Ha!
They were able to recover the failed backup gyroscope by executing a series of attitude maneuvers while switching between operational modes on the gyro.
They literally shook the spacecraft and turned the gyro off-and-on.
Sometimes you gotta bang on something to get it to work!
I would love to buy a beer for the mission operations team member who came up with that idea!
- dmix 8y agoI wish I could do that to my software sometimes. Just bang my computer to get it working.

- weinzierl 8y agoPacking a punch is not only useful to fix things, but often the best way to get you an answer. Or as my control theory professor used to say: If you want to know how an unknown system reacts, first thing you do is to hit it hard. What he meant was that applying the Heaviside function to the inputs of a system to determine the step response [1] is one of the first things we should do.

- TeMPOraL 8y agoI remember that thinking from control theory classes, but I thought you use a Dirac delta as a hard shove. https://en.wikipedia.org/wiki/Impulse_response https://en.wikipedia.org/wiki/Impulse_response (Actually, our control classes told us to do both to get a basic view of a system.)

- amelius 8y agoMakes me wonder how long the fix will last, though.
