Yuri Gagarin
Every year as the anniversary of the first human spaceflight approaches, I receive calls inquiring about the validity of Yuri Gagarin’s claim as the first human in space. The legitimate questions focus on the fact that Gagarin did not land inside his spacecraft. The reasoning goes that since he did not land inside his spacecraft, he disqualified himself from the record books. This might seem to be a very reasonable argument, but Gagarin remains the first man in space. -
Alan Shepard
Alan Bartlett "Al" Shepard, Jr. (November 18, 1923 – July 21, 1998), (RADM, USN), was an American naval officer and aviator, test pilot, flag officer, one of the original NASA Mercury Seven astronauts, and businessman, who in 1961 became the second person and the first American to travel into space. This Mercury flight was designed to enter space, but not to achieve orbit. Ten years later, at age 47 and the oldest astronaut in the program, Shepard commanded the Apollo 14 mission, piloting the la -
John Glenn
On February 20, 1962, NASA launched one of the most important flights in American history. The mission? Send a man to orbit Earth, observe his reactions and return him home safely. The pilot of this historic flight, John Glenn, became a national hero and a symbol of American ambition. -
First space walk
In March 1965, at the age of 30, Soviet cosmonaut Alexei Leonov made the first spacewalk in history, beating out American rival Ed White on Gemini 4 by almost three months. -
Apollo1
Apollo 1 (initially designated AS-204) was the first manned mission of the U.S. Apollo manned lunar landing program.[1] The planned low Earth orbital test of the Apollo Command/Service Module never made its target launch date of February 21, 1967, because a cabin fire during a launch rehearsal test on January 27 at Cape Kennedy Air Force Station Launch Complex 34 killed all three crew members—Command Pilot Virgil I. "Gus" Grissom, Senior Pilot Edward H. White II, and Pilot Roger B. Chaffee—and d -
Apollo 11
On July 19, after Apollo 11 had flown behind the moon out of contact with Earth, came the first lunar orbit insertion maneuver. At about 75 hours, 50 minutes into the flight, a retrograde firing of the SPS for 357.5 seconds placed the spacecraft into an initial, elliptical-lunar orbit of 69 by 190 miles. Later, a second burn of the SPS for 17 seconds placed the docked vehicles into a lunar orbit of 62 by 70.5 miles, which was calculated to change the orbit of the CSM piloted by Collins. The chan -
Apollo 8
Apollo 8, the second human spaceflight mission in the United States Apollo space program, was launched on December 21, 1968, and became the first manned spacecraft to leave Earth orbit, reach the Earth's Moon, orbit it and return safely to Earth. The three-astronaut crew — Commander Frank Borman, Command Module Pilot James Lovell, and Lunar Module Pilot William Anders — became the first humans to travel beyond low Earth orbit, the first to see Earth as a whole planet, the first to directly see t -
Apollo 13
Apollo 13 was the seventh manned mission in the American Apollo space program and the third intended to land on the Moon -
Apollo 17
The lunar landing site was the Taurus-Littrow highlands and valley area. This site was picked for Apollo 17 as a location where rocks both older and younger than those previously returned from other Apollo missions, as well as from Luna 16 and 20 missions, might be found. -

Voyager 2
Voyager 2 is a space probe launched by NASA on August 20, 1977 to study the outer planets. Part of the Voyager program, it was launched 16 days before its twin, Voyager 1, on a trajectory that took -
First Space Shuttle launch
The first launch of the Space Shuttle occurred on 12 April 1981, exactly 20 years after the first manned space flight, when the orbiter Columbia, with two crew members, astronauts John W. Young, commander, and Robert L. Crippen, pilot, lifted off from Pad A, Launch Complex 39, at the Kennedy Space Center -
Sally Ride
Sally Ride and Valentina Tereshkova: Changing the Course of Human... ... On June 18, 1983, Sally Ride became the first American woman to fly in space when the space shuttle Challenger launched on mission STS-7. ... Marc Garneau became the first Canadian astronaut to fly to space. -
Challenger Disaster
The Space Shuttle Challenger disaster occurred on January 28, 1986, when the NASA Space Shuttle orbiter Challenger (OV-099) (mission STS-51-L) broke apart 73 seconds into its flight, leading to the deaths of its seven crew members, which included five NASA astronauts and two Payload Specialists. The spacecraft disintegrated over the Atlantic Ocean, off the coast of Cape Canaveral, Florida at 11:39 EST (16:39 UTC). Disintegration of the vehicle began after an O-ring seal in its right solid rocket -
Galileo launch
Galileo was an unmanned spacecraft that studied the planet Jupiter and its moons, as well as several other Solar System bodies. Named after the astronomer Galileo Galilei, it consisted of an orbiter and entry probe. -
Hubble Space
The Hubble Space Telescope is a space telescope that was launched into low Earth orbit in 1990, and remains in operation. With a 2.4-meter mirror, Hubble's four main instruments observe in the near ultraviolet, visible, and near infrared spectra -
First tourist
American businessman Dennis Tito, the world's first orbital space tourist, is seen training for his historic 2001 flight to the International Space Station. Tito launched in April 2001 aboard a Russian Soyuz spacecraft thanks to a $20 million deal brokered by the Virginia-based firm Space Adventures -
Colombia Disaster
The Space Shuttle Columbia disaster occurred on February 1, 2003, when Columbia disintegrated over Texas and Louisiana as it reentered Earth's atmosphere, killing all seven crew members. -
First launch of space ship one
It used the orbiter Atlantis and hardware originally processed for the STS-335 contingency mission, which was not flown. STS-135 launched on 8 July 2011, and landed on 21 July 2011, following a one-day mission extension. The four-person crew was the smallest of any shuttle mission since STS-6 in April 1983. -
New Horizon Launch
New Horizons is an interplanetary space probe that was launched as a part of NASA's New Frontiers program. Engineered by the Johns Hopkins University Applied Physics Laboratory and the Southwest Research Institute, with a team led by S. Alan Stern, The spacecraft was launched to study the Pluto system and, in its secondary mission, the Kuiper belt, performing a flyby of Pluto and one or more other Kuiper belt objects. -
New Horizions reaches Pluto
New Horizons launched on Jan. 19, 2006; it swung past Jupiter for a gravity boost and scientific studies in February 2007, and conducted a six-month-long reconnaissance flyby study of Pluto and its moons in summer 2015, culminating with Pluto closest approach on July 14, 2015. As part of an extended mission, pending NASA approval, the spacecraft is expected to head farther into the Kuiper Belt to examine another of the ancient, icy mini-worlds in that vast region, at least a billion miles beyond -
