At the tender age of 10, I stumbled upon a revelation that reshaped my understanding of my family. My grandfather’s weathered toolbox, long thought to be a repository of mundane tools, was in fact a treasure trove of missile craftsmanship. My father’s frequent absent-mindedness, often a source of family jest, was revealed to be the byproduct of his relentless dedication to aerospace research. These two unassuming men in my household, who had always been pillars of quiet strength, were in truth the unsung heroes illuminating the cosmos. Their stories, etched in the celestial tapestry of our nation, are a testament to the extraordinary contributions of ordinary individuals. To all such silent superheroes, we extend our deepest salute — your legacy is forever intertwined with the starry river of our motherland.
