We demonstrate that a low-cost spacecraft bus based on the Propulsive ESPA architecture, launched as a directed facility alongside a mission to the outer solar system, enables innovative and viable SIMPLEx-class missions to the outer solar system and achieve high-value science objectives. As a case study, we present a Propulsive ESPA bus that could be launched with the Dragonfly mission toward the Saturn System and carry two small spacecraft weighing up to 130 kg each. We advocate a mission architecture that enables delivering multiple small missions to the Saturn System on a stand-alone Carrier-Relay Spacecraft (CRSC) that flies independently, and poses zero impact on the Dragonfly Mission. To accommodate this architecture, the launch vehicle will require an upgrade from Dragonfly's notional Atlas V 411 to Atlas V 541. Raising the SIMPLEx cost cap from the current $55M, and excluding Phase E costs will also make outer-planet missions viable in the SIMPLEx program. We have identified multiple high-value mission concepts that fit within the 130 kg limit. As examples, we present concepts for Saturn Probe, Saturn Ring In-Situ Explorer, Magnetospheric Explorer, and Enceladus Plume Sampler. |
