The article does make the effort to scotch interstellar panspermia, but it is also possible panspermia remains a convenient idea to planetary exploration advocates.
"For a start, there's pretty good evidence that at least some kinds of bacteria and archaea – and perhaps simple eukaryotes too, a protist for example – could survive a journey between Mars and Earth, inside a rock blasted off by a meteorite impact."
So where is this 'pretty good' evidence? Actually there is no positive evidence for this. There may be better evidence that prolonged exposure to a space environment is a good way to sterilise stuff.

Ever heard of "Conan the Bacterium?"
Deinococcus Radiodurans is quite the resilient extremophile, and a good candidate for space travel.
Tardigrades, or "water bears," too, appear to be capable of surviving space travel.
