Russian space module 'in need of more protection.'

Article Abstract:

The US National Research Council reports that sections of the international space station that was built by Russia will have to be protected against damage from orbital debris. Since possible collisions with large objects have been increased from six to 10 times a year, spacewalking astronauts may need to fit the Russian components with additional shielding to protect the station's plumbing and other exposed hardware. Although smaller space objects will be pulverized once they hit the shields on the outer surface, objects larger than 10 cm will have to be evaded by using US military surveillance cameras to monitor orbiting debris.

Space centrifuge deal may mean job losses at NASA

Article Abstract:

Japan's offer to build a centrifuge and associated hardware, including an animal-holding facility for biological research has impelled NASA to stall its own plans for it. This may result in job losses at the Agency's Ames Research Center in California. In exchange for the centrifuge, Japan will receive a free launch of its Japanese Experiment Module in 2000. The barter will solve a short-term financial problem for NASA which has already spent $50 million to develop the facility. It is unclear whether the Japanese agency, NASDA will take over the work of the Ames Research Center.

Superconductivity devices are headed into space

Article Abstract:

The Naval Research Laboratory will shoot two High Temperature Superconducting Space Experiments (HTSSE) into space, HTSSE 1 in 1993 and HTSSE 2 in 1996. These $20 to $25 million experiments will try out high temperature superconductors as materials that will allow satellite components to be lighter, less bulky and yet stronger. HTSSE 1 will assess each superconductor's performance including the effects of radiation. HTSSE 2's goals include checking complete superconductor-containing subsystems.
