Mars rover under pressure to reach mountain goal

摘要

Seven months after it hurtled to a landing on Mars, NASA's Curiosity rover has rolled just 738 metres across the surface. It remains about 10 kilometres from its primary goal: Aeolis Mons, a 5-kilometre-high mountain thought to contain layers formed in ancient ponds. With the mission nearly one-third of the way through its allotted two years, the science team is beginning to feel the pressure to get moving.
