A new crew is poised to launch to the International Space
Station early Sunday to help outfit the laboratory for double-sized occupancy.
Expedition 18 commander Michael Fincke and flight engineer
Yury Lonchakov are scheduled to launch aboard a Soyuz TMA-13 spacecraft from
the Baikonur Cosmodrome spaceport in Kazakhstan Sunday at 3:01 a.m. EDT (0701
GMT). Set to join them on the journey is space tourist Richard
Garriott, the first American second-generation spaceflyer. His father,
former NASA astronaut Owen Garriott, will be watching the launch from the
ground at Baikonur.
Fincke and Lonchakov are set to begin a six-month stay
aboard the orbiting outpost, while Garriot is flying under a $30 million deal
between Russia's Federal Space Agency and the Vienna, Va.-based firm Space
Adventures. He is slated to return Oct. 23 aboard a Soyuz vessel carrying two
current space station crewmembers, Expedition 17 commander Sergei Volkov and
flight engineer Oleg Kononenko, home to Earth. Coincidentally, Volkov, son of
Russian cosmonaut Alexander Volkov, is also a second-generation space traveler.
Garriot, a a computer game developer from Austin, Texas,
will be the 6th space tourist to fly in space. He plans a packed schedule of
science experiments for his roughly 10-day trip. His father, who flew on the Skylab
3 mission in 1973 and rode aboard the shuttle Columbia's STS-9 trip in 1983,
will serve as chief scientist for his son's mission.
Fincke
and Lonchakov are both veteran astronauts: Fincke served as flight engineer
on 2004's Expedition 9 mission to the International Space Station (ISS, while
Lonchakov rode aboard the space shuttle Endeavour's STS-100 mission in 2001,
and a Soyuz flight to the station in 2002. Lonchakov, chief cosmonaut at
Russia's Yuri Gagarin Training Center, will serve as commander of Sunday's
Soyuz trip.
When the trio arrive at the space station, there will be no
working toilet aboard. The lone facility at the station broke
on Thursday, forcing the current crew to use the toilet aboard the Soyuz
vehicle docked at the lab. When the new flight arrives, its crew use the potty
aboard their own Soyuz, if the toilet is still broken.
Space station expansion
The two are set to join NASA astronaut Greg Chamitoff, an
Expedition 17 flight engineer currently aboard the ISS, to help convert the
station to host
six-person crews, expanded from its current crew compliment of three.
"It's exciting to be on the 18th
expedition to our beautiful space station, and we are right at the cusp of
going from a three-person crew to a six-person crew," Fincke said in a NASA
preflight interview. "Our crew, Expedition 18, we are ready to make that
transition. It's going to require several space shuttles to come up and give us
the missing pieces."
Some necessary supplies and equipment for the transition are
due to be launched aboard the space shuttle Endeavour's STS-126 flight in
November, and Discovery's STS-119 mission in early 2009. Endeavour is also
scheduled to ferry new Expedition 18 flight engineer Sandra Magnus to the
station, and carry Chamitoff home. Magnus is slated to be replaced by Japanese
Aerospace Exploration Agency astronaut Koichi Wakata, arriving on next year's
Discovery flight.
To get the station ready to accommodate more people, the
Expedition 18 crewmembers will help install new sleeping cabins, new kitchen
equipment, a new toilet (to supplement the current balky one), and a machine to
recycle urine into drinkable water.
"On one hand, the engineer in me says it's probably purer
water than most we've ever drunk before, but on the other hand it's still kind
of funny to know where that water's been," Fincke said. "But we're a close
crew."
Fincke and Lonchakov are also scheduled to perform a
spacewalk in Russian-built Orlan spacesuits in late December to install new
science experiments.
"The name of the hardware is Explorer Impulse; it is
intended for geophysics studies, for measuring velocity of charged particles,
for defining parameters of the ambient environment around the station,"
Lonchakov said. "So our objectives are very interesting. They are substantial
but feasible."
The crew will also be involved in many science experiments
during their stay in space, with a heavy focus on life sciences research that
can help pave the way for future manned space exploration missions.
"Those experiments address different biological processes
that take place in zero gravity, how zero gravity impacts the habitable
environment, plants, animals, those life forms that are expected to be used for
future interplanetary flights to moon and Mars," Lonchakov said.
One such project will study a Russian device called a
braslet (meaning "bracelet") that can be used to gently restrict the flow of
blood in astronauts' legs, and could make the transition to the microgravity
environment of space more comfortable.
The Expedition 18 crew is set to launch into space on
Sunday, Oct. 12 at 3:01 a.m. EDT (0701 GMT). NASA will broadcast the launch
live via NASA TV. Click here for
