CAPE CANAVERAL, Fla. -- The crew of space shuttle Endeavour's STS-134 mission to the International Space Station participates in a news conference in the Press Site auditorium at NASA's Kennedy Space Center in Florida on landing day. From left are STS-134 Commander Mark Kelly, Pilot Greg H. Johnson, Mission Specialists Michael Finke, Roberto Vittori, astronaut with the European Space Agency and Andrew Feustel. Endeavour's final return from space completed the 16-day, 6.5-million-mile STS-134 mission. Main gear touchdown was at 2:34:51 a.m. EDT, followed by nose gear touchdown at 2:35:04 a.m., and wheelstop at 2:35:36 a.m. Endeavour and its crew delivered the Alpha Magnetic Spectrometer-2 (AMS) and the Express Logistics Carrier-3 (ELC-3) to the International Space Station. AMS will help researchers understand the origin of the universe and search for evidence of dark matter, strange matter and antimatter from the station. ELC-3 carried spare parts that will sustain station operations once the shuttles are retired from service. STS-134 was the 25th and final flight for Endeavour, which spent 299 days in space, orbited Earth 4,671 times and traveled 122,883,151 miles. Photo credit: NASA/Jim Grossmann
