Water on Mars may be more widespread and recent than previously thought, a new study suggests.
Water may be more widespread and recent on Mars than previously thought, based on observations of Martian sand dunes by China's rover.
Its solar panels are likely covered with dust, choking off its power source and possibly preventing the rover from operating again, said Zhang Rongqiao, the mission's chief designer. Conditions during that period were similar to now on Mars, with rivers and lakes dried up and no longer flowing as they did billions of years earlier.
The rover did not directly detect any water in the form of frost or ice. But Qin said computer simulations and observations by other spacecraft at Mars indicate that even nowadays at certain times of year, conditions could be suitable for water to appear.

China's Mars rover finds signs of recent water in sand dunesA new study suggests water on Mars may be more widespread and recent than previously thought. Scientists reported the finding from China's Mars rover in Science Advances on Friday. The rover spotted cracks and crusts in the Martian salt-rich dunes. Small pockets of water from thawing frost or snow, mixed with salt, likely resulted in the cracked surface. The six-wheeled rover was launched in 2020 and arrived at Mars in 2021. It spent a year roaming the Martian surface before going into hibernation. It's yet to wake up, after almost a year. Researchers say the rover's solar panels are likely covered with dust, choking off its power source.
