External Tank 94

External Tank 94
External Tank 94 ET-94, the last remaining space shuttle external fuel tank, sits outside NASA's Michoud Assembly Facility in New Orleans, Louisiana. Following the Columbia accident, Engineers ran tests on the tank to learn how foam shedding could damage the orbiter during ascent. The tank will now be mated to space shuttle Endeavour for display at the California Science Center in Los Angeles, California. Jason Davis / The Planetary Society
