********************** NOTICE TO ALL INTERESTED PARTIES *********************

Section 1 - Overview

The National Aeronautics and Space Administration (NASA) is seeking information from U.S. and international commercial providers on support for the recently redefined Artemis III mission. NASA is particularly interested in innovative, secondary communications capabilities that can enable robust, high rate data return from the Orion crew vehicle during operations in Low Earth Orbit (LEO).

This Request for Information (RFI) is issued by NASA’s Moon to Mars (M2M) Program, and aims to identify mature services and user terminals that can augment Orion’s primary communication system. Respondents are invited to submit end-to-end system concepts that could provide continuous, high bandwidth transmission of mission data in the dynamic LEO environment and contribute to the success of crewed space exploration under the Artemis program.

Section 2 – RFI Overview

2.1 The Artemis III Mission

The Artemis III mission will launch crew in the Orion spacecraft atop the Space Launch System (SLS) rocket into a Low Earth Orbit (LEO) to test rendezvous and docking capabilities between Orion and the commercial spacecraft needed to land astronauts on the Moon. Artemis III will test integrated rendezvous and proximity operations between the Orion spacecraft and one or both commercial lunar landers provided by SpaceX and Blue Origin.  

The Artemis III mission profile is still being finalized.  For the purposes of responses to this RFI, the following Ground Rules and Assumptions can be considered:

• Summer 2027 Artemis III Mission
• Orion will be around a 250 nmi orbit with a 33 deg inclination
• Non-Critical (Crit 3) Application

2.2 Service and Integration Expectations

The Artemis III mission profile moving to LEO is introducing new challenges to the Orion vehicle, one being a reduced data rate for the primary communication system.  In addition, M2M seeks to receive live 4K imagery during rendezvous and docking operations, and downlink of large files in other phases of flight. To meet these demands, a secondary communications system is being evaluated for inclusion in the Artemis III Orion configuration.  It is anticipated that, to meet these requirements, the system must provide near continuous communication with a return link of at least 12 Mbps.

Given the short timeline, availability of hardware and ease of integration into the Orion vehicle is a significant consideration.

Performance Objectives

• Near continuous communication (goal: > 75%)
• > 12 Mbps Downlink (goal: 20-50Mbps)
• > 500 kbps Uplink (Desired to support Class 2 CFDP, not a system requirement)
• System must provide a broad field of regard or steerable antenna/aperture
  • Orion has many driving attitude constraints so precise vehicle pointing of a fixed antenna/aperture is not available

Orion Vehicle Integration

Given the short timeline, ease of integration into the Orion vehicle is a significant consideration. Key design parameters include:

• Data Interface: Ethernet
• Hardware Control & Telemetry Interface: Ethernet
• Power Interface: 28 VDC, < 90W max (goal)
• Mass: < 20kg (goal)
• Max Volume: 22” x 18” x 18” (goal)

Implementation Options

Both internally configured and externally mounted implementations will be considered.

• Parameters if externally mounted on Orion Crew Module Adapter
  • Mounted under Service Module (SM) fairing during launch
  • Assumes system is a single assembly, mounted on a plate or pallet
  • No active cooling
  • Flight Hardware delivery needed in fall 2026. (assume ATP + 4 months)
    • Location is not accessible after SM fairing installation during I&T
  • Assume typical launch vehicle and LEO environments
• Parameters if internally configured by Orion crew
  • Stowed during launch and setup by the crew
    • Multiple separate components can be assumed
    • Assume antenna placed against window, not integrated into spacecraft
  • Flight Hardware delivery needed in early 2027. (assume ATP + 8 months)
    • Crew cabin can be accessed later in I&T flow than Service Module
  • Assume soft stow launch and pressurized cabin environments

Testing

• It will be essential to perform Spacecraft (End to End) data flow test prior to launch

Section 3. Requested Information

NASA invites detailed responses from industry on existing or planned capabilities that are available to support NASA’s emerging needs for Orion in LEO during Artemis III. Respondents are encouraged to submit existing documentation, such as Interface Control Documents (ICDs), Service Level Agreements (SLAs), or User Guides, where available.

Information provided will be used solely for internal Government planning, market research, and acquisition strategy development purposes. NASA will not publicly release company-specific data or estimates.  

Response to questions can be marked proprietary or confidential information.  However, industry respondents are encouraged to deliver information such that it can be openly shared with the NASA stakeholder community and critical industry partners involved with Orion vehicle, enabling NASA to move quickly to assess and execute on any next steps.
