You're up, then you're down. In space, though, things are different. But it falls around, not down.
Planets fall around stars, moons fall around planets.
They keep going forever, yet they do not repeat themselves. As soon as there are more than two things falling around each other, gravity becomes complicated, new paths endlessly become available. Johannes Kepler, who put rules to the planets' movements in the 17th century, imagined them humming a ceaselessly shifting melody, the music of the spheres. So in space, falling is a science, inscribed in Kepler's laws and Isaac Newton's equations. It's also a practical skill.
