The emerging field of multifunctional structure (MFS) technologies enables the design of
systems with reduced mass and volume, thereby improving their overall efficiency. It …

Supercapacitors are known for their rapid energy charge–discharge properties, often ten to
a hundred times faster than batteries. However, there is still a demand for supercapacitors …

The alkali-metal thermal-to-electric converter (AMTEC) changes thermal energy directly into
electrical energy using alkali metals, such as sodium and potassium, as the working fluid …

A need exists to protect the crew of interplanetary spacecraft from lethal doses of Galactic
Cosmic Radiation (GCR) and Solar Energetic Particles (SEPs). As plans progress to send …

Nanosatellites have the potential to carry out the complex work of today's larger satellites at
a fraction of the cost. Their small designs drastically reduce launch costs and allow many …

A method is presented for establishing and maintaining a lunar mapping orbit using
continuous-low-thrust propulsion. Optimal control theory is used to maintain a lunar orbit that …

This paper presents a discussion on sizing, weight and power of micro autonomous air and
ground vehicles. While the air vehicles include both rotor and flapper based design, here the …

Semiautonomous rover scaling is examined for exploration throughout the solar system.
Communications to a relay orbiter is a major constraint, due to power requirements and …

In the last year Israel Aircraft Industries (IAI) has engaged in the study of Proton Exchange
Membrane (PEM) based Regenerative Fuel Cells (RFC) technology for electrical energy …

Size and performance characteristic limits are discussed for government and commercial
spacecraft classes. Potential future sources of space power are described. These …
