96 Flights. I worked STS-26 through STS-122. There is a framed STS-48 mission chart hanging on the wall above my desk as I type. The only satellite I remember us literally losing was the Italian tethered satellite. I've got a piece of the tether hanging on the wall at the office. There was plenty of that to hand out. I think there was 12 or 13 miles of it left on the real when the tether broke.
Tethered Satellite? I was asked to be on that ... and I bailed after a few days ... accident waiting to happen unfortunately (on the contractor end). Don't know about the NASA or EU contribution to failure, except that the project was on hold for a long time, and lost the original contributors (at our end anyway, so failure of continuity). I will never forgive NASA for the Apollo 1 fire, or the two lost Shuttles ... all preventable. Better to use robots rather than callously lose astronauts to political calculation.
Usually most people are capable of handing things they have already handled .. until the system decides to take a left turn at Albuquerque. If they are extrapolating, instead of interpolating, the failure rate is much higher. They simply don't respect the unknown knowns, let alone the unknown unknowns. We engineers can be pretty complacent (see famous suspension bridge failure). But it takes a medical doctor to be really arrogant ;-)
Asking my Mars buddy if he knows what happened with the new probe. Remember, per Non Disclosure Agreement ... it is possible that except for scuttlebutt, we may never know.
