What sensors will Landsat 9 carry?


Landsat 9 will carry the same, and improved, instruments that were onboard Landsat 8 — the Operational Land Imager-2 (OLI-2) for reflective band data, and the Thermal Infrared Sensor-2 (TIRS-2) for the thermal infrared bands. OLI-2 will have a slightly improved signal to noise ratio over Landsat 8's OLI. TIRS-2 is a Class-B instrument with a 5-year design life, whereas Landsat 8's TIRS is a Class-C instrument with a 3-year design life. Additionally, TIRS-2 will incorporate a key improvement of stray light correction, an issue that was discovered on Landsat 8 TIRS post launch. 

As with Landsat 8, Landsat 9 will have higher imaging capacity than previous Landsat missions, allowing for more valuable Earth observations to be added into the USGS Landsat archive.

Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.

Landsat Updates

The Landsat Update is an informal communication tool, prepared periodically and distributed electronically to USGS Landsat partners, to provide information about Landsat activities and related topics of interest.
