Evacuation systems have been built into launch pads since
the 1960's Saturn rockets took astronauts to the moon. Earlier systems
consisted of a cable
basket that would take evacuated astronauts to the ground.
The re-engineered Launch Complex 39B will need to handle the
new Orion
spacecraft and its Ares 1 rocket. For quick evac,
NASA turned to the world's roller
coaster designers for help.
In the event of an emergency, astronauts will jump into tram
cars and head face down toward the ground (see illustration) from a height of
approximately 370 feet.
"Technology
developed for the public thrill-seekers is very applicable here," says
Scott Horowitz, head of NASA's effort to return to the moon.
Once completed in 2012, the NASA 'coaster will be the
world's third tallest, after the Kingda Ka at Six
Flags Great Adventure in Jackson, New Jersey, and the Top Thrill Dragster at
Cedar Point in Sandusky, Ohio.
Attention NASA engineers: check out the RoboCoaster G2 - Extreme Robot Roller Coaster for ideas
for extra thrills on the way down. People who don't meet NASA's height requirement (not to mention being an astronaut) can still enjoy the Shuttle Launch Experience at the Kennedy Space Center.
