NASA and ESA have concluded a series of four spacewalks to repair the Station’s Alpha Magnetic Spectrometer experiment. NASA astronaut Drew Morgan and European Space Agency (ESA) astronaut Luca Parmitano completed the series with the AMS deemed to be in good health.
Never designed to be serviceable after it was installed outside the Station in May 2011, the Alpha Magnetic Spectrometer (AMS) required some unique thinking in order to bring it back to full operational capacity.
