Two astronauts performed the first in a series of spacewalks Friday to repair an International Space Station instrument. Andrew Morgan and Luca Parmitano started the spacewalk at 6:39 am EST (1139 GMT), which lasted six hours and 39 minutes. The two started work to repair the Alpha Magnetic Spectrometer, an instrument on the station's truss whose cooling system is failing. The two astronauts were able to complete all their planned tasks to prepare the instrument for repairs, and completed a number of get-ahead tasks originally scheduled for the second spacewalk. NASA expects four spacewalks will be needed to replace the instrument's cooling system.
