"The small spacecraft will be equipped with a light sail, and a phased array of lasers in the 100GW range will provide the sail with enough push to get the craft moving at roughly 20 percent the speed of light in just a matter of minutes."
That's quite impressive acceleration! The question of how they'd power phoning home wasn't explained though. But after the 20-year trip, adding a lot of redundancy to the bits of data being sent back may be one way, even if it takes a year for one picture to be sent.
This is a yah! moment, anyway. It's over 40 years since we went to the moon, so a wait of less than that to reach the stars is pretty cool. I've certainly the patience for it!
Later: Details, including communications, to be found here...
