The Landsat program has seen a literal world of changes in its 40 years of observing Earth. This interactive compares “before and after” views of some of those changes.
More frequent satellite observations, such as those of the Harmonized Landsat Sentinel-2 (HLS) dataset, are needed to fully capture flood dynamics in regions experiencing short-lived, ephemeral flooding.
OSAM-1 Lead Systems Engineer Wendy Morgenstern discusses NASA’s On-orbit Servicing, Assembly, and Manufacturing 1 mission to robotically refuel Landsat 7, a satellite that wasn’t designed to be serviced.
Data collected by citizen scientists like you helps land cover scientists evaluate the quality of the maps produced from satellites like Landsat.
I use Landsat data alongside other satellite and field data to map where and when crops like wheat are growing, to analyze different management practices including when crops are planted and harvested, to assess crop health and to forecast end of season yields.
