6/13/2002 17:48:41The third and final scheduled spacewalk of the STS-111 mission concluded at 5:33 p.m. Central time. Astronauts Franklin Chang-Diaz and Philippe Perrin spent 7 hours 17 minutes (7 hours, 16 minutes, 37 seconds) working outside the confines of Endeavour and the International Space Station today.

During today's spacewalk, the 41st in support of space station assembly and maintenance, the spacewalkers successfully removed a failed wrist roll joint from the station's robotic arm, Canadarm2, and installed a new joint in its place.

Flight controllers verified the success of the replacement and checked out the arm's operation.

Over the course of the three spacewalks conducted by Chang-Diaz and Perrin during this mission, they spent a total of 19 hours and 31 minutes working in the vacuum of space.

The crews are scheduled to go to sleep just before 8 p.m. central time and will awaken just before 4 a.m. Friday.

6/13/2002 15:45:40STS-111 spacewalkers Franklin Chang-Diaz and Philippe Perrin have successfully installed a new wrist roll joint on the space station's robotic arm. Flight controllers completed initial tests of the new joint at 3:39 p.m. CDT and pronounced it alive and well.


6/13/2002 15:11:3Spacewalkers Franklin Chang-Diaz and Philippe Perrin successfully installed a new wrist roll joint on the space station's robotic arm about 2 p.m. central time today.

Approximately 45 minutes later, the arm's latching end effector was installed and by 3 p.m. flight controllers begin applying power to Canadarm 2 to verify the health of the station's newly refurbished arm.
6/13/2002 13:14:18Slightly less than three hours into today's planned seven-hour spacewalk, Franklin Chang-Diaz unbolted the latching end effector - or hand - of the Station's robotic arm at 12:54 p.m. central time.

Chang-Diaz handed off the end effector to fellow spacewalker Philippe Perrin who maneuvered it into its temporary storage location eight minutes later.

The duo will now turn its attention to removing the failed wrist roll joint on Canadarm 2, stowing it in Endeavour's payload bay, and then unstowing and installing the new wrist roll joint. Once the new joint is installed, the end effector will be retrieved from its temporary storage location and reattached to the station's robotic arm.

6/13/2002 10:16:47Endeavour astronauts Franklin Chang-Diaz and Philippe Perrin placed their spacesuits on internal battery power at 10:16 a.m. Central time, marking the start of the third and final spacewalk of the STS-111 mission.

Chang-Diaz and Perrin will spend around 7 hours outside the Endeavour/International Space Station complex replacing a faulty wrist roll joint near the hand, or end effector of the seven-jointed Canadarm2 robotic arm on the ISS.

The wrist component has experienced some electrical problems in one of two redundant power and data channels, and the spacewalk repair effort today will restore the critical robotic arm to full functionality.

6/9/2002 17:51:59The 39th spacewalk dedicated to assembly and maintenance of the International Space Station concluded at 5:41 p.m. central time today.

Lasting 7 hours 14 minutes, the spacewalk saw Franklin Chang-Diaz and Philippe Perrin prepare the Mobile Base System for a Monday installation on the Mobile Transporter railcar on the International Space Station, and the attachment of a series of debris shielding panels to the Zvezda module for installation during a later spacewalk.

Following a busy and successful day in space, the 10 astronauts and cosmonauts will relax briefly before going to bed at 8:23 p.m. central time.
6/9/2002 16:41:41A little more than six hours into today's spacewalk, Franklin Chang-Diaz and Philippe Perrin are completing their final scheduled task before beginning to clean up Endeavour's payload bay and reenter the Space Station.

Today's spacewalk began at 10:27 a.m. central time. The primary tasks for Chang-Diaz and Perrin were to prepare the station's Mobile Base System for installation on to the station's Mobile Transporter railcar on Monday, and to attach a package of shielding panels that will be installed on the Zvezda module during a future spacewalk.

The space station's robotic arm will be used to lift the Mobile Base System out of Endeavour's payload bay and park it overnight to ensure that temperatues on the Mobile Base System and Mobile Transporter are similar prior to installation tomorrow.

Once the Mobile Base System is lifted out of the payload bay, Chang-Diaz and Perrin will begin cleaning up in anticipation of concluding today's spacewalk activities.

6/9/2002 13:18:37Two hours into their first spacewalk, Endeavour astronauts Franklin Chang-Diaz and Philippe Perrin successfully installed a power and data grapple fixture to the P6 Truss on the International Space Station which houses the huge U.S. solar arrays for the complex.

The grapple fixture will be needed next year so the station's robotic arm can move the truss outboard on the complex as additional truss segments are added.

Working close to the timeline, Chang-Diaz and Perrin have moved onto the transfer of a series of micrometeoroid debris shields from Endeavour's payload bay to the Russian segment of the ISS. Those shields will be installed by Expedition Five Commander Valery Korzun and Flight Engineer Peggy Whitson during a spacewalk in late July.

All is proceeding smoothly with the spacewalk, which is the 39th excursion in support of the assembly and maintenance of the ISS.

6/9/2002 10:36:7Endeavour Astronauts Franklin Chang-Diaz and Philippe Perrin placed their spacesuits on internal battery power today at 10:27 a.m. Central time to begin a planned six-hour spacewalk designed to prepare the Mobile Base System for its installation on the International Space Station tomorrow morning.

Chang-Diaz and Perrin are now conducting the 39th spacewalk in support of ISS assembly and maintenance, the 14th staged out of the station itself and the 7th conducted out of the Quest Airlock.

Chang-Diaz and Perrin will remove thermal blankets protecting the Mobile Base System in Endeavourt's payload bay in advance of Expedition Five Flight Engineer Peggy Whitson and former Station crewmember Carl Walz grappling the MBS later today with the station's robotic arm.

The MBS will be hoisted out of the bay and positioned just above the Mobile Transporter railcar on the Station's S-Zero Truss for installation tomorrow.

The Mobile Base System will serve as the platform upon which the Station's robotic arm will be attached to move up and down the length of the complex for future assembly tasks.

Chang-Diaz and Perrin will also move micrometeroid debris shields from the payload bay to the Russian segment of the ISS for later installation on the Zvezda Service Module and attach a grapple fixture to the ISS P6 Truss for its future relocation on one of the Station's outboard trusses.

6/9/2002 4:37:17The early morning entry is the same as STS-111 Mission Control Status report #9.
