ICESat-2 explained

SciNews

Опубликовано: 12 сент. 2018 г.

NASA's ICESat-2, the Ice, Cloud and land Elevation Satellite-2, will provide critical observations of how ice sheets, glaciers and sea ice are changing. ATLAS (Advanced Topographic Laser Altimeter System), the single instrument on ICESat-2, will measure melting ice sheets and investigate how this effects sea level rise, investigate changes in the mass of ice sheets and glaciers, estimate and study sea ice thickness, and measure the height of vegetation in forests and other ecosystems worldwide.

ICESat-2 orbit

SciNews

Опубликовано: 12 сент. 2018 г.

NASA's ICESat-2 spacecraft is designed to accurately measure land and ice elevations on Earth. ICESat-2 will be in a polar orbit which will provide high coverage near the poles where ice elevations are changing relatively quickly.

NASA's Ice, Cloud and land Elevation Satellite-2, or ICESat-2, is scheduled to launch Saturday, Sept. 15, at 5:46 a.m. PDT (8:46 a.m. EDT). There is a 40-minute launch opportunity within the spacecraft launch window, which extends for 2 hours, 34 minutes. The 40-minute window is determined by super-cold liquid oxygen temperature (cryogenic propellant) effects on the Delta II rocket. The team is targeting the earliest opportunity within the spacecraft window, which could shift based on launch operations.
