Mars Is a No Return Trip
Before Earth, there was Mars.
Not the barren wasteland you've been sold, but a thriving world of rivers, oceans, cities, and technology that dwarfed Earth's current capabilities. It was the father of pyramid civilizations, a planetary beacon of advancement and then it collapsed. Not from natural disaster. From pride. From internal war. From weapons so devastating they didn't just kill they cracked the dome shielding the planet and ignited a planetary suicide.
