## Summary

This activity requests $13.5M in FY2027, 29% of project 633834, up 5.8% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** Continue: -Engagement with cislunar space community to coordinate test events, collect available data, and drive a whole of government approach to cislunar situational awareness. -AI&T of the satellite system. Complete: -Delivery of the Satellite Bus for system integration and test. -Cislunar data analysis software and cloud-based ground system improving on existing system architectures and leveraging commercial networks for command and control of space vehicle. Commence: - Satellite operations support in preparation for first of a kind cislunar space situational awareness mission.

**FY2026 to FY2027 change.** FY2027 increased compared to FY2026 by $0.743 million due to increased system integration and test activities. FY 2027 funding was realigned from project 63682J to support requirements as described above.

## Before the request year

**FY2026 plans — current year.** Continue: - Procurement of remaining payload and spacecraft materials required to complete Assembly, Integration and Test (AI&T). - AI&T of the satellite system. - Development of cislunar data analysis software and cloud-based ground system improving on existing system architectures and leveraging commercial networks for command and control of space vehicle. - Engagement with cislunar space community to coordinate test events, collect available data, and drive a whole of government approach to cislunar situational awareness. Complete: - Remaining open design work for a cislunar space-based space situational awareness sensor and satellite system.

## Funding

| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 27.3 |
| FY2026 | Enacted | 12.8 |
| FY2027 | Request | 13.5 |

> Prior, current and budget year only — an R-2A activity carries no five-year plan. It sums exactly into its project in the request year and not necessarily in any other.
