SUBMITTED BY ARTHUR N1ORC - AMSAT A/C #31468 LATEST NEWS Space walkers Perform Electrical Work, Move Carts Mission Specialists Robert Curbeam and Christer Fuglesang took on the roles of electricians and movers during STS-116’s second spacewalk at the International Space Station. During the 5-hour excursion, which ended at 7:41 p.m. EST Thursday, they rearranged the station’s power system from a temporary status to a permanent setup and relocated two equipment carts. To prepare the station for the spacewalkers’ electrical work, flight controllers sent a barrage of commands to power down roughly half of the station’s systems. The spacewalk kicked off at 2:41 p.m., and Curbeam and Fuglesang quickly went to work rewiring two of the station’s four power channels. After they finished the connections, flight controllers began sending commands at 4:45 p.m. to power up the electrical systems in their new configuration. The remaining two channels will be rewired during the mission’s third spacewalk, slated for Saturday. The STS-116 crew is performing the electrical work to bring power generated by the P4 solar arrays on line for use by the station's systems and prepare for more arrays to be added next year. The duo then turned their attention to the relocation of two crew equipment translation aid carts. This cleared the way for the station’s mobile transporter rail car to move down the station's rail system to the S1 truss at a later date in preparation for the STS-117 mission next spring. The final task of the spacewalk was the rerouting of cables on the Z1 truss. Pilot Bill Oefelein coordinated the spacewalk activities. Expedition 14 Flight Engineer Sunita Williams and STS-116 Mission Specialist Joan Higginbotham operated the station’s robotic arm. In other activities, STS-116 and Expedition 14 crew members continued cargo transfers between Space Shuttle Discovery and the station.

STS-116 MCC Status Report #11
by Arthur Rowe 14 Dec '06

14 Dec '06

SUBMITTED BY ARTHUR N1ORC - AMSAT A/C #31468 NASA NEWS 8:30 p.m. CST Thursday, Dec. 14, 2006 Mission Control Center, Houston, Texas 12.14.06 STATUS REPORT: STS-116-11 STS-116 MCC Status Report #11 Two spacewalking electricians completed half of STS-116’s rewiring today, and when flight controllers threw the switch, the lights inside the International Space Station turned on again without a hitch. Mission Specialists Bob Curbeam and Christer Fuglesang began their second spacewalk at 1:41 p.m. CST. Less than two hours later, they had the first half of the station’s permanent power system – channels two and three – up and running, taking advantage of power generated by the solar arrays delivered in September. The second half of the station’s power system – channels one and four – will be reconfigured during the mission’s third spacewalk Saturday. Once that’s done, the station’s power system will be in its assembly complete configuration, ready for the addition of more solar arrays and science modules next year. Before the spacewalkers swapped the cable connections, station flight controllers had to shut down about half of the station’s systems, including some lights, communication gear, ventilation fans and back-up computers. They started the power down just before 2 p.m., and by 3:45 p.m., were powering up main bus switching units for the first time ever and activating power channels two and three. By 4:30 p.m., one of two external thermal control system loops was actively shedding excess heat into space, and the direct current-to-direct current converter units were regulating power voltages. The space walkers headed out the hatch of the Quest airlock this afternoon about 30 minutes ahead of schedule, and made it through their tasks quickly enough to pick up another thirty minutes. They finished at 6:41 p.m., an hour earlier than planned and exactly five hours after they started. Expedition 14 Flight Engineer Suni Williams and STS-116 Mission Specialist Joan Higginbotham operated the station's robotic arm in support of the spacewalk. Before heading back into the station, Curbeam and Fuglesang also relocated two small handcarts that run along rails on the station’s main truss, put a thermal cover on the station’s robotic arm and installed bags of tools for future spacewalkers. Discovery’s crew is scheduled to go to sleep at 1:47 a.m. Friday. Flight Day 7 begins with a wakeup call at 8:47 a.m. The crew will spend the day transferring supplies and equipment from Discovery to the station, participating in a news conference and enjoying some off-duty time. The next STS-116 status report will be issued Friday morning or earlier if events warrant. - end -

