This is Kelsea, Laurie :aka: Serena's daughter. I have a science question.

[Serena]

Does anyone know what Recovery System means?

 

[Dan Murphy]

Hi Kelsea. A recovery system in what context? That is a pretty general term. Pertaining to what?

 

[Serena]

It has to do with a rocket.

The recovery system is how reusable portions of a spacecraft are returned to earth (in the context of the current space shuttle program). The external boosters "recovery system" is a parachute that gently returns the boosters to earth for reuse.

In the "old days" of the Mercury, Gemini, and Apollo programs, the recovery system of parachutes was used to return the capsule containing the astronaut(s) safely to earth.

Well, here are a lot of choices, just using Google to search on that item. Give some of those a look and see if they are of help.

 

[Dan Murphy]

Towncrier's explanation is very good and simple, really answering your question, as to what it is.

Old days??

The recovery system is used to recover the stages of arocket that get jettisoned during takeoff. look here for example

Thank you to everyone who helped.But I think I'll use Towncrier's definition. :jumping4:

 

[Towncrier]

Woohoo!!!

 

[Serena]

Well I need help again. Pnly with what T-time and Gravitational pull mean. Also if you know what N.A.S.A stands for please tell me.

 

[Serena]

I meant only not pnly.

 

[Towncrier]

NASA stands for National Aeronautics and Space Administration. It evolved from NACA, The National Advisory Committee on Aeronautics.

T-time is how time is measured prior to liftoff. When they say T minus 10 minutes, it means that, if all goes according to plans, the launch will take place in 10 minutes. The familiar 10-9-8-7-6-5-4-3-2-1 countdown is just the last few seconds of T time prior to liftoff.

Gravitational pull is the force that two objects exert on each other that attracts them together. The gravitational pull of the Earth is what keeps you from flying off into space.

Thanks Towncrier you rock.
