As the years went on, the human population was increasing more and more. New planets had to be colonized. BnL took lead of the colonization of other worlds.
2212: Population of Earth is 36.3 billion. Space research facility constructed on Deimos. Construction of first settlements on Io begins.
2250: Population of Earth is 40 billion. The moons' colonized zones are now bustling dome cities. Mars' colonized zones are also bustling dome cities.
2275: Population of Earth is 45 billion. Many new inhabitants are moved to Io, Mars and the newly colonized planets Carme and Rhea. Holographic sun screens are used on the domes' ceilings to provide heat for the plant life in these domes.
2300: BnL star liners discover a second sun far beyond Pluto. First faster than speed of light ships used to take human settlers to Kurar, a large Earth-like planet. BnL construct a large military base on Enceladus.

2472: Lupo becomes a major planet after construction of It's metropolis, Korton, is complete.
Humanity now colonizes half of Takra. Mars becomes first city planet of humanity.
2491: Largest space research facility constructed on Takra. Carme and Rhea become first planets to have underground settlements. Construction of space stations over Idlem begin.
2500: BnL begins construction of military space ships. BnL's army is given the title United Earth Space Corps (UNSC).
2515: A new planet, twice the size of Earth, is discovered. Construction of military scientific research, military and space research facilities on the planet begins. Humanity had advanced very far in technology. With many planets under human colonization, humanity looked like it was to continue It's never ending quest to discover the secrets of the universe.
