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.
Preserving Hydrazine, Preserving Exploration
- Calca Solutions' manufactured hydrazine fuels the ground-breaking Martian exploration undertaken by NASA's Perseverance rover.
- DLA Energy provided the Orion capsule with 438 pounds of hydrazine, 6,245 pounds of Monomethyl Hydrazine, and 10,670 pounds of…
