This is similar in style to the previous book of science fiction tables: a series of d100 tables with brief phrases or one-liners, no details or descriptions.
Laboratories: The Lab Experiments table is useful for tipping off the PCs that something interesting is in the works. It might also be odd, disturbing, or alarming in some way. Items in a Biology Lab and Items in a Chemical Lab both give you ways to roll up assorted stuff. I wouldn't roll up piles of stuff for every drawer, cabinet, or room the PCs open -- boring! Instead, I'd pick one or a few things that are prominent or noteworthy and that are signficant for moving the situation along.
Cargo & Trade Goods: Three d100 tables give you cargo contents; it's similar to Items in a Cargo Hold from the previous collection. As I noted above, I'd use this only to help pick out one or a few significant, noteworthy items, instead of rolling up every a complete cargo every time the PCs run into one. A few tables give you a name (but no description) for exotic cargo items: Fictional Trade Goods, Fictional Spices, Fictional Medications. The Cargo Weight table is useless for me; each entry is a number of metric tons -- meh. Think of your favorite science fiction movies, novels, and TV series; I'll guess that the precise cargo tonnage was never interesting or relevant.
Encounters & Adventure Ideas: The tables are Space Hazards, Asteroid Belt Encounters, and Adventure Ideas. These are good news if a brief phrase or a one-liner is enough for you to work with. You could use these to create hooks or challenges, in advance or during play. If you're looking for more detail or structure, you'll need another resource, in addition to or instead of these tables.
Reasons a PC is Absent: not relevant for me. For one thing, the table fills a niche that doesn't apply in our group, because we still bring characters along if a player is absent at the moment. I could have used this table for a player's extended absence, or for explaining why an NPC isn't currently available, except that the entries are generally silly, trivial, and/or short-term, such as "stuck in a lift" or "flash mob blocking the way."
Technobabble: The two Technobabble tables combine to give you entries like Temporal Osmosis or Cotyledon Omega. It's up to you to figure out what the results mean.
Alien Names: meh. You get 200 pregenerated names and an assumption that one table fits all aliens. There are plenty of apostrophes, if you like the overused trope that science fiction editors warn writers away from. I'd be more interested in a "generator generator" that helps you create a distinct name generator for each species you need.
100 Corporate Names, 300 Planet Names, 300 Ship Names: handy lists of pregenerated names.
