Sustainable Land Imaging (SLI-T)

Since 1972, the Landsat series of satellites have provided multispectral measurements of land and coastal regions, the longest continuous record of Earth’s land areas from space. While Landsat data provide consistent and reliable information for scientific research, policy, and commercial uses, there has not been a robust plan to assure Landsat-like measurements in future decades. A 2013 report from the National Research Council (Landsat and Beyond: Sustaining and Enhancing the Nation’s Land Imaging Program) detailed a number of recommendations for sustainable land imaging, and a 2015 Presidential budget request for FY16 echoed the recommendations, including the investment in land-imaging technologies. In response, NASA initiated the Sustainable Land Imaging – Technology (SLI-T) program to support innovative technology development activities leading to new Landsat-like instruments, sensors, components, and measurement concepts.

The SLI-T program issued its first competitive solicitation in December 2015 and awarded six projects, out of 33 proposals received, in August 2016. The solicitation sought proposals in two categories: 1) Advanced Technology Demonstrations (ATD) that provide improved, innovative, full-instrument concepts for potential infusion into the architecture and design of Landsat-10; and 2) Technology Investments (TI) to develop and mature component or breadboard-level technologies that have long-term potential to significantly improve future land imaging instruments.
