Small Astronomy Satellite
Small Astronomy Satellite A NASA series of three small satellites devoted to X-ray and gamma-ray astronomy. SAS-1, also known as Explorer 42, was renamed
Uhuru after launch in 1970. It was the first X-ray satellite, and performed the first X-ray sky survey. SAS-2, otherwise known as Explorer 48, was a gamma-ray mission, launched in 1972November. The last of the series, SAS-3, or Explorer 53, was launched in 1975May to study individual X-ray sources.
