Voyager 2: Rings of Neptune (August 1989)

[whirligig-girl]

A modern Mellanoid Slime Worm spacecraft, the Ice Giants Explorer. Intended to launch in 2383, it ended up fast-tracked and launched under a completely different mission. It would have explored the four ice giants of the Zwo-Nmu system: Glarpi, Shpler, Euaua, and Flible, with a possible mission extension to distant, never-before-seen planet Schmidt. It's depicted here using its T.E.N.D.R.I.L. (Teleoperated extendible-node robotic interface limb) to deploy one of its many robotic probes to land on a small captured satellite of Shpler, S/2351 S2.

The spacecraft has two main propulsion systems, a fission-impulse drive and a pulsed warp engine. The fission-impulse drive are modified solid-core nuclear-thermal-rockets utilizing subspace field coils on the exhaust end similar to those utilized on starfleet impulse drives. However, the power generation for those impulse coils is provided by a fission reactor, instead of a fusion reactor. This results in approximately a doubling of the specific impulse of the engine while preserving thrust characteristics.

The pulsed warp engine uses a bank of high-density capacitors charged using the fission reactors, to provide short bursts of warp speed. Modern mellanoid transwarp coils can provide speeds of up to warp 5 on the new scale, but are bottlenecked by the power generation and storage rate. As such the pulsed warp drive technology is currently not usable for interstellar exploration, but it does allow for much faster intra-system manuevers. (The bright photon-wakes visible from many astronomical units away, and their associated radiation hazards, are considered an acceptable risk.)

Neptune & Triton. Neptune's with its Rings and 14 of its known Moons. Taken by the James Webb Space Telescope. Triton has a surface of frozen condensed nitrogen, which reflects 70% of the sunlight that hits it, making it brighter than Neptune.

Praetor Rykard, reveals...

Blarghh! Animation practice, I dunno what to put in there so, have fun?

This would be cool for a spacemass day, many people still don't realize Uranus has rings

Gonna share some submissions for #spacemas!!

This is such a cool picture of Uranus- and they’re right! People do often forget that all of the gas giants have rings- even Jupiter!

It's late I'm tired have some

Unwarranted Opinions on The Solar System

The Sun: solidly middle-of-the-road star. Only really impressive in conjunction with The Moon (see below), but if it ain't broke, don't fix it. 5/10.

Mercury: A pretty uninspired start to the planets, all things considered. Venus does the whole "being hot and close to the sun" thing way better, so I don't really see the point. 0/10.

Venus: Hot, bright, instantly recognizable, and a fascinating counterpoint to Earth. 9/10 only because it doesn't have a nice big moon named Cupid or something - I feel like there was a missed opportunity there.

Earth: This might just be four billion years of evolution talking, but this planet is literally perfect. Dry land and oceans constantly changing shape and thus never getting stale; an atmosphere that filters out most dangerous radiation without being too hard to see through; a functioning magnetosphere; the list of its virtues goes on and on. And even if that somehow weren't enough, I've literally never seen another planet with life on it and that's enough to get Earth an automatic 10/10 for originality.

The Moon: THE best satellite in the entire Solar System and if you disagree we WILL fight. It's a beautiful color, its endless tiny details variably highlighted by its phases mean there's always something new to look at, and it's just the right size and distance from Earth to fully eclipse the Sun and leave only its corona and prominences exposed in the most spectacular display in space or anywhere. If you need me to explain why that makes it THE BEST I will be forced to assume you have no brain. Infinity/10, I am in love.

Mars: Basic details out of the way - I love the color and the extreme geography. Having the biggest mountain in the Solar System counts for something. Besides that, it's thematically fascinating, haunted by the ghosts of what would have been had it been able to hold on to its magnetosphere and atmosphere. I'd give it a perfect score but its dust storms have been unkind to the rovers and I neither forget nor forgive. 8/10.

Phobos & Deimos: stupid useless space potatoes. 1/10 only because Mars will have rings when Phobos finally bites it.

The Asteroid Belt: Meh. 0/10.

Ceres: It may be the only dwarf planet inside the orbit of Neptune, but it's still a dwarf planet. 2/10.

Trojans: Asteroid Belt but "artistic." 1/10.

Jupiter: impressive size, tasteful color palette, and the red spot gives it a bit of intrigue. Too many moons though. 7/10.

The Galilean Moons: fascinating orbital resonance. Shame Callisto won't get with the program. 7/10.

All of Jupiter's Other Moons: too many, and they keep finding new ones, none of which are spherical. Quantity isn't everything, guys. 3/10.

Saturn: the boring color palette is more than made up for, and the excessive number of moons justified, by those SPECTACULAR rings. No other planet has rings that beautiful. Why aren't more planets like this? 10/10.

Saturn's Moons: yeah, some of them have fun little gimmicks, but I really only like them inasmuch as they keep the rings in place. 5/10.

Uranus: the massive axial tilt is refreshingly original and the blue color is easy on the eyes. The lack of rings or memorable moons is a bit of a letdown. A lesser reviewer might make base puns but all the astronomers I know pronounce it differently and the jokes no longer land. 8/10.

Neptune: redundant. 2/10.

The Kuiper Belt: mysterious and full of comets. The Asteroid Belt could never. 6/10.

Pluto: I don't have anything against Pluto itself - the fact that it's so tiny and yet has (at least) five moons gives it a certain charm that a body like Mercury simply lacks. It's the fandom I can't stand. There are three criteria for a body to be classified as a planet, Pluto does not meet one of them, and the sentimental value you place on it and its mistaken former classification does not override this. Any appeal to the perceived injustice of Pluto's classification reveals a deep-seated hypocrisy - I don't see any of you going to bat for Eris. All that said, I will not let this nuisance compromise Pluto's rating. 9/10 for being a funny little guy.

Eris: fun fact, Eris is smaller in diameter but more massive than Pluto. Other than that, I'm not sure what it's got going for it. To be fair to Eris though, neither does anybody else. 5/10.

Haumea: It's an egg with two moons and a ring system. What more could you want? 8/10.

Other Dwarf Planets: Eh. 3/10 for mystery.

The Oort Cloud: the most distant extremity of our Solar System, full of comets and possibility. 10/10.
