Has man already been to Mars since the 70's?

From AboveTopSecret.com:

"I was emailed this video by my brother who lives in Canada. He told me that is shows (so he was told) a joint US/Russian expedition to mars in the late 1970's. When I asked him where he got this video, I expected him to say some "friend of a friend of a friend nonsence", etc. But he said a colleague of his downloaded it off some russian video site only 2 days ago. I have taken the liberty of creating a Youtube account and uploading this video so that I can get some input on this, as if this is proven to be real, there is going to be some serious questions to answer."
