**Summary**: When the first Landsat satellite launched 50 years ago, it was the only game in town in terms of civilian land remote sensing. In the years that followed, a host of satellites have launched to serve similar purposes. But that data doesn't always play well together. Subtle differences between the measurements taken by satellites make it difficult to do apples to apples comparisons of land change. On this episode of Eyes on Earth, we hear from the USGS partners working with partners in Australia to launch a satellite cross calibration mission that will offer a common reference post and serve as a sort of “translation tool” to help remote sensing scientists to use datasets together to study changes to the Earth’s surface.

**Guests:**Greg Stensaas, USGS EROS, Grant Mah, USGS EROS, Jon Christopherson, USGS EROS contractor

**Host:** John Hult

**Producer:** John Hult

**Release date:** May 31, 2022
