Finished set up of the 4B modification kit. The astronauts will enterprise outdoors and take away H fixtures on the 3B mass canister on the S6 Truss, set up the telescopic booms on 2B mass canister which were left undone on the previous spacewalk, exchange Camera 9 and bring it back inside, install a router on the Camera 9 group for vaporverkauf future spacewalks, change a light, and set up a DC to DC Converter Unit jumper cable.
The final tasks to relocate the Period management panel, set the arm back to “grapple mode”, and vapehome remove the launch rings from the wrist of Period will likely be moved to the subsequent spacewalk. Moghbeli and O’Hara ventured outside and eliminated an H fixture from the 3B mass canister on the S4 truss in preparation for the arrival of the struts and the IROSA solar arrays in 2025. In addition they changed a damaged Trundle Bearing under Cover 2 which had been giving them hassle previously and greased the tracks before the new Trundle Bearing was installed on the port SARJ, secured a cable on Camera 8 which was shorting out a mild used for dockings, vapemode and launched wedge clamps on the SASA antenna.
O’Hara was not secured properly throughout the elimination and needed to be assisted by Moghbeli to get the cowl stowed. Parmitano and Morgan lower fluid traces and put in a vent on the AMS Experiment to prep the previous cooling pump for elimination on the third spacewalk. The 2 spacewalkers accomplished all the duty and at 17:30 hours Luca Parmitano opened a valve to start the movement of CO2 gasoline to AMS and contacted CERN to turn the experiment on.
As part of a get-ahead task, they inspected an ammonia vent line on Unity and inspected a foot restraint located near the Z1 Radio Antenna. The cosmonauts ventured exterior and vaporizershake installed a mini radar experiment on Nauka, launched a CubeSat which can check photo voltaic sails, and photographed the RTOd radiator vaporizershake and closed valves to isolate the radiator and ezigaretterabatt vented residual coolant so plans may be accomplished to fix a leaking cooling line that delayed two US spacewalks.
They installed the Era control panel at a new basepoint, eliminated launch rings and covers from Era, returned the arm to “grapple mode”, performed take a look at on Period, and installed two payload adapters on Nauka.
On the conclusion of the spacewalk the two batteries had been turned on and the bottom reported that they were working and that there have been no signs of a short. Williams and Wilmore ventured out, retrieved the SASA Antenna and introduced it again inside while additionally accumulating samples from the station’s hull to look for indicators of microbial progress that may very well be present on the modules both after launch or being uncovered to area.
