ISEE-3 Propulsion System Overview
The ISEE-3 spacecraft is a 16-sided drum-shaped structure designed for spin-stabilized operation. [click on image to enlarge] It measures 161 centimeters in height and 174 centimeters in diameter and had a nominal…
ISEE-3 Status Report 13 June 2014 – Green Light For Spin-up
NASA has given us approval to fire the spin thrusters on ISEE-3 to increase its spin from 19.16 rpm up to the mission specification of 19.75 +/- 0.2 rpm. This spin rate…
ISEE-3 Reboot Project Scheduled for DSN Doppler and Ranging Activity
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…
ISEE-3 Science Instrument Update 12 June 2014
As we recently reported, we are getting telemetry from ISEE-3 indicating that its entire suite of science instruments is powered up and has been powered up since NASA last commanded the spacecraft…
