...engine is far more economical. With electricity generated by solar panels, it strips electrons off the atoms of vaporized mercury passing through a coffee-can-like chamber, converting them to ions. Expelled at high speeds in a focused beam, the charged particles act like a rocket exhaust, propelling the craft forward. Though its thrust is minuscule and far too feeble to lift payloads from the earth, the ion engine performs efficiently in the vacuum of space. It can function for years because it draws on solar energy and uses fuel sparingly. It can be stopped and restarted countless times...
