Outward Bound: Colonizing Jupiter

Jupiter and its moon are a rarely considered prospect for colonization, but potentially the ripest opportunity for it in the solar system. In this episode of the Outward Bound series we will examine the options for colonizing each of Jupiter's primary moons and even discuss ways to colonize the giant planet itself.

If you’d like to dig into the analysis of radiation data, the paper is Kollman et al., “A heavy ion and proton radiation belt inside of Jupiter’s rings,” Geophys. Res. Lett 44, 5259-5268 (abstract).

Jupiter rotates!

New Horizons' long-range camera LORRI monitored Jupiter's rotation as the spacecraft approached on January 9 and 10, 2007.
The 11 images in this animation were each taken an hour apart and cover one full rotation of the planet.
During the animation, first Ganymede and then Io cross the field of view, casting their shadows onto the planet.
There are a total of six of these movies planned for New Horizons' approach to Jupiter; the last of those should have been taken on Sunday,
so stay tuned to the New Horizons site for those. There are only three other sets of images planned for the next month: a handful of "Kodak moments,"
images taken primarily for their prettiness.

A Journey to Jupiter

Published on Feb 8, 2017 This animation of Jupiter is made from more than 1,000 images taken by 91 amateurs from around the world between the 19th of December 2014 and the 31st of March 2015. After collecting the images, they have been remaped into cylindrical projections by Christoffer Svenske and Johan Warell. I have then color corrected, stacked and seamlessly stitched them into a total of 54 complete maps. To slow down the rapid motion, I have interpolated an image in between each pair of maps for a total of 107. The polar projections are a little special as I have made them stretch from pole to pole, not just from pole (center) to equator (outside) as traditionally represented. The reason is that I find it more interesting to be able to follow the movements of all the cloudbelts regardless of the projection. It has taken more than a year to complete this video that shows the motion of Jupiter's cloud belts and the rotation of the Great Red Spot in high resolution, all accelerated one million times! It also shows the technical skills of the world wide community of amateur planetary photographers to be able to reach this high level of details that can be tracked across the planet during 250 revolutions. Thanks to all of you for contributing to this project.

The Voyager 3 project from Sweden

Voyager 3 from Peter Rosén on Vimeo.

In 1979, the Voyager 1 probe took a stunning series of images on its final approach to Jupiter that clearly showed the intricate movement of the cloudbelts for the first time. 35 years later, almost to the day, a group of 7 swedish amateur astronomers set out to replicate this odyssey and the historical NASA-footage but with images taken with their own ground-based telescopes. Welcome to the Voyager 3 Project.

Jupiter’s Magnetosphere Will Blow Your Mind While it Kills Your Spacecraft

Image: This graphic shows a new radiation zone surrounding Jupiter, located just above the atmosphere near the equator, that has been discovered by NASA’s Juno mission. The new radiation zone is depicted here as a glowing blue area around the planet’s middle. Meanwhile, Juno’s microwave radiometer (MWR) instrument also culled data during Juno’s passage over the Great Red Spot in July of 2017. The figure below represents six channels of these data. Using the MWR, Juno can see deeper than any previous ground- or space-based observations into the clouds. It’s interesting to note that the large-scale structure of the Great Red Spot is evident as deep into the planet as the MWR can observe. 16,000 kilometers wide, the Great Red Spot is a vast crimson storm that has been monitored since 1830. It was twice Earth’s diameter when the Voyagers studied it but has since diminished in width.

The bright stars and the asteroid (circled in yellow) appear black and the sky white in this negative image. Credit: C. Veillet / Large Binocular Telescope Observatory. Namouni and Morais used computer simulations to track the errant asteroid back in time, arguing that 2015 BZ509 has moved this way since the birth of the Solar System some 4.5 billion years ago, an indication that it could not have formed there originally. The case also relies on the fact that the Sun formed in a tightly packed star cluster where movement of objects ejected by gravitational forces within their own system into orbits around other stars would not have been uncommon. Thus this rogue asteroid may well contain information about planet formation and evolution as well as telling us more about the Sun’s original siblings. So what exactly do we know about this object? 2015 BZ509 is in a resonant, co-orbital motion with Jupiter and represents the first discovery of a retrograde co-orbital asteroid with Jupiter or any other planet. Its orbital eccentricity of 0.3805 takes it inside and then outside of Jupiter’s orbit at its closest approaches (176 million kilometers). The orbital period is 11.65 years and the inclination is 163 degrees, an evidently stable orbit if a complicated one.

Jupiter's Moon IO

Life on IO?????

More Frank R. Paul art this time showing the inhabitants of one of Jupiter's moons. This time it's weird penguin/chicken people.

