A year in orbit: ISS deployment tests radiation detectors for future space missions
The predawn darkness on a cool Florida night was shattered by the ignition of nine Merlin engines on a SpaceX Falcon 9 rocket. The thrust of the engines shook the ground miles away. From a distance, the rocket appeared to slowly rise above the horizon. For the cargo onboard, the launch was anything but gentle, as the ignition of liquid oxygen generated more than 1.5 million pounds of force. After the rocket had been out of sight for several minutes, the booster dramatically returned to Earth with several sonic booms in a captivating show of engineering designed to make space travel less expensive and more sustainable.

Boron-containing materials for which fabrication processes are described include boron dispersions in iron, boron-stainless steel alloys, and boron carbide-filled stainless steel tubes. Experience with both satisfactory and less-than-satisfactory materials and fabrication procedures is briefly documented. The present performance of boron carbide-filled tubes, sheathed to make a cruiform control rod, is satisfactory, and continuing improvements are expected.
