It was November 12 when spacecraft Rosetta caught up with the comet called Churyumov-Gerasimenko better know as 67P (Lauren, 2014). The journey took 6.4 billion miles to complete (Lauren, 2014). Also Rosetta sent a lander called Philae to explore the comet and take picture among other things (Lauren, 2014). Interestingly enough when the media reported the comet landing I thing is trumped Kim kardashian attempt at breaking the internet with her nude photos which the media was cover at about the same time as the comet landing. With all that being said you might be asking why should I care? You should care about this comet because comets came from and can tell us about our solar system, also there has not been any unique and important mission as this one, further more it might be the last space mission we get to experience for a while. Now I am going to get in to what comets are and how they got here and talk a little bit

about what we hope to find on them. Like I stated above before I go in to detail about the info these comets could have I should first explain them. Comets are sometimes referred to as “dirty snow ball” and for good reason, comets are basically comprised of rock and ice (Hewitt, Suchocki, 2012). Furthermore comets are failed Jovian plant particles from when our solar system was forming from a chuck of diffuse gas called a nebula (Hewitt, Suchocki, 2012). Gas giant formed towards the out side of the nebula away from the hot center (Hewitt, Suchocki, 2012). Some of these preplant particle did not get as big as one of the Jovian plants and where take in by the massive gravity of one of the 4 gas giants but in stead of colliding or orbiting that got violently swung around and out word (Hewitt, Suchocki, 2012). Also these comets reside in one of two realms the oort cloud and the kuipler belt(Hewitt, Suchocki, 2012). So your probably wondering what dos all this mean, well it means that comets have been around since the the beginning of our solar system can you imagine what they can tell us! Now I am going to tell you about my second reason. Another way to think about comets is like untouched buried treasure that was buried from the first civilization on earth, so this treasure has been buried for billion of years and is now final surfacing can you image the stuff we can learn! Know replace civilization with solar system that is what is like to final interact with a comet so you can see this mission is very important and unique.
Studying this comets might finally unlock some of the questions we have been asking for centuries like why are we here , are we just some random accident, what is our purpose. Most members of the scientific community and some outside of it believe in evolution the ideal that we evolved from single celled organisms in the ocean; some scientists believe that this water came with the necessary nutrients and minerals for evolutionary life to begin (Lauren, 2014). Sure there have been other mission in space many in fact landing on the moon, sending robot to versus to name a few, but I don't believe that they are going to have as much of an impact as this comet mission will. These are just a few things that make this mission so unique and important because is going to help use learn more about our selves, our world and the worlds around
us! Said by Phil (2014) ”take a one dollar bill, and a pair of scissors. They’d better be sharp: Slice off a sliver just 0.7 mm wide off the end—that’s about 1/40th of an inch. That’s the total amount of NASA’s budget compared with what we spend overall”. What dos this analogy mean well that's simple, NASA is get less and less money! Overall NASA budget was 17,646 billion dollars in 2014, now the budget for 2015 is 17,460 that is a 186 million dollar reduction from the previous year. (Phil, 2014) This figures might not seem that drastic and worrisome but just wait until you hear what program have less money going to them. Probably one of the most important programs got a 56 million dollar reduction is earth science, this deals with things like global warming, and if you where in Mr.Appelhans 12/10/2014 lecture you know about the importance of globe warming and the science and the research that go’s in to it (Phil, 2014). Another large cut in money going to a program is the exploration systems development this program got cut by 300 million dollars which works on Orion crew capsules and space lunch systems (Phil, 2014). This are just two of the program that have less money going to them. With all that being said I don't know how many mission we are going to be able to do in space with NASA cutting money to so many programs! In conclusion I have show you a few things pertaining to a Space mission involving the comet know as Churyumov-Gerasimenko or 67P, And our attempt to learn as much as we can from it Also the is an drone being used for this mission and this drone sent a lander called Philae to explore and examine the comet. Next I purposed a question why should we care about this comets mission? Then I gave 3 reasons because comets came from and can tell us about our solar system, there has not been any unique and important mission as this one, further more it might be the last space mission we get to do for a while. In the first point I told you things like what a comet is, and that these comets have been around since the beginning of our solar system. Next in the second reason I stressed the importance of this mission also I mentioned that this mission could unlock some of the most important question we have been asking. Lastly In my 3 and final point I told you about how NASA budget has lost money and how some of the most important space programs are getting money cuts like earth science. 1.

