I appreciate that. That's fine. We did request that the foreign affairs minister come to our committee. We haven't been able to get that.
Let me go back, then, to CSA investment and some of the questions I raised earlier. I regret that I'm trying to get so much out of my time, because we have such limited time. But can you tell me why the space agency and Canada refused to partner with the Europeans around the Mars rover investment? That's an investment that MDA, of course, was hoping to get. What was the rationale there?
