Enceladus

Enceladus is one of the major inner moons of Saturn along with Dione, Tethys, and Mimas. It orbits Saturn at a distance of 148,000 miles (238,000 km), falling between the orbits of Mimas and Tethys. It is tidally locked with Saturn, keeping the same face toward the planet. It completes one orbit every 32.9 hours within the densest part of Saturn’s E Ring, the outermost of its major rings, and is its main source.

Enceladus is, like many moons in the extensive systems of the giant planets, trapped in an orbital resonance. Its resonance with Dione excites its orbital eccentricity, which is damped by tidal forces, tidally heating its interior, and possibly driving the geological activity.

Enceladus is Saturn’s sixth largest moon, only 157 miles (252 km) in mean radius, but it’s one of the most scientifically compelling bodies in our solar system. Hydrothermal vents spew water vapor and ice particles from an underground ocean beneath the icy crust of Enceladus. This plume of material includes organic compounds, volatile gases, carbon dioxide, carbon monoxide, salts and silica.

With its global ocean, unique chemistry and internal heat, Enceladus has become a promising lead in our search for worlds where life could exist.

In 2005, Cassini’s multiple instruments discovered that this icy outpost is gushing water vapor geysers out to a distance of three times the radius of Enceladus. The icy water particles are roughly one ten-thousandth of an inch, or about the width of a human hair. The particles and gas escape the surface at jet speed at approximately 800 miles per hour (400 meters per second). The eruptions appear to be continuous, refreshing the surface and generating an enormous halo of fine ice dust around Enceladus, which supplies material to one of Saturn’s rings, the E-ring.

Several gases, including water vapor, carbon dioxide, methane, perhaps a little ammonia and either carbon monoxide or nitrogen gas make up the gaseous envelope of the plume.

Parting Shots of the Insight A and Insight B Systems, Alien Skies.

Now that all of the worlds of the Insight A and Insight B systems have been revealed, here are some parting shots before I begin my exploration of new star systems.

Insight A System - Inner-Most Planet (Insight A-I)

The Inner-most planet is a baked world orbiting perilously close to its sun at a distance of just 0.04 AU. The planet has a mass of roughly 0.56 Earth Masses and a diameter 93% that of Earth. It is rocky desert world. A thick carbon dioxide and sulfur dioxide atmosphere covers the surface with an atmospheric pressure 10 times that of Earth.

Surface temperatures are extreme, reaching 1,800 F during the day.  At these temperatures some surface rocks melt into lakes of magma and the surface glows a dull red at night. The atmosphere also contains clouds composed of liquid glass droplets. Despite it’s close orbital proximity to the sun, it is not tidally locked. The planet has a moderately elliptical orbit with an eccentricity of 0.10. This results in a 3 to 2 orbit to spin resonance. In other words the planet completes three rotations for every 2 orbits, just like the planet Mercury.

BTW Everyone, it looks like Space Engine version 0.999 is probably going to be released sometime soon, probably before the end of the year. Can’t wait to start taking pics in it.

Picture of the Day 2 - October 16, 2018

Here I come across the most Earth-like planet to date. The planet is covered in green vegetation, blue oceans and ice caps at the poles. This planet is located near the galactic core; therefore, the sky is full of bright stars, even more so than globular clusters.

TOUCHDOWN OF INSIGHT ON MARS! Man, this just never gets old. I am SO over the Moon (or Mars) each and every time our incredible civilization accomplishes such amazing technological feats. Congratulations to all who made this happen. Pop the corks!

One of the landing team members just mentioned that InSight will soon deploy instruments with which to search for water on Mars. Where there is water, there is life. It is highly unlikely that the water is sterile. I also would like to remind ourselves that life exists here in Earth where in the most inhospitable life conditions, extreme heat, extreme darkness, life exist. (At the exact time of reentry and touchdown, the street in front of my place was being blacktopped with 2 gigantic steel rollers causing the ground, foundation walls, windows to shake and vibrate. @krixomatic says, “Feels like we’re inside the lander!” I exploded with laughter. Can’t make this up.) What do you think guys?
