his report provides an insight into space mission 'Rosetta' which started back in 2004 with a sole aim of studying a comet. This comet commonly known as 67P/ Churyumov-Gerasimenko lies 510 million kilometers away from Earth. This report discusses the basic ideology behind the mission, followed by space probe's 10 year extraoridinary journey in space. Upon reaching the target comet, the space probe began to orbit 67P, and was all set to complete the most detailed study of a comet ever attempted. For two subsequent years, Rosetta made observations about the environment at various cometary activities and gathered data from nucleus of the comet. Some major experiments are discussed in the report. After all this data was recieved and computed, …show more content…
Its aim was to study the Comet's structure and environment in a detailed manner, along with landing a probe on the surface. It was designed to observe the comet at close range as it changes with the Sun’s heat transformations into the luminous apparition that has frightened and inspired people for centuries. This mission was developed by European Space Agency in 1993 and later received contributions from NASA. Rosetta became the first mission in history to rendezvous with a comet, orbit it and deploy a lander to its surface. Rosetta gets its name from the famous Rosetta stone that led to the deciphering of Egyptian hieroglyphics almost 200 years ago. It was named in the hope that it might unlock mysteries about water and life on Earth. 2.) Ideology Since the very beginning, comets have remained a piece of mystery to people. Many scientists today believe that comets crashed into Earth in its formative period leaving down crucial organic …show more content…
Both instruments detected lots of interesting molecules including methyl isocyanate, acetamide, acetone, and propionaldehyde, that had never been spotted even around a comet before. These amino acids enantiomers are the building blocks of life. One of the most outstanding discoveries of the mission was the detection of large amounts of free molecular oxygen gas (O2) surrounding the comet. The existence of such complex molecules in a comet, a relic of the early Solar System, imply that some parts of prebiotic material on Earth could have come from comet type celestial bodies. 8.) Conclusion Rosetta after being launched in 2004, and completing some manoeuvers reached its target position in 2014. On the course of its journey, Rosetta achieved many historic firsts in space. It completed its task to study the comet and dispatch the landing probe safely on the surface. Rosetta sent all the amazing data and images back to Earth as it kept on orbiting the comet for nearly two years. Scientists were amazed to see all the data. The mission has yielded a significant science return, collecting data from the nucleus as well its environment at various cometary activities. Molecular oxygen gas was detected around the surface and a part of the building blocks of DNA was found in the reports leading to partly prove the assumption of comet having
The spacecraft structure greatly influenced the impact of this mission on science history. The spacecraft itself weighed 503 kilograms, or 1,108 pounds. The fuel weighed twenty-nine kilograms, or sixty-four pounds. The adapter weighed thirty kilograms, or sixty-six pounds (Hamilton 1). Measuring the spacecraft diagonally resulted in 1.39 meters, or 4.56 feet. The depth measurements came out to .457 meters, or 1.5 feet (Hamilton 1). Two solar panels were strategically placed on top, both 2.7 meters, otherwise known as 8.86 feet, in perimeter measurements (Hamilton 1). This eight-sided spacecraft was also equipped wi...

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.
This comet's pattern was discovered by Edmond Halley an english astronomer in 1705 using isaacs nutions ideas of gravity . The nucleus of this comet is ellipsoidal and measures 10 by 5 by 5 miles. Halley's comet is darker than coal only reflecting 4% of the sun's rays! Halley can get from 0.57 to 35 Astronomical Units away from the sun!
Before this breakthrough no one could have thought that life occurred so amazingly early, that Earth was inhabited by a huge array of tiny life forms throughout the first four-fifths of it’s existence, and no one deduced that evolution itself evolved over geologic time. All of geological time, the total history of the earth, is divided into major eras and eons. The Precambrian eon marks the approximate age of the earth and spans a time of 4.6 billion years ago to 523 million years ago. This era is known to include approximately 90% of geologic time and covers 4 billion years of Earth history. The time period is not extremely well known or completely understood because rocks from this era are poorly exposed, many rocks have been eroded or metamorphosed, most are buried deep beneath younger rocks and fossils from this time period and are seldom found.
