Air traffic delays at the four airports operated by the Port Authority of New York and New Jersey are among the most severe and costly in the nation. A study by the Port Authority proposes...

Flight Track Noise Impact Model (FTNIM): A Tool To Assess the Cost of Noise Abatement

Hovering Over the Harbor
The $600 million extension to the Hong Kong Convention and Exhibition Center features a highly sculpted roof inspired by the uplifting image of seabirds in flight, as well as a 300-ft-long...

Smooth Take-Off
Rough runway pavement can make for a bumpy flight and nervous passengers. The Port Authority of New York and New Jersey uses an advanced software package to detect and mitigate rough spots...

The Ranger Telerobotic Flight Experiment: Mission, Technologies, and Programmatics

The Return of Deep Soil Mixing
Deep soil mixing, a technique originally developed in the U.S. in the 1970s but virtually ignored because for cost reasons, is regaining acceptance here due in large part to mechanical...

Capital Facelift Takes Flight
Since 1988, one of the largest and most complex airport renovation projects in U.S. aviation history has been under way in Washington, D.C. Known as the Capital Development Program, the...

Mars Terraformation Revisited
This report is a look into the future; not only that of the solar system, but of humans. With the goal of changing Mars into a living planet, we also have to face the change of the human...

Space Stations Past, Present, and Future
The paper discusses the evolution, present state and future of space stations. Man's interest in the stars led to many inventions and the ultimate launching of the Russian satellite Sputnik,...

Space Debris
Space exploration has introduced many positive aspects, but there is also a growing problem. From huge rockets to tiny flakes of paint, space debris is cluttering a major area above the...

Spacecab: A Concept for Commercial Human Spaceflight
This paper will describe the Spacecab conceptual design and operational scenario. Spacecab is not necessarily a unique design solution but it does illustrate a design philosophy that differs...

Development of a Partial Gravity Lunar Airlock
The Planetary Projects Office (PPO) at the Johnson Space Center is developing design reference missions for human exploration of the Moon and Mars. Missions for both planets require a...

Nuclear Propulsion: Safety Measures and Concerns
Since nuclear fission was discovered, many potential uses for it have been found. One such application of fission is nuclear propulsion systems in space ships; however, the elements resulting...

Propulsion Systems for Future Space Exploration
There are many types of propulsion that are being considered for future space travel needs. These include nuclear, solar sail, magnetoplasmadynamic (MPD) thrusters, and laser propulsion...

Inter-stellar Propulsion: The Need for Speed
Interstellar travel is certainly one of mankind's next step to reach for the stars. Four ideas for interstellar propulsion are discussed in this paper: the Orion Project, Deep Space Ramjets,...

Nuclear Propulsion
In this paper, the possibilities and safety of nuclear propulsion will be discussed and explained. The main focus pertains to the efficiency and safety of this form of propulsion. Nuclear...

Propulsion Systems: Present and Future
Propulsion is the very essence of space travel. There are many types of propulsion. Each type has its advantages and disadvantages. Propulsion systems are constantly being improved just...

Switzerland: Rail Access to Airports and the Fly-Luggage System
Swissair and the Swiss Federal Railways (SBB) offer a unique service for air passengers travelling to and from their Swiss airport of departure or arrival. In conjunction with private...

Wheel Space Station for 2025
The advantages and disadvantages of three basic space station designs are discussed. These designs are a zero-gravity can like Skylab, a tethered system, and the wheel. A design of a wheel...

Reducing the Long-Term Effects of Zero-Gravity
