Voyager 1

This year, Voyager 1 was the first man-made space craft to exit the solar system after 36 years of travelling at sixty five thousand kilometers per second!. It was launched in September 1977 and has taken photographs of the outer planets, many of which we see today. These include, the first photo of Neptune and Uranus.

Voyager 1 is equipped with a gold plate, with a phonograph, explaining the diversity of life on Earth.

This is the new topic-satellites and voyagers. Check in tomorrow for pioneer 10 and 11. Also string theory will come later on, its just really hard to get a grasp of.
