Project Celestial: Multi-Domain Site Selection Framework for Terrestrial and Maritime Spaceport Infrastructure

**Changes to Q&A:** Q1 received a new answer clarifying that open-source information gathering from the global internet is acceptable (previously unanswered). All other questions and answers remain unchanged.

One new Q&A added: Q1 asks whether solutions can pull real-time data from the global internet or must operate as a standalone air-gapped system. No answer provided yet. Original three questions retained with unchanged answers regarding API/data standards, equal weighting of terrestrial/maritime domains, and FLDCOM Logistics Planners as primary end-users.

**Summary of Q&A Changes:** The Q1 about anticipated Phase I award numbers was removed. The remaining three sub-questions (on data standards/APIs, terrestrial vs. maritime prioritization, and end-user identification) were consolidated into a single Q1 with identical answers, maintaining the previous guidance that both domains should be treated equally and identifying FLDCOM Logistics Planners as primary end-users.

**New Q&A Added:** Q1 asking about the number of Phase I awards DAF anticipates awarding under Project Celestial. No answer provided yet. **Existing Q&As Renumbered:** Previous Q1 (three-part question on data standards/integration, terrestrial vs. maritime prioritization, and end-user identification) is now Q2 with the same answers unchanged.

Status changed from Pre-Release to Open

**Q&A Updates Summary:** All three existing questions received answers: 1. **Integration requirements:** No mandatory native integration with specific DoD/USSF environments (Platform One, C2 frameworks) required at Phase I. 2. **Terrestrial vs. maritime weighting:** Both domains should be treated equally in Phase I design logic. 3. **End-user clarification:** Primary stakeholder is USSF Space Systems Command, Directorate of Installations, Logistics and Product Support; day-to-day end-users are FLDCOM Logistics Planners (not tactical planners or combatant commanders).

# Summary Three technical clarification questions regarding Project Celestial Phase I: integration requirements with DoD/USSF platforms and data standards; prioritization between maritime versus terrestrial spaceport operations; and identification of primary end-users among listed stakeholders. **Character count: 213**
