1. • • NASA's upcoming satellite mission NISAR, scheduled to launch next year in a joint project with India's space program, will use two different radar systems to track subtle changes in the Earth's surface to less than a half-inch. This will allow better detection of ice sheet collapse and the melting of glaciers.

   How do satellite Radars work?

   • Both radars work by bouncing microwave signals off of the planet’s surface and recording how long the signals take to return to the satellite as well as their strength when they return. The larger the antenna sending and receiving the signals, the higher the spatial resolution of the data.

   What is synthetic aperture radar (SAR) & how does it work?

   • Synthetic aperture radar (SAR) allows satellites to bounce radar signals off the ground and interpret the echo – and it can even peer through clouds. Clouds cover around two-thirds of the world at any one time, preventing conventional satellites from seeing much of the planet.
