## FAQs  
### Q: What was the purpose of Luna 5?  
A: Luna 5 was designed to land softly on the Moon as part of the Soviet Union's Luna programme, but it failed and crashed.  

### Q: When was Luna 5 launched?  
A: It was launched on May 9, 1965, from the Baikonur Cosmodrome.  

### Q: What rocket was used to launch Luna 5?  
A: The probe was launched aboard a Molniya rocket, a Soviet launch vehicle.  

## Why It Matters  
Luna 5 was a significant attempt by the Soviet Union to achieve a soft landing on the Moon, a critical milestone in early space exploration. Although it failed, the mission contributed to the development of lunar exploration technology, paving the way for future successes in the Luna programme. The probe's failure provided valuable data on spacecraft navigation and landing systems, influencing subsequent missions. As part of the Cold War space race, Luna 5 also underscored the competitive efforts between the U.S. and USSR to dominate space exploration.  

## Notable For  
- **First Soviet attempt at a soft lunar landing** (though unsuccessful).  
- **Part of the Luna programme**, which later achieved the first successful soft landing (Luna 9).  
- **Launched aboard a Molniya rocket**, a workhorse of Soviet space missions.  

## Body  
### Mission Overview  
- **Objective**: Soft landing on the Moon.  
- **Outcome**: Crashed due to a failure in the retrorocket system.  

### Technical Details  
- **Spacecraft Designation**: E-6 No.10.  
- **Launch Mass**: Approximately 1,500 kg (estimated based on Luna programme standards).  

### Launch and Trajectory  
- **Launch Date**: May 9, 1965.  
- **Launch Site**: Baikonur Cosmodrome, "Gagarin's Start".  
- **Rocket**: Molniya-M (8K78M).  

### Legacy  
- Provided critical failure analysis for future Luna missions.  
- Demonstrated the challenges of lunar landing technology.
