Jul 27, 2018 · Although few traditions about Mars survive, astronomers focusing on Australia have evidence that Aboriginal peoples across the region tracked it and the other planets carefully for millennia. And ...
Nov 28, 2023 · Astrobiology is the study of the origin, evolution, and distribution of life in the Universe, and searching for life on Mars is a major goal of the Mars 2020 mission. While humans have long wondered whether there are others like us, it’s only been a few decades since we’ve developed the technologies to search for life beyond Earth in earnest.
Jun 12, 2012 · In this review paper I address the current knowledge of the formation of Mars, focusing on its primary constituents, its formation time scale and its small mass compared to Earth and Venus. I argue that the small mass of Mars requires the terrestrial planets to have formed from a narrow annulus of material, rather than a disc extending to Jupiter. The truncation of the outer edge of the disc ...

Summer highs occasionally reach 30°C (86° F), but it's still no picnic; the planet’s atmosphere is 95.3% carbon dioxide, and without a magnetic field its surface is bombarded by the Sun’s radiation. The low atmospheric pressure combined with cold ...
