Japanese engineering giant Obayashi claims they’ll build it by 2050, while new breakthroughs in nanotube synthesis edge closer to the impossible: materials 100 times stronger than steel cable, manufactured at kilometer lengths. The space elevator isn’t science fiction anymore—it’s an engineering challenge with a $10 billion price tag and the potential to drop launch costs from $22,000 per kilogram to just $500.
