From Earth to the Moon: How Are We Getting There?

image

More than 45 years since humans last set foot on the lunar surface, we’re going back to the Moon and getting ready for Mars. The Artemis program will send the first woman and next man to walk on the surface of the Moon by 2024, establish sustainable lunar exploration and pave the way for future missions deeper into the solar system.


Getting There

Our powerful new rocket, the Space Launch System (SLS), will send astronauts aboard the Orion spacecraft a quarter million miles from Earth to lunar orbit. The spacecraft is designed to support astronauts traveling hundreds of thousands of miles from home, where getting back to Earth takes days rather hours.


Lunar Outpost

Astronauts will dock Orion at our new lunar outpost that will orbit the Moon called the Gateway. This small spaceship will serve as a temporary home and office for astronauts in orbit between missions to the surface of the Moon. It will provide us and our partners access to the entire surface of the Moon, including places we’ve never been before like the lunar South Pole. Even before our first trip to Mars, astronauts will use the Gateway to train for life far away from Earth, and we will use it to practice moving a spaceship in different orbits in deep space.


Expeditions to the Moon

The crew will board a human landing system docked to the Gateway to take expeditions down to the surface of the Moon. We have proposed using a three-stage landing system, with a transfer vehicle to take crew to low-lunar orbit, a descent element to land safely on the surface, and an ascent element to take them back to the Gateway. 


Return to Earth

Astronauts will ultimately return to Earth aboard the Orion spacecraft. Orion will enter the Earth’s atmosphere traveling at 25,000 miles per hour, will slow to 300 mph, then parachutes will deploy to slow the spacecraft to approximately 20 mph before splashing down in the Pacific Ocean.

We will establish sustainable lunar exploration within the next decade, and from there, we will prepare for our next giant leap – sending astronauts to Mars!
