In the United States there is a program that deals with all science and technology that has to do with space and airplanes, it's called NASA. NASA stands for National Aeronautics and Space Administration and was founded in 1958. Since then NASA has launched many different missions to help expand our knowledge about our solar system. One of these missions was called Galileo, and the purpose of the soul was to collect more data from Jupiter and the surrounding moons. This spacecraft is named after Galileo Galileo, the first modern astronomer. In the 1970s some other spacecraft, such as Voyager 1 and 2 and Pioneer 10 and 11, explored Jupiter but were unable to stay for a long period of time, and the amount of information they brought back to Earth was limited. Scientists wanted a spacecraft that could stay there for a long period of time and collect more detailed information about Jupiter's environment, so the idea of Galileo was born. On October 18, 1986, the space shuttle Atlantis was launched, carrying Galileo. Shannon Lucid was the astronaut who performed the maneuvers that began the long journey of this spacecraft. Unfortunately, the booster rocket that carried Galileo into interplanetary space did not have the power to send him directly to Jupiter. However, engineers discovered how to borrow enough energy, using Newton's law of gravitation, from the gravity of other planets to produce it. Galileo had to take a “tortuous path that took him three times through the inner solar system, receiving gravitational aid from both Venus and Earth” (McMillan 195). The path undertaken was nicknamed “VEEGA: Venus-Earth-Earth Gravity Assist”. Galileo would launch once near Venus and twice from Earth, gathering momentum for… center of paper… future plans to orbit it and possibly send a lander. The radiation produced by Jupiter made it difficult for Galileo to get close to the inner moon, and scientists thought it would be best to save it for last. Close flybys led to the discovery of lava fountains erupting on Io. The next mission was entitled Galileo Millennium Mission and lasted until 2001. Europa and Io are the two main objectives of this mission, but studies on the effects of Jupiter's radiation were also conducted. was having on the space shuttle. Unfortunately, Galileo began to run out of the fuel needed to fine-tune its orbit and continue to have its antenna pointed in the correct direction toward Earth. Rather than run the risk of losing control of the spacecraft and having it crash into the moon Europa, contaminating it, they decided to crash it into Jupiter's atmosphere in September 2003.
