In the United States there is a program that deals with all the science and technology that has to do with space and airplanes, it is called NASA. NASA stands for the National Aeronautics and Space Administration and was founded in 1958. Since then NASA has launched many different missions to help expand our knowledge on our solar system. One of these missions was titled Galileo which soul purpose was to collect more data from Jupiter and its surrounding moons. This spacecraft was named after Galileo Galileo, the first modern astronomer.
In the 1970’s a few other spacecraft’s, such as Voyager 1 and 2 and Pioneer 10 and 11, scouted Jupiter but they were unable to stay for an extended period of time and the amount of information they brought back to Earth was limited. Scientist wanted a spacecraft that could stick around for an extended period of time and gather more detailed information about Jupiter’s environment thus the idea of Galileo was formed.
On October 18, 1986 the Space shuttle Atlantis, carrying the Galileo, was launched. Shannon Lucid was the Astronaut that performed the maneuvers that started this spacecraft on its long journey. Unfortunately, the booster rocket that got Galileo to interplanetary space did not have the power to send it right to Jupiter. However, the Engineers figured out how to borrow enough energy, using Newton’s law of gravitation, from the gravity of other planets to make it. Galileo had to take a “circuitous route that took it three times through the inner solar system, receiving gravity assists from both Venus and Earth” (McMillan 195). The path it took was nicknamed “VEEGA: Venus-Earth-Earth Gravity Assist. Galileo would slingshot once by Venus, and twice from Earth, gathering the momentum to r...

...red future plans to orbit it and possible send in a lander. The radiation Jupiter produces made it hard for Galileo to come close to the inner moon and scientist thought it would be best to save that for last. The successful flybys led to the discovery of erupting fountains of lava on Io.
The next mission was titled Galileo Millennium Mission which lasted till 2001. Europa and Io are the two main focuses of this mission but there were also studies done on the effect Jupiter’s radiation was having on the spacecraft.
Unfortunately, Galileo began to run out of the fuel it needed to fine-tune its orbit and continue to have its antenna pointed the correct way to earth. Rather than taking the risk of losing control of the space craft and having it crash into the moon Europa, contaminating it, they decided to have it crash into Jupiter’s atmosphere in September of 2003.

    The objectives of the Mariner 10 spacecraft were the foundations to influence a great scientific change in history. The primary objectives were the main reasons Mariner 10 lifted off. Measurements of environments, atmospheres, surfaces, and body characteristics were to take place (“Mariner 10” Mariner 1). Mercury’s core needed to be studied. Venus’s interaction with the solar wind and the way sun particles affected the planet needed to be explored (Howell 2). Secondary objectives included experiments being performed and the process of using the gravitational pull of one planet to reach another (“Mariner 10” Mariner 1).

  • Galileo Dbq Essay

    558 Words  | 2 Pages

    Galileo had heard about the theories that the previous scientists had stated. Galileo wanted to see if what they were saying was accurate. To prove the heliocentric theory he invented the telescope in the year 1609 that help to confirm that it was in fact the heliocentric model instead of what everyone believed which was the geocentric model. Galileo started to share his discoveries to the public, but stopped after the Church told him not to share the information. (Doc ) However, the timeline indicates that Galileo waited seventeen years before sharing the information again publicly, so he actually obeyed the Church’s request for a very long time. Galileo was a devoted Catholic and strongly believed in the words of the Bible. In a letter written in 1615 written by Galileo to the duchess of Tuscany Galileo he stated how the Bible can sometime be misunderstood,“ But [he] believe that nobody will deny that the Bible is often very complex, and may say things which are quite different from what its bare words signify…”(document A). Galileo wanted to convince the Duchess that perhaps the evidence he gathered could be used to interpret the sun’s placement as the Bible was difficult to understand at times. The fact that Galileo was so religious validated his reliability, because he would have favored the Bible over his theory. He only argued about this one concept from the Bible and he had physical evidence and support from other scientists to prove his

    Galileo’s contributions to the science of Physics and Astronomy were many. His conviction was legendary. His willingness to suffer for his beliefs exemplify true courage in the name of truth, and has inspired others to venture intellectual independence from the Church‘s creeds, edicts, and proclamations. Perhaps these contributions led to the call for an investigation into Galileo's conviction, eventually calling for its reversal, in 1979 by Pope John Paul II. But regardless of his standing in the annals of the Catholic church he will always be the man who began the separation of science and religion.

