The space shuttle program might be over, but NASA's still hard at work. The agency recently released data and photos that suggest that Mars might have flowing water during its warmer months.
Using 3D imaging, NASA studied Mars's terrain over the planet's four seasons, and found that water appeared to be flowing down slopes during spring and summer, and that these streams disappear completely in winter. NASA discovered these possible water flows in the middle latitudes of the planet's southern hemisphere, and the water is believed to be briny (i.e. slightly salty).
NASA's data show that there are at least 1,000 long and separate flows of water off these slopes. It's also worth noting that in the northern hemisphere, scientists previously discovered evidence of frozen pools of water and geological changes, such as new slopes and gullies.
