You haven't addressed spacetime geomety at all. Give it a whack.
And, again, you missed the point. As a citizen and taxpayer you'd be somewhat familiar with the costs of the Mars Program even if you didn't bother to look at the details. It's public information available today. As a scientist you should have made the fiscal connection between your project and the Mars Program. You missed this aspect of your story because you don't understand either spacetime geometry or the implications of time travel. It never occured to you that $25 million to go to Mars with a technology already available versus $100-200 billion might be of some interest to your President, SecDef, Congress and the tax-payers in general. I'm assuming that $200-300 billion had already been invested in Mars Program R&D (I didn't ask about R&D costs, didn't I?).
No, lad, I think that I'm holding my own quite well here. You haven't shown us that you have any scientific background at all and you most certainly have shown that you have no instinct for managing a budget, have never been involved in a government agency budget prep process, OMB or Congressional budget hearings.
