An application of ICESat data for detecting forest changes was presented.
这颗卫星的探测数据的应用，提出了森林变化。
The study looked at measurements taken of the Arctic region by the Icesat satellite, launched in 2003.
2003年发射的冰云和地面高度卫星对北极圈区域进行的测量给这项研究提供了参照。
One such satellite, NASA's ICESat, carries a laser altimeter to measure the height of the ice surface.
其中的一颗卫星，美国宇航局的icesat就携带着一个激光高度探测仪来探测冰面的高度。
The satellite Markus USES - ICESat - was retired in early 2010 after 7 years collecting data in Earth orbit.
马库斯所用的ICESat号卫星在沿地球轨道飞行，收集了7年的数据，已于2010年初退役。
Results from ICESat have shown that just since 2003, when ICESat was launched, the sea ice thickness has decreased by over two feet.
