French astronaut Sophie Adenot began a second spacewalk at the International Space Station on Tuesday, as she and NASA astronaut Anil Menon were set to continue work on a space-to-ground communications antenna. Adenot, a European Space Agency astronaut, was scheduled to help Menon retrieve and install a spare antenna on the station’s Z1 truss, above the Unity module, and make electrical and data connections to restore high-speed communications with mission control.
