A data acquisition system is being developed for use on the NASA Lunar-Mars series of missions. The unit will accept inputs from multiple types of sensors, employing three types of input channels that each incorporate programmable elements to accommodate a wider variety of input signals. Based in part on a subsystem called the Remote Health Node (RHN) that was originally developed during the 1990s for use on the now-defunct NASA X-33 "space plane", the Remote Electronics Unit (REU) is being developed using a 0.5 micron Silicon Germanium (SiGe) BiCMOS technology from IBM with a circuit library that has been designed to operate normally across a temperature range from -180 degrees C up through +125 degrees C. This NASA project is one of the Exploration Technology Development Projects (EDTP) associated with NASA's Radiation Hardened Electronics for Space Environments (RHESE) program. A large team combining both University and Industry partners is being led by Dr. John Cressler from the Georgia Institute of Technology. Other University team members include the University of Arkansas, Auburn University, the University of Maryland, the University of Tennessee, and Vanderbilt University. Industry members are BAE Systems, Boeing, Lynguent, and Jet Propulsion Laboratories. IBM is acting as the foundry. The REU will support sixteen input channels, including twelve low speed channels designed for signals in the 1-200 Hz range, two higher speed channels that support inputs up to 5 KHz, and two charge amplifier channels that support piezoelectric transducers up to 5 KHz.
