Lightsail propulsion could enable interstellar travel at speeds never before imagined
SMRTR summary
Researchers at Caltech have developed a miniature lightsail to study materials for potential interstellar travel. The 50-nanometer-thick silicon nitride sail allows scientists to measure laser-induced forces and movements with picometer precision, bringing us closer to realizing spacecraft propelled by light pressure.
