Ahead of the Landsat 9 satellite launch on Thursday, September 16, 2021 from Vandenberg Space Force Base in California, NASA is launching an interactive website to help the media and public learn more about the project and its history. Members of the media can attend a remote briefing Tuesday, August 31, 2021, tentatively set for 10 am EDT.
The Landsat 9 satellite continues the program’s role in monitoring, understanding, and managing land resources like agricultural crops, water, and forests that are necessary to sustain human life. Landsat 9 will replace Landsat 7 and join its sister satellite, Landsat 8. Together, they will collect images of Earth’s land surfaces every eight days.
Similar to Landsat 8, the Landsat 9 satellite carries two sensors, the Operational Land Imager-2 (OLI-2), built by Ball Aerospace & Technologies Corporation, and the Thermal Infrared Sensor-2 (TIRS-2), built at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. These detect the reflected light and heat emitted from Earth’s surface across the visible, near infrared, shortwave infrared, and thermal infrared wavelengths.
Onboard instruments will capture more than 700 new images daily across 11 wavelengths at a 30-meter resolution. They will deliver data related to coastal waters, forests, healthy and unhealthy plants, and wildfire scars in the visible light to thermal infrared ranges.
