## Summary  
Delta 0100 is an American expendable launch system, part of the Delta family of rockets. It was used to deploy payloads such as meteorological and Earth-observation satellites into orbit. The system includes variants like the Delta 0300 and Delta 0900, distinguished by their configurations.

## Key Facts  
- **Type**: Expendable launch vehicle (instance of `launch vehicle`).  
- **Parent Class**: Part of the Delta family of rockets (`Delta [class]`).  
- **Country of Origin**: United States.  
- **Key Components**: Includes `Long Tank Thor` as the first stage, `Delta F` as the second stage, and `Castor 2` solid rocket boosters (3 or 9 depending on configuration).  
- **Notable Payloads**: Launched satellites like `Nimbus 5`, `Landsat 1`, `AMSAT-OSCAR 6`, `NOAA-2`, `NOAA-3`, and `ITOS-E`.  
- **Aliases**: Also known as Delta 100, Delta 0300, Delta 300, Delta 0900, Delta 900, and デルタ0100.

## FAQs  
### Q: What satellites did Delta 0100 launch?  
A: Delta 0100 launched several significant payloads, including the `Nimbus 5` meteorological satellite and `Landsat 1`, the first satellite of the U.S. Landsat program.  

### Q: What are the main components of Delta 0100?  
A: The launch system includes the `Long Tank Thor` first stage, `Delta F` second stage, and `Castor 2` solid rocket boosters (with 3 or 9 units depending on the variant).  

### Q: Is Delta 0100 still in use?  
A: No, Delta 0100 is an expendable launch system and is no longer active.  

## Why It Matters  
Delta 0100 played a critical role in the early era of space exploration and satellite deployment. As part of the Delta rocket family, it contributed to advancements in meteorology, Earth observation, and communications by launching key payloads like `Landsat 1`, which pioneered remote sensing technology. Its versatility in configurations (e.g., Delta 0300 and Delta 0900) demonstrated the adaptability of expendable launch systems for varying mission requirements. Though retired, its legacy persists in modern Delta rockets and the broader evolution of launch vehicle technology.  

## Notable For  
- **Versatility**: Offered multiple configurations (e.g., Delta 0300, Delta 0900) to accommodate different payload needs.  
- **Historic Payloads**: Launched pioneering satellites like `Landsat 1`, the first of its kind in the U.S. Landsat program.  
- **Component Innovation**: Utilized the `Castor 2` solid rocket boosters, which were adjustable in number (3 or 9) for mission-specific thrust requirements.  

## Body  
### Variants and Configurations  
- Delta 0100 includes subvariants like Delta 0300 and Delta 0900, differing primarily in the number of `Castor 2` boosters (3 vs. 9).  

### Key Launches  
- Deployed `Nimbus 5` (1972), a U.S. meteorological satellite.  
- Launched `Landsat 1` (1972), the first satellite in the Landsat program.  
- Carried amateur radio satellite `AMSAT-OSCAR 6` and weather satellites `NOAA-2`, `NOAA-3`, and `ITOS-E`.  

### Technical Specifications  
- **First Stage**: `Long Tank Thor`.  
- **Second Stage**: `Delta F`.  
- **Boosters**: `Castor 2` (3 or 9 units).
