Genesis crash cause

Excerpt:
"The MIB, analyzing the Genesis capsule at a facility near Denver, said the likely cause was a design error that involves the orientation of gravity-switch devices. The switches sense the braking caused by the high-speed entry into the atmosphere, and then initiate the timing sequence leading to deployment of the craft's drogue parachute and parafoil."
Excerpt 2:
"Each avionics unit contains two g-switches (bottom) used to sense deceleration as the capsule enters the Earth's atmosphere. Investigators report a likely reason Genesis' chutes did not open was a faulty design that had these switches improperly installed on a circuit board."
What was it ? 300 million bucks ? ..

MIB? Men in Black?
That sucks
Though I don't think it was such a good idea to make the parachutes engage via a basic spring? what about a baromoter or something?

Lol @ Mishap, faulty design = mishap... Multi million dollar spacecraft crashing to ground != Mishap.

No one was hurt, so it is correctly described as a mishap.
And 300 million isn't really that much money - unless you personally have to earn it. Someone famous in US government once said, "A Billion here and a Billion there and pretty soon you start talking serious money."
More of a fiasco in my view is the 150 Million or so spent on the "secure low pressure" facility designed to recieve the Genesis contents. There were concerns (a la Andromeda Strain) that particles collected in space might pose some hazard here on earth. Guess THAT money was kinda wasted.
As it turns out, the Genesis probe looks like it'll yield some usable data - so the mission wasn't a total washout.
Let's not forget some rather more spectacular failures: Mars Polar Lander (Feet instead of Meters), Space Shuttle Challenger (Launching in sub-zero temperatures), Space Shuttle Columbia (ET insulation failure), Apollo 1 (Fire enhanced by pure Oxygen atmosphere, no quick exit available).
These are the worst failures. Believe me, there'll be more - and worse failures too. I predict that by 2050 there'll have been 500 people die in space, or in the pursuit of space.
This will pale into nothingness when put against the number of people who died opening up The Wild West though.

$300 Million, and these guys cant properly wire a sensor to a PCB?!?!?!
ROTFLMAO!!

i hope so. i hope we get to the point where people are dying in space from car-carshes, and heart attacks caused by roadrage.
when space travel gets THAT common, things'll be sweet.
