Is there life on Mars? More and more evidence seems to suggest that the red planet could once support life. Possibly, the planet Mars might still be habitable today. Life needs a clean water which may have covered Mars billions of years ago. Some of the earliest evidence came from orbiting satellites which snapped photos landscapes formed by water erosion. When Curiosity arrived, more clues poured in. In 2012, the rover discovered the signs of streambed. Leading the fact that river once flow for a Gale Crater.
Ancient Lake Found on Mars
Recently, it came across to the remains an ancient lake. 3.6 billion of years ago that lake was filled with fresh water as well as chemicals that could have supported microbial life. Also, when the Mars rover first used its drill to take a rock sample found clay minerals. These formed in slightly salty but still drinkable liquid water.
Life on Earth are Possibly Originated from Mars?
Ancient Mars might actually have been a better place for life than our own planet. According to geochemist Steven Benner, life could develop their first. Billions of years ago Mars had more oxygen than Earth Better think this was a better environment for developing molecules like RNA. Which are the building blocks of life. In fact, there goes even further and suggests martian molecules might seeded life on Earth. Asteroid strikes could hurl the molecules towards Earth on the backs of Martian rocks. Although this theory is exciting not everyone agrees. The process that leads to RNA formation is still not entirely understood. So, these molecules could have developed independently in many locations.
Martian Object Fell on Earth
If you don't like travel the space to visit the planet. Look for martian life here on Earth. In 1996, NASA researchers claimed the meteorite ALH84001 contained evidence of ancient microbes. This space rock formed on Mars 4 billion years ago. When the planet was still watery. Samples from its interior contained the chemicals produced by microbes digest and decay. Even better, there were worm-like structures that looked-like a fossilized bacteria. But, this interpretation of the evidence could be wrong. The features of the meteorite may have been formed by physical processes rather than living creatures.
Does the Planet Still have Water Deposits Up to this Moment?
Mars may have been wet billions of years ago. But, does it still have water today? Absolutely YES! According to Curiosity's analysis. There are 2% of water found in the martian soil. Unfortunately, the water isn't drinkable because it's bonded to other minerals. However, researchers have also noticed that in spring and summer. Dark streaks tend to appear then lengthen on Martian slopes near the equator. These marks may be due to the float of salt water. Which would mean liquid water is abundant near the Martian surface.
Organisms from Earth Could Now Living on the Red Planet
Life is tough! It can even survive and habitats that mean mocking Mars. Several studies have placed microbial species in chambers with low pressure, low temperature, and carbon dioxide atmosphere. Most microbes can survive this simulated martian environment. They just lie dormant until they returned Earth-like conditions. Certain species can even continue to function. Which means organisms that survive NASA's cleaning processes hitched a ride to Mars could now be living on the red planet. Of course, they would have to deal with strong UV radiation and other obstacles. But, Mars may not be as inhospitable as we used to think.
