1983, he became a visiting scholar at Stanford
University under Nobel prize|Nobel Laureate Arthur
Leonard Schawlow|A.L. Schawlow. He is a
laser-physicist, and his research has included
work on electro-optics, laser-induced fluorescence
of particles and crystals and multi-photon laser
spectroscopy.

In December 1983, Dr. MacLean was one of six
astronauts selected by the Canadian Space Agency
(CSA). He began astronaut training in February
1984 and, in December 1985, was designated as the

Strategic Technologies in Automation & Robotics
Program (STEAR).

From 1987 to 1993, he was program manager of the
Advanced Space Vision System (SVS). In July 1992,
NASA agreed to outfit the shuttle fleet with an
operational version of the Orbiter Space Vision
System (OSVS) which will give eyes to the Canadarm
on board the space shuttle, and the Advanced
Vision Unit (AVU) which will be used with the
Mobile Servicing System (MSS). The MSS is
Canada’s contribution to the International Space
Station. MacLean was Program Manager for the OSVS
until his interim assignment, in July 1993, to a
collateral duty as Science Advisor for the
International Space Station.

In 1993, he became an adjunct professor at the

Studies.

In April 1994, he was appointed acting

program. In July 1996 he was selected to attend
NASA’s Astronaut Candidate Training at Johnson
Space Center in Houston, Texas. Having completed
two years of training and evaluation, he is

specialist. MacLean was initially assigned
technical duties in the astronaut office robotics
branch. More recently, he served as a Capsule
