NASA hopes to send a probe to Alpha Centauri in 2069

From Engadget - December 27, 2017

So why the long wait?Simple: the technology to make this trip realistic does not exist yet.The JPL is counting on propulsion technology advancing to the point where the results would come back in time to be meaningful.When Alpha Centauri is nearly 4.4 light-years away, a ship traveling at a tenth the speed of light would take 44 years to arrive.As such, it's doubtful that you or even the next couple generations of your family would live to see the results.The probe would not reach the system until around 2113, and of course the data would not get back to Earth until 4.4 years later at best.

Nonetheless, it's notable that NASA even has a mission like this on its radar, assuming budget cuts and other decisions get in the way.It's starting to think about its role in the very long term, when interstellar exploration wo not just be limited to telescopes.And if the time frame gets you down, take heart.Breakthrough Starshot is hoping to launch a small probe that would both depart much sooner and travel much faster, arriving as quickly as 20 years.Think of NASA's 2069 mission as a backup if Starshot does not work, or a follow-up that could study the star system in greater depth.
