Separation
As the shuttle and the space station began their post-undocking relative separation, Expedition 23 flight engineer Soichi Noguchi photographed the underside of the shuttle over the south end of Isla de Providencia, about 150 miles off the coast of Nicaragua. Undocking of the two spacecraft occurred on April 17, 2010, ending the shuttle's 10-day stay. The visit included three spacewalks and delivery of more than seven tons of equipment and supplies to the station.
