Potential for life on Mars

Phoenix is returning some information that makes me happy. The conditions on Mars make it favourable to support life. That is, the soil and water that is there can make it possible to grow Earth plants on Mars. According to an article at, Mars has a possibility of being habitable to life. There is plenty of water, which has been analyzed by Phoenix. The soil has a chemistry that makes it possible to grow some plants. This does not mean that life exists on Mars now or in the past. But it means that when humans go to Mars, we can use the soil and water to grow food and to get drinking water. We could have a self-sustaining colony. Now, the only problem we need to solve is solar radiation. Mars’ weak magnetic field won’t block the solar radiation, which would kill the plants. In a properly shielded habitat, it would be possible. Now, my question is, can we terraform? From what I’ve heard, we’ll be able to grow plants there. This is exciting for the future!



  1. It’s good that the question has finally been answered. However, it’s not all that simple. They’ve also found an oxidizing substance that they say is “detrimental” to us. We’ve got a long way to go before we can actually see a benefit in the red planet.

  2. True. There are still many obstacles to overcome. It’ll take some work, but I believe solutions can be found.
