Landsat 9 is scheduled to be launched on September 16, 2021. This will mark almost 50 years of earth observation by US satellites. In preparation for this historic launch, we will be sharing several interactive documents about the history of the Landsat mission as well as the information about the Landsat 9 mission.

Today we would like to share with you, A History of the Landsat Program, developed by Ellie McGinty at UtahView. It’s an interactive Google Earth Tour, which documents major moments in earth observation history through a combination of maps, text, and curated images starting with the founding of the United States Geological Survey in 1879 through the birth of NASA in 1958 to the conception of Landsat in 1970 and all the way to the present day launching of Landsat 9.

Oh how the years go by: 40 years – Mount St. Helens

This week marks 40 years since the Mount St. Helens eruption. The image above is from the USGS Earthshots trading card series. The images are displayed in color infrared which is useful for showing living vegetation in red. The mountains surrounding Mount St. Helens are primarily forest. Notice the extreme change in the landscape from the 1973 image to the post eruption image in 1983. The damage was extensive and ash covered much of the surrounding forest land.
