Introducing NASA's New Spaceship
NASA's new spaceship is the key to making the Vision for Space
Exploration a reality. The Vision, announced by President Bush
in January 2004, will extend humanity's presence across the solar
system, starting with a return to the moon by the end of the next
decade, followed by journeys to Mars and beyond.
Building on the best of Apollo and shuttle technology, NASA's
21st century exploration system will be affordable, reliable,
versatile and safe. The centerpiece of this system is a new craft
designed to carry four astronauts to and from the moon, support
up to six crew members on future missions to Mars, and deliver
crew and cargo to the international space station.
Mockup Provides Early Glimpse of New Exploration Vehicle
As NASA's next generation spacecraft matures, engineers will document
its design with today's electronic equivalent to the blueprint.
But diagrams, three-dimensional or not, only go so far in helping
engineers understand what layouts best suit the job at hand and
the humans involved.
That's why Johnson Space Center in Houston has started building
a full-sized mockup of the new craft's cockpit in its Space Vehicle
The new spaceship -- known as the Crew Exploration Vehicle --
is the key to making NASA's Vision for Space Exploration a reality.
A quick glance at the mockup reveals the resemblance to the original
Apollo crew capsule. But the new capsule will be three times larger
and is designed to carry four astronauts to and from the Moon,
support up to six crew members on future missions to Mars and
deliver crew and supplies to the International Space Station.
Inside, the mockup remains largely unfinished. A temporary floor
foreshadows the location for launch and entry seating, and a large
hatch dominates the top of the cone. The hatch is wide enough
for a human to pass through easily and will be the point where
the crew capsule will dock with a lunar lander for the first trip
back to the Moon, currently targeted for 2018.
The mockup represents the first leg of a three-step design philosophy.
In stage one, design teams discuss various theories over how best
to utilize cockpit space and commit their ideas to paper. Then
engineers use computer design programs to produce working 3-D
models of the crew’s space. While work continues on these stages,
team members simultaneously use the mockup to experiment with
physical relationships in a real-world environment.
"You discover new things during each stage of the design process,"
said Jeff Fox, lead cockpit engineer on the spacecraft. "But your
brain needs the input of physically standing inside the real volume
of the interior space to get a true feeling of what should be
the right layout."
Workers are making changes to ensure the current model matches
the inner measurements of the most recent design. Once that's
finished, the team will start working on how to arrange seats
and where to put the spacecraft's controls.
The team is already working on plans to arrange cockpit seating
in three-, four- and six-person configurations. In the early phases,
simple foam-core boxes will serve as substitutes for real-world
hardware such as computers and cargo.
The stand-ins will gradually give way to more accurate versions
of the real thing, helping the designers visualize what the computers
can't show. As Fox puts it, "there’s just no substitute for reality."
