Have you ever considered life on other planets, or maybe galaxies that we have never heard of? Thanks to space probes these dreams may become a reality sooner than u think. In the past years there have been many space probes launched and even more discoveries made by them. These probes are helping people to better understand our solar system and everything it. They are also helping to make many new discoveries.
What exactly is a space probe? A space probe is an unmanned space vehicle that is designed to explore our solar system and everything in it by using very high-tech instruments. Some common instruments that you will find on a spacecraft include magnetometers, radiometers, cameras that are sensitive to infrared and ultraviolet light, and tools that can detect micrometers, cosmic rays, solar winds, and gamma rays. Space probes study structures in our solar system for various reasons. They use onboard computers to send data back to Earth. In order for these space probes to actually reach space, they must be launched with enough energy to escape the gravitational pull of the Earth. Space probes are not designed to return back to Earth.
In the past years, many space probes have been launched for many different reasons. They have visited all of the planets in our solar system besides Pluto. The earliest space probes to be launched in the United States were the Mariner Series. They investigated Mercury, Venus, and Mars. The Mariner II flew within 35,400 km of the surface of Venus. (1) It sent information back to Earth about Venus’s atmosphere, rotation period, and information on its magnetic field. Mariner 10 has been the only space probe to reach Mercury so far. Another space probe, Helios I came within
47 million km of the sun. (1) The Luna II and III space probes landed on the surface of the moon and took the first photos of the far side of the moon in 1959. Another space probe called the Pathfinder was launched on December 4, 1996 and made a successful landing on Mars in July of 1997. Other space probes to reach Mars include the Mars Pathfinder and the Mars Global Surveyor. A few other past space probes include the Voyager II, which is the only space probe to reach Uranus, The Venera VII, which was the first space probe to
