STS-36 trajectory
« on: 11/20/2010 05:55 pm »
STS-36 is the only flight to have flown up to 62 deg inclination.  Reading the description, it says they did a dog-leg trajectory to reach that orbit.

They say they flew as if they were headed to their "max" 57-deg inclination, then dog-legged to reach 62, having gotten a waiver to overfly some polulated areas.
Watching the video, I can't see any difference between it and other flights.. was the dog-leg maneuver done w/the SRB's still attached, or after SRB-sep?  If after, when during the ascent was it done?

After SRB sep. First-stage guidance is open-loop.
