Running ahead of time, the International Space Station Expedition 33 crew successfully captured and installed the SpaceX Dragon capsule onto the Earth-facing port of the ISS’s Harmony module. Commander Suni Williams and astronaut Akihiko Hoshide captured the commercial spacecraft with the station’s CanadArm2 robotic arm at 6:56 a.m. EDT, and Dragon was officially berthed at 9:03 am EDT.

“Looks like we’ve tamed the Dragon,” radioed Williams. “We’re happy she’s on board with us. Thanks to everybody at SpaceX and NASA for bringing her here to us. And the ice cream.”

“This is a big moment in the course of this mission and for commercial spaceflight,” said SpaceX CEO and Chief Technical Officer Elon Musk. “We are pleased that Dragon is now ready to deliver its cargo to the International Space Station.”

The hatch ~~will be opened tomorrow~~ was opened earlier than expected, today at 1:40 pm EDT and Dragon will be unloaded over the next several days. Later, they will be re-packing it full of items that will be coming back to Earth, as this spacecraft has the ability to return intact, instead of burning up in the atmosphere like the other resupply ships that come to the station. Dragon will spend 18 days attached to the ISS.

Dragon is carrying nearly 400 kg (882 pounds) of supplies to the orbiting laboratory, including 117 kg (260 pounds) of crew supplies, 176 kg (390 pounds) of scientific research, 102 kg (225 pounds) of hardware and several kg/pounds of other supplies, such as food, water and Space Station parts. There are also 23 student experiments from the Student Spaceflight Experiments Program (SSEP) involving 7,420 pre-college students engaged in formal microgravity experiment design, according to SSEP director Dr. Jeff Goldstein.

The special treat that Williams mentioned is on board a new freezer called GLACIER (General Laboratory Active Cryogenic ISS Experiment Refrigerator): Blue Bell ice cream, a brand that is a favorite of astronauts training at the Johnson Space Center. The freezer will hold experiments that need to be returned to Earth for further examination.

Dragon will return a total of 758 kg (1,673 pounds), including 74 kg (163 pounds) of crew supplies, 392 kg (866 pounds) of scientific research, and 235 kg (518 pounds) of vehicle hardware and other hardware.
