Exobiology Extant Life Surveyor
''Exobiology Extant Life Surveyor'', (also called ''EELS'') is a snakebot vehicle originally designed to explore the surface and the oceans of Enceladus, a moon of Saturn. The JPL has also referred to the possibility of using EELS to explore locations such as lunar lava tubes, Mars's polar caps, and Earth's ice sheets. It uses multiple segments containing actuation, propulsion, power and, communication electronics. The segments use corkscrews to move across the ground. These corkscrews can act as propellers while underwater. , the current version (1.0) weighs approximately , and is or 10 segments long. ''EELS'' has no scientific instruments, uses stereo cameras and Lidar Lidar (, also LIDAR, an acronym of "light detection and ranging" or "laser imaging, detection, and ranging") is a method for determining ranging, ranges by targeting an object or a surface with a laser and measuring the time for the reflected li ..., and it uses a tether for power and communications.

Jet Propulsion Laboratory
The Jet Propulsion Laboratory (JPL) is a Federally funded research and development centers, federally funded research and development center (FFRDC) in La Cañada Flintridge, California, Crescenta Valley, United States. Founded in 1936 by California Institute of Technology (Caltech) researchers, the laboratory is now owned and sponsored by NASA and administered and managed by Caltech. The primary function of the laboratory is the construction and operation of planetary robotic spacecraft, though it also conducts Earth-orbit and astronomy missions. It is also responsible for operating the NASA Deep Space Network (DSN). Among the major active projects at the laboratory, some are the Mars 2020 mission, which includes the ''Perseverance (rover), Perseverance'' rover; the Mars Science Laboratory mission, including the ''Curiosity (rover), Curiosity'' rover; the ''Mars Reconnaissance Orbiter''; the ''Juno (spacecraft), Juno'' spacecraft orbiting Jupiter; the ''Soil Moisture Active P ...

Snakebot
A snakebot, also referred to as a snake robot, is a biomorphic robot that resembles a snake. Snakebots have uses similar to those of certain types of soft robots. Snakebots can vary significantly in size and design. Their small cross-section-to-length ratios allow them to maneuver through tight spaces. Their ability to change shape allows them to traverse varied terrain. Snake robots are often designed by connecting multiple independent segments, which provides redundancy and enables continued operation even if some parts are damaged. Snakebots have been posited for a range of practical applications. A snakebot differs from a snake-arm robot in that, snakebots are usually self-contained, whereas snake-arm robots typically have mechanics remote from the arm itself, possibly connected to a larger system. Applications By mimicking the locomotion of snakes, snakebots can be used for tasks in multiple industries that traditional robots or human workers may find challenging or imp ...

Enceladus
Enceladus is the sixth-largest moon of Saturn and the 18th-largest in the Solar System. It is about in diameter, about a tenth of that of Saturn's largest moon, Titan. It is covered by clean, freshly deposited snow hundreds of meters thick, making it one of the most reflective bodies of the Solar System. Consequently, its surface temperature at noon reaches only , far colder than a light-absorbing body would be. Despite its small size, Enceladus has a wide variety of surface features, ranging from old, heavily cratered regions to young, tectonically deformed terrain. Enceladus was discovered on August 28, 1789, by William Herschel, but little was known about it until the two Voyager spacecraft, '' Voyager 1'' and '' Voyager 2'', flew by Saturn in 1980 and 1981. In 2005, the spacecraft '' Cassini'' started multiple close flybys of Enceladus, revealing its surface and environment in greater detail. In particular, ''Cassini'' discovered water-rich plumes venting fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunar Lava Tube
file:Mare Tranquillitatis pit crater.jpg, The Mare Tranquillitatis pit has been associated with a lava tube. Lunar lava tubes are lava tubes on the Moon formed during the eruption of Basalt, basaltic lava flows. When the surface of a lava flow cools, it hardens and the lava can channel beneath the surface in a tube-shaped passage. Once the flow of lava diminishes, the tube may drain, forming a hollow void. Lunar lava tubes are formed on sloped surfaces that range in angle from 0.4° to 6.5°. These tubes may be as wide as before they become unstable against lunar gravity, gravitational collapse. However, stable tubes may still be disrupted by seismic events or meteoroid bombardment. The existence of a lava tube is sometimes revealed by the presence of a "skylight", a place in which the roof of the tube has collapsed, leaving a circular hole that can be observed by lunar orbiters. Observational evidence An area displaying a lava tube and rilles is the Marius Hills region (). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lidar
Lidar (, also LIDAR, an acronym of "light detection and ranging" or "laser imaging, detection, and ranging") is a method for determining ranging, ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver. Lidar may operate in a fixed direction (e.g., vertical) or it may scan multiple directions, in a special combination of 3-D scanning and laser scanning. Lidar has terrestrial, airborne, and mobile applications. It is commonly used to make high-resolution maps, with applications in surveying, geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swathe mapping (ALSM), and Mars Orbiter Laser Altimeter, laser altimetry. It is used to make digital 3D modeling, 3-D representations of areas on the Earth's surface and ocean bottom of the intertidal and near coastal zone by varying the wavelength of light. It has also been in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robotic Sensing
Robotic sensing is a subarea of robotics science intended to provide sensing capabilities to robots. Robotic sensing provides robots with the ability to sense their environments and is typically used as feedback to enable robots to adjust their behavior based on sensed input.
