note- There are 4 endings- Success, Failure and 2 hidden endings. Hint for hidden ending 1 If your falling velocity goes below 0, ie in negative, the rocket is going upwards. You have to figure out the escape velocity on mars, and divide it by 100, then go that many meters per second in negative speed. Hint for hidden ending 2 In the quote write the name of the largest country, that doesn't exist today.
