On the afternoon (in Paris) of Tuesday 20 March 2018 PicSat suddenly fell silent, after two successful morning passes over Europe. Attempts to re-establish contact have failed, nothing has been heard from the satellite, no sign of life. There was a short-lived hope that PicSat was heard on Friday 30 March by a team at the Morehead State University, but it radio amateur W2RTV was the first to manage to decode the faint signal and turned out to be another satellite (TIGRISAT). Today, Thursday 5 April 2018, the team decided to call mission-closed. A “pot” (French for party / drink) was organised at noon at the Paris Observatory in Meudon. Sylvestre Lacour did a short speech. Four radio amateurs who have been PicSat fans and great supporters joined in via a dedicated Google Hangout. A short video can be seen here. The team will continue to try to understand what went awry, while plans for new projects are being made. PicSat was operational for over 10 weeks. From a technological point of view it has been a success for the LESIA laboratory of the Paris Observatory – PSL, for whom PicSat has been the very first nano-satellite complete built and opereated in-house. This experience will open doors for new nano-satellite projects in the (near) future.
