SAGE IV Pathfinder

Completed Technology Project

Project Introduction

SAGE IV Pathfinder
Utilizing a unique, new occultation technique involving imaging, the SAGE IV concept will meet or exceed the quality of previous SAGE measurements at a small fraction of the cost. The results of two Engineering Design Studio (EDS) sessions already held at NASA Langley have been used to finalize a mission design, and a ROSES Instrument Incubator Program (IIP) proposal has been submitted. Preliminary hardware and embedded control firmware and software development is currently underway. Of particular importance is a rework and finalization of the telescope design, which was deemed to be insufficient with respect to stray light mitigation after the EDS. The SAGE IV telescope design work is currently under contract to Quartus Engineering (forward funded from FY16 resources) and will be completed by the end of January 2017. We will also finalize work related to a laboratory demonstration of the filter wheel mechanism. Some resources are required to continue to support critical work and personnel at NASA larc between the start of FY17 and the anticipated start of an IIP effort. Under an IIP, a fully functional SAGE IV Pathfinder ground demonstration unit will be developed and built with CIF/IRAD having played a pivotal role in enabling this innovation and future mission.
