13 hour countdown begins(13 hour)

Sriharikota (Andhra Pradesh). The Indian Space Research Organization (ISRO) said on Friday that the 13-hour        (13 hour) countdown for an unmanned flight test has started on Friday, moving towards the ambitious mission of sending Indian astronauts to space. ISRO said that the single-stage liquid propulsion rocket equipped with the ‘crew module’ (which will carry the astronauts) and the crew rescue system will be launched from the first launch pad of Sriharikota Space Center at 8 am on Saturday.

The objective of the test spacecraft mission is to study the safety standards of the crew module and crew rescue system to eventually return Indian astronauts to Earth under the Gaganyaan mission. The Gaganyaan mission aims to send humans into low Earth orbit at an altitude of 400 kilometers in a three-day mission in 2025 and bring them back to Earth safely.

On Saturday, ISRO will attempt the successful launch of its Test Vehicle – Demonstration (TV-D1), a single-stage liquid propulsion rocket. The test vehicle mission with this crew module is an important milestone for the overall Gaganyaan program as almost the entire system has been integrated for the test on Saturday.

ISRO informed on its website on Friday, “The countdown for the launch of TV-D1- test flight at 8 am on October 21 has started at 7 pm on Friday.” ISRO said that the success of this test flight will lay the groundwork for the remaining tests and unmanned missions, which will begin the first Gaganyaan programme.

The ‘crew module’ is the payload in the rocket, and it is a habitable space for astronauts in space with an Earth-like environment. It consists of a pressurized metallic ‘inner structure’ and an unpressurized ‘outer structure’ with ‘thermal protection systems’. During the first test flight on Saturday, data will be obtained to assess the performance of various systems in the ‘Crew Module’ which will help scientists get information about the performance of the vehicle.

The entire test flight program on Saturday is expected to be brief as the ‘Test Vehicle Abort Mission’ (TV-D1) will launch the crew escape system (crew escape system) and crew module at an altitude of 17 km, about 10 km from Sriharikota. Hope to land safely in the sea. Later they will be searched and rescued by the Navy from the Bay of Bengal.
