Structural evolution of the TeamIndus spacecraft that will land on the Moon

How the lander design evolved for structural integrity and robustness

First structural design of the spacecraft with main components labelled.
Aluminum foam used in the landing gear.

Landing gear absorption material

1: Crushable honeycomb structure in the landing gear allows the spacecraft to better absorb the impact forces on landing. 2: Honeycomb-structure top view pre-impact (left) and crushed post-impact (right).
  1. Better absorption of impact forces meant that the landing gear height was reduced, saving more cost.
  2. Crushable honeycomb structure is lighter than the aluminum foam because it has a hollow structure.

Lander decks

The Landing

Landing gear footpad can change angle based on the terrain below it.
Our final landing gear with a crushable honeycomb structure in both the primary and secondary legs to absorb maximum impact forces during the landing.
