Thanks for the question, Mr. Chair.
NORAD doesn't watch objects in space. What we do is watch terrestrial launches towards space. Of course, what we're watching for, predominantly, are ballistic missiles or missiles that could become hypersonic missiles. We also see all re-entries. We do this through what's called OPIR, or overhead persistent infrared. It's a satellite system that essentially watches the earth constantly.
Watching objects in space is absolutely a U.S. Space Command responsibility, and Space Operations Command. We're obviously concerned about anything that might have been in space for a period of time and could de-orbit and become a ballistic missile or hypersonic weapon. We're always watching for re-entries.
Again, we're not monitoring space specifically. U.S. Space Command does that, as do the Canadians in the SpOC.
