        Space rovers. Our key to planetary exploration. my report is about space rovers.  In this report you will read about the space rovers mission.  For example, they explored more of mars than the deep sea. Next, you will read about space rover engineering, like how the curiosity rover is as tall as the average basketball player.  Finally, you will read about Interesting facts. I’ll bet you didn’t know that we have sent at least.

The space rovers mission

        This is about the reason that we sent rovers to mars in the first place. According to Nasa’s JPL,(jet propulsion laboratory) we sent them to mars for one reason only, to find out if we are alone in the universe. With people talking of “martians”, they decided to send a rover to mars to investigate. They had to build a rover(see engineering) that could survive the climate and send information back to earth for us to study and look at.

        Here you learn about what has happened to the rovers on mars. According to Nasa’s JPL, the rover has survived many years of staying on mars and its harsh winters. Every time that winter comes on mars, the rover has to go into “hibernation”. then we have to awaken it from here in order to keep it going.

        Here you learn about results. According to Nasa, The rovers have discovered traces of water on mars. That could mean life elsewhere in the universe. Not intelligent life, but life.

 Engineering

        This is about the way that they are built. According to Nasa’s JPL(Jet propulsion laboratory), They have to make each rover different when they make them. They have better adjustments on the more modern ones. The first 2 were solar powered, but the third is not. And the more modern ones are larger. They have more advanced ways of communication and studies than the older ones.

        This is where you learn about the different advances of the rovers. According to Nasa’s JPL(jet propulsion laboratory), The first on that they sent was fairly small, whereas the 3rd one that they sent was very large, the difference in size can have their own advantages. The fist can easily be sheltered, but the third can’t. they have their different advantages.

        This is about How long they have to travel to mars. According to Nasa’s JPL, it took at least 5 months for the last one that they sent to get to mars. The others took longer, (although I’m not sure how long the others took)they take a while.  

Interesting Facts

        This is about their Space rover accomplishments. Did you know that there has been more than one rover sent to mars? According to NASA’s JPL(jet propulsion laboratory), they have several rovers sent to mars to answer the question of whether we are alone in the universe or not. They make them more advanced every time they send them to mars. The last one they sent(Curiosity) was actually the size of an average basketball player with it’s own laboratory inside, a seven foot long arm, an eye laser, a non solar powered energy supply, and so forth. It can examine things on mars and merely send us the data from mars for us to study.

 

        This is where you learn about the distance space rovers have covered on mars. Did you know that we have explored more of mars than we have the deep sea? According to, NASA’s JPL(jet propulsion laboratory) the distance that the rover travels is hard to measure. Being on rough terrain, it makes it hard to move around. The wheels may just spin in place, making the rover think that it moved forward, but it didn’t. That is why the camera that the rover has is so important. so that they can tell what the rover is doing.

        This is about the different sizes of the space rovers. According to  Nasa’s JPL, they need to increase the size each time they send a rover to mars, because they need to be able to survive the harsh martian environment. the last one that they sent, curiosity is as tall as most average basketball players, and taller than most small cars and minivans. The first rover that they sent  was nearly 3 times smaller than curiosity! That’s something you don’t hear every day! (unless you wrote this report, which you didn’t.)
