The way the system works:
A printed plastic array of yeast + nutrient broth in tiny voids are placed in front of a detector.
At rest, these yeast are dormant. However, when radiation from cosmic and solar sources cause double-stranded breaks in the yeast's DNA, they become metabolically active.

There's both a normal ("wild type") version of the yeast, and also an engineered strain that has defective ability to repair DNA damage, to determine how efficiently cellular mechanisms can handle the accumulation of radiation damage.

deep is anything beyond earth’s gravitational dominance. biosentinel is in a slightly eccentric solar orbit it at 1AU that, IF I REMEMBER CORRECTLY, causes it to drift away from and close to the planet on an 18mo cycle but it is dominated by the sun not by earth

In May 2024, a remarkable geomagnetic storm, also known as solar storm, impacted Earth, resulting in vibrant auroras that captivated observers worldwide. These stunning natural displays occur when eruptions of solar plasma, known as coronal mass ejections, collide with Earth's magnetic field. While these events are a visual delight, they also raise significant questions about the impact of solar radiation on humans travelling beyond Earth's atmosphere.
