Shuttle on top of Transporter |
We can’t go to Houston with visiting the Johnson Space
Center, where the astronauts train and the new Orion program is being run
through its testing phases. We started by touring the Enterprise shuttle fitted
atop its transporter aircraft. It was interesting to see the ideas and testing
that went into this combination including wind tunnels and then using remote
controlled models until they found a stable configuration (which required extra
weight in the front of the plane). The tram tour included a visit to the
Houston Command Center as well as one of the three remaining Saturn V rockets.
View from the Space Station |
The best part of the museum was about the International Space Station. We
learned how they worked, slept, ate and went to the bathroom as well as the
type of experiments they are running. We learned particularly about two types
of experiments – the unique things that can be done in microgravity and
experiments to help us spend more time in space. For example, Scott Kelley
spent a year in space and we learned that he lost 2% of his bone mass every
month. Osteoporosis is currently a real deterrent for long term space travel.
Other experiments are learning how to grow food in space, currently they are
looking at romaine lettuce and potatoes. They also showed how much damage that
small pieces of metal or plastic can do to large blocks of metal when they
collide at high speeds.
Orion Capsule |
The next big space program is the Orion program – the new
capsule looks 2-3 times larger than the Apollo capsule, the plan is to go to
the moon, asteroids, and eventually Mars. The trip will take 2-3 years, 6
months each way in space plus time on Mars to wait for the Earth and Mars to
align for the return trip. They are looking at various additional modules to
provide room while in space, including an inflatable module, which is
surprisingly resistant to space debris. We watched a great movie: The Journey
into Space about this future exploration, followed by a fun demonstration of
rocket science, including several interesting explosions with the warning:
“don’t try this at home”.
Apollo Capsule |
Finally, we had a quick review of past accomplishments,
which included an Apollo capsule, Gemini 2 capsule, and the Apollo 17 capsule
as well as moon rocks. They also had the lunar rover that was used for training
here on earth. An interesting factoid we learned on the tour as that the moon
has lots of Helium 3, enough that a shuttles worth of it could be used to power
the entire USA for a year! Of course, we’d have to get it here. All in all,
this had one of the best space museums I’ve been to!
