The upcoming mission will be the third of 12 Dragon delivery missions to the space station by California-based SpaceX under a .6 billion contract with NASA. SpaceX launched its first cargo run to the station in 2012. Another company, Orbital Sciences Corp. of Dulles, Va., has a $1.9 billion contract for eight cargo missions — the first of which launched in January — using its own Antares rockets and Cygnus spacecraft.
The weather forecast on Friday predicts only a 40 percent chance of good launch conditions, but SpaceX officials plan to complete helium leak repairs in time to make a second launch attempt this week.
