An attendee of the USA Science and Engineering Festival is measured by a laser at the NASA Stage. A NASA Staff member describes the Ice, Cloud, and land Elevation Satellite (ICESat) mission, which operated from 2003-2009, and pioneered the use of laser altimeters in space to study the elevation of the Earth's surface and its changes. ICESat-2 is a follow-on mission to continue the ICESat observations and is scheduled to launch in 2017. The USA Science and Engineering Festival took place at the Washington Convention Center in Washington, DC on April 26 and 27, 2014. Photo Credit: (NASA/Aubrey Gemignani)
