1. SATURN -- Visitors who enter Space Park from the Ford Building pass under the business end of the five-engine S-1C stage of the three-stage Saturn V, which will propel American astronauts toward the Moon. This boattail alone stands 51 feet, but when fully assembled with the Apollo Command, Service and Lunar Excursion Modules mounted on top, Saturn V will be some 365 feet tall. Thrust: 7.5 million pounds (compared with 367,000 pounds for the Atlas, which launched Mercury astronauts). TOP

2. APOLLO -- Two of the three parts of the moonship are shown in this full-scale model: the Command Module (11 feet long, about 5 1/2 tons), which will carry the crew of three as well as guidance and control instruments; and the Service Module (23 feet long, about 25 tons), which holds main propulsion elements. TOP

3. LEM (for Lunar Excursion Module) -- This is the third major part of the Apollo craft, a full-sized model of "the Bug" in which two of the three astronauts will land on the Moon. A film depicts the Moon mission. TOP

4. HEARTBEAT SENSOR -- Visitors can see their heartbeat measured on this display explaining how biological sensors monitor physical state of men in space. TOP

5. TITAN II -- As seen in Space Park, with the Gemini spacecraft in place for launch, Titan II stands 109 feet tall and is 10 feet in diameter. Basically, it is a two-stage 90-foot booster developed by the Air Force. Its first stage develops about 430,000 pounds of thrust at sea level; its second stage, about 100,000 pounds at altitude. With two large solid-fuel rockets strapped on and a liquid-fuel third stage, it becomes Titan III-C, which stands 103 feet tall and can develop about 2.5 million pounds of thrust. TOP

6. GEMINI -- the two-man Gemini spacecraft externally resembles the one-man Mercury but is wider at the base (6 feet vs. 7.5), taller (10 feet vs. 11), and heavier (3,200 pounds vs. 7,700). It also has docking apparatus for connecting with another vehicle in space -- i.e., the Agena -- and, instead of an escape tower like the Mercury, has ejection seats. TOP

7. MERCURY SPACECRAFT -- This is the actual Aurora 7 in which Astronaut M. Scott Carpenter orbited the Earth three times May 24, 1962. It is about 6 feet across the base, 10 feet tall, and weighs 3,200 pounds. TOP

8. MERCURY SPACE RIDE -- Here's a chance for the kids -- and father, too, if he has the urge -- to take a simulated trip into space in a full-scale animated Mercury spacecraft. Climb in, push the button, and the countdown begins for an up-and-down ride made realistic by colored film of the Earth as it looks to an astronaut from 100 miles up. TOP

9. ATLAS -- As shown in Space Park, with the Mercury spacecraft in place, Atlas stands 92 feet tall. The basic launch vehicle, developed by the Air Force, has three liquid propellant engines developing about 367,000 pounds of thrust, stands 69 feet tall and measures 16 feet across the engine nacelles and 10 feet across the tank section. With Centaur as a second stage, Atlas can rocket a 1,300-pound spacecraft to Venus or Mars or a 2,300-pound payload to the Moon. TOP

10. RANGER -- This is an exact full-scale model of the Ranger VII, which televised more than 4,000 photographs of the Moon's surface before hitting the Moon July 31, 1964. It is identical with the successful Rangers VIII and IX. TOP

11. THOR DELTA -- The full-scale booster on display, 90 feet high, has three stages and can rocket about 105 pounds to the Moon. Among 22 consecutive successful launches, it orbited Echo I, the TIROS satellites, and Ariel I. The Thor booster, which develops 172,000 pounds of thrust, also is used in Thor Agena, a two-stage 76-foot-tall rocket, and the thrust-augmented Thor (TAD), which has three Thiokol solid-fuel engines mounted around the base and develops 332,000 pounds of thrust. TOP

12. EXPLORER I, the first U.S. satellite to achieve orbit, was launched by the Army January 31, 1958, from Cape Kennedy, and is generally credited with discovering the Van Allen radiation belt. It was launched by a four-stage Jupiter C. TOP

13. OSO (for Orbiting Solar Observatory) is a series of satellites like the full-scale model shown. Purpose: to study the Sun and its atmosphere. Also displayed are 1/8-sclae models of OGO (for Orbiting Geophysical Observatory) and OAO (for Orbiting Astronomical Observatory). TOP

14. MARINER II -- It was a spacecraft like this full-scale model which on December 14, 1962, flew within 22,000 miles of Venus and made scientific observations of that planet and the region of space between Venus and Earth. TOP

15. NUCLEAR TEST DETECTION RESEARCH SATELLITES, like that shown in full scale here, are being used to design world-wide detection systems. The Air Force launched two such spacecraft, five feet in diameter with 14,000 solar cells to power their 40,000 electric components, with the same rocket and put them into separate orbits. TOP

20. DISCOVERER XIV, first U.S. satellite recovered from space by an aircraft in flight, was snared by an Air Force C-119 flying 8,000 feet over the Pacific southwest of Hawaii August 19, 1960. The 300-pound satellite, launched by a Thor Agena from Vandenberg Air Force Base, fired retro-rockets after 17 orbits, and a parachute lowered it into the recovery area. TOP

21. TELSTAR I, launched July 10, 1962, was the first communications satellite to handle all types of signals, including black-and-white and color television. Telstar II was launched May 7, 1963, and though, like Telstar I, was launched by NASA, had all costs paid by the American Telephone & Telegraph Co. as a step toward developing commercial satellite communications. TOP

22. SYNCOM, for Synchronous Communications, is a satellite orbiting 22,300 miles above the Equator at a speed which makes it appear motionless from the revolving Earth. Syncom II launched July 26, 1963. Syncom III was launched August 19, 1964. TOP

23. ECHO II, this highly visible inflatable 135-foot sphere of 0.00035-inch Mylar sandwiched in 0.0002-inch aluminum foil, was put in orbit January 25, 1964. The passive reflector communications satellite has been seen by millions of people worldwide. TOP

24. NIMBUS, an advanced weather satellite that demonstrated the feasibility of around-the-clock cloud-cover photography from orbit. Nimbus I, launched August 28, 1964, sent back High Resolution Infrared Radiometer (HRIR) pictures by night and APT (Automatic Picture Transmission) pictures by day. TOP

One TV camera system can photograph more than 600,000 square miles at a time; the other, more than 200,000 square miles. TIROS VIII tested the Automatic Picture Transmission (APT) system, which sends cloud-cover photos to relatively inexpensive (about $300,000) mobile ground stations. TOP

26. BIOSATELLITE - A series of six biosatellites will be put in near-Equatorial orbits, starting in 1966, at altitudes of 180-200 miles for three to 30 days to investigate the effects of weightlessness, space radiation, and changes in day-night rhythm on such living things as laboratory animals, plants, cells, and tissues. Purpose: to see how long-duration space flights might affect men. TOP
