Discovery Starts Her Return Home by bruey on 6 August 2005 2:31pm
 
Just to let you all know, well those of you that have been following the Return To Flight mission that Discovery unlocks from the International Space Station today and begins her return to Earth, she is scheduled to land at Kennedy Space Centre on Monday at 3.46pm CDT. I hope that you will join me in wishing Commander Eileen Collins and the crew good luck and godspeed for a safe return home.

How The Shuttle Returns To Earth

To return to Earth the space shuttle must make a series of complicated manouevres to align itself into the correct position to achieve a safe descent.
1. The shuttle flies upside down in orbit to control its heating.
2. To re-enter the atmosphere, the shuttle is turned tail first to the direction of travel, and fires its engines to slow its speed.
3. The orbiter is then flipped the right way up and enters the top layer of the atmosphere at about a 40-degree angle from horizontal with its wings level.


4. The orientation keeps its black thermal tiles facing the majority of the heat - as high 1,650C (3,000F) on the leading edges of the wings and nose.
5. As its speed drops, the shuttle starts to fly more like an aircraft, using its rudder and wing flaps for control. It banks sharply to slow its speed still further
6. The shuttle falls from a height of more than 360km at speeds that top Mach 30, and at an angle of 19 degrees, far steeper than that of a commercial aircraft. The spacecraft comes to a dead stop half a world a way from where it began the descent.

Thought I'd post this info from the BBC News Website to give you an idea of how dangerous re-entry is.
