A massive dust storm has descended on Mars, surrounding the Opportunity rover in a blanket of dark dust that's estimated to be bigger than the entire North America. With the rover running on solar power, the storm is a huge threat to its survival.
The Soyuz MS-09 spacecraft docked on the International Space Station, carrying three new crew members who will be living aboard until December. The trio's arrival brings the total ISS residents to six.
Life on Mars? Maybe. NASA's Curiosity rover just found ancient building blocks of life on Mars, paving the way for the search for life in Earth's closest neighbor.
