Exploration Upper Stage facts for kids
The Exploration Upper Stage (EUS) is a powerful part of NASA's new giant rocket, the Space Launch System (SLS). Think of it as the "muscle" that helps push spacecraft even further into space, especially for missions to the Moon and beyond. It's a key piece of the SLS Block 1B version.
What is the Exploration Upper Stage?
The Exploration Upper Stage, or EUS, is like the second big push for the Space Launch System (SLS) rocket. After the main boosters and core stage do their job, the EUS takes over. Its main goal is to give spacecraft, like the Artemis missions heading to the Moon, the extra speed they need to leave Earth's orbit and travel millions of miles into space.
How Does EUS Work?
The EUS is designed to be very powerful. It uses four special engines called RL-10 engines. These engines burn super-cold liquid oxygen and liquid hydrogen as fuel. When they mix and ignite, they create a huge amount of thrust – about 440,000 pounds of force! This incredible power is what helps send heavy spacecraft and supplies on their long journeys.
When Will EUS Fly?
The first time the SLS rocket will fly with the Exploration Upper Stage is planned for 2023. This will be an important step for future space exploration, allowing NASA to send bigger payloads and more complex missions deeper into our solar system.
