Two of the many research areas integral making a Mars-Earth optical communication link a reality are optical antenna design and laser transmitter design. This paper addresses areas of both of these by exploring a mode-matched ...

Sample transport is an important requirement for In-situ analysis of samples in NASA planetary exploration missions. Tests have shown that powders or liquid drops on a surface can be transported by surface acoustic waves ...

We continue our study of the stability of thin isothermal bow shocks. We follow the transverse

Traversability index is introduced in this paper as a new and simple measure for traversability of natural terrains by mobile robots.
