Today NASA Astronaut Reid Wiseman and ESA Astronaut Alexander Gerst steps outside the International Space Station for a 6h 13m spacewalk.
This was the first spacewalk for each of the Astronauts and was completed successfully. This was the 182nd spacewalk in support of the ISS for a total of 47d 14h 15m,
During the spacewalk they were able to complete the following tasks.
The first task for Wiseman and Gerst was relocating a failed cooling pump to External Stowage Platform-2 (ESP-2) just outside the Quest airlock. It was temporarily stowed on the station’s truss by Expedition 38 spacewalkers Mike Hopkins and Rick Mastracchio on Dec. 21 after they replaced the failed pump with a spare.
When they completed the pump module stowage work, the duo stowed adjustable grapple bars on ESP-2. Wiseman cleaned up the work area around the pump module.
Gerst went on to replace a light on an External Television Camera Group (ETVCG) outside Destiny.
The next task was the installation of a Mobile Transporter Relay Assembly (MTRA) on to the S0 truss right above the Destiny laboratory. The MTRA adds the capability to provide “keep-alive” power to the Mobile Servicing System when the Mobile Transporter is moving between worksites.
The Mobile Transporter can move supplies, gear and the Canadarm2 on rails along the Integrated Truss Structure, the station’s backbone. The Mobile Servicing System, which includes the transporter and Canadarm2, plays a key role in station maintenance tasks.
During the repress of the airlock, confirmation that the work on the Mobile Service System had been successfully tested was received.
The newly installed MTRA has passed its initial test – @astro_reid & @Astro_Alex will be happy to hear that. #ISS
