In this case, the black hole image was created with radio interferometry, in which you can separately record electromagnetic waves from individual radio telescopes and then combine them electronically after-the-fact. Visible and infrared interferometry is much more technically challenging because the frequencies are orders of magnitude too high to record in the same way, and so it hasn't really been successfully applied in space. (See the Space Interferometry Mission[0] for one sort-of attempt at this kind of thing.)
