I'm not aware of any such measures that can be taken without centralising the currency.

Similar to a timestamping server here on Earth (or yes, even an ICANN like construct, but that is centralization, indeed). It will be in the Mars colonists' economic best self-interest to install server(s) that issue a list of timestamp marked credentials - which could be incorporated in each block to verify the mining occurred on Mars.

If a centralised system is desired, no blockchain is necessary at all.
Earth does not have any such timestamping restrictions on blocks.

Raising the money is done with the premine. Beyond that, it doesn't help raise money at all.

Yes it does: the 300k (now 400k) of premined Marscoins are worth nothing at this point (well, on reddit they go for 10-80cents right now). If the incentive is strong enough, more and more fiat currencies will be exchanged for Marscoin driving up the price for Marscoins. That alone will make the initial premining worthwhile and allow MarsOne to actually make use of it. Maybe I should have said "allows to fund activities and make purchases in fiat related to the actual mission roadmap" instead of "raise money".

Higher supply decreases value, not increases it... so this doesn't really argue why it should be increased quicker.

Let me know what needs to be done, in your opinion, to convince you of Marscoin? Curious!

Well, now it sounds like the goal is a centralised system masquerading as a decentralised one...
I'd be more inclined to support a system that improves on Bitcoin (or at least retains its functionality) rather than seems to be introducing new problems without addressing the existing ones.
