I liked checking that website, until it listed the Artemis II crew for weeks after they came back. Now I have no idea how accurate it is; I don't know what other source to compare it to.

But maybe there's a more reliable method it uses for tracking the ISS astronauts, and the Artemis II needed more human input or something. For what it's worth, both websites currently list the same ten astronauts.

Yeah you're not wrong. I've updated this site by hand since 2009. There's not one data source so for a long time I was that data source. I'll be honest: I got kind of soul-crushed when Bezos and Elon started sending people up in a way that just started to feel really dirty to me. Honestly I hated updating the site, then having to update it again an hour later every time Bezos sent someone up. It's only been in the last year that I've started keeping it current.
