he Search for Life on Mars

From the Big Bang to Galaxies
The leading theory in the creation of our universe is the big bang. A event in which the earth the size of a atom expanded in a flash and formed into what it Is today. The big band also caused the solar system to form. The galaxy that we live in could either be a spiral, elliptical, and irregular. We don't know which one because we have never ventured out of our own galaxy before. The earth formed into hydrogen molecules which made the shape of it.
The History of The Solar System
The sun formed from interstellar gas and condensed to a little disc but then got bigger because clumps of solid material and became the sun. all of the planets were also made by discs being made that pulled in solid objects. The moon was most likely made by a collision between earth and a small planet which broke up the object that hit the earth and formed the moon. A giant meteor collided into the earth and made most living things on earth die.
The Milky Way Galaxy
The milky way has a disc going around with stars and dust particles in it. In the center of the disc is a bulge type figure which has stars, dust, and maybe planets we do not know because we haven't ventured that far because the bulge is about 25,000 light years away from the sun. The galaxy is very big but it may be bigger then we think because of the bulge in the center of the disc. We think if we go to the disc we will find about 5 times the size of this galaxy which is tremendously huge but we still have to venture there.


Wiki Entry 2
The first rocket is unknown but people think the Chinese accidently made one by making explosions and instead of them exploding it launched into the air. Then they started using these in wars and fights and it eventually became a rocket propelled arrow. The wars were won easily by the Chinese when they discovered this. Then in 1898 a Russian school teacher proposed to do space exploration using a rocket. In the early 20th century Robert H. Goddard conducted experiments with rockets. In 1915 he began using different type of fuels to see which would go farther. Then rockets were born and have since then been used for space exploration.

Wiki Entry 4
The rocket adventures of this century are mostly robot adventures. The most recent adventure is curiosity which is in orbit right now. The robot is going to be in mars by next summer. All of theses robots have one thing in common which is mars.
The exploration of mars are very interesting, considering all of the work that goes into it. The work that does into it is especially complicate with all wires and transmitters. The landing is one of the hardest parts of the mission because you have to have airbags impact the ground and have to individually detonate the airbags.
The mission take over 1 year to perform and 5 years of preparation. The preparation is the big [art because no human or earth particles can contact it. The missions are very crucial part of space exploration. The explorations are very important in nasa.

Launch day

The launch went great besides the parachute not ejecting right and two fins breaking after it landed on its side. The rocket did launch fairly high it was the second highest launch in the class. The launch went great the liftoff and the flight it just didn't eject the rocket. Then since it didn't eject the rocket the fins broke when it impacted the ground.

The purpose of the experiment was to see if mass effects how high the rocket travels. The mass was all the same for every rocket until we painted them because the amount of paint you put on the rocket the more mass there is going to be. The experiment was performed by launching 10 rockets all with difference masses and then see which one goes highest.

Rocket fin experiment
The purpose of the experiment was to see if the amount of fins or where the fins are placed change the altitude of the rocket. The rocket were affected by the changes a lot. Instead of the rocket with the most fins going the highest the rocket with the 2nd least amount of fin went the highest. The winning rocket only had 3 fins which was the second least. Amount of fins. The rocket that traveled the highest had angled fins at a 90 degree angle. This design is used in super sonic rockets which go faster then the speed of sound. The rocket unfortunately didn’t exceed the speed of sound :(.
Our rocket weighed 48.5 grams. It went 23.1 meters in 0.5 seconds then soon started turning and spinning. The launch wasn’t successful as the first launch most likely because of added 3 fins onto it which caused more mass then it spiraled out of control.



Robot History

The first robot was made by archytas a very smart Greek mathmetation the robot was a pigeon powered by steam which was not only the first test of any flight but most likely the first model airplane. Then in 1495 Leonardo Davinci invented the "Leonardo robot" which in medieval years they would make inventions to make the king laugh. Jacques De Vaucanson invented 3 robots the first one was a robot that could play the flute. The second robot played the flute, drum, and tambourine. The most famous invention was a invention that was a duck that moved quacked and flapped his wings like a real duck he called this moving anatomy.
Charles Babbage demonstrated a prototype of his different engine designs in front of the royal astronomical society. He continues to do his work by designing even more ambitious project. Nikola tesla also demonstrated a remote controlled boat at Madison square garden in 1898. Fritz Lang's movie Metropolis is released. Maria the female robot in the film is the first robot to be projected on the silver screen. Issac Asimov produces a series of short stories about robots starting with A Strange Playfellow later renamed Robbie for Super Science Stories magazine. The story is about a robot and its affection for a child that it is bound to protect. Over the next 10 years he produces more stories about robots that are eventually recompiled into the volume I, Robot in 1950. then in 2004 the first mars rover lands on mars and is succesful as the first ever mars mission.

Robot programs

in ORDER FOR A LEGO mindstorms robot to move you need motors. these motors move at the same right going forward and backwards. they only go at different speeds when turning because when turning one wheel spins while the other doesn't. If the right motor moves then it turns left and if the left motor moves it goes right. The curved turn involves the wheels still moving but not stopping. the wheels still spin but one goes slower then the other and causes it to curve on like the pivot turn in which one wheel stops. the program software that comes with it programs the motors to do all of these action thoroughly and simply.

Geologists identify minerals and rocks by using rock hammer and eye lens. The eye lens help when examine rocks to figure out what type of rocks or minerals they are. Geologist hike to locations where there are a lot of rocks.
The mars rover curiosity is NASA's most recent rover that is going to explore mars. The rover has a full collection of geology tools. The rover has a laser, a drill. The drill is to collect materials that are going to be tested by nasa. The laser is for getting an idea of what type of material it could be if it is out of reach.

There are 8 characteristics of life. They are that you have to be made up of cells, need materials, homeostatic, respond to stimuli, reproduce, grow, adapted to environment, respiration. The characteristics all have to happen to be living. So the living thing has to do all of those things in its life time in some point in their life. The characteristics do not have to be in any order they just have to be completed.

How can life be detected on other planets? Well life can be detected in many sorts of ways but the way you do it with a robot would just sample soil and if the robot has a microscope it would use that. The number one way to know if life exists on the planet is if you find water in the soil or if you find a type of area that is lower then others that might have been where water was. The water method that N.A.S.A.uses is just follow the water if you find any then you will find life even though that works 30% of the time it is not a good method.
