The invention provides a star lander storage box propellant management device and a manufacturing method thereof. The star lander storage box propellant management device comprises a supporting cover, a base, a damping management area, an internal net management layer and an external net management layer. The internal net management layer and the external net management layer are welded to the base. The internal net management layer is embedded in and sleeved with the external net management layer. Gas-liquid mixed propellant of the damping management area is drained to the external net management layer, becomes single-phase liquid propellant after being subjected to gas-liquid separation through the external net management layer, and enters an external net management area formed by the external net management layer. The single-phase liquid propellant flows to an internal net management area formed by the internal net management layer through the internal net management layer and is then discharged out of a storage box. Before the external net management layer loses efficacy, the internal net management layer is completely soaked in the propellant, and therefore the constant flowing area of the internal net management layer and low flow resistance generated when liquid passes through a net under large flow are ensured. The internal net management area is completely in the liquid-full state in the drainage process before the internal net management layer loses efficacy, and therefore it is prevented that gas is sucked into a liquid path outlet due to rotational flow when large-flow discharge is conducted, and it is ensured that the air-assistance-free propellant is reliably supplied to an engine.
