NASA and JPL ground controllers coax the radiation-damaged tape recorder built into the Galileo probe into working again, finally allowing several weeks worth of scientific data to be replayed to Earth. The damage was suffered during Galileo’s closest pass by Jupiter to study the tiny moon Amalthea the previous month. With layoffs looming for many of Galileo’s ground control staff in early 2003, this is Galileo’s last chance to relay its scientific findings back to Earth. It is on a trajectory that will end its mission by plunging into Jupiter in 2003.
