Next Generation Launch Vehicle (NGLV)

  • About: The NGLV, developed by ISRO, aims to replace existing launch systems like PSLV, GSLV, and LVM3.
  • It represents a leap in technology and capability for India's space missions.
  • Configuration: It is a three-stage rocket, featuring partial reusability, which enhances cost-effectiveness and efficiency.

Chandrayaan-4

  • Aim: The primary objective is to land on the Moon and return rocks and soils (lunar regolith) to India for analysis.
  • Spacecraft Modules: Consists of 5 modules including a lander, rover, propulsion module, descender module, ascender module, and transfer module.
  • Two Separate Launches: Chandrayaan-4 is the first mission involving 2 launch vehicles to complete a single mission.
  • Launch Vehicles: LVM-3 launches with 3 components (Propulsion Module, Descender Module, Ascender Module).
  • Polar Satellite Launch Vehicle (PSLV) launches the Transfer Module and the Re-entry Module.
