What if the Challenger launch had been delayed by a single day?

In Delta-47, "Challenger Safe", the 1986 shuttle mission that once ended in tragedy becomes a national triumph. Christa McAuliffe returns from space, sparking a generation of scientific ambition and educational reform. But as one tragedy is averted, another looms. In this alternate history, we follow the ripple effects across decades—from classrooms to Columbia, from a child's dream to a nation's reckoning. This is a story of inspiration, loss, and the fragile momentum of progress.
