1 Introduction and Background NASA supports public-private partnerships for achieving its strategic goals and objectives for expanding the frontiers of knowledge, capability, and opportunities in space. In fact, an important part of NASA’s strategy is to stimulate the commercial space industry while leveraging those commercial capabilities through public-private partnerships and potentially through future contracts to deliver mission capabilities at lower costs. The second Next Space Technologies for Exploration Partnerships (NextSTEP)-2 omnibus Broad Agency Announcement (BAA), NNH16ZCQ001K, solicits proposals through appendices in areas including, but not limited to:

• Studies to support mission architecture definition;

• New approaches to rapidly develop prototype systems;

• Demonstration of key capabilities;

• Validating operational concepts for future human missions beyond low-Earth orbit; and

• End-to-end design, development, test, and in-space evaluation of future flight systems.

As part of NASA’s approach for expanding human presence beyond low Earth orbit and consistent with the NASA Transition Authorization Act of 2017, a Deep Space Gateway and Transport (DSG&T) concept is being examined. A Power and Propulsion Element (PPE) would be the initial element in the Deep Space Gateway (DSG) concept and would conceptually launch as a co-manifested payload with the Orion crewed vehicle on the Space Launch System (SLS) on Exploration Mission-2 (EM-2).

This NextSTEP-2 Appendix C builds upon prior efforts in flight demonstration and mission use of advanced solar electric propulsion technologies for NASA and other potential partner applications and NextSTEP-2 partnership concept and development efforts. The mission concept activities for first use of advanced solar electric propulsion in the Asteroid Redirect Robotic Mission provides a useful common point of departure for examining requirements and concepts of operations and risk.

The first appendix under NextSTEP-2, Appendix A, focuses on developing deep space habitation concepts, engineering design and development, and risk reduction efforts leading to a habitation capability in cislunar space. This NextSTEP-2 Appendix C is complimentary to the efforts sought under NextSTEP-2 Appendix A on habitation, and specifically seeks proposals for areas necessitating further study in this timeframe to assist in the development of the PPE concept and approach. Additional information on NextSTEP-2 is available at the NextSTEP Website:

www.nasa.gov/nextstep

2 The Mission of the Deep Space Gateway (DSG) Power and Propulsion Element (PPE)

The DSG concept being examined is a crew-tended spaceport in lunar orbit that would serve as a gateway to longer duration missions and enhanced capability to extend human presence. In addition to the power and propulsion functions, a PPE would host communications functions and http://www.nasa.gov/nextstep potentially a partner provided payload or system. A complete set of PPE capability descriptions are provided in Attachment B to this Appendix.

2.1 Objectives

The objectives of this solicitation are to seek proposals from industry for the conduct of studies specifically focused on areas of differences between previous architectures/configurations for 50kW-class SEP demonstration and the envisioned DSG PPE capability.

Specific objectives NASA would like to accomplish include:

• Identification and understanding of areas of significant potential synergies between the PPE and current commercial capabilities. This includes innovative ideas for business models, including intellectual property, asset ownership, and timing of delivery of the asset and/or services to the Government.

• Evaluate and understand driving technical differences and implications between prior concepts and approaches developed under the Asteroid Redirect Robotic Mission (ARRM) and the proposed concept for the PPE, such as implications to meeting reference technical requirements and/or drivers for validating a concept of operations.

• Identification and understanding of areas of significant potential synergies between the PPE and future commercial capabilities. This includes innovative ideas for future business models, including intellectual property, asset ownership, and timing of delivery of the asset and/or services to the Government.

• Identification of options and potential approaches to meeting potential requirements and to contributing reliability and verification/validation data for a PPE to a human rated DSG system.

3 Description of Study Topics

All Offerors shall respond to the following topics in their proposals. The topics are grouped into two Contract Line Items identified as CLIN 1 and CLIN 2. Please refer to Attachment B, PPE Capabilities Summary (PPE High Level and Second Level). Note, Attachment B will be forthcoming.

The CLIN 1 topics to be addressed are:

• An approach for the PPE design and verification to provide the required functionality with sufficient reliability, fault protection and availability to operate as part of a human-rated system for all crewed mission phases. This could include the use of relevant data from on-orbit operation of subsystems if the PPE use case is applicable, sufficient number of units and cumulative operating have been achieved, and failure modes are sufficiently well understood to establish the confidence and margin needed for use as part of a human-rated system.

• The use of standards, specifications, and engineering processes to assure a PPE design that cost-effectively minimizes the probability of the occurrence of failure modes through the application of selective redundancy, factors of safety, or other design margins as necessary for operation as part of a human-rated system.

• An approach to providing and validating propulsive and non propulsive attitude control for a DSG with a range of possible stack configurations. Include an assessment of:

o The integrated stack envelope mass versus the contractor’s standard payload and accommodation of the same by contractor’s bus primary structure o Whether new structure is added below the existing bus structure, or if new primary structure would have to reside inside the bus.

• An approach to performing propulsive orbital maintenance maneuvers for entire DSG integrated with a range of possible stack configurations.

• An approach for PPE operation during the rendezvous and docking of crewed and uncrewed visiting vehicles including Orion with a DSG.

• An approach for the PPE to provide a DSG with uncrewed autonomous orbit-transfer capability.

• An approach for the design, development, and operation of a high-reliability PPE power generation and power transfer capability as part of a DSG.

o Exploration power standard not met (98-136 V) if applied to internal PPE power architecture

• An approach to hosting two IDSS passive interfaces and assessment for how this drives system technical risk, cost, and schedule.

• An approach to addressing the minimal 15 year PPE operational lifetime requirement.

• An approach to long-term autonomous operation in the cis-lunar environment including fault monitoring, detection, and handling.

• An approach for the PPE to provide high-reliability communications for a DSG.

• An assessment of the impacts of accommodating an optical communication demonstration onboard the PPE.

• An assessment of the impact of the application of NASA defined engineering design & construction standards, interoperability standards, and safety and mission assurance standards that may be proposed for the PPE in a human rated DSG.. Please refer to 8705.2C, Human-Rating Requirements for Space Systems, Chapter 3.

The CLIN 2 topics to be addressed are:

• Options for cost share/cost contributions.

• An assessment of impacts of acquiring high power, high throughput EP strings as part of the commercial bus, rather than through a Government Furnished Equipment route.

• An approach to providing accommodations of potential (international or domestic partner provided) hardware such as robotic fixtures, science and technology utilization and other possible elements.

• An approach to addressing ability to manage batteries charge and discharge during different eclipse durations.

• Conceptual layout including identification of any potential clearance or blockage issues which may exist for the PPE.

• A PPE approach that is tolerant to crew exercise and implications of extended crew stay durations.

• An approach to a PPE lunar communication system that could operate as part of a larger and separate system from the DSG as an additional proving ground segment separate from the PPE.

• An approach to avionics, time-triggered Gigabit Ethernet, internal modular avionics & software.

• An approach to PPE Assembly, Integration and Test, including a description of industry practices and available data and identification of unique Government capabilities if needed.

• An approach to extensibility and possible future PPE configurations or use of systems/subsystems for future exploration vehicles/activities.

• An approach to extensibility and possible future PPE configurations or use of systems/subsystems for possible future commercial vehicles/activities.
