A private company's cargo ship will life off and head for the International Space Station Sunday night.
California based SpaceX will attempt to send a capsule to the lab and its three member crew.
Lift off is scheduled for 8:35 p.m. EDT. Right now, forecasters are giving it a 60% going as planned. Thick clouds and rain could interfere.
The last SpaceX capsule docked with the space station in May carrying supplies.
