Multiple realities
(covers information from several alternate timelines)
Robert H. Goddard was a Human scientist of the early 20th century.
He was a rocketry pioneer, and, in 1926, launched the first liquid propelled rocket. His accomplishment was considered vital to the birth of the space age in 1957. (TNG: "Loud As A Whisper", okudagram; Star Trek: Enterprise opening credits)
In the mirror universe, his work led to the planting of the Terran Empire flag on Luna. (Star Trek: Enterprise "mirror" opening credits)
Prior to the release of the second season of TNG on Blu-Ray, the information on Robert H. Goddard was illegible. The text mentioning Goddard was an excerpt from Pioneer: First to Jupiter, Saturn, and Beyond (NASA Publication SP-446, 1980). The identification of this body of text was made by Jörg Hillebrand and Bernd Schneider for Ex Astris Scientia. [1]
According to the Star Trek Encyclopedia, 4th ed., vol. 1, p. 307 the shuttlecraft Goddard was "named for American rocket scientist Robert H. Goddard (1882-1945), inventor of the liquid-fueled rocket." The USS Goddard was probably named for him as well.
