How do you propose to slow the shuttle down from orbital velocity?


The shuttle does slow from orbital velocity to re-enter.

Yeah, by a tiny fraction of it's total horizontal velocity.

Then there is that inconvenient energy of position which gets
converted to energy of motion as it falls back to Earth.

It slows only slightly, enough to get its orbit to dip into the atmosphere
where it then uses aerodynamic braking. Avoiding the need for
aerodynamic braking was, I believe, the whole point of the original
question.

The short answer to your follow-up question is the Orbital Maneuvering
System. The shuttle uses the OMS for both orbital maneuvering and to slow
from orbital velocity for reentry.

I know how the shuttle de-orbits. My follow-up question was directed at
the OP.

In the context of the original question, the OMS is entirely inadequate.

Of course you do, I just explained it.

It should have been clear to you that he had no idea.

Well, I not surprised that you didn't understand the purpose
of the question.

Have a wonderful New Year.

I certaimly understood what you wrote, if your intent was something else you
misspoke.



Have a wonderful New Year.


Likewise!
