On April 6, 2026, the Artemis II astronauts captured a striking image of Earth setting as their spacecraft orbited the Moon, echoing the iconic Earthrise photo taken by Apollo 8's Bill Anders 58 years earlier.

Created by the Smithsonian’s National Air and Space Museum, this collection includes detailed biographies of astronauts and scientists who worked on the program and interactive features on the technologies that made it possible.

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.

The flaw in Hubble's mirror was smaller than the width of a human hair, but fixing it required a space mission as complex as a Hollywood rescue story—with astronauts installing corrective optics like contact lenses for a giant eye in the sky.

On the night of July 20, 1969, Neil Armstrong stepped down the lunar module's ladder onto the moon's surface. The broadcast was watched by an estimated 650 million people—about a fifth of the then global population.

Not all parts of the space telescope's primary mirror focused incoming light to the same location, an effect known as spherical aberration. Because Hubble was designed to reside in low Earth orbit and be serviced by astronauts, service missions were deployed in the years after its launch to conduct repairs.

Hubble senior project scientist David Leckrone recalls initial public ridicule over the microscopic manufacturing error that put NASA's reputation at stake. In this behind-the-scenes interview, he breaks down the innovative fix deployed by space shuttle astronauts during Hubble's first servicing mission.

And why is the next cohort headed there? The geological conditions in Flagstaff, Arizona, can easily echo those of the moon, making the area a prime spot to train astronauts. This article explains how scientists crafted these training grounds and why astronomers are drawn to the nearly century-old city.

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.

Despite Apollo 11 starting as a 3,000-ton spacecraft, the only part of it that returned to Earth was the small command module, which splashed down in the Pacific Ocean carrying three astronauts and moon rocks.

From modulating our tides to impact our climate, Earth's lone natural satellite plays a key role forming the planet's habitat. Before diving into the rest of the resources on this page, check out NASA's overview of the basics of the Moon—how it got its name, its size and distance from Earth, its structure, and much more.

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.

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.

The gallery features Hopper's meeting with President Ronald Reagan, her attendance at the groundbreaking of the Grace Murray Hopper Service Center—a Naval data processing facility—and her Presidential Medal of Freedom ceremony.

Twelve Central Illinois residents are asked to share their thoughts on where they were when the first people landed on the Moon. This almost one-hour program is a collaboration of Eastern Illinois University's Booth Library, the EIU Department of History, and WEIU, and it premiered at EIU's Booth Library, January 24, 2019.

As the Apollo 11 astronauts prepared for their journey to the moon, two speeches were drafted for President Richard Nixon: one to be delivered upon the astronauts' success and another to comfort the public in case of failure. This interactive explores the creation of a believable version of the latter.

When Neil Armstrong stepped onto the moon on July 20, 1969, his first words, transmitted across the globe, became legendary. Decades later, historians still debate whether he meant to say "one small step for a man," and where the phrasing may have originated.

Take one small step today and experience the historic moon-landing through VR. This video showcases how VR is allowing the public to travel through space through the eyes of those who lived through it.

Established in 1958—a year after the Soviet Union launched Sputnik 1—the National Aeronautics and Space Administration has taken humanity into outer space and helped reveal the nature of the universe. Historic moments include the Apollo 11 mission putting humanity on the Moon and construction of the International Space Station.

While reviewing designs for instruments to be carried by future Mars rovers, Nye suggested adapting the function of a calibration tool, which would be used by the Spirit and Opportunity rovers to help calibrate the brightness and color of their panoramic cameras on the Martian surface.

Spacecraft have been taking pictures of Mars from space since 1965, when the Mariner 4 probe became the first to beam back an image of a planet other than our own. The technology has significantly evolved since then, with ultra-high definition resolutions revealing previously unseen surface features.

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.

When Apollo 11 astronauts stepped onto the moon in July 1969, it marked a dramatic win in the US-Soviet space race. The televised landing—broadcast across the globe—showcased American technological supremacy.

The US government adopted the new technology to support the development of the Apollo Guidance Computer, which would help astronauts fly to the moon. This drove manufacturing up and costs down, setting the stage for the modern computing era.

Margaret Hamilton and Ellen Fetter worked on MIT's 800-pound Royal McBee LGP-30 computer, which was fed binary code on paper tape to perform computations. Among the computations performed were those involving equations describing the motion of gas in a circulating fluid for Edward Lorenz, widely considered the father of chaos theory.

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 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 1972, Gene Cernan became the most recent person to walk on the moon during Apollo 17. This video revisits why the mission flew, what it aimed to achieve, and includes archival footage and later interviews with lunar module pilot Harrison Schmitt.

In 2021, astronaut Megan McArthur used a HoloLens to work alongside Earth-based engineers and make hardware replacements to the International Space Station's Cold Atom Lab, the first quantum science facility in Earth orbit. The facility cools atoms to near absolute zero to perform quantum chemistry experiments in a microgravity environment.

The honor was part of the 2019 series "100 Women of the Year," which spotlighted an influential woman for each of the years the publication had previously awarded a "Man of the Year." In its write-up, Hopper was described as having "paved the way for women everywhere to thrive in math, computer science, and service to their countries."

When planning to land on the moon, knowing the topography matters.
