ICESat-2 By the Numbers: 0.2

The video explains the precision of the Atlas laser, which can maintain its focus on a silver dollar from 28 miles away. This precision is crucial for measuring Earth's height from orbit. To maintain stability, the Atlas uses a beam steering mechanism, a motorized mirror that adjusts for thermal changes in orbit, preventing the laser beams from bending as they travel to Earth.
