Canadian Patch

This patch commemorates Mission STS-115, Flight Assembly 12A. It highlights Canadian Space Agency Astronaut Steve MacLean's spacewalk as well as his becoming the first Canadian to operate Canadarm2 and the Mobile Base System
in space. The patch was designed by graphic arts students of York University Graham Huber, Peter Hui, Gigi Lui.

The sunburst illustrates the importance of the mission's primary objective: the successful installation and activation of the solar arrays.

The Canadian maple leaf rising from behind the Earth emphasizes Canada's partnership as one of the 15 nations building the Space Station.

The red star over Astronaut MacLean symbolizes the evolutionary role of the Space Station in providing a unique orbiting science laboratory that will act as a stepping stone for the next destination in space: the planet Mars.
