Lewis was one of two missions selected under NASA's SSTI (Small Spacecraft Technology Initiative) program to demonstrate advanced spacecraft technologies (11 July 1994). Lewis' payload consisted of:
After reaching orbit, the satellite spun out of control and was losing power just days after launch because an attitude-control thruster remained in the on position longer than planned, so that Lewis could not manouver to its operational orbit and decayed soon after.
