Although it was only in 1942 that the first rocket reached the outer edges of Earth’s atmosphere, physicists and philosophers had dreamed of leaving our planet and exploring the cosmos for centuries before that. We take a tour of 51 milestones in space travel. 

1st century AD
Greek mathematician and engineer Hero of Alexandria is the first to explain jets of steam as thrust.

1044
In China, saltpeter-based incendiary devices are described and rockets (“fire arrows”) developed.

1066
One of the most famous sightings of Halley’s Comet is reported. It is depicted on the embroidered Bayeux Tapestry, which is over 68 m in length, which was completed in 1077 and portrays William the Conqueror’s invasion of England.

Johannes Kepler

Johannes Kepler

As early as 1608, natural philosopher Johannes Kepler dreams of a journey to the Moon.

1608
German philosopher, astronomer and theologian Johannes Kepler writes his novel Somnium, considered the first work of science fiction. His book, (not published until after his death) describes human spaceflight and description of the Earth as seen from the Moon.

1687
With his Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), Isaac Newton lays down the foundation of classical mechanics and spurs on far-reaching developments in astronomy.

Isaac Newton

Isaac Newton

The Englishman is the first scientist to formulate the law of gravity.

1865
French novelist Jules Verne publishes From the Earth to the Moon, describing a cannon with a 270m long barrel.

1870
In his short story “The Brick Moon”, Edward Everett Hale imagines a crewed space station built of bricks and is today considered the great-grandfather of the ISS as well as GPS.

1924
Written by Austrian Max Valier, The Advance into Space is the first book of science writing on the subject for a popular audience to be published in Germany. It takes its cue from spaceflight pioneer Hermann Oberth’s 1923 publication By Rocket into Planetary Space. The book had initially been rejected as a Ph.D. thesis.

Jules Verne

Jules Verne

Verne’s early works establish him as one of the greats of science fiction literature.

 

1931
After takeoff in Augsburg, Germany, Swiss scientist Auguste Piccard and his assistant Paul Kipfer achieve a stratospheric rise in a pressurized capsule attached to a hydrogen balloon—reaching an altitude of almost 17 km.

1942
On October 3, an A4, long-range missile is launched from Usedom Island off Germany’s Baltic coast and reaches a height of 84.5 kilometers—making it the first man-made object to reach the boundaries of space. From 1944, the rocket is referred to as the V2.

4 October 1957
While the first episode of the American sitcom Leave it to Beaver is being broadcast, a Soviet rocket carries Sputnik 1—an aluminum ball just under 60 cm in diameter and the first satellite—into orbit around the Earth. The Sputnik crisis triggers the space race, as the Soviet Union and U.S. compete for dominance in space. Sputnik 1 orbits the Earth 1,400 times in 92 days

2 November 1957
The Soviets launch Sputnik 2—and this time, a dog named Laika is on board. She is the first living creature to leave Earth but dies a few hours into her journey from overheating and stress. The mission is nevertheless regarded as a success and serves as an important stepping stone toward the first human space flight, undertaken by Yuri Gagarin.

6 December 1957
Intended as the Americans’ first launch vehicle for a satellite, the Vanguard rocket loses thrust, falls back onto the pad and explodes. The national press enters into a game of one-upmanship in coining scornful names for the failure, riffing on the Soviet success—flopnik, goofnik, kaputnik, nullnik, oopsnik, stallnik and stayputnik.

Sputnick 1957

Sputnick 1957

In 1957, the Soviet Union blasts the first satellite into Earth’s orbit. Sputnik 1 is an aluminum ball of just under 60 centimeters in diameter.

1 February 1958
With the Explorer 1, the U.S. successfully puts its first artificial satellite into orbit around the Earth. It is the world’s third satellite following Sputnik 1 and 2. A two-meter-long cylinder, Explorer 1 is very different from the spherical Sputnik design. What’s more, it’s also significantly lighter. After spending 12 years in space, Explorer 1 burnt up on re-entry on March 31, 1970 about 100 kilometers above the planet’s surface.

29 July 1958
U.S. President Eisenhower signs the National Aeronautics and Space Act, which provides for the creation of the National Aeronautics and Space Administration (NASA). The new agency commences work on October 1, 1958. NASA’s vision is “To improve life here, to extend life to there and to find life beyond.”

4 October 1959
The Soviet Union’s Lunik 3 provides the first images ever seen of the far side of the Moon. Automatically developed on board and then transmitted to Earth, the pictures represent another success for the Soviets in the space race

12 April 1961
Soviet cosmonaut Yuri Gagarin is the first person to travel into space. After entering Earth orbit, Gagarin reports via radio, “I can see Earth. I am looking at the clouds. Beautiful, so beautiful!” The cosmonaut passes over the Soviet Union, the Pacific, the southern Atlantic, Africa and, in skimming Turkey, the edge of Europe. In the U.S., the flight elicits similar reactions to the Sputnik crisis four years earlier. On return from space, Gagarin is given a hero’s welcome in the Soviet Union.

In their Soviet Motherland the cosmonauts were celebrated like popstars.

5 May 1961
Alan Shepard is the first American in space. Unlike Gagarin, however, his voyage is not an orbit of the Earth but merely a suborbital parabolic flight. He reaches a height of 187 km and splashes down safely in the Atlantic 15 minutes later.

25 May 1961
President John F. Kennedy announces the Apollo program to the U.S. Congress and the nation, saying: “I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to Earth. No single project in this period will be more impressive to mankind, or more important in the long-range exploration of space; and none will be so difficult or expensive to accomplish.”

20 February 1962
John Glenn is the first American to orbit the Earth.

16 June 1963
Valentina Tereshkova is the first woman in space, completing 48 orbits of the Earth in three days. An amateur skydiver, she was recruited together with three other women for a special female cosmonaut corps.

18 March 1965
Soviet cosmonaut Alexei Leonov is the first person to perform a spacewalk, spending 10 minutes outside his ship. A tether of just under five meters secures him to his craft. But the extra-vehicular activity almost ends in disaster as Leonov’s suit balloons so badly out of shape in the vacuum of space that he initially cannot squeeze back inside the airlock. Only after releasing a valve on his suit can he get back in.

21 July 1969
“Contact Light” With these words, Neil Armstrong and Buzz Aldrin land Apollo 11 on the Moon. “Houston, Tranquility Base here. The Eagle has landed.” What follows is an even more famous line: “That’s one small step for a man, one giant leap for mankind.” Just a year earlier, Armstrong narrowly escaped death during training for the lunar landing. With the stars and stripes planted on the Moon, the United States won the race to the Moon. The Soviet Union turns its efforts toward building a permanently crewed space station.

Voyager 1 embarks on its journey to the edge of our solar system. It carries on board gold-plated copper phonograph records, dubbed the Voyager Golden Records, which contain sounds and images relating to human life. Among other things, the record cover features instructions for playback and a map indicating the location of our sun. Sound recordings include spoken greetings in 55 languages. The final greeting is in English and was spoken by then six-year-old Nick Sagan, son of Carl Sagan, the astronomer who oversaw the records’ creation. He says, “Hello from the children of planet Earth.”
