NASA’s SLS upper-end research has undergone a critical review of design


Upper research phase (EUS) for future flights NASAThe Space Launch System rocket has passed its critical design review or CDR.

A panel of experts assessed the EUS in a recent review to determine that the stage design meets the requirements for future missions. This latest assessment confirms that the EUS meets critical design requirements to withstand the deep space environment and when completed will ensure the safety of astronauts. The review committee also assessed the testing processes, the ability of the industrial base to deliver parts and tools, and production plans. Boeing, the main contractor for EUS, as well as the base phase, will manufacture and assemble the top phase at NASA’s Michoud assembly plant in New Orleans.

The article on structural testing of the stage will be tested at NASA’s Marshall Space Flight Center in Huntsville, Alabama, where SLS The program is managed. The flight article will pass Green Run testing at the agency’s space center near St. John’s Bay. Louis, Mississippi, before its first flight, similar to the Green Run testing in the basic phase, which is currently underway, including hot ignition of the engine.

NASA’s Space Launch Rocket (SLS) delivers the propulsion in stages to send NASA’s Orion spacecraft and heavy cargo to the Artemis Lunar Mission Moon.

When lifted, the nucleus and double solid rocket boosters fire the rocket from the launch pad and send it into orbit. Once in orbit, the upper step provides space propulsion to place the spacecraft on a precise orbit.

Although the basic design of the missile will remain the same for each of the Artemis missions, the upper stage of the missile has been selected to meet the different requirements and objectives of the mission.

For the first three Artemis missions, including a mission to land the first woman and the next man on the Moon by 2024, the SLS will use a temporary phase of cryogenic propulsion with a single RL10 engine to send Orion to the Moon. Later missions with a developed SLS Block 1B rocket configuration will use the upper phase of research with larger fuel tanks and four RL10 engines to send Orion crews and large cargo to the Moon.

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

NASA’s space launch system, or SLS, is a super-heavy launch vehicle that provides a foundation for exploring humans outside of Earth’s orbit. With its unprecedented strength and capabilities, the SLS is the only rocket that can send Orion, astronauts and cargo to the Moon in a single mission.

Offering greater payload mass, volume capacity and energy, SLS is designed to be flexible and evolving and will open up new payload opportunities, including robotic science missions to places like the Moon, March,, Saturn, i Jupiter.

The SLS team has been producing NASA’s first deep space rocket designed to travel to space since the time of Saturn V. Engineers are making progress in delivering the first SLS rocket to NASA’s Kennedy Space Center in Florida for the first launch on the Artemis I lunar mission.

NASA is working on landing the first woman and next man on the Moon by 2024. SLS and Orion, along with the human landing system and the Gate in orbit around the moon, are NASA’s backbone for deep space exploration.
