Propulsion & Engineering
Fusion drives, solar sails, and everything that gets us moving.
Subcategories
Chemical RocketsOperational
Burn fuel and oxygen. They lift heavy things into space today.
Nuclear Thermal RocketsOperational
Heat up liquid hydrogen with a nuclear reactor. They work much faster than chemical rockets
Nuclear Pulse RocketsOperational
Push the ship with tiny atomic bombs. They could reach distant planets fast.
Fusion RocketsTheoretical
Use nuclear fusion power. They could push a ship to fast speeds for deep space trips.
Antimatter RocketsTheoretical
Mix matter and antimatter to make huge energy. They could reach a big fraction of light speed.
Bussard RamjetTheoretical
Scoop up hydrogen gas from space to use as fuel. The ship would never run out of gas.
Alcubierre Warp DriveTheoretical
Bend space around the ship. The ship stays still while space moves fast. It breaks no real rules, but needs magic matter to work.
HyperdriveFictional
Jump to a hidden space layer to skip past normal distance limits.
Improbability DriveFictional
Make impossible things happen by chance to move instantly.
Slipspace DriveFictional
Slide into another dimension to cross the galaxy in days.
Tachyon DriveFictional
Travel faster than light using special time particles.
Dark Matter DriveFictional
A dark matter drive is a hypothetical spacecraft propulsion system that harvests, reacts, or manipulates dark matter to generate thrust or warp space-time.
