ISRO carries out tests for Crew Escape system as part of human space flight

Chennai: As part of its bid to send Indian astronauts into space, Indian Space Research Organisation (ISRO) on Thursday carried out Pad Abort Test (PAT), a major technology demonstration to ensure safe recovery of the crew module in case of any exigency at the spaceport of Sriharikota, about 80 km from here. An ISRO release here said the 259 second test was the first in a series of tests to qualify a Crew Escape System, which is a critical technology relevant for human spaceflight. 'The Crew Escape System is an emergency escape measure designed to quickly pull the crew module along with the astronauts to a safe distance from the launch vehicle in the event of a launch abort', it said. The first test (Pad Abort Test) demonstrated the safe recovery of the crew module in case of any exigency at the launch pad.

After a smooth five hour countdown, the Crew Escape System, along with the simulated crew module with a mass of 12.6 tonnes, lifted off at 0700 hrs at the opening of the launch window from its pad at Satish Dhawan Space Centre, Sriharikota. The test was over in 259 seconds, during which the Crew Escape System along with crew module soared skyward, then arced out over the Bay of Bengal and floated back to earth under its parachutes about 2.9 km from Sriharikota. The crew module reached an altitude of nearly 2.7 km under the power of its seven specifically designed quick acting solid motors to take away the crew module to a safe distance without exceeding the safe g-levels. Nearly 300 sensors recorded various mission performance parameters during the test flight. Three recovery boats were being exercised to retrieve the module as part of the recovery protocol, the release said.
