La capsula Dragon della Space X - mandata in orbita a luglio attraverso un razzo della Falcon 9 - è rientrata sulla Terra dalla Stazione spaziale internazionale (ISS) carica di esperimenti scientifici. La missione si è conclusa con un tuffo nell’Oceano Pacifico al largo della California meridionale.
La dozzina di sperimentazioni trasportate fanno ritorno per essere completate e per l’analisi dei risultati. Si va dalla realizzazione di serbatoi di carburante flessibili, allo studio in orbita del comportamento di alcune proteine legate al cancro, fino alle ricerche inerenti la crescita dei batteri e dello sviluppo di muscoli e ossa in topi di laboratorio in condizioni di microgravità.
Di uno di questi esperimenti ne parla l’astronauta italiano Luca Parmitano in un tweet. “Biorock – scrive Parmitano - studia batteri che sono in grado di estrarre basalti e graniti, e che un giorno potrebbero essere utili su altri pianeti”.
