Genesis Crash Proves We Need to Keep Hubble

The recent crash of the Genesis spacecraft should serve as a clear
warning to NASA administrators who favor allowing Hubble to fall to
Earth while only promising to replace the existing orbital observatory
with a larger, better one which has yet to see first light.

Murphy, who coined the phrase, "If something can go wrong, it will",
should be adopted as the patron saint of engineers and planners everywhere.
There should be a shrine to him in every hallway of NASA, lest they forget
their recent failures - Galileo, numerous Mars craft, and now Genesis.

Cheers,
Larry G.

Poor logic. You could equally well conclude we should never fly any
mission which depends on deployment of a parachute.

Plus I think the plan is to not "allow Hubble to fall to Earth": Major
budget for safe disposal.

I think it is a clear warning to MAKE THE **** SURE ALL CRITICAL SYSTEMS
LIKE A GODAMN BATTERY
WON'T FAIL...it just keeps going and going and going....

And precisely how are you going to guarantee 100% reliability? Every
space-faring organization has utilized reentry parachutes for decades,
and even mid-air retrieval is a proven technique.

Batteries fail. New batteries, fresh out of the box, fail. Batteries
subjected to space for two years fail.

Please describe how it can be predicted whether a particular battery,
indistinguishable from all the others in all respects, will fail when
the others from the same batch will not.

"Cheers?" What's so "cheery" about that??

You've been watching too many bunny commercials: Nothing keeps "going
and going and going ...."

OTOH -- it would be nice to have it start "going", which the parachute
did not.

It's exploration, and in exploration things go wrong.

That's never changed.

It's in every history book you pick up, those at the front of the line
usually pay the price of trying something for the first time, if the
toll keeper happens to be collecting that day.

That battery system will go through a complete redesign, and the next
one won't fail.

Genesis and it's accomplishments aren't about the last minute of the
flight exclusively, look at what it did, and that it made it home, a
battery failing to detonate a charge to deploy the drogue is hardly a
failure of a program.

Oh, and Spirit and Opportunity are, in and of themselves, enough to
justify every systems failure it took to get them there.

IMHO, NASA has never looked better than they do now......simply amazing
people, with some incredible opportunities for exploration, failure, and
success in the coming years.

Fantastic!
