Lift-off of the Soyuz rocket from Baikonur Cosmodrome in Kazakhstan came at 5:20 a.m. EDT (3:20 p.m. local time) on June 14. Less than 10 minutes after launch, the rocket sent into space a Progress cargo craft.
The Progress will take two days to reach a docking platform at the orbiting space lab. The ISS was orbiting the Earth some 258 miles above the launch site at the time of lift-off.
Contents of the craft also include several small satellites to be released by ISS crew later this year in a spacewalking maneuver.
Boeing and SpaceX hold NASA contracts to begin astronaut shuttles to the space station eventually.
SpaceX staged its most recent unmanned ISS cargo delivery on June 3.
