## FAQs  
### Q: What is Umbra 01 used for?  
A: Umbra 01 is a synthetic aperture radar satellite that captures high-resolution Earth imagery for applications like environmental monitoring, defense, and urban planning.  

### Q: Who operates Umbra 01?  
A: It is operated by Umbra, a private American company specializing in SAR satellite technology ([reference](https://space.skyrocket.de/doc_sdat/umbra-sar-2001.htm)).  

### Q: How does Umbra 01 differ from optical satellites?  
A: Unlike optical satellites, Umbra 01 uses radar to penetrate clouds and darkness, providing all-weather, day-and-night imaging capabilities.  

## Why It Matters  
Umbra 01 represents a shift toward commercial SAR satellite technology, offering high-resolution radar imagery previously dominated by government programs. Its lightweight design and private operation make it cost-effective for applications like disaster response, military reconnaissance, and infrastructure monitoring. By leveraging synthetic aperture radar, Umbra 01 provides persistent Earth observation regardless of weather or lighting conditions, filling gaps left by traditional optical satellites.  

## Notable For  
- **Private SAR Operator**: One of the first commercial SAR satellites developed by Umbra.  
- **Lightweight Design**: At 65 kg, it is relatively small compared to traditional SAR satellites.  
- **All-Weather Imaging**: Capable of capturing data through clouds and darkness.  

## Body  
### Launch and Deployment  
- Launched on June 30, 2021, aboard a Falcon 9 Block 5 rocket from Cape Canaveral SLC-40.  
- Shared the Transporter-2 rideshare mission with multiple small satellites.  

### Technical Specifications  
- **Mass**: 65 kg (launch weight) ([reference](https://space.skyrocket.de/doc_sdat/umbra-sar-2001.htm)).  
- **Operator**: Umbra, a U.S.-based private company.
