Learn about the missions comprising the Artemis program, which aim to return humanity to the moon and develop the technology for future human space exploration.

The Artemis program to bring humans to the moon for the first time since 1972

Using NASA's next-generation megarocket, the Space Launch System, Artemis I will take an uncrewed spacecraft on a 42-day journey around the moon. Subsequent missions plan to land the first woman on the lunar surface.

Ahead of constructing a lunar base as part of the Artemis program, NASA will send a fleet of hopping drones to scout the moon's south pole.

A gallery of shots taken during the lunar flyby of Artemis 2

On April 6, 2026, the four-person Artemis 2 crew took photos of "earthset" and "earthrise" from the Orion spacecraft window during their lunar flyby. It was the first time humans had flown around the moon in over 50 years.

Why are we finally returning to the moon after 50 years?

After 50 years, NASA is heading back to the moon. Artemis missions will push beyond Apollo, landing astronauts on the moon's south pole by 2027. But why the long wait? Budget cuts, shifting priorities, and outdated tech stalled lunar exploration—until now. With new goals and modern tech, NASA is ready to return.

The space race of the 21st century is focused on a permanent lunar outpost

After decades of dormancy, NASA and SpaceX hope the Artemis program will provide opportunities for lunar resource extraction. Countries like India, China, and the UAE have also shown interest in developing future lunar economies.

NASA plans to build a lunar-orbiting space station to support future missions to Mars

How NASA plans to build a lunar base, from roads to habitats

The Apollo program aspires to return humans to the moon—and to build humanity's first permanent habitat on its surface. The project involves complex construction plans, including creating roads from moon dust, baking bricks to build habitats, and more.

In 2024, China announced plans to establish an international lunar research station

The strategy, which runs until 2050, focuses on advancing space science, fostering technological innovation, and exploring habitable planets and extraterrestrial life, beginning with landing astronauts on the moon before 2030.

The Apollo program built US space technology and showcased its Cold War dominance

Beyond landing humans on the moon for the first time, Apollo served to advance rocket engineering and guidance systems through crewed and uncrewed missions. By Apollo 15, the Lunar Roving Vehicle was developed and driven on the moon.

NASA was founded in response to early Soviet space achievements

Although starting behind in the Space Race in 1958, NASA became a global leader in humanity's exploration of space with the Apollo program, which placed astronauts on the moon. Since then, it has been responsible for the construction of multiple telescopes, the International Space Station, and development of the Artemis program to return humans to the Moon before eventually reaching Mars.

Alongside the construction of the first lunar base with help from SpaceX's Starship Human Landing System, transported astronauts would establish a sustainable human presence through the construction of lunar dust shields, light-bending towers, and 3D-printed habitats.

The Space Launch System: NASA's most powerful rocket ever

The Space Launch System is intended to be the most powerful rocket ever built by NASA. Possible missions include returning to the moon and perhaps even reaching Mars. This speculative and mostly silent video uses animation to explore the inner workings of the SLS, showing it launching and in space flight.

Only 34% of Americans supported the Apollo program in 1967

After a fire killed three astronauts on the launchpad of Apollo 1, the public became ambivalent about funding the multibillion-dollar program until the successful moon landing in 1969. The landers alone cost $388M, while each spacesuit cost $100,000.

The Polaris Dawn was a privately crewed spaceflight

SpaceX's Crew Dragon capsule Resilience spent five days in low Earth orbit as part of the first of three planned missions under the name Polaris Dawn. The historic journey took participants farther away from our planet than anyone has been since the Apollo missions.

View the docket of future SpaceX launches

SpaceX has established an efficient schedule for launches of ISS crew shuttles and Starlink satellites, with blastoffs occurring just under once every four days in 2023—a pace that has since accelerated as the company has won more contracts.

Scientists used to speculate about life on the moon

In the 17th century, Galileo's observations suggested the moon could be inhabited, leading to fictional speculations about lunar life. In the 19th century, stories were published claiming the discovery of various creatures, including human bats. The Apollo missions in the 20th century explored the possibility of life there, but further exploration showed this idea to be less likely than before.

When retired, the International Space Station will undergo a controlled de-orbit

With plans to transition low-Earth orbit operations to private entities, the ISS is expected to be retired by 2030, using a SpaceX de-orbit vehicle. Although reentry will burn up most hardware, NASA intends for any surviving debris to fall into an uninhabited ocean area.

Why haven’t humans reached Mars?

Mars remains the most viable interplanetary destination due to its relatively habitable orbit. There are many challenges, however, including the huge distance to Mars, the need for advanced propulsion systems, uncertainty over the impacts of long-duration space travel on astronauts, and the need for safe landing techniques and equipment to handle Martian conditions. Human-manned missions to Mars are not likely to occur until the 2030s at the earliest.

Apollo astronauts left items in the moon's 'toss zone,' including golf balls, family photos, and bags of human waste, to make room for lunar rocks.

Some orbiting objects, such as Elon Musk's Tesla, have symbolic or historical importance, despite being functionally worthless. The oldest human-made object in Earth's orbit is Vanguard 1, a grapefruit-sized satellite launched in 1958. The strangest may be an experimental, inflatable space station containing live cockroaches.

Orbital spaceflight requires reaching 23 times the speed of sound

After the spacecraft accelerates up to at least 17,500 miles per hour, space tourists can travel in elliptical orbits hundreds of miles above Earth for days or weeks at a time. Suborbital flights instead max out at about 2,200 miles per hour and travel only 50 to 70 miles above Earth's surface for a few minutes.
