23.The journey to the moon has been the first step towards future exploration space.The distance between the moon and the earth is very short indeed when compared the distances between earth and the other planets.Mars,the nearest planet to Earth is millions of miles away!Traveling to the planets will be man's next aim.Such travels will be more challenging (挑戰(zhàn)) than the trip to the moon and certainly more adventurous (冒險(xiǎn)). Recently,two American spaceships,Vikings 1 and 2,landed on Mars trying to discover whether that planet has any life on it.So far the signs of life on Mars has neither confirmed(確認(rèn)) nor ruled out.Russians have discovered that the surface of Venus (金星) is so hot that it is almost certain that there is no life there.Also the atmosphere of Venus is extremely dense (稠) and the pressure is nearly a hundred times greater than that of the earth's atmosphere.
