La società privata statunitense SpaceX ha lanciato sabato alle 21:25, ora svizzera, la sua capsula Dragon senza pilota a bordo di un suo razzo Falcon 9 con destinazione la Stazione spaziale internazionale (Iss), allo scopo consegnare rifornimenti e attrezzature. Dragon trasporta pure cellule immunitarie per una ricerca dell'università di Zurigo.
Lo studio diretto dal biologo dell'istituto di anatomia dell'ateneo zurighese Oliver Ullrich mira a osservare il comportamento delle cellule umane in assenza di gravità.
È noto che ossa e muscoli perdono massa e che le cellule del sistema immunitario funzionano male. Il lavoro di Ullrich si focalizza su un gruppo di queste ultime, i cosiddetti fagociti. L'indebolimento del sistema immunitario espone più facilmente gli astronauti a infezioni di ogni tipo.
