Beagle: You get what you pay for...
Seems every mention of the Beagle's likely demise has a comparison of its small budget to the much more expensive and so-far successful MER mission. It was a good try by the Euros, and should be realized that it was an adjunct to the primary mission of the Mars Express, not the other way around. The problem is, a rookie landing attempt with corners being cut (ie., especially in testing and lack of system redundancy) is clearly bound for failure in a historically hostile environment that Mars is. This is the surprise in seeing the relative naivete' of those who planned Beagle. For it to succeed would have been incredibly lucky; clearly something that would have to beat very long odds. I hope the Euros will attempt another lander in the future, but that a realistic budget be allocated the next time around, or not try at all. |

A successfull Beagle mission would have been very embarassing for NASA. Can you imagine a home run on the first try. I would have been exceedingly embarrasing if Beagle had found traces of (ancient) Martian life. That would have led to some very rigorous questioning by U.S. lawmakers, no doubt. NASA got off lucky this time. Next time, the Europeans may well get something down on Mars intact. |

It was a good try by the Euros, and should be realized that it was an adjunct to the primary mission of the Mars Express, not the other way around. Of course, this realization would require a basic rewiring of the human spirit--as should be obvious from comparing the web hits after the last two successful martian orbiters vs. the current lander. If ESA would just take a casual glace at what the salary paying public really wants out of a space program, it should be obvious that Mars Express will be judged by the public on the basis of its failed lander, not its successful orbiter. We care if we can see ourselves there. Mars Express: great for science, ho-hum for the public. Beagle, if successful, would have been huge for ESA and the UK. Instead, it's a ho-hum failure. And thousands of European children are currently logged online to check out the latest from. . . NASA. Gee, where do you think the next budding Michael Foale will chose to live? Tom Merkle |

Right, like with Stardust, that complete failure of a mission that's put the final nail in the coffin of the Discovery program (among so many other failures in that ill-advised program). I say, we should take all the money in NASA's annual budget and save it up for 20 years and then launch a combo manned / robotic flyby and rendezvous mission to every body in the solar system with a diameter larger than 1,000 km. If more money is always better then ALL the money in one gigantic mission has to be the best possible plan. |

The simplest and best way to add redundancy, though, is to launch more than one spacecraft. Note that I, among many others here, warned that success for Beagle 2 was unlikely, precisely because of its complete lack of backup systems. The success rate for non-redundant spacecraft has actually been fairly good of late. Notably, there was little redundancy on Mars Pathfinder. (And yes, lots of people within JPL were saying it was bound to fail... which probably helped it, by making the Old Guard bureaucrats keep their distance.) How can you provide a probe like Beagle 2 with, say, a redundant airbag system? The answer is, you can't. Electronics is the only area where it's really *easy* to provide redundancy, and modern electronic systems are extremely reliable even without it. Their failures are mostly design errors, which redundancy is little protection against. Most of the places where redundancy is easy don't really need it much any more; most of the places where it's really needed, either it's very difficult to provide or the failure modes are such that it may not help much (having a redundant propulsion system would not have saved Mars Observer, even though that's where the failure was). -- MOST launched 30 June; science observations running | Henry Spencer since Oct; first surprises seen; papers pending. | |
