Dwarf Peas Breathe New Life into Space Habitat Research at Biosphere 2
Table of Contents
Tucson, AZ – A small, airtight habitat at the University of Arizona’s Biosphere 2 is yielding groundbreaking insights into sustainable food production for future space missions. researchers are cultivating dwarf peas within the Surface Atmosphere Modeling (SAM) system, demonstrating a potential pathway for providing food and oxygen for astronauts on long-duration voyages.
The SAM, a 6,000-square-foot enclosed system, mimics the conditions of a lunar or Martian habitat. This controlled habitat allows scientists to study how plants perform in isolation, crucial for understanding the challenges of growing food in space. the current experiment focuses on dwarf peas, chosen for their rapid growth cycle and nutritional value.
The SAM Habitat and it’s Significance
Biosphere 2, originally built in the early 1990s as a self-sustaining ecological system, now serves as a unique research facility. The SAM habitat, within Biosphere 2, is specifically designed to test technologies and strategies for creating life support systems for space exploration. This is about more than just growing food; it’s about creating a closed-loop system where plants contribute to air revitalization and waste recycling,
explains Dr. Gene Giacomelli, a professor at the University of Arizona and lead researcher on the project.
Did You Know?
Biosphere 2 was originally designed to house eight people for two years in a completely closed ecological system,a feat accomplished between 1991 and 1993.
The dwarf pea experiment is not the frist agricultural study conducted at Biosphere 2. Previous research has explored the growth of wheat, soybeans, and other crops. Though, the SAM habitat provides a more focused and controlled environment for detailed analysis. Researchers are meticulously monitoring factors such as light intensity, temperature, humidity, and carbon dioxide levels to optimize plant growth.
The success of this experiment could have significant implications for future space missions.Currently, astronauts rely heavily on pre-packaged food, which is expensive to transport and has a limited shelf life. Growing food in space would reduce reliance on Earth-based supplies and provide astronauts with fresh, nutritious produce.

The research team is also investigating the potential for using dwarf peas to recycle carbon dioxide, a byproduct of human respiration. Plants absorb carbon dioxide during photosynthesis, releasing oxygen in the process. This natural process could help maintain a breathable atmosphere within a space habitat. “The goal is to create a self-sustaining ecosystem where plants and humans can coexist harmoniously,
