Direct uses quite a bit of fuel also.
We did use a little fuel t hat one day.
We were
doing so many experiments in a row that we had to
very rapidly get the spacecraft back to a zero­
zero- zero or a pitch down 30 posi tion.
When you
track one of these targets and come through the
nadir and keep on going, boy, you're really smoking
towards a rearward direction.
You're sitti ng i nverted BEF.
That's r i ght, you ' ve got rates built up going away
from you and you 'd have to use Direct to stop those
rates, get yourself moved all the way back up here
and stop them again.
Maybe it'd be so tight that
you'd use Di rect to get down and start on it, and
then switch to Pulse and track in Pul se and then
r i ght back up and start doing something else. Well,
we di d eat up a lot of fuel that day, but we got
everything done that day.
We hit darned near all
targets.
Di rect i s a real responsive , real fine way to
maneuver.
