The Solar Mesosphere Explorer ( SME ) or Explorer 64 was a research satellite of NASA , the ozone-generating and -zerstörenden processes in the mesosphere and upper stratosphere has researched the earth and the influence of solar radiation on these processes. The satellite was launched from Vandenberg on October 6, 1981 with a Delta 2310 rocket. After launch, SME entered a sun-synchronous low earth orbit. It was spin stabilized at 5 revolutions per minute.

SME was 1.7 m high, 1.25 m in diameter and consisted of two main modules, the satellite bus and the instrument panel. For the scientific measurements, SME had five instruments.

SME transmitted data to Earth over a period of 7.5 years up to April 4, 1989 and burned up in the Earth's atmosphere on March 5, 1991.
