Astrolab Unveils Solar-Powered Lunar Power Node
The LUMIS system is designed to supply energy and connectivity to equipment operating near the lunar south pole.
Updated on Nov. 6, 2026 in Space
Astrolab has introduced the Lunar Utility Module for Industrial Services (LUMIS), a solar-powered node designed to supply energy, wireless connectivity, and data processing to lunar surface equipment. The company plans to deploy its first LUMIS node in 2028 aboard a SpaceX Starship mission.
Why it matters
Power and communications are among the main constraints on sustained operations at the lunar south pole, where terrain and long periods of darkness complicate missions. A modular node that can be moved across the surface could make such operations more practical.
Each initial LUMIS demonstration node is designed to generate 2 kW of electrical power and operate for more than 400 hours on internal energy reserves, with Astrolab projecting 20 kW per node in future versions. These are company design targets, and the system has not yet flown.
The players
Astrolab
Astrolab is a company developing lunar surface systems, including the FLEX rover and the newly introduced LUMIS node and LUNAR OS software platform.
SpaceX
SpaceX is the private aerospace company whose Starship vehicle is planned to carry the first LUMIS node to the Moon.
The details
LUMIS combines a vertical solar array, batteries, communications transceivers, and onboard computing hardware to provide wireless power transfer and local Wi-Fi and 5G connectivity. Astrolab's FLEX rover can transport the nodes, allowing them to be positioned where sunlight exposure and communications coverage are more favorable.
Timeline
2028: Planned first LUMIS node deployment on a commercial FLEX mission aboard SpaceX's Starship.
The Big Picture
Sustained south-pole operations under NASA's Artemis program depend on reliable power and communications that current surface infrastructure has not yet provided at scale. Astrolab's LUMIS proposal is a commercial attempt to fill that gap with movable, solar-powered nodes.
If the LUMIS design performs as described, it could eventually provide power and connectivity for lunar equipment, with interconnected installations potentially reaching 100 kW. Near-term effects are limited, since the first node is not scheduled to fly until 2028.
The takeaway
Reliable power and communications are prerequisites for operations at the lunar south pole, and LUMIS represents one commercial approach to supplying them. Its progress will depend on whether the 2028 demonstration performs as designed.
What happens next
Astrolab plans to deploy its first LUMIS node in 2028 on a commercial FLEX mission aboard SpaceX's Starship.
