Which levels contain Failure Logs?

Some levels in Infinifactory contain so-called Failure Logs, which are 30s to 2min audio clips which provide a bit of background story. They are usually (but not always) found in the form of a dead person in a spacesuit. It appears that not every level contains such a Failure Log, but most of them do. Still, I was surprised by the scarcity of the logs in two level sets, so I was wondering if I just overlooked them or whether they really appear this irregularly.
Curiously, I wasn't able to find a complete list of the logs online, so here we go: which levels contain a Failure Log and what does it look like?
