Thee Harbinger

It is the year 2278 and humans are about to send the very first dispatch spaceship to Neptune.
The earth has long since been polluted, they have lived in the apocalyptic ages for way too long. It's as though man is reverting to his primitive beast era, the more technology advanced. Life on earth is shit. Those that could afford it become part of the government program that carried humans to other planets. There are human settlements on Mars, the moon, even Saturn and Jupiter were scientifically made solid and more habitable.
And on these new settlements, man's beastliness and greed still find ways to prevail, that there is now need for creating new planetary settlement. Hence, the Harbinger led by none other than Jeremy Manx would be sent to Neptune, which the scientists have found to need a few tweaks to be able to support human life, to scout the planet and ready it for settlement.
A journey that despite the advanced technological developments on the speed of the spaceship, would still last for a few years. A few years before they get to the planet, with no idea what to expect.
