TEL  AVIV -- Canada's first astronaut Marc Garneau has seen a lot of things  most ordinary mortals never will. But even he was taken aback by the  school project of a group of Israeli teenagers this week.
Mr.  Garneau could hardly believe it when 15-year-old Tal Pritzker and his  fellow students in the Space Technology group at the Meyerhoff Technical  School in Tel Aviv showed him their latest project: a satellite and  earth-tracking station that should be ready for launch in about two  years.
"I'm amazed by what you've done," he told them. "I'd like  to hire you all. It was very impressive. I don't think I've ever met  youngsters who are so well informed."
"I was bowled over," he  said in an interview. "There is a school named after me, the Marc  Garneau Collegiate Institute, where we teach space sciences, but they've  never actually built a satellite."
Mr. Garneau, president of the  Canadian Space Agency, is leading a week-long trade mission to Israel  to sign a co-operation agreement with the Israel Space Agency on Earth  observation, small satellites and encouraging young people to learn  about space.
It is both his and the agency's first visit to  Israel. He is accompanied by representatives of six Canadian companies  that are active in space technology and eager to explore commercial  projects for the first time with their Israeli counterparts.
"Space  gives us a unique perspective on our world. Seen from space, the Earth  is one tiny, fragile, blue planet in an ocean of infinity. It's clear we  need to work together and to help each other if we're going to preserve  this planet," he told the students.
During his first flight, Mr.  Garneau said he watched with alarm as a pall of smoke covering one  million square kilometres settled in the upper atmosphere from the  burning of the Amazonian rain forests. As the shuttle continued on its  orbit, he saw evidence of man-made disasters across the globe.
Over  Kazakhstan, he saw the dried-up Sea of Aral, once the fourth-largest  body of inland water in the world, drained by the Soviets for  irrigation. "It had terrible effects. It dried up, then the minerals in  the dried-up areas blew over the land and essentially sterilized it."
Mr.  Garneau said that Canadian scientists are working on programs triggered  by space observation and exploration to tackle these and other  environmental problems, including climate change and the depletion of  the ozone layer.
The five-year, $5-billion budget for space  research just announced by the government will keep Canada at the  cutting edge, he added.
"We've learned a great deal about  computer technology by rising to the challenge of sending rockets into  space," he said. "The technology that we developed to build the robotic  arm for the U.S. space shuttle, the Canadarm, in the early '80s, is now  being used to perform robotic surgery."
Canadian medical  scientists have gleaned vital information on bone loss from osteoporosis  which occurs at 10 times the normal rate in astronauts because of  weightlessness. A direct result has been the development of a new type  of fake bone, Skelite, that can be used to help people heal faster after  surgery.
