Lunar Gateway Will Maintain its Orbit With a 6 kW ion Engine

When NASA sends astronauts back to the Moon as part of the Artemis Program, they will be taking the long view. Rather than being another “footprints and flags” program, the goal is to create a lasting infrastructure that will ensure a “sustained program of lunar exploration.” A major element in this plan is the Lunar Gateway, an orbital habitat that astronauts will use to venture to and from the surface.

The first step in establishing the Gateway is the deployment of two critical modules – the Habitation and Logistics Outpost (HALO) and the Power and Propulsion Element (PPE). According to a recent update, NASA (along with Maxar Technologies and Busek Co.) recently completed a hot-fire test of the PPE propulsion subsystem – the first of many that will ensure that the PPE and HALO will be ready for launch by 2024.

Aerojet Rocketdyne Tests Out its New Advanced Ion Engine System

When it comes to the next generation of space exploration, a number of key technologies are being investigated. In addition to spacecraft and launchers that will be able to send astronauts farther into the Solar System, NASA and other space agencies are also looking into new means of propulsion. Compared to conventional rockets, the goal is to create systems that offer reliable thrust while ensuring fuel-efficiency.
