Video: Change of command aboard International Space Station

SpaceX’s Falcon 9 rocket and Crew Dragon spacecraft were lowered horizontal on pad 39A at NASA’s Kennedy Space Center the day before launch, allowing teams to address an issue with a chilled water loop near the top of the strongback structure.

The threat from Hurricane Nicole churning toward a tracking station in Bermuda will keep Orbital ATK’s Antares rocket from launching on a space station cargo run until at least Sunday, officials said Tuesday.

With lingering uncertainty about when new U.S. commercial vehicles can regularly carry crews to the space station, NASA said Tuesday it will pay the Russian space agency more than $90 million for a round-trip ticket to the International Space Station on a Soyuz spacecraft later this year.
