- ISEE-3 Engines Fired For Spin-Up – Space College
- Additional ISEE-3 Spin-up Confirmation – Space College
- ISEE-3 Current Location 3 July 2014 – Space College
Today we fired the A and B thrusters on ISEE-3 to perform a spin-up burn. Preliminary results confirm the burn and a change in rotation. Spin rate was originally 19.16 rpm. It is now at 19.76 rpm. The original mission specifications call for 19.75 +/- 0.2 rpm- so we are exactly where we wanted to be.
We are now collecting telemetry in advance of our next DSN pass and our ATP-3 review with NASA. The earliest we expect to make our Trajectory Correction Maneuver is next week.
All in all, a very good day.
