Hopping in hypogravity—A rationale for a plyometric exercise countermeasure in planetary exploration missions

Planetary Exploration Using Hopping Robots

The recent trend towards small and frequent space mission to Mars and other celestial bodies such as moons, asteroids, and comets has sparked new interest towards multi-functional vehicles, capable of providing excellent mobility to dedicated scientific packages. Currently, the only deployed, and actively engineered, mobility paradigm is a 6-wheeled rover, as seen in the Pathfinder mission's So...

Autonomous Tier-scalable Reconnaissance Missions for Remote Planetary Exploration

A “tier-scalable” paradigm integrates multi-tier (orbit⇔atmosphere⇔surface/subsurface) and multi-agent (orbiter(s)⇔blimps⇔rovers, landers, drill rigs, sensor grids) hierarchical mission architectures [1-4], not only introducing mission redundancy and safety, but enabling and optimizing intelligent, unconstrained, and distributed science-driven exploration of prime locations on Venus, Mars, Euro...

Flight System Autonomy Needs for Planetary Exploration Missions

There is a general realization within NASA that “onboard autonomy” is needed. Exact specifications of what that means are often vague at the onset of the mission design process. Moreover, autonomy technology is generally not well understood by the spacecraft design community, which complicates matters considerably. The work described in this paper is an effort to better define the autonomy need...

passivity in waiting for godot and endgame: a psychoanalytic reading

this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
