Laser-Propelled Nano-Space Probe to Reach Alpha Centauri in 20 Years?
“Breakthrough Starshot” intends to
squeeze all the key components of a robotic probe—cameras, sensors,
maneuvering thrusters and communications equipment—into tiny gram-scale
“nanocraft.” These would be small enough to boost to enormous speeds
using 100-gigawatt
laser pulses, which would rapidly push a nanocraft to relativistic speeds.
