I love this quote:
Quote:
Bill Gerstenmaier, NASA chief of space flight operations, said late
today he's optimistic the Russians will resolve the reboost issue.
Similar problems have developed in previous reboost maneuvers, he
said, and the Russians managed to recover.
"There is pretty complex software and commanding that's associated
with those Progress burns and typically we'll find something there
that was out of configuration that cut that burn a little bit short,"
Gerstenmaier said.

Quote: Gerst says the Russians can try again on Friday.
What is/are the reason(s) for them waiting a few days instead of trying 90
minutes later when the ISS is in the same orbital period ?
Is it just to have time to investigate the problem, or are there mechanical
requirements or orbital physics issues that requir such a time period
between two firings ? |
