In News: NASA’s Artemis I mission will send yeast to deep space with BioSentinel.

  • NASA’s BioSentinel will carry microorganisms to deep space to help scientists better understand the effects of deep space radiation on biological lifeforms.


  • The primary objective of BioSentinel is to monitor the vital signs of yeast to see how the microorganism fare when exposed to the radiation of deep space.
  • Yeast cells have biological mechanisms that are like human cells, including DNA damage and repair.
  • Due to this, scrutinising yeast in space will help us better understand the risks of space radiation to humans as the space agency plans missions to the Moon and beyond.
  • For this, BioSentinel will study yeast cell growth and metabolic activity after exposure to a high-radiation environment.
  • A key component of BioSentinel’s mission is a novel biosensor. NASA refers to it as a “miniature biotechnology laboratory” that is designed to measure how living yeast cells respond to long-term space radiation exposure.
  • BioSentinel is just one of the Artemis I mission’s ten secondary payloads that will hitch a ride to deep space.
  • All these satellites are mounted in the Orion stage adapter on the Space Launch System (SLS) rocket.
