Terra Nova is the home of NeoTech which is a militaristic organization. It has no enemy NPCs, however it does have a lot of asteroid Belts.
The New Mapping system is better, because the of the way it is set up, it has asteroid belts and nebulas that cause some damage to your ship in a period of about 10 seconds, and it dishes out 233 damage per second, so in a matter of seconds you are dead. This gives it more of a fun sense, and it is also good if you want to give other enemies more damage.
