These aliens were the second creatures that humans had discovered so far that could survive at least for a short period in outer space, the first one was the tardigrade. The reason they were unable to survive for an extended period in outer space was not due to the temperature difference nor atmospheric pressure, but for the lack of oxygen.
The parasitic life form born from Earth creatures required oxygen to survive as well.
