Development of the thermal interface between the Dragonfly Mass Spectrometer and the DrACO Sample Delivery Carousel

Le résumé fourni par la source

Icy celestial bodies are an exciting new frontier for surface exploration and in-situ sampling and analysis. These destinations are inherently cryogenic in nature, and each body presents unique challenges related to thermal design. The Dragonfly mission to Titan is one such example. One of the most important requirements of a sampling system is to preserve the integrity of the surface material. The interface between the Dragonfly Mass Spectrometer (DraMS) and the Drill for Acquisition of Complex Organics (DrACO) Sample Delivery Carousel (SDC) is complicated by several competing requirements. Development of this interface has required the use of new enabling technologies such as additive manufacturing to achieve a successful design. Additionally, test methodologies were developed to simulate Titan convective conditions with Earth gravity. This overview of the DraMS Cryogenic subsystem will show how the design meets all the requirements of the interface and preserves integrity of Titan surface samples.
