SNC’s DSG Module Design – Element Overview

•Power and Propulsion Element (PPE)

o Aerojet Rocketdyne 50 kW Solar Electric Propulsion Module featuring four 13 kW AEPS thrusters

o Logistics and Control Module, derived from SNC’s Cargo Module on CRS2, provides avionics, GN&C, pressurized volume for cargo delivery and habitable volume

o Two PPE included in DSG architecture to increase power and propulsion capabilities, and for redundancy

•Large Inflatable Fabric Environment (LIFE)

o ILC Dover inflatable habitat provides significant

pressurized volume for long duration human

activity

o Minimal mass and volume for efficient packaging

in EELV 5-m fairing

o Inner core supports integration of ECLSS

systems, passage through element

•Extended Logistics and Control Module (ELCM)

o Evolved from LCM to increase cargo carrying

capabilites

o IDSS compatible ports for visiting vehicles

o Airlock for DSG EVA

SNC Deep Space Gateway System Concept

The SNC DSG is a flexible, modular architecture designed to support crewed or autonomous operations in cislunar space

Our solution can be assembled using 4 SLS and/or commercial launches and features 3 unique platforms

The building block approach provides for incremental build up and test, and evolution of in-design elements and subsystems

The modular architecture supports buildup, test and deployment of the Deep Space Transport (DST) through reuse of elements

We minimize development costs by extensive re-use of CRS2 components and subsystem technology, and AEPS technologies Our full scale ground prototype will confirm the proof-of-concept,

demonstrate interfaces between core technology elements and create a

“walk through” experience that fosters program adoption by government

seniors

The Deep Space Gateway (DSG) is envisioned to prove critical technologies for a human-tended, cislunar outpost for future lunar and deep space exploration.
