Four days after Beagle 2 was expected to touch martian soil, the European Space Agency (ESA) still has received no word from its lander. Scientists don't know whether a hardware or software failure is preventing the signal from being given, whether current detection methods are insufficient to pick up the signal, whether Beagle 2 landed off-target, or whether it landed safely at all.
