Watch conditions at Kennedy Space Center during Tropical Storm Isaias

Two days after blasting off from NASA’s Kennedy Space Center in Florida, SpaceX’s refurbished Dragon supply ship arrived at the International Space Station on Monday with nearly 6,000 pounds of experiments and equipment. Grapple of Dragon by the station’s robot arm occurred at 9:52 a.m. EDT (1352 GMT).

Officials from NASA and SpaceX briefed the media on Monday’s scheduled launch of a commercial Dragon spacecraft on an automated resupply mission to the International Space Station. It will be the 12th SpaceX cargo flight to the research outpost.

NASA is sending into orbit Monday night a spacecraft to test a safer type of rocket fuel, an ultra-precise atomic clock that could change the way missions navigate in deep space, and an experiment to examine the resiliency of electronics to radiation.
