Caltech scientists are developing laser-driven lightsails that could push spacecraft beyond our solar system. Their research ...

"The lightsail will travel faster than any previous spacecraft, with potential to eventually open interstellar distances to direct spacecraft exploration." Scientists at the California Institute ...

A team of researchers at the California Institute of Technology devised a means of measuring the thin membranes of a lightsail, helping prove out a futuristic travel concept first imagined by ...

"The goal then would be to see if we can use these nanostructured surfaces to, for example, impart a restoring force or torque to a lightsail," says Gao. "If a lightsail were to move or rotate out of ...
