Nutritional status assessment in semiclosed environments: ground-based and space flight studies in humans.

Adequate nutrition is critical during long-term spaceflight, as is the ability to easily monitor dietary intake. A comprehensive nutritional status assessment profile was designed for use before, during and after flight. It included assessment of both dietary intake and biochemical markers of nutritional status. A spaceflight food-frequency questionnaire (FFQ) was developed to evaluate intake o...

New concepts for Space-Based and Ground-Based Laser Weapons

Is the Department of Defense (DOD) pursuing the correct investment strategy for space-based laser weapons? Recent advances in lasers, optics, and spacecraft technologies may bring high-energy laser weapons to a sufficient level of maturity for serious consideration as space weapons against the theater ballistic missile threat. However, these technological advances also make other architectures ...

Ground-based Telerobotic Interfaces for Space Telescience

So far, Earth-based space science has been carried out from a few dedicated facilities, with scientists working away from their home institution and with limited participation of the science community to the experiments. A better approach to ground control of space experiments would consist of deploying a network of operation stations located at various institutions and connected via Internet t...

Helioseismology and Solar Abundances

Helioseismology has allowed us to study the structure of the Sun in unprecedented detail. One of the triumphs of the theory of stellar evolution was that helioseismic studies had shown that the structure of solar models is very similar to that of the Sun. However, this agreement has been spoiled by recent revisions of the solar heavy-element abundances. Heavy element abundances determine the op...
