This is an original worldbook for GURPS. It is a future history suitable for a Hard Science Fiction campaign, in the tradition of stories by Robert Heinlein, Lester Del Ray and Ben Bova, or maybe the manga/anime Planetes. Technology has moved man out into space but not out of the solar system yet. Mars is being terraformed but isn't fully habitable yet. Terradyne, a space-based corporate state, dominates but does not have exclusive control of space-based industries.
Seems to have been superseded by the Transhuman Space series which covers the same niche.
GURPS Reign of Steel: Like the future of Terminator - but Earth is controlled by lots of different AIs, not all of which want to wipe out humanity altogether...
GURPS Lite is all right for simple campaigns, but if you want to introduce some of the more exotic nonhumans, you probably want to buy GURPS Basic Set:Characters for 4E (your players won't need it as long as you carefully pick the stuff you need and discard the rest).
GURPS Space is a book on space travel and sci-fi, full of ideas and advice for playing and game-mastering as well as world building.
The actual GURPS skill level would then depend on the difficulty of the skill and whether it was a Mental or Physical skill.
This is the GURPS Mental/Average skill of Research, and his level of 3 indicates that he has spent 3 points on it, giving him a final skill of IQ (or 11).
