1/15 Scale Space Shuttle Stack Apollo EMU


1/15 Scale Space Shuttle Stack


Apollo EMU


The Space Shuttle is designed for economical and routine access to space. The Space Transportation System includes the manned orbiter, External Tank (to fuel the Orbiter’s main engines during launch); and two Solid Rocket Boosters, which provide additional thrust during the early launch phase. The entire System, except for the External Tank, is reusable.

Display dimensions: 69" x 17’ tall


Astronauts who walked on the Moon during the Apollo program (1969-1972) wore multi-layered suits designed for comfort, utility, and protection from the harsh environment of space. Special outer gloves, boots, and helmet were also needed.  A life support backpack was worn to provide cooling, oxygen, and communications for the suited astronaut.

Space Shuttle Flight Computer

The guidance, navigation, and control system is composed of the four orbiter computers and other major components which make up the primary flight control system. The computers use a program called the digital autopilot to control the vehicle through launch, ascent, on-orbit, deorbit, entry, and landing. The guidance, navigation, and control system provides automatic or manual (control stick steering) control of the vehicle in all flight phases. During launch most of the computer commands are directed to gimbal the main engines and solid rocket boosters. To circularize the orbit, in orbit, and for deorbit, the computer directs the orbital maneuvering system. At external tank separation, in orbit, and during a portion of entry, vehicle attitude control commands are directed to the reaction control system. In atmospheric flight the computers direct the orbiter aerodynamic flight control surfaces.

Salyut panel

This is but just one of the many panels that were on-board the Soviet Salyut-6 space station - a precursor to MIR and the ISS space stations.  One report states that it looks more like a sequencer initiator, rather than a computational device, which would call up canned control programs for various mission phases.  We are not certain what function this panel was used for aboard Salyut-6.  If you can help us understand this panel, please send me e-mail at mapld2003@klabs.org.

Coming soon - a replica of Goddard's rocket built by the NASA Marshall Space Flight Center.

March 17."The first flight with a rocket using liquid propellants was made yesterday at Aunt Effie's farm in Auburn. . . .It looked almost magical as it rose, without any appreciably greater noise or flame, as if it said, "I've been here long enough; I think I'll be going somewhere else, if you don't mind." . . .Some of the surprising things were the absence of smoke, the lack of very loud roar, and the smallness of the flame."

From Dr. Goddard's Diary

 

Coming soon - a model of the original Wright Flyer, custom built for MAPLD!
