  1. Top Five Incredible Facts About Mars By: Nicholas Zubrick

  2. 1: Scientists observed a Martian “civilization” just last century The astronomer William Herschel made some important observations of Mars, including its rotation period and the seasonal variation of its ice caps. But, like many of his era, he also worked under the assumption that the planet was teeming with life.. He suggested that intelligent Martians “probably enjoyed a situation similar to our own.” Nicholas Zubrick

  3. 2: Valles Marineris is the grandest canyon in the Solar System Valles Marineris cuts a deep scar across 20% of the circumference of Mars, extending an incredible 2,500 miles around the planet. It begins in the maze-like valleys of the NoctisLabyrinthus (‘labyrinth of the night’) in the west and abates in the smooth ChrysePlanitia (‘golden plain’) to the northeast. Nicholas Zubrick

  4. 3: The moons of Mars have different fates Phobosis a mere 43 miles around and Deimos is just 24 miles. Because of their irregular shapes, they’re actually thought to be captured asteroids caught in Mars’s gravitational pull. And because of their diminutive size, they both have very little gravity of their own. On Phobos, for example, you could easily throw a baseball into escape velocity, while on Deimos you could ride a bike off a hill into space. Nicholas Zubrick

  5. 4: The Red Planet used to be blue While notions of organized life on the surface of Mars have long since been quashed, we now know the planet has water. And billions of years ago, it almost certainly had rivers, lakes, and seas just like the Earth. Digital visualizations give us a glimpse of what this may have looked like—either from within the early Martian atmosphere or from without, looking at the planet from space. Nicholas Zubrick

  6. 5: There may be life on Mars right now Because Mars lost its atmosphere and the majority of its water gradually, over a period of millions or billions of years, it’s possible—even likely—that life evolved to survive the increasingly inhospitable conditions.Backin 1975, the year before the first Viking lander returned data and samples from the surface, Martians were envisioned as ground-based and fungal in appearance.
