È stata lanciata Cosmodromo di Baikonur, in Kazakistan, la navetta spaziale Soyuz che porterà sulla Stazione Spaziale l'americano Scott Kelly nella prima missione della durata di un anno mai organizzata dalla Nasa e destinata ad aprire la strada per i lunghi viaggi verso Marte.
I cambiamenti che avverranno in assenza di peso su Scott Kelly saranno confrontati con quelli del gemello identico Mark, che resta a Terra. Sulla Soyuz sono anche i russi Gennady Padalka e Mikhail Kornienko. Ad aspettarli sulla Stazione Spaziale l'astronauta italiana Samantha Cristoforetti.
