Shuttle Astronauts Set for Reboost, Hour Off
21 November 2008 10:33 a.m. EST

Astronauts aboard NASA?s space shuttle Endeavour areback to work today hauling new supplies into the International Space Stationand tacklingglitches with the space station?s new Water Recovery System that turnsurine into water.

The urine processor was activatedfor about 2 hours this morning before it shut itself down following otherglitches late Thursday. Meanwhile, Endeavour?s crew is due to take about anhour off today and fire their spacecraft?s engine to boost the space stationinto a higher orbit.

Look for the space station reboostto take place at about 12:10 p.m. EST (1710 GMT) and astronauts to speak withreporters around 3:05 p.m. EST (2005 GMT).

Mission Control roused the astronauts at 9:05 a.m.EST (1405 GMT) with a song for lead spacewalker Heide Stefanyshyn-Piper called ?Unharness Your Horses.?

?I?dlike to thank my family and all of my friends for that lively song for wakingup to get us ready for another fun day in orbit today,? Stefanyshyn-Piper said.

Today is Flight Day 8 of Endeavour?s planned 15-daymission to the space station.

Second Spacewalk Concludes for Endeavour Crew
20 November 2008 7:52 p.m. EST

Endeavour astronauts Heide Stefanyshyn-Piper andShane Kimbrough have begun repressurizing the Questairlock aboard the International Space Station, officially ending today?sspacewalk.

Total spacewalking time: 6 hours, 45 minutes

The astronauts began the spacewalk at 12:58 p.m. EST(1758 GMT). During the work, they moved a pair of equipment carts andlubricated the station?s Canadian-built robotic arm. They inspected a blemishedcable and continued the arduous cleaning and lubricating of the space station?sbalky solar array gear.

A wrap up of today?s spacwalkwill be posted to SPACE.com?s homepage shortly.

Spacewalker Heads Back to Station Airlock
20 November 2008 7:33 p.m. EST

SpacewalkerShane Kimbrough is returning to the airlock aboard the International SpaceStation before crewmate Heide Stefanyshyn-Piper due to rising levels of carbondioxide in his spacesuit. Kimbrough?s levels were higher thanStefanyshyn-Piper, so Mission Control ordered him back to the station?s Questairlock.

Stefanyshyn-Piperis also now headed back to the airlock as they spacewalkers prepare to concludetoday?s work outside the station.

20 November 2008 3:02 p.m. EST

Aftermoving a pair of equipment carts outside the International Space Station, spacewalkerShane Kimbrough will now give the orbiting laboratory?s Canadian-builtrobotic arm a tune-up of sorts.

He?lluse some space grease to lubricate the sensitive snare at the tip of the arm,which is used to grapple station components, the outpost?s hull and eventuallygrab spacecraft and guide them to open docking ports. Fellow spacewalker HeideStefanyshyn-Piper is beginning work to clean and lubricate the station?s balkystarboard solar array gear.

SpacewalkersHeide Stefanyshyn-Piper and Shane Kimbrough are movinga pair of equipment carts from the right side of the International SpaceStation?s railcar-like Mobile Transporter to its left, or port, side.

Themove is needed to prepare the station for a planned February shuttle missionthat will deliver new solar arrays for the starboard side. In order to installthe new solar wings, the railcar needs a clear path to the rightmost edge ofthe orbital lab.

Thework is going smoothly, with the astronauts working about 20 minutes ahead ofschedule.

SpacewalkersHeide Stefanyshyn-Piper and Shane Kimbrough arehard at work outside the International Space Station, where they?re gear upto move two pushcarts on the outpost?s backbone-like main truss.

Stefanyshyn-Piperinspected an odd blemish on a cable that transfers power and data to and fromthe station?s railcar-like Mobile Transporter.

?Itlooks like a black mark,? she told Mission Control, which had spotted theblemish before and wanted to know what it was.

