Space Shuttle.

Think of it this way. The shuttle isn't moving fast, its landing on a
fast moving object. Landing on the earth is like a carrier landing,
the earth is spinning around and the shuttle has to match to it.

That makes sense! Thanks!

The upshot, to a pilot, is that space objects cannot do "slow flight."

What about when they let John Glen ride a couple years ago? I heard they
wouldn't let him drive because they were concened that he would end up
orbiting the earth at 25 miles per hour with the turn signals on...

And they had the engine igniters wired to a "Clapper".... :-)

As long as were on the subject of getting into and out of orbit,
anyone want to discuss the space elevator concept?

What is going to be used as the counter-mass in space?
Is someone going to trap the proper sized rock in the asteroid belt
and haul it back to the desired Earth orbit to attach to the top of
the elevator tube?


We could use anthony. We'd have to check as to his exact mass, but I
bet it's in the ballpark.

Mass (definition) - anything that has weight and takes up space.

While Anthony does take up space in these forums, I think most would
agree that what he writes carries no weight.


I was thinking more of the pile of Krispy Kreme boxes in the corner of his
bedrom and where their contents have gone.

Yes potential energy becomes kinetic energy and that is taken care of
by friction during reentry.

And thus we have come full circle and forgotten the original question,
which was why does the shuttle have to land so fast.

We are certainly getting better at dragging discussions off topic. In the
old days it used to take as much as a hundred posts to come full circle, but
today we can accomplish it in as little as dozen or so.

People that live in reality have things like "speed dating", here we are
limited to things like "speed drifting".

The original question was answered way back earlier in the thread.

Yes it was, and the above is part of the answer.

As I said, we have come full circle.
