The future of space exploration will be nano-sized, but fueled by outsized ambitions. Breakthrough Starshot is a mission that may never achieve success, but it could be a boon to empowering the technology necessary to transport humans or man-made spacecraft to the stars. Billionaire Yuri Milner and famed theoretical physicist Stephen Hawking announced Tuesday the $100 million initiative to send tiny spacecraft, which could be as small as a computer chip, to the Alpha Centauri, the nearest star system, 25 trillion miles from Earth.
