Space Station Dogged By Oxygen Problems

Alien54 writes "All of the Russian made Elektron oxygen generators on the International Space Station have failed. The three Elektron units on board the space station are the last of their kind. The company that manufactured them has gone out of business, and the engineer who almost single-handedly made the final adjustments of flight units died several years ago. Reportedly he retained some 'trade secret' about the final adjustments of the devices -- and it died with him. But NASA is not alarmed."
