Adios, ISS

Dragon bids goodbye to the International Space Station. The next SpaceX commercial resupply mission is scheduled for launch at the end of September. SpaceX, founded in 2002 by billionaire entrepreneur Elon Musk, builds low-cost rockets and spacecraft and is one of just two private spaceflight companies NASA has contracted for unmanned cargo delivery missions to the International Space Station. The other is Virginia-based Orbital Sciences. This mission marked the second in a series of at least a dozen commercial space station resupply missions under a $1.6 billion NASA contract.

Now, THAT's a view

The SpaceX Dragon capsule is the only space station cargo craft designed to bring cargo back to Earth, a capability that was lost when NASA's space shuttle fleet was retired in 2011.

Hovering above Earth

A sight to behold: The Dragon, hovering above the Earth, photographed from the ISS. Later, flight engineer Tom Marshburn would capture the Dragon when it was 32 feet away from the station with the Canadarm2. Ground controllers subsequently assumed responsibility for operating the Canadarm2 and berthed Dragon to the space station.

Dragon capsule

The capsule was docked for about three weeks at the space station.

Liftoff

Hoisted into space March 1, 2013, by its Falcon 9 rocket, the Dragon spacecraft heads toward the International Space Station. It turned out to be a successful mission, though not without momentary drama after Dragon separated from Falcon 9’s second-stage. At that point, SpaceX engineers identified what was described as a minor issue with some of Dragon’s oxidizer tanks. The problem was corrected within a few hours.

During theSpaceX resupply last October, one of the engines in the Falcon 9 rocket malfunctioned at launch, prompting the flight computer to shut it down.
