Canadarm captures unmanned Dragon capsule
Canada’s robotic arm on the International Space Station was put to work today when it grabbed a Dragon capsule that arrived at the orbiting space lab.

Well the launch went well, then a glitch with some thrusters. They get purged and work, and just a day delay before the OK to get close enough for the Canadarm2 to grapple and tuck into an Earth facing port.

SpaceX Update: Dragon Now Mated to Space Station
By Phil Plait
Posted Sunday, March 3, 2013, at 12:17 PM
Well, that was fast! This morning, the SpaceX Dragon capsule was successfully berthed to the International Space Station. After all the drama that started this mission, the successful orbital mating brought cheers—and a sigh of relief—across NASA.
The capsule began maneuvering toward the ISS last night, and took several hours to approach. At 10:31 UTC (05:31 Eastern US time), when it was a few meters away, the astronauts used the Canadarm2—the station’s large, articulated robot arm—to grapple the capsule. After a few hours of checkouts, the arm brought Dragon in, and the capsule was berthed at 13:56 UTC (08:56 Eastern).

SpaceX Dragon successfully docks with International Space Station
Will spend the next 22 days attached to the ISS before returning.

After some issues with its thrusters hours after launch, the SpaceX Dragon capsule successfully docked with the International Space Station. NASA reported that the capsule attached to the Harmony module of the ISS at 8:56am EST Sunday morning, with the door set to be opened on Monday morning.
Dragon took off from Cape Canaveral on Friday morning and reached orbit without a hitch, but a pressure problem prevented the thruster pods from initializing once orbit was attained. The four pods then gradually came online over the course of the day. Two pods are needed to get Dragon to the ISS with a third pod necessary for successfully maneuvering once the station is reached.
Loaded with nearly 1,270 pounds of supplies (575kg, to be exact), Dragon will spend the next 22 days docked with the ISS. On its return, the capsule will carry more than 1,200 kg of cargo, according to NASA. Included in the return payload will be seedlings and metal mixtures that spent time in low gravity, along with biological samples taken from the crew.

Dragon is a free-flying, reusable spacecraft developed by SpaceX under NASA's Commercial Orbital Transportation Services (COTS) program. Initiated internally by SpaceX in 2005, the Dragon spacecraft is made up of a pressurized capsule and unpressurized trunk used for Earth to LEO transport of pressurized cargo, unpressurized cargo, and/or crew members.
In May 2012, SpaceX made history when its Dragon spacecraft became the first commercial vehicle in history to successfully attach to the International Space Station. Previously only four governments -- the United States, Russia, Japan and the European Space Agency -- had achieved this challenging technical feat. SpaceX has now begun regular missions to the Space Station, completing its first official resupply mission in October 2012.

BREAKING: After Initial Problems, SpaceX Dragon Now Looking Good On Orbit
By Phil Plait

Posted Friday, March 1, 2013, at 4:25 PM
To be clear, things are looking good now, and it looks like the mission will proceed. Just not quite as planned.
Launch, and the Emergence of the Problem
The launch, using the SpaceX Falcon 9 rocket, was essentially flawless. The rocket performed beautifully and was able to cleanly insert the Dragon capsule into the desired orbit
However, shortly thereafter there was a problem. The first indication was that the solar panels—which provide power to the capsule during the mission—did not deploy as they were supposed to, which should happen about 10 minutes into the flight. There is a battery onboard that can provide power for only 12—14 hours, so this was worrisome.
However, news soon came down that the thrusters on the capsule were not working; the tanks containing the oxidizer (used to ignite the fuel) were not pressurizing correctly. The thrusters are small rockets that can be used to change the orbit of Dragon as well as maneuver it on orbit. These are mission-critical: without them, the mission cannot proceed.

Sighs of relief.
Thanks for looking up with me.

Research Rides Dragon to the International Space Station
A second contracted flight for the SpaceX Dragon spacecraft to the International Space Station will be twice as nice for researchers working with investigations on the orbiting laboratory. While other cargo ships can bring research payloads to the station, only the Dragon and the Russian Soyuz can safely get the cargo home. Scientists in the United States, Canada, France and Japan -- and several high school students -- are awaiting the return of their research studying a wide range of subjects, from plants to liquid crystals.

Dragon Propulsion Anomaly Resolved After Successful Falcon 9 Launch (Updated 3/3/13)The fifth SpaceX Falcon 9 rocket orbited a Dragon spacecraft on NASA's CRS-2 International Space Station resupply mission on March 1, 2013, but Dragon suffered a problem shortly after reaching orbit. The initally unannounced problem occurred around the time that Dragon's solar arrays should have deployed, a process that occurs within minutes of spacecraft separation from the Falcon 9 second stage.
Falcon 9 lifted off from Cape Canaveral Space Launch Complex 40 at 15:10 UTC and provided an uneventful nine minute, two-stage ascent to orbit. Dragon, filled with 847.8 kg of ISS supplies and 201.8 kg of packing materials, separated into a 199 x 323 km x 51.66 deg orbit, and was visible moving away from the second stage in an initially stable fashion.
