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.[2]
The Landsat 6 satellite was built by Martin Marietta Astro Space.[3]
Design
Operations
The satellite was constructed from aluminum and used graphite struts. Landsat 6 had a hydrazine propulsion system. The spacecraft was powered by one solar array that had single-axis articulation and produced 1430 W. The power was stored in two NiCd batteries that had a capacity of 100 Ah. Data collected from the sensors was stored on tapes and transmitted to ground stations at 85 Mbit/s. The satellite was stabilized to 0.1 degrees in all three axes by using reaction wheels.[3]
Sensors
The Enhanced Thematic Mapper was designed and manufactured by Santa Barbara Research Center.[4]
