Partnership Opportunity Document (POD) For NASA Goddard Space Flight Center (GSFC) Small Explorer (SMEX) Spacecraft and Telescope Assembly for expected 2024 NASA Astrophysics Small Explorer Announcement of Opportunity July 2024 1.0 Introduction and Scope Current planning calls for NASA's Science Mission Directorate (SMD) to release an Astrophysics Small Explorer (SMEX) Announcement of Opportunity (AO) in the spring of 2025 to solicit proposals to accomplish science objectives from the 2020 Decadal Survey. In partnership with the Principal Investigator (PI)-led team, NASA Goddard Space Flight Center (GSFC) is developing a mission concept to be proposed for the upcoming SMEX AO. The mission will use a single instrument with a telescope mounted to a spacecraft bus. The observatory will be launched into a 600-700km sun-synchronous orbit. The mission operations center is currently planned to be at GSFC. This partnership opportunity is being issued to select a teaming partner to serve as the satellite (Spacecraft) integrator for this SMEX mission, and the integrated optical telescope assembly (OTA) subsystem provider for this SMEX mission. Spacecraft and telescope vendors encouraged to establish partners with one another for the purposes of responding to this opportunity. The satellite (Spacecraft) integrator for this SMEX mission, includes providing: a spacecraft bus consistent with a Class D mission per NPR 8705.4 Risk Classification for NASA Payloads instrument to spacecraft integration and environmental testing support (either at the vendor's facility or at GSFC) integration support for the observatory (integrated spacecraft + payload) to launch vehicle, and support for initial mission operations (launch and early orbit operations) and ongoing mission support of the SC Bus. The telescope integrator for this SMEX mission, includes providing: an OTA subsystem meeting the following nominal requirements (additional details described in the detailed data package): 0.75 m aperture 0.62 deg2 field of view Capable of housing the instrument focal plane assembly and two filter wheels in series support for instrument integration and instrument-level environmental testing at GSFC GSFC intends to maintain an essential degree of insight into satellite integration and will exercise essential oversight to ensure that the implementation is responsive to NASA requirements and constraints as defined in the upcoming AO (final release in 2025). NOTE: Upon selection, GSFC may discuss, and further tailor the roles proposed by respondents in the best interests of the proposal. The proposed mission is currently in pre-Phase A. If the proposal is downselected, the next step in the proposal process is a mission concept study culminating in a Concept Study Report (CSR), followed by a Site Visit. The following schedule should be used as a basis for responses to this opportunity: Release of draft AO - Late 2024/Early 2025 Release of final AO - FY2025 2nd quarter (target) Pre-proposal conference ~3 weeks after final AO release Step-1 proposal due 90 days after AO release Selection for competitive Phase A studies - Dec 2025 (estimated) Concept Study Reports (CSRs) due - Oct 2026 (estimated) Site Visit Early 2027 (estimated) Step-2 downselect Mid 2027 (estimated) AO required Launch Readiness Date- TBD based on AO Total cost and cost fidelity are important issues for the proposal. The cost cap for this AO is expected to be ~$175M, excluding launch vehicle, and not including mission specific adjustments to the cap. Proposed mission cost shall include the instrument, spacecraft, instrument to spacecraft integration support, environmental testing, launch site operations, and mission and science operations for a minimum of 3 years. Reserves will be held at the Project level and not with the partner. A Phase A mission concept study for downselected proposals will receive TBD real year dollars (RY$) in funding from NASA SMD. There will be no exchange of funds between the teaming partners for the portion of this partnership opportunity dealing with the preparation of the initial submission (Pre-Phase A, Step 1 proposal). Teaming partners are expected to support mission concept development and proposal development using internal funding. This will include considerable interaction between partners throughout this Pre-Phase-A effort. If downselected for Phase A, partial funding will be available to the teaming partners for Phase A, but company internal funding may still be required to provide support for generation of a CSR and the Site Visit. Full funding will be available for Phase B onward should the candidate mission concept be competitively selected for those additional phases. 2.0 Requirements 2.1 Accommodate GSFC Provided Payload The OTA is expected to accommodate an FPA and filter wheel with the following volume envelopes: Interface Value FPA (cm x cm x cm) - 250 x 250 x 370 Filter Wheel (cm x cm x cm) - TBD x TBD x TBD The spacecraft is expected to accommodate a payload with the following interfaces: Interface Value Volume (cm x cmx cm) - Volumes noted above plus a small electronics box Maximum Expected Mass (kg) - 68 kg Science Operations Power: (W)* - 132 orbit average Mission Data Generation - 200 GB/day * Does not include thermal heater power More detailed information on the GSFC payload will be provided to those responding with a Notice of Interest (NOI). A Notice of Interest (it is intentionally not called a notice of intent) does not obligate an organization to provide a POD response to any mission. 2.2 Support and Enable Required Concept of Operations The spacecraft from the provider shall support and enable the following operating modes: Continuous science observations of selected bright objects ? 70 from the sun. Science operations requires highly stable fine pointing for observations of up to 35 minutes. This mode will operate 95% of the time following commissioning. Engineering mode for maintenance and troubleshooting propulsive momentum management or other maneuvers of the spacecraft is expected to occur during this time. Communications with the ground will involve scheduled S-band communications for command and telemetry and Ka-band communications for science data downlink. More detailed information on mission operations will be provided to those responding with a NOI. 2.3 Accommodate potential mission orbits. The mission is expected to operate in a sun-synchronous dawn-dusk orbit. The orbit altitude is currently an open trade, but is expected to be between 600 km and 700 km. The provider's spacecraft will be required to operate anywhere within this altitude range. Optional Mission Operations Center. The respondent may propose to provide an alternate mission operations center and mission operations control as part of their response. 3.0 Pre-Proposal Support It is expected that the selected POD respondent will provide support using their own resources to help develop the required proposal elements in response to the 2025 Astrophysics SMEX AO in the following areas: Item 1: Spacecraft Bus and associated support This will involve meeting with the PI, project manager, project system engineers, and other proposal team members to establish the mission architecture, to help define both end-to-end mission and elemental performance requirements, to provide well-defined interfaces for the instruments, launch vehicle and ground system elements, and to identify any necessary technology developments, study topics, and/or other risk areas that may affect mission success.