STS-116 MCC Status Report #10
by Arthur Rowe 14 Dec '06

14 Dec '06

SUBMITTED BY ARTHUR N1ORC - AMSAT A/C #31468 10:30 a.m. CST Thursday, Dec. 14, 2006 Mission Control Center, Houston, Texas 12.14.06 STATUS REPORT: STS-116-10 STS-116 MCC Status Report #10 The second spacewalk for Discovery's crew members is scheduled for this afternoon. During the spacewalk, set to start about 2:12 p.m. CST, Bob Curbeam and Christer Fuglesang will begin to rewire the station’s power system. Curbeam and Fuglesang spent the night in the station's Quest airlock at a reduced atmospheric pressure of 10.2 psi. The “campout” procedure reduces nitrogen levels in the blood to help avoid decompression sickness as the astronauts go to the even lower pressure of spacesuits. The spacewalk is planned to last about six hours. The two spacewalkers are scheduled to reconfigure two of the station's four power channels, channels 2 and 3, bringing power on line from the new set of solar arrays added to the station in September. The remaining two power channels, 1 and 4, will be reconfigured in a third spacewalk on Saturday. The changes will convert the station power system to a permanent setup, ready for even more arrays and science modules to be added next year. At about 11:22 a.m. CST, station flight controllers will be sending commands that will power down roughly half of the station's systems in preparation for the spacewalkers' rewiring job this afternoon. The result will partially power down some communications systems, lighting, ventilation systems and backup computers, among other systems. Once the spacewalkers have completed the new power connections, flight controllers will power all the equipment and systems back on. As changes are made in the power system, additional cooling systems also will need to be brought online as well. Late last night, half of the new cooling system for the P4 truss was filled with ammonia to be ready to begin circulating today when pumps are activated. During the spacewalk, Curbeam, who will wear a suit with red stripes on the legs, and Fuglesang, who will wear an all-white suit, also will relocate two small handcarts that run along rails on the station’s main truss. Expedition 14 Flight Engineer Suni Williams and Discovery Mission Specialist Joan Higginbotham will operate the station's Canadarm2 robotic arm in support of the spacewalk. Managers and engineers continue to evaluate whether further actions will be taken during STS-116 to complete the retraction of the port P6 truss solar array. The array was retracted almost halfway Wednesday, with only 17 bays of its center mast remaining extended. Fully extended, the mast has 31 bays. The array was retracted sufficiently to allow the new P4 solar arrays to begin rotating last night, an operation that was completed without problems. In their current state, the P6 port array and the P4 arrays have more than 16 feet of clearance from one another. Should they remain as they are, the partially retracted arrays pose no issue for the shuttle's undocking or any planned station activities until a Soyuz relocation flight set for April 2007. A decision on any further action regarding the partially retracted array – including a possible fourth spacewalk during STS-116 for Curbeam and Fuglesang to assist in the retraction -- is not expected before Saturday. Discovery’s crew was awakened at 9:17 a.m. CST today with the song, “Under Pressure,” performed by Queen. It was played for Curbeam. The station crew, Commander Michael Lopez-Alegria and flight engineers Mikhail Tyurin and Williams, woke up a half-hour later. The next STS-116 status report will be issued Thursday evening, or earlier, if events warrant.

