This really calls into question whether or not we can build these large multi year or multi generational ships for interstellar travel.

Eh, it's RT, I would take anything of theirs casting the West in a negative light with a grain of salt.

The ISS is more Russian than it is western. The West has contributed more money to it, but Russia was an essential partner and contributed most of the core technology due to their experience with Mir.

Regardless of that, while RT has its biases, do you really think they extend to a mundane article about bacteria on Mir & the ISS? It's hardly a discussion about the rightful sovereign of eastern Ukraine.

We need to get a lot better at managing ALL parts of a ecosystem before they will be viable.
