* All-ham ISS crew to undertake "unprecedented" spacewalk series: The
all-ham crew of the International Space Station will undertake what NASA is
calling "an unprecedented series" of four spacewalks during the next few
weeks. Expedition 14 Commander Mike Lopez-Alegria, KE5GTK, and Flight
Engineer Suni Williams, KD5PLB, will kick off the spacewalk string January
31 with a six-and-a-half-hour excursion. Subsequent spacewalks are set for
February 4 and 8 using US spacesuits. Lopez-Alegria and Flight Engineer
Mikhail Tyurin, RZ3FT, will conduct the fourth spacewalk later in February
using Russian spacesuits. NASA says the US spacewalks will bring on line new
portions of the station's cooling system, expanded with components activated
during the December space shuttle mission. Among other tasks, Lopez-Alegria
and Williams also will assist in the retraction of heat-rejecting radiators
on the station's P6 truss, install some external devices to stow cargo and
install cabling for a new power transfer system for future shuttle flights.
On the fourth spacewalk, Lopez-Alegria and Tyurin will remove a stuck
antenna from the Russian Progress 23 cargo spacecraft to ensure it can
safely undock in April. NASA TV <http://www.nasa.gov/ntv> will cover these
events. -- NASA
