ROSINA's cometary pressure sensor (COPS)
The Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) is a combination of two mass spectrometers and a pressure sensor:
- the Double Focusing Mass Spectrometer (DFMS)
- the Reflectron Time-of-Flight (RTOF) mass spectrometer
- the Comet Pressure Sensor (COPS)
This photo shows the COPS pressure sensor.
