Preserving Hydrazine, Preserving Exploration

Hydrazine is a critical rocket fuel that enables spacecraft to maneuver and orient themselves. NASA’s Voyager 1 and 2 spacecraft, launched over 40 years ago, use hydrazine thrusters to keep their antennas pointed at Earth for communications. Buildup inside the thrusters now threatens to cut the mission short, so engineers are taking steps to reduce thruster firings and prevent clogs. Their efforts highlight the ongoing importance of hydrazine to space exploration.
