Summary:

- NASA's Hubble and MAVEN spacecraft have helped solve the mystery of how Mars lost its water over time. The data from these missions suggests that the solar wind and radiation from the Sun have stripped away the planet's atmosphere, causing the water to be lost to space.

- The study found that the solar wind and radiation have been gradually stripping away the Martian atmosphere, causing the water in the atmosphere to be lost to space. This process has been ongoing for billions of years, gradually transforming Mars from a potentially habitable planet to the dry, barren world we see today.

- The findings provide important insights into the evolution of Mars and the loss of its water resources. This information can help scientists better understand the potential for life on other planets and the processes that shape the habitability of planetary environments.
