Voyager 1 to reach one light-day from Earth on Nov. 18
NASA says Voyager 1 will cross one light-day from Earth—about 16.1 billion miles—at 5:16 a.m. ET on Nov. 18, making it the most distant human-made object ever. The probe, launched in the 1970s, has traveled at roughly 37,763 mph since a 1980 Saturn flyby. Engineers at NASA's Jet Propulsion Laboratory recently shut down several onboard systems and activated lower-power alternatives in an effort called 'The Big Bang' to conserve its dwindling power supply.
