"The spacecraft would also use a number of mechanical components to acquire the samples for analysis. It has already explored La Pilita, a 115 meter sink. Well, Shakespeare it ain't. The reduced density at greater distances is likely due to temperature: denser, rocky and metal material condenses out first, close to Jupiter or the Sun, while lighter-weight icy material only condenses out at larger distances where it is colder.Distance from Jupiter also determines how much tidal heating the Galilean satellites experience — Io, closest to Jupiter, is heated so much that it is the most volcanically active body in the solar system, and it likely long ago drove off any water it had when it formed. Even if Europa isn’t ejecting free samples into space, a 2018 study concluded that samples of Europa’s ocean could get frozen into the base of the moon’s ice shell, where the ice makes contact with the ocean. The first is to analyze the surface composition, and the second is to characterize both the surface and subsurface conditions to determine the viability of Because Europa has no atmosphere, a heat shield would not be required for the lander, but that also means a parachute would do no good in slowing the craft for a soft landing. The Next Full Moon is the Strawberry Moon, Mead Moon, Honey Moon, Vat Purnima, Poson Poya, and the LRO Moon. A robotic arm, sample excavation tool, sample collection device, and sample transfer mechanisms deposit the material to the primary science instruments, which are housed within the spacecraft for radiation shielding. A Europa may hold the clues to one of NASA's long standing goals – to determine whether or not we are alone in the universe. DEPTHX was the first robotic system of any kind to implement three-dimensional simultaneous localization and mapping (SLAM).

The USA Science & Engineering Festival is looking for a Mascot and we need YOUR help to design the new face of the largest celebration of science and engineering! As the ice shell distorts and flexes from tidal forces, warmer and less-dense ice would rise, carrying the ocean samples to the surface where a spacecraft could analyze it remotely, using infrared and ultraviolet instruments, among others. Decades ago, science fiction offered a hypothetical scenario: What if alien life were thriving in an ocean beneath the icy surface of Jupiter’s moon Europa? Dr. Lori Glaze DEPTHX was the first robotic system of any kind to implement three-dimensional simultaneous localization and mapping (SLAM). Will a separate vehicle be necessary to punch a hole in the crust for safe entry? National Aeronautics and Space Administration (NASA) has found out a unique way to test the DEPTHX robot, which is being developed to find life on Jupiter’s icy moon, Europa. There also will be a partial penumbral eclipse of the Moon. Isaac Asimov (1920 - 1992)...once they are discovered; the point is to discover them. John Spear, for one, wouldn’t mind if life on Europa turned out to be entirely microscopic.
Find out what else to watch for in the skies during the next few weeks. Those four moons are likely about the same age as the rest of the solar system — about 4.5 billion years old.In fact, the Galilean satellites are sometimes called a “mini solar system” since they formed from the leftovers of Jupiter similar to how Earth and other planets formed from gas and dust left over from the formation of our Sun.
Director, NASA Planetary Science Division: Jupiter’s equator (and the orbital plane of its moons) are tilted with respect to Jupiter’s orbital path around the Sun by only 3 degrees (Earth is tilted 23.5 degrees).
Based on Europa's icy composition, scientists think the most likely material to create this magnetic signature is a global ocean of salty water. It was also the first such system to make its own decisions on where and how to collect samples. DEPTHX has 54 sonar sensors spaced around its frame and controlled by two sonar arrays. Fun — and even educational — NASA activities to do at home.
Europa has a layer of ice and water on top of a rocky and metal interior, while Ganymede and Callisto actually have higher proportions of water ice and so lower densities. Recently discovered object 2019 LD2, originally believed to be the first cometary “Jupiter Trojan” asteroid, turned out to be an interloper comet masquerading as a member of the Trojan population. This week, DEPTHX explores the 1,000ft deep Zacaton Lake in Mexico, the world's deepest sinkhole. Flexing from the tides likely creates the moon’s surface fractures. So if we replaced our Moon with Europa, it would appear roughly the same size in the sky as our Moon does, but brighter — much, much brighter. So be weary not to let your house…This week, in the Mexican oil city of Tampico, an orb-like, robotic submarine begins its 1,000-foot plunge to the bottom of an underwater cavern, the largest sinkhole in the world.

I do, but sadly for the newspaper business I read them online. The sonar uses pulses of high-energy sound waves and their reflections to locate objects within a 250- to 300-meter radius of the vehicle.
Intriguing Europa.
The picture is of DEPTHX. It can swim through a water-filled cavern creating its own map.
