    Getting situated.

    Okay, first stop. Lower Earth orbit.

    Before heading out any further, we need to get you situated with our starting point – Earth. Our little blue marble of life. For many of you, this will seem like your very first trip to space. But in reality, you’ve been rocketing through space all your lives. Because, realize it or not, we’re all living on a rock moving roughly 100,000 kilometers per hour through our solar system. And in that sense, Earth already is a kind of spaceship.

    Now, looking at Earth from space, I’m going to ask that everyone tilt their heads just slightly to the right. That’s it. It’s only now that you’re actually looking at our planet head-on. This is because as Earth orbits the sun, it’s perpetually tilted at an angle of 23.5°. As we orbit the sun once a year, Earth keeps a constant tilt, maintaining the exact same orientation for the entire journey.

    Alright, now look toward the edges of Earth. See that creeping shadow? Well as you might have guessed, that’s the night beginning for those parts of Earth. But, what you might not realize, unless you’re looking at Earth head-on, is that it’s always exactly 50 percent covered in sunlight and exactly 50 percent in darkness. Forget daylight saving time, long winters, summer solstices, that’s just where you happen to be located on this tilt. People in Antarctica can see daylight for 24 hours in December . . . but Earth as a whole? Without exception, it’s always 50/50.

    And it’s this very tilt that dictates everything we know about the sky. From the stars we see, to the path of the sun. Many people believe that high noon means the sun is directly overhead. But, in fact, if you’re looking from the US, you’ll never, at no point of day or year, experience the sun directly over your head. It just doesn’t happen. Because in the US, you’re always witnessing the sun at an angle. This also means you’ll never see all the same star constellations that the Southern Hemisphere does, and vice versa.

    So, if you can all untilt your necks . . . now we’re situated and looking straight ahead. It’s time to start our tour through space at our solar system’s crown jewel – the sun.
