A series of photos released recently show that the northern part of Mars is in the dust storm season.

The European Space Agency's (ESA) Mars Express orbiter has captured many storms that have ravaged the Martian Arctic in the past few months.

European Space Agency officials wrote in a statement issued with the photo on July 4: "At present, the northern hemisphere of Mars is in the spring, and on the edge of the seasonally declining (polar) ice cap, water ice clouds and small ones are often observed. Dust activity."

The Mars Express "has observed at least eight different storms on the edge of the ice sheet from May 22 to June 10, and they quickly formed and dissipated within 1-3 days," the official added.

But such a storm is not always so short and limited. Last summer, a Martian dust storm broke out near the equator and quickly spread to full Mars, covering the entire Mars for a few weeks. The thick dust storm made NASA's solar Opportunity probe no way. Collecting the sun ended its long and successful career.

Between the end of May and the beginning of June 2019, several different sandstorms appeared on the Arctic ice cap of Mars. These photos were taken at a height of 6,200 miles (10,000 kilometers) by the European Mars Express spacecraft. This strip of image covers an area of 2000 × 5000 kilometers, extending from the Arctic to the equator to Mount Olympus and Mount Euresian. (Source: ESA/DLR/FU Berlin, CC by sa 3.0 IGO)

xx火星快车的一些最新版本显示,最近的区域风暴正从冰盖边缘向南移动,并向巨大的奥林匹斯山和极乐世界展开。

欧洲航天局的官员写道,当风暴到达这些火山时,由于灰尘涌入大气层,“先前形成的云层开始蒸发。”

火星快车于2003年12月进入火星轨道,比“机遇号”及其双胞胎兄弟“勇气号”降落前几周。
