The people of Canso asked, “Why Canso?” It's a great place to start in answering your question.
They describe the place as, “It's not the end of the earth, but you can see it from here.” It's a great description when you want to launch a rocket over thousands of kilometres of open ocean.
On low-earth orbit, our highest altitude is 700 kilometres. The key differentiator I would point out is the sun-synchronous polar orbit. Most launches that have been happening over the decades have been equatorial launches, where you're launching around earth and you're staying over one place and communicating up and down.
When you have the earth spinning in this direction, and you're coming from the other direction, you have much more coverage over the entire earth. A couple of times a day you have these satellites that are going over the same spot on earth and providing data down. If you could build a constellation, then that is meshed and surrounds the earth. Now you have an inter-network. You are providing global coverage, not only nearly real-time, but actually real-time data, real-time communication and real-time Internet in that sense.
That's what the real opportunity is. It's also really great for near-earth imaging. When you're monitoring a forest fire, an earthquake zone or a hurricane, you are able to get that real-time data and observe our earth, not have that satellite go away and have this big gap. You have the ability to track that.
