My TiVo recorded the first episodes as a suggestion, and I've found it a rather enjoyable series so far.
The science is, of course, not perfect -- for example, they give an explanation why everyone walks around (rather than floats), but that doesn't cover why their hair & other things aren't always floating
They did provide an explanation for it in the latest episode.

Overall, here's my opinion of it:
Good points:
- Interesting concept (a six-year mission around the solar system, with flashbacks to their training period)
- Lots of prominent roles for Canadian actors (Laura Harris, Christina Cox, Maxim Roy) [and regarding Ms. Roy, I think it's the first time a Quebec actor has had a regular spot on an American network series]
- Ron Livingston's character (basically a slightly depressed version of his usual schtick)
Bad points:
- Some cliché characterization (the sexpot, the nerdy goofball, the straight arrow that falls for the bad boy)
- The hidden mission with the secret cargo that reminds viewers too much of 2001: A Space Odyssey
Is it just me, or is the whole 'alien artifact' story advancing way too rapidly? It seems like it's featured in the A- or B-plot in every episode so far, and I worry that the writers won't be able to maintain the suspense for the whole season, much less the whole prospective series.
