Will a Starship attempt landing on Mars in 2027?

On-orbit propellant loading seems to be a key milestone to watch out for. It would be very cool if that could be achieved within the next couple of years.
Just imagine the huge scope of BEO missions this could open up for NASA, once that threshold has been crossed.
But are NASA planners actively preparing in advance for this, or will they just react once the capability is available in tangible form?

Probably the latter, and maybe not immediately then, because NASA would need to be funded for missions that take advantage of it.

there was talk of a 2026 Earth-Mars transfer window , the Japanese will launch the Martian Moons eXploration (MMX) not a landing attempt, it is a robotic space probe set for launch in 2026.  It seems the Japan spacecraft will launch on a H-3 rocket or a medium lift version of launcher by Mitsubishi Heavy Industries
