Time-lapse video: Falcon 9 positioned for 2nd launch attempt

Two astronauts working outside the International Space Station Wednesday installed a European Space Agency data relay antenna and connected four of six cables to partially power a new ESA experiment platform. They also removed two solar array handling fixtures to clear the way for a future power system upgrade.

Up to 24 launches are planned from Cape Canaveral in 2015, thanks to jam-packed manifests for SpaceX and United Launch Alliance to send up satellites for the U.S. military, NASA and commercial telecom operators.

SpaceX’s tenth launch of the year took off Tuesday from California’s Central Coast on a unique ridehsare mission to add satellites to Iridium’s communications network and replace two Earth science satellites which ended their observations last year.
