Satellite Tip-Over Mishap Due to Missing Bolts 76
cradle writes "On September 6th, the $239 Million Dollar NOAA N-Prime Satellite toppled over and crashed to the floor of Lockheed Martin Space Systems' factory in Sunnyvale, CA, as it was being repositioned to replace an instrument. Today NASA released their report on the cause of the accident. It seems somebody forgot to check whether it was bolted down: '... during an operation that required repositioning (rotating) the
TIROS NOAA N-PRIME spacecraft from a vertical to a horizontal position, the spacecraft
slipped from the Turn-Over Cart (TOC) and fell to the floor. The spacecraft fell because the
TIROS adapter plate to which it was mounted was not bolted to the TOC adapter plate with the
required 24 bolts. The bolts were removed from the TOC by another project while the cart was
in a common staging area, an activity which was not communicated to the NOAA project team.'"
So... what they said originally? (Score:5, Interesting)

I can only imagine the multiplicative factor involved when it's a $240M satellite instead of a $20K prototype.
As for why they took a year to report out on the cause...the thing cost 240 million frickin' dollars! I'm sure the managers wanted more of an answer as to why it's in pieces on the ground than "Uh...we dropped it". Maybe they wanted to know "why it was dropped" and "how it was dropped" and "what is the likelyhood that a thing will be dropped again" and "where does that tech who dropped it live?"

They had used the TOC a few days prior, and there was no documentation that the bolts had been removed, so they assumed that it was fine. If some that other project team hadn't forgotten the documentation this wouldnt've happened.
