 * Search for Life on Mars (SLM) – Wiki Entry 1 **

Electricity is a form of energy that is common used in household objects to power them.There are three types of energy static, current, and discharge. Each has it's unique  set of qualities and uses in real world situations.Static electricity is caused when atoms atoms are ripped from one object and added to another causingan imbalance of atoms in to objects.A example of static electricity is when you rub a balloon on your head and it stick Current electricity is electricity that flow of electricity a circuit. A example of static electricity is when energy flows through a light bulb and makes it light up.The last form of electricity is discharge it is the rapid flow of electricity from one place to anther.A example of electric discharge is the plasma inside of the plasma ball.

The way that we could use electricity on mars is by using current electricity power a rocket so the astronauts can stay alive. After that we can use to to mechanically move it on to mars. we could use static electricity to test the soil to see if it is positive or negative. Then we can use current to control the rover and go very in depth about look for life. Then use discharge to blast off and head back to earth.

_ __ Search for Life on Mars (SLM) – Wiki Entry 2 __ __  Magnetism is when atoms line up in the same order so the attract other objects of the same. One example of how magnetism is in your computer multiple  magnetic metals are used in your computer so if you put a magnet near your computer the atoms line up erasing the code that is put in them by programming. Another example is bullet trains they use magnetism to levitate it above the tracks so it moves really fast. The last example is a compass it works by using magnetic that always point towards the  north pole to tell directions. __



__**There are many uses of magnetism on mars. One use of magnetism on mars are using it for landing by placing electromagnets on the objects so the object will be attracted to mars by magnetism.you could also use it to attract rocks and dirt on mars to examine them.You can also use it to power the rover without using batteries.**__

Search for Life on Mars (SLM) – Wiki Entry 3 All the matter and energy in the universe was in some way created by the big bang. The most important items where all created in seconds or milliseconds. When everything began the temperature was very high to the point where atoms could not be formed. As the universe began to cool down matter and antimatter began to collide to make energy luckily there was a little more after then anti mater so objects could be created. The universes temperature gradually began to drop so when it dropped to 3000 degrees kelvin atoms where created. Three billion years since the beginning of the universe galaxy began to form. After that collisions where common among galaxy.

Most of the Milky Way is made of gas stars and dust. The milky way is also a spiral galaxy and the solar system is locater on and outer ring.in the middle there is a ball with gas and many stars closely jam-packed together most likely in the center of that is a black hole.

A star is formed when another star explodes. A star is made up of interstellar gas and a core of hot gas. A star turn’s hydrogen into helium to create energy .Everything about star is preset by its mass. All stars eventually expand and explode to make a super nova.

The sun is a star made up of hot gas .There is a cloud of gas formed around the sun that can only be seen during solar eclipses. The sun will use up to 4 million tons of hydrogen of hydrogen in its life time the sun also shots jets of gas. That gas can be shot past our solar system

After the sun was formed a disk around the sun collected many planetoids. Most ones closer to the sun where made of rock and metal and the ones farther away is made of ice rock and metal.in the beginning the planetoids collide and ether break apart or combine to create larger planetoids that went on to create planets. All the smaller planetoids went into space or joined the asteroid ring. They also went on to form moons.

NASA __ In 1957 the Soviet Union launched a satellite in though space. Once Sputnik was launched the government was hurrying to create a new branch of the government devoted to exploration of space. The branch was NASA. This new branch played a very important role in the space race against the Soviet Union. It was also important because it was in the middle the cold war and people where talking about the possibility of launching missiles from space so you could keep our country safe and able the lunch missiles that could be potentially undetectable. In December of 1957 we launched our satellite. __

__ As the years have gone on the important of NASA in space exploration and discover has increased dramatically. We even launched Hubble into space to capture and explore space. As the world has develope d we have become more extravagant by launch many robots to mars the newest one the size of a SUV. Overall one of NASA greatest an achievement is having the first man on the moon which was only a few years after it was founded. __

Rocket Experiment Summary

At first it would not launch we the rocket then the ignition was switched out and then it launched. It flew up strai t. It flew up to 100 meters in the sky. Then the parachute launched. Then the rocket started to fly towards the left. The rocket went towards a building and went missing. I believe painting the rocket was important it made it so it was power full enough to fly high but not powerful enough to fly all the away to the C but I think it could have been a little heavier so it would not fly away so easily. I believe the purpose of the experiment was to help us learn how rockets launch into space. As we going further into this unit the use of rockets is very important in putting people an mars because that is how the travel there. It helped figured out how a basic rocket works. The experiment was preformed in a very logical order. Before launching we painted them so they weighed more First the rocket was placed on the lunch pad and the guiding pole. After that the clips where placed on the rocket to send electricity to it. The rocket was launched and then it was chased after and picked up. After launching we used trigonometry (100* tan of the angle) to figure out the height of the rockets. My groups rocket went up to 100 meters in the air.

