TRAVEL IN SPACE
1. Explain the problems associated with landing people on Mars including (a) large distances, (b) food and water (c) shelter, (d) oxygen supplies, (e) what to take, (f) other costs, (g) other problems
The problems associated with landing people on Mars is that, for starters, the fact that Mars is almost 79 million kilometers from Earth, it would take almost six months just to reach Mars. If we were to colonize Mars then the trips would have to be planned very carefully, and extra caution would be needed to be taken to make sure that nothing is left behind, it would no use arriving on Mars to discover that you have forgotten a very important piece of equipment. The large distances also means that you would have to be precise about the amount of fuel to be taken, and extra fuel would also need to be considered in case the space shuttle looses some along the way.
Food and Water would also be a big problem with travelling to Mars. As stated before, the six months it takes to get to Mars would also mean that the food and water, especially the water, would need to be made sure that there is enough of it to last long enough before the next lot of supplies can reach them. If it were possible to grow fruit and vegetables on Mars that would also help, and if it were possible to melt some of the ice fossils on Mars then water would not be a problem, but with the unpredictable sand storms on Mars it would be difficult at the start to grow the food that humans need to survive.
The temperatures on Mars can reach as low as -140 C during the Winter time and -85 C...
