ISEE-3 Update: Countdown to Burn

The latest news from the ISEE-3 Reboot Project. Course correction burn is now to take place between 30 June and 2 July. From Space College:

We have received confirmation from NASA that we have been confirmed for time on the DSN (Deep Space Network) for two-way Doppler and ranging activities with the ISEE-3 spacecraft. This is being done so as to determine the location of ISEE-3 with great precision for navigation purposes. Based on this data we will conduct our course correction engine firing. We have moved that original firing date from 17 June to a window that currently covers 30 June and 2 Juy. As the DSN ranging data comes in that window will shrink. DSN ranging passes after the engine burn will help us calculate the result of that burn and the new trajectory that ISEE-3 is pursuing.

June 13, 2014, ISEE-3 Reboot Project Scheuled for DSN Doppler and Ranging Activity. Yesterday the project posted a report confirming that ISEE-3 science package is fully powered up and able to return data. They also stated that a growing number of former mission investigators and their successors have been gathering to aid in the task of interpreting what the spacecraft is sending back. Exciting times.
