Holding On To Hope For Beagle 2 338
slasher999 writes "Scientists are still keeping their hopes up that they will be able to revive Beagle via the Mars Express mothership on 4 January. On that date the ship will be in the correct orbit and may then be able to revive the lander. Current theroies as to what may have gone wrong include the possibility that the landers on-board clock is incorrect and that the lander has been transmitting at incorrect times. Funny, I thought I heard that as of yesterday the batteries on the lander would have been depleted unless the lander had received an order to recharge its batteries."

The Beagle II is a product of the ESA. They are quite different.
While I agree that the conversion was a silly mistake to make, you really have to appreciate how staggeringly complex the undertaking of an unmanned (or manned, in fact) space flight can be. I have three relatives that work for JPL, none of which were on the team that made the error, but they all share the shame. After seeing a small part of what is involved from them, I:
1) Am glad that I do not work for NASA, and
2) Am frankly mystified that, seeing as how we are all human, any successful automated probe missions have been accomplished at all. There is just so much that has to be done *perfectly* to have any hope of even getting off the earth, let alone circling planets at precisely calculated trajectories to gather a specific "amount" of inertia to be able to get to a specific spot over a specific planet so as to be able to exercise a specific number of steps at the exact correct time in the correct order.
Complexity-wise, it is not unlike having to build a mature mission-critical operating system in five years, which has no significant bugs and whose problems are often more difficult to solve.
While it is sometimes fun to make fun of the mistakes of others, I can do no less than stand in awe of how much NASA and the ESA get accomplished with what they have. The ESA in particular, if you compare the Beagle's budget to that of, say, the Galileo project.

So, during design, the only available method of communication would be Mars Express. It was already known that for several days after landing, MEX would not be in position to talk to the lander (due to the need to change its orbit from equatorial to polar).
Thus they had to plan for the lander to stay alive and healthy on its own for at least 10 days. That is why it was programmed to automatically recharge its batteries as soon as the solar panels were unfolded and the sun would appear.

I guess I'm "unhealthy" then. So be it.
Beagle 2 was more than a "silly space probe". Like all of our other space probes meant to do basic exploratory science, which are our civilizations very first infant steps into the incomprehensible vastness of the cosmos, Beagle was alive. It was alive with the hope of the scientist who spent months designing and refining a tiny instrument aboard its manipulator arm that just maybe, this instrument after travelling millions of miles might detect the faintest trace of life, the first on a planet outside of our own. It was alive with the wonder of all the schoolkid geeks who followed the program in their classrooms that maybe someday they might be the first person to step off of a lander into a fine red dust and look out upon stark desolate vistas of the first planet humans visit outside of their own. And it was alive with the excitement of all the rest of us who followed the mission, who rooted for the underdog and thought of the possibilities that await us in the cold inky depths of space.
So maybe I'm just being "silly" but I think only beasts could remain indifferent to the nature of the universe which created them. And even though Beagle2 would have only revealed to us a tiny fraction of a dot of that universe, it likely would have increased our understanding of it by thousands of times.

It's a noisy place out there; to design for the specific case you need requires a lot of optimisation of that case versus everything else - it's not just like scanning up and down the range... if you are not spot-on the correct frequency at the correct time, you'll miss the signal.

Moreover, all of Mars is well within a Jodrell Bank beamwidth at 500 MHz, so it doesn't matter where the thing is on Mars - Jodrell Bank should see it. And it's too much to believe that operators at Jodrell Bank, Westerbork and Stanford all screwed up such a simple measurement.
