The Landsat 9 instrument that will help scientists detect deforestation, monitor crops and track potentially toxic algal blooms, among many other uses, is now built, tested, and in place to be assembled onto the spacecraft.

The Operational Land Imager 2, or OLI-2, will detect visible and infrared light from Earth's surface, providing data on our changing planet. Like its predecessor that launched in 2013 on the Landsat 8 satellite, OLI-2 contains thousands of sensors that view a swath of Earth's surface in nine spectral bands, optimized to detect different features on the surface.
