PSLV-XL to Launch Proba-3 Mission: An Introduction to ISRO’s Workhorse. Proba-3 mission is expected to be launched by the Indian Space Research Organisation (ISRO) on a record-breaking successful Polar Satellite Launch Vehicle (PSLV) in its XL configuration. This is yet another milestone for ISRO, which has emerged to be a leader in cost-effective, efficient satellite launches. A deep dive into the mission and the role of PSLV in this exciting endeavor.
What is the Proba-3 Mission?
Proba-3 is a European Space Agency (ESA) mission to conduct tests and demonstrations of the advanced technologies needed for precise formation flying. However, it consists of two spacecraft that fly in a precise formation, flowing apart by 150 meters. The aim of this is to generate an artificial solar eclipse so that we can examine the corona of the Sun in previously unexplored detail.
Key Objectives of Proba-3:
- Performance of autonomous formation flying.
- To perform high-accuracy coronagraphy to observe the Sun’s outer atmosphere.
- New navigation, control, and propulsion systems for future missions.
PSLV-XL: ISRO’s Trusted Workhorse
The PSLV-XL variant of the PSLV specifically launches with heavier payloads and meets special mission requirements. PSLV has been ISRO’s workhorse since its days for the launch of satellites in different orbits, including Sun-synchronous, geostationary, or polar orbits.
Features of the PSLV-XL Variant:
- Enhanced Boosters: In addition, six extended solid rocket strap-ons add payload to the thrust.
- Payload Capacity: Capable of delivering payloads of up to 1,800 kg to Sun-synchronous orbit.
- Track Record: Over 50 successful launches with a 94% success rate.
- Flexibility: It is well suited to deploying multiple satellites within a single mission.
PSLV-XL variant has previously flown Chandrayaan-1 and Mars Orbiter Mission (Mangalyaan), and has established itself as a ready option for carrying out complex international payloads like Proba-3.
ISRO’s increasing equivalent with ESA
ISRO’s expanding collaboration with international space agencies is signified in Proba-3. ISRO`s partnership with ESA is strengthened by launching this mission and ISRO demonstrates its capacity to handle technology and precision-based missions.
Why PSLV for Proba-3?
- Proven Success: Consistently achieving high precision delivering satellites to orbit.
- Cost-Effectiveness: To fulfill affordable launch services without compromising reliability.
- Advanced Capabilities: Proba-3’s formation flying mission is the motivation for a configuration such as the XL.
What Makes This Mission Useful for Space Research?
The results from Proba-3 will guide future formation flying missions, needed for so many applications, from Earth observation to astronomy to actual interplanetary exploration. In addition, the coronagraphy experiments associated with the mission will enhance understanding of solar activity, with real importance for research of solar storms and space weather.

ISRO and PSLV Take a Leap Forward
Proba-3 mission also once again shows that PSLV is a globally counted on launch vehicle, and brings forth the capability of ISRO to work with complex international missions. By facing such issues, ISRO not only makes progress in technical terms but also raises the stature of India in the world space industry.
The PSLV-XL is back as the Proba-3 mission is preparing for launch, with all eyes on ISRO to deliver another stellar result. This is not just a precision and an innovative mission, but also a truly global partnership in dissecting the mysteries of the universe.
