Yuri Gagarin is technically a cosmonaut he was the first Russian man to go to space, orbiting the Earth on April 12 of 1961. The achievement was highly symbolic at the height of the Cold War, in the early years of the space race. Gagarin became an international celebrity as a result.

John Glenn was the first American to orbit the Earth, aboard Friendship 7 on February 20, 1962. He later became the oldest person to fly in space, at age 77, aboard space shuttle Discovery in 1998.

Neil Armstrong may be the most famous astronaut of all, as the first man to step foot on the moon, and the speaker of the phrases “The Eagle has landed” and “That’s one small step for man, one giant leap for mankind”. The latter sentence as rendered is a contradiction, leading to much discussion about whether Neil Armstrong actually said “a man“‘.

Alan B. Sheppard became the second man in space—and the first American—aboard Mercury mission MR-3, on May 5, 1961. Later, he returned to space as commander of Apollo 14, the third U.S. mission to the moon. Shepard piloted the lunar module and famously hit two golf balls on the lunar surface.

Marc Garneau became Canada’s first man in space on mission STS 41-G, the first to carry an IMAX camera. Garneau flew a total of three space missions and was later the president of the Canadian Space Agency. He is currently a Liberal member of parliament for Westmount—Ville-Marie.

Buzz Aldrin piloted the lunar module for the Apollo 11 mission and followed Neil Armstrong from the lander to the lunar surface, making him the second man to set foot on the moon. It was his second space flight, after Gemini 12.

Space Shuttle

The Space Shuttle made traveling in space like flying a plane. Space travel was no longer limited to trained astronauts. Space Shuttle passengers can now include scientists, doctors and other people needed to conduct experiments in space. The Space Shuttle has become the major launching vehicle for NASA. The Space Shuttle can take satallites into space, and it can also bring them back to Earth for repair.

Rover

A rover (or sometimes planetary rover) is a space exploration vehicle designed to move across the surface of a planet. Some rovers have been designed to transport members of a human spaceflight crew others have been partially or fully autonomous robots.

satellite

A satellite is an object in space that orbits or circles around a bigger object. There are two kinds of satellites: natural (such as the moon orbiting the Earth) or artificial (such as the International Space Station orbiting the Earth).

The Intenational Space Station

The International Space Station is a space station, or a habitable artificial satellite, in low Earth orbit. It is a modular structure whose first component was launched in 1998.

Sputnik

Sputnik 1 was the first artificial Earth satellite. It was a 58 cm diameter polished metal sphere, with four external radio antennas to broadcast radio pulses. The Soviet Union launched it into an elliptical low Earth orbit on October 4 1957

Hubble Scope

The Hubble Space Telescope (HST) is a space telescope that was launched into low Earth orbit in 1990, and remains in operation. With a 2.4 meter (7.9 ft) mirror, Hubble's four main instruments observe in the near visible, and near infrared spectra. The telescope is named after the astronomer Edwin Hubble.

A telescope is a optical instrument designed to make distant objects appear nearer, containing an arrangement of lenses, or of curved mirrors and lenses, by which rays of light are collected and focused and the resulting image magnified.
