英语听力:自然百科 金星和水星旅行指南 Venus and Mercury-19(在线收听

 Valor will be tackling the acid clouds of Venus with little help from flying pan technology. This being two weather balloons are we watched Venus in the mid-1980s. This with wagon machines there were two sep balloons that the Russians put them in the atmosphere. The one thing we knew it is, was put teflon on that hot balloon and the balloons worked perfect for two days just as design. And so we know, the teflon works. Battering violent updraft in acid clouds. These non stick pioneers were swept nearly half way around the planet. 

 
Calvin expects Valor to go further. We've second navigate the planet that is flying around the world of Venus not just once, but of that five times. And if we do that, we accomplish that we 'll by far have the world's record, actually the universal record for flight in the skies of any planet anywhere. Unexplored and unbelievable alien, the hot- zone planets are finally being recognized as prime space travel destinations. Mercury, a planet that both freezer and furnace. As a geologist, if I can just bring back one rock, one sample, I mean that would increase our knowledge of Mercury by, you know, nearly ten fold or sth. 
 
I hope like to go to these work craters looking at what is in it. Even if it's not water, it's sth very unusual, very fascinating. And Venus, our unfortunate twin sister. What we'd like to do explore the reason is haven't been explored before and so I would pick Elfogia here, that's probably the first place I would go. I love to go see those snow filled mountain peaks with metallic snow and see if we can figure what's going on there, maybe some new sports that could be created and sliding down those metallic snows. 
 
Many postulated the future story what's going to happen to earth and its future and that's another reason we're really interested in Venus because the ultimate fate of the earth is too, look like Venus looks today. Venus and Mercury, two planets of wonder, but trapped in their own alien house. Perhaps not obvious destinations to discover more about our home planet, but that's the beauty of travelling the solar system, it's just for, of surprises.
