Solar Sail Propulsion
A method of spacecraft propulsion using radiation pressure from sunlight on large mirrored surfaces. Like a sailboat using wind, solar sails harness photon momentum for fuel-free interplanetary travel, enabling missions to distant destinations.

How similarity is calculated
Each concept is converted into a 768-dimensional vector using the nomic-embed-text
model. Similarity scores are calculated using cosine similarity—measuring the angle between vectors.
A score of 100% means identical meaning; lower scores indicate decreasing semantic relatedness.
