47-year-old Voyager 1 spacecraft just fired up thrusters it hasn't used in decades
Currently the farthest spacecraft from Earth, Voyager 1 is about 15 billion miles (24 billion kilometers) away. The probe operates beyond the heliosphere — the sun’s bubble of magnetic fields and particles that extends well beyond Pluto’s orbit — where its instruments directly sample interstellar space.
Earlier this year, engineers spotted an issue when the fuel tube inside one of Voyager’s thrusters became clogged. If the thrusters are clogged, they can’t generate as much force to keep the spacecraft steady. Voyager’s thrusters keep the spacecraft oriented in a way that it can communicate with Earth.
I wonder how long the spacecrafts we launch these days would fare.
