The animals that paved the way for space travel

Before humans, the Soviet Union and the United States sent animals—including apes, dogs, and cats—to space during the Space Race.

Sputnik 1—launched in 1957—was Earth's first artificial satellite

Its launch accelerated US investment in the Space Race amid fears the Soviet Union had the technology to launch intercontinental nuclear warheads. It would be followed by Sputnik 2, which carried the first living being—a dog named Laika—to orbit.

Who’s in space right now?

Hundreds of people (and a few animals) have been to space since the first creatures flew past the Kármán line in 1947. There are a handful of astronauts aboard the International Space Station at any time, while others may be cresting space in...

View 60 years of NASA space exploration

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.

Soviet cosmonaut Yury Gagarin was the first human to journey into outer space

In 1961, aboard Vostok 1, the pilot orbited the Earth once for 108 minutes. On his return, he parachuted out of his capsule and landed in a field near present-day Space Conquerors Park, south of Moscow.

Space archaeology studies space trash in the context of heritage and social meaning

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.

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 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.

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.

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."

Meet Icarus the Second, the first English pig to fly

"When pigs fly" is an ironic phrase meant to express disbelief or impossibility, though it isn't as true today as it may once have been. This article details how a piglet dubbed "Icarus the Second" took flight in November 1909. Stashed in a basket...

The first flight on Mars carried a piece of the Wright plane with it

In April 2021, the solar-powered helicopter Ingenuity—attached to NASA’s Perseverance Mars rover—flew in what became the first controlled flight on a planet other than Earth. Carried with it was a piece of fabric from the famous 1903 Wright Flyer, a symbol of Ingenuity’s continuation of the Wright tradition.
