Q&A with Alvaro Gimenez, ESA’s director of science

A Falcon 9 rocket fired into a late-night sky Friday night over Cape Canaveral with a Dragon supply ship bound for the International Space Station. Eight minutes later, the booster returned to Florida’s Space Coast for SpaceX’s 50th landing of a Falcon first stage.

NASA announced Thursday it will fund development of a scientific instrument that will fly on Japan’s Martian Moons Exploration mission, a robotic probe set for launch in 2024 to bring back the first samples from Mars’ largest moon Phobos.

A Chinese rover outfitted with cameras, a weather station, and a sophisticated laser spectrometer could touch down on Mars as soon as Friday, a feat that would make China the second nation to successfully land and operate a spacecraft on the surface of the Red Planet.
