ICESat–2

Launch

The Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) mission is the second generation laser altimeter designed for cryospheric science measurements. Unlike its single-beam predecessor, ICESat-2 will split a single laser beam into six beams to enable measurement of elevation as well as surface slope, and uses a high-repetition rate laser to collect data every 70cm along the flight path.
