NASA's Deep Space Comet Hunter Mission Comes to an end
The news release includes this paragraph:
"After losing contact with the spacecraft last month, mission
controllers spent several weeks trying to uplink commands to reactivate its
onboard systems. Although the exact cause of the loss is not known,
analysis has
uncovered a potential problem with computer time tagging that could have led
to loss of control for Deep Impact's orientation. That would then affect
the positioning of its radio antennas, making communication difficult, as
well as its solar arrays, which would in turn prevent the spacecraft from
getting power and allow cold temperatures to ruin onboard equipment,
essentially freezing its battery and propulsion systems."
Knowing the membership of this group, does anyone have more insight into
what the "computer time tagging" problem might be?
Thanks,
David
