 kmph) landing on a runway, and achieved the landing parameters.
- This is the first time that a winged body has been released mid-air by a helicopter and carried out an autonomous landing.
Remember: In addition to ISRO, the IAF, the Centre for Military Airworthiness and Certification (CEMILAC), the Aeronautical Development Establishment (ADE), and the Aerial Delivery Research and Development Establishment (ADRDE) all contributed to this test.
Important Points:
- RLV LEX is essentially a spacecraft with a low lift-to-drag ratio that needed a high glide angle approach and a high landing speed of 350 kilometres per hour.
- LEX made use of several indigenous systems. ISRO created localised navigation systems based on instrumentation, sensor systems, and pseudolite systems, among other things.
- Using a Digital Elevation Model (DEM) of the landing site, the Ka-band Radar Altimeter produced accurate altitude data. Native landing gear, aerofoil honeycomb fins, and braking parachute system and NavIC receiver.

Frequently Asked Questions:
What is RLV TD launched by ISRO?
Reusable Launch Vehicle Autonomous Landing Mission (RLV LEX) ISRO successfully conducted the Reusable Launch Vehicle Autonomous Landing Mission (RLV LEX). The test was conducted at the Aeronautical Test Range (ATR), Chitradurga, Karnataka in the early hours on April 2, 2023.
What is the use of RLV-TD?
The RLV-TD will be used to develop technologies like hypersonic flight (HEX), autonomous landing (LEX), return flight experiment (REX), powered cruise flight, and Scramjet Propulsion Experiment (SPEX).
Who launched the first reusable spacecraft?
NASA – Shuttle Basics. The Space Shuttle is the world’s first reusable spacecraft, and the first spacecraft in history that can carry large satellites both to and from orbit.
