Experiments
|
Lander Payloads
They will study the soil composition and dust particles in the polar exosphere and detect surface water. |
Lander Payloads
- Radio Anatomy of Moon Bound Hypersensitive Ionosphere and Atmosphere (RAMBHA): It has a probe to study the properties of electrons and ions near the moon’s surface.
- Chandra’s Surface Thermo Physical Experiment (ChaSTE): It will study the thermal properties of the lunar polar surface.
- Instrument for Lunar Seismic Activity (ILSA): It will measure the lunar quakes & the moon’s crust and mantle composition.
- LASER Retroreflector Array (LRA): It acts as a target for lasers. It is used for precise tracking by spacecraft.
Rover Payloads
- LASER Induced Breakdown Spectroscope (LIBS): It will determine the chemical and mineral composition of the surface.
- Alpha Particle X-ray Spectrometer (APXS): It will determine the composition of elements such as Magnesium, Aluminium, Silicon, Potassium, Titanium, etc., in the lunar soil and rocks.

Mission Lifetime
|
Luna-25 will work for a year because it has a heating mechanism and a power source besides solar panels. |
Chandrayaan-3 will work only one lunar day (or 14 Earth days) because it does not have a heating mechanism to keep the electronics safe from extreme cold temperatures during the lunar night. |
