On March 28, 2011 at 15:45 UTC Japan's HTV-2 Konotori unmanned cargo spacecraft undocked from the International Space Station.
American astronaut Coleman and Italian flight-engineer Nespoli grappled the HTV with the station’s robot arm and methodically pulled the spacecraftfrom the space station's Harmony module. Coleman and Nespoli were at the controls of the robot arm inside the seven-window cupola module.
The space station crew issued a retreat command a few minutes later for the HTV to fly away from the space station. Two separation engine burns guided the ship on a safe trajectory departing the complex.
