Kristina Ferrero and Kyle Gaiser stow their gear in a small storage box and start running down the items on the checklists. They check their temperatures and lung capacity, then make sure all their equipment is working and in the right place.

Upstairs, their commander and the pilot of the space shuttle Enterprise are flipping switches in the cockpit, telling Mission Control what they鈥檙e doing at every step of the way.

Gaiser and Ferrero have just about completed their tasks when they get a gentle reminder.

鈥淵ou guys are probably going to want to sit down,鈥� the voice from the corner suggests. 鈥淵ou鈥檝e got 20 seconds to launch.鈥�

Ferrero and Gaiser won鈥檛 be going into orbit on this spring afternoon. Still, they鈥檒l be mimicking鈥攁s closely as possible鈥攚hat astronauts do when they go into space. The teenagers are spending a week at Space Camp, getting an education in what astronauts do and the history of space travel, and catching a glimpse of life inside a space shuttle.

鈥淵ou learn a ton,鈥� says Lindsey Dominico, a 9th grader from Roseburg, Ore., one of 38 students from that town here at camp this spring, along with Gaiser, who hails from New York, and Ferrero, from Vermont.

Earlier in the day, Dominico and Jayce Clawson, classmates at Roseburg鈥檚 Joseph Lane Middle School, sit in the same seats that Gaiser and Ferrero had occupied. The four teenagers, who live across the country from each other, met two years ago when they attended the Space Academy and met up again last month when they enrolled in the Advanced Space Academy for older students.

For this one-hour mock flight, Dominico dons a headset in the Mission Control room. 鈥淚t鈥檚 learning, but it鈥檚 also fun,鈥� she says of her three trips to Space Camp since 1999.

At Space Camp, kids of all ages鈥攆rom elementary school through adulthood鈥攇et a hint of what it鈥檚 like to be an astronaut. They use the same equipment that astronauts use to simulate floating in space. They spend their days together much as a team of astronauts do as they prepare for missions. They train to go on simulated missions. And they walk through them as well, flipping switches and talking on two-way radios much like pilots, mission specialists, or Mission Control operators would.

鈥淚t鈥檚 as close as you can get,鈥� says Aimee Tilson, who, like Dominico, is attending Space Camp for the third time.

Each year, more than 100 school groups come to Space Camp here at the U.S. Space & Rocket Center, a complex that includes a museum, an IMAX theater, and a courtyard filled with mammoth artifacts from the U.S. space program. From Interstate 465, visitors can find their way by driving toward the towering 363- foot-tall model of the Saturn V rocket, which propelled the Apollo missions to the moon.

Huntsville calls itself 鈥淎merica鈥檚 Space Capital.鈥� At the National Aeronautics and Space Administration鈥檚 research facility one highway exit away from the camp, teams of rocket scientists designed the technology for the space program that won the race to the moon. Today, NASA still operates that facility. The nonprofit center, although separate from NASA, works closely with the space agency to make the Space Camp experience as close as possible to the real thing. The space center gets most of its funding from student fees and also raises money from corporate sponsorships. The state of Alabama and NASA provide a small amount of money as well.

Aside from the learning environment, the Space & Rocket Center has all the requisite ingredients of a camp: a cafeteria that serves food people complain about; dorm rooms campers say are too crowded; and recreational activities that aren鈥檛 part of the typical school day, such as shooting off model rockets that campers assembled themselves.

The heart of the experience, though, is on the crowded floor with models of the Enterprise, the Endeavor, the International Space Station, and the mission-control centers running each of them.

The simulated missions are the highlight of campers鈥� experiences, but they are just a small part of it. Campers鈥� days are filled from wake-up till lights out with learning opportunities, team-building exercises, and training that prepares them to re-enact life on a space mission.

While these students simulate the space experience, the real-life space-shuttle program is in limbo as NASA investigators search for clues to the Feb. 1 breakup of the shuttle Columbia. The disaster may have put NASA in a holding pattern, but enthusiasm for space travel among campers hasn鈥檛 wavered.

