Station assembly preparations, maintenance and science in microgravity.
The first EVA was on 7 November 2005 for 5 hours and 22 minutes. There were two main objectives, both of which were completed. The first was to install and set up a new camera on the P1 Truss which was later used in the installation of more truss segments. The second was to jettison the Floating Potential Probe which was a failed instrument, designed to measure the station's electrical potential and compare it to the surrounding plasma.
The second spacewalk took place on 3 February 2006 and lasted 5 hours and 43 minutes. The astronauts jettisoned an old Russian Orlan spacesuit, named SuitSat-1, that was equipped with a radio for broadcasts to students around the world. The suit reached the end of its operation life in 2004. They also retrieved the Biorisk experiment, photographed a sensor for a micrometeoroid experiment, and tied off the surviving umbilical of the mobile transporter.
While wake-up music is a tradition aboard space shuttle missions, the ISS crew generally use an alarm clock to wake up. Expedition 12 astronauts received a special treat on 3 November 2005 when Paul McCartney performed Good Day Sunshine and English Tea in a first ever concert linkup from the Arrowhead Pond in Anaheim, California on his US tour. The event was broadcast live on NASA TV.
