Axon' Cable destination moon

25 Aug 2023

“'I reached my destination and you too!’”, Chandrayaan-3, the Indian space probe has successfully soft-landed on the moon. The mission developed by the Indian Space Research Organisation (ISRO) includes a lunar orbiter, a lander and a rover. After soft-landing on the southern Pole of the moon, the objective will be to conduct in-situ scientific experiment to help lunar expeditions reaching new heights. Axon’ Cable is taking part to the adventure by providing wires and data transmission cable assemblies to the mission.

Data transmission

Axon’ Cable equips the Indian mission Chandrayaan-3 with MIL-STD-1553 data bus harnesses. Their role is essential as they transfer data to the electronic devices of the different subsystems of the space probe. This includes data related to telemetry, command and control, sensor readings and actuator commands. These reliable transmission networks offer high security of data, signal integrity, weight and space saving.

A hostile environment

Considering the unique and extreme geographical and environmental conditions of the moon, landing on the South pole is a real challenge, making life difficult for the interconnect solutions carried. Extreme temperature variations, mechanical stress due to a delicate landing, restricted access to sunlight and electrical power, need for extreme reliability and space saving, these critical requirements are met by Axon’ interconnect solutions.

Long-time collaboration for Axon’

In the past, ISRO's launcher has already carried large-scale missions for which Axon' has provided solutions such as Chandrayaan-1 and Mangalyaan.  For Chandrayaan-1, Axon' provided ESA wires and data transmission harnesses integrated with the lunar orbiter. For the mars mission Mangalyaan, Axon’ delivered the cabling system (cables, couplers and splices) for transmitting data between the probe's electronic equipment to ISRO.
