Stranded on Mars question?

Suppose you were on a spaceship that landed on Mars, but during the landing the main guidance computer system broke down on the space ship. What does this mean for you and your crew? Well there is limited food available, limited oxygen - just enough to last for 2 weeks. But there is NO POSSIBILITY of a rescue mission being sent to get you.
Now, although the guidance system is out, all of the resources to repair it are around you. You even have another computer with internet connection that works. It is just a matter of using your creativity to rig up a solution that will fix the guidance system and enable you and your crew to take off and head for home.
The bottom line is that unless you fix the guidance system computer, you will die on Mars.
How would you fix the guidance system, given that there are no scientists in the crew?
Would you find an adventure like this exciting or would you be afraid to volunteer for such a mission?

Why is there so much order around?

Well its not somethin new, but still it has not been resolved for me. after the no. of answers i got for the light n gravity part im quite sure that we have quite a intelligent ppl around. So the question goes like this...in the quantum world i.e on the microscopic level everything is described by probabilities and in a sense is very chaotic. But when we see the macroscopic world everythin is so orderly and predictable keepig in mind the fact that their fundamentals are just a set of probabilities.....>>>? i dont get it as to how things get more orderly when they reach the macroscopic scale!! anybody?

Will Zero Point Energy EVER be available to the general public?

Or will the powers that be lose too much of their power if they relinquished their hold on us through the sale of energy?

Before you comment that ZPE is fiction, I suggest you check your source. Not only is it feasible, it is in use today. I have witnessed it with my own senses.
