Scientists engineer microbe to help humanity settle Mars
"On Mars, nature will do the same jobs for us that she does on Earth — create fertile soil, shelter, oxygen and food."

A new genetically engineered microbe may one day help humanity settle Mars, a nonprofit biotechnology research startup suggests.
Our species has launched nearly 50 missions to Mars since 1960, all of them robotic. If everything goes according to plan, they've all been building toward crewed Red Planet flight, which remains a high priority for national space agencies and private companies alike.
Ideally, human crews there will not rely on shipment after shipment from Earth, but can instead make use of any resources they can unearth on Mars for air, food, water, building supplies and more. Perhaps the most radical possible outcome from this approach is the concept of terraforming Mars — transforming the cold, arid world to support life as we know it.
Now, researchers at Pioneer Labs in Emeryville, California, have developed a microbe they suggest may be a useful, safe first step toward terraforming Mars.
"On Mars, nature will do the same jobs for us that she does on Earth — create fertile soil, shelter, oxygen and food," Erika DeBenedictis, CEO of Pioneer Labs, told Space.com.
A key problem with the idea of terraforming Mars is that the Red Planet's surface is essentially toxic. While raw materials potentially useful for Earth life are found in abundance on Mars, they are mixed in the soil with toxins such as perchlorate, as well as salts that would make growth difficult for most organisms.
Previous strategies for growing plants on Mars included rinsing these poisons out, bringing supplemental fertilizers from Earth, or avoiding Martian soil entirely and using hydroponics. However, Pioneer Labs argues that these approaches do not scale up well in terms of time and expense.
Today, Pioneer Labs is announcing our first step towards terraforming Mars. 🚀🌼
With equipment that fits in just a single rocket launch, we can convert Martian dirt, water, and air into enough building materials to construct a small city on Mars.
To do it, we made the first microbe for Mars. We found the best microbe on Earth and used evolution to teach it how to source all of its nutrients directly from Martian materials.
The first astronauts will be greeted with safe shelter already filled with water, oxygen, and rocket fuel for the return journey.
This is the first step toward using biology to make Mars a friendly place for life. It lets us live off the land and helps us build the next great frontier.
