I still don't understand how Musk can promise a Mars launch next year every year and not at least send something, no matter how small, to Mars.
It would hardly be the first time he' demonstrated a casual approach to the truth
It would be a waste of time to develop right now, if it isn't on starship it would be a dead end in terms of progress. So they are better off just waiting until starship can be sent.
I guess they haven't had a customer who has wanted to send something to Mars yet. If they have sent something to Europa it's not like Mars is harder.
Blue Origin got patents on landing on a drone ship a decade ago. Until today they'd never done it.
