TO VIEW IMAGE GO TO:
> HOUSTON - The crew members aboard the International Space Station
> spent this week finalizing handover operations, conducting
> experiments and preparing for the departure of the Expedition 14
> Expedition 14 Commander Michael Lopez-Alegria and Flight Engineer
> Mikhail Tyurin, accompanied by Spaceflight Participant Charles
> Simonyi, are targeted to touch down in central Kazakhstan in their
> Soyuz spacecraft at 7:30 a.m. CDT Saturday, April 21, one day later
> than originally planned.
> The primary landing site is too wet for landing operations due to the
> spring thaw. The one-day delay in departure from the station will
> allow for touchdown in a landing zone further to the south.
> The landing will conclude a 215-day flight for Lopez-Alegria and
> Tyurin and mark the longest single flight by an American astronaut.
> Live coverage of the landing operations will begin on NASA TV on
> Saturday at 12:30 a.m. for hatch closing, will return at 3:45 a.m.
> for undocking, and will resume at 6:15 a.m. for the deorbit burn and
> Crew members held a ceremony Tuesday afternoon marking the change of
> command of the station from Lopez-Alegria to Expedition 15 Commander
> Fyodor Yurchikhin. Yurchikhin and flight engineers Oleg Kotov and
> Suni Williams are now officially established on board the station.
> Williams, who served as an Expedition 14 crew member since December,
> will provide Expedition 15 with an experienced flight engineer for
> the early part of its mission.
> On Monday, Williams became the first person to run a marathon in
> space. Williams, an accomplished marathoner, was an official entrant
> in the Boston Marathon and ran the 26.2 mile race on a station
> treadmill in the Zvezda module, circling Earth at least twice in the
> process. Williams' run coincided with the tens of thousands of people
> running on the ground. She completed her marathon with an official
> time of 4:23:10.
> Russian specialists are preparing plans to repair the Condensate Feed
> Unit in the Russian system that processes condensate recovered in the
> U.S. segment of the station into potable water. Since the unit failed
> over the weekend, the supply of drinking water has been decreasing
> faster than the replenishment rate. Even if they are unable to repair
> the unit, enough water already is onboard to last until the ISS
> Progress 25 cargo vehicle docks in mid-May, providing a new supply of
> Also this week, Lopez-Alegria completed his final session with the
> Anomalous Long-Term Effects in Astronauts' Center Nervous System
> (ALTEA) experiment, which investigates the phenomenon of crew members
> seeing flashes of light while in orbit. Using an instrumented helmet,
> the experiment measures the cosmic radiation that passes through a
> crew member's head, brain activity and visual perception. ALTEA
> should help researchers better understand what levels of cosmic
> radiation crew members are exposed to and develop countermeasures for
> future long-duration spaceflights.
> Lopez-Alegria and Williams also worked on an Education Payload
> Operations activity linked to the International Polar Year. The crew
> members videotaped their Earth photography activities and their
> observations of sea ice and auroras. These images will be used later
> in NASA education videos sent to classrooms around the world.
> Education Payload Operations include curriculum-based activities that
> demonstrate basic principles of science, mathematics, technology,
> engineering and geography. They are designed to support the NASA
> mission of inspiring the next generation of explorers.
> The next station status report will be issued Saturday after
> Expedition 14's landing, or earlier if events warrant.
