To catch individual laser photons that have travelled more than 600 miles from a satellite to Earth and back, the satellite's telescope needs to be perfectly positioned. Last week, engineers and technicians at NASA's Goddard Space Flight Center in Greenbelt, Maryland, fitted the mirrored telescope of the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) into its place.
