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 …show more content…
The Clementine was launched on January 25, 1994 and was on a mission to map the moon by orbiting it for two months. The Viking Landers sampled Mars' soil and atmosphere. The Mars Pathfinder also was on a mission to investigate the surface of Mars. The Galileo was sent on a mission to study Jupiter's atmosphere and all of its satellites including its moons. One of the missions of the Voyager I was to test the components of spacecraft under exposure in the atmosphere. The Voyager I was also sent to observe the moon on one of its first missions. These are just a few examples of some past missions that space probes have been sent on. Space probes are also being sent on current missions. NASA launched the Deep Space Impact spacecraft on January 12, 2005 to begin a mission to a comet names Tempe 1. The Deep Impact space probe is carrying an Impactor that is planned to crash into the comet on July 4, 2005. The purpose of this is to learn more about the materials that helped form our solar system by taking pictures of the inside of the comet. Another recent space probe is the Huygens probe. It landed on one of Saturn's moons (Titan) on January 16, 2005. Scientists are also planning future missions for space probes. These probes mean more discoveries to be made and even more possibilities added to the world of space. A very large mission that the United States is working on it building a very small, very fast probe that will pass Pluto. This is a very big deal because Pluto …show more content…
If this space probe is successful then it will only be the second probe to land on Mercury. There is also a spacecraft that still needs to be made in order to be sent on a mission to explore Neptune. All of the new discoveries and new missions that are being made call for new developments too. If scientists are going to explore further away, then they are going to need to find a way to get them there. One problem that space probes are having is the way they are navigated. Autonomous navigation is a new way to replace controlling spacecraft from the ground. This kind of controlling is being tested on the Mars Rover in the fall of this year. Another new development is ion propulsion. Ion propulsion is said to be up to ten times faster and more efficient than other types of
