The shuttle 'Endeavour' has undocked from the International Space Station (ISS) and heading home after efficiently installing the Tranquility Node at the research centre.

The shuttle and its six-member team will land in Florida at 0316 on Monday.

As the vehicle parted with the ISS at 7.54 p. m. EST, pilot Terry Virts flew the shuttle to 450 feet in front of the station and then in a circle around the station before starting the drive to the earth.

The space operation was set up by the NASA Feb 8.

During the 9-day operation, spacemen set up the Tranquility node and a "cupola" with 7 windows, which will offer up a panoramic 360 degree sight of the earth, space objects and visiting space vehicle.

With the addition of $400-million new instrumentation, the space station is now 98% complete in terms of volume and 90% in terms of mass.

Four more shuttle trips are planned by the next seven months in order to supply added equipment and spare parts to the space laboratory, NASA said. (With Input from Agencies)
