  • Publication of Principia

    The English astronomer Sir Isaac Newton publishes the Philosophae Naturalis Principia Mathematica. This three-volume work outlines Newton's three laws of motion as well as his law of universal gravitation and a derivation of Kepler's laws for the motion of the planets. The Principia is considered by many to be one of the most important scientific works ever written.

  • First Exposition of Rocket Mechanics

    The British mathematician William Moore publishes Treatise on the Motion of Rockets. This work features the first exposition of rocket mechanics based on Newton's third law of motion.

  • Exploration of Cosmic Space

    Exploration of Cosmic Space Russian rocket scientist Konstantin Tsiolkovsky publishesThe Exploration of Cosmic Space by Means of Reaction Devices. This is the first serious work to be published that shows space exploration to be theoretically possible.

  • First Liquid Fueled Rocket Launched

    U.S. rocket scientist Robert H. Goddard launches the first liquid fueled rocket from his Aunt Effie's farm in Auburn, Massachusetts. The 4-foot high rocket dubbed "Nell" reaches an altitude of 41 feet and a speed of about 60 miles per hour. The flight lasts only 2 1/2 seconds, but paves the way for the U.S. rocket program.

  • Rocket Club

    The Verein für Raumschiffahrt (Society for Space Travel) is formed as an association of amateur rocket enthusiasts in Germany. This group brings together many of the engineers who would eventually make important contributions to space flight.

  • First Animals in Space

    First Animals in Space
    Fruit flies become the first animals in space as a V-2 rocket is launched from the White Sands Proving Ground. Inside are several vials containing fruit flies, rye seeds, and cotton seeds. The flight reaches an altitude of 60 miles, and the payload is later retrieved intact.
