The MMX mission is the first sample return mission to the Martian sphere, with the goal of returning 10g of material from the moon Phobos.

By which I mean the delta V for TEI from Phobos has got to be pretty minimal, but I wonder how much delta V on top of that must be created to escape from Mars' gravity well.