鈥淚t kind of made me scared,鈥� says Sam Denney, a 7th grader at Winston Middle School in a district neighboring Roseburg. After being here the first time in 2001, he decided he wanted to be an astronaut. The Columbia鈥檚 demise didn鈥檛 change his career goal. But he says: 鈥淭he feeling that I might die up there kind of freaked me out.鈥�

And the calamity did solidify his desire to become a mission specialist instead of a commander or a pilot, who fly the vehicle. 鈥淚 don鈥檛 want to be in control of people鈥檚 lives,鈥� he says.

For Shawn Anderson, a 7th grader at Joseph Lane Middle School, Columbia鈥檚 fate confirmed his desire to work in NASA鈥檚 Mission Control rather than fly in a spacecraft. 鈥淎ll along, I wanted to be in Mission Control,鈥� says Anderson, who also came to Space Camp for the first time in 2001, 鈥渂ut that kind of finalized it.鈥�

The boys鈥� attitudes are similar to most Roseburg students鈥�, according to the trip鈥檚 organizer, Dan Tilson, Aimee Tilson鈥檚 father and a 6th grade teacher at Eastwood Elementary School.

鈥淓very one of the kids said: 鈥榊eah, it is a tragedy, but it shouldn鈥檛 stop us from exploring space,鈥� 鈥� says Tilson, who has been bringing groups here from Roseburg every other year since 1995. 鈥淲e take space travel for granted, but it鈥檚 a dangerous business. It鈥檚 kind of a hostile environment, and it鈥檚 never going to be 100 percent safe.鈥�

Space Camp officials say they haven鈥檛 noticed a decline in interest since the Columbia accident. In the first week of April, the Roseburg group and a school group from Chicago are here, as well as children who signed up for the experience on their own, like Ferrero and Gaiser.

It鈥檚 7:30 p.m. A team of 5th and 6th grade boys leaves a short and energetic game of four-square and heads toward the shuttle Pathfinder.

Even though it鈥檚 been more than 12 hours since breakfast, the boys鈥� day isn鈥檛 ready to end. They鈥檙e about to get a lesson on the space-shuttle program.

Suzanne Clayton, their counselor, leads them to the Pathfinder on display in the camp鈥檚 courtyard. Clayton is one of the many young adult counselors who lead campers through their morning-to-night program of learning, training, and mission simulations. Since the days are so long, each group starts the morning with one counselor and finishes in the evening with another.

Clayton tells the boys about the Pathfinder, the model of the shuttle that NASA used to design the airplane that sometimes ferries the shuttle across the country. Clayton reviews the function of each part of the craft鈥攖he booster rockets, the external fuel tank, and the orbiter. She quizzes students on all sorts of space facts: the name of the first woman to enter space; the name of the first U.S. woman to enter space; the name of the first American woman to pilot the space shuttle.

鈥淲ho is Christa McAuliffe?鈥� Clayton finally asks.

鈥淭he first woman pilot?鈥� one boy says hesitantly. Then, there鈥檚 silence.

鈥淒on鈥檛 you guys know who Christa McAuliffe is?鈥�

鈥淣o!鈥� comes the chorus.

Clayton starts telling the story of McAuliffe, the New Hampshire teacher-astronaut who died when the space shuttle Challenger exploded shortly after launch in 1986. That, like many of the U.S. space program鈥檚 historic moments, happened before this group was born.

The lesson is one reason the Roseburg public schools excuse 38 students from school for a week to attend space camp. They don鈥檛 visit during spring break, Tilson says, because Space Camp is a learning experience on a par with school. The trip is open to 5th graders and older students in the district鈥檚 12 schools who are willing to shell out tuition and airfare. This year, the bill ran $1,100 a camper, most of which is paid by families, although some students raise money on their own.

