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 ...
While Mars's climate has similarities to Earth's, including periodic ice ages, there are also important differences, such as much lower thermal inertia. Mars' atmosphere has a scale height of approximately 11 km (36,000 ft), 60% greater than that on Earth. The climate is of considerable relevance to the question of whether life is or ever has ...

NASA’s Perseverance rover has collected a sample from Mars that has textures “unlike anything we’ve ever seen before.”. Known as “Silver Mountain,” the rock core has been sealed into a ...
Mars has only about 0.7% of the atmospheric pressure of Earth. Mars' atmosphere is about 6.5 millibar, Earth's atmosphere is 1013 millibar. Surface of Mars is like Earth at 100,000 feet (30 kilometres) in the stratosphere. [19] [20] Mars' atmosphere's humidity is 0.03%, Earth's average humidity is about 50% (lowest 0.36%, high 100%).
When Gov. Gavin Newsom said this week that California would ban the sale of gas-powered cars by 2035, he left no doubt about why he was issuing the order now. “Our cars shouldn’t make ...
