Why We Can Reach Pluto But Can’t Fly Above the Sun

What is actually above the Solar System, and why is flying straight up from the planetary plane harder than reaching Pluto? This space documentary explores orbital mechanics, delta-v, gravity assists, the ecliptic plane, the heliosphere, heliopause, Oort Cloud, Scholz’s Star, Local Interstellar Cloud, Local Bubble, ancient supernova explosions, iron-60 on Earth, the Sagittarius Stream, Fermi Bubbles, the Milky Way’s dark matter halo, and the true structure of our cosmic neighborhood. We also examine NASA and ESA missions including Voyager 2, Ulysses, and Solar Orbiter, explain why humanity still has no real top-down photograph of the entire Solar System, and reveal why there is no universal “up” in space. This video is for viewers interested in astronomy, astrophysics, space exploration, NASA missions, the Milky Way, the Solar System, and scientifically accurate explanations of how the Universe really works.
