Artemis Program

The Artemis Missions

The Artemis program was restructured in February 2026: Artemis III will test systems in Earth orbit in 2027, while Artemis IV will return humanity to the Moon in 2028.

Artemis III - Low Earth Orbit Test (2027)

Rendezvous & Docking

Rendezvous and docking tests in low Earth orbit (LEO) with one or both commercial landers: SpaceX Starship HLS and Blue Origin Blue Moon.

AxEMU Spacesuit Testing

First microgravity tests of the new AxEMU spacesuits developed by Axiom Space, which will later be used for lunar surface walks during Artemis IV.

Integrated Systems

Verification of life support, communications, propulsion and navigation systems of docked vehicles, in a safe orbital environment before the landing.

Artemis IV - First Moon Landing (2028)

Scientific Exploration

Two astronauts will descend to the lunar South Pole aboard Starship HLS to collect samples, study water ice deposits and conduct scientific experiments.

Historic Firsts

The first Moon landing since 1972, with the first woman and first person of color to walk on the lunar surface. Approximately 6 days on the surface.

Mars Preparation

The Moon serves as a testing ground for technologies and procedures needed for future human missions to Mars.

The Spacecraft

Space Launch System (SLS)

The SLS rocket is the most powerful launch vehicle ever built by NASA. At 98 meters tall with 39.1 meganewtons of thrust, it can carry over 27 tonnes to the Moon.

  • Height: 98 meters (322 ft)
  • Liftoff thrust: 39.1 MN (8.8 million lbf)
  • Payload to Moon: 27+ tonnes
  • Propulsion: 2 solid rocket boosters + 4 RS-25 engines

Orion MPCV

Orion Capsule

Orion (Multi-Purpose Crew Vehicle) is the capsule designed to transport astronauts into deep space. Built by Lockheed Martin, with the European Service Module provided by ESA.

  • Crew: up to 4 astronauts
  • Mission duration: over 21 days
  • Habitable volume: 316 cubic feet
  • Service module: ESA (European Service Module)

Starship HLS (Human Landing System)

SpaceX won the NASA contract to develop a Starship variant as the lunar lander. It will carry 2 astronauts from lunar orbit to the surface and back during Artemis IV.

  • Height: ~50 meters (~164 ft)
  • Crew: 2 astronauts for lunar descent
  • Propellant: Liquid methane + Liquid oxygen
  • Refueling: requires orbital refueling before mission
