Eubanks together with NASA isn't the only one pursuing this kind of research. Breakthrough Initiatives started its Starshot project in 2016 to combine nanometer-sized spacecraft with light sails, and in 2017, NASA began funding its own project targeted at launching a mission to Alpha Centauri by 2069, 100 years after Apollo 11. "Significantly larger probes should be possible by end century, but without unexpected breakthroughs in propulsion physics, one can think crewed missions will be a task for next century."

Small spacecraft sail are easier accelerate than larger probes, alone are not powerful or plentiful enough to push craft to near light speed. Instead, Philip Lubin, a professor of physics at University of California, Santa Barbara ideas for interstellar travel inspired Stars team, told Live Science that craft will likely rely on light instead. A momentum carried by light is transferred to spacecraft can
causes it to recoil accelerate." System is basically a gigantic flashlight — a giant laser array [on Earth]," Lubin said. If spacecraft are sailboats, then laser light is the wind in their sails.

Technology create & test such craft, such as communications equipment small enough to fit on them, is still being developed. Hope there's no physical reason to believe such spacecraft couldn't conduct a flyby mission of Alpha Centauri, Lubin said. "I!, we'll reach Alpha Centauri system, with small probes launching in near decade of 2030s, & thus arriving in nearer 2050s," Eubanks said.

Such mission behave like Voyager 1 & 2 probes. Can transmit high-resolution images of star back to Earth, some of which might contain first 3perfect look at Proxima Centauri's potentially habitable planet. Lubin stressed such journey to think, we'll reach Alpha Centauri system, with small probes launching in the decade of the 2030s, thus arriving in the 2050s," Eubanks said. Centauri would be long-term endeavor. Eubanks said he's confident a big advances could come this century.
