Mission Overview: What Is Chandrayaan‑4?

• Mission Name: Chandrayaan‑4
• Objective: Deploy India’s first modular moon base
• Launch Date (Expected): Late 2026 or early 2027
• Modules Planned: Landing, Surface Habitat, Energy & Communication
• Mission Type: Robotic and possibly crew-supported in the future

Chandrayaan‑4 is not just about landing—it’s about staying. Unlike previous missions, this one aims to assemble structures on the lunar surface, opening the door to long-term lunar exploration.
