Voyager 1 Space Detector

Voyager 1 Space Detector

The Voyager 1 is an unmanned solar space space probe developed by NASA. It weighed 815 kilograms and was launched on September 5, 1977. It will still operate normally until November 2018. It has visited Jupiter and Saturn and is the first spacecraft to provide a clear picture of its satellite high resolution. Its main mission was after the Jupiter system in 1979 and the Saturn system in 1980, ending on November 20, 1980. It is also the first detector to provide detailed photos of Jupiter, Saturn, and its satellites. The artificial satellite farthest from the Earth. On August 25, 2012, Voyager 1 became the first spacecraft to cross the solar circle and enter the interstellar medium. As of January 2, 2018, Voyager 1 is at a distance of 21.1 billion kilometers from the Sun.

The original primary goal of Voyager 1 was to detect Jupiter and Saturn and their satellites and Saturn's rings. The mission has now become to detect the solar wind and to measure the solar wind. Two Voyager 1 detectors and Voyager 2 detectors are powered by three radioisotope thermoelectric generators. These generators have greatly exceeded the initial design life and are generally considered to provide sufficient power to allow the spacecraft to continue to connect with the Earth by about 2020.

After successfully taking advantage of Jupiter's gravity, the spacecraft headed for Saturn. Voyager 1 probed Saturn in November 1980 and was closest to Saturn on November 12, within 124,000 kilometers of Saturn's highest cloud. The spacecraft detected the complex structure of the Saturn ring and observed the atmosphere on Titan. As a result of the discovery of Titan's dense atmosphere, the control personnel of the Jet Propulsion Laboratory finally decided to let Voyager 1 approach a little Titan for research, and then terminated its continued visit to the remaining two planets. As a result, the mission of visiting Uranus and Neptune was only given to the Voyager 2 detector. The decision to approach Titan made the spacecraft subject to additional gravitational forces, eventually leaving the spacecraft out of the ecliptic and ending its mission to explore the planet.

In February 2011, there were signs that the Voyager 1 probe had reached the “transition zone” at the edge of the solar system at some point before, the transition zone being the final junction of the solar system and interstellar space. The Voyager 1 Detector has reached the border, which means it will soon enter interstellar space. Once in the interstellar space, the Voyager 1 will take 40,000 years to reach the next star system. As for the battery on the Voyager 1 detector, scientists say the detector carries three nuclear batteries to ensure it continues to fly until 2025. Once the battery is exhausted, the Voyager 1 Detector will continue to move toward the center of the galaxy and will never return.

The Traveler 1 detector carries a copper disk record with an outer diameter of 12 inches, a gold-plated surface and a diamond phonograph needle. This means that even after a billion years, the sound quality of this record is still the same as the new one. Its content includes greetings and various types of music recorded in 55 human languages. In addition, there are 115 images on the disk, including pictures of the planets of the solar system, human sexual organs images and descriptions, etc. "Star Man" expresses human greetings. At the time, US President Carter’s greeting was: “This is a gift from a distant little world. It records our voice, our science, our images, our music, our thoughts and feelings. We are working hard to live our time and enter your time."
