Q&A with Michel Denis, ExoMars flight director

Soaring into the night sky over a guarded Russian military base, a 1.2-ton European satellite rocketed into orbit Tuesday to regularly measure how the world’s oceans and ice sheets respond to climate change and drive global weather patterns.

NASA’s Perseverance rover will depart Cape Canaveral Thursday on a $2.7 billion mission to Mars, carrying with it the first interplanetary aircraft, sophisticated instruments to search for signs of ancient life, and drill to core samples for eventual return to Earth.

Imagery captured by a sharp-eyed camera aboard a NASA orbiter shows where Europe’s Schiaparelli lander cratered on Mars last week, exploding into fine bits of shrapnel and debris after after an apparent software problem doomed the mission, officials said Thursday.
