- Return Humans to the Moon: By landing astronauts on the lunar surface, Artemis will continue the legacy of the Apollo missions, which last put humans on the Moon in 1972.
- Establish a Sustainable Presence: Unlike Apollo, which was short-lived, Artemis will lay the groundwork for a permanent, human presence on the Moon, including lunar bases and habitats.
- Prepare for Mars Exploration: The Moon provides an ideal testing ground for technologies and systems that will be used for future Mars missions, such as life support systems, resource utilization, and long-duration space travel.
- Advance Science and Technology: Through Artemis, NASA hopes to uncover new scientific insights about the Moon, the broader solar system, and fundamental aspects of space travel.
Key Components of the Artemis Program
NASA’s Artemis program involves various components, from the spacecraft that will carry astronauts to the Moon to the lunar landers that will transport them to the surface. These components are integral to making the mission a success and include partnerships with international space agencies and private companies.
1. The Space Launch System (SLS)
At the heart of the Artemis missions is NASA’s Space Launch System (SLS), a powerful rocket designed to take astronauts beyond Earth’s orbit. The SLS will be the most powerful rocket ever built, with the ability to carry both crewed and uncrewed spacecraft to the Moon and other destinations in deep space.
The SLS is built in stages, with its Block 1 configuration designed to lift heavy payloads to the Moon. Future upgrades will increase its capability, allowing for more crewed missions and the delivery of cargo to the lunar surface. It will be paired with the Orion spacecraft to enable human missions to the Moon.
2. Orion Spacecraft
The Orion spacecraft, also known as the Crew Exploration Vehicle (CEV), is the crewed spacecraft that will transport astronauts to the Moon and back. With advanced life support systems, communication technology, and radiation shielding, Orion is designed for deep-space missions. The spacecraft can carry up to four astronauts and will be launched atop the Space Launch System.
Orion will be equipped with a crew module and service module. The crew module will house the astronauts during their journey to and from the Moon, while the service module will provide propulsion, power, and environmental control during the mission.
3. Lunar Gateway
One of the key innovations of the Artemis program is the Lunar Gateway, a space station that will orbit the Moon and serve as a staging point for crewed lunar missions. The Gateway will provide astronauts with a place to rest and resupply before making their journey to the Moon’s surface. It will also be used for scientific research and testing of deep-space technologies.
The Lunar Gateway will be a collaborative effort, with NASA working alongside international partners like the European Space Agency (ESA), Japan’s JAXA, and the Canadian Space Agency (CSA). The Gateway’s orbit will allow easy access to both the Moon’s near and far sides, offering flexibility for mission planning.
4. Lunar Landers
The Artemis program will employ a new generation of lunar landers to transport astronauts from the Gateway to the Moon’s surface. These landers will be developed through public-private partnerships, with NASA working with companies like SpaceX and Blue Origin. SpaceX’s Starship, for example, has been selected to serve as the lunar lander for the Artemis III mission.
The lunar landers will need to be equipped with advanced life support systems, mobility systems, and radiation protection to ensure the safety and comfort of astronauts as they work on the Moon’s surface. They will also be designed to operate in the Moon’s harsh environment, including extreme temperatures and low gravity.
5. Surface Habitats and Lunar Infrastructure
Beyond the landers, NASA envisions a sustainable lunar infrastructure that will allow astronauts to live and work on the Moon for extended periods. This will include surface habitats where astronauts can sleep, work, and conduct experiments. These habitats will need to be airtight, self-sustaining, and capable of providing food, water, and oxygen.
To support long-term lunar operations, Artemis will also use in-situ resource utilization (ISRU) techniques, allowing astronauts to extract resources from the Moon, such as water ice, to generate oxygen and fuel. This will reduce the need to transport everything from Earth, making a permanent lunar presence more feasible.
Artemis Mission Phases
The Artemis program is broken down into a series of progressively complex missions, with the first uncrewed mission scheduled for 2022 and the first crewed landing planned for 2025.
1. Artemis I (Uncrewed Test Mission)
Artemis I will be the first test flight of the Space Launch System and the Orion spacecraft. It will be an uncrewed mission designed to test the rocket and spacecraft’s systems, including the launch, flight, and return to Earth. This mission will pave the way for future crewed missions and ensure that all systems are functioning as expected before humans are onboard.
2. Artemis II (First Crewed Mission)
Artemis II will be the first crewed mission of the Artemis program. The astronauts aboard will fly around the Moon but will not land. This mission will allow NASA to test all crewed systems in deep space, including the life support systems, communication, and navigation technologies. The goal of Artemis II is to ensure that astronauts can safely travel to the Moon and return.
3. Artemis III (First Crewed Lunar Landing)
Artemis III will be the flagship mission of the program, marking the first crewed lunar landing since Apollo 17 in 1972. The astronauts will land on the Moon’s South Pole, a region that has never been explored before. This location is of particular interest due to the potential for water ice, which could be used for future human habitation and fuel production.
Astronauts will spend several days on the lunar surface conducting scientific experiments, collecting samples, and testing technologies for long-term lunar exploration. The goal of Artemis III is not only to return humans to the Moon but also to establish the groundwork for sustainable exploration.
4. Artemis IV and Beyond (Sustaining Lunar Presence)
After Artemis III, NASA plans to continue the Artemis program with additional missions, focusing on establishing a permanent presence on the Moon. Artemis IV will bring the necessary infrastructure to support long-term lunar exploration, including habitats, rovers, and ISRU technologies. Future missions will focus on building a permanent lunar base, allowing astronauts to live and work on the Moon for extended periods.
NASA’s long-term goal is to use the Moon as a testbed for Mars exploration. The technologies and systems developed for lunar missions will be critical for future missions to Mars, which NASA plans to launch in the 2030s.
The International Collaboration of Artemis
While NASA is leading the Artemis program, the agency is collaborating with several international partners to ensure the success of its missions. This includes the European Space Agency (ESA), the Canadian Space Agency (CSA), the Japan Aerospace Exploration Agency (JAXA), and the Australian Space Agency, among others.
ESA will provide the service module for the Orion spacecraft, while CSA will contribute the robotic arm for the Lunar Gateway. JAXA is also expected to play a significant role in the Gateway’s development. By fostering these international partnerships, NASA is creating a global effort to explore the Moon and prepare for future missions to Mars.
