107 Cameras to Scan Discovery for Damage 261
neutron_p writes "We already know that NASA has prepared for space shuttle rescue mission if a crisis arises during Discovery's return to flight. NASA wants to avoid any risk, that's why they also installed 107 cameras which will film and photograph the orbiter's first two minutes of ascent from every angle scanning for pieces of insulation foam or ice fall off during the launch and strike the shuttle, the kind of damage that doomed its predecessor Columbia. Cameras will be installed around the launch pad and at distances of 6 to 60 kilometers (some 3.5 to 35 miles) away, as well as on board of two airplanes and on the shuttle itself."

I personally think it is. I regret the attitude after the accident were complete risk aversion was shown. I would have gotten into the next space shuttle (err, can not pay for it, so they have to offer), and I am sure I would have returned safely (chance less then 1% on a deadly accident).

Once you add a part, the harmonic frequencies are going to change, and you will have to recalculate the whole thing to check for problematic stress points and fatigue. (Ok, you think: Zero gravity, what stress, it floats by itself. In reality the spacestation is in a degrading orbit, so it has to be lifted once in a while, this uses thrusters which are carefully placed to boost the stations orbit. This also causes a lot of stress on the station!)
The harmonics are already a problem since not everything of the spacestation is in one plane, making it already very complex. The harmonics also dampen out pretty slow since there is not atmosferic friction (there are dampeners though).
