There's far too little information in the article to judge. In such an experiment everything depends on the controlling of contamination, and there is very little about that. Also, the discussion of whether earthly life can get high in the stratosphere is totally inadequate.
Note, also, that the "Journal of Cosmology" is a joke/crank publication that no-one takes seriously, and that the authors include Chandra Wickramasinghe, who went off the deep end long ago.
