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.
Taryn Harris #10567 and Claire Werner #10230 Mr. C Science 8, Period 6 21 April 2014 The Wonders of Space Rocks In our solar system, there are a vast variety of space rocks. Space contains comets, asteroids, and meteors that rush through space, but don’t make it to Earth because they burn up along the way. This is due to the amount of friction that is produced on its journey through space. Comets, asteroids, and meteors are only a few objects that orbit through space and in our solar system. As a result, these various space rocks fly throughout our solar system, creating a bunch of chemistry.
But in July of 1969, Neil Armstrong stepped foot on the moon before live audiences around the world. As he stepped out on this extraterrestrial surface, he stated the now famous words, “That was one small step for man, one giant leap for mankind.” But why was Kennedy so adamant about sending men to the moon? What significance could such a feat serve in our lives? Of course, we lived in a different time then. Many believed our effort to send a man to the moon was just an attempt to display the philosophical superiority of capitalism over communism during the height of the Cold War.
In 2013 a team of astronomers discovered a new planet eleven times more massive than Jupiter and 650 astronomical units from it’s star. It’s relatively new, only 13 million years old, and still glows from leftover heat from it’s formation. This planet defies many of the limitations scientists know about star and planet formation. It’s too far away from it’s star to have been formed by gathering asteroid-like bodies from the creation of the star or to be made of dust and gas clouds in the primordial disk. Astronomers also considered the idea that it might be a failed start formed during binary star formation however the mass ratio of the planet and it’s star is too different for that to be likely either.
Early astronomers and Greek Philosophers believed that the Earth was the center of the universe, and that gravity was thought to pull all things to the center of the universe. Finally, the heavens were perfect places, they were unchanging, perfect spheres. This ended up to be proven incorrect by Astronomers such as Copernicus, Kepler, and Tycho and their challenges of the Earth or geocentric model. Travel to the moon would have been impossible much earlier than the first landing of the moon in 1969. This is because the first telescope was not even invented until 1609 by Hans Lippershey, and the moon was first observed by telescope in 1610 by Galileo.
This topic probably will not affect our generation, or the next few, but it is something that should be in the corner of our minds so it won't be much of a shock when it does happen that we send humans up to the Moon to live. "Mankind is drawn to the heavens for the same reason we were once drawn to unknown lands and across the open sea (Bush internet)." Life on the moon would be an expansion to human intelligence. It would literally broaden our horizons.
Nevertheless, even with positive extrapolation of robotic manufacturing techniques, Mars will not have the labor required to make it fully self-sufficient; until and unless its population is in millions. Thus it will be necessary for colonization of Mars to import goods from Earth. Benefits There are many prospects
According to a report sponsored by NASA in 1992, "The Spaceguard Survey: Report of the NASA International Near-Earth Object Detection Workshop", the hazards from asteroids can be divided into three broad categories that depend on the size and/or kinetic energy of the impactor (Bar... ... middle of paper ... ...ements and assess impact probabilities (Anonymous I 1) In the end. asteroids will be either our nemesis, causing problems we have never faced before or they will be our saviors in space. They will provide us with resources to carry on throughout the solar system end beyond. Bibliography: Anonymous, Blast It! (Mavbe Not).
Looking through his telescope Lowell became convinced he could see a network of artificial canals. This led him to believe that there were intelligent beings on Mars who had built these canals. However, spacecraft have now visited Mars and found that there is no evidence of water at all. It is now thought that the lines he could see were the combination of Lowell's overactive imagination, and scratches on the lens of his telescope. We are now searching one of Jupiter's moons, Europa, as this seems to be the next likely place to hold life.
Life on Mars and Jupiter's Moon Europa As the future proceeds and life begins getting more technical, Earth may not be the only place where the human race resides. There is already talk that some day Mars will be inhabited by humans. Jupiters moon Europa may be the next after that. Two space missions have already studied Mars. The Pathfinder, which landed on the surface of Mars was one of the missions, and the Global Surveyor, which is a satellite, is the other mission.
