Yeast was chosen because it is both well-researched and repairs its DNA in a similar way to how the human body repairs its genetic material.
Two strains were chosen for the ride. One is a yeast commonly found in nature, while the other was selected because it has trouble repairing its DNA. Comparing how these two sets of microorganisms respond will provide new insights into the health risks associated with travel in deep space.and recharging its batteries in preparation for the start of its experiment, which is expected to begin next month, according to NASA.
"We're excited to see how the yeast are doing once the experiment begins and we receive the first data downlink from the spacecraft," said Matt Napoli, BioSentinel project manager at NASA Ames.
