Kennedy Space Center – After overcoming a frightening thruster failure that could have spelled rapid doom on the heels of a breathtakingly beautiful launch, the privately developed Dragon spacecraft successfully berthed at the International Space Station (ISS) at 8:56 a.m. EST Sunday morning, March 3, 2013 thereby establishing an indispensable
American lifeline to the massive orbiting lab complex.
Expedition 34 crew members Kevin Ford and Tom Marshburn of NASA used the station’s Canadian supplied robotic arm to successfully grapple and capture Dragon at 5:31 a.m. March 3 as the station was flying 253 miles above northern Ukraine. Originally, Dragon capture was slated only about 20 hours after launch. The capture came one day, 19 hours and 22 minutes after launch. Ground controllers at NASA’s Johnson Space Center in Houston then commanded the arm to install Dragon onto the Earth-facing port of the Harmony module.
Dragon is loaded with 1,268 pounds (575 kilograms) of vital supplies and provisions to support the ongoing science research by the resident six man crew, including more than a ton of vital supplies, science gear, research experiments, spare parts, food, water and clothing.
NASA says that despite the one-day docking delay; the Dragon unberthing will still be on March 25 followed by a parachute-assisted splashdown in the Pacific Ocean off the coast of Baja California.
Dragon will spend 22 days docked to the ISS. The station crew will soon open the hatch and unload all the cargo and research supplies. Then they will pack the Dragon with 2,668 pounds (1,210 kilograms) of science samples from human research, biology and biotechnology studies, physical science investigations, and education activities for return to Earth.
