Spartan 211 (Shuttle Pointed Autonomous Research Tool for Astronomy 211) was a planned free-flying payload for EUV astronomy to be released and retrieved by the Space Shuttle mission STS-81L.
The satellite was to conduct research on spatially resolved spectroscopy of extended faint sources in the EUV. The payload was based on the Faint Object Telescope payload, which was launched successfully on Black Brant-5 sounding rockets on both 26 February 1986 (21.093 UG) and 13 March 1986 (21.095 UG) to observe comet Halley in the far ultraviolet.
Spartan-211 was cancelled.
