Pioneer 5 
  March 1960 
The first study of the magnetic field between the planets was conducted by Pioneer 5.
Vostok I 
  April 12, 1961

Mercury 
  May 1961 
Alan Shepherd was America's first man in space. The one-man spacecraft went outside Earth's atmosphere but did not go into orbit.
Vostok 2 
  August 1961 
The Soviets made another manned flight which lasted a day and orbited the Earth 17 times.
Mercury 
  February 1962 
The first American to orbit the Earth was John Glenn, who orbited the planet three times in a Mercury one-man spacecraft.
Mariner 2 
  August 1962 
This was the first spacecraft to perform a flyby of another planet, in this case Venus. It found that the surface of Venus was just as hot as that of Mercury, and that the atmosphere is 100 times heavier than Earth's atmosphere.
Vostok 6 
  June 1963 
Valentina Tereshkova became the first woman in space. She orbited the Earth 48 times in Vostok 6.
Mariner 4

Pioneer 6-9 
  between December 1965-November 1968 
These crafts measured properties of the solar wind and the sun's magnetic field.
Mariner 5 
  June 1967 
This Mariner mission was designed to study Venus' atmosphere using radio waves.
Apollo 7 
  October 1968 
The Apollo spacecraft orbited the Earth in order to test the command module.
Apollo 8 
  December 1968 
The first manned mission to the Moon successfully orbited for a day and then returned to Earth.
Mariner 6 & 7 
  February and March 1969 
These two spacecraft were designed to work together to provide a more detailed view of Mars' surface. It showed an abundance of channels on the surface, which might have been carved by water, and a number of volcanoes, valleys, and canyons.
Apollo 9 
  March 1969 
In order to test the lunar landers that would take astronauts to the surface of the Moon, the Apollo 9 spacecraft performed a dry run in an Earth orbit.
Apollo 10 
  May 1969 
This mission was an unmanned dress rehearsal for bringing the first astronauts to the Moon. The lunar lander was flown close to the Moon's surface (50,000 feet away), but did not actually land.
Apollo 11 
  July 20, 1969 
The first men, Neil Armstrong and Buzz Aldrin, reached the moon. As Armstrong stepped out onto the Sea of Tranquility, he said, "That's one small step for a man, one giant leap for mankind." They spent only two hours on the surface collecting moon rocks, and then returned in the lunar lander to the orbiting Apollo spacecraft.
Apollo 12 
  November 19, 1969 
Charles Conrad and Alan Bean walked on the Moon.
pollo 13 
  April 1970 
This Apollo mission did not make it to the Moon, because an oxygen tank burst. It is considered one of NASA's finest achievements, however, since so many obstacles were overcome in bringing the astronauts safely back to Earth.
Venera 1-10 
  1970-1982 
These Soviet spacecraft landed on the surface of Venus. Because of the intense conditions at the surface, they only worked for a few minutes, but four of the missions sent back photographs of the surface, which was covered with lava rocks.
Apollo 14 
  February 5, 1971 
Alan Shepard and Edgar Mitchell walked on the Moon.
Mariner 9 
  May 1971 
This was the first spacecraft to actually orbit the planet Mars. The surface was again photographed and the atmosphere was analyzed extensively. Apollo 15 
Pioneer 10 
  March 1972 
The first flyby of Jupiter was done in 1973. The atmosphere and magnetic field were studied. Pioneer 10 continued to communicate with Earth on its way out of the solar system, and in January 2003, its last signal was recorded. As of July 2003, Pioneer 10 is 7.83 billion miles from the Earth, and it is traveling at a speed of 27,317 miles per hour.
Apollo 16 
  April 20, 1972 
John Young and Charles Duke walked on the Moon.
Apollo 17 
  December 11, 1972 
Eugene Cernan and Harrison Schmitt walked on the Moon. Schmitt was the first scientist chosen to be an astronaut (he was a geologist).
Pioneer 11 
  April 1973 
This probe followed Pioneer 10 in a trip to Jupiter, and then went on to Saturn. Its mission ended in November 1995, when the last communication was received. If Pioneer 11 survives long enough, in 4 million years it will pass near one of the stars in the constellation Aquila.
Mariner 10 
  November 1973 
This is the only American spacecraft sent to Mercury. It flew by the planet three times to take pictures, which showed that Mercury has an iron core and a moon-like surface that is constantly pelted by solar system objects. The probe reached Mercury with the help of the gravitational influence of Venus. It was the first mission to use this gravity assist trajectory, and had the benefit of studying both planets.
Apollo-Soyuz Test Project 
  July 1975 
This was the first collaboration between the space programs of the United States and the Soviet Union. Rendezvous and docking procedures were tested when spacecraft were  separately from each country and then met in space.
Viking 1 & 2 
  August and September 1975 
The purpose of these two missions was to search for signs of life on Mars. They found no signs of life in either the past or the present, but took many photographs in order to map the surface of Mars.
Voyager 2 
  August 1977 
Voyager 2 also did in-depth studies of Jupiter and its moons, and found a thin ring around the planet. Its study of Saturn helped map the atmosphere's quick-moving clouds. It then went on to the outer planets of the solar system. It arrived at Uranus in 1986, and sent back photos of a planet which appeared blue because of its methane atmosphere. The interesting moons of Uranus were also photographed. In 1989, it reached Neptune, and found that this planet has an active atmosphere. Also of interest was the fact that Neptune's moon Triton has a thin atmosphere. After this grand tour, Voyager 2 headed out of the solar system.
Voyager 1 
  September 1977 
Voyager 1 was a sophisticated probe which did a flyby of Jupiter and many of its moons. It found that the moon Io is the most volcanically active body in the solar system. Then it headed to Saturn to study its ring system and moons. It then started on a path out of the solar system. It is now almost 8 billion miles from the Earth, making it the most distant human-made object, and is at the edge of the solar system.
