Abstract

We describe advancements toward a portable tunable laser spectrometer (PTLS) wireless mesh network that can be applied for human exploration. These include mid-infrared diode lasers with the requisite reliability and traceability to be used for critical applications, a wireless mesh network of PTLS instruments capable of near real-time monitoring of environmental gases over the spatial domain of a space station, and tests of prototype PTLS systems demonstrating their capability for gas-phase measurements using the new high reliability lasers.
