The objective of the MIDAS experiment was to measure the precise electrical properties of several high temperature superconductor (HTS) materials during spaceflight. MIDAS is a space experiment which launched in September of 1996 on the Shuttle (STS-79), and was transferred to the Mir Space Station for several months of operation. MIDAS was returned to Earth in January of 1997 by STS-81. MIDAS was developed at NASA Langley Research Center.
