The density of Tethys is 0.97 g/cm³, indicating that it is composed almost entirely of water-ice. Its surface is one of the most reflective (at visual wavelengths) in the solar system, with a visual albedo of 1.229.
As someone who is rapidly closing in on 50 years of age, I’m of that generation that used to play “Star Trek” on the jungle gym back in elementary school. I’ve watched all the TV series, seen all the movies … and yet, watching this new film in the theater just yesterday, I suddenly started feeling very OLD. There is no doubt that J.J. Abrams wanted to revive the “Star Trek” franchise, and at the same time make it appeal to a younger, hipper audience. I’m not going to get all apoplectic over the film’s straying from “canon” … AFTER ALL, this is science fiction, not World History. And anyway, I can attribute those changes to the “alternate realities” that the new film employs as easily as it employs Red Matter (retrieved, I guess, the the Universe’s biggest Lava Lamp). Of course, no amount of “alternate reality” could change James T. Kirk’s predilection for green-skinned alien babes.
But there’s one thing I cannot forgive J.J. Abrams for, and that’s depicting Titan so far above Saturn’s ecliptic! Sure, it was a lovely, DRAMATIC shot, but can’t scientific accuracy figure into the film JUST A LITTLE BIT??? I'm SURE the folks here at CICLOPS had to be squirming just a tad. As we all know, a realistic shot would've placed Saturn much farther in the distance, with the rings nearly edge-on. But let's face it: When it comes to movies, eye candy will win out over scientific accuracy every time.
I will also say this: The death of Spock’s mother, Amanda Grayson, upset me deeply. You can say what you want about “alternate realities,” but I really don’t think this was necessary to the plot of the film. Even though she appeared in just one episode of the original series and a couple of the earlier movies, I was very fond of her, especially as portrayed with such grace by Jane Wyatt.
All that having been said, I’ll give the film 7 out of 10 stars. Here’s hoping the NEXT film in the franchise is just a little MEATIER.
