VideoHear the countdown and see how NASA’s Space Launch System (SLS), the world’s most powerful rocket, will send the Orion spacecraft to the Moon on the Artemis 1 Mission. This video takes you through the pre-launch sequence at NASA’s Kennedy Space Center in Florida and through all the flight operations as SLS launches Orion and sends it on to lunar orbit.

The Artemis program will return humans to the Moon by 2024. Artemis I, the first Artemis mission, will test all of the human rated systems in deep space — including the Orion spacecraft and Space Launch System rocket. Credit: NASA

The first test flight in 2020, Artemis 1, will carry an uncrewed Orion space capsule to the moon to test the performance of the integrated system. SLS also will carry 13 small satellites, each about the size of a shoebox, that will be deployed in deep space.

 
 

THE Artemis moonprogram

Last update

NASA has just announced a major step forward in its plan to send astronauts to the Moon by 2024: task order awards to three commercial partners to deliver NASA science and technology instruments to the Moon. This is one of many recent milestones to come in our new Artemis program to explore the Moon.

On April 9, 2019, NASA expressed its commitment to a timeline of landing humans on the lunar south pole by 2024. The agency’s lunar exploration plans are based on a two-phased approach: the first is focused on speed – landing astronauts on the Moon in five years – while the second will establish a sustained human presence on and around the Moon by 2028. NASA will use an orbiting lunar outpost called Gateway to access the Moon. The agency is targeting launch of the power and propulsion element in late 2022.

Planning this program requires many different pieces, including new technologies and partnerships. Developments on all fronts are moving ahead rapidly.

The SLS is designed for deep space missions. It will send the Orion spacecraft or other cargo to the Moon, which is nearly 1,000 times farther than where the space station resides in low-Earth orbit, at about 400 kilometers. The rocket have the power to help the Orion spacecraft to reach the speed of at least 24,500 mph needed to break out of low-Earth orbit gravity and travel to the Moon. 

Artemis I, the first integrated flight of SLS and Orion, uses the Block 1 configuration, which stands 322 feet, and weighs 5.75 million lbs. The SLS will produce 8.8 million lbs. of maximum thrust, 15 percent more thrust than the Saturn V rocket.

For Artemis I, theBlock 1 will launch an uncrewed Orion spacecraft to an orbit 40,000 miles beyond the Moon, or 280,000 miles from Earth. This mission will demonstrate the integrated system performance of SLS, Orion and Exploration Ground Systems prior to a crewed flight.

The Artemis II mission will send astronuats on a flight to orbit the Moon. These missions pave the way for landing astronauts on the Moon in 2024, during the Artemis III mission.

 

 

ORION

 

NASA’s Orion spacecraft is an exploratory vehicle designed for longerduration flights beyond the Moon.
Exploration Mission-1 (EM-1):
Orion spacecraft will travel beyond the Moon, enter a distant retrograde orbit around the Moon and return to Earth unmanned
Exploration Mission-2 (EM-2):
First crewed test flight of the Orion spacecraft, currently targeting a June 30, 2022 launch. EM-2 will see a crewed spacecraft complete a slightly different flight path. The mission involves:
• One revolution in Low Earth Orbit (LEO) parking orbit to verify basic Orion systems functionality and deploy solar arrays.
• A single 42-hour Highly Elliptical Orbit (HEO) intermediate checkout orbit allows characterization of the Orion vehicle system performance prior to committing to a cis-lunar flight.
• Trans Lunar Injection (TLI) burn using Orion Service Module (SM) main engine, which sends Orion on a lunar flyby and free return.
• Skip reentry at lunar return velocities to splashdown off the coast ofSan Diego.
