Do we know yet which EMUs will be used for the EVA?
Our first spacewalk is now on Saturday, to allow some time for our procedures and safing steps to mature a bit. The airlock, and our equipment are ready. We're anxious to get started and get the Space Station back up and running. Here is a glimpse into the airlock with our spacesuits staged. This won't be easy, but our team is ready…

Just wondering – I'd like to look over shuttle EVA √lists if available and haven't gotten my hands on one of these before.

The Darpa International Space Station Spheres Integrated Research Experiments (Inspire) program represents an initial step in that direction. With the ISS acting as a "satellite wind tunnel", the goal is to enable rapid, iterative testing of space systems while providing students with an opportunity to perform meaningful space experiments.Inspire will upgrade the Spheres microsatellites already onboard the ISS. Designed and prototyped by MIT students, the three microsatellites are used for formation-flying algorithm research. They have been on the ISS since 2006 and are operated by astronauts in their free time, for about 12 experiments a year. Now in the Kibo module, the battery-powered microsatellites use cold-gas thrusters to maneuver and an ultrasonic "GPS simulation" to navigate.The Inspire program has four elements: electromagnetic formation flying; vision-based relative navigation; a design study for "Exo-Spheres" microsatellites that could fly outside the ISS; and a design challenge to involve high school students in the development of algorithms for the Spheres spacecraft.Two of the Spheres satellites will be equipped with steerable magnetic coils that will enable them to maneuver relative to each other by generating forces and torques via electromagnetic coupling. In a cluster of satellites, such as Darpa's System F6, this would allow a formation of modules to maneuver in space by wirelessly coupling to one thruster-equipped spacecraft.The vision-based relative navigation project will involve two microsatellites circumnavigating the third and using sensors to build a 3D model of the target Sphere. This will enable the two Spheres to navigate relative to the third by visual reference—matching images to the model—and allow formation flight in the absence of precise GPS positioning.The Exo-Spheres design study will be an undergraduate project to prototype the next-generation Spheres testbed, which would be able operate for short periods outside the ISS. "They would throw them out of the Kibo airlock, perform experiments and use the small Japanese robotic arm to retrieve them", says Paul Eremenko, a Darpa program manager.
After the ETCS failure, I recall it being said that engineers weren't sure if the PM itself was actually the culprit. Did NASA ever determine root cause or were they forced to go forward with "most likely"?
