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.
Scientists’ ultimate goal is to have human life on Mars which can be... ... middle of paper ... ...ost of what scientists know and need to know about the conditions of Mars is know from the Skylab, Mir and the International Space Station. Photovoltaic panels will power the living units on Mars. There are limitations to this mission because of the cost budget. One problem that might occur later in the mission is how the astronauts on mars will get the necessary resources they need to survive. Because there is no way to tell if the water on mars is able to be consumed, Earth must send ample amounts of water sent to Mars (“Technical Feasibility”).
Many scientists in the past few centuries have been curious if life on Mars is possible or if it has ever been before. For this purpose, in the past century, scientists have sent several probes and experimental vehicles to the Red Planet to prove that there is a possibility of life on Mars. In the 1960s and 1970s, US Vikings and Soviet Mars probes were sent by scientists and reached Mars. Data from the Viking landers proves that there were water molecules present on the planet. The experimental vehicle, Curiosity, was sent to Mars to prove that these water molecules actually came from lakes, streams or rivers.
Jake Huffman 4/30/14 Pledged Summary on The Hunt for Life on Mars In The Hunt for Life on Mars the author, Donald Goldsmith, provides a very in depth look into the extensive search for life on the planet Mars. He gives us details of the history of exploring mars, future endeavors, and discoveries that have been made in this enormous, yet exciting task. He spends most of the book discussing a rock, ALH 84001, that is believed to be from Mars and contains evidence that has led scientists to believe that at one point there was life and could still be life hiding somewhere on the red planet. While Donald Goldsmith is not a scientist by any means, he has done considerable research on signs of life in the cosmos and has interviewed several scientists and experts while writing this book. He has also written several other scientific books on life in space and beginning of life in the cosmos.
“I don't know why you're on Mars… But whatever the reason you're on Mars is, I'm glad you're there. And I wish I was with you.” That is part of the recorded message astrophysicist Carl Sagan left to the future humans on Mars, a few months before his death in 1966. On average, Mars is approximately 140 million miles away from Earth; 250 million at its furthest point and 30 million at its shortest. If you were to take the shortest possible non-stop trip to Mars and back with our current technology, you would be in a spaceship for over a year, and one way would still take seven to eight months. What would make that journey worth it?
LCROSS stands for Lunar Crater Observation and Sensing Spacecraft. The mission was designed to search for water on the surface of the Moon. Water on the Moon has long been theorized, but previous moon missions have not found any (Lutgens 2008). The plan is to eventually have another manned mission to the Moon and to establish a base, but without water a Moon base cannot be maintained (NASA 2005). It is known that the surface of the moon that is exposed to the sun doesn’t contain water since the sun breaks it down and evaporates it as hydrogen and oxygen (NASA 2005).

Curiosity has already found ancient streams and minerals and chemicals that could support life. These are just some of the major breakthroughs Curiosity has had. Because of all the hard work that JPL scientist have put into the Mars Science Laboratory, we have been able to get a better understanding of what Mars is like and what type of life if any is able to survive on Mars.
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.
Recently, NASA has been spending billions of dollars in researching our second nearest planet, Mars. In understanding the scientific importance that such research can mean, the United States is justified in spending this money on NASA space missions to Mars. President John F. Kennedy said in 1961 that he believed that the United States could put a man on the moon before the end of the decade. Unfortunately, he never lived to see this prophetic feat performed. But in July of 1969, Neil Armstrong stepped foot on the moon before live audiences around the world.
in Begley and Rogers 58) The problem raises when it is proved that those kinds of minerals and organic molecules found in the meteorite, which fell from Mars about 13,000 years ago, can also be formed during nonbiological reactions such as very high temperatures. For us, the common magazine readers, it is difficult to deal with these two positions: the final acceptance of extraterrestrial life, which is the
