The Colorado River Basin Actionable and Strategic Integrated Science and Technology Team has created an interactive map of USGS projects to highlight the integrated science currently conducted within the Colorado River Basin. These projects are not all inclusive of the work conducted by the USGS within the CRB, but highlight the broad range of integrated science currently conducted.

Landsat 4 was launched on July 16, 1982, with joint control of the program by NOAA, NASA, and the U.S. Geological Survey. Each federal agency took on a different role.

Although only two Landsats were originally anticipated, the program’s principal scientists sought to launch a third satellite for continued coverage because they found a wide variety of applications for the data. There was also interest in advancing the sensors and improving the data.

A long string of Earth-observing orbiters began with NASA's Earth Resources Technology Satellite (ERTS). Launched in July 1972, it was the first satellite explicitly designed to study our planet. Three years later, the satellite was renamed Landsat 1. Outlasting its one-year design, Landsat 1 retired in January 1978.
