NASA continues to mark progress in the program to work with business and international partners as part of the Gateway program. The main structure of Halo (residential and logistics outpost) arrives at the Northrop Grumman facility in Gilbert, Arizona, where it will undergo final equipment and verification tests.

Halo will provide Artemis astronauts with space to live, work and conduct scientific research. The residence module will be equipped with the necessary systems including command and control, data processing, energy storage, power distribution and thermal regulation.

After Halo arrived at Thales Alenia Space in Turin, Italy on April 1, NASA and Northrop Grumman held an event on April 24 to recognize the milestone, the module’s significance to Lunar Exploration. The event opened with Northrop Grumman and representatives from Northrop Grumman and NASA, including NASA's associate manager of exploration systems development, Lori Glaze, Gateway program manager Jon Olansen, and NASA astronaut Randy Bresnik. Event attendees, including NASA administrator Todd Ericson, elected officials and senior advisers to local industry and academic leaders, watched Halo and virtual reality demonstrations during the tour.

When the module is located in Arizona, halo engineers and technicians will install propellant lines for fluid transmission, as well as wires for power and data transmission. The radiator will be used in thermal control systems, as well as a rack for life-accommodating them to support hardware, power equipment, flight computers and avionics systems. Several mechanisms will be installed to make the Orion spacecraft, the Moon Landes and the visiting spacecraft dock.

The Moon Link System owned by ESA (European Space Agency) was launched on Halo, which will enable crew and robot systems to communicate between mission control on the moon and on Earth. Once these systems are installed, the component will be tested as an integrated spacecraft and will be tested for thermal vacuum, acoustic, vibration and vibration to ensure the spacecraft is ready to be carried out under harsh conditions in deep space.

Connected with Halo's Northrop Grumman outfit, the power and propulsion element (a powerful solar propulsion system) is being assembled at Maxar Space Systems in Palo Alto, California. Solar propulsion uses the energy collected from solar panels converted to electricity to create xenon ions, which then accelerates them to more than 50,000 miles per hour to create the thrust that pushes the spacecraft.

The central cylinder of the element is similar to a large barrel, is being installed on the propulsion tank and an avionics rack is installed. The first of the three 12-kilowatt thrusters has been delivered to NASA's Cleveland-based Glenn Research Center to be tested later this year before delivering to Maxar and integrating with Power and Prosulsion elements.
