Comet Essay

Apollo 13 was to be the third mission sent from the Apollo Project to land on the Moon. An explosion in one of the oxygen tanks caused the spacecraft to become crippled during the flight and the crew were forced to orbit the Moon and return to the Earth without landing. The Apollo 13 mission was launched on Saturday afternoon, April 11, 1970 from launch complex 39A at Kennedy Space Center. The space prime crew consisted of trained experts Commander James A. Lovell Jr., Command module pilot Ken Mattingly and Lunar module pilot Fred W. Haise Jr. There was also three backup crew members named John W. Young, John L. Swigert Jr. and Charles M. Duke. This crew was ready to step in if for any reason something were to happen to any of the main

The Perfect Storm by Sebastian Junger is an account of an immense storm and its destructive path through the North Atlantic. In late October of 1991, crews of several different fishing ships left their port for their final haul. Little did they know that they would soon cross paths with one of the greatest storms ever recorded. This particular storm would create huge swells, high winds, and hard rain. The system, was said to be a “perfect storm” because all of the elements were just right to create the worst imaginable storm ever seen, “… a hundred-year event,” claimed some meteorologists. These types of storms are caused when: “Warm air is less dense than cool air; it rises off the surface of the ocean, cools in the upper atmosphere, and

Homer Hickam was a teenage boy from a mining town in West Virginia called Coalwood. He inspired to build rockets when he seen the first artificial satellite, Sputnik, streak across the stars. With his friends and the local nerd, Homer sets out to do just that but with many errors and trials. Along with the town, Homer's father thought they were wasting their time with their rockets. He wanted Homer to be a coal miner just like everyone else but Homer knew he didn't belong there. As time went on, some people from town became interested in seeing the homemade missiles launch into the sky. The boys became popular and were known as the "Rocketboys" around town.

Apollo 13 launched on April 11, 1970 from the Kennedy Space Center in Florida. The crewmembers aboard the ship were James A. Lovell Jr., John L. Swigert Jr., and Fred W. Haise, Jr. Before the launch, there had been a few problems. Thomas K. Mattingly was supposed to fly on the Apollo 13 but he was exposed to the measles. He didn’t have the antibodies to fight the disease, causing him to not be able to go into space. Swigert took his place. Right before the launch, one of the technicians saw that the helium tank had a higher pressure than expected. Nothing was done to fix this. During liftoff, the second-stage engine shut down, causing the other engines to run longer than planned. Apollo 13 was off to a rocky start.

The Apollo 13 mission was a significant historical event, because of the dangerous repercussions that followed the explosion of the oxygen tank on Apollo 13. The story in which the astronauts Lovell, Swigert, and Haise surviving these errors during the flight is truly incredible. In the movie Apollo 13, the creators depicted most of the events involving the crew’s adventure to and from space quite accurately. Although creating most events successfully the creators of Apollo 13 failed in many regards when it came to the creation of the plans the crew used to survive, and the small details that were missed, involving the crew in the process of flying the space shuttle and surviving the accident.

But they don’t quite know what else that a comet is made of. The mission Philae that was launched could lead them to those answers. “ The Philae lander will travel the surface of 67P and conduct a variety of scientific experiments. It could reveal secrets about the makeup of comets, the formation of our solar system, and even origins of life.” this mission could be the most helpful mission to help people know about comets. Just looking at the pictures could answer many questions, including what comets are made out of.

In the book “A Magnificent Catastrophe” the author, Edward J. Larson, writes about all of the little details that has occurred in the First Presidential Campaign in the 1800s. He begins his book with how the two parties, the Republicans (Jefferson) and Federalists (Adams), were going to compete in who will govern the United States now that it is a free country and no longer under Britain’s rule. Although they had at first been friends they soon became enemies because of how they believed the government should be. Jefferson believed that the government should be a populist government that trusted popular rule. While Adams believed that America should have a strong government and that al

1) How would you convey the message of the book “Half the Sky” to family, friends, and colleagues?

Stardust collected the particles without destroying them for the analyzation of interstellar dust for data and information to study for NASA. Most of the particles that Stardust collected from the comet are smaller that human hair. More than 1000 particles were collected and complete for analysis by scientists. This encounter took place in space, 242 million miles from earth. On Jan 19, 2006 the capsule with samples was separated from the spacecraft and successfully returned to Earth. The capsule was recovered by a chase aircraft in the Utah desert by NASA team of scientist. They concluded and found interstellar dust particles within the Stardust capsule in 2006, ten years ago. The team consisted of 200 international scientist employed by NASA. The comet's location is in the outer solar system within Kuiper Belt beyond Pluto. This comet was new to its orbit and still has most of its dust particles and gases. However the mission was successful and completed on Jan 15, 2006 with the return of the capsule. The Stardust mission samples indicated that some comets may have included materials ejected from the early sun and may have formed very differently than scientists had theorized. Scientists that studied samples of Comet Wild 2 and found that the minerals formed under extremely high temperatures meaning close to the sun and not in the freezing cold at the Solar System's edge, where most short lived comets come from. "In the coldest part of the solar system we've found samples that formed at extremely high temperatures," said Donald Brownlee, during a press conference. "When these minerals formed they were either red hot or white hot grains, and yet they were collected in a comet, the Siberia of the Solar System." Stardust ceased operations in March

     A tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes can produce massive destruction with wind speeds of 250 miles per hour or more. The typical tornado moves from southwest to northeast, but they have been known to move in any direction. The average forward speed of a tornado is 30 miles per hour but it may vary from stationary to 70 miles per hour. Although tornadoes occur in many parts of the world, they are found most frequently in the United States east of the Rocky Mountains during the spring and summer months. In an average year, 800 tornadoes are reported nationwide, resulting in 80 deaths and over 1,500 injuries.

1.I’d first have to say that the head of mission control on the ground was definitely

NASA contributed to a number of successes in American history. During the past, the organization has rapidly acquired a number changes that has created an opportunity to expand and improve Knowledge Management (KM). Similar to many other important organizations, NASA has frequently pursued ways to capture knowledge into their information systems assuming that it could be managed best when it 's captured in a system for later retrieval. In the past 10 years, the budgets on their missions have been reduced, missions have multiplied ten-fold, and scientists and engineers have been overwhelmed by the extreme challenges. The most important factors that are addressed includes the importance of learning, (FBC) faster, better, cheaper implications, and knowledge management that supports innovation in the future.

Due to the large number of space exploration projects, a large belt of debris has formed that can be hazardous to other operational spacecraft. As engineers, we have an ethical responsibility to prevent pollution of Earth’s atmosphere. We have learned a hard lesson on the value of environment from right here on Earth. Trends show that the debris belt circling the Earth will only get bigger, and become more hazardous to spacecraft.

A tornado is defined as a violently rotating column extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of two hundred and fifty miles per hour or more. Damage paths can be more than one mile wide and fifty miles long. In an average year, eight hundred tornadoes are reported nationwide, resulting in eighty deaths and over one thousand five hundred injuries. In the body of my essay, I will tell you about types of tornadoes, where tornadoes come from, where and when tornadoes occur, the damage they inflict, variations of tornadoes, and how to detect tornadoes.

The word Meteora means in Greek, "suspended in air" and, of course, refers to the saints monasteries erected here secular orthodoxy. What created this unique cluster of rocks remains a mystery of nature, and this despite the advanced theories of scientists, unproven theories until today. But the more spectacular is the landscape offered by nature man Meteora with art as he joined his art, creating one of the most beautiful places not only in Greece but worldwide.