STS-116 MCC Status Report #09
by Arthur Rowe 14 Dec '06

14 Dec '06

SUBMITTED BY ARTHUR N1ORC - AMSAT A/C #31468 11:30 p.m. CST Wednesday, Dec. 13, 2006 Mission Control Center, Houston, Texas 12.13.06 STATUS REPORT: STS-116-09 STS-116 MCC Status Report #09 The first phase of the electrical and thermal makeover of the International Space Station was completed tonight as the outpost’s newest solar arrays began rotating to follow the sun and ammonia flowed into the station’s permanent cooling system for the first time. Flight controllers sent commands to enable a large joint to begin rotating around 7 p.m. CST, moving the solar arrays on the P4 truss like a giant paddle wheel to track the sun as the station moves from daylight to darkness in orbit. A few hours later, just before 10 p.m. CST, valves were opened to allow 300 pounds of ammonia to flow into the truss segments of the station and its radiators, the first step toward providing permanent cooling for the avionics and electronics on the complex. Those vital activation tasks occurred after a day-long effort by Discovery’s crew to retract the port array on the P6 solar array truss structure, which was installed six years ago to provide early electrical power for the station. The crew spent six hours today sending as many as 45 commands in a start-stop fashion to retract, then redeploy, then retract the balky Venetian-blind like array panels in an effort to fold them into a narrow blanket box at the base of the array. But guide wires that help fold the arrays flat into the box apparently became snagged with only 17 out of 31 bays of the port array retracted. That was enough, however, to provide enough clearance to enable the new P4 arrays to begin rotating as planned. Mission managers met tonight to discuss various options for completing the P6 array retraction, and decided to press ahead with the second of three scheduled spacewalks Thursday by Bob Curbeam and Christer Fuglesang during which they will rewire the first pair of electrical channels for the permanent power system on the station. Managers will convene over the next few days to determine whether additional spacewalk activity by Discovery’s crew will be scheduled to complete the retraction of the P6 array, although they have concluded that the array is in a safe configuration for the remainder of this mission, Discovery’s undocking next week, and if necessary, for the arrival of a new Russian Progress resupply ship in January should a spacewalking task be added to the Expedition 14 crew following Discovery’s flight. Late tonight, to gather data for a future decision, Mission Control asked Discovery Commander Mark Polansky and Station Commander Mike Lopez-Alegria to consider which flight day would be best for a fourth spacewalk if one is ordered to complete the P6 array retraction. Polansky and Lopez-Alegria asked for more details about what such a spacewalk would entail before offering their thoughts. With the station’s new solar arrays rotating and its permanent cooling system operating as advertised, Discovery’s crew members will begin an eight-hour sleep period at 1:17 a.m. CST and will wake up Thursday at 9:17 a.m. CST to begin preparations for the second spacewalk of the flight. The station crew members will be awakened thirty minutes later. The next STS-116 status report will be issued Thursday morning after crew wakeup, or earlier if events warrant.

SUBMITTED BY ARTHUR N1ORC - AMSAT A/C #31458 *Astronauts Working to Retract Solar Array* S116-E-05789 : port-side P6 solar array Image above: A kink is seen in the port-side P6 solar array during the first attempt to retract it. Image Credit: NASA + View hi-resolution photo <http://www.nasa.gov/images/content/164903main_s116e05789.jpg> (GO TO:http://www.nasa.gov/mission_pages/shuttle/main/index.html) Discovery's crew is still working on the retraction of the port P6 solar arrays that began at 1:28 p.m. EST (6:28 utc). The bays have not been folding properly, and astronauts have been repeatedly retracting and deploying the panels in an attempt to properly align them. The folding of this 115-foot long solar array, which has been unfurled for more than 6 years, will permit the activation of a rotary joint on the P4 truss. The Solar Alpha Rotary Joint, or SARJ, enables the solar arrays on the P4 to follow the sun as the station moves through orbital sunrise and sunset. Activation of the SARJ will follow the retraction. Two more spacewalks during STS-116's stay will rewire and redistribute power on the station. Once automatic sun tracking is confirmed for the new P4 arrays, the stage is set for the second spacewalk, scheduled to begin at 3:12 p.m.(8:12 UTC) Thursday. Mission Specialists Bob Curbeam and Christer Fuglesang, who conducted the mission’s first spacewalk, will perform Thursday’s excursion. Curbeam and Fuglesang will again "campout" in the station’s airlock to prepare for the spacewalk. During the overnight “campout” the pressure will be lowered in the airlock to the pressure normally found on Earth 10,000 feet above sea level. The procedure protects against decompression sickness as Curbeam and Fuglesang go to the even lower pressure of spacesuits on Thursday. In other activities today, crewmembers will field questions from the CBS Radio Network, the Fox Radio Network and SPACE.com at 8:07 p.m. For the latest news and information on the International Space Station and the Expedition 14 crew, please visit the main station page. + Read more <http://www.nasa.gov/station>

