Apollo astronauts who ventured outside of the protective confines of their pressurized capsules faced a number of hazards, among them: exposure to cosmic debris, solar radiation, and surface temperatures that widely varied. The suit also needed to accommodate a wide range of motion to allow the duties of the missions to be successfully accomplished.

Referred to as the "catalyst of the Industrial Revolution," textile manufacturing helped to transform the American economy from an agricultural to a manufacturing economy. It led to transitions from human to mechanical power and from wood to metal construction. Population shifts resulted from significant numbers of people moving from rural areas to work in urban factories. The collection of tools and machinery housed at the American Textile History Museum (ATHM) represents a collection of ideas which developed during this period.

The largest rocket built at the time of the historic first missions to the moon, the Saturn V carried aloft the 45-ton Apollo spacecraft on earth orbital and lunar missions from 1967 to 1972. It also launched the 120-ton Skylab into earth orbit on May 14, 1973.

The Pegasus 3 is the earliest surviving example of the prototype engine for vertical/short takeoff and landing (V/STOL) jets, namely the Royal Air Force's Harriers and US Marine Corps' AV-8Bs. Owned by the Rolls- Royce Heritage Trust (a company-sponsored history and preservation society), the artifact is an early developmental model of the Pegasus 3 engine, the first to fly with sufficient thrust to prove the vectored-thrust concept for V/STOL jet aircraft, in 1960.

The RL-10, which served as the power plant for NASA's upper-stage Centaur space launch vehicle, was the first rocket engine to use high-energy liquid hydrogen as a fuel. It has provided precisely controlled, reliable power for lunar and planetary explorations. The RL-10 embodied numerous advanced design features, including multiple use of its fuel with the "bootstrap cycle." The RL-10 is also capable of multiple restarts in space, which enables positioning of satellites or further escape of Earth's gravity.

This propulsion wind tunnel (PWT) at Arnold AFB was the first large-scale facility for testing jet and rocket engines in simulated high-speed flight conditions. It has a unique combination of transonic (1955) and supersonic (1960) wind tunnels using a common 236,000 horsepower drive, the world's largest when built. It can achieve air speeds up to Mach 4.75 at altitudes up to 150,000 feet in its 16-foot square, removable test sections. Design engineers were Lief J. Sverdrup, John R. Parcel, Brice Smith, and Walter Cook, of Sverdrup and Parcel, St.

The 367-80 is the prototype for most jet transports. Its success was due largely to its mechanical systems, including turbine engines with thrust reversers and noise suppressors, redundant hydraulic control systems, and an improved cabin-pressurization system. Honeycomb flap panels were introduced, along with a strong, lightweight structural design that controlled fatigue cracking. These led to several innovations in aircraft tooling and manufacturing techniques.
The Dash-80 was the first commercial airliner economical enough to take the US airline industry off subsidy.

Rapid development of aircraft design in the 1930s required many related innovations, including propeller design. The hydromatic propeller by Hamilton Standard marked a significant advance over the counterweight-type, controllable pitch propeller. The first test flight of the prototype took place in 1938: the public demonstration was made by a United Air Lines DC-3 over New York City on April 6, 1938. It played a distinguished role in allied combat aircraft in World War II.
