Request for Information (RFI): Formal Learning and Abstractions for System Heterogeneity (FLASH)

Solicitation # DARPA-SN-27-17

The Defense Advanced Research Projects Agency (DARPA) Information Processing Techniques Office (IPTO) has issued a Request for Information (RFI) under solicitation number DARPA-SN-27-17 regarding Formal Learning and Abstractions for System Heterogeneity (FLASH). The objective is to gather research on operationalizing robustness in cyber-physical engineering systems by decoupling high-level system requirements from instance-level design details. Specifically, DARPA is seeking information on national-security applications that benefit from heterogeneous engineering solutions and techniques for the automated synthesis of high-assurance systems from formal specifications. Key technical goals include formalizing semantic invariants, developing models for functionally equivalent design instances with provable correctness, and co-generating assurance artifacts. This is a special notice and not a formal solicitation for proposals; therefore, responses are not offers and cannot form a binding contract. Interested parties must submit their responses by November 30, 2026, at 5:00 PM Eastern Time. While responses can be submitted at any classification level, those intending to provide classified information must send an unclassified notification to [email hidden] by November 13, 2026. Submission methods vary by classification: unclassified responses are sent via email, Controlled Unclassified Information (CUI) via DoD SAFE, and classified materials through approved channels such as the DARPA Savannah Network, JWICS, or Secure Integration Cloud. All submissions must adhere to strict marking and handling standards, including DoDI 5200.48 for CUI and EO 13526 for classified national security information.

Cattle Run Proposers Day Announcement

Solicitation # DARPA-SN-27-03

The Defense Advanced Research Projects Agency (DARPA) is hosting a Proposers Day for the Cattle Run program on November 10, 2026, in Arlington, Virginia. The program aims to enable cost-effective cislunar constellations by developing and demonstrating autonomous spacecraft that utilize solar sails or other renewable propulsion for long-duration maneuverability and station keeping. The project is structured in phases, beginning with the rapid development and launch of a demonstrator spacecraft below geosynchronous earth orbit to validate acceleration, vehicle control, and autonomous Guidance, Navigation, and Control (GNC), followed by the deployment of multiple spacecraft for cislunar operations. This event is a special notice and does not constitute a formal solicitation for proposals. Attendance is strictly limited to U.S. Citizens, who must submit a U.S. Citizenship Verification form during registration. Additionally, all attendees and potential proposers must meet CMMC Level 2 requirements, with verification performed via the Supplier Performance Risk System (SPRS) using a CMMC Unique Identifier. The Proposers Day will be conducted at the Controlled Unclassified Information (CUI) level and serves as a forum for program information, networking, and one-on-one sessions with the Program Manager, Mr. Steven Chambers. Registration deadlines are listed as November 4 and November 6, 2026.

Request for Information (RFI) for a Cislunar Space System (CSS)

Solicitation # 10302026-01

The Department of the Air Force is conducting market research via a Request for Information to inform the acquisition strategy for a Cislunar Space System (CSS). The objective is the rapid development and fielding of up to five space vehicles by late CY29 to serve as seed vehicles for a potential future proliferated cislunar constellation. The system requires a comprehensive solution including spacecraft buses, a ground segment for mission management and telemetry, launch integration for government-provided National Security Space Launch boosters, and ongoing operations and maintenance. Technical requirements specify a payload capacity of up to 2,000 kg, power thresholds between 1 kW and 3 kW, three-axis stabilization with 6-DOF thruster control, and the implementation of NSA Type-I encryption. The government is seeking low-risk solutions with minimal non-recurring engineering, prioritizing buses that have flown within the last three years or will complete system-level integration within 24 months. Design life thresholds are set at three to five years with 0.6 reliability, and end-of-life disposal must comply with Orbital Debris Mitigation Standard Practices. Based on the RFI responses, the government may award up to five Firm Fixed Price preliminary design study contracts. Evaluation of respondents will focus on technical, schedule, and production risks, as well as overall execution ability and prior domain expertise in cislunar-qualified vehicles. Responses must be submitted electronically by November 13, 2026, and include a completed Summary Response Template and a technical narrative limited to fifteen pages.

B--USGS Paired Bulk Mineralogy/Clay Analyses

Solicitation # 140GG027Q0021

The U.S. Geological Survey Geology, Energy, and Minerals Science Center requires specialized services for paired bulk mineralogy and detailed clay analysis of 58 samples using X-ray diffraction analysis. This work supports the Thermal Indices and AGGER projects by investigating pore network development and mineralogical transformations in the Lower Huron Member of the Ohio Shale. The scope includes quantitative mineralogical analysis of both crystalline phases and the clay fraction, with a specific requirement for detailed data such as clay type, abundances, Reichweite value, and percentage of smectite interstratification for illite and chlorite. Under solicitation 140GG027Q0021, the government has issued a sole-source determination in accordance with FAR 12.102(a), identifying QMinerals as the only source capable of meeting the technical requirements. This determination is based on the necessity for data continuity and valid comparability to historical XRD data, as well as the high level of analytical rigor required, which other commercial laboratories cannot provide. The contract features a two-month period of performance from the date of award, with all data deliverables required in excel spreadsheet format. Interested vendors must contact the contract specialist by 1:00 PM EST on November 10, 2026, to contest the sole-source intent.
