A device combining a pulsed laser system with an Orbitrap mass analyser is well-suited for in situ exploration of prime astrobiological targets, such as Enceladus. Here a prototype of this instrument that is optimized for spaceflight applications demonstrates that this device could be used to characterize chemical biosignatures in future missions.
