Obviously, it's a joke. But I keep thinking, what if we could actually get a small propulsion device into Earth orbit? All it would need is a solar panel and a fart, and we could set it on a trajectory to collide with the moon. Even if it'd take 10 years to get there, it'd still be really cool.

There are services that launch small satellites into orbit for a fee (usually something like $30k-$60k per 1kg payload).

Why isn't this feasible?
