ISS023-E-025405 (17 April 2010) --- The underside of space shuttle Discovery is visible in this image photographed by an Expedition 23 crew member on the International Space Station soon after the shuttle and station began their post-undocking relative separation. Undocking of the two spacecraft occurred at 7:52 a.m. (CDT) on April 17, 2010, ending a stay of 10 days, 5 hours and 8 minutes. The visit included three spacewalks and delivery of more than seven tons of equipment and supplies. The recognizable feature on Earth below is the south end of Isla de Providencia, about 150 miles off the coast of Nicaragua near 13.3 degrees north latitude 81.4 degrees west longitude.
