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.
Curiosity's hard work is once again paying off by turning up evidence that liquid water quite likely exists on Mars at this time. A paper published in Nature Geoscience reveals that data collected ...
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 ...
The variation in Mars's surface water content is strongly coupled to the evolution of its atmosphere and may have been marked by several key stages. Head and others put together a detailed history of water on Mars and presented it in March, 2023. [300] Dry channels near Warrego Valles.
The average duration of the day-night cycle on Mars — i.e., a Martian day — is 24 hours, 39 minutes and 35.244 seconds, [3] equivalent to 1.02749125 Earth days. [4] The sidereal rotational period of Mars—its rotation compared to the fixed stars—is 24 hours, 37 minutes and 22.66 seconds. [4]
The presence of the water may mean big things for Martian biology as well as for our understanding of the planet’s history, but we are no closer to one day being able to live off the Martian land.
The thin atmosphere allows Mars to radiate heat energy away more easily, so temperatures near the equator can get up to 21 °C (70 °F) during a summer day, and then drop down to −73 °C (−99 °F) at night. [10] Subsurface conditions on Mars are dramatically more benign than those on the surface, which lead researchers to believe that if ...
These springs may be good places to look for evidence of past life because hot springs can preserve evidence of life forms for a long time. Location is Oxia Palus quadrangle. The Mars Reconnaissance Orbiter's HiRISE instrument has taken many images that strongly suggest that Mars has had a rich history of water-related processes. Many features ...
