Space Station (ISS) Status 6/29/07
After the departure of the space shuttle Atlantis, Expedition 15 Commander Fyodor Yurchikhin and Flight Engineer Oleg Kotov returned to their daily operations aboard the International
Space Station this week, while newly arrived Flight Engineer Clay
Anderson began conducting scientific experiments.
Atlantis landed in California June 22, 2007, after delivering a new starboard
truss segment and a set of solar arrays to the station. Returning on
the shuttle was Sunita Williams, who lived and worked aboard the
orbiting complex for six months. Anderson succeeded Williams on the
station and arrived with the Atlantis crew on June 10.
Anderson performed his first Saturday Science activity on June 23,
showing younger television viewers how Newton's laws apply to sports
activities, even in the microgravity of space.
On Monday, Anderson began work with a nutrition experiment. He
collected blood and urine samples and began logging all of the food
and drinks he consumed. The experiment tracks many vitamins and
minerals essential for good health. It is the most comprehensive
in-flight study to date of human physiological changes during
long-duration spaceflight. Also, Anderson and Kotov did a medical
emergency exercise, and Yurchikhin replaced one of three transmitters
on the Russian Regul communications system.
The crew inspected the lights and power systems and performed a
routine examination of the windows on the Russian Zvezda service
module on Tuesday.
Wednesday was filled with science. Each crew member completed medical
tests and periodic fitness evaluations, and worked with a variety of
Russian experiments. Kotov spent about two hours using a multimeter
to do resistance checks on the computer system in the Zvezda service
module. The two major computer systems there continue to function
well, with two of three "lanes," or data paths, of each system
Anderson wore an acoustic dosimeter on Thursday to check station noise
levels. He also worked with the Microgravity Science Glovebox in an
unsuccessful effort to complete a leak check. Troubleshooting
continues. Yurchikhin and Kotov spent more than two hours with the
Russian Profilaktika experiment, which looks at measures to
counteract the long-term effects of microgravity. Yurchikhin also
worked with the Matryoshka radiation detection experiment and Kotov
inventoried medical equipment inventory.
On Friday, Anderson did a routine cleaning of spacesuit cooling loops.
Yurchikhin and Kotov worked in the Russian segment, replacing current
converter units in the Zarya module.
