  • Voyager 1 is a space probe that was launched by NASA on September 5, 1977.
  • Real-time distance and velocity data are provided by NASA and JPL.
  • At a distance of 152.2 AU (22.8 billion km; 14.1 billion mi) from Earth as of January 12, 2020, it is the most distant human-made object from Earth.
  • Voyager 1 is the first human-made object to venture into interstellar space.
  • Voyager 1 discovered a thin ring around Jupiter and two new Jovian moons: Thebe and Metis.
  • At Saturn, Voyager 1 found five new moons and a new ring called the G-ring.
  • Voyager 1 and Voyager 2 are still functioning today, making them the longest-running and most-distant space mission in history.
  • Though they are each taking different paths, both spacecraft are still screaming their way out of the solar system.

•  INSAT- The Indian National Satellite (INSAT) system is one of the largest domestic communication satellite systems in the Asia-Pacific region with nine operational communication satellites placed in Geo-stationary orbit.
• Sputnik-  Sputnik 1 was the world’s first artificial satellite.  It was the Soviet Union’s first successful satellite.