    JUNO is a NASA mission to the planet Jupiter. The Juno spacecraft is scheduled to launch aboard an Atlas V-551 rocket from Cape Canaveral, Fla., in Aug. 2011. (www.nasa.gov). It will take 5 years to reach Jupiter, arriving in July 2016. It will orbit Jupiter 33 times. The purpose of the mission is to explore Jupiter’s structure and atmosphere. The main aim of this mission is to understand how the planet Jupiter originated and thus help us understand the evolution of the gas giants. This knowledge will also reflect upon our understanding of the origins of the Universe. The spacecraft will be placed in a polar orbit to study the planet's composition, gravity field, magnetic field, and polar magnetosphere. Juno will also search to see whether the planet has a rocky core and investigate the amount of water present within the planet’s atmosphere. NASA's Jet Propulsion Laboratory in Pasadena, CA is managing the Juno mission for Dr. Scott Bolton of Southwest Research Institute in San Antonio, Texas. The spacecraft is being built by Lockheed Martin of Denver. Scientists from 5 countries ha...

    As I have described in The Lost Worlds of 2001, both projects proceeded simultaneously, with feedback in each direction. Thus I often had the strange experience of revising the manuscript after viewing rushes based upon an earlier version of the story - a stimulating but rather expensive way of writing a novel. As a result, there is a much closer parallel between book and movie than is usually the case, but there is also major differences. In the novel, the destination of the spaceship Discovery was Iapetus (or Japetus), most enigmatic of Saturn's many moons. The Saturnian system was reached via Jupiter: Discovery made a close approach to the giant planet, using its enormous gravitational field to produce a "slingshot" effect and to accelerate it along the second lap of its journey. Exactly the same maneuver was used by the Voyager space-probes in 1979, when they made the first detailed reconnaissance of the outer

  • Galileo and the History of the Catholic Church

    Galileo’s struggle with the Catholic Church is the essence of the problems people had introducing new ideas to the world. This was a time period during which people were often killed for what they believed by either the state or the church. Perhaps by not killing Galileo outright the church showed that times were starting to change, or maybe not. The episode will no doubt go down in history, however, as a turning point in science, and in religious thought.

    To speak out against the Church in this time was strictly taboo. If one spoke against the Church, it was considered heresy, which is exactly what happened to Galileo. Galileo invented the telescope and began studying the heavens above and noticed changes within the stars and planets. He observed that the "stars" that surrounded Jupiter moved. He came to the conclusion through rational thinking that Copernicus' heliocentric theory was correct.

  • Europa, The Possibility of Life

    871 Words  | 2 Pages

    In 1609, Galileo Galilei, using “spyglass” which allowed one to see things closer than they appeared, made an early version of the telescope. With it, he observed the skies in a way no one had before. He discovered the moon isn’t perfectly globular, it has craters, the Sun has sunspots, Venus orbits the Sun (contrary to widespread belief in his time), and then he observed four “stars” around Jupiter (“Our Solar System”). Within days, he realized that these objects were not stars, they were moons. Io, Ganymede, Castillo, and Europa are known as the Galilean Moons or Satellites, collectively. During the 19th century, the first measurable physical studies of these moons became achievable when Simon de Laplace derived the satellite masses from their shared gravitational perturbations and afterward, other workers used a new generation of telescopes to measure the mass of these moons. The data collected showed that the density declined from the inner to the outer satellites. According to Adam Showman, “More recent observations of water ice on the surfaces of the outer three moons led to the inference that the satellite compositions range from mostly silicate rock at Io to 60% silicate rock and 40% volatile ices (by mass) at Ganymede and Callisto” ( 77). The Voyager flybys of Jupiter in 1979 exposed indication of extensive geological activity like Europa's fractured terrains, which probably result from tidal heating and bending...

    Philae was sent into space with the purpose of investigating the surface of a comet that was orbiting the earth. It was not able to be launched from earth all the way to the comet, and therefore had to be deployed from Rosetta. One of the challenges with this is that Philae was not able to be steered, so after it was launched from Rosetta, Philae had no way of being directed specifically to the comet. Scientists had to hope that their calculations were correct, and that it was launched at the exactly right time.

    In 1609 the telescope was invented and Galileo began making his own lenses for better telescopes and then started looking at the sky. In December and January (1609-1610) it is said that he made more discoveries that changed the world that anyone has made before or since. He wrote a book called the “Starry Messenger”, and said that there were mountains on the moon, the Milky Way was made up of many stars, and there were small bodies in orbit around Jupiter. He used his mathematical skills to calculate the motions of these bodies around Jupiter. In 1610 he started looking at Saturn and discovered the rings, and the phases of Saturn (just like our moon’s phases).
