This archive includes the many steps it took to put together each Voyager probe. Photos focus on individual parts, like the 8-track tape deck, the large dish-shaped antenna, and its long arm magnetometer boom.

With more than 1.7 million observations made since 1990, the Hubble Space Telescope has captured images of space missions, planets, stellar nurseries, interstellar comets, star clusters, galaxies, and more. This search tool allows users to sort and filter across these celestial objects to explore over 35 years of Hubble's astrophotography.

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.

STS-51L's planned seven-day mission included deploying satellites, studying Comet Halley, conducting fluid dynamics experiments, and broadcasting live lessons from orbit—routine scientific and educational tasks that were never carried out after the shuttle was lost shortly after launch.

This collection compiles shots of well-known locations, such as US national parks, and natural features, including aurora borealis and fall foliage, to provide a high-level view of Earth's surface.

Astronauts' initial small step for mankind may standout, but how many steps have we taken so far? Space and moonwalks further our understanding of spaceflight, celestial bodies, and space itself. Created to resemble a constellation map, this chart...

The series illustrates the population of objects orbiting Earth as of February 2024, using data from US Space Command. These include active satellites, defunct spacecraft, rocket bodies and debris fragments larger than roughly 10 centimeters in low Earth orbit.

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.

As of 2023, more than 600 astronauts and 63 space tourists have seen Earth from space, experiencing a life-changing perspective shift as they view the entirety of our home planet.

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.

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.

Space shuttles delivered storage carriers, docking compartments, airlocks, solar arrays, and labs, which were assembled in low Earth orbit. The station’s Canadarm2 robotic arm, alongside maneuvering spacewalkers, has assisted with this assembly since its installation in 2001.

In the 1970s, Rockwell International, a NASA contractor, and others investigated manufacturing passenger modules that could fit into the Space Shuttle's payload bay. NASA also opened spaceflights to nongovernment professionals, but many such programs were ended after the Challenger disaster, which killed the first Teacher in Space participant.

While searching for World War II wreckage near Cape Canaveral, Florida, for a documentary, divers discovered debris on the seafloor that NASA later confirmed to be a piece of Space Shuttle Challenger wreckage. The piece is at least 15-by-15 feet in size and partially buried under sand.

On Feb. 1, 2003, Space Shuttle Columbia broke apart during reentry, killing all seven astronauts aboard. The tragedy revealed long-ignored safety warnings, leading NASA to ground the shuttle fleet and overhaul its safety culture.

Aboard the fictional USS Hubble, users can choose their own adventure to investigate the solar system, our galaxy, and the universe beyond. Each option directs users to a real image accompanied by relevant information and additional media elements, such as a time-lapse of the moon Phobos orbiting Mars.

The tool enables users to learn about the daily events that occurred on the ISS since continuous human occupancy began on November 2, 2000. Upon selecting a date in the calendar, users can explore activity logs, relevant news, and multimedia content, including videos, photographs, and audiologs, from the onboard crew.

While the James Webb telescope collects an astounding amount of scientific data, a major part of its allure is its ability to return stunning, high-resolution images. These images include nearby stars, distant galaxies, and some of the oldest structures in the universe.

Announced by President Ronald Reagan, the program drew more than 11,000 teacher applicants nationwide. Christa McAuliffe was selected to fly on STS-51L, with plans to teach live lessons from orbit before the Challenger disaster ended the mission.

Over 600 people have been in space since the space race took off decades ago, with roughly 10 in space at any given time, typically operating the world's growing number of space stations. This fun, simple tracker keeps up on who is in space right now and provides links to each space traveler's profile.

Learn how and why we explore our solar system and beyond with space exploration missions, and find out how you can get involved.

NASA's Extravehicular Mobility Unit has been in use since the 1980s, with 11 units of the model in existence and four in active use on the ISS at any given time. It consists of 11 layers, a primary life support system (which resembles a backpack), a drinking bag, and more.

This collection includes original mission bulletins, engineering and planning documents, and interview segments from more than 80 Viking team members who made the historic exploration of Mars’ surface by a lander possible.

As part of NASA's early outreach ideas tied to the Teacher in Space program, Sesame Street's Big Bird was briefly considered for a Challenger flight, but the plan was dropped because the oversized costume could not fit safely inside the shuttle.

The US has sent the most astronauts to the ISS, with 170 visitors, followed by 64 from Russia, 11 from Japan, and nine from Canada. American astronauts Michael E. Lopez-Alegria and Peggy A. Whitson and Russian cosmonauts Yuri Malenchenko and Fyodor Yurchikhin have the most trips, with five each.

Taken over 11 days between 2003 and 2004, when the space telescope was aimed at a seemingly empty patch of the sky, the Hubble Ultra-Deep Field revealed about 10,000 sources of light, most of which are entire galaxies. This visualization expands the 2D image into a 3D view spanning 12 billion years.

James Harding logged every flight he had flown in a software program and rendered the results into 3D globe animations, charts, graphs, and more. You can view the visualizations here, along with career stat breakdowns and a description of his project.

The 1986 explosion of the space shuttle shortly after liftoff killed seven crew members and grounded NASA's space fleet. Scientists used the downtime to refine ground control software and upgrade telescope instrument sensitivity, but maintaining the telescope's clean room storage cost NASA approximately $6M per month.

A Hughes Aircraft engineer with a background in electrical engineering, payload specialist Gregory Jarvis was assigned to STS-51L to study how fluids and satellite propellants behave in weightlessness during shuttle maneuvers.