Rosetta Stone was a major factor in Egypt’s way of writing ancient Egyptian hieroglyphics. The stone was founded by Napoleon’s army in 1799 in the Nile delta. Britain has had the Rosetta Stone for the past 200 years. The British Museum has it as a centerpiece in their Egyptology collection. A man by the name of Zahi Hawass, who is the director of the Supreme Council of Antiquities in Cairo, has made it a point to negotiate with academics and curators at the British Museum on getting the stone back.
It among all the other montages is symbolic of the different magnifying events in the story. There is no actual rose in the story, only the word “rose” appears four times. The first two with the use as a verb. The next two occur at the very end, “A thin, acrid pall as of the tomb seemed to lie everywhere upon this room decked and furnished as for a bridal: upon the valance curtains of faded rose color, upon the rose-shaded lights, upon the dressing table, upon the delicate array of crystal and the man 's toilet things backed with tarnished silver, silver so tarnished that the monogram was obscured. (Faulkner 5.4)”

Our latest mission, SRP4, is a student designed and built payload. It will be carrying a science instrument designed by students and professors at Toyama Prefectual University in Japan. Our goal is to measure the D-region of the ionosphere.
47 million km of the sun. (1) The Luna II and III space probes landed on the surface of the moon and took the first photos of the far side of the moon in 1959. Another space probe called the Pathfinder was launched on December 4, 1996 and made a successful landing on Mars in July of 1997. Other space probes to reach Mars include the Mars Pathfinder and the Mars Global Surveyor. A few other past space probes include the Voyager II, which is the only space probe to reach Uranus, The Venera VII, which was the first space probe to
In 1958 a group known as The National Aeronautics and Space Administration (NASA) was founded. The first probe to escape Earth's gravity was the Soviet LUNA 1, launched on Jan. 2, 1959. It passed the Moon and continued into interplanetary space. The U.S. probe Pioneer 4, launched two months later, followed the same path. Later Soviet probes either hit the Moon or passed it and took photographs of the hidden far side, relaying them back to Earth.
One argument that supports the panspermia theory is the emergence of life soon after the heavy bombardment period of earth, between 4 and 3.8 billion years ago. During this period, researchers believe the Earth endured an extended and very powerful series of meteor showers. However, the earliest evidence for life on Earth suggests it was present some 3.83 billi...
Space has always been a pivotal and utmost important subject for many years. In the past, scientists have made monumental advances in this field such as sending people into orbit and landing a man on the moon. Of course, this has only barely been explored and we still have a lot more to see of the ever-vast outer space. One of the most significant topics of all of science has only been touched and there’s still more to come.
The labyrinth is one of the most important aspects to the portrayal of knowledge in The Name of the Rose. Its design and purpose are a brilliant metaphor to the churches desire to keep knowledge from the poor and powerless. The story of the labyrinth goes right back to a Greek myth, which tells of a beast with the head of a bovine and the body of a man, who was conceived of a woman and a snow white bull. It was confined to a labyrinth from which there was no escape without assistance. The concept that Eco uses in The Name of the Rose is very similar, except instead of guarding the Minotaur, Eco’s labyrinth guard’s books, the knowledge that could be the destruction of the church’s vice-like grip upon society. The minotaur wanted seven young maidens and seven youths per year to quench it’s appetite, and one year the Greek hero Theseus became sick of the killing and offered himself as a sacrifice to the bull, with the intention of killing it. He went in with a ball of string and a sword, the ball of string he used to trace his path back to the start when he had killed the Minotaur. There are distinct parallels between William, and the hero Theseus. William entered the library with the intention of getting at the contents that it was protecting from society, which of course were the books, just as Theseus entered the Minotaur’s labyrinth to rescue the young men and w...
