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

A day-and-a-half after lifting off from Cape Canaveral, a SpaceX Dragon supply ship arrived at the International Space Station on Wednesday with more than 5,800 pounds of experiments, provisions and other hardware to support the orbiting lab’s six-person crew. The cargo capsule was captured by the station’s robotic arm at 6:40 a.m. EDT (1040 GMT).

A European re-entry demonstrator launched aboard a solid-fueled Vega rocket at 1340 GMT (8:40 a.m. EST) from French Guiana, kicking off a whirlwind 102-minute around-the-world test flight to validate technologies that could be used on future reusable launchers and spaceships.

The Perseverance rover’s sterilized sample tubes — designed to seal Martian rock and sediment for eventual return to Earth — are installed on the spacecraft as teams at NASA’s Kennedy Space Center prepare to enclose the rover inside the payload shroud of its Atlas 5 launcher for liftoff July 20.
