Video: Soyuz MS-01 leaves the space station for landing

Russian launch crews on two continents are putting the final touches on a pair of Soyuz rockets scheduled to blast off less than two hours apart Friday — one carrying a three-man crew to the space station, and another boosting two European navigation satellites into orbit from the Amazon jungle.

The launch an Ariane 5 rocket with Brazilian and Korean communications satellites that was set for this week has been postponed indefinitely after protesters blocked access to the French Guiana spaceport.

An automated Progress cargo freighter docked with the International Space Station Monday to deliver 2.7 tons of supplies, fuel, water and oxygen to the orbiting research complex.
