Near-relativistic swarm could image Proxima b at 20-meter resolution and scan for biosignatures, paper says
Laser sail propulsion is an idea that won't go away. By aiming powerful Earth-based lasers at tiny spacecraft with light sails, tiny spacecraft can be accelerated to near-relativistic speeds without carrying fuel or an energy source, and without carrying any kind of propulsion system at all. There a...
