Part of the 30th full-time crew of the International Space Station lifts off from Russia’s Baikonur Cosmodrome aboard Soyuz TMA-03M. Oleg Kononenko, André Kuipers and Donald Pettit take up residence on the ISS for 194 days, becoming part of the Expedition 29/30 crews. All three return to Earth in July 2012 aboard the same vehicle.
For the first time since a failed Dragon capsule launch to the International Space Station in June, SpaceX launches its Falcon 9 rocket with a payload of 11 OrbComm mini-satellites. After the second stage separates to go on to successfully deploy the OrbComm satellites, the first stage performs three engine burns to return for a stable landing. For the first time (after two previous attempts on oceangoing unmanned barges), the Falcon 9 drops to a gentle landing at a designated landing zone at Cape Canaveral, potentially paving the way for rockets whose first stages can return home for refurbishing and relaunch.
