Any weblinks where we can learn something about the where-abouts of ICE/ISEE ( International Comet Explorer / International Sun Earth Explorer ) as the craft was expected to return to Earth in 2014?

ISEE-3 Engines Fired For Spin-Up
QUOTE 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. The rotation rate is now almost exactly right where they wanted it. A big step in preparing for the upcoming "Big Burn". I admit that I was starting to get worried about how long it was taking to get this done, the available time before it would be too late is limited. |
