NASA mission detects mysterious dust cloud on Mars
Highlights
NASA\'s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has observed mysterious high-altitude dust cloud and aurora that reaches deep into the Martian atmosphere. The presence of the dust at orbital altitudes from 150 km to 300 km above the surface was not predicted earlier. Although the source and composition of the dust are unknown, there is no hazard to MAVEN and other spacecraft orbiting Mars.
Washington: NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has observed mysterious high-altitude dust cloud and aurora that reaches deep into the Martian atmosphere. The presence of the dust at orbital altitudes from 150 km to 300 km above the surface was not predicted earlier. Although the source and composition of the dust are unknown, there is no hazard to MAVEN and other spacecraft orbiting Mars. It is unknown if the cloud is a temporary phenomenon or something long lasting. The cloud density is greatest at lower altitudes. However, even in the densest areas, it is still very thin.
