American earth land resources satellite. One launch, 1993.10.05. Landsat 6 was designed to continue the Landsat program and carried an improved suite of instruments.
However, it failed to achieve orbit during launch, and forced the continued operation of the failing Landsat 4 and 5 vehicles.
The spacecraft had a structure of aluminum with graphite struts and a hydrazine propulsion system. A single solar array with 1-axis articulation produced 1430 W (BOL) and recharged two NiCd batteries with 100 AHr total capacity. Data was stored on-board using tape recorders for direct downlink to ground stations at 85 Mbps. The spacecraft was 3-axis stabilized, zero momentum with control to 0.01 deg using reaction wheels. The payload included the Enhanced Thematic Mapper (ETM) designed to provide 15 meter resolution in the panchromatic band and 30 meters resolution in the multispectral bands.