Kimbrough,meanwhile, is getting ready to climb aboard the station?s Canadarm2 roboticarm, which is being flown by astronauts Sandra Magnus and Don Pettit inside theorbiting laboratory. Shuttle Endeavour pilot Eric Boe is choreographing today?sspacewalk from inside the orbiter.

Thespacewalk is the fourth for Stefanyshyn-Piper, who can be identified by the redstripe on her NASA spacesuit and the number 16 in helmet camera views hereon NASA TV.

Itis the first spacewalk for Kimbrough, who bears a dashed stripe on hisspacesuit and the number 18 on his helmet cam views.

Astronauts Wake to False Smoke Alarm
19 November 2008 9:22 a.m. EST

Astronautsaboard the International Space Station and shuttle Endeavour are wide awake, ifthey weren?t before, after a false smoke alarm set off an alert inside thestation?s Russian service module.

?Yeah,we had a nice wake up call,? station commander MichaelFincke told Mission Control.

Thesmoke alarm came just after Mission Control woke Endeavour?s shuttle crew for aday of orbitalplumbing work inside the space station. Station flight engineer Yury Lonchakov conferred with Russia?sMission Control in Korolev, just outside Moscow toconfirm it was a false alarm.

?Ichecked everything for smoke, no smoke,? he said.

NASAMission Control roused Endeavour?s crew at 8:55 a.m. EST (1355 GMT) with thesong ?Fanfare for the Common Man? by Aaron Copeland. The tune was selected forshuttle pilot Eric Boe, who thanked his family for the song.

?We?reready to continue making extremehome improvements,? Boe said.

Shuttle Endeavour?s Heat Shield Gets Clean Bill of Health
19 November 2008 12:02 a.m. EST

Thevital heat shield on NASA?s space shuttle Endeavour is clear of any concernsfor its planned landing later this month, Mission Control radioed the orbiter?sseven-astronaut crew. Analysts have reviewed photos and data from twoinspections of Endeavour?s hull and found no areas of concern.

Thenews, while expected, received a glowing review from Endeavour skipper ChrisFerguson:

?That is absolutely fantastic news,?Ferguson told NASA?s shuttle Mission Control in Houston. ?I know it weighs onall of us a little bit until the final word comes but that is just very welcomenews. I think we?ll all rest a little bit easier tonight.?

Endeavour astronauts will stillperform the now standard late inspection of Endeavour?s heat shield to hunt fornew damage caused after the previous two surveys. NASA has kept close watch onshuttle heat shield health since wing damage led to the loss of the shuttleColumbia and its astronaut crew in 2003.

Thefirst spacewalk of NASA?s STS-126 mission to the International Space Station isover as spacewalkers Heide Stefanyshyn-Piper and Steve Bowen have begun repressurizing the outpost?s Quest airlock. The spacewalkended at 8:01 p.m. EST (0101 Nov. 19 GMT).

Totalspacewalking time: 6 hours, 52 minutes.

Thespacewalkers cleaned and lubricated part of a massive space station gear,retrieved an empty nitrogen tank installed a spare part for the station?scooling system and performed other maintenance.

Theyalso lost an equipment bag that drifted off into space while Stefanyshyn-Piperwas cleaning up a grease gun leak.

?In spite of our little hiccup, onemajor hiccup there, I think we did a pretty good job today,? Stefanyshyn-Pipersaid at the end.

?Youwere all champs,? spacecraft communicator Mark Vander Heiadded. ?You rolled with the punches and made it all happen.?

Asidefrom a lost tool bag and exploded grease gun, today?s first foray into cleaningand greasing a massive solar array gear outside the International Space Stationby spacewalkers Heide Stefanyshyn-Piper and Steve Bowen has gone well.

Asthe spacewalk nears the six-hour mark, Bowen has completed his gear cleaningwork and is packing up his tools. Stefanyshyn-Piper, meanwhile, is continuingher clean up work on a different part of the gear.

Today?sspacewalk began at 1:09 p.m. EST (1809 GMT) and was slated to run about 6 1/2hours.
