Future propulsion

Light-speed and semi-light-speed concepts.

Near-light-speed travel is a frontier physics and energy problem, not a near-term product. AeroVectrix presents it as speculative research literacy.

Photon Sails

Laser-pushed sails can theoretically reach very high fractions of light speed for tiny probes, with enormous beam and pointing challenges.

Fusion Rockets

Fusion propulsion could raise exhaust velocity, but controlled compact fusion propulsion remains undeployed.

Antimatter

Extreme energy density, but production, storage, safety, and cost are far beyond practical propulsion use.
