I had some free time today and decided to visit the National Air and Space Museum. As always, it was an amazing experience.
After examining Amelia Earhart’s Lockheed Vega and reading about Dr. Mae Jemison (she’s my favorite astronaut), I strolled to the planetarium and grabbed a ticket to a fantabulous documentary about Mars.
Did you know that Mars has the tallest volcano in the whole entire solar system? Yep, it’s called Olympus Mons and is 15 miles high (that’s like 140 Washington Monuments stacked on top of each other!)
I can’t wait until Isabel and I are astronauts so we can explore the red planet. We’ll definitely ride to the top of Olympus Mons…I’ll be sure to wave to you from outer space.
Hmmm, what else? Oh! I saw the Wright Brothers’ flyer, Apollo 11’s command module, and I even sat in the cockpit of a real jet.
Then I learned all about how planes fly. You want to know how? Well, just remember these two things: speed and air pressure.
You see, when the plane is racing down the runway, air moves under the wing faster (at a higher pressure) than the air moving above the wing (a lower pressure). And when the difference in these pressures is too much, the high pressure wins, and the wing lifts the plane off the ground. And that’s also why an airplane wing is shaped like a teardrop (round on top and flat on the bottom)…so it creates these different air pressures.
Pretty cool, huh?
Have you ever been to a museum? If so, what did you learn? I’d love to know…
