The Atacama Desert Trek: Outcomes
In June and July 1997, Nomad, a planetary-relevant mobile robot, traversed more than 220 kilometers across the barren Atacama Desert in Chile, exploring a landscape analogous to the surfaces of the Moon and Mars. In this unprecedented demonstration, Nomad operated both autonomously and under the control of operators thousands of kilometers away, addressing issues of robot configuration, communi...
متن کاملOperating Nomad during the Atacama Desert Trek
Nomad is a mobile robot designed for extended planetary exploration. In June and July of 1997, Nomad performed the first such mission, traversing more than 220 kilometers in the Atacama Desert of Chile and exploring a landscape analogous to that of the Moon and Mars. Nomad's journey, the Atacama Desert Trek, was an unprecedented demonstration of long-distance, long-duration robotic operation. G...
متن کاملScience Autonomy for Rover Subsurface Exploration of the Atacama Desert
R obotic explorers communicate only intermittently with scientists because of limited opportunities for visibility by Earth-based antennas and the growing number of spacecraft needing attention. The data rate of deep space communication is also very limited. Autonomy can significantly improve science productivity in intervals between communication opportunities. In particular, science autonomy ...
متن کاملDeveloping Nomad for robotic exploration of the Atacama Desert
Recent years have seen renewed attention to planetary exploration, and robotics is recognized as essential to many upcoming missions. In this article we describe the ongoing efforts of the Nomad Project to develop robots for planetary and terrestrial exploration. The project is developing, demonstrating, and evaluating systems capable of long-distance, long-duration missions. In 1997 this work ...
متن کاملColonization patterns of soil microbial communities in the Atacama Desert
BACKGROUND The Atacama Desert is one of the driest deserts in the world and its soil, with extremely low moisture, organic carbon content, and oxidizing conditions, is considered to be at the dry limit for life. RESULTS Analyses of high throughput DNA sequence data revealed that bacterial communities from six geographic locations in the hyper-arid core and along a North-South moisture gradien...
