Planetary Flight Vehicles (PFV): Technology Development Plans for New Robotic Explorers [invited]

Abstract

The Vehicle Systems Program (VSP) of NASA’s Aeronautics Research Mission Directorate (ARMD) has been investigating the technologies necessary to enable new planetary science and exploration missions using Planetary Flight Vehicles (PFVs). PFVs bridge the gap between orbiters (global scale and limited resolution) and rovers (local scale and high resolution). PFVs enable data gathering of phenomena at a regional scale that is not attainable with current surface based robotic system concepts. An example of such is localized magnetic fields that may provide radiation protection for human explorers. This paper outlines the goals, objectives, perceived technical challenges, and technology development approaches as they relate to enabling planetary exploration technologies. The process used for prioritizing technology investments based on science and exploration requirements with state-of-the-art assessments is discussed. Highlights of recent accomplishments in the Vehicle Systems Program’s PFV technology development activities are also presented.
