Once Alexander Gerst is moved into position on the Station’s robotic arm – controlled by NASA astronaut Butch Wilmore from inside – Reid and Alexander will work together to install the pump module. The module will be installed on the External Stowage Platform near the US Destiny lab where it will not get in the way while being accessible for future use.

First the module needs to be made ready by removing the AGB, an adapter that held it at its previous position. The AGB is no longer needed so is removed. Four bolts are screwed in using the spacewalk drill.

With that done they need to clean up the AGB that is no longer needed. They have almost half an hour planned for this task. Afterwards Reid will stick around to protect the module with insulation while Alexander will be transported with the robotic arm again to his next task: replacing a failed light.
