Video shows engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, completing the welds to form the launch vehicle stage adapter (LVSA) for NASA’s Space Launch System (SLS) rocket. The launch vehicle stage adapter in this video will fly on Artemis II, the first crewed mission of NASA’s Artemis program. Upon stacking the upper and lower cones, technicians use advanced robotic tooling and an innovative process called friction stir welding, to join the cones of the LVSA to form one structure.

The next step in the manufacturing process is the installation of the pneumatically actuated frangible joint which sits atop the LVSA and helps separate the core stage and LVSA from the Interim Cryogenic Propulsion Stage (ICPS) during flight. After the core stage launches the rocket, the ICPS provides the power to send the Orion spacecraft and its crew to the Moon.

Before Artemis astronauts land on the Moon in 2024, robots will scout the surface for resources and collect information about the lunar South Pole. Some landers and rovers will come equipped with handy tools, including drills and chemical analyzers, to examine what lies below the lunar surface.

The Polar Resources Ice Mining Experiment-1 (PRIME-1) will be the first in-situ resource utilization demonstration on the Moon. Additionally, for the first time, NASA will robotically sample and analyze for ice from below the surface.

While NASA is working aggressively to meet our near-term goal of landing the first woman and next man on the Moon by 2024, our Artemis program also is focused on taking steps that will establish a safe and sustainable lunar exploration architecture. NASA is taking a critical step forward by releasing a solicitation for commercial companies to provide proposals for the collection of space resources.

To meet NASA’s requirements, a company will collect a small amount of Moon “dirt” or rocks from any location on the lunar surface, provide imagery to NASA of the collection and the collected material, along with data that identifies the collection location, and conduct an “in-place” transfer of ownership of the lunar regolith or rocks to NASA. After ownership transfer, the collected material becomes the sole property of NASA for our use.

NASA’s goal is that the retrieval and transfer of ownership will be completed before 2024. The solicitation creates a full and open competition, not limited to U.S. companies, and the agency may make one or more awards. The agency will determine retrieval methods for the transferred lunar regolith at a later date.

Over the next decade, the Artemis program will lay the foundation for a sustained long-term presence on the lunar surface and use the Moon to validate deep space systems and operations before embarking on the much farther voyage to Mars. The ability to conduct in-situ resources utilization (ISRU) will be incredibly important on Mars, which is why we must develop techniques and gain experience with ISRU on the surface of the Moon.

Preparing to explore the surface of the Moon goes well beyond designing and building safe spacecraft and spacesuits. NASA also has to ensure the surface vehicles and suits have the mobility required to do science, and that astronauts have the tools they need to identify and scoop up rock and soil samples. Additionally, NASA astronauts are trained in geology, spending countless hours practicing doing science at locations on Earth that resemble regions they might see on the Moon. All this is done in an effort to establish a long-term presence on the Moon and to help answer some outstanding science questions about the history of Earth and of the solar system.

Blue Origin dicit:

The Blue Origin National Team, which includes Lockheed Martin, Northrop Grumman, and Draper, was selected by NASA to begin to develop the Artemis Human Landing System.

Using existing and in development technologies provides the head start needed to meet NASA’s goal of landing at the South Pole of the Moon. Lockheed Martin’s Ascent Element is based on Orion; Northrop Grumman’s Transfer Element is based on Cygnus; and Blue Origin’s Descent Element is based on the Blue Moon lander and BE-7 engine, which has been in development for several years.

Engineers at Northrop Grumman’s facility in Elkton, Maryland successfully conducted the third and final test of the attitude control motor (ACM) that provides steering for the Launch Abort System (LAS) on NASA’s Orion spacecraft, qualifying the motor for Artemis II, Orion’s first mission with astronauts. The LAS, consisting of three solid rocket motors, is designed to carry crew to safety in the event of an emergency during launch or ascent atop the agency’s Space Launch System rocket.

During the 30-second test, eight high pressure valves directed more than 7,000 pounds of thrust in multiple directions while firing at freezing conditions. All three motors on the LAS will be qualified for crewed flights ahead of Artemis II, another step that brings NASA closer to sending the first woman and next man to the Moon by 2024.
