The solar system is filled with planets and moons. But of those worlds, few are suitable for humans. That leaves us with two closest exploration worlds: Moon and Mars. Each comes with its own unique challenges and potential rewards.
The debate over whether to send human crews to Mars or The Moon is complex, because must consider many issues like: Can it be done safely? How much will it cost, who should pay for it, and will it be worth the money? And if we decide to go, what should the goals of the mission be?
Going under a clear sky for example on Mars or the Moon is not possible without special space suits, because their atmospheric pressure is far too low for human bodies. That means humans couldn’t breathe the air, because the atmosphere doesn’t have enough oxygen. As well there is no protection for deadly radiation and a big temperature levels. On Earth we have the atmosphere and magnetic field, which protect us but out in space it bombards everything. Scientists say that a person without protection in space would lose consciousness in about nine to twelve seconds and die in about ninety seconds.
