This is a sling. Bottom right corner is a catapult and uses stored energy (the elastic - sorry if wrong wording.) To me at least the idea of a sling that pivots around the user’s hand is much closer to the action of using a planet’s gravitational pull to sling a satellite craft onwards.
Good point! A satellite is more likely to orbit a planet monitoring things I guess? It’s been a while since I’ve played Kerbal Space Program.
