Space walkers come back after detecting and repairing the particle detector

NASA astronaut Andrew Morgan and European Space Agency astronaut Luca Parmitano have come back after completing their third complex spacewalks. The two astronauts were sent to space to fix the experimental physics device designed to detect antimatter in cosmic rays. 

According to a Twitter update, Morgan and Parmitano had completed all the primary tasks in the first few hours required for the spacewalk and started working on further requirements. Further reports confirmed that the Duo switched on to their spacesuits to battery power at around 6:31 AM on Monday. 

The reports presented by NASA confirm that the astronauts were given seven and a half hours to fix the problem at the space station. But, the two managed to finish their work quite early at 12:33 PM, that is, with six hours and two minutes of the spacewalk. 

The duo was successful in installing a cooling new system for the Alpha Magnetic Spectrometer, as said by the ISS on Twitter.
