How Canada's top astronaut sees the world

Canada's new printed-polymer $5 bill has received the country's highest sendoff, altitude-wise, from International Space Station commander Chris Hadfield. Tuesday's currency-unveiling ceremony in space was just the latest in a series of achievements that have drawn attention to Canada's best-known spaceflier.

Hadfield already has made his mark as a photographer, a musician and composer, and an explainer of spaceflight phenomena ranging from crying to vomiting in zero-G. Some of his latest space shots, including this view of an alligator-like mountain range in Mexico, are featured in our Month in Space Pictures slideshow. To learn more about Hadfield's role in the first outer-space rollout of a bank note, flip over to this Cosmic Log posting.
