SpaceX’s Falcon 9 rocket will go from Cape Canaveral to low Earth orbit in less than 10 minutes Saturday with a Dragon capsule heading for the International Space Station carrying nearly 5,500 pounds of supplies and experiments.

Astronauts Shane Kimbrough and Thomas Pesquet put on their self-contained spacesuits and headed outside the International Space Station on Friday for a six-and-a-half hour excursion to prepare for the relocation of a docking adapter, service the lab’s Dextre robot, and install a new computer relay box.

The Dragon spaceship poised for launch Tuesday will carry more than 2.5 tons of equipment for the International Space Station’s six-person crew, making the first U.S. supply delivery to the orbiting research complex since the crash of an Antares cargo rocket in October.
