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...
Is It Possible to Colonize Mars?
Is it possible to colonize the planet Mars? A planet that is believed to be the most clement planet in the solar system, next to Earth. Despite the fact that it is a very clement planet,...
A Space Station of Mars
While we are putting stations on the moon and in orbit in this fast changing world of growing scientific knowledge we must look past the step we are currently on to the steps beyond. The...
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...
Reducing the Long-Term Effects of Zero-Gravity
Maintaining the physical health of scientists has been a longstanding problem in space flight research. Several ideas have been proposed to solve this problem. These include creating artificial...
Surface Payload Unloading and Deployment Options for a Lunar Return Mission
While planetary exploration studies have focuses on many areas that are critical to mission success, such as landing space transportation vehicles on other planets, a preferred method...
Characterization of Emplacement Strategies for Lunar and Mars Missions
In planning missions to the Moon and Mars, a significant activity will be the delivery of the crew and necessary equipment to the planet surface to enable the mission objectives. Because...
Lunar Transit Telescope Lander Design
The lunar surface offers a unique platform for telescopes to observe distant planets. The absence of significant atmosphere provides clarity that is of orders of magnitude better when...
Global Change: Geoengineering and Space Exploration
Increased concern over the effects of global climate change and depletion of the ozone layer has resulted in support for the Global Change Research Program and for the Mission to Planet...
The Army Corps of Engineer's (ACE) Interaction with the Mission to Planet Earth Initiative
The Corps of Engineers Research and Development Directorate has identified Mission to Planet Earth Initiative as of possible interest in supporting the non-tactical missions of the Army...
A Vision for Planetary Exploration
The Space Exploration Initiative (SEI) is the latest in a series of endeavors which represent humankind's desire to expand its knowledge and sphere of influence. Throughout recorded history,...
Altering the Solar System?Landing the Moon, Mars or Venus on the Earth?Changing the Orbit, the Tilt and the Size of the Planet Earth
It is proposed to radically change the hitherto prevailing mindset of the people (and especially of the scientists) by stressing that the present setup of the 5 billion year old Orbit,...
Global Problems: Implementing Mission to Planet Earth
Serious global environmental problems are facing our generation on Earth. The decrease in ozone concentrations and the greenhouse effect have implications for all life forms on the planet....
Mission to Planet Earth: The Quest to Save the Environment
The Mission to Planet Earth is a program designed to look at the earth as an integrated system. It is an internationally supported project. It was conceived because the current methods...
A Space-Based Communications Concept to Support Mars Exploration Missions
Both the Soviet Union and the United States have expressed a desire to conduct further exploration of Mars and both sides have raised the possibility of joint Mars missions. In addition,...
What Has the U.S. Gotten Out of the Space Program�
Since the time of its creation in 1958, the National Aeronautics and Space Administration has spent billions of dollars on space activities. What has the U.S. gotten out of these tremendous...
The Professional Engineer Half a Century Hence
What will the world of the engineer look like a half century hence? Planet Earth will still be alive, though twice as crowded as Most of the world's people will be very poor...
