Saara loves travel, and is generous in sharing her vacations spots with her friends. Her friends have second thoughts, if they have any brains though...
Note the silvery side of one of Saara's Excursion Vehicles to the right of the picture. The planetscape and Tangel's tail are reflected in it. Also of interest are the two gas giants in mutual orbit. Elliptically distorted by their rotational velocities, they must be near the point of breaking up.
You may also notice that I decided to stay home. Go to the next picture to see why.

That would kill a human as ice crystals would form in the cells and rip them apart as flesh flash froze, oxygen would be a liquid on the ground since it liquefies at -297 degrees F and nitrogen would be just a few degrees from liquifing so air would be a non issue. Touching a human after being exposed to these temperatures even for just a few seconds could cause their frozen body to shatter like glass. I imagine Tangel is made from sterner stuff or Saara has some medical magic up her sleeve.
Yep, that's true. Although biology labs do store bacterial cells at below freezing (-80 C), they add 20% glycerol to inhibit crystal formation. In fact, flashing freezing/thawing cycles are used to lyse (i.e., break apart) cells, mostly with liquid nitrogen. As for the "shattering like glass", that's only possible for the more fragile, thin bits (hair, ears) and only with a decent amount of force. For all intents and purposes, the human body is a liquid protein shake; if you've ever taking a cup of frozen liquid out of the freezer, you know how sturdy that can be.
The freezer only goes down to around -10F, cast iron gets brittle at -100F, tap a bulldozer with a hammer at -200F and it breaks like glass, touching water ice at -300F turns it into a powder. I work as a cryogenic technician and I know these things from my learnings :P Trust me, you expose human flesh to -300F it's going to get frozen and brittle quickly, cryogenic technicians have lost countless fingers that way.
Now this is what I love. I dearly appreciate solid, logical refutations of comments I make, backed up by experiences/evidence of an expert, in this case Mr. Kathmandu.
I've worked with liquid nitrogen (-196C, -320F) and while thin objects do become brittle upon exposure, I've yet to see this "shattering" effect on objects of at least 3 in width. I agree that it becomes like glass, but I would think that a frozen arm acting like a 3 inch solid tube of glass would require a pretty good tap to break. Beyond minor sublimation (such as is often seen with frozen foods drying out) I've never seen water "powder" at touch at -300F. But, then, I'm a biochemist and Kathmandu, as a cryogenic technician, would probably have more experience than I.

I would imagine if there were a way to thaw Tangel' out safely, Saara would come up with it. Of course, it would be uncharacteristically stupid of her to let Tangel' freeze in the first place. But such is humour.
Tangel' doesn't have invisible wings but the ship has a kind of bird painted on the side, a personal touch to Saara's vehicles.

This reminds me of Larry Niven's story "Wait it Out", in which an astronaut stranded on Pluto tries to preserve himself cryogenically by stripping off his spacesuit on the planet's surface. The only snag is that through a quirk of physics he remains fully conscious while frozen.
