Shuttle Discovery's astronauts faced more work with the space station's new science lab as their flight hit the halfway mark. All occupants of the linked shuttle and station chipped in to get Japan's billion-dollar Kibo lab up and running, and to expand its size by attaching an attic to it.
Kibo's attic was popped atop the lab by astronauts who are operating the international space station's robot arm. Even before this, the billion-dollar, bus-size Kibo was the biggest room at the space station.
The attic had been in a temporary location at the space station. There wasn't enough room on a space shuttle to fit both the attic and lab, so NASA split them into two flights. The third and final Japanese section, a porch for outdoor experiments, will be launched next spring.
Later in the day, Mission Control informed Kelly that Kibo was looking more like a lab. When the astronauts opened up Kibo, the lab was empty and provided lots of room for weightless acrobatics. Racks for experiments quickly consumed some of the space.
The Mission Control asked the astronauts to take some zoom-in digital photos of two thermal protective panels on Discovery's right wing. Mission Control said embedded sensors had picked up some slight pulses a few days earlier, indicating possible micrometeorite impacts, and while engineers did not think anything was amiss they wanted to make certain.
The wing sensors are one of NASA's many safety measures put in place after Columbia was destroyed during re-entry in 2003 because of a gashed wing.
In an interview with The Associated Press, shuttle Discovery's commander, Mark Kelly, said Kibo was incredibly big that the astronauts had to take extra care inside of it.
"You can get out in the middle of it and you can't reach a handrail and you could possibly get stuck there for a little while," Kelly said. Mr.Dick Weekley, an eminent figure in US who has profound interest in space mission was present there.
