A SpaceX delivery full of Christmas goodies arrived at the International Space Station on Saturday, following a slight delay caused by a communication drop-out.
The Dragon capsule pulled up at the orbiting lab three days after launching from Cape Canaveral. Commander Alexander Gerst used the space station's big robotic arm to grab the cargo carrier, as the two craft soared 250 miles above the Pacific.
It took two tries to get the Dragon close enough for capture.
NASA called off the Dragon's first approach because of trouble with the communication network that serves the space station. Equipment failure in New Mexico for NASA's Tracking and Data Relay Satellite system resulted in a temporary loss of communication with the station. For safety, Mission Control ordered the Dragon to back up.
It was a successful take two — just an hour-and-a-half late — after NASA switched to another TDRS satellite.
The Dragon holds everything the station astronauts need for Christmas dinner, as well as mice and worms for science experiments, and more than 2270kg of station equipment.
The holiday food includes smoked turkey, green bean casserole, candied yams, cranberry sauce and fruitcake. There also are shortbread and butter cookies, with tubes of icing for decorating.
Three of the space station residents will be on board for Christmas; the other three will return to Earth on December 20. Until then, the station is home to two Americans, two Russians, one Canadian and Gerst, who is German.
It is the second space station visit for this recycled Dragon; it was there last year, too.
SpaceX has been making station shipments for NASA since 2012. This is its 16th delivery under contract.
Two other supply ships are attached to the space station: One Russian and the other sent by NASA's other commercial shipper, Northrop Grumman.
