Steve Maclean - STS-115 Mission Patch

The Mission

It's back to work building the International Space Station (ISS) with the upcoming flight of the Space Shuttle Atlantis.

In this mission, STS-115, Canadian talent and technology are front and centre. Veteran Canadian astronaut Steve MacLean, (YES I Can! Science's Honourary Science Team Director), and the other members of the Atlantis crew, commander Brent Jett, pilot Chris Ferguson, and mission specialists Joseph Tanner, Dan Burbank, and Heidemarie Stefanyshyn-Piper, will continue construction of the ISS, delivering and installing new truss segments and solar arrays.

Installing these new components will have MacLean performing some of the most challenging tasks ever done by any Canadian astronaut. Over the course of the mission, he will be choreographing a series of complex robotic manoeuvres using Canadarm2 to perform assembly tasks—a first for a Canadian astronaut—and a 6.5-hour spacewalk to install the power generating panels.

Science Activities for Public Outreach and Classroom Teachers

YES I Can! Science BannerThe McMaster University YES I Can! Science Team is very proud to have worked with Dr. Steve MacLean and the Canadian Space Agency to prepare the following classroom and outreach activities.

Astronauts can take a small number of items with them into space as mementos of their mission. The objects are meaningful for the astronaut personally, for the Canadian Space Program in general, or, since the lives of astronauts are closely tied to the space program, a combination of the two. The YES I Can! Science Banner to the right commemorates our work with Steve MacLean and will fly with him on his mission.

Star Count

Shake, Rattle and Roll: Structures in Space

This important, and fairly easy to perform Star Count experiment is designed as part of an international scientific study to investigate the visual quality of the nighttime sky and to help assess the national and global extent of atmospheric light pollution. It will also help to evaluate the amount of energy wasted through poor or inappropriate lighting practices.

Conducted onboard Space Shuttle Atlantis by Canadian astronaut, Dr. Steve MacLean, this experiment requires the assistance of many ground-based observers. Teachers, students, youth organizations ( e.g. Cubs, Scouts, Guides etc.) amateur astronomers, science and environmental organizations, and dedicated interested individuals, are all invited to participate.

This curriculum guide deals with structures, forces which act on them, and properties of materials. It is intended to give teachers a broad overview of forces acting upon structures on Earth and in space. Teachers will use those sections of the guide that best meet the interests and abilities of their own students.

The focus of the guide is a classroom experiment whereby students perform a quantitative study of forces (producing a torque) acting on the unsupported end of tubes of various length.

An identical experiment, performed onboard Space Shuttle Atlantis by Canadian astronaut, Dr. Steve MacLean, will provide a set of observations which students can then analyze and compare to their own results.
