The capabilities of the Advanced Land Imager instrument to be demonstrated on the flight will serve multiple purposes, according to Dr. Charles Kennel, NASA Associate Administrator for Mission to Planet Earth. The instrument will provide remote-sensing measurements of the Earth consistent with data collected since 1972 through the Landsat series of satellites, which is used by farmers, foresters, geologists, economists, city planners and others for resource monitoring and assessment. In addition, it will acquire data with finer spectral resolution, a capability long sought by many elements of the Earth observation data user community, and it will lay the technological groundwork for future land imaging instruments to be more compact and less costly. "We looked at nearly a dozen different mission concepts in some detail, and a land surface imaging mission clearly bubbled to the top of the priority list," Kennel said. "It will enable first-class science, while validating breakthrough technology with clear potential capabilities, both commercially and to the future of NASA's Earth Observing System." As designed, the Advanced Land Imager represents an approximate sevenfold decrease in mass and electrical power usage demands compared to the current Landsat 5 multispectral instrument. In addition, it extends the existing measurement capabilities through the incorporation of an advanced high resolution hyperspectral imaging "spectrometer-on-a-chip." This novel, wide- field observing system requires no scan mirror. It is built around a lightweight integrated silicon carbide structure and optical system, with an innovative in-flight calibration system. Under project management by NASA's Goddard Space Flight Center, Greenbelt, MD, the Advanced Land Imager will be developed from instrument technologies proposed by members of the existing New Millennium Integrated Product Development Teams. For this mission, the team of industry partners will be led by the Massachusetts Institute of Technology's Lincoln Laboratory, Lexington, MA, a federally funded research and development center. Lincoln Lab and its partners will provide open access to U. S. industry regarding the design and performance of the Advanced Land Imager, with the explicit purpose expediting the transfer of this technology into the commercial sector. The instrument will feature 10-meter ground resolution in the panchromatic (black-and-white) band and 30-meter ground resolution in its other spectral bands, using a four-chip multispectral focal plane array that covers seven of the eight bands of the current Landsat. Hyperspectral capabilities, which further split these bands into highly differentiated images, will be tested to show that they can be combined into traditional Landsat-equivalent data sets. "The combination of multispectral and hyperspectral capabilities in a future operational system would preserve and continue the invaluable Landsat-based record of global land cover change, while opening up new windows on the Earth in areas like precision vegetation studies and more accurate mineral identification," Kennel said. The spacecraft support structure, which includes an advanced power and data- handling bus, will be provided by Swales & Associates, Inc., Beltsville, MD. and Litton Industries, College Park, MD. The spacecraft will also incorporate advanced spacecraft technologies made available through the New Millennium Integrated Product Development Teams. The advanced power and data-handling bus will be provided through a Space Act cost-sharing agreement with Litton Industries. The agreement calls for Litton to develop technology transferred from NASA, commercialize it, and also integrate it into the New Millennium spacecraft's supporting bus structure. Additionally, the agreement provides Litton with a two-year license to commercialize new technologies acquired from the agency. "This innovative arrangement, which includes a major commitment from Litton to integrate and deliver the hardware, represents an exciting new way of doing business for NASA Goddard," said Center Director Joseph Rothenberg. Further potential industry partnerships in the mission beyond those already identified will be solicited in a workshop to be held during upcoming advanced definition studies. The total NASA cost of the first New Millennium Earth science mission, including its Small Expendable Launch Vehicle, has been capped at $90 million. Launch is planned for late 1998. The current mission operations concept for the New Millennium flight has the spacecraft flying autonomously several minutes ahead of the ground track flown by the planned Landsat 7 satellite, to provide accurate paired-scene comparisons between the new and the traditional observing technologies. Evolutionary versions of the Advanced Land Imager would be candidates for flight on future generations of NASA Earth Observing System missions, beginning with the AM-2 spacecraft. Formally started in NASA's FY 1996 budget, the goal of the New Millennium program is to identify, develop, and flight validate key instrument and spacecraft technologies that can enable new or more cost-effective approaches to conducting science. The overall program is managed by the Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Space Science, Office of Space Access and Technology, and Office Mission to Planet Earth, Washington, DC.
