ICESat-2's footprint
If ICESat-2 flew over a football field, it would take measurements within each yard line (green circles) – plus there's six of these green laser beams taking measurements at once!
The first ICESat instrument only fired 40 times a second, and would have taken a measurement in each end zone (red circles).
Bevy of biomes
Beyond icy areas, ICESat-2 will measure other ecosystems including forests, rain forests, deserts and urban areas. This poster is an outcome of the ICESat-2/SCAD Collaborative Student Project.
ICESat-2's 'Box Structure'
An engineer checks ICESat-2's box structure, shortly after its arrival in a NASA clean room in May. Over the next two years, engineers and technicians will attach electronics, optics, lasers, a telescope and more to the box, testing its function at each step.
Pho Movie Trailer
In Photon Jump, a 3-minute short animation, a brave photon of light named Pho must travel from a NASA spacecraft down to Earth and back again to help complete a crucial science mission. The animation was created by the ICESat-2/SCAD Collaborative Student Project involving students and faculty from the Savannah College of Art and Design.

ICESat-2 By the Numbers: Orbits
ICESat-2 is an incredibly precise space laser that features the latest in NASA technology To measure ice heights, engineers have to take ICESat-2’s instrument ATLAS to the extreme – sometimes going big, sometimes going small, but always keeping it precise.
