Space Micro Delivers Single Board Computer for Lunar IceCube Mission

San Diego, CA – February 8, 2018

Space Micro delivered a Proton400k™ single board computer to Morehead State University for use in the Lunar IceCube mission.

Lunar IceCube is a NASA mission supported by NASA’s Advanced Exploration Systems (AES) and led by Morehead State University to enable future human exploration of the lunar surface. A 6U CubeSat slated for launch on the Exploration Mission 1 (EM-1), Lunar IceCube will investigate the transport physics of water ice and other volatiles while in lunar orbit. Space Micro’s Proton400k™ will be used both as the flight computer and the payload processor on the satellite.

The Proton400k is a radiation-hardened, high performance, space qualified single board computer powered by an advanced P2020 PowerPC® processor capable of running at up to 800MHz and is available in a variety of configurations. The unit supplied to Morehead State fits in Space Micro’s ProtonX-Box form factor and features:

  • • 512 MB of DDR3 SDRAMwith EDAC, operating at 667 MT/sec
  • • Four asynchronous UARTs operating at 115.2 kbps
  • • 16 discrete digital I/O
  • • PPS signal
  • • I2C and SPI interfaces
  • • Space Micro patented Hardened CoreTM SEFI Mitigation

“We are pleased and excited to support this important university initiative with our space radiation-hardened processing capability,” said CEO David J. Strobel.

Lunar IceCube’s partners include NASA Goddard Space Flight Center, Jet Propulsion Laboratory, and the Busek Space Propulsion Company. EM-1 is the first planned flight of NASA’s new Space Launch System and is projected to launch in 2019, unloading Lunar IceCube and twelve other CubeSats into lunar orbit on a flyby.
