HOUSTON -- The astronaut crews of NASA'sshuttle Discovery and the International SpaceStation (ISS) lauded their joint mission as it passed the halfway markFriday.
"It hasbeen pretty fantastic," Discovery's STS-116commander Mark Polansky told reporters, adding that watching the five first-timespaceflyers on his crew has been a special treat. "They're just doing great."

After twospacewalks, the joint crews have installeda new piece of the station's main truss and rewiredhalf of its power grid. The other half of the rewiring job is on tap for a thirdplanned spacewalk on Saturday, and ISS flight controllers are discussing a possiblefourthexcursion to completely tuck away a half-furledsolar array before Discovery's crew heads home.
"Of course,we're excited about the possibility of helping out and helping make the houseup here a little bit better by fixing that solar array if we can," STS-116mission specialist RobertCurbeam, a veteran spacewalker, said. NASA hopes to avoid a fourthspacewalk and stowthe array remotely if possible.
One shuttleastronaut, SunitaWilliams, will remain aboard the ISS when Discovery undocks from the ISS.
"It's justa nice place to live," said Williams, who joined the Expedition 14 crew afterarriving aboard Discovery. "My new home is beautiful; it's a little bit crowdedright now with all the stuff we've brought over from SPACEHAB and my shuttle compadreshere."
Williams is relieving European Space Agency astronaut ThomasReiter, who has lived aboard the ISS since July and will return to Earthwith Discovery's crew next week.
"Well itcertainly kind of a bittersweet moment, I should say," Reiter said of leavingthe ISS. "But having been here for half a year, of course I miss the ground, I'mmissing my family and I'm really looking forward to seeing them again."
Earliertoday, Reiter aided his fellow ESA astronaut ChristerFuglesang, Sweden's first spaceflyer, set a new Frisbee toss world record [image].
Fuglesang,a former Swedish national Frisbee champion, kept his Frisbee aloft for 20seconds while Reiter timed him. The feat was part of a discussion with Sweden's Crown Princess Victoria, politicians and schoolchildren.
Theprevious record, 16.72 seconds, was set by Don Cain of Philadelphia, Pennsylvania, according to the World Flying Disc Federation.
"We wereactually throwing it around in the tunnel between the shuttle and the spacestation, and I needed the practice," said Fuglesang, who like many of his STS-116crewmates is making his first spaceflight. He reported some nausea, back painand other ailments in the first few days, but they ultimately subsided.
Fuglesanghas made his first two spacewalks during Discovery's STS-116 mission alongsideCurbeam. Their latest excursion, a five-hour outing to rewire the space stationfrom a temporary electrical set up to a permanent power grid.
Fuglesangsaid he and his Discovery crewmates are enjoying their spaceflight, but lookforward to returning to Earth. Their shuttle, he added, is in fine shape.
"It's goingto be very fun coming back," said Fuglesang, who spent 14 years as an ESA astronautbefore launch on his first flight. "Not that I'm in a hurry to come back, butit's going to be fun."
