           | in the process.
           | 
           | But then again, astronauts have been there, and the practices
           | that were used were not (could not be) completely sterile.
           | Still, this is probably a bit worse.

           | killing their tiny bacteria.

         | What would the tartigrades eat? Surely they would die off
         | eventually due to a lack of an ecosystem - no matter how hardy
         | they are.

         | The counter argument is that if the life we inadvertently leave
         | throughout the solar system thrives, that's an interesting
         | result too. This only really becomes a problem if there was
         | other life to begin with.

       | Fortunately per the article the tardigrades are sealed in epoxy
       | and dehydrated, so any concerns about inadvertently disrupting
       | some theoretical microbial ecosystem on the moon is probably not
       | founded (not that I believe there is other life on the moon
       | anyway)
