URSA MAJOR - A SECRET VOYAGE TO MARS

The seven members of Ursa Major are I, Aditya, Arithra, Bishal, Kanak, Sparsha and Sudipta.

We once decided to secretly go to Mars. But we had not any spaceship to go there but this problem was solved as we found a mysterious house in a nearby forest. As we gradually build a spaceship in that secret forest, we had to solve many mathematical and theoretical problems. But could we finally reach Mars or just failed in our mission? Or was there any conspiracy behind the whole thing?
