Pretty cool story. And not a hoax at all. Both the people mentioned in the article, Chandra Wickramasinghe and Milton Wainwright, are real scientists who are working to try and prove their hypothesis of panspermia using the scientific method (unlike most the idiots on the History Channel).
That said, it has NOT been confirmed that this is organic material nor that it is of alien origin. The standard of evidence for proving the existence of alien life is going to be very high. I personally am going to withhold judgment until they publish a peer reviewed scientific paper on their findings. And even then, I will continue to be highly skeptical until a group of outside researchers is able to look at the material and reach similar conclusions.
All my caveats aside, it would be awesome if we find out this is actually alien life! SETI and NASA would surely get a huge bump in their funding.
