Opportunity Summary:
NASA Headquarters, through the Science Mission Directorate (SMD), issued this funding opportunity as an Astrophysics Explorer 2014 Mission of Opportunity (MO) Program Element Appendix (PEA), labeled NNH12ZDA006O APEXMO2. It was released as Amendment 9 to the broader "Second Stand Alone Missions of Opportunity Notice" known as SALMON 2 (NNH12ZDA006O). In plain terms, this is NASA opening a specific call for proposals for PI-led astrophysics investigations that can fly as a Mission of Opportunity under the Astrophysics Explorers Program, using the rules and structure defined by the SALMON 2 announcement plus the additional, more tailored requirements in this PEA.
The scientific purpose of the solicitation aligns with NASA's core astrophysics objectives: understanding how the universe works, how it began and evolved, and how to search for life on planets around other stars. Proposals are expected to be directly relevant to SMD astrophysics priorities and to fit within the Explorer "PI-led" model, where a principal investigator leads the mission concept and is responsible for delivering the science investigation within NASA's cost, schedule, and technical constraints.
The application window opened on September 17, 2014, and closed on December 18, 2014, with a required Notice of Intent to Propose due on October 15, 2014. The full solicitation text was made available through NASA's NSPIRES system (http://nspires.nasaprs.com/), and NASA also planned a preproposal conference in early October, with details hosted on the Explorers acquisition website (http://explorers.larc.nasa.gov/APSMEX). That conference was intended to clarify requirements, answer early questions, and help teams understand how to prepare compliant proposals under SALMON 2 and this specific appendix.
Eligibility was broadly open and described as "unrestricted," meaning NASA welcomed proposals from essentially any category of organization, subject to the detailed eligibility language in the full text. This included U.S. and non-U.S. entities, universities, nonprofits, industry, Federally Funded Research and Development Centers (FFRDCs), University Affiliated Research Centers (UARCs), NASA Centers, the Jet Propulsion Laboratory (JPL), and other government agencies. The listing indicates the opportunity used grant and cooperative agreement instruments, was categorized under science and technology research and development, and fell under CFDA 43.001 (Science). No cost sharing or matching was required.
NASA indicated an expectation to select one or two Missions of Opportunity to move forward into Phase B and then into later mission phases. However, the language also left room for NASA to select more than two investigations if multiple selectable proposals fit within the available budget when considered together. This is an important feature for teams: selection is competitive, but NASA preserved flexibility to maximize science return if funding and portfolio balance allow.
This PEA explicitly stated that it incorporated a number of changes compared with earlier versions of the Explorers Mission of Opportunity PEA under SALMON 2 and compared with the draft 2014 version. Because of that, NASA emphasized that proposers needed to read both the overarching SALMON 2 Announcement of Opportunity and this appendix carefully, and that proposals had to comply with all requirements, constraints, and guidelines across both documents. Practically, that means compliance was not just about the idea, but also about adhering to NASA's specified proposal structure, mission constraints, cost caps or accounting rules where applicable, schedule and phase expectations, and any restrictions specific to Missions of Opportunity.
NASA also noted that this solicitation was released alongside two related opportunities: the Astrophysics Explorer 2014 Small Explorer AO (NNH14ZDA013O) and a separate call for U.S. Participating Investigators (APEX USPI) through ROSES-14 (NNH14ZDA001N). This matters because it signals that NASA was coordinating multiple Explorer-related pathways at the same time: one for full mission concepts (including Missions of Opportunity), one for Small Explorers, and one for U.S. investigators to participate in certain missions, creating multiple entry points depending on team size, mission maturity, and role.
For questions, NASA directed proposers to contact Dr. Wilton T. Sanders, the Astrophysics Explorers Program Scientist at NASA Headquarters, via email (wilton.t.sanders@nasa.gov) with the subject line "Explorer MO PEA," and provided phone and fax numbers. NASA stated that responses would be emailed and also posted publicly to the FAQ section of the Explorers acquisition website, while preserving the anonymity of individuals and institutions submitting questions. Finally, the notice clarified that the solicitation constituted a NASA Research Announcement under FAR 6.102(d)(2), framing it as a competitive research-based selection rather than a traditional procurement for a defined deliverable.
