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.
A year ago today a derecho, a series of thunderstorms with hurricane-like winds and heavy rains, struck Iowa with very little warning. The National Oceanic and Atmospheric Administration (NOAA) put together a multi-media story map to tell the tale of this eventful day. Hundreds of thousands of trees were lost or damaged. Homes and buildings were destroyed. Many people lost power for days or even weeks.
Have you visited the NASA’s Earth Observatory? It is a NASA website that helps make satellite imagery relevant to the general public and it is a great place to find images for presentations or use in the classroom. In August 2020, the Earth Observatory featured a comparison of satellite images from July 2020 and August 2020 to show the extent of the derecho damage on Iowa cropland.
Each week NASA’s Landsat Science team will explore a unique aspect of Landsat earth science (see themes below). Weekly features include Landsat related crafts and games, revisiting each sequential Landsat mission as well a weekly postcard from camp. Stop by each week of camp to explore a new theme.

This week is the virtual American Society for Photogrammetry and Remote Sensing (ASPRS) conference. At today’s conference, the ASPRS Lifetime Achievement Award was presented to Virginia T. Norwood.
Virginia Norwood is known as the “Mother of Landsat.” When interviewed by Laura Rocchio for a NASA Landsat Science article, Ms. Norwood was asked if she is comfortable with this title and she replied, “Yes. I like it, and it’s apt. I created it. I birthed it; and I fought for it.” In recognition of her contributions to satellite communications and optics for over 40 years, including the design, building, promotion and operation of the first multspectral scanner (MSS) on-board Landsat-1, Ms. Norwood was awarded the 2021 ASPRS Lifetime Achievement Award.
Today we are celebrating remote sensing, the study of the earth using secondary observations from instruments such as planes, kites, drones, satellites as an exciting and powerful educational tool to help us show changes over time.
This year the AmericaView/NASA team has put together a fun and beautiful educational poster!
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.
Google Earth Engine is a platform for exploring and analyzing satellite imagery. It is available for academic, non-profit, business and government users.
Several members of the AmericaView community have created tutorials to provide a foundation to quickly begin learning and using Google Earth Engine (GEE). If you are new to GEE, you will want to start with this Google Earth Outreach tutorial. You may need to sign-up for a GEE account with an existing Gmail email address.
Gregg Hadish gave a great presentation about the Iowa Geographic Map Server to celebrate Earth Observation Day. It was a hands-on demonstration of the Iowa Geographic Map Server ArcGIS App which meant participants could follow along as he explained the various features and functions of the map server. Gregg also showed participants how to leverage map server layers within their own ArcGIS Online organizational accounts and basics for creating their own apps.
Thank you, Gregg for a great demo!
