Station assembly preparations, maintenance and science in microgravity.
[edit] Spacewalks
There have been two spacewalks outside the ISS during Expedition 12. MacArthur and Tokarev participated in both of them.
[edit] EVA 1
The first EVA was on November 7, 2005 for 5 hours and 22 minutes. There were two main objectives, both of which were completed. The first was to install and setup a new camera on the P1 Truss which will be 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. [2]
[edit] EVA 2
The second spacewalk took place on February 3, 2006 and lasted 5 hours and 43 minutes. The astronauts jettisoned 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. [3]
[edit] Solar eclipse
On March 29, 2006 a total solar eclipse took place, and the picture to the right was taken by the Expedition 12 crew. It clearly shows the shadow of the Moon being cast on the Earth.
