I am very worried about this trip to Mars there are so many dangers and problems that could kill us! I hope we can solve all or if not most of the problems we will face. I ( as Clothes Maker) will have to make very, very, warm clothing so that no one freezes.
I am worried about finding water if it is all frozen in the ground or water vapor in the air. I guess we better hope our Water Expert Habiba Chisisi knows what she's doing.
I have no idea what we can do to prevent blowing up because of the low pressure. Hopefully our Spacesuit Engineer Simon Müller can figure that out or else were doomed.
I am very nervous about the dangers on Mars but I am also excited to go to Mars. I think that together we will be able to solve the problems we face and survive on Mars.
