It a funny thing but we seem to have lost quite a disproportionate
amount of probes to the planet Mars. True some of them made it, but
most don't. Lets look at the missions:

Spirit and Opportunity Probes look the same
If you read the list you will have to notice that 21 attempts to
land on Mars or send orbiters around Mars have failed. And only
14 succeeded. Of these l4 some were only flybys and some were probes
to the moons of Mars. Conspiracy theorists are saying that there
is something on Mars that we are not being allowed to see. But how
do they account for the successful landings and orbiters? They state
that these are not in critical areas of the planet. But if I were
to agree with this logic I then would have to say that Cydonia is
not a critical area. For those of you who don't know about the Cydonia
region of Mars, that is where the famous 'Face' and 'Pyramid' are
located along with other things that are being called ruins.
So why are there so many failures with probes? Because
it is far away and our technology is still crude. If you notice, most
of the successes are missions launched from the U.S.. The reason for
this is that we have the most experience right now at planetary launches.
As other countries gain the experience, the rate of failure will surely
decrease. There is nothing mysterious involved with this. Lets look
at the Mars Express launched by Europe. It was supposed to reach Mars
around Christmas which it did, but its lander has remained silent. How
many landers have the Europeans landed anywhere? Shouldn't the Europeans
have perfected landing on the Moon before trying to land on Mars? Well
I guess that is a matter of opinion but I was always taught that you
had to take baby steps before learning how to walk.