Before they trek from Oregon to Alabama, Tilson organizes monthly meetings where the students learn about the history of the space program and complete assignments. Every participant had to give a presentation this year on the accomplishments of one space mission.

Once the campers arrive in Huntsville, their days are filled with lectures about the science of rocketry and the early days of the space program鈥攗sually while sitting next to displays of those spacecrafts in the museum. They learn about the science that propelled the crafts into orbit, and even get quizzed on what they learned during the Space Bowl鈥攁n academic competition between teams in a game-show format.

鈥淚t鈥檚 really cool to learn about space,鈥� says Aimee Tilson. 鈥淚n school, you don鈥檛 really learn about it.鈥�

鈥淢ost of the stuff at school is review,鈥� says Shawn Anderson, the Joseph Lane Middle School 7th grader. 鈥淭his is all new stuff.鈥�

Sitting underneath the Pathfinder, the boys show that they actually did know a lot about Christa McAuliffe, even if they didn鈥檛 recognize her name. As Clayton starts to tell the story of the ill-fated mission, they interrupt her to fill in the blanks.

鈥淪he died in the Challenger,鈥� says Andrew Walkup, a 5th grader at Hucrest Elementary School.

鈥淎fter 79 seconds,鈥� adds Thaddeus Davis, a 5th grader at Rose Elementary School.

Back at the Enterprise鈥檚 Mission Control, Lindsey Dominico, Aimee Tilson, and a male classmate talk the Enterprise鈥檚 crew through their tasks.

Twelve television screens light up the room. One shows the pilot and the commander on the flight deck operating their craft. Another charts the shuttle鈥檚 course over the Atlantic Ocean, across southern Africa, and as it heads toward Australia.

Dominico talks through her headset to Kristina Ferrero and Kyle Gaiser as they simulate a space walk in the Enterprise鈥檚 cargo bay. Gaiser is attached to the shuttle鈥檚 robotic arm and positions himself next to a satellite. Dominico reads from a manual telling him which switches he needs to flip, first to deactivate the satellite, then repair and reboot it. Gaiser eventually tests the satellite so they see how it works.

The procedures are the same ones that Dominico conducted earlier in the day when she had the chance to wear a harness that allowed her to float about the cargo area. 鈥淚t was cool,鈥� she says. 鈥淵ou just kind of fell, and you were caught.鈥�

Aimee Tilson sits next to Dominico, switching headsets so Tilson can juggle two jobs. Because attendance in the Advanced Space Academy is low this week, Tilson鈥檚 responsible for monitoring the space shuttle to ensure it stays on time and for overseeing scientists in the space station. While the student- astronauts are conducting scientific experiments that include spinning in a chair and measuring the effects on their bodies, Tilson is keeping track of the safety of their vessel.

Once in a while, Tilson interrupts them. 鈥淗ey guys,鈥� she says, 鈥渄o you have a warning light?鈥�

A battery is losing its charge and needs to be replaced. She reads through manuals to help them fix it.

While this one-hour mission project is simple and mostly follows a script that counselors have written for them, Tilson and Dominico know tomorrow will be different. Then, they and the rest of their team will be on a six-hour simulated mission on the Enterprise.

On the prolonged mission, counselors will pose problems that are too complicated to be solved simply by looking at the manuals in front of them. Instead, the students will have to use all the knowledge they鈥檝e gathered here to figure out what they can do to fix what goes wrong. It could be anything from treating a sick person on the space station to correcting a mechanical malfunction.

But right now, everything is going right with the mission. The satellite has been fixed and is floating in the atmosphere again. The scientific experiments on the space station are complete, and all the batteries are working.

The Enterprise has safely re-entered Earth鈥檚 atmosphere. Upon landing, the TV screen in front of Dominico shows an animated version of the Enterprise landing on the runway. Its parachute pops open, and the shuttle slows to a stop.

鈥淓nterprise comes home,鈥� Dominico says, much as a NASA controller would. 鈥淗er flight crew is safely with her.鈥�
