„Refilled in cis-Lunar space by commercial launch vehicle“ where one of the commercial launch vehicles displayed is a complete Mars & Return package that uses reusable rockets for every step portrayed in this plan as being performed by disposable components.

WTF? The QR code leads to a dead page. What’s the point of using a QR code and a shortener URL service?

There are 16 SLS launches involved in this. Even at the „lower“ end price of $2.5 **b**illion, that’s $40 **b**illion just in SLS launches alone. And each SLS is Block 2, which doesn’t exist yet, so that’s even more money!
I don’t really see how this is feasible.

So this plan includes Starship and NewGlenn to refuel, but still requires 16 SLS launch’s which would probably be around 40-60 billion dollars in launch costs alone. Why would you not just use commercial rockets for the entire mission? SLS only makes sense when you completely ignore the existence of cheaper, faster commercial alternatives. It all falls apart when you try and include them in your mission plan. Also a launch rate of 2 times a year sounds quite ambitious for SLS, and would also mean completely abandoning Artemis and the moon for like 8 years, because no way is SLS launching more than twice a year under any circumstances.

I find it hard to believe that:
* SLS can achieve a low enough cost to make this realistic.
* SLS can attain a high enough flight rate to make this achievable.
* In a world where Starship/New Glenn are flying often enough to refuel the Mars ship, that we wouldn’t just use them to also launch the hardware components.
