The President's Vision for Space Exploration calls for human and robotic missions to the Moon, Mars, and beyond. In response, over the next two decades, NASA may spend $100 billion on new technologies and facilities that will require reliable ground communications to achieve those missions. ...

The Indian Space Research Organisation (ISRO), after missions to the moon and mars, has now set its eyes on exploring the dark side of the moon in collaboration with Japan’s Space Agency. According to the initial plans, a lunar lander and a rover built by the Indian Space Research Organi...
While to date there was only one life-detection space mission, i.e., the Viking mission to Mars, several past and present space missions have searched for organic matter, paving the way for the future detection of signatures of extra-terrestrial life. This review also reports on the in-...
Thenonlinear effectsin gases are also widely used inTHzgeneration and detection. It has been generally recognized that absorption and dispersion due tophononmodes in the solid-based THz sources and detectors result in dark areas in the measured THz spectrum; surfaces of the emitter or sensor reflec...
(EE-1, EE-5, EE-6, EE-7); faster, lower cost “Opportunity” missions to address key scientific challenges identified by the Earth science community (EE-2, EE-3, EE-4, and EE-8); and “Fast-track” missions (EE-9). Of these, only four have relevance to environmental monitoring ...
We hope to identify high-yield opportunities for future research that might better define and mitigate pharmaceutical risk for exploration missions. Medication use and performance during spaceflight Medication use during spaceflight is not comprehensively monitored, largely due to conflicting crew time ...
