Goddard received initial financial support from the Smithsonian Institution to conduct his early rocket experiments. This funding allowed him to develop and test his theoretical concepts in a systematic manner.

Charles Lindbergh, the famous aviator, became a strong advocate for Goddard's research after witnessing a rocket demonstration. Lindbergh's endorsement helped to raise awareness and attract potential investors.

The Daniel and Florence Guggenheim Foundation provided crucial funding for Goddard's rocket research in Roswell, New Mexico. This support enabled him to assemble a dedicated team and conduct more extensive and sophisticated experiments.

Despite his groundbreaking achievements, Goddard faced skepticism and ridicule from many in the scientific community and the media, who dismissed his ideas about space travel as unrealistic and impractical. He often struggled to gain widespread recognition for his pioneering work.

After his death, Goddard's contributions to rocketry were finally widely acknowledged. He is now recognized as one of the founding fathers of modern rocketry and space exploration. The Goddard Space Flight Center, a major NASA research facility, is named in his honor.
