Upgrading the International Space Station

The International Space Station (ISS) will be the largest
human-made object ever to
orbit the

The station is so large that it could not be

launched all at once --
it is being built piecemeal with large sections added
continually by flights of the
Space Shuttle.

To function, the ISS needs
trusses to keep it rigid and to route
electricity and liquid coolants.

trusses are huge, extending over 15 meters long,
and with masses over 10,000 kilograms.

Pictured above earlier this month,
Robert L. Curbeam (USA) and
Christer Fuglesang (Sweden) work to attach a new truss segment to the ISS and begin to upgrade the power grid.
