How We Make Rockets That Reach the Moon

Join Dr. Roger Billings and the Science Live team as we explore how we make rockets that reach the Moon, featuring NASA’s Artemis II mission — the first crewed return to the Moon in over 50 years!

In this lesson, discover what makes the massive SLS rocket so powerful: its giant solid rocket boosters, liquid hydrogen fuel, and the incredible engineering that lifts millions of pounds into space. You’ll also explore the advanced Orion spacecraft, the groundbreaking laser communication system that beamed HD video from 240,000 miles away, and the record-breaking 252,000-mile journey that took humans farther from Earth than ever before.

Whether you’re a budding space enthusiast, curious about the Artemis program, learning about rocket science, or dreaming of becoming an astronaut, this lesson has something for you. Perfect for students who want to understand the real engineering and technology behind sending rockets — and people — all the way to the Moon and beyond!

All rockets have extra rockets (SRB or Solid Rocket Boosters) to help propel the main rocket to its destination. Thank you Acellus. R51 is so funny I love him. GOD BLESS

    It’s amazing to know that the Artemis 2 went smooth! I’m happy that the astronauts got back safely! It’s also very funny how the biggest problem was their toilet breaking down!

    It’s really cool that there is such a huge difference between solid and liquid fuel. And I gotta say I would buy one of those mars rocks
