The Indian Space Research Organisation (ISRO) has a robust roadmap for future space exploration after the Chandrayaan-3 mission. Here are the next steps for ISRO:

• Manned mission: ISRO is actively working towards launching its first manned mission, Gaganyaan, by 2022. The mission aims to send a crew of two to low Earth orbit for a limited duration.
• Aditya-L1: ISRO plans to launch Aditya-L1, its first solar mission, to study the Sun's corona and solar storms in 2022. This mission will greatly enhance our understanding of the Sun-Earth connection.
• Venus and Mars missions: ISRO has plans for future missions to explore Venus and Mars. These missions will focus on studying the atmosphere, surface conditions, and searching for signs of life.
• AstroSat-2: ISRO is developing AstroSat-2, a successor to the successful AstroSat mission. This satellite will observe celestial bodies in the X-ray, UV, and visible spectra to unravel the mysteries of the universe.
• Joint missions: ISRO is collaborating with other space agencies for joint missions like the NASA-ISRO Synthetic Aperture Radar (NISAR) mission, which will study Earth's changes and hazards.

These future missions by ISRO demonstrate India's commitment to advancing space exploration and expanding our knowledge of the universe.
