The MAss Spectrometer for Planetary EXploration (MASPEX) is a
On 27 May 2016 it was announced that MASPEX was selected to fly on the mission.
Overview
MASPEX is a next generation spectrometer with significantly improved performance over existing instruments,
2), and small organic compounds (C2, C3, and C4) in complex mixtures.[3][4] MASPEX can also measure compounds in trace amounts (ppt), including the noble gases argon, krypton, xenon, and their isotopes.[3][4]
The MASPEX can operate in a heavy radiation environment, and can be baked to 300 °C for planetary protection against forward biological contamination in case the probe impacts any potentially habitable moon of Jupiter.[4] MASPEX can observe spatial features as small as 400 km of orbital track at high scan rates, and can operate at 5 kHz across full mass range.[4] Other areas of enhanced performance over existing instruments include:[4]
