On April 12, 1961, Soviet cosmonaut Yuri Gagarin became the first human in space

In 1961, Soviet cosmonaut Yuri Gagarin became the first human to orbit Earth, deepening US fears of falling behind in the space race. Watch archival footage to see why the mission was such a historic turning point.

Fueled by Cold War competition, the Apollo program put humankind on the moon

Despite the US starting the space race behind the Soviet Union, which had put a cosmonaut into space in 1961, the successful landing of Apollo 11 on the moon in 1969 was seen as a defining victory for America.

The space race ended with a handshake in orbit in 1975

On July 17, 1975, American and Soviet astronauts docked their spacecraft during the Apollo–Soyuz mission, symbolically ending the space race and marking the first joint spaceflight between Cold War rivals.

A look at the foods eaten by astronauts during and after the space race

After John Glenn became the first American to demonstrate that eating in space was possible by eating apple puree out of a tube, meals were prepared for astronauts to meet an approximately 2,800-calorie-a-day requirement via freeze-dried foods. Meal quality gradually improved throughout the Apollo program, including the Apollo 8 crew's nondehydrated Christmas meal in 1968.

The Russian Federal Space Agency enabled the first space tourism journey

NASA refused to take Dennis Tito, who had no formal training as an astronaut, up to the International Space Station. Instead, the American engineer and entrepreneur traveled aboard the Soyuz TM-32 mission and described the initial experience of microgravity after engine shut-off as the "most spectacular" part of the flight.

The Challenger disaster ended NASA's plan to fly ordinary Americans in space

The explosion of the Challenger halted NASA's civilian spaceflight ambitions for decades, including plans to send teachers, journalists, artists, and other nonastronauts into orbit—an effort aimed at building public support that quietly disappeared after the 1986 disaster.

The animals that paved the way for space travel

The history of animals in space exploration is often overlooked. Before humans first made their way to space in 1961, fruit flies, primates, and canines preceded us. Watch this video for a further appreciation of the contributions and sacrifices made by animals for scientific progress.

Blue Origin, Jeff Bezos’ aerospace company, sent its first passengers to space in 2021

Founded in 2000, Bezos spent many years working on the company as a side project before it became more well-known around 2004, when a plot of land in Texas was purchased as a launch site for the company’s rockets. He has said that the goal of Blue Origin is to build “reusable space vehicles.” This resource details what passengers experience from takeoff to landing on a Blue Origin flight.

Explore a timeline of every mission to Mars through 2020

The US has conducted the most missions (23) and has the highest success rate (74%), followed by Russia (18 missions at 5%). The first successful orbiter was Mariner 4, while Viking 1 was the first successful lander.

See who is in space right now

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.

India's space program began in a church at Earth's magnetic equator

As the US pushed to land a man on the moon, NASA looked for global partners to help map the conditions of the sky above Earth for launches. After Pakistan's initial attempt was sidelined, India pushed to be that partner. This long read details key episodes of frugality and ingenuity in India's space race, including its beginnings at St. Mary Magdalene Church in Thumba.

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.

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.

Anticipating moon tourism by 2000, Pan Am issued 'First Moon Flights' club cards

More than 93,000 cards were issued between 1968 and 1971, creating a waitlist that began when Gerhard Pistor, an Austrian journalist, visited a Viennese travel agency to request a flight to the moon. The cards were issued at no cost and numbered in the order they were issued.

Eleven deaf men played a pivotal role in America's human spaceflight program

In the mid-20th century, 11 deaf men volunteered for a series of experiments that offered unprecedented insights into the effects of weightlessness on the human body. Most of the men had become deaf in early childhood as a result of spinal meningitis, a condition known to damage the vestibular system and make them less susceptible to motion sickness. For a decade, these men participated in extreme motion sickness situations, including living in a slowly spinning room, spending time in centrifuge pods designed to simulate hypergravity, and flying in parabolic flights sometimes referred to as the "Vomit Comet."
