Watch the astronauts give a tour of their new Crew Dragon spacecraft

Mostly clear skies and brisk westerly winds are forecast at launch time Friday afternoon for SpaceX’s first resupply mission to the International Space Station in nearly a year.

A three-man crew departed the International Space Station on Sunday, concluding more than five months aboard the orbiting research complex and heading for landing in Kazakhstan. Undocking of the Soyuz MS-07 spacecraft occurred at 0916 GMT (5:16 a.m. EDT), and the trio landed on the Kazakh steppe at 1239 GMT (8:39 a.m. EDT).

NASA’s decision to launch a satellite to search for planets around other stars on a SpaceX Falcon 9 rocket in 2017 will allow officials to cancel plans to order a solid-fueled kick motor to send the telescope into a unique high-altitude orbit, the mission’s top scientist said.
