[ Music ] NASA's latest Earth-observing instrument is complete and ready for space. Built by Ball Aerospace, the Operational Land Imager 2 (OLI-2) will detect visible and infrared light reflected from the Earth's surface. Observing the same location every 16 days, OLI-2 will continue five decades of observations detecting deforestation monitoring crop conditions tracking potentially toxic algal blooms and watching the human imprint on our planet. Now complete, OLI-2 is ready for its next step: assembly on to the Landsat 9 spacecraft.
