说明: 火星上的沙尘暴不会真的把太空船吹翻,不过它们能把太阳给遮住。在3个月前,一个广及全行星的沙尘暴,造成位在奋进坑西缘附近的机会号火星车严重缺乏日照。由于缺乏可用来充电的阳光,倚靠太阳能供电的机会号不得不进入休眠模式,也让控制人员在长达115火星日期间,未收到来自这部火星车的任何讯息。不过随着沙尘暴消散,尘埃也逐渐沈降。在9月20日,火星探勘号轨道船的HiRISE相机拍摄上面这头影像时,已有百分之二十五的阳光可射到火星表面。影像里的白框,标记了47公尺宽的区域,中心的亮斑确认是目前暂时无通讯活动的机会号火星车

Explanation: On Marsdust storms can't actually blow spacecraft over,but they can blot out the Sun.Over three monthsago a planet-wide dust storm causeda severe lack of sunlight for the Mars rover Opportunityat its location near the west rim of Endeavour crater.The lack of sunlight sent the solar-powered Opportunity intohibernation and forover 115 solscontrollers have notreceived any communication from the rover.The dust is clearingas the storm subsides though.On September 20th, when this image was taken by theMars Reconnaissance Orbiter's HiRISE camera, about 25 percent ofthe sunlight was reaching the surface again.The white box marks a 47-meter-wide (154-foot-wide) area centered on ablip identified as thesilent-for-nowOpportunity rover.
