"Quite possible," replied Redgrave, "and, if you like, we'll go and prove it. Of course, if the Astronef weighs absolutely nothing between Saturn and the rings, we can easily get away. The only thing that I object to is getting into this 170,000-mile vortex, being whizzed round with Saturn every ten and a half hours, and sauntering round the Sun at 21,000 miles an hour."
"Don't!" she said. "Really it isn't good to think about these things, situated as we are. Fancy, in a single year of Saturn there are nearly 25,000 Earth-days. Why, we should each of us be about thirty years older when we got round, even if we lived, which, of course, we shouldn't. By the way, how long could we live for, if the worst came to the worst?"
"Given water, about one Earth-year at the outside;" "but, of course, we shall be home long before that."
"If we don't become one of the satellites of Saturn," she replied, "or get dragged away by something into the outer depths of Space."
Meanwhile the downward speed of the Astronef had been considerably checked. The vast circle of the rings seemed to suddenly expand, and soon it covered the whole floor of the Vault of Space.
As she dropped towards what might be called the limit of the northern tropic of Saturn, the spectacle presented by the rings became every minute more and more marvellous—purple and silver, black and gold, dotted with myriads of brilliant points of many-coloured light, they stretched upwards like vast rainbows into the Saturnian sky as the Astronef's position changed with regard to the horizon of the planet. The nearer they approached the surface, the nearer the gigantic arch of the many-coloured rings approached the zenith. Sun and stars sank down behind it, for now they were dropping through the fifteen-year-long twilight that reigns over that portion of the globe of Saturn which, during half of his year of thirty terrestrial years, is turned away from the Sun.
The further they fell towards the rings the more certain it became that the theory of the great English astronomer was the correct one. Seen through the telescopes at a distance of only thirty or forty thousand miles, it became perfectly plain that the outer or darker ring as seen from the Earth was composed of myriads of tiny bodies so far separated from each other that the rayless blackness of Space could be seen through them.
"It's quite evident," said Redgrave, after a long look through his telescope, "that those are rings of what we should call meteorites on Earth, atoms of matter which Saturn threw off into Space after the satellites were formed."
"And I shouldn't wonder, if you will excuse my interrupting you," said Zaidie, "if the moons themselves have been made up of a lot of these things going together when they were only gas, or nebula, or something of that sort. In fact, when Saturn was a good deal younger than he is now, he may have had a lot more rings and no moons, and now these aerolites, or whatever they are, can't come together and make moons, because they've got too solid."
Meanwhile the Astronef was rapidly approaching that portion of Saturn's surface which was illuminated by the rays of the Sun, streaming under the lower arch of the inner ring.
