La sonda europea Rosetta, dopo un viaggio di 10 anni attraverso il Sistema solare, si è sistemata mercoledì mattina a 100 chilometri dalla cometa 67P/Churyumov-Gerasimenk (67P/TG). È il primo strumento spaziale a orbitare attorno a una cometa.
A 100 chilometri da 67P/TG
Per due settimane accompagnerà il corpo celeste a questa distanza per studiarlo in tutti i suoi dettagli. Pian piano poi si avvicinerà a 50 chilometri, ha spiegato l’Università di Berna in un comunicato e a inizio settembre si immetterà in un'orbita fissa a 30 chilometri da 67P/TG. Da lì la accompagnerà nella sua corsa verso il Sole.
L’obiettivo di Rosetta è trovare un luogo dove sganciare il suo modulo di atterraggio, chiamato Philae e ricco di attrezzatura scientifica all’avanguardia. Un’operazione molto delicata che non è mai stata realizzata prima.
L'avvicinamento di Rosetta alla cometa

Per Rosetta, che porta con sé anche molta tecnologia svizzera e la cui missione non terminerà prima di dicembre 2015, il lavoro è ancora molto.
