Yes. It's my interpretation of the outer space treaty that it does not actually address the issue as to whether commercial space mining is allowed or not allowed. That issue was left until later—and fair enough, it was 1967—but that issue is the centrepiece of some pretty important international diplomacy right now. It's not just whether commercial space mining is allowed, but if it is allowed, then what are the restrictions on that? What are the necessary safety and security considerations? How do you coordinate between different actors, for instance, on the moon? That's at the heart of diplomacy these days.
There is a working group at the United Nations committee on the peaceful uses of outer space, which is engaged in a multilateral investigation of this very issue. Canada has a lot that it can bring to the table—our expertise in terrestrial mining, obviously, and in multilateral diplomacy, finding compromise and bringing everyone to an agreement in what is a consensus-based organization.
I just want to use this opportunity, however, to point out that mining in space will be a thousand times more difficult than mining on the surface of the planet. The safety and security elements of this issue of space mining are something that need to be front and centre. Lest we get caught up in the excitement about the possible economic benefits—there's a lot of enthusiasm, a lot of hype with regard to space mining—I would like to remind people that this is an extremely dangerous and difficult environment with extreme distances, the vacuum of space. Challenges, like lunar dust alone, make me hesitate on a lot of the proposals we hear about. There will be a future for space mining one day, but it's not coming quickly, despite what a lot of entrepreneurs would want you to believe.
