Aug. 20, 2001 By Steven Siceloff FLORIDA TODAY CAPE CANAVERAL - The Expedition Two crew checked under the figurative beds and in the drawers to make sure they had everything as shuttle Discovery prepared to leave space station Alpha and its new residents Monday. Pat Forrester completed one of the last tasks Sunday, moving the 20-foot-long cargo cylinder known as Leonardo off the outpost and back into the shuttle's payload bay. Inside Leonardo was more than a ton of used gear, completed experiments and trash. Forrester was taken aback by his first excursion outside the shuttle. "They can't prepare you for ... just how beautiful the Earth looks from outside the shuttle," Forrester said. Astronaut Dan Barry, Forrester's partner on the spacewalks, had seen the Earth from inside a spacesuit before, but was unsure what to expect from the space station that has grown exponentially from the two small modules he visited in 1999. "The sheer size is amazing," he said. "You truly feel like you are climbing a mountain (or the) side of a building." During his previous spacewalk, Barry said it was no problem figuring out where on the station he was. This time, the station's additional modules and jutting solar arrays made navigation trickier. Discovery's four crewmen plus the station's former crew will depart Alpha at 10:52 a.m. today, leaving Expedition Three commander Frank Culbertson and his Russian crewmates Vladimir Dezhurov and Mikhail Tyurin behind. After springing a small test satellite from the cargo bay today, the astronauts and one cosmonaut will spend Tuesday preparing the orbiter for Wednesday's 12:48 p.m. landing at Kennedy Space Center.
