## Summary  
Rohini Satellite 1 (RS-1) was the first satellite launched entirely by India, marking a milestone in its space program. Launched on July 18, 1980, it was an Earth observation satellite designed to test India's ability to deploy orbital technology independently. Though it operated for only 47 days, its successful launch demonstrated India's emerging space capabilities.  

## Key Facts  
- **Launch Date**: July 18, 1980.  
- **Country**: India.  
- **Manufacturer**: Indian Space Research Organisation (ISRO).  
- **Launch Vehicle**: Satellite Launch Vehicle (SLV-3), India's first indigenously developed rocket.  
- **Aliases**: RS-1.  
- **Class**: Earth observation satellite.  
- **Launch Site**: Satish Dhawan Space Centre.  
- **Mission Duration**: 47 days (failed due to battery malfunction).  

## FAQs  
### Q: Why is Rohini Satellite 1 significant?  
A: It was the first satellite launched entirely by India, proving ISRO's capability to design, build, and deploy orbital technology without foreign assistance.  

### Q: What rocket launched Rohini Satellite 1?  
A: The Satellite Launch Vehicle (SLV-3), India's first indigenously developed launch vehicle.  

### Q: Was the mission successful?  
A: The launch was successful, but the satellite failed after 47 days due to a battery issue. Despite this, the mission validated India's rocket and satellite technology.  

## Why It Matters  
Rohini Satellite 1 symbolized India's entry into the global space community as a self-reliant player. Its launch demonstrated ISRO's technical prowess in rocketry and satellite engineering, laying the foundation for future missions like the Polar Satellite Launch Vehicle (PSLV) and Mars Orbiter Mission. The project boosted national pride and spurred investment in science and technology, shifting perceptions of India's capabilities from a developing nation to a leader in space exploration.
