NASA's proposed Enceladus Orbilander mission represents a significant advancement in astrobiology exploration. Unlike traditional missions that separate orbiter and lander components, the Orbilander concept integrates both functionalities into a single spacecraft. This innovative approach aims to maximize scientific return by enabling comprehensive studies of Enceladus's surface and subsurface environments. The mission is designed to conduct detailed reconnaissance of the moon's icy surface, analyze plume samples, and assess the habitability of its subsurface ocean. By combining these capabilities, the Orbilander seeks to address fundamental questions about the potential for life beyond Earth. en.wikipedia.org
The Enceladus Orbilander mission is currently in the conceptual phase, with a proposed launch in October 2038. The spacecraft is envisioned to perform a series of flybys of Saturn's moons, utilizing gravity assists to adjust its trajectory before entering orbit around Enceladus. Once in orbit, the Orbilander would deploy a lander to the moon's surface, allowing for in situ analysis of surface materials and direct sampling of plume emissions. This mission aims to build upon previous discoveries, such as the detection of organic compounds in Enceladus's plumes, by providing more detailed and direct evidence of the moon's potential to support life. en.wikipedia.org
