Abstract The Rosetta COSIMA data contains the operational history of the 72 dust collecting substrates from the installation inside the instrument. This dataset contains data from 2002-05-29 up to 2016-09-30. The operations are either expose, storage, spectra, peaks, scans, heating, imaging or grain lists. The data is grouped by the substrate and time. Up to the 2014-08 the aim of the data has been the instrument health and operational functionality, not statistically significant substrate background spectra. From 2014-08 onward the D0 substrate set was used to collect dust collected in the vicinity of 67P/CHURYUMOV GERASIMENKO 1 (1969 R1) and dust analysis with TOF-SIMS. From 2014-10-23 onward due to an instrument failure, the SIMS data became scientifically unusable. While other SIMS parameter sets were tested, substrates CF were exposed from mid 2015-12 and C7 from mid 2015-02. End of March 2015 SIMS became operational again. D1 and CD were exposed and SIMS was done with CD, CF and D1. In June TOF-SIMS was done with CF and D1. In July C7 was measured again, while CD was used for expose and TOF-SIMS up to October. D2 was exposed in September. Grains crushing was tested on D0 in February and March. C3 was used for expose from May. Emitter C extractor control voltage got a short in June and from August it was used with tip voltage control only. This data set supersedes all previous COSIMA datasets, like RO-C-COSIMA-3-V1.0, RO-C-COSIMA-3-V2.0, RO-C-COSIMA-3-V3.0, RO-C-COSIMA-3-V4.0, RO-C-COSIMA-3-V5.0, RO-CAL-COSIMA-2-V1.0 and RO-CAL-COSIMA-3-V3.0 Also, in the above previous versions, the values of the temperature in the HK data where given in Celsius although Kelvin was written in the description of the table in the FMT file. This was fixed in the version RO-C-COSIMA-3-V3.0.
Description Data Set Overview = This dataset contains data from COSIMA instrument in the Rosetta spacecraft. The set covers the substrate history from the calibration period of the instrument starting 2002-05-29 up to the end of the escort phase 4 2016-01-12. See the MISSION.CAT for a more detailed operations description. During the calibration period the instrument was operated with several software versions and for test purposes the operations were not always nominal. The substrate histories are anyway considered to be complete. During the first commissioning period from 2004-03-02 to 2004-06-06 the substrates from the target holder #D8 covering the dust inlet was stored. During the second commissioning period from 2004-09-06 to 2004-10-16 the first ever in space secondary ion mass spectra were generated. These can be found from the substrate #1C2 data. During the passive payload checkouts (PC) no science data was generated. The target holder #C2 was to be lifted to test the target manipulator unit. This failed in PC1 and PC3 due to hardware anomaly. Due to spacecraft telemetry problem, this history is not available from PC2 either. Test images from empty COSISCOPE slot were taken in all payload checkouts. All the substrates were also imaged in space to be used later as initial reference images. During the active checkouts the main operational concentration was to heal the baddly behaving ion emitter A. During those operations some spectra was acquired, but without intention to generate really scientifically usable background spectra from the substrates. During the prelanding phase, the COSIMA instrument was commissioned. The TOF-SIMS related voltage settings were optimised and COSISCOPE focused using the D8 substrates. From 2014-08-11 onward dust collection and the TOF-SIMS analysis was carried out with the D0 substrates. The TOF-SIMS measurements were done on selected dust particles on all D0 substrates. The ...

The spacecraft carries a Rosetta Lander, named Philae, to the nucleus and deploys it onto its surface. A brief description of the mission and its objectives can be found in [GLASSMEIERETAL2007A]. A detailed description of the mission analysis can be found in the ROSETTA User Manual [RO-DSS-MA-1001], and the flight Operations Plan [RO-ESC-PL-5000]. On its long way to the comet nucleus after a Launch by Ariane 5 P1+ in March 2004, the ROSETTA spacecraft orbited the Sun fo...
