Joëlle Jones fills in on art this issue–a flashback to the early oughts when the long distance space shuttle program is getting started up. Her style resembles the regular art, but there’s something different about it. She draws all of her characters the same age; they all look like they’re in their early twenties.
So it looks a little like “Beverly Hills 90210,” because they’re all devastatingly good looking too.
Soule splits the issue between two characters; frankly, if they’re in the current timeline on the series, Soule’s not doing a good job establishing his characters because they seem totally independent from the series so far. Maybe the cast just isn’t memorable enough.
One of them is an anthropologist or archeologist with personal problems, the other is a geologist with debt problems. It’s not an exciting issue but Soule successfully maintains Letter 44 as realistic sci-fi. It’s thoroughly solid filler.

I believe this was a fill in, and that the fill in issues were going to be about the astronauts, two at a time?
They didn’t seem familiar…
