This paper reviews the flight experiences of the BioSentinel propulsion and At-titude Determination and Control System (ADCS) teams. BioSentinel, a 6U CubeSat, launched as a secondary aboard the Space Launch System (SLS) maid-en flight in November of 2022 and is now operating in an Earth trailing helio-centric orbit. The development and performance of a novel approach to gyro bias estimation in the spacecraft’s Sun safe controller is discussed in detail. Further-more, the development and in-flight experience with the spacecraft’s propulsion system is discussed. Finally, we present the development and execution of an angular momentum management approach developed in flight after a propulsion system valve failure.
