Exploring the remote and enigmatic outer planets of our solar system, such as Neptune and Uranus, is a pivotal part of NASA’s exploratory objectives. These ice giants are key to unlocking the mysteries of solar system origins and evolution. However, the challenge of high expense, extensive travel durations, and limited opportunities for mission launches has severely curtailed exploration beyond the asteroid belt over six decades of spaceflight. This NIAC-funded project presents a revolutionary mission architecture, capable of overcoming these barriers through the use of a ScienceCraft, opening doors to frequent and cost-effective missions to the outer planets. A ScienceCraft is an innovative integration of a scientific instrument with the spacecraft structure itself, resulting in a unified, lightweight construction.
Utilizing groundbreaking technology, a quantum dot spectrometer, devised by principal investigator Sultana, is produced directly onto the spacecraft’s solar sail. This integration leads to a novel spacecraft design that not only propels through space but also utilizes its structure for scientific measurement, a significant step forward in the exploration of the outer solar system. The ScienceCraft concept presents a cost-efficient and launch-flexible platform, ideal for hitchhiking as a secondary payload. Capitalizing on these advantages, a mission to Triton, Neptune’s captivating moon, is proposed within an optimal timing window closing around 2045. This mission aims to delve into Triton’s atmospheric, ionospheric, plume activity, and internal characteristics.
The first phase encompassed a comprehensive feasibility analysis for a Neptune-Triton mission leveraging ScienceCraft, pinpointing essential technologies and challenges to tackle. The upcoming second phase is dedicated to further maturing this mission concept, advancing critical technologies, addressing Phase I challenges, and outlining a strategy for SCOPE’s future realization.
