Article Synopsis
- Small satellite technologies like CubeSats are revolutionizing space research, particularly in the field of biology and astrobiology.
- Over the past 15 years, NASA Ames Research Center has launched several biological CubeSats to study how space conditions affect microorganisms, focusing on factors like radiation and microgravity.
- The latest CubeSat, BioSentinel, aims to be the first to operate in deep space and will conduct experiments on DNA damage repair in cells, utilizing new advancements in its biosensing payload for long-term studies.
We report the first science results from the Space Environment Viability of Organics (SEVO) payload aboard the Organism/Organic Exposure to Orbital Stresses (O/OREOS) free-flying nanosatellite, which completed its nominal spaceflight mission in May 2011 but continues to acquire data biweekly. The SEVO payload integrates a compact UV-visible-NIR spectrometer, utilizing the Sun as its light source, with a 24-cell sample carousel that houses four classes of vacuum-deposited organic thin films: polycyclic aromatic hydrocarbon (PAH), amino acid, metalloporphyrin, and quinone. The organic films are enclosed in hermetically sealed sample cells that contain one of four astrobiologically relevant microenvironments.

The O/OREOS spacecraft was launched successfully to a 72° inclination, 650 km Earth orbit on 19 November 2010.
