NASA Fires Up a Massive Solar Engine to Support Moon Missions

NASA has activated a powerful solar electric propulsion system that will serve as the driving force behind its upcoming lunar space station. Known as the Power and Propulsion Element, the spacecraft will supply energy and mobility for Gateway, a key part of NASA’s lunar exploration plans. This NASA solar engine will help push future missions deeper into space, supporting the agency’s broader goals under the Artemis program.

The system successfully powered on in early 2023, marking a critical step in its development. Engineers confirmed that the spacecraft can generate up to 60 kilowatts of electricity.

That capacity is enough to support high-speed communications, power essential systems, and control the spacecraft’s orientation and orbital path. According to NASA, this milestone proved the system’s readiness to perform in the demanding conditions of lunar orbit.

NASA’s solar engine takes shape in California

NASA’s Glenn Research Center in Cleveland is overseeing the development. Construction is currently taking place at Lanteris Space Systems in Palo Alto, California. Teams at the site have secured the main electrical system and enclosed it within protective outer panels to shield sensitive components.

Next on the schedule is the integration of the propulsion hardware. This includes three advanced thrusters, each producing 12 kilowatts of power, built by L3Harris. Engineers will also install four BHT-6000 thrusters, each rated at 6 kilowatts, manufactured by Busek.

In parallel, the rollout solar arrays that will power Gateway have been completed and are undergoing testing at Redwire’s facility in Goleta, California.

Gateway to support Artemis and deep space goals

Gateway, NASA’s planned lunar space station, will orbit the Moon in a stable, highly elliptical path. It is designed to support astronauts during short-duration visits, acting as a staging point for missions to the Moon and beyond. The outpost will provide living quarters, host scientific research, and allow for testing of new space technologies.

Unlike the International Space Station, Gateway will not be continuously occupied. Instead, it will host rotating crews who will carry out experiments and prepare for future exploration.

NASA officials say Gateway will play a central role in returning humans to the Moon and preparing for future missions to Mars. By operating farther from Earth, the outpost will help researchers understand how both spacecraft and astronauts perform in deep space.
