How does the shape of the nose cone on the A Series rocket compare to nose cones on nearby rockets? Top: Goddard A Series rocket; insets of Goddard holding rocket and Goddard Is it sharper, blunter, or the same? postage stamp B The window on the rocket near the nose cone. What can you see inside? ■ liquid fuel tank ■ parachute ■ computer C The vanes. The vanes/tail fins help to stabilize the rocket in flight. How many vanes are on the Goddard A Series rocket? ■ 2 ■ 3 ■ 4 ■ 6 D The nozzle(s). The exhaust nozzles squeeze gases out producing a force/thrust that pushes the rocket forward. The Goddard A Series rocket had a thrust of 900 newtons, N, (200 lbs.). Each of the three Space Shuttle engines has a thrust of 2,000,000 N (418,000 lbs.). How many nozzles are there on the Goddard A Series rocket? ■ 1 ■ 2 ■ 3 ■ 5 A Series launch COMPARE: Rockets from the 1940s and 1950s near the Goddard A Series rocket The Corporal is three times as tall as the Goddard A Series rocket with a thrust of ~90,000 N (20,000 lbs.) and a range of 120 km (75 miles). The Regulus Cruise missile is twice as tall as the Goddard A Series rocket with a thrust of ~20,000 N (4,600 lbs.) and a range of 8000 km (5000 miles). The whole Nike-Ajax missile is about twice as tall as the Goddard A Series rocket. The main part of the rocket, the sustainer, is about the same size as the A Series rocket with a thrust of 11,500 N (2,600 lbs.) and a range of 40 km (25 miles). The Poseidon missile, built by Lockheed Martin, was launched from Poseidon Missile submarines and carried a 50 kiloton nuclear warhead. It is three times the size of the Goddard A Series rocket with a range of 5280 km (3280 miles). 2 GODDARD A SERIES ROCKET ACHIEVEMENT: the first successful rocket to travel at the speed of sound — ~1000 km/h (700 mph) — and to ascend over a mile high. Fourteen launch attempts from 1934 to 1935 HOW TALL ARE THEY? The Goddard A Series rocket, the Redstone rocket, and the Shuttle orbiter are all full-size artifacts in the Museum, 1 : 1 scale. Look at the Shuttle models under the wing of Discovery. Many are 1 : 200 scale. How tall would you be in 1 : 200 scale? Divide your height in cm (or inches) by 200.

Discovery flew 39 times from 1984 through 2011 — spending altogether 365 days in space. D C E B A Inset photos left: Space Shuttle Discovery on top of its carrier aircraft, a Boeing 747, on the ground and in atmospheric flight. LOOK FOR: A The wings. Wings provide lift, so an orbiting Space Shuttle can glide to Earth. Thick wings, and special maneuvers, reduce the orbiter’s speed from 28,000 km/h (17,200 mph) at reentry to 354 km/h (220 mph) at touchdown. How are orbiter wings and airplane wings similar? How are they different? B The black tiles. Black tiles have a coating that reflects 90% of the heat. They can resist temperatures up to 1,260°C (2,300°F). White tiles resist temperatures to 649°C (1,200°F). Which areas of the orbiter are exposed to the greatest heat during reentry? C The OMS pods. The two pods are located at the base of the vertical stabilizer (tail). They contain the Orbital Maneuvering System (OMS) engines and the aft thrusters. The small OMS engines are used in space to control altitude and speed, unlike the three main engines that are used during launch. The thrusters control roll, pitch, yaw, and lateral movements. Can you find the forward thrusters on the nose of the orbiter? D The payload-bay doors. When open, the payload-bay doors reveal a large cargo space. Look behind the Shuttle orbiter at the Spacelab. Look above the orbiter at the Tracking and Data Relay Satellite. Both of these were carried into orbit by the Space Shuttle. What is the best shape for a large Shuttle cargo? ■ rectangular block ■ cylinder ■ sphere FACT The term“Space Shuttle” E The Hatch. Astronauts use the crew hatch to enter Discovery before a launch and to leave after landing. It opens refers to a whole system made up of the into the middeck cabin, the crew’s living area. The hatch is orbiter, two solid rocket never opened in space. How do the astronauts leave and return for an EVA (spacewalk)? boosters, and the external fuel 4 tank. ACHIEVEMENT: Vega Solar System Vega Solar System Probe and Probe was the first Soviet mission Pathfinder/Sojourner to have international participation from nine nations. Pathfinder was the first planetary probe to take a rover to another planet.
