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.

What problems would astronaughts encounter on Mars? Create amachines/bot to solve that problem.
