Kirigami-enabled solar sails let sailcraft turn without propellant

A University of Pennsylvania preprint by Gulzhan Aldan and Igor Bargatin describes using kirigami — patterned structural cuts — to generate steering torques for solar sails, enabling turn maneuvers without propellant. The technique addresses a long-standing control limitation for propellant-free sailcraft.

Inside NASA's Campaign to Detect and Neutralize Tens of Thousands of Hazardous Asteroids NASA says our Solar System contains tens of thousands of potentially dangerous asteroids that could annihilate a city or worse. A dedicated NASA office is leading planetary‑defense efforts to detect, track and, when necessary, neutralize Earth‑bound threats before they can strike.
