Space Exploration

November 14, 1971

NASA’s Mariner 9 reaches the planet Mars and becomes the first man-made object to orbit another planet. Mariner 8 was scheduled to be the first, however due to launch problems it failed to make it out of Earth’s atmosphere. The Soviet Mars 2 and Mars 3 space probes reached the planet on November 27 and December 2 respectively.

Mariner 9 completed its mission of photographing the surface of Mars, transmitting 7,329 images covering 100% of the planet’s surface. While out of fuel, Mariner 9 still orbits Mars to this day, expected to stay in orbit until about the year 2022 when it will enter the planet’s surface and either burn up or crash into the surface.

The Soviet Union launches Sputnik 2, the second spacecraft launched into Earth orbit and the first spacecraft to carry a living creature into orbit. Laika, a Siberian Husky dog, unfortunately only survived a few hours into the flight and died from stress and overheating. The Soviets had planned to euthanize Laika regardless, as Sputnik 2 did not have de-orbiting or reentry technology designed into the spacecraft.

Russia launches Soyuz TM-31, carrying the first crew to the International Space Station. The ISS has been continuously manned since this first mission.

October 11, 1958

NASA launches Pioneer 1, the first spacecraft launched by the newly formed space agency. Originally intended to fly by the Moon, a launch malfunction due to a programming error caused Pioneer 1 to only attain a ballistic trajectory, which caused it to fall back to the Earth after 43 hours of flight. However, some useful scientific data was returned by the spacecraft.

October 4, 1957

The first man-made satellite to orbit the Earth, Sputnik 1, is launched from Baikonur, Kazakhstan, marking what is now considered the beginning of the Space Age. Surprising the world with its successful launch, Sputnik triggered the Space Race between the Soviet Union and United States ushering in an era of rapid advancement in the field of space exploration. After 3 months in orbit, Sputnik reentered the Earth’s atmosphere and burned up on January 4, 1958.

After fourteen years in space, eight of those as the first man-made object orbiting Jupiter, the unmanned NASA spacecraft Galileo is sent into the atmosphere of the giant planet. NASA decided to end Galileo’s mission in this manner in order to avoid any possibility of it colliding with one of Jupiter’s moons and potentially contaminating it with bacteria from Earth. How sanitary of them.

September 17, 1976

NASA rolls out the first Space Shuttle, Enterprise, from its assembly facility to a waiting crowd. Included in the crowd was a delegation of actors from the Star Trek TV series. Originally to be named Constitution, a write-in campaign by Star Trek fans convinced President Gerald Ford and NASA to rename the Space Shuttle.

The Enterprise was a prototype shuttle, designed for the early testing phase of the Space Shuttle program. It was built without engines or a functional heat shield. While it performed various atmospheric test flights, and was originally intended to be retrofitted for spaceflight, it was determined that it would be less expensive to simply build new shuttles. Therefore the Enterprise never did actually fly into space.

September 14, 1959

The Soviet space probe Luna 2 crashes onto the surface of the Moon, becoming the first man-made object to reach the Moon, as well as the first man-made object to reach any celestial body.

September 11, 1985

The International Cometary Explorer passes through the gas tail of comet P/Giacobini-Zinner, the first ever man-made object to pass through the tail of a comet.
