the art of throwing humans away from Earth so violently they fall around it forever
means Astronautics is the science and engineering of designing, building, and navigating spacecraft to travel beyond Earth's atmosphere.
from From the Greek astron, "star," plus nautes, "sailor" — literally a "star-sailor's" craft. It's modeled on the older aeronautics ("air-sailing"), itself built from the same nautes that gives us nautical and astronaut. The word arrived in the 20th century as rocketry turned the old dream of sailing among the stars into a working profession.
