spacetoday.net: NASA working to schedule AMS, battery repair spacewalks

NASA is still figuring out how to squeeze in three spacewalks some time in the next two months to complete station repairs. NASA has one more spacewalk remaining to wrap up the replacement of the cooling system on the Alpha Magnetic Spectrometer instrument, along with two spacewalks to complete replacement of batteries for the station's power system, work that started in October but was put on hold after a battery charging unit malfunctioned. With a busy schedule of visiting vehicles this month, NASA is aiming for a narrow window in January to perform the spacewalks. That window will close in early February when the station's crew drops to three.
