Aug. 23, 2001 Discovery returns crew from Alpha Perfect landing ends mission By Steven Siceloff FLORIDA TODAY CAPE CANAVERAL - Discovery glided smoothly out of a cloudy sky Wednesday afternoon, then lifted its nose and gracefully touched down on Kennedy Space Center's shuttle runway. The flawless landing ended a 12-day mission to space station Alpha for four of the astronauts and wrapped up 167 days in space for the three others. The crew got an extra 90 minutes in space because a bank of stubborn clouds blossomed in the morning, blocking the shuttle's first try. Rain disappeared and the cloud bank evaporated in time for a 2:23 p.m. touchdown. On the way down from space, Discovery commander Scott "Doc" Horowitz and astronaut Dan Barry said they got a feel for how fast they were going as they got closer to Earth. "The thing that strikes you first is at these kinds of speeds, the world is going by in a real big hurry," Horowitz said. "There's Houston, there's New Orleans, OK, now turn left."Russian cosmonaut Yury Usachev and astronauts Jim Voss and Susan Helms rode on Discovery's lower level, with their backs to the floor and their feet resting in lockers. The three have spent the past five months living aboard Alpha. Terry Taddeo, NASA flight surgeon, said the reclined position keeps blood from pooling in their feet as gravity takes hold of them for the first time in five months. The three were told to move their heads around a lot as Discovery made its way home to get their body's balance senses back in shape. "They don't have as much blood on board as you or I would," Taddeo said, explaining that in weightlessness, the human body does not need as much blood as on Earth, so the body doesn't replenish its supply as quickly. Soon after Discovery came to a halt on the runway, a bus similar to the "people movers" seen at airports drove out and raised an air-conditioned room up to the hatch. NASA and Russian Space Agency doctors were on hand to help the crews out of the orbiter and see how they adjusted to gravity. After several hours of medical tests Wednesday, Horowitz said the Expedition Two crewmembers would get to eat some of their favorite foods, including hamburgers, salads and real coffee and cheese. "They're cooking them over in the crew quarters right now," Horowitz said. Most heartwarming to the shuttle crew was the reunion the station residents had with their families shortly after landing. "It really struck me what we had done on this mission," Horowitz said.Horowitz, pilot Rick Sturckow and astronauts Barry and Patrick Forrester climbed out of Discovery with little problem and looked around the orbiter while Usachev, Voss and Helms waited inside the bus. "It's a little warm," Horowitz joked while touching Discovery's nosecone. The area heats up to more than 2,300 degrees during the orbiter's plunge into the atmosphere. The crew will fly back to Houston today. The former station residents will begin weeks of rehabilitation. Usachev will spend several days in Houston before returning to Star City, Russia for the rest of his reconditioning. The landing ended an 11-month phase of the International Space Station program that saw eight shuttle missions add segments to the outpost and carry astronauts and cosmonauts to live aboard it. The outpost grew from two sections of less than 60 feet to more than 120 feet that on Earth would weigh 280,000 pounds and stand 12 stories high. The living space is about the same as a three-bedroom house. The project has run into significant difficulties in the past year, with its costs ballooning another $4.8 billion. NASA Administrator Dan Goldin said minutes after the landing that the program would be a success. "We're going to solve all the station problems," he said, pointing out that other countries may build a living quarters and escape ship to let the station host six or seven crewmembers at a time. "We've cancelled nothing. We're NASA, we don't shrink from problems." Discovery will now be grounded for more than a year so the ship can undergo a series of inspections and some modifications. The work is expected to be done at Kennedy Space Center instead of at the Boeing plant in Palmdale, Calif., where the shuttle was built. It will mark the first time since 1992 that the intense work will be done in Florida. Goldin said the agency is still making its final plans for Discovery, and its trying to decide the best way to schedule its shuttle fleet for maintenance.
