Flight Path Precision
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...

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...

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...

Drivetrain Design, Incorporating Redundancy, for an Autonomous Walking Robot
An often overlooked, though critical, component of a mobile robot is the drivetrain. To achieve the ambitious programmatic goals of an extra-terrestrial, planetary robotic explorer, a...

An Intelligent Robotic Vehicle for Lunar/Martian Applications
This paper describes the research effort being undertaken at UA/NASA Space Engineering Research Center (SERC) towards a general-purpose intelligent robotic vehicle system (IRVS) for Lunar...

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...

The Effect of Mobile Transporter Motion on the Space Station Attitude Control System
The effect of Mobile Transport (MT) motion on Space Station stability and the performance of the Attitude Control System (ACS) using Control Momentum Gyros (CMGs) is assessed. Analysis...

A Space Station Simulation: EXEMSI '92 A Study on Confinement and Isolation of a Mixed Crew of Four during 60 Days
Manned spaceflight is entering a new era. The next period will be characterized by long duration stays in space and heterogenous crews. EXEMSI '92 was an attempt to study the human-related...

Zero-Gravity Sports Centers
One of the uses that has been proposed for fully reusable launch vehicles is `space tourism', the making of short visits to low Earth orbit by fare-paying passengers. This seems to offer...

Resource Recovery Facilities for Earth Approaching Comets
Mankind's next large resource location may be off the planet. The facilities required for mining and material processing offer interesting concepts for the development of mankind's first...

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: 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...

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 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...

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...

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...
