Weather Delays SpaceX Cargo Launch to Space Station

SpaceX scrubbed the launch of a robotic Dragon cargo capsule to the International Space Station early Saturday, due to rainy and cloudy weather. The next attempt to launch SpaceX's Falcon 9 rocket from Cape Canaveral Air Force Station in Florida is set for 1:52 a.m. ET on Sunday, but NASA said the weather outlook is only 40 percent favorable.

This is SpaceX's fifth cargo mission to the space station, and the fourth under the terms of a 12-flight, $1.6 billion resupply contract with NASA. The spacecraft's 2.5 tons of supplies and equipment include a habitat with lab mice and the first 3-D printer to go into space. Earlier this week, California-based SpaceX won NASA's go-ahead to develop a crew-capable version of the Dragon capsule that could start ferrying astronauts in 2017.
