Voyager 1 is a space probe launched by NASA on September 5, 1977. Part of the Voyager program to study the outer Solar System, Voyager 1 launched 16 days after its twin, Voyager 2. Having operated for 39 years, 9 months and 9 days as of today (June 14, 2017), the spacecraft still communicates with the Deep Space Network to receive routine commands and return data. At a distance of 138 AU (2.06×1010 km) from the Sun as of March 2017, it is the farthest spacecraft from Earth as well as the farthest man-
The probe's primary mission objectives included flybys of Jupiter, Saturn, and Saturn's large moon, Titan. While the spacecraft's course could have been altered to include a Pluto encounter by forgoing the Titan flyby, exploration of the moon, which was known to have a substantial atmosphere, took priority. It studied the weather, magnetic fields, and rings of the two planets and was the first probe to provide detailed images of their moons.
After completing its primary mission with the flyby of Saturn on November 20, 1980, Voyager 1 began an extended mission to explore the regions and boundaries of the outer heliosphere. On August 25, 2012, Voyager 1 crossed the heliopause to become the first spacecraft to enter interstellar space and study the interstellar medium. Voyager 1's extended mission is expected to continue until around 2025, when its radioisotope thermoelectric generators will no longer supply enough electric power to operate any of its scientific instruments.

If you have visited Stevenage Town Centre you may have noticed this sculpture. To find out what it is, does and why it is there Jerry Stone has arranged with Stevenage Town Centre Management for us to go along and let the public (and us) know its purpose.
Why not come along and wave the flag for the club?
