So... That Wolf... I see quite a few potential separate stories in what you wrote. Some I know about, some I wasn't aware of.
Spider goats aren't that new. There's a whole... herd, flock... whatever the collective noun is of goats... being milked and their milk processed to extract the spider-silk protein which we've learnt to tease into our own spider-silk, in quantities way beyond those we could ever have farmed from actual spiders. (Yes, we
also do that.)
It's potentially good stuff for body armour, and thus (doubtless) space-suits.
If one escaped, that's perhaps of concern if there's local wild goats (or a separate escape out of/unescape into another captive group of goats without anyone realising) and enter their family tree, but I'm not sure how likely that is.
We can breed humans (slower than we can goats, and potentially with more complaints) but I'm not sure what we'd do for space. Nocturnal vision would be less useful than some form of chitinous (or silk?) exoskeleton, if you mean for
actual space, rather than microgravity, in which case make sure you add strengthened membranes and sphincters to the list. Night-vision would also be less useful than enhanced UV filters for the eye (and, if not already dealt with by the other enhancements, skin).
The colossal blob of liquid water is news to me. You're not thinking of the (salty) liquid water on Mars thing, are you?
Sorry... ...are you!!!
