The Cold War between the United States and former Soviet Union gave birth to the space race and an unprecedented program of scientific exploration. The Soviets sent the first person into space on April 12, 1961. In response, President John F. Kennedy challenged our nation “to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to earth.” It took eight years and three NASA programs -- Mercury, Gemini and Apollo – but the United States got to the moon.

Project Mercury, the first U.S. program to put humans in space, made 25 flights, six of which carried astronauts between 1961 and 1963. The objectives of the program were: to orbit a human spacecraft around Earth, to investigate a person’s ability to function in space, and to recover both the astronaut and spacecraft safely. More than 2 million people from government agencies and the aerospace industry combined their skills, initiative and experience to make the project possible. Mercury showed that humans could function for periods up to 34 hours of weightless flight.

NASA research mathematician Katherine Johnson did the trajectory analysis for Alan Shepard’s historic mission. Johnson worked at NASA’s Langley Research Center from 1953 to 1986. She and many other women made critical technical contributions to the space program.

The Gemini program primarily tested equipment and mission procedures and trained astronauts and ground crews for future Apollo missions to the Moon. The program’s main goals were: to test an astronaut’s ability to fly long duration flights (14 days); to understand how a spacecraft could rendezvous and dock with another vehicle in Earth orbit; to perfect re-entry landing methods; and to further understand the effects of longer spaceflights on astronauts. NASA selected “Gemini” because the word is Latin for “twins,” and the Gemini was a capsule built for two.

Exactly eight years, one month and 26 days after President Kennedy challenged Americans to reach for the Moon, Project Apollo landed the first humans on the lunar surface and returned them safely to Earth. The Apollo program also developed technology to meet other national interests in space, conducted scientific exploration of the Moon, and developed humanity’s capability to work in the lunar environment.

The Apollo program was hit by tragedy as the first crew prepared to fly. On Jan. 27, 1967, fire swept through the Apollo 1 command module during a preflight test on the Cape Kennedy launch pad. Astronauts Gus Grissom, Ed White, and Roger Chaffee lost their lives. NASA was not deterred, but rather changed how things were done to ensure the safety and success of future missions.

The famous 'Earthrise' photo from Apollo 8, the first human mission to the Moon. On Christmas Eve, 1968, as one of the most turbulent, tragic years in American history drew to a close, millions around the world watched and listened as Apollo 8 astronauts Frank Borman, Jim Lovell and Bill Anders -- first humans to orbit another world – read from the Bible’s Book of Genesis.

On July 20, 1969, Apollo 11 Commander Neil Armstrong placed the first human footstep on the Moon. Here he’s shown working at an equipment storage area on the lunar module. This is one of the few photos that shows Armstrong during the moonwalk.

A makeshift arrangement of equipment, parts and duct tape on the Apollo 13 Lunar Module (LM) saved the crew’s lives after an oxygen tank explosion in the Service Module left them with the LM to use as a “lifeboat.” Using materials only found on the spacecraft, NASA engineers on the ground designed and tested a system that removed carbon dioxide from the LM; the Apollo 13 crew then made the system onboard, April 17, 1970, and returned safely to Earth.
In 1973, Skylab expeditions paved the way for the International Space Station. The four, windmill-like solar arrays were attached to the Apollo Telescope Mount. Observations of the Sun were one of this space lab program’s primary achievements.

In the 1970s, U.S.-Soviet political tensions that had accelerated the space race began to thaw. Competition gave way to cooperation between the two nations with the Apollo-Soyuz Test Project. International collaboration among many nations would become the norm during the space shuttle era and current cooperation in human spaceflight with the International Space Station. These partnerships have taught us more about the universe, improved our lives at home, and expanded the possibilities for future exploration into deep space.

Over 30 years, NASA's space shuttle fleet—Columbia, Challenger, Discovery, Atlantis and Endeavour—flew 135 missions and carried 355 different people to space. Humanity's first reusable spacecraft, the space shuttle carried people into orbit repeatedly; launched, recovered and repaired satellites; conducted cutting-edge research; and built the largest structure in space, the International Space Station. The space shuttle pushed the bounds of discovery ever farther, requiring not only advanced technologies but also the tremendous efforts of thousands of civil servants and contractors throughout NASA's field centers and across the nation. Tragically, NASA lost two crews of seven in the 1986 Challenger accident and the 2003 Columbia accident.

One of many steps in assembling the International Space Station, Space Shuttle Atlantis delivered the S0 Truss Structure (the big set of solar panels across the top of the picture), which the crew installed on top of the Destiny module.
The International Space Station is a model for global cooperation and scientific advancements that is enabling growth of private industry in low-Earth orbit and development of new technologies to advance human space exploration. Built between 1998 and 2011, the space station has housed humans continuously since Nov. 2, 2000. Because molecules and cells behave differently in space, research in microgravity helps advance scientific knowledge. The space station is a U.S. National Laboratory, which the Center for the Advancement of Science in Space (CASIS) manages for research investigations that improve life on Earth. NASA has contracted with commercial companies SpaceX, Orbital ATK, and Sierra Nevada Corporation to deliver science investigations, cargo, and supplies to the crews living in space, and soon Boeing and SpaceX will transport astronauts to and from the station.

Nine crew members gathered in the International Space Station’s Kibo laboratory represent four of the five participating space agencies. The station is a partnership of 15 nations through NASA, ESA (the European Space Agency), the Canadian Space Agency (CSA), the Japan Aerospace Exploration Agency (JAXA), and Roscosmos, the Russian Federal Space Agency. “Kibo” means “hope” in Japanese. All crew members speak English and Russian.

American, Japanese, and Russian cargo spacecraft bring science investigations and supplies to the station about 10 times a year. They don’t go away empty handed— the Orbital ATK Cygnus, JAXA’s HTV, and Russian Progress ships take out the trash and burn up during reentry while the SpaceX Dragon lands in the Pacific Ocean to return science and hardware to researchers on Earth.
