On November 18, 2013, the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft was launched into space to begin its ten-month journey to Mars. The spacecraft is being powered by a combination of solar arrays and two advanced, space-qualified, 28-Volt, 55-Ah Yardney lithium-ion batteries.
The MAVEN spacecraft was launched on an Atlas V-401 rocket, which also includes 12 Yardney Silver Zinc batteries (booster main 2, FTS 4, and Pyro 6). The lithium-ion batteries have additionally powered the Mars Rover, Phoenix Mars Lander, and other satellites.
The MAVEN’s solar arrays produce 1,150 Watts of energy to power the spacecraft and its payload. The spacecraft has several scientific instruments to study solar winds, magnetic field, and other characteristics of the Martian upper atmosphere. The lithium-ion battery stores extra energy at times when demand is low, provides extra power when demand is high, and is used for load leveling and transient suppression in the power system.
