That's certainly an accomplishment
As the US learned in the 1990s, even putting something in orbit around Mars is a substancial challenge. We lost two spacecraft trying to do that. The Russians had trouble in the 1980s with their Phobos 1 & 2 probes as well, although one of them was lost well before orbital insertion.
As for the Beagle 2, I continue to hope for success but I'm not overly optimistic. It sounds like they might well have cut too many corners to meet very tight budget and schedule pressures. Quite often, buying on the cheap is no bargin.
