UN banned Apollo Fusion's business model of using mercury rocket propellant to launch satellites into space in c/technology@lemmy.world

Mercury would be a denser propellant than xenon/other Nobel gasses used for ion thrusters in orbit. There’s been a ton of other insane fuel types proposed over the years which thankfully haven’t been used (although a lot of rockets have and still use toxic hypergolic fuels like hydrazine)
