Who is NASA funded by?

In the realm of space exploration, NASA stands as a beacon of innovation and discovery. But behind the dazzling missions to distant planets and the cutting-edge research, there lies a question that often piques the curiosity of the public: Who funds NASA? After all, the tasks undertaken by NASA are not only incredibly complex but also incredibly costly. Do the funds come primarily from the federal government? Are there private donors involved? Or perhaps a combination of both? Understanding the funding structure of NASA is crucial in gaining a deeper insight into how the organization operates and what drives its ambitions for the future.
