The first Delta 2 lifted off on February 14, 1989, and since then it has been the launch vehicle for Global Positioning System orbiters, Earth observing and commercial satellites, and interplanetary missions including the twin Mars rovers Spirit and Opportunity. Aside from measuring the height of Earth's land ice sheets (predominately located in Greenland and the Antarctic), ICESat-2's orbital LIDAR array will also be able to make less accurate but still useful measurements of changes in sea ice (particularly in the Arctic Ocean) and vegetation (tree canopies), the latter of which can help estimate and track global biomass changes.
The mission is a successor to the original Ice, Cloud and Land Elevation Satellite that operated from 2003 to 2009.
Known as laser altimetry, ATLAS is a rather exceptional example of LIDAR's space-based utility and has been created to reliably measure ice-sheet elevation changes of as little as 4mm per year, despite the fact that it will orbit 500 km (310 mi) above Earth's surface at a velocity of 7.8 km/s (4.9 mi/s).
ICESat-2 suffered delays because of problems with ATLAS, notably a failure of one of its lasers.

Once a mainstay of both government and commercial customers, the vehicle went through a gradual phaseout after the U.S. Air Force shifted payloads like Global Positioning System satellites to EELV-class rockets, including ULA's Atlas 5 and Delta 4 and, more recently, SpaceX's Falcon 9. If it goes up without a hitch, it will be the 100th successful launch in a row.
"Three, two one, liftoff!" said a launch commentator on NASA television.
"I'm a little bit sad".
Delta 2 rockets have launched scores of and satellite telephone relay stations, seven Mars missions - including the Pathfinder, Spirit and Opportunity rovers - Earth observation satellites, commercial payloads and trail-blazing NASA science probes, including the planet-hunting Kepler space telescope.
If all proceeds to plan, the Delta II's second stage AJ10-118K engine will reignite for 6 seconds at 47 minutes into the mission before deploying ICESat-2 into orbit.
The men were arrested in The Hague as part of an operation involving British, Swiss and Dutch intelligence agencies. Bucher said he did not know about the Russians being identified, detained or expelled from the Netherlands.
He added that CBDT was "very clear" that this year the government would be able to collect taxes in excess of the budgeted target. It also chose to curb non-essential imports and increase exports. "We are optimistic about our growth rate and tax collection".
