Mars Probes And Failures

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:

1960
Marsnik 1 (Mars 1960A) - 10 October 1960 - Attempted Mars Flyby (Launch Failure)
Marsnik 2 (Mars 1960B) - 14 October 1960 - Attempted Mars Flyby (Launch Failure)


Marsnik 1-2

1962

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.
