EaglePicher Helps Power Mars Mission

Products from EaglePicher
Technologies, LLC played an integral role in powering NASA’s Mars mission.
The Mars Exploration Rovers, Spirit and Opportunity used EaglePicher
Technologies (EPT) thermal batteries to successfully assist in the critical
entry, descent and landing sequences on Mars.

Each Rover had two thermal batteries manufactured at EPT’s Joplin,
Missouri facility, located on the back shell to provide high-current bursts
for firing several pyros (firing mechanisms). These pyros enabled parachute
deployment, heat shield release, TIRS (Transfer Impulse Reaction System) and
RAD (Rocket Assisted Descent) rocket firing.

The batteries made the long trip to Mars in an inactive state. Upon
entering the Mars atmosphere, a high-current pulse activated the batteries by
generating a high temperature that melted electrolyte pellets and thus
provided ionic contact between electrodes within the battery.

Even though the operating life after activation is fairly short, the
thermal batteries are designed to provide extremely high power over a short
period of time, making them ideal for the Mars Rovers. EaglePicher made
similar batteries for NASA’s earlier missions, Mars Pathfinder and Mars

The thermal batteries for Mars Exploration Rovers were designed and
fabricated by EaglePicher Technologies, LLC under the cognizance of battery
and mission assurance engineers from NASA’s Jet Propulsion Laboratory.
