It's also been discussed that the elements making up the organisms might be analyzed for isotopic ratios. These are unique to each planet. If the
isotopes don't match those from Earth, then the samples are of extraterrestrial life.
We have made discoveries of bacteria at at 20 kilometers altitude, and unspecified 'microbes', probably meaning bacteria, up to 41 kilometers. The
organisms collected by Dr. Wainwright's project appear to be diatoms, or something comparable.
These are much larger, and so, much heavier than bacteria, as a rule. It would presumably be much more difficult to transport them to 27 kilometers,
or maintain them at that altitude for any length of time.
