Abstract
The Volatile Organic Analyzer (VOA) provided valuable data on the gaseous trace contaminants in the atmosphere of the International Space Station (ISS) from January 2002 through May 2003. The VOA has two analytical channels that provide redundancy, but fuse failures caused the loss of one channel in January 2003 and the remaining channel in May 2003. In early 2005 on-orbit diagnostics verified failed fuses, and in December 2005 the fuses were replaced during an inflight maintenance (IFM) session.
The VOA has provided data on the ISS atmosphere since it was reactivated in 2005. This paper summarizes the IFM procedures and presents the on-orbit data from 2006 that were used to revalidate the VOA.
