La sonda cinese Tianwen 1 diretta verso Marte e destinata a diventare il primo veicolo della Cina a entrare nell'orbita del Pianeta rosso è stata lanciata giovedì mattina. Il lancio è avvenuto dalla base di di Wenchang, sull'isola di Hainan, e ha segnato anche l'esordio del razzo Lunga Marcia 5. La Cina entra così nella corsa verso Marte, a pochi giorni dalla partenza della sonda Hope degli Emirati Arabi Uniti e precedendo di circa una settimana la partenza del nuovo rover della NASA, Perseverance.
La sonda Tianwen 1, il cui nome significa "Ricerca della verità celeste" ha cominciato così il suo viaggio verso Marte, dove l'arrivo è previsto nel febbraio 2021. La missione prevede di portare sia un veicolo nell'orbita marziana sia un rover destinato a esplorare la superficie del pianeta rosso grazie a 13 strumenti. L'obiettivo è studiare l'atmosfera marziana, la struttura interna e la superficie del pianeta, con una particolare attenzione alle tracce della presenza di acqua e a eventuali segnali di forme di vita.

Quello odierno è il secondo lancio di un veicolo cinese diretto verso Marte. Il primo risale al 2011, quando la sonda Yinghuo 1 era andata perduta, con il fallimento della missione russa Phobos-Grunt, non riuscendo immettersi nella posizione corretta nell'orbita terrestre ciò che ne aveva causato il rientro nell'atmosfera terrestre prima di inabissarsi nell’Oceano Pacifico nel gennaio 2012.
