Snowfall is rare in our solar system. A tantalizing new image suggests that the dwarf planet may be one of the few places where it occurs
At 8:52 P.M. Eastern time, July 14, 2015, an all's-well signal from the New Horizons spacecraft finished its 4.5-hour, three-billion-mile trip from near Pluto through the solar system to alert mission control on Earth that it was in working order and had succeeded in gathering data ...
Even if the decade-old flyby spacecraft could have used higher frequency microwaves to return data, large improvements might not have followed
Although we've only just begun to see the scientific return from NASA's New Horizons mission and its close encounter with the Pluto–Charon system, this has been an unexpectedly profound human endeavor...
