O.K., I gotta riddle for ya!
Take a look at the ARTS2 data graph below and tell me what you're seeing. I flew the altimeter, and even it took me a minute to figure it out. (Hint: this is from a two day launch two weekends ago--altimeter hasn't been flown since. Data downloaded tonight.)
Just to make it interesting, I have a modest prize for the winner (i.e., first one to respond with the right answer).
