Someone from NASA posted that there were very significant mass margins
on the HST re-boost mission.  A while back i had asked why not carry
the EDO pallet up,  and the answer was the mass margins were tight enough, they weren't even carrying extra suits.

|Pat, this would be slower, more expensive and worse.

Where's wingo when you need him:-)

COme on.   Knock that S**T off.

YOu forget,  that during skylab,  they did  overnight mission planning
for the repair EVA's.   Also during the
