At Launch Pad 39A at NASA’s Kennedy Space Center in Florida, the crew of space shuttle Endeavour’s STS-130 mission posed for a group portrait in front of Endeavour’s external tank and one of its solid rocket boosters at the conclusion of the Terminal Countdown Demonstration Test, the dress rehearsal for their launch. From left are Robert Behnken, Commander George Zamka, pilot Terry Virts, Kathryn Hire, Nicholas Patrick and Stephen Robinson. The primary payload on STS-130 is the International Space Station’s Node 3, Tranquility, a pressurized module that will provide room for many of the station’s life support systems. Endeavour is set to launch on Feb. 7. Image Credit: NASA/Kim Shiflett
