Kath Two was snapped out of her work reverie by a mild shift in their tone of voice. Now they were talking about something important. Not in an urgent or concerned way. A glance at the display told her what it was: they were nearing the ring, which meant that they were about to lance through the twenty-kilometer-wide gap between two space habitats. There was no reason that this should be a problem, but it was the sort of feat that focused one’s attention and brought a discernible edge to one’s voice.
She reached up and found the lever on her varp that activated an opaque screen over the lenses: essentially, a blindfold. Her view of the cabin was now blocked. The only things she could see were those being projected into her eyes by the varp. At the same time she activated an application that gave her the ability to see the flivver’s surroundings as if she were floating adrift in space. The same service could have been provided by a bubble of glass on the flivver’s hull, but it wouldn’t have been as good. It would have exposed the user’s head to cosmic radiation, and the contrasty light would have made it difficult to see certain things. The varp, on the other hand, played games with the light’s dynamic range so that bright things were less so while dim things were bright enough to see; it gave everything a luminous warm quality that did not exist in reality. It was so far superior to looking at the world directly that many space suits eschewed transparencies altogether and just encased the wearer’s head in a radiation-shielded dome with a varp on the inside.
She was now “looking” at an enhanced view of the universe from their current location, which was just inside, but rapidly approaching, the habitat ring.
The ring was spinning past them. It was a little like being on the inside of a carousel watching the horses wheel by, except that instead of horses, these were space habitats as much as thirty kilometers across, and they were moving at three thousand meters per second.
The task was to shoot between two of them without getting hit. By the standards of orbital mechanics it was no great feat, but it looked shockingly dangerous, and as such it was great fun to watch. As Kath Two looked straight ahead, the habitats seemed to be whizzing across their path like the teeth of a buzz saw. But through an apparent miracle the flivver found a gap between two of them.
“Whip dock in three,” announced a synthesized voice, and Kath Two’s hands moved around to check the straps holding her into her seat.
An immense bullwhip was burgeoning toward them. Its general dimensions were about those of an exceptionally long Old Earth freight train, but instead of boxcars it was made up of many flynks coupled nose-to-tail into a chain.
If Rhys’s earlier preparations had gone according to plan—and Kath Two would have heard about it, were that not the case—then, several hours ago, the hundreds of flynks that lived in this whip station had begun to assemble themselves into a chain. When it had reached the desired length—which was a function of the specific mission to be performed—the chain had joined itself nose-to-tail into an endless loop and gone into motion, driven by a simple linear motor in the whip station. It had formed an elongated oval known as an Aitken loop and then devoted some time to tweaking its shape and dialing in its exact velocity. Flynks were simple beasts, consisting mostly of structure: solid aluminum cast into certain shapes. Each flynk had a knuckle amidships, enabling it to bend freely in both directions—in mechanical engineering terms, it was just a heavy-duty universal joint. Fore and aft it had couplers that enabled it to form a strong, rigid connection with other flynks. Somewhere in all of that structure were a few grams of silicon that made it smart, and lines for carrying power and information down the length of the chain.
A few moments ago, word had gone out to one of the flynks that it should decouple from the one behind it. This had happened just as it was emerging from the whip station. At the instant the coupler had disconnected, the system had stopped being an Aitken loop and started being a giant bullwhip. The niksht—a very old mispronunciation of Knickstelle, referring to the U-shaped bend at the apex of the loop—had begun to propagate away from the whip station, towing the free end of the whip behind it, accelerating as it went, and rapidly building to thousands of meters per second of velocity. This was the thing Kath Two saw in the VR: the elbow in the whip, coming right at them. The free end was concealed behind it, but she knew that in a few moments it would come whipping around in a huge final burst of acceleration.
