Excerpt from a News article by Jenny Hogan in the December 1, 2005, issue of Nature:
"The [funding] situation has led to speculation that BepiColombo, a mission destined for a 2013 launch to Mercury, might be cancelled. 'That is the big danger painted in the sky,' says Karl-Heinz Glassmeier, principal investigator on one of the instruments proposed for the spacecraft. "Nerves were set jangling about the project, which also involves the Japan Aerospace Exploration Agency, after it was postponed because the initial design was too heavy. That problem seems to have been solved, but officials say the estimated cost of the mission, at 600 million [euros] to 650 million [euros], is still more than 100 million [euros] above target."

Any plans of using for example MMO -probe as a crash-lander at the end of primary mission to get some extra data from the surface, while MPO would do the imaging a'la Deep Impact? Or in case of MMO missing the necessary engines/thrust doing it vice versa? And is it so, that on those orbits around Mercury (just like Messenger), without any intervention, these probes' orbits don't decay in a traditional sense but they will get longer and higher until Sun's gravity pulls them on a heliocentric orbit...? And what would be the limit/distance for Mercury to keep a probe on a stable orbit around it?
