The future of space exploration depends on bridging the gap between biology and technology, and scientists at NASA Ames are building the digital bridge.
Published on: July 2023
Imagine a future where astronauts bound for Mars can run thousands of virtual medical experiments before ever leaving Earth, where spacecraft autonomously diagnose and counteract the effects of deep space radiation on human cells, and where biological 3D printers can produce vital nutrients on demand during a multi-year mission. This isn't science fiction—it's the future being built today at NASA's Ames Research Center, where a revolutionary fusion of biology, computing, and space technology is preparing humanity for its next giant leap.
The greatest challenges of long-duration spaceflight are not just engineering problems; they are biological ones. Away from Earth's protective magnetic field, astronauts are bombarded with higher levels of space radiation that can damage DNA and increase cancer risk 6 . The microgravity environment has a wide range of harmful effects, from weakening bones and muscles to altering immune system function 6 . Furthermore, missions to the Moon and Mars will be too long to bring all necessary supplies, meaning crews will need to produce their own medicines and nutrients on-demand .
To tackle these challenges, scientists at NASA Ames are pioneering a field we might call Biological Visualization, Imaging, and Simulation (Bio-VIS). This involves creating sophisticated digital twins of biological systems, developing AI to interpret biological data in real-time, and building virtual testing environments that can predict how life will behave in the harshness of space. As one Ames report notes, the goal is to "advance space exploration by achieving new scientific discoveries and technological developments in the biological sciences" 2 .
At the heart of this revolution is the AI for Life in Space (AI4LS) team. This group builds advanced computational frameworks that use machine learning and artificial intelligence to model, predict, and mitigate spaceflight risks 2 . Their work turns complex biological data into actionable insights.

These digital tools are crucial for managing the health of astronauts on long-duration missions, where communication delays with Earth make real-time guidance from ground control impossible. The Intelligent Systems Division at Ames develops technologies for "Integrated health management" and "systems safety," creating intelligent systems that can monitor astronaut health and the state of biological experiments autonomously 4 .
One of their key platforms is Astrobee, NASA's free-flying robotic assistant on the International Space Station (ISS). Astrobee can be equipped with sensors to monitor the station's environment and, with the right AI software, could eventually check on biological experiments or even the crew's well-being, providing a mobile, intelligent eye inside the orbiting laboratory 4 .
In December 2022, a shoebox-sized spacecraft called BioSentinel made history, carrying living organisms farther from Earth than ever before—over one million miles 8 . This ambitious mission serves as a perfect case study of how NASA Ames is integrating technology and biology.
BioSentinel's experiment is elegant in its simplicity and profound in its implications. Aboard the CubeSat are microorganisms in the form of yeast—the very same yeast used in baking bread and brewing beer 8 . Why yeast? Because yeast cells share fundamental biological mechanisms with human cells, particularly in how their DNA is damaged and repaired 8 .
The experiment was designed to run automatically over five to six months. On December 5, when BioSentinel was 655,730 miles from Earth, the team at Ames sent commands to initiate the study 8 . The spacecraft's miniature laboratory began monitoring how the yeast responds to the genuine deep space radiation environment beyond Earth's protective magnetosphere.
| Launch Date | Aboard Artemis I (November 2022) |
|---|---|
| Spacecraft Type | 6U CubeSat (roughly shoebox-sized) |
| Biological Model | Saccharomyces cerevisiae yeast |
| Key Measurement | DNA damage and repair in deep space |
| Unique Aspect | First long-duration biology study in deep space |
| Mission Duration | 5-6 months of continuous experimentation |
While BioSentinel's full results are still being analyzed, the mission has already demonstrated the ability to conduct remote biological experiments in deep space. The data it collects will fill critical gaps in knowledge about the health risks posed by space radiation 8 .
This is vital because, as NASA prepares for Artemis missions to the Moon and eventual journeys to Mars, understanding the biological impact of persistent radiation exposure is crucial. Ground facilities cannot fully simulate the dynamic and unique composition of the deep space radiation environment, making real-world experiments like BioSentinel indispensable 2 .
| Hardware | Function | Significance |
|---|---|---|
| WetLab-2 | Enables real-time gene expression analysis in space 3 | Allows immediate results without waiting to return samples to Earth |
| RAZOR EX | Rapid microbial detection system using PCR technology 3 | Can identify pathogens in less than an hour to protect crew health |
| MinION | Commercial DNA sequencer for identifying unknown microbes 3 | Lets crew know what is in their environment and take appropriate action |
| miniPCR | Tool that replicates targeted pieces of DNA for analysis 3 | Used to study how spaceflight affects the immune system at a genetic level |
The future of space biology relies on a sophisticated toolkit that blends cutting-edge biotechnology with advanced computational systems. These tools work together to create a comprehensive picture of biological processes in space.

The ultimate goal is a future where instead of packing all supplies for a multi-year mission to Mars, astronauts can "make it there, not take it there" . This could include using carbon dioxide and water to feed microbial systems that produce everything from food and medicines to plastics and construction materials .
The work happening at NASA Ames Research Center represents a fundamental shift in how we approach space exploration. By creating digital twins of biological processes, developing AI capable of interpreting complex living systems, and building virtual testing environments, scientists are not merely observing biology in space—they are learning to predict, control, and sustain it.
This fusion of the biological and digital worlds is creating a new paradigm where computational models and virtual simulations will help protect actual human lives on their journey to other worlds. As we prepare to send humans back to the Moon and onward to Mars, these technologies ensure that our greatest asset in exploration—the human body—will be protected, understood, and sustained through the most challenging environments imaginable.
The silent, digital revolution in space biology is already underway, and it's building a safer path for humanity among the stars.
