  A favorite activity of astronauts and cosmonauts aboard the International Space Station is looking at the city lights below when the Station crosses the Earth's dark side. The lights outline the densest population centers and coastlines, and suggest cultural patterns. Taking these low-light images using the equipment on board the Station has been challenging to the crew members because of the long exposure times required. Astronaut Don Pettit, who leaves the station for Earth today (May 3, 2003), has pioneered an approach using a home-made tracking system to track the ground as it moves relative to the Station, allowing him to acquire long-exposure images under low light conditions. Don's ingenious "Barn-Door Tracker" is a camera mount with a rigged with a hand drill to create a motion tracking system.

This image shows the sprawling urban footprint of Sao Paulo, Brazil, South America's largest city with roughly 17 million people. The different colors (pink, white, and gray) define different types and generations of streetlights. The port of Santos, on the right side of the photograph, is also well defined by lights.
