[Az-Geocaching] NASA in mourning

[Jim Scotti]

Yeah, that darn chute - but it was not the chute itself - it apparently never
left the spacecraft, which means it was something else, the pyrotechnic
charge, the circuitry that should have fired that charge (which normally is
multiply redundant....), the sensor that detects the G load of entry and
triggers timers that sequence events, or even the battery.  Lots of things to
look at, and luckily, the spacecraft is there to be looked it.  We need to
find out the root cause of this failure so we can be sure we don't have
similar problems in Stardust which will return samples of a comet in January
2006, or if we need to improve the design before building other missions with
similar equipment.  The chute may be minor, but it is one of the many things
that has to work!
