We had a session with ISEE-3 today via Arecibo with support from AMSAT-DL/Bochum team in Germany. We engaged in “hammer mode” wherein we tried to open and close all of the latch valves repeatedly with the hope that this might get the propulsion system working. It did not. We then began to transition the spacecraft to science mode by turning on two additional science instruments. We’ll post a detailed update tomorrow.
