**Summary**: Landsat 7’s nominal science mission ended in April 2022 after nearly 23 years of acquiring Earth imagery from 705 kilometers above the Earth. Landsat 7 is now in an extended science mission after having its orbit lowered by about 8 kilometers to make way for Landsat 9. In this episode, we discuss why Landsat 7 continues to collect imagery, the quality of the extended science mission imagery, and the advantages of having three Landsats operating at the same time.

**Guest**: Chris Crawford, USGS Research Physical Scientist, Landsat Project Scientist, Co-chair of the Landsat Science Team, Landsat Science Data Acquisition Manager

**Host**: Tom Adamson (contractor for USGS EROS)
