A broken thruster jeopardized Voyager 1, but engineers executed a remote fix
Earlier this year, NASA faced a critical decision that could have ended Voyager 1’s mission. Launched in 1977, Voyager 1 relies on roll thrusters to keep its antenna aimed at Earth. After years of using backup thrusters due to primary failure, engineers feared both systems might fail as residue built up in the fuel lines. With the only ground antenna capable of contacting Voyager 1 … Continue reading A broken thruster jeopardized Voyager 1, but engineers executed a remote fix
