Sea Ice Thickness
This animation shows how ICESat-2 measures sea ice thickness.
Laser Focus: Timing
Deputy Systems Engineer Phil Luers explains how the ATLAS transmitter and receiver subsystems come together to calculate the timing of photons, which, in turn, measure the elevation of ice.

ICESat-2's beryllium telescope during assembly
An engineer attaches components to ICESat-2's beryllium telescope, before it is attached to the satellite's ATLAS instrument.
ICESat-2 By the Numbers: Microradians
With extreme cold-weather gear, scientific instruments, and two tank-like snow machines called PistenBullys, ICESat-2 scientists traversed along section of the 88-degree south latitude line in an arc around the South Pole.

ATLAS box structure checkout
Engineers check on the box structure section of the ATLAS instrument, with the optical bench — with telescope attached — in the foreground. ATLAS is the sole instrument on the ICESat-2 satellite, and will measure the height of Earth.
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.

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, illustrated
ICESat-2 will use six laser beams to measure the height of ice, as illustrated in this not-to-scale artist's rendering. This illustration is an outcome of the ICESat-2/SCAD Collaborative Student Project.
NASA Space Laser Heads on a Road Trip
To deliver the instrument safely to the spacecraft for assembly and testing, the ATLAS team developed special procedures for packing, transporting and monitoring the sensitive hardware.

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.

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).
