Imagine the power of technology hundreds of years from now. Imagine the feats we can accomplish with this technology and then the earth moon seems possible. That is, of course, if we find one there. None of these ideas could happen if this moon earth does not exist. I guess one could say that we hope this earth moon does exist because the human race might depend on it one day.
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).
As of right now, we are very limited with what technology we have. We have crude rockets and very, very inefficient rockets that use up 610 tons of liquid oxygen and 100 tons of liquid hydrogen to send a space shuttle to the moon and back. Without better technology, we can’t even hope to reach other planets within a reasonable amount of time. The closest Venus gets to Earth is 38 million km and it would take about 150 days for us to reach it. This is a relatively short amount of time if you compare it to how long it took a rover to reach mars.
This article interested me because I was shocked it took billions of years for NASA to figure out there is water on the moon. When I thought of the moon I never thought there would be water on it and it made me think about how much more there is to figure out about our universe. The field I am writing about is astronomy. In 2004 NASA launched the Messenger space craft to explore our solar system, including trip around Earth, Mercury, Venus and the Sun. It was reported this week that during its third trip past mercury, Messenger provided NASA with an almost complete view of Mercury’s surface.
If scientists and researchers had better utilized the method, then liquid-fuel rockets could have had the potential to be developed much earlier. The space race between the Soviet Union and the United States, which began during the Cold War, would be the first push towards putting humans on the moon. It was not until 1957 that the Spudnik, a manmade object was the first object to orbit the Earth. This fueled the push toward exploration of the universe and the need to put a man on the moon. The launch of Spudnik proved that putting objects into space was possible and was the first step into putting humans into space.
They’ve set up space stations orbiting the earth. They have allowed men to land on the moon, collect samples, and then return to the earth. They have sent spacecraft to explore comets and other planets. They have even sent space probes outside the known walls of this solar system. Recently, NASA has been spending billions of dollars in researching our second nearest planet, Mars.
A 1999 Gallup poll showed that 6% of Americans have doubts about the moon landing. Even though 6% of Americans doesn't sound like a lot, it translates to millions of people (Plait). It would have been easier to fake all the photographs in the Nevada desert in Area 51 than to actually perform the mission to the moon. However, NASA did indeed have the technology in the late 1960's to send men to the moon, and all the evidence they brought back proves it. On July 16, 1969 the space ship Apollo 11 left from Kennedy Space Center en route to the moon.
David McKay of NASA's Johnson Space Center says that faking a Moon rock to fool scientists around the world would be next to impossible. ?It would be far easier to just go to the Moon and get one!? he says.? (2) Moon Rocks have been tested, and tested, and tested. Each time scientists have found many different minerals in Moon Rocks that aren?t in Earth rocks.
They were given this name because early telescopes could see them only as points of light. The asteroid belt, between the orbits of Mars and Jupiter, contains tens of thousands of asteroids with diameters of a mile or more. The larger ones are spherical, but smaller ones, their cohesion greater than their gravity, are extremely irregular. There is no lower limit to asteroid size because they grade down to tiny rocks and particles of dust No asteroid is big enough to hold an atmosphere (Gardner 5). Almost all asteroids are confined to the asteroid belt, but many wander far beyond the orbit of Jupiter, and others plunge inward past the orbit of Venus.
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.
