This studio model of an interstellar space ship was used in the filming of the science-fiction television series, “Star Trek.” Many of the series’ 78 episodes dealt speculatively with the problems and results of human contacts with extraterrestrial life forms and civilizations. The model of U.S.S. _Enterprise_ was designed by Walter M. Jeffries and Gene Roddenberry. The model is from Paramount Television, a division of Paramount Pictures. Length 3.4 m. (11 ft., 3 in.) Diameter of disc 1.5 m. (5 ft.) Goddard A-Series Rocket, 1935 [Illustration: 20. Dr. Goddard in his workshop at Roswell, New Mexico, October 1935.] Robert Hutchings Goddard, the American rocket pioneer, was one of the first to suggest the use of the rocket to gather scientific information from high altitudes. As seamen use sounding lines to measure the depth of unknown waters, so scientists use sounding rockets to investigate the nature of our atmosphere. As early as 1917, the Smithsonian Institution agreed to fund Dr. Goddard’s studies. In 1926, he built and flew the world’s first successful liquid-propellant rocket which rose to an altitude of 12.5 meters (41 feet) over a field in Massachusetts. After the scientist received substantial grants from the Daniel and Florence Guggenheim Foundation, he established a facility near Roswell, New Mexico, where he built and tested a series of rockets and engines between 1930 and 1942. A-Series rockets—one on exhibit—were flown during the summer of 1935, as part of Dr. Goddard’s program to develop methods of stabilizing his rockets in vertical flight. The principles he pioneered in this area were among his greatest contributions to the field of rocketry. The greatest height reached by an A-Series rocket was about 2130 meters (7000 feet) and the greatest speed in flight was more than 1130 kilometers per hour (700 miles per hour). The rocket on exhibit is from Robert H. Goddard. Length 4.7 m. (15 ft., 6 in.) Diameter 15.2 cm. (6 in.) Fuel Gasoline Oxidizer Liquid oxygen Thrust about 90 kg. (200 lb.) Velocity 1130 km.
