Nasa Jet Propulsion Laboratory : A Launch Mass Of 54 Kgs Essay

Have you ever wondered what it would be like to fly in space or work on the crew at NASA that helps the astronauts get home safely? These two jobs both use many of the laws of physics. In fact, almost everything they do involves physics. Apollo 13 is a movie that epitomizes what those jobs are like and how much physics is required. The three main laws of physics in the movie were Newton’s Law of Universal Gravitation, Newton’s First Law, and Newton’s Third Law.

The law of conservation of mass states that matter can be changed from one form into another, mixtures can be separated or made, and or substances can be decomposed, but the total amount of mass remains constant. Taking this law from a different view we can state that the total mass of the universe remains constant. Whenever matter undergoes change the total mass of the products will be the same as the total mass of the reactants. For example, in this experiment sodium hydroxide and copper sulfate, the reactants have a total mass of 21.4 grams. The total mass of the products, copper hydroxide and sodium sulfate, was 21.13 grams. The 0.27 grams was a result of the solution staying on the thermometer that was used to measure the temperature. This law was formulated in the end of the 18th Century. It marked the beginning of modern history.

The rapidly increasing amount of carbon dioxide may be one of the factors that cause climate change. As Hillman states, “Concentrations of carbon dioxide in the atmosphere are increasing, and have done so since the Industrial Revolution.” An atmospheric CO2 concentration, research shows that there is a dramatic increase from 280 parts per million (ppm) in 1750 to 373 ppm in 2002, a rise of the third. Furthermore, the linear chart demonstrated the trend of annual global CO2

Underneath the largest rocket in the world, on May 8, starting at 11:00, were sixth graders. The entire sixth grade of South Mckeel Academy slept underneath the Saturn V rocket. Not an experience to forget. Previously, the middle schoolers had taken a brief tour of the Kennedy Space Center Visitor Complex, which houses the space shuttle Atlantis. They would actually get to visit the shops and kiosks on Friday, the day after. Onto the subject of the rocket itself.

The second artwork I chose to evaluate is Romare Bearden's Rocket to the Moon. This collage uses black and white as well as color. Bearden used warm colors throughout the collage and unified everything very nicely. Throughout this artwork a square pattern is visible making everything well balanced. You can see the pattern on the windows, bricks on the walls, and the actual buildings themselves. There is some implied motion also visible in the small rocket at the very top of this collage. It is as if the rocket is taking off to the moon on the upper right hand side. The moon implies that this scene possibly takes place at night but, it seems to be a very well lit day. A lot seems to be going on in this scene but, the focal point are the people

Should we be funding exploration of the depths of space when our very own planet hasn't been explored to the fullest? Should we being inhabiting the solar system and potentially harming it knowing how poorly we've taken care of Earth? "We are the only earthly creatures with the capacity to extend our influence beyond the 4 corners of the globe." so what should we do with this power? (Source E) Funds and ethics should be big factors when considering space exploration, but they're not big enough.

In March of 1926, Dr. Robert Goddar successfully launch the first modern rocket propelled by liquid fuel (First liquid-fueled rocket). Before this time Rockets were launch using either gun powder of steam to propel their rockets, but what Dr. Robert Goddar was more than just launch a simple rocket, but open up new possibilities and a look at the future. Before this time rockets were used in wars by the Chinese as they were attached to arrows and/or spheres to strike their enemy (Rockets in Ancient Times). Over time Rockets have changed greatly, from essentially being a sphere and not being able to get off the ground to becoming fuel propelled machines that can take us billions of miles into space.

Along with the technological advances and new theories of the last century, humans have developed a need to explore beyond the known of the final frontier. This resource of knowledge has led to superstitions and concerns about what could happen if people pursue this want of space exploration. Among these concerns are national finances, the world’s health, and ethical standpoints of what really could be waiting on the other side for those who dare venture into the unknown.

Horizontal analysis is when an individual looks at the income statement of a company and compares one year to the other to see what kind of percentage it has increased or decreased within the different departments in a company for any given time period. When looking at Competition Bikes (CB) and performing a horizontal analysis, we would take a look at first year 6 and year 7. Between year 6 and 7 there was an increased net sales of 33.3%. This means that from year 6 to year 7 there was a great increase. This means that the customers were happy with the product being sold, and this is a sign of strength within the company. It was a profitable year.

The study shows that any release of carbon dioxide is happening in a very gradual manner that is taking far longer than originally was thought would occur, which is good news for the Earth’s environment.

“Live and learn”: a classic saying that applies to everyone and everything. Sometimes people mess up on small things but, other times one flaw could lead to a huge mistake that people must learn from. NASA’s Challenger was no exception to this saying. Many lives were lost on the space shuttle including a teacher from Concord. However, this tragedy holds a story worth being told.

This year I got over my fear of horses. For my fifteenth birthday my aunt got me four weeks of horseback riding lessons. My lesson horses name was Skyjet. At first I was terrified of the horse and how big it was, but really it was one of the smallest ones there. I learned how to groom the horse on put all the gear on it. I learned how to 5-star which is when you go into a squat forward leaning position and stay like that, I learned how to post which is kind of like doing squats but instead of going down you are going up, also how to get the horse to trot and stop. To trot you say trot on kick the horse's side until it does. To stop you pull the reigns to you and release when they stop.

Formal: Zhang Huan became famous for using his own body as his medium. His works focus heavily on his body's ability to endure massive discomfort in order to bring his artistic concepts to life. 65 Kilograms portrays Huan being hung horizontally against the ceiling with an attached IV hanging down towards a hot plate on the ground. The name represents exactly how much Huan weighed at the time of the exhibition. As Huan hung in the air, blood dripped out of the IV onto the hotplate. As the show proceeded, 65 Kilograms became a heavier and heavier visceral experience for those in the audience. The cruelty that Huan subjected himself to was not only a visual display, but a highly olfactory one as well. Huan's blood and sweat both slowly frothed

The Space Shuttle was an interesting exhibit with many fascinating attractions. There were a lot of connections between how the spaceship works and our class, electricity and magnetism. One of the main connections between these two were the tires on the space shuttle. The spaceship only used one set of tires per trip because it needed to have a lot of traction in order to stop the ship in time which means that they can not be reused. Throughout the trip however, the tires go through a lot of change. Once they escape the Earth’s atmosphere, they lose a lot of pressure. The air inside the tires could go through a phase change that would cause energy be created which in return energy is calculated by Q=mLf.

• Carbon dioxide (CO2) is a greenhouse gas that warms the atmosphere. • Since pre-industrial times, atmospheric CO2 concentrations have increased from about 280 parts per million (ppm) to over 380 ppm. Current concentrations of CO2 and other greenhouse gases are unprecedented in at least the last 650,000 years, based on records from gas bubbles trapped in polar ice. • Independent measurements demonstrate that the increased CO2 in the atmosphere comes
