Astronauts Open Space Station's New Room
Shuttle Discovery and Expedition 16 astronauts talk with reporters from inside the new Harmony node aboard the International Space Station (ISS) on Oct. 27, 2007, after the module was opened earlier in the day.

The station?s Expedition 16 commander Peggy Whitson and Italian astronaut Paolo Nespoli opened the hatch to the nearly 16-ton Harmony module at 8:24 a.m. EDT (1224 GMT), commemorating the event with a brief ceremony.
?It?s a pleasure to be here in this very beautiful piece of hardware,? Nespoli said of the Italian-built Harmony node which he and his STS-120 crewmates aboard NASA?s shuttle Discovery helped install during a Friday spacewalk.
Nespoli and Whitson wore protective goggles and masks inside the node to guard against any loose debris shaken free during the module delivery to the ISS. They also took air samples after floating into the new orbital room.
Harmony in space
Named by students in a NASA contest, the Harmony node serves as the docking point for European and Japanese laboratories to be installed during future shuttle missions.
?We think Harmony is a very good name for this module because it represents the culmination of a lot of the international partner work,? Whitson said during the node?s christening.
The school bus-sized connecting node was temporarily attached to the space station?s Unity module on Friday and will be moved to its permanent position once Discovery leaves the ISS on Nov. 4.
?We?re just getting it suitable so we can go in and get the work done,? said ISS flight director Holly Ridings late Friday. ?But [we?ll] not actually do anything permanent in there so that it can be moved again.?
Astronauts connected power and data lines to the Harmony module earlier today to power up its internal systems. They will then begin the busy task of replacing valves and removing more than 700 bolts that secured the module?s internal components in place during Discovery?s Oct. 23 launch.
?At one point, originally in the mission, it was not a requirement for us to go inside,? Discovery?s STS-120 mission commander Pamela Melroy said before the spaceflight. ?And the crew said, ?No way! We want to go inside!? We were excited about that.?
Melroy presented Whitson with a necklace bearing a Harmony module-shaped charm after the node was opened.
The Harmony module increases the internal volume of the ISS by about 2,666 cubic feet (75.4 cubic meters), bringing the station to a total of more than 17,000 cubic feet (481 cubic meters). When complete in 2010, the station will include some 43,000 cubic feet (1,217 cubic meters) of pressurized volume and enough habitable space to rival a five-bedroom home.
Earlier, NASA astronaut Clayton Anderson previewed Harmony?s grand opening today with the song ?Harmony.?
?So that was a little Elton John welcoming her to the fold,? said Anderson, who is returning to Earth with Discovery?s crew.

?I think it?s prime real estate, because it is at the front and it?s at the nexus of three primary pressurized modules,? Discovery pilot George Zamka has said of Harmony node before flight.
Installing and outfitting Harmony is one of the major goals for Melroy and her STS-120 crew. During their planned 14-day mission, astronauts will also perform a total of five spacewalks and move a massive solar array segment to the port-most edge of the station?s backbone-like main truss.
The Discovery crew awoke at 1:38 a.m. EDT (0538 GMT) today to the song of ?Bellissime Stelle? - Italian for ?Beautiful Stars? - sung by Andrea Bocelli. The tune was chosen specially for Nespoli.
?We certainly hope that you've had a little bit of time to look out and see the beautiful stars since you've been up there in space,? NASA astronaut Shannon Lucid radioed Nespoli from Mission Control here at the Johnson Space Center.
?Yes, stars a really beautiful and from up here they're even more beautiful,? Nespoli said. ?Thank you to everybody who made this possible. I really appreciate it.?
