I am a great fan of GTA Space mod, and I was working since a lot of time on my "Stargate Odyssey" mod which is leading you on another planets with human installations (using Menyoo / Map Editor), and I tried to learn how works GTS files, just to add elements in my futur Stargate projects ... And that is the first result !
I create a new additional solar system and 4 new habitable worlds (3 planets, and one moon) in Grand Theft Space mod as "fan update".

Here is the list of modifications :

- adding of "Hawking Planet" : a rocky planet, similar to earth, a little bit smaller. No oceans, only fossil water underground. The climate is hot and dry, temperate at the poles. The air is breathable, but there is no form of life. It is the closest planet to the host star of Kepler B53 system. Here, a day is 30 hours long.

- adding of "Horus" : this is a stormy moon of Hawking planet, protected by a powerfull magnetic field. All covered by hurricanes and storms. Lots of breathing oxygen, water, oceans, but a permanent hostile climate ... The days are endless on Horus : more than 20 earth days, linked to planet P1q570.

- adding of a black hole in the background (similar to Gargantua in Interstallar movie by Christopher Nolan, which inspired this update and the original GTS mod itself).

- adding of "Douglas Planet" : this is a giant icy planet, with a solid snowy surface and atmosphere. Temperature is bewteen -20 and -164°C from equator to poles. The air is breathable, but similar to earth at 3000 meters in the mountains. The gravity is 70% of the earth, and a day is 78 hours long. No form of life detected.

- adding of a new wormhole which leads you to "Eleonore" system. A very old system with a dying red giant star, which only has a few million years left before supernova.

- adding of "Eleonora" and his ring : a giant rocky planet, with a very fine atmosphere, but breathable oxygen just on the surface. This planet was inhabited by ancient life forms that have disappeared since billion of years. No water or clouds, the climat is very cold in the night, very hot to the day. The gravity is 40% of the earth. This planet is linked to his star and one full rotation around his host star is 340 earth years long !

- fixes in some spawning points on several planets and orbits (Karoon, Neptune and others).
- new skybox texture (brighter stars) and new sun color in Kepler system.
- new texture for Karoon : the map of this planet is mainly covered by ocean, so I make a new texture, which is now an ocean planet seen from space.
- I have enable sound in space. Less realistic but seems better for in-game experience.
