This is a picture //of a sunset on Mars// taken by NASA’s Curiosity rover //in 2013. Mars //is a very cold planet, //flooded with high levels of UV radiation// and extremely dry.// In fact, //Mars is considered //to be too dry //for life as we know it.
I’m an astrobiologist. I try to understand the origin of life on Earth and the possibilities of finding life elsewhere in the universe. People sometimes ask me, how can you be an astrobiologist if you don’t have your own spaceship?
Well, what I do is that I study life in those environments on Earth that most closely resemble other interesting places in the universe. All life on Earth requires water, so in my case I focus on the intimate relationship between water and life in order to understand if we could find life in a planet as dry as Mars. But since I do not have the 2.5 billion dollars to send my own robot to Mars, I study the most Martian place on Earth, the Atacama Desert.
Stressing important words
In another cave, we found a different type of microalgae. This one is able to use ocean mist as a source of water, and strikingly lives in the very bottom of a cave, so it has adapted to live with less than 0.1 percent of the amount of light that regular plants need. These type of findings suggest to me that on Mars, we may find even photosynthetic life inside caves. And by the way, that’s me.
Intonation and pauses for jokes
- How do I know this? Well, because I was born and raised in the Atacama.
- We may find even photosynthetic life inside caves. And by the way, that’s me.
- You already know the answer. Because I was born and raised in this desert.
