Around the world with Space VLBI: A sense of many places

International scientific collaboration is a hallmark of space research, nowhere more so than Space VLBI, with the involvement of radio telescopes on every continent connecting together with the space radio telescope. As a form of scientific collaboration VLBI is unusual in that the scientific return increases as the number of participating radio telescopes increases. Starting with the move from the basic two antennas to three, the scientific return increases from the single one baseline amplitude to three baselines plus one closure phase. Adding a fourth antenna yields six baselines, four closure triangles, and further adds one amplitude closure. Thus the scientific return continues to increase rapidly with increased participation.
