Shubhanshu Shukla and team with him.
Indian astronaut Shubhanshu Shukla is returning to Earth today after spending 18 days in ISS. Shubhanshu Shukla and his team are riding in the dragon spacecraft. The spacecraft will travel for about 23 hours and splashdown at the sea near the coast of California at 3.1 pm this afternoon. At the time when the spacecraft enters the Earth’s atmosphere, its temperature can reach 1600 ° C. After this, parachutes will open in two stages. First at a height of 5.7 kilometers, stabilizing shoots and then the main parachutes will open at about two km, which will make it possible to have a safe landing of spacecraft.
How will D-Arbit Burn Process
The spacecraft of Shubhanshu is moving towards the Earth at a speed of 28 thousand kilometers per hour. In such a situation, the largest challenge is the D-Arbit Burn Process performed 54 minutes before the splashouown of the spacecraft. Indeed, as soon as the spacecraft enters the Earth’s atmosphere, the high speed of the spacecraft and the air present in the atmosphere occur at that time. In such a situation, the temperature reaches more than 1600 ° C and the trunk present in the dragon spacecraft starts burning, which looks like a fireball. During this time the speed of spacecraft is reduced through the thruster. This process is called ‘de-arbit burn’. Its speed is reduced to 24 kilometers per hour. During this time, the astronauts present in the spacecraft are wearing space shoots and the temperature of the capsule in which they are sitting is only 29 to 30 degrees.
What time will be done
The entire process ranging from D-orbit burn to Splashdown is already determined. For example, 54 minutes before Splashdown i.e. at 02 pm 7 minutes, there will be a de-arbitor. After that, the trunk part will be separated at 02 to 26 minutes in the afternoon. After 4 minutes, that is, nozcon will be closed at 02:30 in the afternoon and when the height of 6 kilometers will be saved from the Earth i.e. at 02:00 pm, stabilizing shoots will open. After one minute, the main parachute will open at 02 pm at 58 pm, after which the capsule will be stabilized and at 3.15 pm, there will be splendarsland of capsules in the sea on the California coast at 3:1 1 in the afternoon.
Spacecraft will land in the sea
Actually, the parachutes in the capsule reduce the speed of the capsule. This speed decreases to 24 km per hour. At this speed, the capsule descends into the sea. This process is called Splashdown. As soon as the capsule descends into the sea, astronauts sit inside the capsule, but the ground teams already in the sea reach the capsules with the help of a large boat. Then the capsules are taken out of the sea and the nose of the capsule is opened, then the astronauts sitting in it are taken out. He is then taken to the isolation center.