Linda Morabito spotted the puzzling plume off Io’s limb in this photo, taken on March 8, 1979, three days after Voyager 1’s encounter with Jupiter. It really does look like another moon poking out from behind Io. A second plume over the terminator (border between day and night) catches the rays of the rising Sun. Credit: NASA / JPL

This five-frame sequence (Repeating Sequence on this video) of New Horizons images captures the giant plume from Io's Tvashtar volcano. Snapped by the probe's Long Range Reconnaissance Imager (LORRI) as the spacecraft flew past Jupiter earlier this year, this first-ever "movie" of an Io plume clearly shows motion in the cloud of volcanic debris, which extends 330 kilometers (200 miles) above the moon's surface. Only the upper part of the plume is visible from this vantage point -- the plume's source is 130 kilometers (80 miles) below the edge of Io's disk, on the far side of the moon. The appearance and motion of the plume is remarkably similar to an ornamental fountain on Earth, replicated on a gigantic scale. The knots and filaments that allow us to track the plume's motion are still mysterious, but this movie is likely to help scientists understand their origin, as well as provide unique information on the plume dynamics. Io's hyperactive nature is emphasized by the fact that two other volcanic plumes are also visible off the edge of Io's disk: Masubi at the 7 o'clock position, and a very faint plume, possibly from the volcano Zal, at the 10 o'clock position. Jupiter illuminates the night side of Io, and the most prominent feature visible on the disk is the dark horseshoe shape of the volcano Loki, likely an enormous lava lake. Boosaule Mons, which at 18 kilometers (11 miles) is the highest mountain on Io and one of the highest mountains in the solar system, pokes above the edge of the disk on the right side. The five images were obtained over an 8-minute span, with two minutes between frames, from 23.50 to 23.58 Universal Time on March 1, 2007. Io was 3.8 million kilometers (2.4 million miles) from New Horizons; the image is centered at Io coordinates 0 degrees north, 342 degrees west. The pictures were part of a sequence designed to look at Jupiter's rings, but planners included Io in the sequence because the moon was passing behind Jupiter's rings at the time.

Jupiter?s moon Io features at least 400 active volcanoes, making it the most volcanically active world in our Solar System.
However, the location of the volcanoes on Io just doesn?t match up with scientific models that predict how the moon?s interior is heated.
?Rigorous statistical analysis of the distribution of volcanoes in the new global geologic map of Io,?
said Christopher Hamilton of the University of Maryland, College Park and the Goddard Spaceflight Center.
?We found a systematic eastward offset between observed and predicted volcano locations that can?t be reconciled
with any existing solid body tidal heating models.?

The Electrical "Volcanoes" of Jupiter's Moon Io | Space News

Published on Apr 25, 2013 The so-called "volcanoes" on Jupiter's moon Io have long been conventionally interpreted as the effect of tidal forces acting on the moon.
But a recent scientific paper has announced that this longstanding explanation does not fit with the actual location of the plumes.
Is it possible that this failure of theory could cause planetary scientists to reconsider the electrical explanation first offered by
astrophysicist Thomas Gold and later by plasma scientists Anthony Peratt and Alex Dessler?

The Interior of IO

Of Jupiter?s four large Galilean satellites, Io is the closest to the planet.
It?s about the same size as Europa and the Earth?s Moon. It may be the strangest satellite humans have ever studied.
Voyager photos of Io revealed erupting volcanoes. This wasn?t too surprising, because Jupiter?s intense tidal forces heat
the interior of the satellite, just like on Europa. But subsequent observations show that volcanoes are always erupting
on Io - in fact, it?s the most volcanically active world in the solar system! Material shot up by the many volcanoes
rises high above the surface of the little satellite and then falls back in a lazy arc due to Io?s weak gravity.
Volcanic activity adds about 10 centimeters of new material to the surface each year.

On Christmas Eve, as millions upon millions of people focused on wrapping gifts and getting ready for the holidays,
an amateur astronomer gave a small gift to the world. The person turned a telescope and camera to Jupiter and caught volcanic
Io going across the face of the gas giant. This happened just a few days after professional astronomers caught a rare eclipse
involving that very same moon.

Jupiter's Moon: Io Rotation - HD Kurdistan Planetarium Kurdistan Planetarium

Published on Apr 26, 2012 Io is the innermost of the four Galilean moons of Jupiter and, with a diameter of 3,642 kilometers, the fourth-largest moon in the Solar System.
It was named after Io, a priestess of Hera who became one of the lovers of Zeus. Nevertheless, it was simply referred to as Jupiter I, or
The first satellite of Jupiter, until mid-20th century. With over 400 active volcanoes, Io is the most geologically active object in the Solar System. Its surface is dotted with more than 100 mountains,
some which are taller than Earth's Mount Everest. Unlike most satellites in the outer Solar System (which have a thick coating of ice),
Io is primarily composed of silicate rock surrounding a molten iron or iron sulfide core. Although not proven, recent data from the Galileo orbiter indicates that Io might have its own magnetic field Io has an extremely
thin atmosphere made up mostly of sulfur dioxide (SO2). If a surface data or collection vessel were to land on Io in the future,
it would have to be extremely tough (similar to the tank-like bodies of the Soviet Venera landers) to survive the radiation and magnetic fields

Thanks to a mission extension, NASA’s Juno probe continues to orbit Jupiter, being only the second spacecraft in history to do so. Since it arrived around the gas giant on July 5th, 2016, Juno has managed to gather a great deal of information on Jupiter’s atmosphere, magnetic and gravity environment, and its interior structure.

