Mars' cloudy sky as seen by Perseverance rover in 2023, sol 738.. The climate of Mars has been a topic of scientific curiosity for centuries, in part because it is the only terrestrial planet whose surface can be easily directly observed in detail from the Earth with help from a telescope.
The atmosphere of Mars has been losing mass to space since the planet's core slowed down, and the leakage of gases still continues today. [ 4 ] [ 8 ] [ 9 ] The atmosphere of Mars is colder than Earth’s owing to the larger distance from the Sun, receiving less solar energy and has a lower effective temperature , which is about 210 K (−63 °C ...

1995 photo of Mars showing approximate size of the polar caps. The planet Mars has two permanent polar ice caps of water ice and some dry ice (frozen carbon dioxide, CO 2).Above kilometer-thick layers of water ice permafrost, slabs of dry ice are deposited during a pole's winter, [1] [2] lying in continuous darkness, causing 25–30% of the atmosphere being deposited annually at either of the ...
The idea of transforming Mars into a world more hospitable to human habitation is a regular feature of science fiction. Scientists are now proposing a new approach to warm up Earth's planetary ...
"Reach for the Stars" was written in February 2011, after NASA asked will.i.am to write and produce a song for the Curiosity rover's landing on Mars. The songwriter said that the experience with NASA administrator Charles Bolden discussing the possibility of broadcasting a song from Mars was "surreal", The song is part of NASA's educational outreach, with will.i.am stating that the song "aims ...
The zodiac constellations of Mars's ecliptic are almost the same as those of Earth — after all, the two ecliptic planes only have a mutual inclination of 1.85° — but on Mars, the Sun spends 6 days in the constellation Cetus, leaving and re-entering Pisces as it does so, making a total of 14 zodiacal constellations.
Mars is a terrestrial planet with a surface that consists of minerals containing silicon and oxygen, metals, and other elements that typically make up rock. The Martian surface is primarily composed of tholeiitic basalt , [ 59 ] although parts are more silica -rich than typical basalt and may be similar to andesitic rocks on Earth, or silica glass.
