London Type Smog

About one hundred years ago, London, England was a dark and dirty environment. The result of this gloominess was London Type Smog. London Type Smog is a combination of smoke and fog formed when particles in coal smoke and water droplets in humid air.

What is the issue? You may ask. Back in the day, factories burned coal, and most houses were heated and used with coal. This caused the air to have soot, in which caused the air to be cold. Now, a likely reaction is burn more coal. With that, the smog got worse. This issue became worse when people's lungs filled up with the particles and gave many diseases such as, lung disease. People started having chest pain and bad coughs. By then, all the citizens of London, England knew that this had to end. Today, people in London burn much less coal. As a result, the air became more clean than it was in the early days.

Earth's Atomosphere

Earth's atmosphere is mostly made up of nitrogen and oxygen. With these gases, earth's atmosphere makes conditions on earth suitable for living things. That's why living things live on earth and not any other planet because earth provides air. Oxygen and nitrogen is very important to our universe, you can see this from the fact of oxygen and nitrogen being made up of 99% of dry air. Argon and carbon dioxide make up the other 1%. The remaining gases are called trace gases because only small amounts are present. Basically nitrogen, oxygen, carbon dioxide, water vapor, and other gases form molecules from their atoms to produce air that we need to breath!

Space Exploration

Space Exploration Summeries

The Science of Rockets:NASA uses atlas rockets to send out probes into space and satellites to orbit since 1950. Rockets are usually 58 meterstall and has 3 major stages. The first stage is the atlas which uses different kinds of engines to launch into space. The second stage is the centaur which uses liquid duel to give proper orbit. Lastly, we have the third stage called the payload which carries the satillite or spacecraft in which dissapears in space after it's released by the centaur.

The Space Program: NASA, also known as National Aeronautics Space Administration entered our world in 1958. As soon as it was built, they thought of projects within space, whether it was being able to breathe or survive in any part of space. The first spacecraftlet off was Apillo 13 which was launched April 11th, 1970, but it failed when the oxegen tank blew up.Since 1972 there has been spacecrafts traveling after knowing the couldn't use carbon dioxide. Now, they're flying to jupiter, to the moon, and back to earth!

Exploring Space Today:Instead of using a human space unit, we use an I.S.S. An I.S.S is an international space station. It includes a small robot called a personal satellite assistant. As a circular robot floats with the astronaut its solar powered cell fans allow it to move direction. Not only that, but it has sensors that tell temperature. This is a help to astronauts because it alerts when there's a problem with in space. The most helpful thing it has is a video-phone with a light to allow communication and has a mission control on earth.

Using Space Science On Earth:Less than one precent of the U.S budget goes to the space program. Everytime NASA has a venture the economy recieves $7 in return for taxes, jobs, and schools. Many technological breakthroughs have resulted from the space program in which supports many jobs. With that, it's very good for our economy!
