Let's say goodbye to Landsat 7 and say hello to Landsat 9 ! Landsat-9 will replace Landsat 7 in its orbit. The new OLI-2 and TIRS-2 sensors of the Landsat 9 will be a slight improvement from its predecessor. According to the overview, the spatial and spectral resolution remains the same - moderate spatial resolution—15 m, 30 m, and 100 m depending on spectral band—and the ability to detect the same range in intensity as Landsat 8, or better The OLI–2 will capture observa­tions of the Earth’s surface in visible, near-infrared, and shortwave-infrared bands with an improved radiometric precision (14-bit quantization increased from 12 bits for Landsat 8), slightly improving overall signal to noise ratio TIRS-2 will measure thermal radiance emitted from the land surface in two thermal infrared bands using the same technology that was used for TIRS on Landsat 8, however TIRS-2 will be an improved version of Landsat 8’s TIRS, both with regards to instrument risk class and design to minimize stray light Both OLI–2 and TIRS–2 have a 5-year mission design life, although the spacecraft has 10+ years of consumables Here are the spectral bands from OLI-2, Band 1 Visible (0.43 - 0.45 µm) 30-m Band 2 Visible (0.450 - 0.51 µm) 30-m Band 3 Visible (0.53 - 0.59 µm) 30-m Band 4 Red (0.64 - 0.67 µm) 30-m Band 5 Near-Infrared (0.85 - 0.88 µm) 30-m Band 6 SWIR 1(1.57 - 1.65 µm) 30-m Band 7 SWIR 2 (2.11 - 2.29 µm) 30-m Band 8 Panchromatic (PAN) (0.50 - 0.68 µm) 15-m Band 9 Cirrus (1.36 - 1.38 µm) 30-m Two spectral bands from TIRS-2, Band 10 TIRS 1 (10.6 - 11.19 µm) 100-m Band 11 TIRS 2 (11.5 - 12.51 µm) 100-m The good thing is Landsat 9 will image the Earth every 16 days in an 8-day offset with Landsat 8, which means increased temporal coverage of observations.
