MISSION TO MARS

Is it possible for humans to survive on Mars? With concerns over globa warming and over population on the rise, NASA and other scientists fromaround the world have begun to explore this question with increased vigorHowever, relocating to Mars is not a simple task and a great deal of informationmust be gathered before we can even consider it as a possibility. During thenext three weeks, you are going to help mankind take a giant step in thisinformation gathering process by construction a rover that has a wide array ofremote sensing capabilities and sending it to the red planet to collect data.

Assignment 1--ENTRY, DESCENT, LANDINGThe decent to the red planet is treacherous. In this assignment you will design anbuild a rover that can survive this hazardous journey.

Assignment 2--CONTROLLING YOUR ROVERFor this assignment you will program a rover that has the ability to autonomouslynavigate through the harsh Martian environment.

Assignment 3--MAPPING MARS

Assignment three will require you to map Marss surface.

Assignment 4--LOOKING FOR WATERDuring this assignment, you will use your rovers light sensor to analyze Marssgeological make-up.

Assignment 5--RETRIEVING SAMPLESIn this final assignment, you will program your rover to collect soil samples andreturn them to base.

Please use this graph to answer the following questions.

1. What does the X-axis represent?___________________________________________

2. What does the Y-axis represent?___________________________________________

3. What happens when you turn the wheel quickly?

_________________________________________________

_________________________________________________

4. What happens when you turn the wheel slowly?

_________________________________________________

_________________________________________________

5. What happens when you do not turn the wheel?

_________________________________________________

_________________________________________________

6. Look back at the story that we started this lesson with and try to create a graph that shows therovers motion. Once you are done, print the graph and staple it to this page. How does thisgraph compare to the one that you created at the beginning of the lesson?

0.To look at your data, click on the that is to the left of your programming pallet.

1.Once you are in the new screen, place your rover in front of the IR tower and press the to upload youdata. Your data should look something like this.

2.Now it is time for some algebra. If you remember, 1 rotation = 16. What equation do we have to use to makrotation = 1?

3. After you figure this out, select the icon. The screen that opens will have a calculator at the bottomhat looks like this. Enter your equation into this calculator and watch to see how the graph at the top of th

creen changes.

This equation says the value of the blue bucket (the value of my rotation sensor) multiplied by 10 equals thevalue of the green bucket.

14.How can you change the next function and constant to make this into equation tell you the distance that trover traveled? Think about the discussion we had after assignment two. Write your equation here and then

type it into RoboLab.

15. Use your graph to figure out how far your rover traveled.

LOOKING FOR WATERBackground: Sedimentary

Rocks--Sedimentary rocks are

ormed at the surface of the

Earth, either in water or on

and. They are layeredaccumulations of sediments:

ragments of rocks, minerals,

or animal or plant material.

Temperatures and pressures

are low at the Earth's surface,

and sedimentary rocks show

his fact by their appearance

and the minerals they contain.

Most sedimentary rocks

become cemented together

by minerals and chemicals or

are held together by electrical

attraction; some, however,

e m a i n l o o s e a n d

nconsolidated. The layers are

normally parallel or nearly

parallel to the Earth's surface; if

hey are at high angles to the

urface or are twisted or

broken, some kind of Earth

movement has occurred sincehe rock was formed.

Sedimentary rocks are

orming around us all the time.

Sand and gravel on beaches

or in river bars look like the

andstone and conglomerate

hey will become. Compacted

and dried mud flats harden

nto shale. Scuba divers who

have seen mud and shells

ettling on the floors ofagoons find it easy to

nderstand how sedimentary

ocks form.
