This is the problem with non rotation similar to our moon:

With an always-day desert on one side and an arctic hellscape on the other, any planet’s chance of being habitable looks far less likely.

However, some of our thinking may have been incorrect which has good implications:

Here comes some good news, though. A team of astrophysicists has announced that this thinking could be wrong—rotational lockup is not necessarily the rule for these exoplanets. As they report in the journal Science, the simple existence of an atmosphere (even one as thin as Earth’s) can keep a planet twirling and habitable. According to Jérémy Leconte, the theoretical astrophysicist at the University of Toronto who lead the team that made this discovery, the finding means that a large number of already discovered Earth-like planets might be a lot more habitable than we thought. “Planets with potential oceans could thus have a climate that is much more similar to the Earth’s than we’ve previously expected,” he says.

Ok with all this great news what’s next?  We just have to figure out how to get to one or more of these planets 😉
