 What is Peter's mission aboard The Avenger?
THE AVENGER By STUART FLEMING Karson was creating a superman to fight the weird super-monsters who had invaded Earth. [Transcriber's Note: This etext was produced from Planet Stories Spring 1944. He had been dead for some time now, but the dark blood was still oozing from the crushed ruin of his face, trickling down into his sodden sleeve, and falling, drop by slow drop, from his fingertips. It was I who had changed: something inside me was dead, like the machinery, and like Peter. I do not think it was what Peter called an emotion; and yet it had nothing to do with logic, either. It was just an emptiness—a void that could not be filled by eating or drinking. I did not even wish that Peter were not dead, for reason had told me that he had to die. Young Peter Karson put the last black-print down and sighed with satisfaction. His dream was perfect; the Citadel was complete, every minutest detail provided for—on paper. In two weeks they would be laying the core, and then the metal giant itself would begin to grow, glittering, pulsing with each increment of power, until at last it lay finished, a living thing. Then there would remain only the task of blasting the great, shining ship out into the carefully-calculated orbit that would be its home. He could see, too, the level on level of laboratories and storerooms that filled its interlocking segments; the meteor deflectors, the air renewal system, the mighty engines at the stern—all the children of his brain. Out there, away from the muffling, distorting, damnable blanket of atmosphere, away from Earth's inexorable gravitational pull, would be a laboratory such as man had never seen. The ship would be filled with the sounds of busy men and women, wresting secrets from the reluctant ether. A new chemistry, a new physics; perhaps even a new biochemistry.

 To seek a solution to the aliens out in space.  To take the embryos with him and start a new life for humans.  To mutate embryos until they come across someone who can fight the aliens.  To seek out a "superman." Someone who can face the aliens for them.
