Canada plays 'critical role' in building next space telescope

I honestly think the article overhypes Canada's contribution, but what we did certainly is useful. 

Unlike the Hubble telescope, which orbits about 550 kilometres above Earth, the Webb telescope will be positioned in deep space — about 1.5 million kilometres from Earth. Although that will allow the Webb to capture images the Hubble couldn’t, it also means it will be out of reach for servicing, and it has an estimated maximum lifespan of 10 years.
