Wreckage of Beagle found scattered in Mars crater
Talk about being unlucky assuming this is confirmed. |

Hmmmm...
So there was no error or malfunction of the lander. But it seems that landing into hollowed places is not uncommon. Imagine it had landed a bit more to the right, in the larger crater... rolling all along the slope, to end up bogged into a dune in the bottom. This is, I think, a lesson to retain: we cannot design landers able to land only into ideal flat places. The landers must be able to land into harsh places, including craters and slopes. |

The landing guessing cost is rather too high so it is rather convenient to invest more the intelligent landing technology in order to minimize the misfortune. Consequently the overall will lead a lower mission cost. Long time ago, in the Skycrane topic I have discussed about the importance to incorporate a sophisticated software to analyze the landing image and mark a CROSS or zone for the best landing place. That is a new and the next technology evolution. The aim for all next spacecraft landing in any solar system must have incorporated the landing software. Up to now, all spacecraft has landed by the luck. None of them have analyzed the surface and select the place before landing. Some probe very lucky (Huygens) and some very bad luck (Beagle2).

Rodolfo Newest image analysis could allow today for real-time 3D analysis of the terrain, provided there is a camera aboard (two wiews of the same spot make a stereo view, as a probe seldom lands vertically). This is done for most modern homing missiles which go much faster than a probe... |
