Ungrappling approved and complete

Ground controllers have given the go ahead to ungrapple the Canada II robot arm from pressurized mating adapter 3, after several fault readings delayed work for nearly a hour.

"Flight controllers are reporting that the arm has ungrappled from PMA-3," reported NASA commentator John Ira Petty.

"We're going to head to the chow hall," said ISS flight engineer Clay Anderson, who planned to break for lunch.

Ground controllers will handle the final installation of the docking module, which has been used by several shuttle missions.

Wearing yellow construction hats, gag gifts from the Endeavour crew, the crew of the International Space Station began robotically moving PMA-3 at 5:30 a.m. EDT today to make room for the Harmony node, which will arrive in late October aboard shuttle Discovery.

Unbolting the 2,607-pound PMA-3 began at 6:08 a.m. EDT, after the robot arm grappled PMA-3.

The Harmony node will anchor the European and Japanese laboratories, which have been held at Kennedy Space Center due to delays in shuttle flights.
