— Mission Summary —

NASA astronauts Shane Kimbrough and Peggy Whitson; Russian cosmonauts Sergey Ryzhikov, Andrei Borisenko and Oleg Novitskiy; and European Space Agency astronaut Thomas Pesquet worked on about 200 experiments including a study on how lighting can change the health and well-being of station crew members, experiments on the effect of microgravity on the genetic properties of space-grown plants and how zero-g can impact tissue regeneration in humans. Four spacewalks were performed and many visiting vehicles came and went over 5.5 months.

Derek Richardson

I am a space geek who loves to write about space.

My passion for space ignited when I watched space shuttle Discovery leap to space on October 29, 1998. Today, this fervor has accelerated toward orbit and shows no signs of slowing down. After dabbling in math and engineering courses in college, I soon realized that my true calling was communicating to others about space exploration and spreading that passion.

Currently, I am a senior at Washburn University studying Mass Media with an emphasis in contemporary journalism. In addition to running Orbital Velocity, I write for the Washburn Review and am the Managing Editor for SpaceFlight Insider.
