7 minute blackout, 1600 degree temperature … Moment where Sunita Williams’ Dragon Capsules crossed the danger like Kalpana Chawla – Sunita Williams Return Spacex Dragon Capsule Splashdown Nasdown Nasa Kalpaana Chawla Spacecraft Temrature NTC

Sunita Williams has returned to the earth safely after spending nine months in space. The Dragon capsule of SpaceX was landed in the sea of ​​Florida with the four astronauts, including SpaceX’s Dragon Capsule Sunita. This journey from space to earth was 17 hours. But in this process of landing, there was also a moment of 7 minutes to stop breathing.

The journey of 17 hours from the International Space Station (ISS) to the Earth was full of challenges. But as soon as the spacecraft entered the Earth’s atmosphere, its temperature was more than 1600 degrees Celsius. This was the time when for seven minutes Communication Blackout Done. However, this is normal but a challenging phase. During this time, NASA does not contact the spacecraft.

The same happened with SpaceX’s dragon. However, seven minutes later, the contact with the spacecraft was restored again at around 3.20 am on Wednesday. But this seven -minute blackout time is very decisive for any spacecraft entering the Earth’s atmosphere. During this period, the chances of cushion of spacecraft are increased due to the temperature being much higher than normal. On February 1, 2003, the accident occurred with NASA’s spacecraft Colombia, when the spacecraft crashed as soon as the Earth entered the Earth’s atmosphere, in which Kalpana Chawla became a victim of an accident. In such a situation, this time is very careful for any spacecraft.

What is communication blackout?

Whenever a spacecraft enters the Earth’s atmosphere from the space, its speed is about 28000 km per hour. When the capsule passes at this speed, it eats the atmosphere. Due to this friction, the temperature of the capsule increases further, causing the spacecraft crash. During this time, the signal of the spacecraft is broken by mission control. Meanwhile, there is no contact of the vehicle in any way.

Crossing this challenge, the spacecraft had a successful landing in the sea and one by one the four astronauts were taken out safely. In this way, after spending 286 days in space, Sunita Williams and her companions breathed in the fresh air of the earth once again.
