Students Ask an Astronaut

On her third mission to space, Wilson in April traveled to the International Space Station on Discovery to deliver more than 27,000 pounds of hardware, supplies, experiments and equipment, including a tank full of ammonia coolant that required three spacewalks and robotics to install, new crew sleeping quarters and experiment racks, according to NASA.

"During the mission Wilson was primarily responsible for robotics and EVA support using the Space Station Robotic Arm. On the return journey the MPLM (Leonardo Multi-Purpose Logistics Module) inside Discovery’s payload bay was packed with over 6,000 pounds of hardware, science results and used supplies. The STS-131 mission was accomplished in 15 days, 2 hours, 47 minutes, 10 seconds, and traveled 6,232,235 statute miles in 238 orbits."
