NASA's SLS Block 1B to Feature New Payload Adapter for Artemis IV Mission, Enabling Lunar Gateway Construction

NASA's Artemis IV mission will utilize an upgraded Space Launch System (SLS) Block 1B, equipped with a newly developed cone-shaped payload adapter. This adapter, built at NASA's Marshall Space Flight Center, will connect the Orion spacecraft with other payloads, including the Lunar I-Hab, a component of the Gateway lunar space station. The SLS Block 1B can transport 84,000 pounds to the Moon, including both the crewed Orion and a 10-metric ton co-manifested payload. The adapter's design incorporates eight composite panels with an aluminum honeycomb core and two aluminum rings. A flexible assembly approach, using structured light scanning, reduces costs and allows for quick adaptation to various payload sizes. Automated placement robots manufacture lightweight composite panels. Testing of engineering development units has demonstrated the adapter's ability to withstand loads exceeding expectations, ensuring structural integrity for future missions.
