Signed autograph manuscript drawing of the Apollo 11 Moon landing mission. [Cincinnati, n.d.
ICONIC DRAWING OF AN EPOCHAL MOMENT IN HISTORY.
Neil Armstrong, first man to walk on the Moon, illustrates key elements of the Apollo 11 moon landing in this rare drawing. He notes the rotation of the Earth, marks the “dark” side of the moon, and shows the direction of the Sun’s rays. A dashed line around the Moon indicates the command module’s path in orbit, and the curve at the lower left of the Moon shows the path of the lunar module approaching the landing site.

Typed letter signed to Michele Besso. Princeton, 14 December 1946
In this fine letter Einstein reminisces with his lifelong friend Michele Besso about their days at the Swiss Patent Office where together they developed the theory of special relativity. He likens their scientific conversations at the office to the work of God creating the world.

VON BRAUN, WERNHER
Original drawing, “3-Stage Satellite Vehicle (pitch plane)” signed and dated 1952. [Huntsville, Alabama, 1952.]
his is an original signed drawing of a space ship by Wernher von Braun, the father of the American space program. He made this drawing for his landmark Colliers series “Man Will Conquer Space Soon” (1952-54), which played a central role in inspiring a generation of rocket scientists and convincing the public of the possibility of space exploration. These essays covered seemingly every aspect of manned space flight and anticipated many developments including the enormous multi-stage vertical launch vehicle (to become Saturn V), a horizontal landing space ferry (the Space Shuttle), an orbiting space station, a lunar landing, the establishment of a base on the moon, and ultimately a manned expedition to Mars.
GODDARD, ROBERT H
Autograph manuscript diagrams and text. [n.p., n.d.],
Goddard (1882-1945), the “father of modern rocket propulsion,” launched the world’s first liquid-propellant rocket on March 16, 1926, at Auburn, Massachusetts, a “feat as epochal in history as that of the Wright brothers at Kitty Hawk” (NASA). Goddard had a rare genius for invention and these notes suggest the endless refinement necessary to create a dependable, operational rocket engine.
