New Delhi: NASA astronauts Peggy Whitson and Jack Fischer successfully concluded the historic 200th spacewalk at 1:21 pm EDT.

The spacewalk, which got delayed due to a glitch with the spacesuits, lasted for four hours during which the two astronauts successfully replaced a large avionics box that supplies electricity and data connections to the science experiments.

Additionally, the astronauts also installed a connector that will route data to the Alpha Magnetic Spectrometer, repair insulation at the connecting point of the Japanese robotic arm, and install a protective shield on the Pressurized Mating Adapter-3, NASA reported.

This adapter will host a new international docking port for the arrival of commercial crew spacecraft.

As of now, astronauts who have performed spacewalks have clocked up a total of 1,247 hours and 55 minutes working outside the station during 200 spacewalks in support of assembly and maintenance of the orbiting laboratory.

The spacewalk was the ninth of Whitson's career. She holds the record for most spacewalks by a woman.

As for Fischer, who is also nicknamed '2Fish', this was his first outing.
