If you were on the planet ____________________ , what you would ____________________ is the Sun ____________________ in the ____________________ ; then it would ____________________ into the ____________________ , and then the ____________________ would ____________________ at a certain ____________________ , move slightly ____________________ , stop ____________________ ; and then ____________________ ____________________ and set in the ____________________ . The way Mercury ____________________ on its ____________________ suggests that just beneath its ____________________ ____________________ ____________________ lies a ____________________ ____________________ ____________________ . it's so ____________________ that scientists believe it must be ____________________ from molten ____________________ blended with a little ____________________ ; and as for ____________________ , Nicholas declares : ? on ____________________ we don't talk about an ____________________ , but instead we talk about an ____________________ : that's to say , ____________________ which is very ____________________ : basically linked to ? outgassing' due to the ____________________ ____________________ . . .

Mercury has been known about for a ____________________ time . I mean the ____________________ already give ____________________ about the ____________________ of ____________________ , recognizing it as a ____________________ ; but real ____________________ of Mercury didn't start until much ____________________ . The first signs that ____________________ was more ____________________ than ____________________ came when the ____________________ ____________________ ____________________ flew by in ____________________ . It sent back ____________________ ____________________ of the surface and picked up ____________________ of a weak ____________________ ____________________ . Since ____________________ , the NASA probe ____________________ has been ____________________ ____________________ , mapping the ____________________ in ____________________ . it's picked up signs of ____________________ ____________________ , and of a ____________________ inner ____________________ , yet so much ____________________ to be ____________________ .
