NISAR Opens Radar Data to Public on July 20 for Earth Research

Summary
July 20 marked the start of public access to NISAR radar data, opening the NASA-ISRO satellite’s observations to researchers worldwide.
Radar imagery can see through snow and deep into ice, letting scientists track glacier motion and detect properties of Antarctic ice that optical images cannot capture.
A newly released Antarctica image illustrates that capability: the apparent purple “hummingbird” is actually Nunatak Zaterjavshijsja, with ice flow and crevasses mapped in sharp detail.
Mission teams will keep rolling out more data as NISAR expands its role in studying and helping protect a changing planet.
