New Millennium Program's Earth Orbiter #1 Flight

NASA's Mission To Planet Earth is responsible for maintaining future Landsat data continuity while the New Millennium Program is responsible for flight validating breakthrough technologies to both reduce the cost of future science missions and to enhance their scientific capabilities. These two responsibilities are combined and met in the New Millennium Program's Earth Orbiter #1 Flight (EO-1). EO-1 will flight validate a number of advanced technologies that will reduce the cost of Landsat follow-on instruments while maintaining data continuity with earlier Landsat missions. These technologies are combined in an Advanced Land Imager (ALI) which includes a multispectral capability with Landsat-like bands, a miniature hyperspectral grating spectrometer to validate a new miniature hyperspectral wedge spectrometer, and a third hyperspectral imaging system to provide continual atmospheric correction. Mass-saving technologies have been systematically incorporated into the ALI with the result that it represents a seven-fold reduction in the mass, power, and volume of its predecessor.
