Isro’s Pushpak nails landing after being dropped by Chinook
NEW DELHI, MAR 22 : The Indian Space Research Organisation (Isro) on Friday successfully carried out the landing mission of its Reusable Launch Vehicle (RLV) named ‘Pushpak’ from the Aeronautical Test Range (ATR) in Challakere near Karnataka’s Chitradurga. Isro chairman S Somanath and other senior officials were present at the launch site.
“Isro nails it again! Pushpak (RLV-TD), the winged vehicle, landed autonomously with precision on the runway after being released from an off-nominal position,” the space organisation wrote on X.
The launch of Pushpak is India’s bold attempt towards making space access more affordable and sustainable.
“Pushpak was lifted by an Indian Airforce Chinook helicopter and was released from 4.5 km altitude. After release at a distance of 4 km from the runway, Pushpak autonomously approached the runway along with cross-range corrections. It landed precisely on the runway and came to a halt using its brake parachute, landing gear brakes and nose wheel steering system,” the Isro said.
The Pushpak RLV is designed as an all-rocket, fully reusable single-stage-to-orbit (SSTO) vehicle, incorporating several major elements such as the X-33 advanced technology demonstrator, the X-34 testbed technology demonstrator, and the upgraded DC-XA flight demonstrator.
The launch marks the third flight of Pushpak, following a series of tests aimed at perfecting its robotic landing capabilities under increasingly complex conditions.
The project, which has been in development for over a decade, previously saw a successful test in April last year, where the vehicle demonstrated an autonomous landing after being released from an Indian Air Force Chinook helicopter. This marked a critical milestone for the Pushpak RLV, bringing it closer to achieving orbital re-entry capabilities.
Named after the mythical ‘Pushpak Viman’ from the Ramayana, Isro’s modern-day aircraft symbolises prosperity and innovation.
The winged technology demonstrator RLV has been configured to act as a flying test bed to evaluate various technologies, namely, hypersonic flight, autonomous landing and powered cruise flight.
With an investment exceeding Rs 100 crore, the project not only showcases India’s technological prowess but also sets the stage for future endeavours, including the ambitious goal of establishing the Bhartiya Antariksha Station by 2035.
During his visit to the Vikram Sarabhai Space Centre last month, Prime Minister Narendra Modi was briefed by Somanath about the development of the vehicle.
In January 2012, Isro’s design of the RLV spacecraft was approved by the National Review Committee. After the clearance was given, the first prototype was built and christened as the RLV-TD (Technology Demonstrator).
With advanced supercomputer simulations and the development of heat-resistant materials for protecting the spacecraft from high temperatures during atmospheric re-entry by the National Aerospace Laboratory and the Defence Research and Development Organisation (DRDO), RLV went for its maiden flight in 2016.
