Beagle 2 Failure Analyzed 139
InsomniaCity writes "An inquiry into the loss of the Beagle 2 Mars probe in December will criticize the management of the project and the testing of the lander, says the BBC. Following the loss, the European Space Agency (Esa) and the British National Space Centre established a Commission of Inquiry, that are now recommending 19 things we need to remember for the future, from project management and fund raising, to high altitude testing of the parachute system. The commission, however, did not pinpoint any particular technical failure."

A few weeks before the launch, there was a doumentary on the BBC about the probe. It was basically a one-man struggle to get the thing there, despite tight deadlines. I also noticed that some of the critical equiptment, I think including the parachute that they used, remained untested. (The one they tested broke during testing!) It was amazing that it even got into space, but there were definately worries about wether it would work or not before it was launched.

I was debating with someone recently who kept insulting the shuttle, and referring to Ariane. I then showed the person how much of a disaster the Ariane program has been as well - Ariane 5 having three failures in 18 paid launches, the cost overruns driving their price up (not as high as the shuttle, but still not that great), the bailout of Arianespace, the cancellation of the ESC-B upper stage, etc. The person's response? They picked another rocket system to use as their champion, ignoring the fact that *it* had its own problems too.
To make it worse, many of the people who trash space agencies treat ameteurs as if they're the ray of hope for the future. The ameteur rocket industry has been one failure after another, and has eaten enough dollars to fund some serious development at real space agencies. They're about to start getting their first major successes - and while they too have some very good people working for them, well, "Whoopee". When they've gotten several thousand designs into space hundreds or even thousands of times each, give me a call.
We've had some truly brilliant people working at places like NASA, the ESA, etc., who have achieved incredible tasks. And while one may blame the management, guess what? Decisions have to be made. I heard someone the other day criticizing NASA for embarking on the Shuttle project and treating it as junk, while glorifying the never-made Sea Dragon. Well, how on earth was NASA supposed to predict that the Shuttle's costs would increase so dramatically due to technological problems not yet discovered? What makes one think that a rocket, "built like a ship", would have *less* technical problems? In fact, when SEALAR was built based on the Sea Dragon design, its performance figures were horribly downgraded and even still it ended up with serious structural failures that led to its cancellation. And the shuttle's costs aren't actually as bad, comparitively, as many people think - ~20,000$/kg, while the cheapest launches out there, using the latest tech, are ~10,000$/kg and are not man-capable.
So give them a break, people. They're got some of the really intelligent people working very hard on an *incredibly* difficult task.

Exploring other worlds is expensive (Score:5, Interesting)
The cost of Beagle 2 varies (depending on who you ask) between 25 and 35 million pounds. Let's take an average of 30 million. The cost of the US Mars Rovers was 800 million for 2 (with savings on each because there were 2 of them). Right there is why Beagle 2 failed. Any failures in management are going to be mere perturbations on a delta-function graph - they had the best available technology, science, and equipment for the costs they could afford.
It's interesting to note that Manchester United paid 30 million for Rio Ferdinand from Leeds United (this is English Premier League Football, for those not UK based) which sort of sums up the UK attitude to space travel. We pay roughly equivalent amounts to move a footballer about 65 miles as we do to send a robot explorer to a different planet in search of life....
I think it all starts at a very early age. Sport is instinctively popular amongst kids and remains popular amongst adults. Science for kids is boring and dull (apart from Chemistry where once in a blue moon you get to blow something up).

As kids become adults, they keep their inhibitions about science

Basically all we learned is that that particular spacecraft team with that particular budget on that particular schedule cannot build a successful lander. Even then we cannot be sure, because Beagle may have just had bad luck. An identical spacecraft targeted a few meters away may have had a different result. We just don't know.

One suggestion for the loss of the craft was that the barometric altimeter, which was to deploy the parachute, was fooled by an unseasonal sand storm in the Martian atmosphere.

Since Beagle had no engines, it couldn't go into parking orbit until the storm went away.
