The newest National Aeronautics and Space Administration findings in the most famous planet of our solar system have finally unveiled the mystery regarding the NASA Mars Rover Curiosity: a lake!

The latest NASA Mars Rover Curiosity lake discovery has solved a longtime mystery, ever since the robotic rover first came into the planet's orbit, when it landed in a mountain, which was forming a sort of deep bowl in the middle of the red planet.

According to BBC, the NASA Mars Rover Curiosity's lake discovery was made after scientists came to the theory that the huge 5km-high mountain in the Mars Gale Crater is actually the remainder of a succession of lakes that were filling up the space where now only a deep bowl can be seen.

The findings of the NASA Mars Rover Curiosity's lake could potentially mean a huge breakthrough in regards of how things have been in the past for the Red Planet, as this would imply that billions of years ago, the planet had to be warmer and wetter, and thus able to host a wide variety of life.

The Independent says that the new NASA Mars Rover Curiosity's lake discovery means that the new information the rover has collected states that, about 3.5 billion years ago, the planet had a climate so varied that it couldn't only host lakes, but it could even go as far as having had rains and snow.ç

"Knowledge we're gaining about Mars' environmental evolution by deciphering how Mount Sharp formed will also help guide plans for future missions to seek signs of Martian life," said Michael Meyer, the lead scientist for NASA's Mars Exploration Program, to The Daily Mail.

News of the NASA Mars Rover Curiosity lake discovery comes only days after the test launch of NASA's Orion, the project that is aiming to put astronauts on the surface of the Red Planet.
