Covered with water billions of years ago, Mars has long been one of Earth’s most intriguing planetary neighbors, according to astronomers. The red planet is also a favorite destination of science fiction when imagining life outside of our home world.
The more scientists learn about Mars, the more likely it appears that it may have once been habitable, based on geological evidence. In ancient times, the planet was likely much warmer compared with the frozen desert it is today. NASA’s groundbreaking Pathfinder mission, which landed on Mars in 1997, made this discovery.
Since then, a number of missions have ventured to the red planet. These robotic explorers have been following a trail of evidence to understand more about the mysterious Martian past — and determine if life ever existed there.
