to place the vehicle in Passive Abort Mode". In this mode, Dragon is not executing any more orbital operations. Its thruster system was disabled and the solar panels were not deployed since the vehicle had not achieved its proper solar panels deployment attitude. "Dragon is programmed not to open its solar panels outside its proper attitude configuration to avoid contact with the second stage. This rule is in place for scenarios in which Dragon is not properly separated from the Falcon 9 booster. As time progressed, teams working at SpaceX Mission Control, MCC-X in Hawthorne, California, started assessments of the issue". During the early minutes and hours of the mission, the mission progress news came in bits, some of it over social media. An update from Elon Musk on Twitter clarified: Issue with Dragon thruster pods. System inhibiting three of four from initializing. About to command inhibit override. At 16:12 UTC, Elon Musk announced that a "command inhibit override" would be issued as the Dragon module was "about to pass over Australia ground station". Initially solar panels deployment was held "until at least two thruster pods are active". SpaceX Mission Control decided to proceed with solar deployment due to array temperatures while the spacecraft was not in active attitude control at 16:40 UTC: "Thruster pod 3 tank pressure trending positive. Preparing to deploy solar arrays". At 16:50 UTC, solar arrays had successfully been deployed on the Dragon spacecraft. Three of the four thruster pods on the Dragon spacecraft must be operational for berthing to be allowed with the International Space Station. After making corrections, SpaceX regained control of all four thruster pods and would be able to correct its course to the ISS. According to Elon Musk, "All systems green". NASA officials said that the spacecraft would not rendezvous with the ISS on 2 March 2013 as was originally planned. It would instead rendezvous on 3 March 2013. Dragon was grappled with Canadarm2 by NASA Expedition 34 commander Kevin Ford and NASA flight engineer Tom Marshburn at 10:31 UTC on 3 March 2013, and was berthed to the nadir (Earth-facing) docking port of the Harmony module at 13:56 UTC. Remainder of mission (3 to 26 March 2013) On 6 March 2013, the space station's Canadarm2 removed the grapple bars from Dragon's trunk. This event marked the first delivery of unpressurized cargo from a commercial spacecraft to the ISS. The spacecraft's
