"The Starshot concept capable of making the journey to the Alpha Centauri star system 4.37 light-years away. It envisions launching a "mothership" carrying about a thousand tiny spacecraft (on the scale of centimeters) to a high-altitude Earth orbit for deployment. A phased array of ground-based lasers would then focus a light beam on the crafts' sails to accelerate them one by one to the target speed. At a speed between 15% and 20% of the speed of light, it would take between twenty and thirty years to complete the journey, and approximately four years for a return message from the starship to Earth."
- cmrdporcupine 5y agohow does it slow itself down for entry into the alpha centauri system? seems like it would just blow past it
- dvirsky 5y agoIt doesn't. It snaps some pics, sends them back and moves on.
- codethief 5y agoActually, the Wikipedia page for the project notes in one of the subsections: > The travel times are for the spacecraft to travel to the star and then enter orbit around the star (using photon pressure in maneuvers similar to aerobraking). Not sure how trustworthy that information is but this kind of "aerobraking" at least seems possible in principle.
