    In June,2007,a group of students from eight highI'm daydaytest Placeholder!

schools in Winnipeg, the capital of Canada's ManitobaProvince, will begin test-launching

(试发射) a satellite the size of a Rubik's cube.

The one-kilogram WinCube satellite,

named for its home city and its shape, will be put into low orbit. Once in space,it can

perform for a few months or up to several years, communicating information  that could

help find the early signs of earthquakes.

    

     There are 80 similar satellite projects worldwide, but this is the first high school based

program of its kind in Canada, 30 Manitoba high school students are having a hand

in designing and building the satellite, in cooperation with aerospace (航空航天的 )

experts and 10 students from the University of Manitoba, and with support from two other

organizations.

    The Win-Cube project is not something that goes on a piece of paper; it is real-world

engineering, allowing high school students to have an opportunity to learn more about the

exciting world of engineering through their participation in this challeng-ing program It is

also taken as a wonderful example of the unique partnerships within Manitoba. Designing,

building and launching a satellite with high-school participation will bring this world-class

educational project into reality and Manitoba closer

to space.

    "These Manitoba high school students deserve congratulations for their enthusiasm,

innovation (创新) ,and a  strong love for discovery,"said Education,Citizenship andYouth

Minister Peter Bjornson. "We want to make science more relevant c相关的) ,interesting

and attractive to high school students by showing them how classroom studies can relate

to practical experience in the workplace or, in this case,in space,"Bjornson added.

      The Win-Cube program is mainly aimed at inspiring a strong desire for discovery on

the part of the students. It also shows Manitoba's devotion to research and innovation and

the development of a skilled workforce-all important drivers of knowledge-based economic

growth.
