Drakkar Field Generator

The Drakkar Field Generator is the ship’s forward defense against the hazards of interstellar travel. By turning otherwise invisible particles into a managed stream along the hull, it helps keep the Drakkar habitable at near-light speed; when a collision destroys one of its modules, that protective system becomes the center of a lethal repair emergency.

Function and Protective Role

Space around the Drakkar is not empty. Each cubic meter contains roughly a hundred thousand hydrogen atoms, harmless at rest but dangerous when encountered at nine-tenths the speed of light. The generator, mounted in the ship’s nose, shunts those atoms aside and turns them into a continuous stream of cosmic rays just above the hull. With the field working, the stream remains outside, allowing the people aboard to travel safely inside.

Dust presents a different, recurring test. The ship passes through about 270 million cubic meters of space every second, so even a grain occurring only once per million cubic meters can strike the hull with regularity. Most grains carry enough charge for the generator to funnel them along the surface and away. The few that escape this deflection produce tiny explosions against the nose cone, whose thick ablative armor is designed to withstand decades of ordinary wear. That protection has a limit, however: the armor is not built to absorb an impact from anything much larger than a dust grain.

Collision and System Failure

The limit of the Drakkar Field Generator’s protection is exposed when an object larger than a dust grain strikes the ship. Its identity cannot be determined: the impact reduces it to quarks and gluons. Engineers estimate its mass at fifteen to twenty grams, calculated from the armor volume vaporized and the kinetic energy the Drakkar lost. The small mass is deceptive at the ship’s speed; the collision punches through the nose cone and destroys one of the field-generation modules.

The jolt sends unsecured people and objects flying into the forward bulkheads. Several crew members break arms, one suffers a serious concussion, and Mickey sprains an ankle against the edge of a table. Those injuries quickly become secondary to the breach. With a hole in the nose cone and a module gone, hard radiation floods twenty percent of the ship’s interior. The generator is no longer simply a shield against the routine particle stream: its failure turns the ship itself into a dangerous place to remain.

Systems Engineering head Maggie Ling summons Mickey to the machine shop, the nearest safe compartment to the nose-cone access hatch. Engineers put him in a vacuum suit and give him a replacement unit: a half-meter-square silver cube with two floating connector cables on one side and two maneuvering handles on the other. The suspected power coupling may be damaged, but there is no time to diagnose it; Mickey is told to replace the entire unit and retrieve the old one if possible. The access compartment is open to space, and, while the field remains down, Mickey will receive a lethal full-body radiation dose every three and a half seconds.

The danger is not presented as an instantaneous death sentence. Maggie explains that the body takes time to shut down even after receiving many times a fatal dose, leaving Mickey enough time to upload before he dies, provided a grain does not hit him directly. His next instantiation is already being prepared in the tank. The repair therefore depends on the same system that makes him expendable: the field must be restored before radiation kills him, while his experience of the emergency must be preserved through an upload.

Replacing the Module and Restoring the Field

The damaged generator was one of six identical cubes arranged in an array. From the access compartment, Mickey Barnes could identify the failed unit by the black-rimmed hole, two or three centimeters across, punched through its top. A larger opening in the compartment roof admitted a beam of bluish light, which fell directly on the wrecked cube. As Mickey worked to disconnect and remove it, his skin began to burn; when he positioned the replacement, his head passed through the beam, intensifying the bodily cost of the repair.

Maggie Ling guided the final connection over the comm. When the connector clicked into place, she confirmed that the field had been reestablished and told Mickey to relax while someone came to retrieve him. But the system’s restoration did not make the exposure disappear. Too weak to open his helmet seals, Mickey floated in the compartment, shaking and in pain, until the crew pulled him back inside. He was uploaded before he died so that the knowledge and experience acquired during the emergency would survive with his next instantiation.

By the time Mickey2 emerged from the tank, the generator was functioning and conditions aboard the Drakkar had largely returned to normal. The protection had come back, but the collision’s consequences remained: thirty-four people were suffering varying degrees of radiation poisoning, and the hole in the armor left the ship vulnerable to another grain striking in the wrong place. The generator’s restoration was therefore only one part of recovery. As soon as Mickey2 was conscious and functioning, Maggie’s team sent him outside in another vacuum suit, carrying emergency patch nanites to repair the hull.

Residual Exposure and the Hull

Restoring the Drakkar Field Generator stopped the radiation emergency inside the ship, but the damaged nose armor remained a breach in the protection the field was meant to support. The generator now channeled a stream of protons along the hull, with its greatest intensity about two meters from the surface. Maggie Ling judged that Mickey2 might keep his exposure low enough to survive if he stayed close to the ship and avoided being struck by another grain. She sent him crawling roughly a hundred meters from the forward air lock toward the impact point, using small attractors on his palms and knees rather than relying only on boot locks.

The approach made the field’s protective effect tangible as a hazard. With about twenty meters left, Mickey began seeing flashes of light; by the time he reached the hole, his vision was blurring and his mouth tasted of iron. The generator had been restored, but its proton stream could not repair the armor: Mickey still had to apply emergency patch nanites directly to the damaged hull, under the same conditions that made the original module replacement lethal.
