The mission continues to progress through the timeline, with its mix of transfers, robotics and spacewalks \u2013 the latter proving to be the only element that is currently behind its pre-planned schedule.<\/p>\n<\/p>\n

Flight Day 9 concentrated on the robotics side of the mission, with the robotic arm on the Kibo module put to good use to transfer three science payloads on to the JEF (Japanese Exposed Facility).<\/p>\n
Those payloads \u2013 which arrived on Station via Endeavour \u2013 are the (Monitor of All-sky X-ray Image (MAXI), Space Environment Data Acquisition equipment \u2013 Attached Payload, or SEDA-AP and Interorbit Communication System (ICS), which were moved from the Japanese Exposed Section, ahead of being stowed back on Endeavour at the weekend for a return back to Earth.<\/p>\n
Flight Day 10 concentrated on EVA-4, conducted by Cassidy and Marshburn, focusing soley on the priority task of replacing the four remaining batteries in the Port 6 truss integrated electronics assembly.<\/p>\n

Friday\u2019s spacewalk was literally all about finishing the P6 battery task, following the termination of EVA-3 slightly earlier than planned due to higher than nominal concentrations of CO2 building up in Cassidy\u2019s EMU.<\/p>\n
Cassidy, a Navy SEAL, was jokingly tagged as \u201cbasically Chuck Norris minus the restrictions of gravity,\u201d in a joke flight rule presentation sent up to the crew, and ironically it was his impressive military training background that probably caused the CO2 spikes, as he sped out of the Quest Airlock \u2013 showing no fear and a bit too much excitement \u2013 on his debut spacewalk.<\/p>\n
While the LiOH canister \u2013 which aids the removal of CO2 concentrations from the EMU \u2013 was changed out and will be inspected back on the ground, Cassidy was told to take EVA-4 at a more relaxed pace. He still suffered some elevated CO2 levels during the spacewalk.<\/p>\n
Given only two batteries were installed on to P6 during EVA-3 \u2013 when four out of a total of six were scheduled \u2013 it was hoped EVA-4 would complete the priority task \u2013 and that was officially the case after around six hours duration into the spacewalk.<\/p>\n
The status heading into EVA-4 saw the P6 with two new batteries already installed, with a third safely stowed as EVA-3 was called to an end. Three of the old P6 batteries were also successfully removed and stowed in their temporary home on External Stowage Platform 3 (ESP3), meaning the task is about half way complete by the time the EVA-4 spacewalkers arrive at the worksite.<\/p>\n
![\"L3\"](\"https:\/\/www.nasaspaceflight.com\/wp-content\/uploads\/2009\/07\/L3.jpg\" "\\"L3\\"")
The new batteries were transferred from the ICC-VLD (Integrated Cargo Carrier \u2013 Vertical Lightweight Deployable), which is grappled by the SSRMS (Space Station Remote Manipulator System) \u201cCanadarm2\u201d.<\/p>\n
\u201cThe new batteries are lettered A-F. The old batteries on the Integrated Electronics Assembly (IEA) are numbered 1-6,\u201d noted the Flight Plan Walkthrough on the Battery R&R procedure.<\/p>\n
\u201cBattery 1 was removed from the IEA and temp stowed in order to make room for the first new battery. Battery A was then removed from the ICC and installed into location 1 on the IEA. Battery 4 was removed from the IEA and installed onto the A location on the ICC.<\/p>\n
\u201cBattery B was then removed from the ICC and installed into location 4 on the IEA. Battery 3 was removed from the IEA and installed onto the B location on the ICC.\u201d<\/p>\n
EVA-4 picked up with the installation of Battery C into the IEA. It took around one hour before the spacewalkers are in the correct configuration to restart the R&R tasks.<\/p>\n
\u201cBattery 2 will be removed from the IEA and installed into the C location on the ICC. Battery D will be removed from the ICC and installed into location 2 on the IEA. Battery 1, which was temp stowed, will now be installed onto the D location on the ICC.<\/p>\n
\u201cDuring the Battery R&R, the SARJ (Solar Alpha Rotary Joints) will be prohibited from rotating. Post EVA, the SSRMS will maneuver to a SARJ clear position, to allow the SARJ to rotate again.\u201d<\/p>\n
The successful completion provides the STS-127 crew with the ability to utilize EVA-5 \u2013 which will take place on Monday \u2013 to its maximum capability.<\/p>\n
No major issues are being worked on Endeavour, with items relating to an OCA Router Harddrive failure, and a Left OMS Engine GN2 Leak all holding no mission impact for STS-127.<\/p>\n

The latest issue reported by the Mission Evaluation Room (MER) relates to Fuel Cell 3. Again, no mission impact is expected.<\/p>\n
\u201cFuel Cell 3 sustaining heater came on for 21 minutes should be 3 to 4 minutes,\u201d noted the latest addition to the MER \u201cfunny\u201d (denoting small issues) list. \u201cMOD EGIL (Electrical Generation and Illumination Engineer) broke the B to C bus tie which removes the direct connection to SSPTS (Station- to-Shuttle Power Transfer System).<\/p>\n
\u201cVehicle is in safe and stable configuration. EGIL is currently assessing options on forward plan.\u201d<\/p>\n
Flight Day 11 is a planned Crew Off Duty Day, although some robotics is planned with Canadarm2\u2019s grapple and handoff of Japanese Exposed Section to Shuttle robotic arm for berthing in Endeavour\u2019s Payload Bay.<\/p>\n
Transfer of equipment and payloads from Endeavour to Station will continue, as over 2,000lbs of upmass is added to the ISS\u2019 supplies.<\/p>\n
More will follow during the EVA. For live up-to-the-second updates, refer to the live coverage link above.<\/p>\n
