Des satellites de l\u2019ESA comme Envisat et Sentinelle 1 nous ont assist\u00e9s dans cette mission. Les nuages bloquent occasionnellement la vue des satellites, mais un \u00e9quipement radar leur permet de voir \u00e0 travers les formations nuageuses pour observer les glaciers. Malgr\u00e9 tout, les scientifiques peuvent parfois manquer de donn\u00e9es sur certains endroits ou moments. Pour combler ce manque, ils utilisent des logiciels avanc\u00e9s de simulation pour mieux comprendre ce qui arrive \u00e0 ces glaciers.<\/p>\n<p>Les satellites de l\u2019ESA vont continuer \u00e0 surveiller les glaciers en prenant des photos et en collectant de pr\u00e9cieuses donn\u00e9es.
