ROSES25: A.15 BiosphereThe National Aeronautics and Space Administration (NASA) Science Mission Directorate has issued the ROSES-2025 solicitation, specifically for program element A.15 Biosphere, under solicitation number NNH25ZDA001N-BIOS, with a revised deadline structure introduced on July 20, 2026. This program requires a two-step proposal process, where a compliant Step-1 proposal must be submitted by September 4, 2026, to be eligible for Step-2 submission, which is due on November 6, 2026. Proposals failing to meet the Step-1 requirement will be returned without review. The Step-2 technical, scientific, and management section is limited to 12 pages and must follow specific formatting rules: 1-inch margins, no more than 5.5 lines per inch, and 15 characters per inch, printed on US letter-sized pages. Proposers are strongly encouraged to use the Earth Science Division template for the summary table of work effort. This program utilizes dual anonymous peer review, requiring the technical proposal to be stripped of all identifying information and submitted as a separate document from the “Expertise and Resources Not Anonymized” file containing CVs, current and pending support, and personnel details. A separate “Total Budget” PDF must also be submitted, excluding salary and overhead information. All principal investigators and co-investigators spending 10% or more time on the project must complete NASA-accepted research security training through the NSF or SECURE Center platforms by August 5, 2026. Proposals must be submitted electronically via NSPIRES, with Grants.gov submissions permitted only if requested at least 30 days in advance. Submission files are limited to searchable, unlocked PDFs under 20 MB in size, with all supporting documents embedded or submitted as separate files. Awards are typically grants or cooperative agreements of up to five years, with a standard duration of three years, and are subject to NASA’s Grants and Cooperative Agreement Manual. Organizations must maintain active SAM.gov registration and provide a Unique Entity Identifier; CAGE codes are not required. Proposal evaluation prioritizes relevance as a mandatory threshold, followed by intrinsic merit and cost reasonableness, using a trade-off approach that does not permit lowest-price technically acceptable selection.

Commercial Low Earth Orbit (LEO) Destination Contract (CLDC) Technical LibraryThe Commercial Low-Earth Orbit (LEO) Destination Contract (CLDC) Technical Library is a non-solicitation informational resource established by NASA Johnson Space Center to provide industry with access to evolving technical standards, requirements, and capabilities relevant to future commercial LEO destination development. The library is maintained through periodic Data Drops that release uncontrolled and controlled technical documents, including revisions to standards such as CLDP-REQ-1130 and CLDP-STD-1106, along with facility capability profiles from Johnson Space Center and White Sands Test Facility. An Excel index file, continuously updated with each Data Drop, serves as the primary catalog for tracking document versions and classifications. Access to export-controlled materials requires formal submission of the CLDP Export Control Request Form and compliance with U.S. export regulations, including the requirement for foreign nationals to have an Individual Technology Transfer Control Plan and Non-Disclosure Agreement. The library remains accessible to industry for reference, but it does not constitute a solicitation, request for proposal, or binding commitment by the government. The CLDC acquisition itself is currently on hold, with NASA shifting focus to supporting industry development through funded Space Act Agreements while continuing to refine technical standards for a future FAR-based acquisition. All updates and future solicitations will be posted exclusively on www.sam.gov.

DRAFT Solar System Exploration Research Virtual Institute Cooperative Agreement Notice-5 (SSERVI CAN-5)The Solar System Exploration Research Virtual Institute Cooperative Agreement Notice-5 (SSERVI CAN-5), solicitation number NNH26ZDA013J, issued by NASA's Science Mission Directorate, invites proposals for multidisciplinary research and workforce development initiatives aligned with NASA’s solar system exploration goals. Submission follows a two-step process: a Step-1 proposal, which is mandatory for eligibility to submit a full Step-2 proposal, serves as a preliminary, anonymous summary requiring only the Principal Investigator’s details, team members, project title, and a brief description. Step-1 proposals are treated as competition-sensitive and must be submitted through NSPIRES, with all participating individuals and institutions preregistered in NSPIRES and the System for Award Management (SAM), a process that may take up to 30 days. Step-2 proposals must be structured into three required PDF volumes—Volume A (anonymized technical content), Volume B (non-anonymized administrative and personnel information), and a separate total budget file—with an optional fourth file for High-End Computing resource requests. Volume A is limited to 55 pages total across sections including the Executive Summary, Research Plan, Open Science and Data Management Plan, Workforce Development Plan, Fieldwork Plan, and Citizen Science/Science Activation Plan, all subject to strict formatting rules including font size, margins, and character density. Evaluation is based on a trade-off methodology, with Volume A carrying 100% of the technical score weighted toward Scientific and Technical Merit (70%), Workforce Development (15%), and Citizen Science/Science Activation (15%). Volume B is assessed qualitatively and non-additively; deficiencies here may disqualify otherwise strong proposals, even if Volume A scores highly. Key compliance elements include disclosure of foreign collaboration via endorsed letters, exclusion of any involvement with China or Chinese-owned entities, reporting of current and pending support using NASA SciEncv format, completion of research security training for senior personnel, and adherence to data management standards under 2 CFR 200.455 and NASA’s FAIR data principles. All proposals must be submitted electronically by the NSPIRES deadline, with no physical submissions accepted. Funding is estimated at $9 million over five years, with awards anticipated approximately 12 months after the Step-2 deadline, and applicants assume all financial risk for costs incurred prior to the official award start date.
