Gemini Program Launched (1963 - 1965)
Gemini program initiated to develop space travel techniques in support of the Apollo missions. The program ran between 1963 and 1966 and resulted in ten manned flights.
April 8, 1964
First test flight of the Gemini program. It did not have humal life support systems. Although it featured a heat shield, the shield had four large holes drilled in it to make sure that the spacecraft was destroyed during reentry. In place of the crew couches were measuring equipment that relayed telemetry measuring the pressure, vibration, acceleration, temperature, and structural loads during the short flight.
January 19, 1965
Gemini II suborbital flight to test heat shield. Shortly after launch the Mission Control Center suffered a power outage. Control of the mission was transferred to a tracking ship. The outage was later traced to an overload of the electrical system from the network television equipment used to cover the launch.

January 27, 1967
Mission AS-204 is struck by tragedy when a flash fire breaks out during a launch pad test, killing three astronauts: Virgil Grissom, who had participated in Mercury and Gemini flights; Edward White, who conducted NASA's first extravehicular activity; and new astronaut Roger Chaffee. The mission, one of NASA's first major setbacks, was later renamed Apollo 1.

April 11, 1970
Apollo 13 was launched. The lunar landing was aborted after an oxygen tank exploded two days later. Despite enormous problems caused by limited power, loss of cabin heat, shortage of potable water and the critical need to jerry-rig the carbon dioxide removal system, the crew returned safely to Earth on April 17. Commanded by James Lovell and also manned by John Swigert and Fred Haise.

The Launch of unmanned Pioneer 10 provided a bunch of firsts for the space program. Pioneer 10 and Pioneer 11 were robotic space probes. Pioneer 10 was launched in 1972 and its mission was to send back data and images of Jupiter. It was the first spacecraft to fly through the asteroid belt, fly to Jupiter and make close-up observations, Saturn, the Milky Way Galaxy and reach escape velocity to leave our Solar System. Pioneer 10 sent its last communication back to Earth on January 22, 2003, while 7.6 billion miles from home.
December 7, 1972

August 20, 1975
Launch of Viking 1, the first orbiter and lander sent to Mars. Viking 2 would launch a few weeks later. Both landed safely on Mars and for six years sent back the first set of images and data from the Martian surface.
August 12, 1977
ALT-12 - First free flight of the Space Shuttle. Enterprise was built for NASA as part of the Space Shuttle program to perform test flights in the atmosphere. It was constructed without engines or a functional heat shield, and was therefore not capable of spaceflight. It was originally planned to be named Constitution. A campaign by fans of the television show 'Star Trek' to President Gerald Ford asked that the orbiter be named after the Starship Enterprise, featured on the television show. Although Ford did not mention the campaign, the president said that he was "partial to the name" and overrode NASA officials.

August 20, 1977
Launch of Voyager 2, one of a pair of spacecraft sent by NASA on what was supposed to be a five-year mission to study Jupiter and Saturn. Voyagers 1 and 2 continue to send back pictures and data today, 30 years later from nearly 10 billion miles away.
September 5, 1977
Launch of Voyager 1. Voyager 1 would later return some incredible images from its encounter with Jupiter and Saturn.

January 28, 1986
STS-51-L - First major catastrophe for NASA, when space shuttle Challenger exploded 73 seconds after takeoff with seven crew members aboard. Total loss of vehicle and crew, including a civilian teacher. It was later determined that the failure was caused by the failure of an O-ring seal on the Solid Rocket Boosters. 73 seconds after lift-off, the vehicle experienced a catastrophic structural failure and the orbiter rapidly broke up. The launch had been approved despite a predicted ambient temperature of 26 °F (−3 °C), well below the qualification limit of major components. It is almost certain the actual disintegration did not kill the entire crew as 3 of the 4 PEAPs (personal egress air packs) that were recovered had been manually activated.

Mir space station launches.
September 29, 1988
STS-26 - Space Shuttle flights resume when Discovery is launced from Kennedy Space Center. It was declared the "Return to Flight" mission. The primary payload was a Tracking and Data Relay Satellite (TDRS). Eleven scheduled mid-deck scientific and technological experiments were carried out. The orbiter sustained only minor Thermal Protection System tile damage, and the redesigned post-Challenger solid rocket boosters showed no signs of leakage or overheating at any of the joints.
October 18, 1989
STS-34 - Space shuttle Atlantis launches Galileo to study Jupiter and its moons. It took Galileo six years to reach Jupiter, and it finally disintegrated in Jupiter's atmosphere in September of 2003, 14 years after it began its collision course toward the giant planet.

STS-61 - This was the first Hubble Space Telescope servicing mission. The mission restored the spaceborne observatory's vision with the installation of a corrective optics package and also installed instrument upgrades. The STS-61 mission was one of the most complex in the Shuttle's history. It lasted almost 11 days, and crew members made five spacewalks, an all-time record.

July 22-27, 1999
STS-93 - First woman to command a Shuttle mission. Columbia's 26th flight was led by Air Force Col. Eileen Collins. Five seconds after launch an electrical short disabled the primary controller on two of the three main engines and they automatically switched to backup controllers. The problem was later discovered to have been caused by poorly routed wiring which had rubbed on an exposed screw head. Premature engine shutdown resulted in a slightly lower orbit.
August 8, 2001
Launch of Genesis, which would collect samples of atoms from solar wind which is ejected from the outer portion of the sun, and return it to Earth. Genesis would be the first attempt to return samples to Earth since the Apollo moon mission in 1972. Upon return to Earth it crash-landed in Utah on September 8, 2004, after a design flaw prevented the deployment of its parachute. Most of the samples were damaged but some were successfully recovered.

STS-107 - Crew of seven astronauts, including the first Israeli astronaut, is lost after a 16-day mission when the Columbia space shuttle explodes on re-entry. The accident was later attributed to damage sustained to foam insulation and has led NASA to understand how to safely repair similar damage on later missions.

STS-114 - Space Shuttle Discovery launched successfully into orbit, marking NASA's first return to human spaceflight after the Columbia tragedy. The problem that caused the loss of Columbia – debris separating from the external tank during ascent – unexpectedly recurred during the launch of Discovery. As a result, NASA decided to postpone future shuttle flights pending modifications.
