## Why It Matters
Umbra 05 represents a concrete example of a modern, compact synthetic aperture radar satellite fielded by a private operator. As part of the Umbra-SAR program, it extends Umbra’s constellation of SAR spacecraft, contributing an additional platform to the program’s overall capabilities and operational cadence. Its small 65 kg launch mass exemplifies the trend toward lighter, more cost-effective SAR satellites that can be launched on commercially available rockets such as the Falcon 9 Block 5. The mission’s integration into a sequential program (following Umbra 04 and preceding Umbra 06) indicates incremental deployment of assets rather than a single large spacecraft, which can improve redundancy and revisit rates for a constellation. Official identifiers (SCN 55036, COSPAR 2023-001AD, NSSDCA 2023001AD) and the recorded launch profile provide traceable catalogue data used by satellite operators, cataloguers, and researchers tracking the growth of SAR satellite deployments.

## Notable For
- Small launch mass for a SAR satellite: 65 kg launch weight.  
- Launched on a Falcon 9 Block 5 vehicle (booster/flight qualifier B1060.15) from Cape Canaveral SLC-40.  
- Formal catalog identifiers: SCN 55036, COSPAR 2023-001AD, NSSDCA 2023001AD.  
- Part of the Umbra-SAR program sequence, positioned between Umbra 04 and Umbra 06.  
- Manufactured and operated by Umbra (private operator/manufacturer).