Mars Rover Drop __The design of our drop vehicle had one thing in mind everything we could use to brace the impact use it. We had 2 cup joined with a rubber band inside of that we had a base layer of paper towels and then a layer of bubble wrap. On the outside we had a layer of bubble wrap. Then we had a bag to place that in with two balloons another layer if bubble wrap you place around it. The cushioning worked well but the throwing technique could be improved along with making it more air resistance to slow it down. There could still be more cushioning. I think we should add a parachute and another layer of bubble wrap. __



_ <span style="display: block; font-family: Arial,sans-serif; font-size: 16pt; text-align: center;">A Brief History of Robots __<span style="font-family: Arial,sans-serif; font-size: 12pt;">The first robots made in 270 B.C. where water clocks and organs made by Ctesibus an ancient Greek engineer. As time went on people started to think up new ideas of robot like Leonardo da Vinci who imagined a human like robot. There were also many writers that imagined robots mostly in a bad light. For example “Rossum's Universal Robots" by Karel Capek that was about man made robots that robots turned around and killed the humans. In 1942 “ The Three Laws of Robotics “ were written by Asimov. __



__<span style="font-family: Arial,sans-serif; font-size: 12pt;"> As the years went on robots became more industrialized along with the industrial revolution starting with the development of the conveyer belt to be produced. After the industrial revolution we continued to advance General motors gets the first programmable robot arm that they use for production. In 1964 one of the first computers is produced sold by IBM. Carnegie University develops a eight leg robot in 1994 and it successfully goes on mission. In 1998 launches a learning system for robotics. Today robots are even being used for exploring mars or helping here on earth. Roots are helping humans go to places they have never been to from the depths of the ocean to space. __

Programming Robots <span style="font-family: Arial,sans-serif; font-size: 12pt;">Motors can be programmed many <span style="font-family: Arial,sans-serif; font-size: 12pt; line-height: 1.5;"> different ways. The way we input the programs into the computer of the robot was directly wiring it in. You can put many different ways including driving it forward, reversing it, driving in a square, making it take point turns and curve turns. With all of that you build upon each other them to create custom programs to beat challenges. But along with that there are some troubles with the robot. Sometimes if you id not get the programming just right the robot would do something different than you thought it would. Also even when you did the programming right the robot would turn at a diagonal.

<span style="font-family: Arial,sans-serif; font-size: 12pt;">After you do basic program you move into sensors they are like your senses but for robots. The senses help the robot detect things. There are many types of sensor for example the sound sensor which listen for sound and make the robot do something when it hears a sound. Then there is a touch sensor that makes to robot stop when it touche <span style="font-family: Arial,sans-serif; font-size: 12pt; line-height: 1.5;">s something. After that there is the ultra-sonic sensor it emits sounds that the human ear cannot hear and see if they bounce back at it and when it detects an object it turns or stops. Lastly there is the light sensor it senses when colors change so it stops or turns.

SLM – Wiki Entry 9: Geology on Mars

<span style="font-family: Arial,sans-serif; font-size: 14pt;">Geologist use different experiments to conclude what different minerals make up a rock. One of the tests they use is using light refraction which is seeing what happens when the rock is put over text. Another test is UV light this is used because only certain rocks refract UV light. The way they do UV light testing is by taking a black light and shining it onto a rock and see if the rock shines a different color. One of the big tests is just observing color texture and shine then they check that against the characteristic of other minerals and try to find a mineral that has the same characteristics. The last way is by using chemical testing by putting acid or other chemicals on the rock or mineral and see if reacts and a certain way. These are just the tip of the iceberg in testing minerals and rocks.



<span style="font-family: Arial,sans-serif; font-size: 12pt;">The big reason for testing the geology on mars is to test for life forms. Many other rovers have traveled to mars but they were not as intricate as curiosity. It has tools on the outside collect rocks and minerals. On the outside it also has a a camera or geologist to make observations. Inside of the rover it has a laboratory to test the rocks and minerals. It sends the data from that back to earth so we can decipher different things about the geology of mars.
