Landsat 6, equipped with upgraded versions of the instruments on Landsat 5, was designed to carry forward the Landsat program. It was launched on October 5, 1993 with a Titan II launch vehicle, but failed to reach orbit. Landsat 6 omitted the Multi-Spectral Scanner found on its predecessors, but carried an Enhanced Thematic Mapper, which improved on the previous Thematic Mapper by adding a 15m-resolution panchromatic band.
