Alors que Perseverance se posera sur la plan\u00e8te rouge le 18 f\u00e9vrier, il faudra attendre plus longtemps Tianwen-1 qui se met d’abord en orbite martienne. Le module de descente est cens\u00e9 se poser pour sa part en avril, dans les plaines bor\u00e9ales d’Utopia, avec pour mission de d\u00e9livrer au sol le premier rover martien chinois, d’une masse de 240\u00a0kg. C’est le double en masse des deux rovers Yutu du m\u00eame pays, qui circulent \u00e0 l’heure actuelle sur la Lune, bien qu’on soit loin de la masse de Perseverance (1025 kg), Curiosity (900 kg), ou m\u00eame de la g\u00e9n\u00e9ration pr\u00e9c\u00e9dente de rovers am\u00e9ricains, Spirit et Opportunity (175 kg). \u00a0Mais Tianwen-1 a d\u00e9j\u00e0 des ambitions, avec un radar pour sonder le sol et un spectrom\u00e8tre pour se lancer \u00e0 la recherche de mati\u00e8re organique, voire vivante sur Mars.<\/span><\/p>\r\n

Les ambitions chinoises sont multiples. En ce mois de d\u00e9cembre 2020, nous assistons avec Chang’e 5 \u00e0 une tentative de retour automatique d’un \u00e9chantillon de sol depuis la Lune, bien engag\u00e9 puisque la capsule avec l’\u00e9chantillon a d\u00e9j\u00e0 quitt\u00e9 les champs de lave de Rumker Hills, dans l’oc\u00e9an des Temp\u00eates, et est attendue sur Terre le 16 d\u00e9cembre.<\/p>\r\n

En parall\u00e8le \u00e0 ces missions automatiques, on attend d’un mois \u00e0 l’autre la prochaine mission pilot\u00e9e chinoise en orbite terrestre qui \u00e9trennera le nouveau vaisseau spatial de 14 tonnes (\u00e0 vide) capable de loger jusqu’\u00e0 7 astronautes \u00e0 la fois, et surtout d’entreprendre des vols de longue distance, notamment \u00e0 destination de la Lune.<\/p>\r\n
