USA-China exploration of Mars. Artwork of a future Mars mission,showing US and Chinese astronauts examining a rock on the Martian surface at sunrise,next to a flag marking this as Expedition 21. Their exploration rover is on the skyline at upper centre. Mars is a rocky desert world with no surface water and a gravity about one third of that on Earth. The atmosphere is mostly carbon dioxide and surface temperatures are well below freezing. Human missions to explore Mars have been planned since the 1950s,but as of 2010 none have come to fruition and current plans have been scaled back or cancelled | |
