Wheelock, who goes by the name @Astro_Wheels on Twitter. But then he has an almost unique vantage point - he is an astronaut aboard the International Space Station. Every couple of days, he tweets pictures to his followers. We present some of them here, but to see more, simply follow @Astro_Wheels on Twitter
He says: "Caught this image of the eye of the storm as we flew over Hurricane Earl"

He calls this image River of Ice, saying: "Here is a look at the stunning landscape of the Coastal Mountains, in British Columbia, Canada.
