when the full—size one is built, it will take a small satellite, stick it inside a giant dart, load it on to a 100m—long arm, gradually spin it round and round, faster and faster and then, let it go at 5000 miles an hour. don't believe me? i don't blame you! this idea sounds completely nuts. well, you know what's nuts is rockets. rockets are combustion chambers that burn cryogenic propellants at temperatures that are greater than, like, the surface of the sun. they have thousands of components that are made out of the most exotic materials known to man and are on the verge of blowing apart at any possible minute. i think spinlaunch is quite a bit less nuts than a rocket. and, look, as the day's gone on, i've started to believe it.
