Opportunity Fix
Date: 15 Apr 2003
Technicians remove one of the circuit boards on Mars Exploration Rover Opportunity. To gain access to the spacecraft, its lander petals were reopened and its solar panels deployed.
A concern arose during prelaunch testing regarding how the spacecraft interprets signals sent from its main computer to peripherals in the cruise stage, lander and small deep space transponder.
