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

This page includes the generated electric-spacecraft image for advanced propulsion and future research topics.
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.
