La sonda della NASA Maven (Mars Atmosphere and Volatile Evolution) è entrata nell'orbita di Marte, al termine di un viaggio durato 10 mesi e dopo aver percorso 711 milioni di chilometri.
Gli obiettivi principali sono due. Il primo è quello di analizzare l'alta atmosfera del Pianeta rosso, per aiutare gli scienziati a capire i suoi cambiamenti climatici, e in particolare le ragioni che hanno portato alla completa sparizione dell’acqua dalla sua superficie. Il secondo è quello di studiarne l’eventuale abitabilità.
Altre tre sonde (due statunitensi e una europea), come pure due rover della NASA, sono già impegnati a studiare il pianeta ed una sonda indiana dovrebbe arrivare mercoledì.
