- Designed specifically for launching small satellites at a lower cost compared to larger rockets
- Successfully launched on its first mission on August 7, 2022 (SSLV-D1), carrying multiple satellites including EOS-07 and EOS-08
- Can place payloads into both low Earth orbit and Sun-synchronous orbit, providing flexibility for different satellite applications
- Represents a significant step in India's space program for making space access more affordable and accessible

## Body
### Technical Specifications
The Small Satellite Launch Vehicle (SSLV) is designed as a small-lift launch vehicle with specific technical characteristics:
- **Mass**: Approximately 116 tonnes
- **Height**: 34 metres
- **Diameter**: 2.0 metres
- **Payload capacity**: 500 kg to low Earth orbit or 300 kg to Sun-synchronous orbit
- **Country of origin**: India

### Design and Development
The SSLV was designed by the Vikram Sarabhai Space Centre and manufactured by the Indian Space Research Organisation (ISRO). It represents a dedicated launch vehicle for small satellites, addressing the growing demand for affordable access to space. The development of the SSLV was part of India's strategy to provide cost-effective launch solutions for small and microsatellites.

### Mission History
The first flight of the SSLV occurred on August 7, 2022, as the SSLV-D1 mission. This mission successfully placed multiple satellites into orbit, including the Indian Earth observation satellites EOS-07 and EOS-08. The SSLV has demonstrated its capability to launch small payloads efficiently and at a lower cost compared to larger launch vehicles.

### Operational Capabilities
The SSLV is designed to launch payloads into two primary orbital configurations:
- **Low Earth Orbit (LEO)**: Up to 500 kg capacity
- **Sun-synchronous orbit**: Up to 300 kg capacity

This dual capability makes the SSLV suitable for a wide range of applications, from Earth observation to scientific research and educational missions.

### Impact on Space Industry
The SSLV has significantly impacted India's space program by:
- Reducing launch costs for small satellites
- Increasing launch frequency and flexibility
- Enabling more frequent deployment of small satellites for various applications
- Providing a competitive alternative to larger, more expensive launch vehicles

### Related Missions and Satellites
The SSLV has been used to launch several Indian satellites, including:
- **EOS-07 and EOS-08**: Earth observation satellites
- **AzaadiSAT**: Indian student nanosatellite (though this mission experienced a failure)
- **Janus-1**: Artificial satellite

These missions demonstrate the SSLV's role in supporting India's space exploration and satellite deployment programs.