Io’s Largest Volcano, Loki, Erupts Every 500 Days. Any Day Now, It’ll Erupt Again.

Jupiter’s moon Io is in stark contrast to the other three Galilean moons. While Callisto, Ganymede, and Europa all appear to have subsurface oceans, Io is a volcanic world, covered with more than 400 active volcanoes. In fact, Io is the most volcanically active body in the Solar System.

Exploring The Icy Moons of Jupiter. NASA's Europa Clipper and ESA's JUICE

Mars is the place that most of our spacecraft, landers and rovers are studying, searching for any evidence that life ever existed somewhere else in the Solar System. But talk to planetary scientists, and they’re just as excited about the ocean worlds of the Solar System; the moons, asteroids, dwarf planets and Kuiper Belt objects where there could be vast oceans of liquid water under thick shells of ice. The perfect environment for life to thrive. We’ve only had tantalizing hints that these oceans are there, but NASA is building a spacecraft that will study one of these worlds in detail: the Europa Clipper. And they’re not the only ones. The European Space Agency is building their own mission, the Jupiter Icy Moons Explorer. Our Book is out!

Many people think that the answer to ‘what is the largest moon in the Solar System’ is our Moon.
It is not. Our Moon is the fifth largest natural satellite. Ganymede, a moon of Jupiter, is the largest in this solar system.

Jupiter's Moon Callisto


Colonizing Callisto - Third Largest Moon In The Solar System

Callisto is a pretty big moon that has some conditions which are very friendly for a human colony. Because of that in this video, I take a look at how we could go about establishing a big colony on this moon of Jupiter and how we could even turn its surface conditions to be even better for humans in the really far future.

Jupiter's Moon: Callisto Rotation

Uploaded on Jan 6, 2010 Callisto (pronounced /kəˈlɪstoʊ/,or as Greek Καλλιστώ) is a moon of the planet Jupiter, discovered in 1610 by Galileo Galilei. It is the third-largest moon in the Solar System and the second largest in the Jovian system, after Ganymede. Callisto has about 99% the diameter of the planet Mercury but only about a third of its mass. It is the fourth Galilean moon of Jupiter by distance, with an orbital radius of about 1 880 000 km. It does not form part of the orbital resonance that affects three inner Galilean satellites—Io, Europa and Ganymede— and thus does not experience appreciable tidal heating. Callisto rotates synchronously with its orbital period, so the same face is always turned toward Jupiter. Callisto's surface is less affected by Jupiter's magnetosphere than the other inner satellites because it orbits farther away. Callisto is composed of approximately equal amounts of rock and ices, with a mean density of about 1.83 g/cm3. Compounds detected spectrally on the surface include water ice, carbon dioxide, silicates, and organic compounds. Investigation by the Galileo spacecraft revealed that Callisto may have a small silicate core and possibly a subsurface ocean of liquid water at depths greater than 100 km. The surface of Callisto is heavily cratered and extremely old. It does not show any signatures of subsurface processes such as plate tectonics, earthquakes or volcanoes, and is thought to have evolved predominantly under the influence of impacts. Prominent surface features include multi-ring structures, variously shaped impact craters, and chains of craters (catenae) and associated scarps, ridges and deposits. At a small scale, the surface is varied and consists of small, bright frost deposits at the tops of elevations, surrounded by a low-lying, smooth blanket of dark material. This is thought to result from the sublimation-driven degradation of small landforms, which is supported by the general deficit of small impact craters and the presence of numerous small knobs, considered to be their remnants.The absolute ages of the landforms are not known. Callisto is surrounded by an extremely thin atmosphere composed of carbon dioxide[6] and probably molecular oxygen, as well as by a rather intense ionosphere. Callisto is thought to have formed by slow accretion from the disk of the gas and dust that surrounded Jupiter after its formation. Its slowness and the lack of tidal heating prevented rapid differentiation. The slow convection in the interior of Callisto, which commenced soon after formation, led to partial differentiation and possibly to the formation of a subsurface ocean at a depth of 100150 km and a small, rocky core. The likely presence of an ocean within Callisto indicates that it can or could harbor life. However, this is less likely than on nearby Europa. Various space probes from Pioneers 10 and 11 to Galileo and Cassini have studied the moon. Callisto has long been considered the most suitable place for a human base for future exploration of the system of Jupiter. Discovered by G. Galilei S.
