Wow, this one is big!

And yes, launch was scheduled for 2008, but there was a general meeting last month (ref. laspace.ru) and looks like they are on track for launch this year! And they will use a Zenit rocket this time.

Main scientific goal of the mission is the study of various astronomical objects with unprecedented angular resolution up to few millionth of an arcsecond. The resolution achieved with RadioAstron will allow us in principle to study the following phenomena and problems:

* central engine of AGN and physical processes near super massive black holes providing an acceleration of cosmic rays - size, velocity and shape of emitting region in the core, spectrum, polarization and variability of emitting components;
* cosmological models, dark matter and dark energy - by studying dependence of above mentioned AGN's parameters with redshift, and by observing gravitational lensing;
* structure and dynamics of star and planets forming regions in our Galaxy and in AGN - by studying maser and Mega maser radio emission;
* neutron (quark?) stars and black holes in our Galaxy, their structure and dynamics - by VLBI and measurements of visibility scintillations, proper motions and parallaxes;
* structure and distribution of interstellar and interplanetary plasma - by fringe visibility scintillations of pulsars;
* building of high accuracy astronomical reference system of coordinates;
* building of high accuracy model of the Earth gravity field.

I say... WOW! WOW!

The Russians have tried radio telescopy from LEO before -- for example, the KRT-10 they hung off the back of Salyut 6 back in 1979. As I recall, they didn't get much in the way of good data from it...

Indeed, a fairly concerted search hasn't turned up any mention of results in the usual Russian journals or observatory publications (note to close followers of Salyut - I'd be pleased to hear of any!). This is in contrast to the power-hungry BST-1M submillimeter telescope on Salyut 6. As best I can tell, it was used mostly for terrestrial and airglow observations, but did obtain some detections of more distant targets such as Jupiter.
