Oct 13, 2014: NASA’s Lunar Reconnaissance Orbiter (LRO) has provided researchers strong evidence the moon’s volcanic activity slowed gradually instead of stopping abruptly a billion years ago.

This results in the surface receiving some 8 rem of radiation per day – which is 333 times the average of what Earth-bound organisms experience in a year. For one, as Jupiter's largest moon, Ganymede has a gravitational force of 1.428 m/s2 (the equivalent of 0.146 g) which is comparable to Earth's Moon.

The plasma co-rotating with Jupiter impinges on the trailing side of the Ganymedian magnetosphere much like the solar wind impinges on the Earth's magnetosphere. The dipole magnetic field created by this permanent moment has a strength of 719 ± 2 Teslas (nT) at Ganymede's equator, and roughly twice that at the poles (1440 nT). Unfortunately, beyond this, Ganymede presents numerous challenges for colonization. autonoe belonging to the Nymphalidae was determined. It would also be insufficient to retain much heat. In Greek mythology, Autonoë (/ ɔː ˈ t ɒ n oʊ. The Ganymedian magnetosphere has a region of closed field lines located below 30° latitude, where charged particles (electrons and ions) are trapped, creating a kind of radiation belt. The interaction between the Ganymedian magnetosphere and Jovian plasma is in many respects similar to that of the solar wind and Earth's magnetosphere. The chemical composition of Autonoë madeirensis bulbs was characterized as part of a systematic phytochemical study of this species. Sinope, in particular, is suspected of starting out as an independent asteroid. This document is subject to copyright. The compounds reported were … None of the Pasiphae members is massive enough to pull itself into a sphere, so they are probably all irregularly shaped. This magnetic moment also carves a part of space around Ganymede, creating a tiny magnetosphere embedded inside that of Jupiter with a diameter of about 10,525 – 13,156 km.

Their semi-major axes (distances from Jupiter) range between 19.3 and 22.7 Gm, their orbital inclinations between 145.7° and 154.8°, and their orbital eccentricities between 0.02 and 0.28. The results may contribute to the chemotaxonomy of Autonoë genus and lead to a rapid tool for the systematic characterization of these compounds in plant extracts.Fundação para a Ciência e Tecnologia (FCT/POCTI/FEDER. With tidal heating increasing during such resonances, the mantle may have insulated the core, preventing it from cooling.

The chemical composition of Autonoë madeirensis bulbs was characterized as part of a systematic phytochemical study of this species. Hipparchia autonoe (Esper, 1783) is a protected butterfly species found in Mt.

It … The main ion species in the magnetosphere is single ionized oxygen, which fits well with Ganymede's tenuous oxygen atmosphere. Guiding that effort are NASA test directors, or NTDs.

While en route to Pluto, the probe obtained topographic and composition mapping data of Europa and Ganymede during its flyby of Jupiter. and Terms of Use.

Autonoë, one of the Nereids, sea nymph daughters of Nereus and Doris.

The Next Full Moon is the Strawberry Moon, Mead Moon, Honey Moon, Vat Purnima, Poson Poya, and the LRO Moon. Scores of distinctive rock deposits observed by LRO are estimated to be less than 100 million years old.

Composition and Surface Structure: With an average density of 1.936 g/cm 3, Ganymede is most likely composed of equal parts rocky material and water ice. A possible solution to this, similar to what has been proposed for Europa, would be for colonists to build settlements within the icy mantle, or possibly under the surface of the ice entirely.

In Greek mythology, Autonoë (/ɔːˈtɒnoʊ.i/; Ancient Greek: Αὐτονόη means "think for oneself") may refer to the following personages: Online version at the Perseus Digital Library. These missions returned more specific information on its physical characteristics and resolved features to 400 km (250 mi) on its surface. All of these make Ganymede an intriguing prospect for future exploration.

For example, changes of as much as 1 Gm in semi-major axis in 2 years, 0.5 in eccentricity in 12 years, and as much as 5° in 24 years have been reported. Autonoe was discovered Dec. 10, 2001 by Scott S. Sheppard, David C. Jewitt, and Jan T. Kleyna at the Mauna Kea Observatory in Hawaii. The rocket booster segments that will help power NASA’s first Artemis flight test mission around the Moon arrived at KSC. There also will be a partial penumbral eclipse of the Moon.

06 89 34 67 49 The ESA's contribution was renamed the Jupiter Icy Moon Explorer (JUICE) in 2012, and obtained a launch slot aboard the ESA's Cosmic Vision science program (scheduled for launch in 2022 or 2024).

Autonoe is a Moon that orbits round the planet Jupiter. Get weekly and/or daily updates delivered to your inbox.

Mean orbital elements are the averages calculated by the numerical integration of current elements over a long period of time, used to determine the dynamical families. An analysis published in 2014, taking into account the realistic thermodynamics for water and effects of salt, suggests that Ganymede might have a stack of several ocean layers separated by different phases of ice, with the lowest liquid layer adjacent to the rocky mantle below.

This is due to differences in color (varying from red to gray), and differences in orbital eccentricity and inclination among the members of the Pasiphae group.

The prevalence of water ice means that colonists could also produce breathable oxygen, their own drinking water, and would be able to synthesize rocket fuel.

Hipparchia autonoe (Esper, 1783) is a protected butterfly species found in Mt. Autonoe is considered a member of the Pasiphae group, a family of Jovian satellites which have similar orbits and are therefore thought to have a common origin.

You can unsubscribe at any time and we'll never share your details to third parties. However, the mission was canceled in 2005 because of budget cuts.

This heat could be transferred into the water via hydrothermal vents, which could provide the necessary heat and energy to sustain life.

You can be assured our editors closely monitor every feedback sent and will take appropriate actions. Several probes flying by or orbiting Jupiter have explored Ganymede more closely, including four flybys in the 1970s, and multiple passes in the 1990s to 2000s. Didymos B is getting an official name of its own: Dimorphos.

NASA Official: The Ananke group is a group of retrograde irregular satellites of Jupiter that follow similar orbits to Ananke and are thought to have a common origin. Sufficient enough to limit the effects of muscle and bone degeneration, this lower gravity also means that the moon has a lower escape velocity – which means it would take considerably less fuel for rockets to take off from the surface.

All of the Pasiphae moons are retrograde, which means that they orbit Jupiter in the opposite direction from the planet's rotation.

Since this value is near the approximate diameter of Ananke itself, it is likely the parent body was not heavily disrupted.

The compounds reported were mainly identified on the basis of gas-chromatographic/electron ionization, electrospray ionization …

In 1995, the Galileo spacecraft orbited Jupiter and went on to make six close flybys between 1996 and 2000. The International Astronomical Union (IAU) reserves names ending in -e for all retrograde moons, including this group's members. This enhanced-color image from NASA’s Juno spacecraft captures the striking cloud bands of Jupiter’s southern latitudes.

Science Writer: The next full Moon will be early Sunday morning, July 5, 2020. Scientists are using modern image processing techniques to create new views of Europa's surface. However, the existence of Ganymede's magnetosphere remains a bit of a mystery.

A Ganymede orbiter based on the Juno probe was also proposed in 2010 for the Planetary Science Decadal Survey. Another explanation is a remnant magnetization of silicate rocks in the mantle, which is possible if the satellite had a more significant dynamo-generated field in the past.
