Pot, meet kettle
Don't be an idiot - how many comets have you landed on? I would prefer to talk about the amazing achievement and put it alongside the great successes of others, particularly NASA, but if we're resorting to purile one-upmanship then I'm game for that. I could point out that Beagle 2 was a low budget mission, about $100 million in today's money. Perhaps I should list a few other failed Mars missions and their rough budgets in today's money:
Mariner 3 - ~$300 Million ($55M 1970$) - Failed - Fairing didn't separate
Mariner 8 - ~$300 Million ($55M 1970$) - Failed - Didn't get into orbit
Mars Observer - ~$1300 Million ($813M 1993$) - Failed - Lost comms before orbital insertion
Mars Climate Orbiter - ~$460 Million ($327M 1999$) - Failed - Burned up
Mars Polar Lander - ~$155 Million (110M 1999$) - Failed - Landing failure
Deep Space 2 - $47 Million (29M 1999$) - Failed - No data returned
Why not applaud the successes of the incredibly complex decade-long flight and landing and note the fact that the primary objectives were only 60 hours long and it looks like they'll achieve most of them.
Whichever way you look at it it's something to celebrate.
