SpaceX’s Dragon spacecraft has splashed down safely in the Pacific
Ocean, marking the successful completion of its mission in which a
number of historic firsts were achieved. The splashdown came at
approximately 11:42 US EDT, with the unmanned capsule landing in the
waters roughly 500 miles (805 km) off the coast of Baja, California.
After its launch on May 22 atop a Falcon 9 rocket, the Dragon capsule became the first commercial spacecraft to dock with the International Space Station (ISS) on May 25. While attached to the ISS,
1,146 pounds (520 kg) of non-critical cargo that included food, other
crew provisions and student experiments were unloaded, making room for
the 1,455 pounds (660 kg) of cargo that was then packed onto the
spacecraft to be returned to NASA. With other cargo vehicles servicing
the ISS all destroyed after leaving the ISS, the reusable Dragon
spacecraft is the only one capable of returning significant amounts of
cargo to Earth.
While the journey to the ISS took 3 days, 6 hours, 11 minutes and 23
seconds, the return trip, from detaching from the ISS to splashing down
in the Pacific Ocean, took just under six hours. After detaching from
the ISS’s robotic arm at 5:49 am US EDT, a deorbit burn was carried out
at 10:51 to decelerate the spacecraft. At 11:36, the spacecraft’s chutes
were deployed and it splashed into the ocean six minutes later,
awaiting recovery by boat.
