In the year 1970, the Venera 7 probe landed on Venus, and atmospheric readings revealed the atmosphere to be similar to Earth, with an atmosphere of 77% Nitrogen, 22% Oxygen, and 1% other gases. Mars' atmosphere, which was found to be almost as strong as Earth's, was similar, with 79% Nitrogen and 20% Oxygen (1% other gases).
As more pictures were taken and more probes landed, Mars and Venus were discovered not only to possess magnetic fields, but to have large ocean ecosystems and some plant life, though most lifeforms on both planets are microscopic and no sapient creatures were discovered on either planet.
Throughout the twenty-first century and beyond, Earthly powers aimed to conquer these new worlds, while still maintaining a grip on their Earthly lands. Beyond these planets lie Mercury and the gas giants, along with their moons, who's previously untapped resources are highly coveted by various factions.
Now, it's the year 2500, the dawn of the newest century, almost nothing is predecided, so what happened in that time will be decided by you. Every 4 pages of IC is one year.
It takes around 30 days for most spacecraft to reach Venus, and 50 to reach mars.
Rules
Realism
Just because the RP is set in space doesn't mean there's going to be intersolar travel or anything like that. The date at which you can alter history is 1946.
Country size
You don't own any of the main three planets, end of story. Similarly, you don't own any entire continent. Martian/Venusian countries may be somewhat larger than Earth ones given that they would face little opposition in expansion, but they still can't be overly gargantuan.
Originality
Don't steal content from other franchises, enough said.
