... . That is, it can't be too hot or too cold—it has to be just right. But outer space is a near perfect vacuum with no atmosphere or particles to maintain temperatures. This means that when ... , and in the dark can cool down to -250° F. Therefore, we need to have heaters and coolers to deal with these wild temperature swings. Other things essential to survival in space ...
... atmospheric pressure is so great that you would be crushed to death and, when it rains, it rains sulfuric acid. Mars has big dust storms, but we can survive them, just as people ...
... Mars to the moons of the outer planets will require very high velocity vehicles to be able to cover the mission distance and return to Earth within a reasonable time. These ... , but within the capabilities of known materials and physics. Human missions require that the travel time round trip be no more than several years. To accelerate the spacecraft to sufficient velocities to ...
