SpaceX's capsule nears ISS for rendezvous A PRIVATELY-OWNED unmanned US space capsule is nearing the International Space Station (ISS), preparing to dock to deliver food, scientific materials and other crucial equipment. "Dragon is scheduled to be captured Sunday at 6:31am EST (2231 AEDT) by NASA Expedition 34 Commander Kevin Ford and NASA Flight Engineer Tom Marshburn," the US space agency NASA said in a statement. NASA said SpaceX's Dragon would be installed onto the Earth-facing port of the ISS's Harmony module by ground experts at mission control in Houston and bolted into place via commands by the ISS crew. But the capsule ran into troubles with its thrusters shortly after launching on Friday from Cape Canaveral, Florida, triggering the delay. "SpaceX said it has high confidence there will be no repeat of the thruster problem during rendezvous, including its capability to perform an abort, should that be required," NASA said. The delay will not affect the capsule's splashdown, which remains planned for March 25, the US space agency says. Dragon is carrying 544kg of supplies on SpaceX's second resupply mission to the ISS. In May 2012, SpaceX made history when Dragon became the first commercial spacecraft in history to successfully attach to the International Space Station. Previously only four governments - the United States, Russia, Japan and the European Space Agency - had achieved this challenging technical feat. SpaceX has now begun regular missions to the Space Station, completing its first official resupply mission in October 2012.
