ISEE-3 Reboot: Data, Trajectories, and Engine Burns

ISEE-3 Reboot Project Update: BULLSEYE! and More
“If we can maneuver the spacecraft by June 17th we get the very small delta V number for the maneuver above. However, this starts to climb rapidly as the spacecraft gets closer to the moon. Also we cannot at this time rule out a lunar impact. It is imperative that we get a ranging pass as soon as possible. We also need time to not only evaluate the health of the spacecraft, but to test the systems, the catalyst bed heaters for the propulsion system, the valve heaters, analyze the rest of the propulsion, power, and attitude control system as rapidly as possible. This will be a lot of commanding so we have to move into high gear next week.”
