ISEE-3 Engines Successfully Fired For Spin-Up .
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.
