Water on Mars: Fact or Fiction?

Scientists have found evidence of water on Mars, both in frozen form at the poles and as vapor in the atmosphere. Recent discoveries suggest there might even be liquid water under its surface, raising hopes for the potential of life.

  1. Evidence suggests liquid water exists under Mars' surface.

The Largest Volcano in the Solar System

Mars is home to Olympus Mons, the largest volcano in the solar system. Towering about 22 km (13.6 miles) high, it's nearly three times the height of Mount Everest, Earth's tallest mountain. Unlike Earth's volcanoes, Olympus Mons has a wide, flat profile due to Mars' lower gravity.

  1. Olympus Mons on Mars is three times taller than Mount Everest.

Martian Moons: Phobos and Deimos

Mars has two small moons, Phobos and Deimos, believed to be captured asteroids. Phobos, the larger of the two, is gradually spiraling towards Mars and is expected to either crash into Mars or break apart to form a ring around the planet in about 50 million years.

  1. Phobos is doomed to eventually crash into Mars or form a ring around it.

How Long is a Year on Mars?

A year on Mars is almost twice as long as a year on Earth, lasting about 687 Earth days. This is because Mars is further from the Sun, taking longer to complete one orbit.

  1. A Martian year lasts 687 Earth days.

The Temperature Range on Mars

Mars experiences a wide range of temperatures, from a maximum of about 20°C (68°F) near the equator during summer to a minimum of about -125°C (-195°F) near the poles during winter. These extreme variations are due to its thin atmosphere and distance from the Sun.

  1. Temperatures on Mars can drop to -125°C (-195°F).

The Possibility of Life on Mars

While Mars is currently a frozen desert, there is evidence that it was once warmer and had liquid water on its surface. This has led scientists to speculate about the possibility of life, though no definitive evidence has been found yet.

  1. Mars might have supported life in the past.
