Argonaut or European Large Logistics Lander (EL3) is a class of lunar landers designed by the European Space Agency in partnership with Airbus to deliver payloads to the surface of the Moon.[1] The lander is being designed with a versatile set of uses in mind, including use as a power station, support for a rover, cargo delivery, and infrastructure delivery. It is envisioned to launch on an Ariane 64 launch vehicle.[2] [3] [4] As of July 2024, Argonaut Mission 1 is expected to be launched in 2031.[5]
In 2022, ESA formally sought funding for the lander in their ministerial meeting.[6] In 2024, Redwire Space was awarded a contract by ESA to develop a robotic arm for use on the lander.[7]
The Argonaut lander will consist of the descent element, cargo platform and payload. Capable of delivering upto 2100 kg, the craft will reportedly be able to land with an accuracy of 50–100 meters.[8] Engine testing began in 2024.[9] Also in 2024, the ESA committed to an Argonaut mission in 2031.[10]
