NASA’s Artemis missions aim to establish a sustained lunar presence on and around the Moon. Communications and navigation technologies will be critical to enabling the safety, science, and operations of our astronauts and missions.NASA Solicitation Number: NNH16ZCQ001K-1_Appendix-Q-LUTNOMS
July 8, 2024 – Solicitation Released
Solicitation Overview
NASA’s long-term vision to provide for a resilient space and ground communications and navigation infrastructure in which space mission users can seamlessly “roam” between an array of space-based and ground-based networks has been bolstered by innovative studies delivered by industry through the Next Space Technologies for Exploration (NextSTEP) – 2 Omnibus Broad Agency Announcement vehicle. Initially, NASA seeks to create an interoperable architecture composed of a mixture of existing NASA assets and commercial networks and services. In the long-term, this will allow for a smooth transition to fully commercialized communications services for near-Earth users. The overarching goal is to create a reliable, robust, and cost-effective set of commercial services in which NASA is one of many customers.
NASA’s Commercialization, Innovation, and Synergies (CIS) Office has released a solicitation notice under the Next Space Technologies for Exploration Partnerships-2 (Next STEP-2) Broad Agency Announcement (BAA) to seek industry insights, innovative guidance, and demonstrations in the following two (2) Study Areas:
Lunar User Terminals Network Orchestration and Management System (NOMS) To support lunar surface operations, NASA is seeking state-of-the-art industry studies, system development, and demonstrations for a dual-purpose navigation and communication lunar surface user terminal. The terminal must meet technical requirements provided by the government to support lunar surface exploration plans and ensure interoperability with developed LunaNet and Lunar Communications Relay and Navigation System (LCRNS) standards. The requirements will be split into separate LunaNet Augmented Forward Signal (AFS) navigation receiver and communications transceiver capabilities. However, the development of a combined communications and position, navigation, and timing (CPNT) system capable of meeting the full suite of requirements is desired.
Additionally, NASA is seeking innovative industry studies and demonstrations on advanced Network Orchestration and Management Systems (NOMS) that effectively address NASA technical requirements aimed at controlling and interfacing with a globally distributed network of Satellite Ground Systems currently supporting the Near Space Network (NSN).
The resulting studies will ensure advancement of NASA’s development of space communication and exploration technologies, capabilities, and concepts.

Sol 4225: Sliding Down Horsetail Falls
This image was taken by Left Navigation Camera onboard NASA’s Mars rover Curiosity on Sol 4219 (2024-06-19 02:21:53 UTC). NASA/JPL-Caltech Earth planning date: Monday, June 24, 2024
This will be an important week for chemistry on our latest drill sample “Mammoth Lakes 2.” Curiosity’s primary goal today was a preconditioning of the SAM instrument in preparation for its chemical analysis. Due to the large amounts of power required by SAM, today’s science block was limited to one hour, although it grew a bit at the cost of next sol’s science allocation. Today’s planning only covers one sol (4225), as our usual Wednesday planning day will not have Deep Space Network availability. We will plan 3 sols on Tuesday as a result.
Over the weekend, the “Mammoth Lakes 2” drill sample was dropped off to CheMin for analysis. Mastcam change detection observations of “Walker Pass 2” and “Finch Lake” were begun and will complete on Sol 4225. Remote science on “Whitebark Pass,” “Quarry Peak,” “Broken Finger Peak,” and “Shout of Relief Pass” completed successfully. On Sol 4225, the focus for remote science was a ChemCam laser spectroscopic characterization and Mastcam imaging of “Horsetail Falls,” an area near the edge of the “Whitebark Pass” workspace slab. The Navcam image below shows the rough surface of “Horsetail Falls” as a stripe of dark rubbly material near the top just right of center edge of the light colored “Whitebark Pass” slab. “Horsetail Falls” is an example of bedrock texture diversity. This target is named for an iconic 270 ft waterfall emerging from Agnew Lake and easily seen from the June Lake Loop road. “Shout of Relief Pass” honors the 11000 ft pass on the Sierra High Route trail which is a gateway to much easier terrain for the next 25 miles of the trail. All targets in this area of Mount Sharp are named after the Bishop geological quadrangle in the High Sierra and Owens Valley of California. ChemCam RMI will also image an 11×1 mosaic of the nearby channel floor where there are interesting color variations. Atmospheric observations in this science block consist of a dust devil survey. In the next plan, SAM will complete its initial analysis. Based on the SAM and CheMin results, the team will then decide whether to do more chemistry at this intriguing location or continue our drive up Mount Sharp.
