NASA research pilot Tom Ryan snapped this self-portrait while flying NASA’s ER-2 Earth Resources aircraft on a high-altitude mission over New Mexico to check out the Multiple Altimeter Beam Experimental Lidar (MABEL) laser altimeter in April 2011. MABEL was developed to demonstrate the photon-counting altimetry approach chosen to help scientists simulate measurements from NASA’s ice-observing satellite, ICESat-2, scheduled for launch in 2016.April 5, 2011
