NASA CubeSat to test miniaturised weather satellite
08 November 2017
Behind every weather forecast - from your local, five-day prediction to a late-breaking hurricane track update - are the satellites that make them possible. Government agencies depend on observations from weather satellites to inform forecast models that help us prepare for approaching storms and identify areas that need evacuating or emergency first responders.
Weather satellites have traditionally been large, both in the effort needed to build them and in actual size. They can take several years to build and can be as big as a small school bus. But all of that could change in the future with the help of a shoebox-sized satellite that will start orbiting Earth later this month.

There are also two small, thin tape-measure antennas on the top, used for UHF radio communication with the ground station.
