@luciaceePeople laughed when Dr. Robert H. Goddard said a rocket could fly through a vacuum. His first attempts with solid and liquid propellants mostly blew apart on the pad or hopped a few feet. Years of quiet, cash-starved tinkering followed, and then on March 16, 1926, a rocket he called Nell climbed roughly 41 feet and stayed up 2.5 seconds. That's not much airtime, but the patents and methods behind it became the blueprint every modern rocket still follows

The image features a diagram of a rocket on the left and a black and white photograph of a man on the right. The man, Dr. Robert H. Goddard, is looking down and appears to be working on some equipment. The diagram is detailed with labels for various parts of the rocket. The overall style is educational and historical. The text overlay reads: "Dr. Robert H. Goddard launched the world's first liquid-fueled rocket on March 16, 1926." At the bottom right corner, there is a watermark that says "WORLD OF SCIENCE".
