Subject: [time-nuts] Space mission comes to an end becuase of a "computer time
tagging" problem
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
