Computer based control of the Superfluid Helium On-Orbit Transfer Space Shuttle experiment

Abstract

Ground software that is being developed for the control of the Superfluid Helium On-Orbit Transfer (SHOOT) project is discussed. Special attention is given to two software development projects for SHOOT support: (1) the SHOOT Command and Monitoring System, which will provide a real-time highly interactive interface for the SHOOT principal investigator to control the experiment and to analyze and display its telemetry; and (2) the SHOOT Aft Flight Deck Operating System, which is comprised of several monitoring programs to give the astronaut mission specialist on-orbit visibility into SHOOT systems, and an intelligent-rule-based system that will control a He transfer without ground intervention. Major accomplishments of the SHOOT project to date include two successful interface tests with the Goddard Space Flight Center developed breadboard electronics and prototype software.
