A return to Kerbin from the surface of Minmus launcher. Emergency Kerbal return for those days you run out of Fuel. :wink:

Catapulting to orbit may not work on Kerbin but certainly on Gilly and maybe Minmus?

(Sheesh.  Now you've got me picturing it as a sort of Kerbal carnival ride.  I'm picturing all the eager kerbals lined up on the pad, waiting their turn...)

Yeah, that was the idea...

Now that we've officially been told about a few more parts, I can easily imagine pistons bringing it back into firing position. Maybe also motors (sorry, rotors), if there is a torque-speed slider. Either approach hinges (heh) on the availability of a repeatable lock/release mechanism, however...

I'm already hopeful for Minmus. If I could consistently toss a dumb payload into a long sub-orbital trajectory and pick it up with a tug from my orbiting refinery? Yes please.

Because someone has to be that guy... :P

A catapult is any apparatus designed to hurl an object with mechanical assistance. Ancient greek: kata peltes = "downward" "hurling". Unfortunately the term is often misused as a specific name for what is actually called an onager. Which to be fair is a kind of catapult. Just not the catapult.

Well I'm also that guy. :D

What about a bow and arrow?

that, is an elasticity based projectile launching system, while Catapults use inertial energy to propel things things (like a seesaw or a person throwing something),

 a bowstring uses elastic energy to propel things (like snapping someone with a rubber band)

Close! Bows store energy in the limbs. When you draw, the limbs flex, and when you loose, the limbs return to their original position. NUSensei explains it better with visuals here: https://youtu.be/A9mr66222tA?t=175

Yes, a bow stores energy in the limbs. But I'd argue that the exact mechanism is irrelevant. Catapults are generally understood to be siege engines; that is, emplaced weapons that cannot be used while someone is carrying them, and that throw large payloads. Besides that, the trebuchet is the only type that uses gravity to throw its payload. The mangonel is human powered - rather than a counterweight like a trebuchet, it has ropes for the crew to pull on. The ballista and onager are powered by torsion springs made of rope. Both a torsion spring and a bow limb (or a leaf spring for that matter) rely on elasticity and tension, they're just different shapes.
