NASA’s Mars Reconnaissance Orbiter has been orbiting Mars since 2006, but some recent pictures taken by the powerful camera aboard this vessel are giving us something new to consider. The camera, HiRISE, allows us to see extremely detailed images from the Mars and showed some craters that give scientists reason to believe there is presence of flowing, liquid water. Since this type of water is an essential ingredient for life on any planet, it could change what we know about Mars.

There are several images of long brown streaks that appeared in the Martian spring and summer. These streaks weren’t visible during the cold season and this causes scientists to believe they might be flowing water. There is no proof of water on Mars, but the images help to support the evidence that other probes have reported, such as the existence of deep Martian canyons that water may have carved out. The water would most likely be very salty, explaining its low freezing point. This would also be because Mars is so much farther away from the sun than Earth, around 35 million miles farther.
