火星忽而如烤箱,忽而如冰窖,辐射强烈;火星上的大气稀薄,不具保护性;那里常常遭到一连肆虐数周的沙尘暴袭击。生物能在这个星球上生存吗?科学家们希望“布里奇特号”火星探测器能为这一重要问题找到答案。 Suddenly, Mars, like an oven, flickers like an ice cave, radiates intensely; the atmosphere on Mars is thin and unprotected; it is often hit by dust storms that ravage for weeks. Bio-energy can survive on this planet? Scientists hope the “Bridget” Mars probe can find the answer to this important question.
