在火星上拍摄了雪崩

Hi-RISE, the High-Resolution Imaging Science Experiment camera aboard NASA’s Mars Reconnaissance Orbiter (MRO) captured this avalanche plunging down a 1,640-foot-tall (500-meter-tall) cliff on May 29, 2019. The image also reveals layers at Mars’ north pole during spring. As temperatures increase and vaporize ice, the destabilized ice blocks break loose and kick up dust.

2019年5月29日，美国宇航局火星勘测轨道飞行器(MRO)上的高分辨率成像科学实验摄像机拍摄了从一个1640英尺(500米)高的悬崖俯冲下来的雪崩。这张照片还显示了火星北极春季的地层。随着温度的升高和冰的蒸发，不稳定的冰块会破裂，扬起灰尘。
