Beagle 2 Probe Lands; No Signal Received Yet

securitas writes "The BBC reports that Europe's Beagle 2 Mars lander has failed to broadcast its landing confirmation signal. While project leaders are trying to put a brave face on it, the failure is seen as a major setback. The Beagle is out of broadcast range but another contact attempt will be made later today, when they hope a signal will be detected. Another failed Mars mission will solidify Mars' reputation as a spacecraft graveyard. More at icWales and News24."

It had the unfortunate experience of trying to put a lander on Mars in a completely automated manner right in the middle of one of the worst planet-wide dust storms to hit the planet and the probe never functioned properly after landing. We were very fortunate that the two Viking landers and Mars Pathfinder landed on Mars during periods of benign weather on the planet.

That allowed NASA engineers to carefully look at landing sites with the orbiter cameras to find a safe landing spot.

      Here you do have a point, but I'll argue its simply because back then a hard drive was so expensive to make that they made them to last ("What do you mean this $1,000 HD died after a year?!?"). Today's hard drives are definately built cheaper, partially because they're cheap enough that people don't mind replacing them, and partially because we've been conned into believing that hard drives are disposable. OTOH, you can buy higher quality hard drives for a higher price, and they too will last longer.

No mystery though, its the same concept: if you pay $2000 you expect it to *last*, you pay $150 (what I paid for my newest laser printer) you really can't reasonably expect it to last so long.