SUBMITTED BY ARTHUR N1ORC - AMSAT A/C #31468 *P6 Solar Array Wing Retracting* retracted. Image Credit: NASA TV The first step in STS-116’s challenging job of rerouting power aboard the International Space Station is under way as the left wing of the solar array on the station's P6 truss has begun to slowly retract and fold up. The retraction began at 1:28 p.m. EST. The folding of this 115-foot long solar array, which has been unfurled for more than 6 years, will permit the activation of a rotary joint on the P4 truss. The Solar Alpha Rotary Joint, or SARJ, enables the solar arrays on the P4 to follow the sun as the station moves through orbital sunrise and sunset. Activation of the SARJ is set for 2:57 p.m. Two more spacewalks during STS-116’s stay will rewire and redistribute power on the station. Once automatic sun tracking is confirmed for the new P4 arrays, the stage is set for the second spacewalk, scheduled to begin at 3:12 p.m. Thursday. Mission Specialists Bob Curbeam and Christer Fuglesang, who conducted the mission’s first spacewalk, will perform Thursday’s excursion. Curbeam and Fuglesang will again “campout” in the station’s airlock to prepare for the spacewalk.

STS-116 MCC Status Report #07
by Arthur Rowe 13 Dec '06

13 Dec '06

SUBMITTED BY ARTHUR N1ORC - AMSAT A/C #31468 STATUS REPORT: STS-116-07 STS-116 MCC Status Report #07 The International Space Station is now two tons heavier, with the installation today of its newest truss segment during the flight’s first spacewalk. Mission Specialists Bob Curbeam and Christer Fuglesang ventured outside the station to attach the P5 segment of the station’s truss and replace a failed camera needed to support future assembly tasks. They also were able to fit in some extra tasks that will save future spacewalkers time, including plugging the new segment into the existing truss, removing the locks that held it steady during launch and opening a latch that will allow the P6 segment to be attached when it is moved from its current, temporary location to its permanent place at the end of the port truss. The spacewalk began at 2:31 p.m. CST, and Curbeam and Fuglesang were back inside by 9:07 p.m. The truss was officially attached at 4:45 p.m., and installation was complete by 5:21 p.m. Total duration of the spacewalk was 6 hours, 36 minutes. Upon their return to the Quest airlock at the end of the spacewalk, Curbeam took a moment to congratulate Nobel Prize winners, including Dr. John C. Mather, a Goddard Space Flight Center scientist honored for his work on the big-bang theory. With the new port truss section in place, the crew is ready to move on to the second phase of the mission – rewiring the station. That work will begin Wednesday when the port solar array on truss segment P6 is folded up, allowing the P4 solar arrays delivered by the STS-115 crew to rotate and track the sun. Once that’s done, Curbeam and Fuglesang will head outside again Thursday to begin reconfiguring the external wiring so that power from the new solar arrays delivered in September can be used. Meanwhile, after taking a close look at imagery gathered on the first three days of the flight, mission managers determined that the shuttle’s heat shield can support a safe return to Earth. They also decided a more detailed inspection that had been scheduled for tomorrow will not be necessary. Space Shuttle Discovery’s seven astronauts woke at 9:47 a.m. this morning to the song “Waterloo” by Swedish group Abba in honor of Fuglesang, who is from Sweden. “Nice music this morning,” Fuglesang said from the Quest airlock, where he spent the night preparing for the spacewalk with Curbeam. The crew is scheduled to go to sleep at 1:17 a.m. Wednesday, after moving the space station arm into a position that will provide a good view of the P6 solar array retraction. The shuttle crew will start flight day four at 9:17 a.m. on Wednesday. The station crew will get an extra 40 minutes of sleep, awakening at 9:47 a.m. The next STS-116 status report will be issued Wednesday morning or earlier if events warr
