If you're looking for rules for reaction drive(chemical/ntr rockets) travel within the solar system this is fantastic. It has a good amount of realism that you could certainly ramp up based on these rules.

If like me your film libray includes such titles as "The Martian", "Star Cops", "Outland" and so on and your reading runs to Allen Steele's "Rude Astronauts" then this source book i definuitely for you. I wasn't tottally blown away by the polotics of the background but everything else was well worth it. There are things of use if you use a more standard Traveller background as the rules for TL9 space craft and working in space will be useful in any setting and it acts as a reminder of just how much adventure you can get in a system beyond the main world.
