3 dni temu · Parallels of latitudes are parallel circles that run from the equator to the poles. They divide the Earth’s surface into a grid-like pattern and help us determine our distance north or south. On the other hand, meridians of longitude are lines of reference that run from the North Pole to the South Pole.
3 dni temu · For telescopic observers the most striking regular changes on Mars occur at the poles. With the onset of fall in a particular hemisphere, clouds develop over the relevant polar region, and the cap, made of frozen carbon dioxide, begins to grow. The smaller cap in the north ultimately extends to 55° latitude, the larger one in the south to 50 ...
5 dni temu · The layering is exposed around the periphery of the sediments and in valleys that spiral out from the poles. In winter the sediments are covered with carbon dioxide frost, but they are exposed in summer. At the north pole they extend southward to 80° latitude.
5 dni temu · The Mars Polar Lander was to touch down on the southern polar layered terrain, between 73 S and 76 S, less than 1000 km from the south pole, near the edge of the carbon dioxide ice cap in Mars' late southern spring.
