- •
New CubeSat payload to in-situ sense pentacene degradation due to ATOX erosion in LEO.
- •
Sensing strategy is mass loss detection, using a MEMS resonator.
- •
Different mechanical vibration modes of the MEMS are used.
- •
Data is sent to the ground in real-time during the mission.
- •
Ground tests indicate that mass losses around 1e-12 kg can be detected.
