I think a few things are important. One is the next step that's being taken, which is adding a satellite to the Sapphire—the Sapphire 2 we could call it—for deep space surveillance, although it's primarily to surveil the vital geosynchronous orbit.
There has been some discussion, which would also be a good step, of going back to what we used to have in the sixties until the eighties. That would be two optical ground stations to facilitate the surveillance of space. There's no clear indication that this will proceed, but those would assist us.
In the context of NORAD, it's unclear to me what Canada could or could not do. It can do lots of things, but in terms of the surveillance of space, the key thing to know when space is under attack is what we might contribute to surveillance from space—the DSP system. That's to ensure there's enough redundancy, because that is key to being able to identify launches. Once you identify launches, you can quickly calculate where they're going—whether they're going into orbit or not or the orbital path they're going to take—and whether they're using a type of ballistic missile, such as a fractional orbital bombardment system with a depressed trajectory that needs to be tracked.
