Meteoroid Technology Satellite (also called as MTS or Explorer 46) was a NASA satellite launched as part of Explorers program. MTS was launched on August 13, 1972 on Wallops Flight Facility, with a Scout-D rocket. The objectives of the MTS were to measure the meteoroid penetration rates in the bumper-protected target, and to obtain data on meteoroid velocity and flux distribution. The central hub of the satellite was 3.20 metres (10.5 ft) long and carried the velocity and impact experiments. Bumper targets extended from the satellite, giving it an overall width of 7.015 metres (23.02 ft).
