Expedition 42 US EVA-31

This is the third and final EVA to prepare the ISS for future commercial visiting vehicles.
Main task is the installation of the Common Communications for Visiting Vehicles antennas (C2V2) and Cable routing to the antennas.
The C2V2 booms and antennas were brought to the ISS aboard Dragon CRS-5.

Astronauts Barry Willmore (EV2) and Terry Virts (EV1) are the space walkers for this final EVA that took place on March 1, 2015. The C2V2 system consists of 2 booms with 4 antennas and 3 specialized reflectors that will require 400 feet of cable that will be routed from the center of the station structure out to the 2 booms.

After both booms were installed, the astronauts proceeded to connect cables to the booms with the antennas. Afterwards, they installed the reflectors on both booms. This concluded US EVA-31.

  2. I can’t wait to see people blasting off from Cape Kennedy again, even if it’s not on a government vehicle.
