Q&A with Michel Denis, ExoMars flight director

The effects of a global dust storm on Mars have been observed by NASA’s plutonium-powered Curiosity rover, which continues its scientific campaign as the thick veil of dust continues starving the aging Opportunity rover of solar energy on the other side of the planet.

Christina Koch, veteran of six spacewalks outside the International Space Station — including the first all-female excursion — will join a Russian commander and an Italian flight engineer for a fiery plunge back to Earth early Thursday, setting a new world record for the longest single flight by a female astronaut.

A Russian Soyuz spacecraft streaked into space and chased down the International Space Station Tuesday, but a problem with the ferry ship’s automated rendezvous system forced commander Yuri Malenchenko to take over manual control at the last minute.
