when we have colonies on mars, they will need to be on a different chain, as it is more than 10 light-minutes away. will you stack any martian btc in that case?

Could they technically still run on lightning? There would just be a few channels connecting earth with Mars and/or what ever communication relay we have set up in between?
yes, they could still transact on the earth-chain, but could never mine blocks out there. the horizon is some sliver under 10 light-minutes away, as you couldn't submit a block in time. sometimes you might sneak one in, but you're playing at a huge disadvantage as even when you got a block, you'd likely not get it the rest of the network in time.
