Carol Frilegh said:With Food Low, Space Crew Must Cut Back

WASHINGTON, Dec. 9 - The two astronauts aboard the International Space
Station have been asked to curb their calories because of a food
shortage, NASA officials said Thursday.Supplies of food and water on the station have fallen so low that if a
Russian cargo vessel scheduled to arrive on Dec. 25 has a mishap or is
significantly delayed, the astronauts, one American and one Russian,
will have to abandon the station and return home months ahead of
schedule, the NASA officials said.The space station manager at NASA, William Gerstenmaier, said the
situation was manageable if nothing unexpected occurred. But Mr.
Gerstenmaier said juggling consumable items like food, water and even
light bulbs had been a challenge since the space shuttles were grounded
because of the Columbia disaster in 2003."This is not easy and requires lots of compromises," he said at a
televised news conference at the Johnson Space Center in Houston.The coming delivery by the robotic Progress cargo craft, loaded with
extra food and water, "is very critical," he said, adding, "There's no
question about that."Plans are being put together for the crew to leave, Mr. Gerstenmaier
said, in the event that the Progress is destroyed at launching or
cannot dock with the station for some other reason.At that point, he said, the station will have 7 to 14 days' worth of
food, at current consumption rates, and the crew will begin shutting it
down for a departure early next month on its Soyuz rescue craft.The mission flight director, Annette Hasbrook, said the station could
be safely left unstaffed for months, though it has been left empty so
far only for spacewalks. Such an action would require shutting off some
equipment, closing internal hatches and setting up the electronics so
the station could be controlled from Earth. With the grounding of the
American shuttle fleet since the Columbia disaster on Feb. 1, 2003, the
station lost its major source of supplies.Shuttles regularly flew to the outpost with tons of food, water,
equipment and experiments, as well as new crew members. Without
shuttles, the station has had to rely exclusively on Russian Soyuz
craft to deliver exchange crews and Progress cargo ships, which can
carry about two and a half tons of material, about a third of what a
shuttle can deliver.To conserve supplies, the 16 nations involved in the project agreed to
reduce crews to two astronauts from three. The latest crew, the
American commander, Dr. Leroy Chiao, and Col. Salizhan S. Sharipov of
the Russian Air Force, the flight engineer, arrived in mid-October,
expecting to stay for six months.Mr. Gerstenmaier said officials liked to keep a 45-day reserve of food
and water and had been close to that reserve several times while
awaiting Progress resupply flights. Before the latest crew was sent to
the station, managers realized that supplies would become low and
planned for that eventuality, he said.Dr. Sean Roden, the astronauts' flight surgeon, said the crew would not
be asked to go on drastic diets. By changing meal plans, Dr. Roden
said, managers want them to reduce their normal intake of 3,000
calories by 5 percent to 10 percent while maintaining regular exercise
and work schedules.No restrictions are being imposed yet on drinking water; water supplies
are ample into mid-January, Dr. Roden said."They will still have the same nutritional balance they had before," he
added.Part of the current squeeze stems from delays by the Russians in the
latest Progress delivery, which was changed from November to the end of
this month, officials said, and some food had to be removed from a
previous delivery because of the need to carry spare parts for a
malfunctioning Russian oxygen generator.American and Russian station managers learned last week that the
current crew had started using reserve food weeks ahead of schedule.
The astronauts were asked to conduct three food inventories, which
confirmed that supplies were less than expected.Mr. Gerstenmaier said a team had been assigned to look into tracking
the food inventory at the station. Part of the problem is that food is
stored in several places in packets, he said, and the crew cannot
easily keep track of it.The next Progress delivery will include 180 gallons of water and enough
food to last two astronauts more than 100 days, NASA officials said.
Also aboard will be 12 pounds of new science experiments, along with
needed supplies like batteries, lighting and clothing.Mr. Gerstenmaier said there would also be room aboard the tightly
packed ship to include Christmas presents for the crew and "some fun
things, as well."New York Times
Sounds to me like they need to think about eating say, 2 pounds per day;
much easier to keep track of then attempting to balance caloric intake in a
semi-hostile environment.
