Video: Change of command aboard International Space Station

SpaceX transferred the first astronaut-ready Crew Dragon spacecraft Friday night from a fueling facility at Cape Canaveral Air Force Station to pad 39A at NASA’s Kennedy Space Center, where teams will join the capsule with its Falcon 9 launcher for liftoff later this month.

SpaceX called off the planned launch of a Falcon 9 rocket Saturday less than 15 seconds before liftoff to investigate the “slightly odd” behavior of the vehicle’s upper stage engine steering system, company chief Elon Musk said.

A Russian Soyuz booster blasted off from a snow-covered launch pad in Kazakhstan on Wednesday with nearly 6,000 pounds of fuel, water and supplies for the International Space Station.
