The Smithsonian’s National Air
and Space Museum is working
on a new gallery in its
Washington, D.C., facility that
will include a raised stage for
public programming, a large
interactive touchscreen where
visitors can help design a virtual
space station, a large projection
of the Earth’s limb, or circular
outer edge, and more.

The Airbus A320 simulator re-creates National Airport takeoffs and landings.

Below the large room, expected
to open around the end of the
year, will be a complete television
production studio and control
room to serve a wide range of
missions. It will have a two-way
fiber connection to the NASA
headquarters television control
room just a few blocks away for
live media exchange.
The new gallery, “Moving
Beyond Earth,” will include a
globe-shaped screen from Global
Imagination that will be illuminated
from within to look like Earth
and other heavenly objects. Four
other projectors will show the
Earth’s limb along the top of one
of the room’s walls. The round
stage, complete with speakers and
footlights, will also have five video
cameras that can drop down on
telescopic mounts, for potential
applications like distance learning
and multi-site events. One wall will
feature a fly-around tour of the
International Space Station.

Museum videos are now powered by Flash servers.

The room will also feature 15
small interfaces for quizzes. And
in testing now is a large tablemounted
multi-touchscreen.
When finished, it will allow visitors
to help design a space station;
they can build on the work
of other visitors’ earlier in the
day, and at the end the museum
will e-mail participants a graphic
of the completed station design.
Another special interactive
installation, tentatively entitled
“You Are The Flight Director,” will
let visitors speak with others via simulated video teleconference
to help solve a space-related problem.
The new gallery is just the latest improvement
at the museum. In 2008, it installed an Airbus
A320 simulator that used four screens and six
computers to re-enact takeoffs and landings at
Washington Reagan National Airport in Virginia.
(A museum worker rode the route in a helicopter,
holding a camcorder out the window to capture
the original video data for the project.) The simulator
also provides audio, including authentic
cockpit and air control chatter.
FLASH SERVERS SURE BEAT
A ROOMFUL OF VCRS
It wasn’t that long ago that the 85 or 90 screens in the
Smithsonian’s National Air and Space Museum got their video
from regular old (pro-grade) VCRs. Running all day everyday, the
machines populated a room in the museum and ate through
read/write heads by the case.
Now, said Bob Curran, the museum AV supervisor, most of
the displays have Flash memory media servers, right on the
unit, secured in some cases by two-sided tape. Not only is the
museum saving on VCR repair, but the networked boxes let
curators schedule and quickly change programming. Adtec
Technology and Alcorn-McBride units are used on large-format
monitors and projection systems where HD video is required.
The Adtecs are capable of 1080i video, but the museum found
720p actually looks better on the Sharp 65-inch monitors.
For smaller screens, the museum uses MediaWhiz players,
smaller and with fewer features than the Adtecs. It’s also checking
out other makes.
And the 100 or so interactive computer screens are lightyears
away from their sources-or up to 900 feet, anyway. Using
gear from Magenta to strengthen the signals for the long ride,
the museum moves the touchscreen signals back to the computer
in the basement and sends the video up; users at the
screens notice no latency, as if the computer were right there.
