WebbThe Martian polar caps were first noted by the Italian-born French astronomer Gian Domenico Cassini about 1666. Visual observers subsequently made many key discoveries. The rotation period of the planet was discovered by Huygens in 1659 and measured by Cassini in 1666 to be 24 hours 40 minutes—in error by only 3 minutes. Webb15 dec. 2024 · The closer-in planet, Kepler-138 b, on the other hand, is confirmed to be a small Mars-mass planet, one of the smallest exoplanets known to date.

WebbMars has two permanent polar ice caps, the northern one located at Planum Boreum and the southern one at Planum Australe. Atmosphere The atmosphere of Mars is relatively thin; the atmospheric pressure on the surface varies from around 30 Pa (0.03 kPa) on Olympus Mons to over 1155 Pa (1.155 kPa) in the depths of Hellas Planitia, with a mean … Webb14 sep. 2012 · Astronomers still aren't entirely sure how the dry ice sustaining Mars' south polar cap — the only place where frozen carbon dioxide exists year-round on the planet's surface — is deposited.
Webbpolar caps are related to the Martian climate history, the seasonal polar caps are related to the current climate and circulation. By understanding the sublimation and condensation of carbon dioxide and water, seasonal change and atmospheric circulation of current and future climate of Mars will be better known. Webb25 juli 2024 · Several years into the mission, MARSIS scientists began to see small, bright echoes under the south polar ice cap—so bright that the reflection could indicate not just rock underlying the ice, but liquid water. The researchers doubted the signal was real, however, because it appeared in some orbital passes but not others.
