Mars is known as the "Red Planet." But it's not always russet-colored. Scientists have discovered that when humans go to Mars, they may find that occasionally the planet may have green skies.
For years, people have imagined the possibility of life on Mars. Now, though, researchers have taken a closer look at what techniques need to be used in order to find the possibility of life on the Red Planet.
Traffic around Mars is getting a bit busier. Last year's addition of two new spacecraft orbiting the Red Planet brought the total of active Mars orbiters to five, which is the most ever.
It turns out that Mars may possess briny water on its surface. NASA's Curiosity rover's data has indicated that water may exist under certain conditions.
Imagine soaring through space to Mars with the help of a solar sail. Sounds like something out of a science fiction movie, right? But it may just be possible.
Mars may just have liquid water. Scientist have found that it's possible the liquid water could exist close to the surface of the Red Planet.
Mars has polar ice caps, but it also has belts of glaciers at its central latitudes at both its northern and southern hemispheres. Now, scientists have calculated the size of these glaciers.
Scientists may have found more evidence for water on Mars.
Scientists have learned a bit more about an ancient lake system on Mars.
Settling on Mars isn't going to be easy, though plans are moving forward. Now, scientists have created an innovative new technique that may allow Martian colonists to harvest energy from carbon dioxide.
It turns out that Mars may have held more water than Earth's Arctic Ocean and covered a great portion of the planet's surface than the Atlantic. Scientists have found that the Red Planet was once watery, and that it lost its ocean over time.
