The Journey Back to Earth: A Look at the Soyuz Spacecraft's Return

TLDREvery day since November 1998, the International Space Station has orbited the Earth at a speed of 28,000 kmph. When it's time for the crew to return to Earth, a carefully planned and coordinated process begins. The crew undergoes training for the re-entry and prepares the Soyuz spacecraft for undocking. After the undocking, the spacecraft enters the Earth's atmosphere, experiencing extreme temperatures and g-forces. The trajectory is controlled through rotation and adjustments, and the capsule uses a heat shield to protect the crew from the intense heat. Finally, the capsule separates and the Descent module lands safely on Earth.

Q&A

How long does the journey back to Earth take?

The return journey aboard the Soyuz capsule takes approximately 3 and a half hours.

How is the landing site chosen?

The landing site is carefully selected based on the current orbit of the International Space Station and ground conditions.

What happens during the deorbit burn?

The deorbit burn is a 4-minute firing of the main engine to decrease the speed of the spacecraft and change its trajectory.

How is the capsule protected during re-entry?

The capsule is fitted with a protective coating and a heat shield on its base to withstand the extreme temperatures of re-entry.

How is the trajectory of the capsule controlled?

The capsule can adjust its trajectory through rotation and changes in lift, allowing for more flexibility in selecting the landing site.
