Hohmann Transfer Orbit burn.
Weeks later, the world enters on high alert.
August, 2027. The Visitors enter Cislunar space and reports of space engagements between the unmanned orbital defences on the Moon and Earth's few manned space force assets are received on Earth.
The next day, contact is lost with the Lunar defences. Earth realises that they are at war.
August 17, 2027. Three days after the disastrous defence of Luna, Earth's orbital defences are knocked out of commission, while railguns bomb major cities and most military air bases across the globe.
Four hours later, the Visitors deploy ground troops to the targeted cities, which pre-Invasion hosted more than 1,000,000 or more inhabitants.
Within hours, they are emptied of human life. For the next four days, the armies of the world try and fail to stop the Invasion.
By the 21st of August, civilisation has collapsed and 3.9 billion are dead.
Out of a population of 8.3 billion.
2.3 billion more would die of other causes, mainly starvation, disease, dehydration, other desperate survivors, etc.
By the 22nd, a global puppet government is established called the Global Prosperity Initiative or GPI for short.
Meanwhile, Earth's remaining military forces, local militias and guerrilla groups begin their efforts to fight a guerrilla war over the next ten years.
In 2037, however, another group of Visitors, these ones with the intent to liberate the occupied Earth are spotted by the Visitors as their rivals begin their deceleration burn.
The initial invasion force in the coming months is later struck by a silent coup, as the original leaders are executed by expelling them out of the airlock, and the new leadership begins the nuclear bombardment of Earth.
As they do so, they begin to use the drones to hunt down the survivors and eliminate the remaining 2.1 billion humans that were alive prior to the nuclear bombardment.
By 2041, the last humans were exterminated, though friendly Visitor forces had begun their campaign for control of the Solar System.
Unfortunately, they are repulsed by the initial force's local assets, and as the years pass, they colonise the Earth.
37,000 years later, the Voyager 2 probe is recovered just outside of the Ross 248 star system; specifically in its Oort Cloud.
After weeks of study, these Visitors, whom have never even known humans existed up until this point, finally play the Voyager Golden Record and the series ends.
