Two days after lifting off from Florida’s Space Coast, a Dragon cargo capsule packed with more than 6,400 pounds of research experiments and crew supplies arrived at the International Space Station on Wednesday. Astronaut Jack Fischer used the station’s robotic arm to grapple the supply ship at 6:52 a.m. EDT (1052 GMT).

An atmospheric test model of Sierra Nevada’s Dream Chaser spacecraft, a cargo carrier for the International Space Station that will take off on top of an Atlas 5 rocket and land on a runway, is undergoing braking and steering checks in California ahead of a flight test later this year, the company said Monday.

Astronauts Jeff Williams and Kate Rubins ventured outside the lab complex Friday for a long-awaited spacewalk to attach a new docking mechanism, the first of two that will be used by U.S. crew ferry ships being built by Boeing and SpaceX to carry astronauts to and from the outpost, ending NASA’s sole reliance on Russian Soyuz spacecraft.
