Most of this equipment was later incorporated into the other three orbiters during out-of-service major inspection and modification programs. ""Endeavour"s upgrades include:  Modifications resulting from a 2005–2006 refit of "Endeavour" included:  "Endeavour" flew its final mission, STS-134, to the International Space Station (ISS) in May 2011. After the conclusion of STS-134, "Endeavour" was formally decommissioned. STS-134 was intended to launch in late 2010, but on July 1 NASA released a statement saying the "Endeavour" mission was rescheduled for February 27, 2011. "The target dates were adjusted because critical payload hardware for STS-133 will not be ready in time to support the previously planned 16 September launch," NASA said in a statement. With the "Discovery" launch moving to November, "Endeavour" mission "cannot fly as planned, so the next available launch window is in February 2011," NASA said, adding that the launch dates were subject to change. The launch was further postponed until April to avoid a scheduling conflict with a Russian supply vehicle heading for the International Space Station. STS-134 did not launch until 16 May at 08:56 EDT. "Endeavour" landed at the Kennedy Space Center at 06:34 UTC on June 1, 2011, completing its final mission. It was the 25th night landing of a shuttle. Over its flight career, "Endeavour" flew 122,883,151 miles and spent 299 days in space. During "Endeavour's" last mission, the Russian spacecraft Soyuz TMA-20 departed from the ISS and paused at a distance of 200 meters. Italian astronaut Paolo Nespoli took a series of photographs and videos of the ISS with "Endeavour" docked. This was the second time a shuttle was photographed docked and the first time since 1996. Commander Mark Kelly was the last astronaut off "Endeavour" after the landing, and the crew stayed on the landing strip to sign autographs and pose for pictures. STS-134 was the penultimate Space Shuttle mission; STS-135 was added to the schedule in January 2011, and in July "Atlantis" flew for the final time. After more than twenty organizations submitted proposals to NASA for the display of an orbiter, NASA announced that "Endeavour" would go to the California Science Center in Los Angeles. After low level flyovers above NASA and civic landmarks across the country and in California, it was delivered to Los Angeles International Airport (LAX) on September 21, 2012.
