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 Earth with help from a telescope.
At one point, 1.35 million Earth years ago, Mars had an eccentricity of roughly 0.002, much less than that of Earth today. [188] Mars's cycle of eccentricity is 96,000 Earth years compared to Earth's cycle of 100,000 years. [189] Mars has its closest approach to Earth in a synodic period of 779.94 days.
Although there is abundant geologic evidence for surface water early in Mars history, the nature and timing of the climate conditions under which that water occurred is a subject of vigorous scientific debate. [15] Today Mars is a cold, hyperarid desert with an average atmospheric pressure less than 1% that of Earth.
While astronomers say it’s not a “perihelic opposition,” which happens every 15-17 years and only occurs when Mars is at its closest to Earth while also reaching the closest point to the sun ...
The Noachian period occurred from 4.1 to 3.7 billion years ago, and little is known from direct measurements dating to the pre-Noachian period on Mars, between 4.5 billion and 4.1 billion years ...
NASA’s Perseverance Mars rover used its right-front navigation camera to capture this first view over the rim of Jezero Crater on Dec. 10, 2024, the 1,354th Martian day, or sol, of the mission.
Temperatures on Mars from REMS on the Curiosity Rover (August 16/17, 2012). Rover Environmental Monitoring Station (REMS) is a weather station on Mars for Curiosity rover contributed by Spain and Finland. [1] [2] REMS measures humidity, pressure, temperature, wind speeds, and ultraviolet radiation on Mars. [3]
Researchers have uncovered what may be the oldest direct evidence of hot water activity on Mars, suggesting the red planet could have supported life billions of years ago.. Scientists at Australia ...
