NASA’s upper-stage SLS exploration passes critical design review

The Exploration Upper Stage (EUS) for future flights of NASAThe Space Launch System rocket has passed Critical Design Review, or CDR.

A panel of experts evaluated the EUS in the latest review to determine that the stage design meets the requirements for future missions. This most recent assessment certifies that EUS meets critical design requirements to withstand deep space environments and will ensure the safety of astronauts when completed. The review committee also assessed the testing processes, the ability of the industrial base to supply parts and tools, and production plans. Boeing, the main contractor for the EUS and the main stage, will manufacture and assemble the upper stage at NASA’s Michoud Assembly Facility in New Orleans.

A stage structural test item will be tested at NASA’s Marshall Space Flight Center in Huntsville, Alabama, where the SLS The program is managed. The flight item will undergo Green Run testing at the agency’s Stennis Space Center near Bay St. Louis, Mississippi, prior to its first flight, similar to the SLS main stage Green Run tests currently underway, including a hot combustion of the engines.

NASA’s Space Launch System (SLS) rocket provides multi-stage propulsion to send NASA’s Orion spacecraft and heavy payload to the moon for the Artemis moon missions.

Upon takeoff, the main stage and dual solid rocket thruster fire to propel the rocket off the launch pad and send it into orbit. Once in orbit, the upper stage provides propulsion in space to set the spacecraft on a precise trajectory.

While the rocket’s main stage design will remain the same for each of the Artemis missions, the rocket’s upper stage is selected to meet the various mission requirements and objectives.

For the first three Artemis missions, including the mission that will take the first woman and next man to the moon by 2024, SLS will use a provisional cryogenic propulsion stage with an RL10 engine to send Orion to the moon. Subsequent missions with the evolved configuration of the SLS Block 1B rocket will use an upper stage of exploration with larger fuel tanks and four RL10 engines to send a manned, large cargo Orion to the Moon.

NASA’s space launch system will be the most powerful rocket they have ever built. Once completed, SLS will allow astronauts to begin their journey to explore distant destinations in the solar system.

NASA’s Space Launch System, or SLS, is a super-heavy-duty launch vehicle that provides the foundation for human exploration beyond Earth’s orbit. With its unprecedented power and capability, the SLS is the only rocket capable of sending Orion, astronauts and cargo to the Moon in a single mission.

Offering more payload mass, volume capacity and energy, the SLS is designed to be flexible and evolutionary and will open up new possibilities for payloads, including robotic science missions to places like the Moon, Mars, Saturn, is Jupiter.

The SLS team is producing NASA’s first space rocket built for human space travel since the Saturn V. Engineers are making progress towards delivering the first SLS rocket to NASA’s Kennedy Space Center in Florida for its first launch on the Artemis I moon mission

NASA is working to land the first woman and next man on the Moon by 2024. SLS and Orion, along with the Human Landing System and Gateway orbiting the Moon, are NASA’s backbone for exploration of the Moon. deep space.
