Mars is the fourth planet from the Sun in the Solar System. Named after the Roman god of war, Mars, it is often described as the “Red Planet” as the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the highest known mountain within the Solar System, and of Valles Marineris, the largest canyon. — Wikipedia

Liquid water beneath Martian south polar cap?
on January 25, 2022 at 5:40 pm
Scientists measured the properties of ice-brine mixtures as cold as -145 degrees Fahrenheit to help confirm that salty water likely exists between grains of ice or sediment under the ice cap at Mars' south pole. Laboratory measurements support oddly bright reflections detected by the MARSIS subsurface sounding radar aboard ESA's Mars Express orbiter.

Liquid water previously detected under Mars' ice-covered south pole is probably just a dusty mirage, according to a new study of the Red Planet. The finding challenges a 2018 study that appeared to find liquid water under Mars' south polar cap.

NASA's Curiosity rover landed on Mars on Aug. 6, 2012, and since then has roamed Gale Crater taking samples and sending the results back home for researchers to interpret. Analysis of carbon isotopes in sediment samples taken from half a dozen exposed locations, including an exposed cliff, leave researchers with three plausible explanations for the carbon's origin -- cosmic dust, ultraviolet degradation of carbon dioxide, or ultraviolet degradation of biologically produced methane.

Organic molecules found in a meteorite that hurtled to Earth from Mars were synthesized during interactions between water and rocks that occurred on the Red Planet about 4 billion years ago, according to new analysis.

NASA's Mars 2020 mission team has been working methodically and thoroughly, making good progress on understanding the best path forward to remove the uninvited pebbles from Perseverance's bit carousel. Over the previous weekend, and earlier this week, operational sequences were developed and tested to remove these rocky interlopers.

A team of researchers from several institutions in France, the U.S. and Sweden has used models of possible conditions on Mars to show that the red planet may have sported a northern ocean 3 billion years ago and that the climate was likely wet and cold. In their paper published in Proceedings of the National Academy of Sciences, the group describes theories to explain conditions on the surface of Mars today, and a model that simulated a wet and cold planet.
Looking up at the asteroids in the neighborhood
on January 19, 2022 at 2:08 pm
Asteroids fly through our solar system all the time, but it's rare for us to take notice of them. But that's changed this week, as an asteroid passes within 1,231,184 miles of Earth on January 18. The asteroid, dubbed 7482 (1994 PC1), was first seen in 1994 and is about two-thirds of a mile wide.
