When you travel for some hours you feel much tired. Even our machines get heated and performance quality gets degraded if we make it run for longer time. Now imagine of a machine that is doing it’s work for 30 years in the same perfect and correct condition and still has not stopped. Yes my friends, this machine is the most distant unmanned man-made spacecraft from earth, The Voyager 1. It Started its journey in Sept. 5, 1977 and now is the most distant spacecraft from earth.
