Lessons Learned from the SD2 Operations on the Comet 67/P

Franco Bernelli-Zazzera, Amalia Ercoli-Finzi, Pierluigi Di Lizia


This work deals with the space systems devoted to drilling and sampling of low-gravity extra-terrestrial soils and, in particular, with the cometary instrument SD2 (Sampler, Drill and Distribution subsystem) onboard the lander Philae of Rosetta mission, which was in charge to drill and sample the comet 67/P Churyumov-Gerasimenko. The behaviour of SD2 is analysed from the commissioning and the payload check-outs performed during the ten-year trip to the in situ activity, by illustrating the consequences of the non-nominal landing of Philae. Then, the lessons learned from SD2 operation during the entire mission are illustrated, which could help the definition of the requirements for future similar operations.
