Jodrell Bank Telescope Gets No Signal From Beagle 425
tipiyano writes "Continuing the story of Beagle 2 from earlier today it seems like the hope for Beagle 2 surviving the landing at Mars is reducing as the Jodrell Bank telescope didn't receive any signal from Beagle. In the words of a mission manager, 'I wasn't too worried about the missed link with Odyssey, but it starts getting serious if Jodrell Bank cannot get a signal either'."

Jordell Bank confirms: Beagle2 is dying! (Score:4, Funny)
Yet another crippling bombshell hit the beleaguered Mars exploration community when recently ESA confirmed that Beagle2 accounts for less than a fraction of 1 percent of chances for survival. Coming on the heels of the latest Jordell Bank signal analysis which plainly states that Beagle2 has lost radio contact, this news serves to reinforce what we've known all along. Beagle2 is collapsing in complete disarray, as fittingly exemplified by failing dead last in the recent radiotelescope comprehensive signal search.
You don't need to be a Aldrin to predict Beagle2's future. The hand writing is on the wall: Beagle2 faces a bleak future. In fact there won't be any future at all for Beagle2 because Beagle2 is dying. Things are looking very bad for Beagle2. As many of us are already aware, Beagle2 continues to lose power. Red dust covers it like a river of blood. The lander rover is the most endangered of them all, having lost 93% of its core systems. The sudden and unpleasant failures of long time rover systems of traction and cameras only serve to underscore the point more clearly. There can no longer be any doubt: Beagle2 is dying.
Let's keep to the facts and look at the numbers.
All major surveys show that Beagle2 has steadily declined in survival chances. Beagle2 is very sick and its long term survival prospects are very dim. If Beagle2 is to survive at all it will be among martian hobbyist junk collectors. Beagle2 continues to decay. Nothing short of a miracle could save it at this point in time. For all practical purposes, Beagle2 is dead.

London,
Bookmakers in London were biting their nails with nervousness as Beagle 2 approached the touch down on Mars. On Tuesday Ladbrokes cut the odds on the mission discovering life there after a flurry of bets.
Ladbrokes received many large bets following successful separation of the lander from its mother ship, Mars Express, on Friday. Others too reportedly similar increase in number of bets.
Proof of life on Mars would leave the bookmaker liable for a huge payouts on wagers placed with them. Warren Lush, a Ladbrokes spokesman was quoted saying that odds on finding evidence of life on Mars were being reduced from 33-1 to 25-1 after facing a potential payout of hundreds of thousands of pounds.
He conceded that the odds did not represent the true odds on finding life on the planet but the price was shortened because of the liabilities of hundreds of thousands of pounds. " We first took money for Mars life on Mars back in 1969 and would be looking at a black hole in our accounts if Beagle 2 discovers something," the spokesman told the Times.
Colin Pillinger, professor of Planetary Sciences at the Open University and Beagle's lead scientist has not placed any bet. He feels it would be like insider trading.
Meanwhile, Sir Patrick Moore writing in the Mirror said we would know after a few hours if there is some form of life on Mars, 34,500,000 miles away from us. There are craters, old riverbeds, canyons, valleys and volcanoes, the Olympus Mars being three times higher than the Everest.
The scientists are agog with the expectation that signals from Beagle 2 could confirm life forms even if it was very lowly.

Why space is expensive (Score:5, Insightful)
But let's say it cost $200 million. Let's say the Brits managed to send 5 identical models 1 year apart, and 2 worked fine. Would anyone be celebrating 2 successful landers for the price of 1 Viking? Nope, instead there would be an outcry about how the space program wastes money by destroying 3 $200 million missions.
So what do the managers do? Well, NASA had a couple high-profile disasters and a couple resounding successes. Pathfinder got a lot of ink, but NASA was held up to a lot of ridicule for its failure of the failed trips. After skipping the 2001 window for flights to Mars, in 2003 NASA & JPL sent 2 very expensive (think $400-600 million each) landers to Mars. Hopefully, both will be successful. If both fail, it may indicate that they just got lucky with Pathfinder and airbags aren't the way to go.
Oh, why did they cost so much more than Pathfinder & Beagle (keeping in mind that $400-600 million includes launch, the trip to Mars, the craft itself & the management of the program)? I'm sure it's because things were checked more thoroughly, the JPL managers were more conservative, and every problem that came up was fully addressed.
On the other hand, APL seemed to have a fairly poor approach to system architecture, as can be seen by reading the NASA inquiry into the Contour mishap [nasa.gov]. The APL investigation fixed blame quickly without making a thorough investigation. The full report dug into the cause a lot more thoroughly & made a much more likely assessment, So why is space expensive? Almost every spacecraft (as opposed to satellites or launch vehicle) is essentially designed for 1 or 2 time use, and all the parts need to work, and, as highlighted above, need to work well together. That requires real engineering work involving analysis, research, testing and comparison to heritage programs. If you want to go from 50% to 90% reliability, you probably triple your costs (at least).
I hope they find Beagle. But landing a complex science instrument on a distant planet is difficult, and occasional failure is to be expected. If someone figures out a way to do it very well & very cheap, these missions may become as routine as a satellite launch. Maybe it'll be NASA or the ESA or some small entrepreneur. Good luck to them all!

1. No space probe is truly "cheap" - it costs millions of dollars to put together even the most rudimentary probe and launch it.
2. When figuring the probability of failure of a complex system you have to multiply the probabilities of the individual parts. So if you have 10 parts which all must work and they all have a 2% chance of failure then your overall probe has a 1-0.98^10 = 18% chance of failure. If you have 100 parts which all must work it is probably worth paying the extra million dollars to make them 99.999% reliable.
Somebody else pointed out that NASA/ESA/etc depend on PR for funding. As a result, it makes more sense to spend a billion dollars a mission with a 100% success rate than $30 million with a 50% success rate (people don't consider it a waste when the mission actually works - but the cheap probes are perceived as wasting $30 million every time they crash - even though on average they only cost $60 per successful mission).

After all, Mars Express will be looking for the potential signs of the possibility life on Mars - buried water, ice and chemicals - on a planetwide scale . Beagle will only be a stationary point sampler. I'm finding it strange that all that is being shouted about is the smaller part of the mission probably failed, while the greater whole is more or less working as planned.
I'm not arguing that surface lander is not useful, just that it is not the main focus of this mission. We still have two shots at landers - and these are rovers, not stationary samplers, arriving soon:

The lattest flares were among the most powerfull ever recorded, so I wouldn't be surprised if Beagle2 systems were affected by the sudden storm of magentically charged particles that came from the sun. Theoretically the probes where supposed to be magnetically shielded against these things but the strength of these lattest flares was way over what is normally expected.
There are a number of possible reasons to why we are not getting any transmissions from it. It's possible that the landing system didn't deploy properly or even at all, or the main system is malfunctioning or simply not working at all as it should after the landing. The probe could have also landed too far from the expected landing site due to the infamous martian storms that plage the planet from time to time or landed in a rocky area and when it opened a boulder may have tilded the radio dish the wrong way.
Mars Express, the orbiter, has yet to reach a stable polar orbit, as it is currently on a very eliptical orbit, but as soon as it does it will use it's high definition cameras to try and locate Beagle2 on the surface. But that's is going to take a while. Until then either we get some kind of message from Beagle or we'll just have to wait.
