The search for life on the Red Planet presses on as NASA’s Perseverance rover prepares to lift off this Thursday July 30 to study the planet and search for signs of ancient life. But this isn’t the first investigation into the habitability of ancient Mars, as previous orbiters, landers and rovers have taken significant strides in the search for life. So, what do we know about possible life on Mars? Let’s explore what previous missions and studies have uncovered about Mars and the creatures that may have once lived there.

There are records of people studying Mars dating all the way back to the second century BCE, when ancient Egyptian astronomers were observing planets, stars and constellations in the night sky. Later on, through the centuries, more and more detailed descriptions of the Red Planet began popping up, leading up to the first telescopic observation of the planet in by the Italian astronomer Galileo Galilei.

With more advanced telescopic and orbital observations of the planets many years later, scientists learned that, up until about 3. While the planet’s atmosphere was stripped away scientists think that powerful solar storms could have been a major factor in the loss of atmosphere , researchers still think that it’s very possible that microscopic life could have existed in the time that Mars was more “Earth-like. However, they think that if life existed on Mars, it was most likely microscopic — not the green and gray aliens from science fiction.

Researchers believe that if life evolved on Mars similarly to how it did on Earth, it could have happened more than 3.
