We'd get the largest baseline when the Sun is between the planets. This of course blocks interplanetary communication.
Another commenter mentions the 0.5 mm precision needed[0] - how would we overcome the communications issue to get an accurate measurement?

- NeutronStar 8y agoHow long of a time would the Sun be blocking the Earth from Mars?
- lainga 8y agoI imagine the same way the article's array does: with an (interplanetary) version of sneakernet [0], taking independent measurements which are then delivered to be correlated in one place. I think you could keep atomic clocks on Mars and Earth in sync with extremely accurate calculation of the Earth-Mars distance at any time, and thus the propagation delay between them.
