In 1977 NASA Launched Voyager 1 and Voyager 2. These two spacecraft were designed to travel far into space and transmit data back to earth. Even though Voyager 1 was launched one month after Voyager 2, it over took its twin on December 19th, 1977. Traveling at roughly 38,000 MPH it became the only human satellite to exit our solar system on August 25th, 2012. It will reach our closet star, Proxima Centauri, in roughly 40,000 years. Unfortunately, the Voyagers’ power supply is dying and transmissions are expected to end in 2032.
