"...tides and radioactive elements, which could provide important catalysts for the development of life. Future missions to Enceladus can be designed to look for evidence of life..."

Oh jeez get over it will ya? Life life life. How living-centric of you. Check your alive privilege.

OK I'm joking about that part, but surely there must be a few good reasons to explore space besides whatever it has to do with life and the support thereof? Is an ocean of liquid methane not interesting in its own right?

I genuinely wonder whether people who write like this are going to be totally disappointed and give up space exploration if they find there's no life out there. Which (let's be honest) is what they will probably find. Or is it more that they're trying to pander to the reader because they think that's all we care about?
