Launched from Poker Flat Research Range
NASA press release
We had the Acquire command asserted thoughout the flight. We tried to acquire many times on the upleg, and finally suceeded when the Earth's limb left the field of view. We tracked fine during that time, at the top of the trajectory. On the downleg, we lost lock and again went into an acquire loop, generating another fine sequence of saved images. I stitched these upleg and downleg sequences into slideshows, nicely illustrating the dynamic nature of the geometry of the rocket, the Earth, and the target.
