Space Shuttle Endeavour Returns to Earth After Final Mission

by

CAPE CANAVERAL, Fla. — In the dark, early morning hours, NASA’s Space Shuttle Endeavour landed for the final time June 1, ending its last space mission and returning to Earth for good.

Endeavour, the youngest shuttle in NASA’s orbiter fleet, touched down here at Kennedy Space Center at 2:34 a.m. EDT, wrapping up a demanding 16-day mission to the international space station. After traveling  196 million kilometers during the course of 25 missions, Endeavour’s wheels rolled to a stop for the final time on Runway 15 at the Florida spaceport’s Shuttle Landing Facility.

“Welcome home, Endeavour,” Mission Control radioed the shuttle crew after landing.

“Thank you, Houston,” replied Endeavour commander Mark Kelly, adding that the shuttle is “really an incredible ship.”

“On behalf of my entire crew, I want to thank every person who’s worked to get this mission going and every person who’s worked on Endeavour,” he said. “It’s sad to see her land for the last time, but she really has a great legacy.”

The landing marked the end of NASA’s 134th shuttle mission since flights began in 1981. It was NASA’s second-to-last shuttle mission with only the final voyage of Atlantis remaining before NASA shuts down its space shuttle program after 30 years of service.

Endeavour launched on its 25th and final mission May 16 to deliver a $2 billion astrophysics experiment, called the Alpha Magnetic Spectrometer, and extra supplies to the international space station. The orbiter spent 11 days, 17 hours and 41 minutes parked at the orbiting outpost.

“We are very proud of Endeavour’s legacy, and this penultimate flight of the space shuttle program once again demonstrated the amazing skill and dedication of our astronauts and the entire workforce,” NASA Administrator Charles Bolden said in a statement after the shuttle landed. “As we begin the transition from the shuttle program to the commercial transportation of our crews and cargo, our ability to tackle big challenges remains steadfast and will ensure that NASA reaches even more destinations farther in the solar system.”

Shuttle commander Kelly, pilot Greg H. Johnson and mission specialists Greg Chamitoff, Mike Fincke, Andrew Feustel and Roberto Vittori delivered and installed the Alpha Magnetic Spectrometer on the exterior of the station’s starboard truss. The particle-physics detector will measure high-energy cosmic rays and search for signs of antimatter and mysterious dark matter in the universe.

“We got the Alpha Magnetic Spectrometer installed, which is a remarkable thing for physics and for science,” Kelly said before Endeavour undocked from the space station. “We’re looking forward to hearing what those discoveries are.”

The crew performed four spacewalks to make upgrades to the station. The fourth and final outing marked what is expected to be the final spacewalk ever taken by members of a shuttle crew.

On its last trip into space, the orbiter tacked more than 9 million kilometers onto its odometer, bringing the shuttle’s total distance traveled to more than 196 million kilometers.

 

Endeavour’s legacy in space

NASA’s space shuttles have played instrumental roles in the construction of the space station, and Endeavour made 12 visits to the orbiting complex in 25 flights. The shuttle delivered and attached the station’s first U.S. segment, the Unity node, in December 1998.

Endeavour went on to haul up crucial segments of the station, including sections of the backbone-like truss, solar arrays, the Tranquility module, Cupola observatory and most recently the Alpha Magnetic Spectrometer.

Now that Endeavour is on the ground again, the shuttle will begin the next, Earth-bound, phase of its career: being prepared for public display at a museum.

Four institutions across the country were selected by NASA to display Discovery, Atlantis, Endeavour and the test vehicle Enterprise, following the retirement of the agency’s shuttle program.

“It’s very bittersweet,” pilot Johnson said in an in-flight interview. “I just love this vehicle. I fell in love with this vehicle the first time I got to fly, three years ago on STS-123. She’s performed absolutely magnificently. This vehicle is a wonderful machine and it’s an honor and a privilege for each one of us to be a part of her final flight.”

Endeavour has been promised to the California Science Center in Los Angeles. The months-long decommissioning process after the shuttle lands will make sure Endeavour is properly decontaminated and safe for the exhibit.

Discovery will find a home at the Smithsonian Air and Space Museum in Washington; Atlantis will be showcased at the visitor center at Kennedy Space Center; and Enterprise will be moved to the Intrepid Sea, Air & Space Museum in New York.
