Astronauts Complete Final Spacewalk For Shuttle Program

May 27, 2011

Astronauts aboard space shuttle Endeavour completed the final spacewalk for the space program.

Veteran spacewalkers Mike Fincke and Greg Chamitoff floated outside the International Space Station to finish-up the final space walk for Endeavour’s 16-day mission.

The 7 hour 24 minute spacewalk’s primary objectives included stowing the 50-foot-long boom and adding a power and data grapple fixture to make it the Enhanced International Space Station Boom Assembly.

The total time the spacewalkers spent floating outside the ISS during this mission was 28 hours and 44 minutes.

NASA said the two astronauts surpassed the 1,000th hour astronauts and cosmonauts have been spacewalking in support of space station assembly and maintenance.  This was the 159th spacewalk in support of station assembly and maintenance and the 248th spacewalk U.S. astronauts have conducted overall.

Fincke has now spent 48 hours and 37 minutes floating around outside spacecrafts, and Friday evening he will become the U.S. astronaut who has spent the most number of days in space.

During the STS-134 mission, the Endeavour crew delivered the Alpha Magnetic Spectrometer (AMS) and spare parts including the two S-band communications antennas, a high-pressure gas tank and additional space parts for Dextre. 

Endeavour is scheduled to land back at the Kennedy Space Center on Wednesday.
