Default Did Apollo do a burn prior to re-entry?

Pat,


At the risk of sounding like a smart aleck, I think the answer is
yes . . . or perhaps more accurately, it depends. It probably
depends on the angle at which the reentry had been attempted, vechicle
velocity, and the weight of the vehicle, which increased as more and
more samples were brought back. I suspect that it would be a funny-
shaped earth orbit, but maybe someone more proficient at orbital
mechanics can tell us for sure.


Take care . . .

I can picture it losing enough velocity that it travels outbound from
the Earth to a very high altitude, stops, and then falls straight into
the atmosphere and burns up.

The heat shield would have withstood 2 additional reentries (skip
+final), but I don't know whether the oxygen whould have run out or
not.
Anyone care to enlighten me regarding O2 supplies on Appolo?

Only good for a couple of extra hours. You really don't want to skip
off the atmosphere. This assumes that the capsule doesn't flip around
and expose the top part to the searing reentry heat.
