NASA cargo headed for ISS aboard Dragon spacecraft.
The upgraded two-stage Falcon 9 launch vehicle (version 1.1) is a heavier rocket with increased performance capability, redesigned first-stage, upgraded Merlin engines, upgraded avionics and software.
At the time of launch, the space station was traveling at an altitude of 260 miles over southeastern Turkey.
Dragon will be grappled at 7:14 a.m. on Sunday, April 20 by Expedition 39 Commander Koichi Wakata of the Japan Aerospace Exploration Agency. He will use the space station's robotic arm to take hold of the spacecraft. NASA's Rick Mastracchio will support Wakata in a backup position. Dragon is scheduled to depart the space station May 18 for a splashdown in the Pacific Ocean west of Baja California, bringing with it nearly 3,500 lb of science, hardware, crew supplies and spacewalk tools from the space station.
