Yes, calling it "cross" galactic would certainly be stretching the definition of "cross". Though I suppose a "cross country" race is across the "countryside" though not across the country. ;)

Interstellar?

What is the best term for inter-solar-system travel? (Or, is that the best term?)

[jlgreco]

"Interstellar" probably. Between the stars.

I agree. I think I actually meant to ask about "intra-solar-system" travel.
