NASA's dream house.

Get a load of the latest plnas for space station Freedom--the high-tech trailer home that will somebody house four astronauts for long-term stays in space. Could you see yourself living and working here? Or could you alter design to make your space habitat even more habitable?

LIVING WHERE? Freedom will be about the length of a football field. But astronauts will spend most of their time in the living and laboratory moduels (1) attached to the station's aluminum backbone(2).

BREATHE DEEP Astronauts aboard Freedom will breathe an Earthlike combination of nitrogen and oxygen. Tanks containing extra stores of these elements in liquid form (3) will be tapped when needed.

SUN POWER Solar panels that rotate to catch the Sun's rays (4) will generate enough electricity to keep everything form lights and microwave ovens to computers and communication systems running smoothly.

IT'S TOO DARN HOT When the temperature rises abroad Freedom, you can't just open a window. Instead, a cooling system similar to the one that keeps your fridge cold carriers heat out of the modules and radiates it into space (5).

HELPING HAND What happens if something on the space station breaks down? The crew will send a robotic ar, (6) to do the repair work. The arm can travel the length of the backbone, and even "walk" off its track to reach trouble spots.

LOST IN SPACE Over time, Earth's gravity will try to pull Freedom out of orbit. But fuel-powered rockets (7) will periodically give the station a boost to push it back in line. Should some life threatening emergency arise, the crew can always abandon ship in an escape capsule (8).

SPACE HABITAT This module (A) will be the center of the world for Freedom's crew. Here they'll eat, sleep, bathe, exercise, go to the bathroom, work on the computer--everything except conduct experiments. There will be three separate lab modules for that.

MADE IN THE U.S.A. . . .and Japan, and Canada, and Europe. Freedom is not exclusively American. Scientists from all over the world are cooperating to make the project a reality. This laboratory module. (B), for example, will be built by the Japanese.

FRESH SUPPLIES! This "logistics" module (C) will be the storage area for food, equipment, and other supplies. To resupply the space station, shuttle astronauts will remove this moddule and replace it with a and replace it with a fully stocked one.

THE GREAT OUTDOORS To get the true meaning of space science, you might want to mount an experiment on this "exposed facility" (D). A small robatic arm will help you set things up. What would you study in the total vacuum of space?
