Spacewalk to reconnect mating adapter after move

Expedition 50 crewmates Shane Kimbrough and Peggy Whitson will work outside the International Space Station on Thursday (March 30) to reconnect a docking port relocated at the orbiting outpost.

The two spacewalkers are scheduled to begin the spacewalk at about 7 a.m. CDT (1200 GMT). The extravehicular activity (EVA) is slated to take about six and a half hours to complete.

Kimbrough and Whitson will run cables and electrical connections to Pressurized Mating Adapter-3 (PMA-3), which was robotically moved on March 26 from the Tranquility module to the Harmony module on the station. PMA-3 provides an interface between the station and visiting vehicles that come to dock.

The PMA will later be outfitted with an international docking adapter (IDA), to be delivered on a SpaceX Dragon cargo spacecraft later this year, so that it can be used by U.S. commercial crew spacecraft.

During Thursday's spacewalk, Kimbrough and Whitson will also install the second of the two upgraded computer relay boxes on the station's truss and install shields and covers on PMA-3 and the now-vacant common berthing mechanism port on Tranquility.

This will be the 199th spacewalk in support of space station assembly and maintenance. It will be Kimbrough's sixth EVA and the eighth by Whitson, who will surpass NASA astronaut Sunita Williams' record for the most spacewalks by a woman.

While working to outfit the open port on Tranquility, the former location of Pressurized Mating Adapter-3, Shane Kimbrough and Peggy Whitson lost one of the axial shields.
"Peggy, I don't have a shield," said Kimbrough.

"What?" replied Whitson.

"Yeah, I don't have a shield," said Kimbrough.

"Where is it? Ah... it is right by the radiator. It is moving station zenith, maybe half a foot a second and it's going, looks like straight zenith from the radiator angle," Whitson said.

"We copy and we see it," radioed Mission Control.

NASA astronaut sets new record for most experienced woman to walk in space

A record-setting NASA astronaut has added two more worldwide credits to her name, becoming the most experienced woman to walk in space.

Peggy Whitson joined her NASA crewmate, Expedition 50 commander Shane Kimbrough, on a spacewalk outside of the International Space Station to run cable connections to a relocated docking port and continue preparations for the future arrival of commercial crew spacecraft.