"First, I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth."- John F. Kennedy. On a warm July night in 1969, this dream came true. Millions of people sat captivated in front of their TVs witnessing one of the most monumental events in history, Neil Armstrong walking gracefully on the moon. This event in US history changed the way we look at space forever. Political issues such as the Vietnam War and foreign affairs were on the forefront of American's minds. Thousands of people came peacefully together in a historical concert event called Woodstock. Children were introduced to a place called "Sesame Street" and Heavy Metal meant more than just an old car. The year 1969 impacted American's lives today in politics, science, sports, art, entertainment and daily living.
The stimulation we had to do for class focused on a piece of land in Cleveland OH that once belonged to a nuclear factory. This land consisted of 4 acres in the north-central section of Ward 12, and adjacent to ward 3. The allotment is positioned closely to many low-income segments of the South Broadway neighborhood. The goal was to come up with an idea on what should replace the decommissioned factory and create the biggest benefit for the community.

The human body is everything that makes up, well, you. The basic parts of the human body are the head, neck, torso, arms, and legs. Our bodies consist of a number of biological systems that carry out specific functions necessary for everyday living. The following paragraphs are going to explain the functions of two different body systems.
A comet is a small icy body that travels in an elliptical orbit around the sun. Halley’s Comet, or 1P/Halley, is the most well-known “periodic” comet that orbits the solar system and returns to Earth’s vicinity approximately every seventy-six years. It is one of the only comets that can be seen from Earth that is visible to the naked-eye, and can appear twice in one’s lifetime. The comet’s last visit was in the year 1986, and it is calculated to return mid-2061.

Astronomers trust that comets are leftovers of ice, rocks and gas from what shaped the planets billions of years ago. They also trust comets are strongly linked to life on earth, bringing some of the water and carbon based molecules that fuels life on soil.
A comet is a celestial object consisting of a nucleus of ice and dust and, when near the sun, a “tail” of gas and dust particles pointing away from the sun. Halley’s Comet is most famous for its seventy-five year orbital. Edmund Halley, whom the comet is named after, thought that this comet was the same comet to have appeared in 1607 and 1531. Later, discovered to be factual, Halley estimated that this comet would return in seventy-five years. Halley’s comet is most famous for returning multiple times as well as being known as

Did you know that Comets are tiny pieces of stuff left over from when our Solar System was born? Philae’s Mission is very important to scientists because, he was on a comet. Since Philae was on a comet he could collect samples and other things scientists want to understand early history of the Solar System. The Philae Mission is important for scientific research, he took a long time to get there and he landed in a bad spot.

The world survived another fairly large asteroid near Earth today, as Asteroid 1999 FN53 made its travel past our planet about 7:25 am EST. While its travel sparked some worries and concerns via Internet chatter that it could hit the Earth, NASA (www.nasa.gov) scientists weren’t concerned because they have been studying this asteroid for 16 years and knew it would not hit our planet.
For a long time, scientists have been wondering exactly what was on the surface of comets. They had not really been able to get up close to the surface of the comets and therefore gathered their information based on observations through various telescopes; that comets were just simply circular balls made of dirty looking ice. However, with the Rosetta/Philae mission, this all changed.
Everything changed on August 7, 1996, when NASA and President Clinton told the world that a very primitive life form had been found in a meteorite, from 1984. President Clinton had this to say about the matter: “This is a product of years of exploration and months of intensive study by the world’s most distinguished scientists. Like all discoveries, this one will and should continue to be reviewed, examined and scrutinized.'; After Clinton said this it was almost as if a scientific boom had occurred. NASA research teams of scientists at Johnson Space Center began to look for life as well. NASA began to send robots and Satellites to Mars. Unfortunately, they found nothing or lost contact with the robots or Satellites in the process. During the year of 1999 NASA sent up two rockets toward Mars and both were failures. Due to the failures, time has been given for scientists to blueprint a credible and step-by-step search for life on the Red Planet. Without the pressure to return Martian samples to Earth any time soon, new schemes for automated, on-the-spot detection of past or present Mars life can be flown.
First, you need to know Edmund Halley worked at NASA as an astrophysicist. Halley predicted the orbit of the comet that was later named after him. “He didn't get to see the comet return”-Space.com , but the comet had returned just as he anticipated.
