Space Geodesy Profiles: Jan McGarry

Scientists from NASA's Space Geodesy Project discuss the techniques they use to precisely measure the Earth's position in the universe, determine the Earth's center of mass, calibrate satellites, observe sea level rise, and track the movements of the tectonic plates. Mathematician Jan McGarry discusses the science and history of Satellite Laser Ranging (SLR), her role in developing the Next Generation Satellite Laser Ranging system, and her career at NASA's Goddard Space Flight Center.
