I'm very happy to be home again. The 30-hour journey back was arduous, complicated by extremely long lines at immigration and security at Dulles Ariport in Washington.
I heard from a friend at the Astro-Space Center that Radioastron has successfully opened: it has unfolded its "umbrella". This was slightly tricky, with thermal stresses holding things up initially. The next step is to find fringes. That may be hard.
