I count that at the base of 350,000 km with working wavelength the resolution in interferometer mode will be 10 microarcseconds that is equal to 2000 km to Alpha Centauri (4.36 light years). With such a resolution, theoretically, we could see continents and oceans on a hypothetical Earth-like planet at Alpha Centauri. However, a twin antenna interferometer gives the resolution only at one axis. We must make dozens of observations at different tilts at basis line, or launch more RadioAstrones. Russia has another project: The Millimetron ("Spektr-M"). This is a 12-m radio telescope with a working wavelength of 1 mm. It will have an even greater (x 10) resolution than RadioAstron.

That's actually pretty amazing, we should be able to see planets at Alpha Centauri In decent detail then, that will be awesome.
