The Earth Observing System

The restructuring of the NASA Earth Observing System (EOS), designed to provide comprehensive long term observations from space of changes occurring on the Earth from natural and human causes in order to have a sound scientific basis for policy decisions on protection of the future, is reported. In response to several factors, the original program approved in the fiscal year 1991 budget was restructured and somewhat reduced in scope. The resulting program uses three different sized launch vehicles to put six different spacecraft in orbit in the first phase, followed by two replacement launches for each of five of the six satellites to maintain a long term observing capability to meet the needs of global climate change research and other science objectives. The EOS system, including the space observatories, the data and information system, and the interdisciplinary global change research effort, are approved and proceeding. Elements of EOS are already in place, such as the research investigations and initial data system capabilities. The flights of precursor satellite and Shuttle missions, the ongoing data analysis, and the evolutionary enhancements to the integrated Earth science data management capabilities are all important building blocks to the full EOS program.

Creating new opportunities for communicating about space science

With the political and economic atmosphere changing so drastically, NASA has found it necessary to change its mission from one of exploration to that of accountability and application. These changes have made it difficult for NASA to access how its roles and constituency groups have changed in response. Specifically, at the MSFC Space Sciences Lab, management must now decide the most appropriate communication objectives, strategies and target market to direct messages reflecting these changes. Complicating the issue is that MSFC, must walk a fine line between looking as though it is spending too much money and 'marketing' themselves, which it is strictly prohibited from doing, and imparting the information in an exciting enough form to be picked up by the media.

NASA/DOD Aerospace Knowledge Diffusion Research Project. Paper 62: The Influence of Knowledge Diffusion on Aeronautics Innovation: The Research, Development, and Production of Large Commercial Aircraft in France, Germany, and the United Kingdom

This paper focuses on how European public policies-individually and collectively - influence the diffusion of knowledge and technology. It begins with an overview of the roles played historically and currently by European governments in the research, development and production (RD&P) of large commercial aircraft (LCA). The analytical framework brings together literature from global political economy, comparative politics, business management, and science and technology policy studies. It distinguishes between the production of knowledge, on the one hand, and the dissemination of knowledge, on the other. France, Germany, and the United Kingdom serve as the analytical cases. The paper concludes with a call for additional research in this area, some tentative lessons learned, and a discussion of the consequences of national strategies and policies for the diffusion of knowledge and technology in an era of globalization.

Automated Pollution Control

Patterned after the Cassini Resource Exchange (CRE), Sholtz and Associates established the Automated Credit Exchange (ACE), an Internet-based concept that automates the auctioning of "pollution credits" in Southern California. An early challenge of the Jet Propulsion Laboratory's Cassini mission was allocating the spacecraft's resources. To support the decision-making process, the CRE was developed. The system removes the need for the science instrument manager to know the individual instruments' requirements for the spacecraft resources. Instead, by utilizing principles of exchange, the CRE induces the instrument teams to reveal their requirements. In doing so, they arrive at an efficient allocation of spacecraft resources by trading among themselves. A Southern California RECLAIM air pollution credit trading market has been set up using same bartering methods utilized in the Cassini mission in order to help companies keep pollution and costs down.

The Neurolab mission and biomedical engineering: a partnership for the future

Over the last five years, with the advent of flights of U.S. Shuttle/Spacelab missions dedicated entirely to life sciences research, the opportunities for conducting serious studies that use a fully outfitted space laboratory to better understand basic biological processes have increased. The last of this series of Shuttle/Spacelab missions, currently scheduled for 1998, is dedicated entirely to neuroscience and behavioral research. The mission, named Neurolab, includes a broad range of experiments that build on previous research efforts, as well as studies related to less mature areas of space neuroscience. The Neurolab mission provides the global scientific community with the opportunity to use the space environment for investigations that exploit microgravity to increase our understanding of basic processes in neuroscience. The results from this premier mission should lead to a significant advancement in the field as a whole and to the opening of new lines of investigation for future research. Experiments under development for this mission will utilize human subjects as well as a variety of other species. The capacity to carry out detailed experiments on both human and animal subjects in space allows a diverse complement of studies that investigate functional changes and their underlying molecular, cellular, and physiological mechanisms. In order to conduct these experiments, a wide array of biomedical instrumentation will be used, including some instruments and devices being developed especially for the mission.

A consensus approach to planetary protection requirements: recommendations for Mars lander missions

Over the last several years, the nature of the surface conditions on the planet Mars, our knowledge of the growth capabilities of Earth organisms under extreme conditions, and future opportunities for Mars exploration have been under extensive review in the United States and elsewhere. As part of these examinations, in 1992 the US Space Studies Board made a series of recommendations to NASA on the requirements that should be implemented on future missions that will explore Mars. In particular, significant changes were recommended in the requirements for Mars landers, changes that significantly alleviated the burden of planetary protection implementation for these missions. In this paper we propose a resolution implementing this new set of recommendations, for adoption by COSPAR at its 30th meeting in Hamburg. We also discuss future directions and study areas for planetary protection, in light of changing plans for Mars exploration.

Experiments on plants grown in space. Status and prospects

Space flight provides a unique capability to gravitational research by providing an environment in which gravity can be manipulated below the Earth norm of 1 to a state comparable to weightlessness. Although space experiments with seeds and plants have been conducted for almost 25 years, we are only now entering an era that promises the capability of routinely conducting controlled plant experiments in space. Results from experiments with higher plants and seeds flown thus far in both manned and unmanned spacecraft from both the USA and USSR are briefly summarized. An overview of the current status of space biology experimentation as it relates to plants is presented and present and future opportunities to conduct plant experiments under space flight conditions are discussed.

Plants in space

Space may be, as some have called it, our last frontier. As such, it provides novel, even unique research opportunities. Plants are sure to figure significantly in these activities. The ability to manipulate the force of gravity from near zero to 1 g affords fresh opportunities to investigate gravity's physiological effects as well as a means of probing gravi- and phototropism, thigmo-morphogenesis, and other environmental effects in a state uncompromised by gravity. In this review we aim primarily to consider phenomenology, a goal that befits the state of our knowledge from space experiments. We intend to provide grist for future ground-based and space experiments and to reveal the potential for scientific discovery in this area.

Chemical evolution and the origin of life: cumulative keyword subject index 1970-1986

This cumulative subject index encompasses the subject indexes of the bibliographies on Chemical Evolution and the Origin of Life that were first published in 1970 and have continued through publication of the 1986 bibliography supplement. Early bibliographies focused on experimental and theoretical material dealing directly with the concepts of chemical evolution and the origin of life, excluding the broader areas of exobiology, biological evolution, and geochemistry. In recent years, these broader subject areas have also been incorporated as they appear in literature searches relating to chemical evolution and the origin of life, although direct attempts have not been made to compile all of the citations in these broad areas. The keyword subject indexes have also undergone an analogous change in scope. Compilers of earlier bibliographies used the most specific term available in producing the subject index. Compilers of recent bibliographies have used a number of broad terms relating to the overall subject content of each citation and specific terms where appropriate. The subject indexes of these 17 bibliographies have, in general, been cumulatively compiled exactly as they originally appeared. However, some changes have been made in an attempt to correct errors, combine terms, and provide more meaningful terms.
