What is Pioneer 10?

Pioneer 10 is an unmanned spacecraft, the first ever to exceed the asteroid belt and studied Jupiter and its months. Pioneer 10, which was launched on 2 March 1972, is also the first probe to reach the solar system. At present, the orange gigant star Aldebaran, which is the "eye" of the bull, forms the constellation Taurus, located about 65 light -years away. If our ALDEBARAN system and the system had zero speed with each other, the Pioneer 10 would reach it in about two million years. Walking through the asteroid belt was not difficult - although it is sometimes portrayed as dense with asteroids, they are actually very spread. The first real pioneers of the external survey of the solar system believe in their name, Pioneer 10 and its sister craft, Pioneer 12. solar wind parameters; Cosmic rays; The transitional area of ​​the heliosphere; Neutralhydrogen abundance; distribution, size, mass, flow and speed of dust particles; Jovian Aurorae; Jovian Radio Waves; And observing Jupiter's atmosphere, as well as its satellites.

Pioneer 10 craft was 276 kg - small for interplanetary probe - and was built as part of the Pioneer program from the NASA Ames Research Center. Like some other vessels designed to leave the solar system, it included an informative plaque sent as a message to all extraterrestrials who could pick it up in the future.

More recently, Pioneer 10 observed that it was very slightly accelerated towards the solar system as it still moves out. This was called a pioneering anomaly. This slowdown does not prevent Pioneer 10 from leaving the solar system, but its presence is very confusing to physicists who are accustomed to predicting the physical behavior of such objects. Although the reason for thisColoring can be secular, such as gas leakage, and all new physics is also considered.
