ISRO’s LVM3 M3/ OneWeb India-2 Mission

LVM3 M3/ OneWeb India-2 Mission was successfully launched on 26 March 2023. In its sixth consecutive successful flight of LVM3, the vehicle placed 36 satellites belonging to the OneWeb Group Company in their intended 450 km circular orbit with an inclination of 87.4 degrees.

The vehicle took off with a total payload of 5,805 kg at 09:00:20 hours IST from the second launch pad at SDSC-SHAR, Sriharikota. It achieved satellite injection conditions in about 17 minutes and began injecting the satellites from the twentieth minute. The vehicle performed a sophisticated manoeuvre to orient in orthogonal directions and injected the satellites into precise orbits with defined time-gaps to avoid collision of the satellites.









Godrej Aerospace contributes to ISRO's heaviest rocket LVM3

Godrej Aerospace, a business unit of Godrej & Boyce, the flagship company of the Godrej Group, has contributed to the LVM3 (Launch Vehicle Mark III), ISRO's heaviest launcher till date. For this mission, the L110 engine for the core stage and the CE20 engine thrust chamber for the upper stage have been made by Godrej Aerospace. With a steadfast dedication to indigenous manufacturing for India's space endeavours, Godrej Aerospace has contributed to all PSLV and GSLV launches in the country and has delivered over 175 engines and other critical equipment till date.


ISRO conducts Rail Track Rocket Sled deployment tests

ISRO conducted the Rail Track Rocket Sled deployment tests of the Gaganyaan Pilot and Apex Cover Separation (ACS) parachutes in cluster configurations at the Terminal Ballistics Research Laboratory (TBRL), Chandigarh, in March 2023. The first test simulated the clustered deployment of two pilot parachutes. One parachute was subjected to a minimum angle with respect to flow conditions and the second parachute was subjected to a maximum angle with respect to flow. These pilot parachutes are used in the Gaganyaan mission to extract and deploy the main parachutes independently.

The second test simulated the clustered deployment of two ACS parachutes under maximum dynamic pressure conditions. The test also simulated clustered deployment at a 90-degree angle of attack conditions for the crew module. The ACS parachutes are used in the Gaganyaan mission for the separation of the apex cover mounted on the Crew Module. Both pilot and ACS parachutes were deployed using a pyrotechnic mortar device.

The Gaganyaan parachute system development has been a joint effort by VSSC, Thiruvananthapuram and Aerial Delivery Research and Development Establishment (ADRDE), Agra.




 

Chandrayaan-3 undergoes Integrated Module Dynamic Tests

Chandrayaan-3 spacecraft successfully completed the essential tests that validated its capability to withstand the harsh vibration and acoustic environment that the spacecraft would face during its launch. These tests were conducted during the first week of March 2023 at the test facilities located at the UR Rao Satellite Centre in Bengaluru. These tests are an essential part of the qualification and acceptance process for any spacecraft. These tests were particularly challenging, considering the fact that the Chandrayaan-3 spacecraft is a composite of three modules viz. Propulsion Module, Lander Module and the Rover module.
