Following Sarnia, Ont., native Chris Hadfield's installation of the 17-metre-long arm, Canada gained access to 2.3% of the laboratory space in the non-Russian part of the ISS. COLUMBUS MODULE

Despite the British government's initial objections to the cost, the European Space Agency is committed to building the Columbus, a lab for medical and scientific experiments. SOLAR WINGS

The blue-and-gold wings were placed into position by the deft robotic-arm manipulation of astronaut Marc Garneau, the first Canadian in space.

They comprise the largest structure ever deployed in space. ZVEZDA SERVICE MODULE

The very first piece of the ISS-Zarya, or "sunrise" in Russian-shot into orbit from the Baikonur Cosmodrome in Kazakhstan. That's the same place where Sputnik I launched in 1957 and where Yuri Gagarin, the first human in space, blasted off in 1961. LEONARDO, RAFFAELLO AND DONATELLO

Installed: 2001 and 2004 Cost: $230 million

The three Italian modules serve as the station's moving vans, carrying around equipment, supplies and experiments. Leonardo went up first on the shuttle Discovery. Raffaello was part of the cargo of the recent Endeavour mission. Donatello is due to launch in 2004.
