Correct answer
Polar Satellite Launch Vehicle
Why this answer is correct
The correct answer is Polar Satellite Launch Vehicle.
Key Points
- Polar Satellite Launch Vehicle (PSLV) is an expendable launch vehicle developed and operated by the Indian Space Research Organisation (ISRO).
- It was first launched on 20 September 1993 and has since become one of the most reliable launch vehicles in the world.
- PSLV is designed to place satellites into polar orbits, which are used extensively for applications like earth observation, remote sensing, and disaster management.
- The vehicle is capable of delivering payloads to low Earth orbit (LEO), geostationary orbit (GEO), and sun-synchronous orbit (SSO), making it a versatile option for launching satellites.
- PSLV earned the nickname "Workhorse of ISRO" because of its consistent performance, completing over 50 successful missions as of recent years.
Additional Information
- Key Features of PSLV:
- PSLV uses a four-stage configuration with alternating solid and liquid propulsion systems, ensuring flexibility and high precision during launches.
- The payload capacity of PSLV varies depending on the configuration, with a maximum capacity of around 1,750 kg to sun-synchronous orbit.
- It can carry multiple satellites in a single launch, demonstrating its ability to cater to global satellite deployment needs.
- Notable missions include the launch of 104 satellites in a single mission (PSLV-C37) in 2017, a world record for satellite launches in one go.
- Applications of PSLV:
- PSLV has been used to launch satellites for purposes such as earth observation, navigation, communication, scientific exploration, and interplanetary missions.
- It played a key role in launching India's prominent missions like Chandrayaan-1 (2008), Mars Orbiter Mission (Mangalyaan) in 2013, and the RISAT series of satellites for radar imaging.
- PSLV is also used for commercial satellite launches globally, making India a significant player in the international space launch market.
- ISRO Overview:
- The Indian Space Research Organisation (ISRO) is India's national space agency, headquartered in Bengaluru, Karnataka.
- ISRO is known for its cost-effective and efficient space missions, cementing India's position in the global space industry.
- PSLV is one of ISRO’s most successful projects, contributing to India's reputation as a reliable satellite launch provider.
- Other Indian Launch Vehicles:
- ISRO operates other launch vehicles such as the Geosynchronous Satellite Launch Vehicle (GSLV) and GSLV Mk III, which are designed for heavier payloads and higher orbits.
- Small Satellite Launch Vehicle (SSLV) is ISRO's newest development, aimed at launching small payloads at lower costs.
Important Points
- Global Recognition: PSLV's reliability and cost-effectiveness have attracted several countries to use its services for satellite launches.
- Historical Achievements: PSLV contributed to India's first interplanetary mission, Mangalyaan, which successfully reached Mars in 2014.
- Versatility: PSLV’s capability to launch satellites into different orbits makes it suitable for diverse missions, including scientific research and disaster monitoring.
- Future Plans: ISRO continues to enhance PSLV’s capabilities, integrating advanced technologies to ensure greater precision and efficiency.
