Are you speculating that based on familiarity with her work or general principles about how things may work? Given what you say about the timeline being strange, and how that seems to be what motivates this speculation, I suspect maybe you haven't had a great deal of exposure to her, and so this conversation about her views on space travel might give you a skewed impression of how important to her space travel was? And therefore, how likely she'd be to make profound compromises for those views?

No familiarity -- just my observation of artists and authors being particularly inscrutable people.
