The Moon's Poles

The North and South Pole of the Moon are interesting places. Some areas near the Moon's poles are almost always in sunlight. Other places near the poles are always in dark shadows.

Earth is tilted on its axis. This tilt causes our seasons. During summer it is always light near the pole, but in the winter it is dark all the time. The Moon is hardly tilted at all, so it doesn't have seasons. Places near the Moon's poles are always on the edge between day and night.

High mountains near the Moon's poles might get sunlight almost all of the time. That would be a great place for explorers to build solar panels. The panels would make electricity almost all of the time, since they would almost always be in sunlight. There are peaks near the North Pole and near the South Pole on the Moon that are probably lit nearly all of the time.

There are also some really dark, cold places near the Moon's poles. The bottoms of some deep craters may be in dark shadows all of the time. That would make them very cold, since they wouldn't be heated by sunlight. There might even be water ice in some of those dark craters. Ice could be used by astronauts as drinking water, to make oxygen to breath, and to create rocket fuel.