Pioneer Venus 
  May 1978 
This American craft mapped Venus' volcanic surface until 1992
Space Shuttles 
 first flight April 1981 
The space shuttles were designed as a new type of spacecraft that could withstand re-entry into the Earth's atmosphere and subsequently be used again for later missions. There have been five space shuttles: Columbia, Discovery, Endeavor, Atlantis, and Challenger. The first American woman in space, Sally Ride, lifted off in June 1983. The Challenger exploded during launch on January 28, 1986, killing all seven crew members. The shuttle program was then grounded for more than two years while safety issues were reviewed. On ... the Columbia exploded during reentry, also killing all seven astronauts. It has been determined that a piece of foam hit the wing during launch, causing an unstable condition for re-entering the atmosphere. Aside from these tragedies, the space shuttle program has been very successful, having completed more than 65 missions and acting as both a transport device and a scientific laboratory.
Venera 15&16 
  1983 
These two Soviet crafts mapped Venus' surface.
Mir Space Station 
  February 1986 
This was the first space station, designed to hold a human crew in orbit of the Earth for extended periods of time. Mir was in service for more than 10 years, during which time many NASA astronauts had the chance to practice living in space.
Magellan 
  May 1989 
Venus' landscape and its magnetic field were studied by this craft, along with the distribution of mass within the planet. It provided the first comprehensive look at the geology of Venus.
Galileo 
  October 1989 
In 1995, Galileo arrived at Jupiter and shot a probe into the atmosphere. It spent several years doing a survey of the planet and several of its moons. Europa was found to be particularly interesting, with an ocean under a crust of ice. The volcanic moon Io was also studied.
Hubble Space Telescope 
  April 1990 
The HST has proven to be the most successful telescope ever built. Although some ground-based telescopes are larger, they have the disadvantage of peering through the atmosphere of the Earth. Hubble, on the other hand, is in orbit 380 miles above Earth, so it does not encounter any atmospheric disturbances. It has taken photographs of close objects such as the Moon and planets as well as images of the most distant astronomical objects ever viewed by humans. When Hubble was first , there was a small aberration in the telescope's mirror. In 1993, a team of astronauts rendezvoused with Hubble and were able to fix the problem. The photos Hubble has taken since this servicing mission are unparalleled in quality, and have literally changed the face of astronomy. HST has now viewed almost 20,000 objects and taken more than 350,000 pictures!
Ulysses 
  October 1990 
This is a joint U.S. and European solar observatory that passes the poles of the Sun every five years. It gives a view of the Sun not available from Earth.
SOHO 
  December 1995 
The Solar and Heliospheric Observatory is a joint U.S. and European mission. It is studying the internal structure of the Sun, its outer atmosphere, and the origin of the solar wind. It has been giving astronomers an uninterrupted view of the Sun, and hopefully will provide information on the affect of the Sun on Earth's environment.
Near-Earth Asteroid Rendezvous (NEAR) 
  February 1996 
This probe entered the asteroid belt between Mars and Jupiter and concentrated on the asteroids Mathilde and Eros.
Mars Global Surveyor 
  November 1996 
This probe has been orbiting Mars since 1997, sending back hundreds of photographs to make the most detailed map of the surface. Scientifically, the surveyor has hinted that Mars may be a more hospitable environment to life than was previously imagined: it is wet, volcanic, and geologically younger than was previously believed.
Mars Pathfinder 
  December 1996 
This unique mission was a landmark for NASA, because it was designed innovatively to cut costs in a program whose budgets are constantly being squeezed. Once in orbit around Mars, the lander separated from the orbiter, and a parachute opened in order to slow the descent. A system of heavy-duty airbags inflated around the lander, and it bounced along the surface in a rocky valley. The airbags deflated, and the lander opened like a flower. A special rover named Sojourner was then able to leave the lander and explore the local surface. Sojourner was able to take photographs and geologically test the rocks and dust, which greatly improved scientists' understanding of the red planet. In addition, the whole scene was broadcast live on television and the internet, making it a very popular mission with the general public.
Cassini 
  October 1997 
In 2004, Cassini will rendezvous with Saturn in a mission which is similar to the Galileo mission of Jupiter. It will land on Saturn's biggest moon, Titan, to study the possibility of life evolving on this moon. Scientists believe that the relatively harsh environment on Titan is similar to the environment on Earth when life first formed.
International Space Station 
 building started in 1998 
The first extensive cooperation between space agencies from different countries started in 1993, when the US, Russia, and other European countries decided to pool their resources to build an international station in space. Human crews are living aboard the space station for extended periods of time, which has allowed scientists to study the reaction of the body to living in a zero-gravity environment. Hundreds of microgravity scientific experiments which are not possible on Earth have been conducted by the astronauts. Experiments have been done in the fields of physics, geology, medicine, and technology.
Chandra X-ray Observatory 
  July 1999 
This observatory is in orbit around the Earth. Its goal is to study high-energy regions of space containing exotic objects such as black holes and the remnants of supernovae. It has already discovered a new type of black hole, and has recorded x-rays coming from comets. It can observe X-rays from particles during the last second before they fall into a black hole. Chandra flies 200 times higher above the Earth than does the Hubble Space Telescope.
CESat / CHIPSat 
  January 2003 
The ICESat satellite is studying the global sea level and the condition of the polar ice sheets, while the CHIPSat satellite is characterizing the properties of the hot gas in the interstellar medium, in order to better understand how stars form.
SORCE 
  January 2003 
This satellite is measuring incoming radiation from the Sun in order to determine its effect on Earth's atmosphere and climate. It is studying x-ray, ultraviolet, visible, and infrared radiation.
GALEX 
  April 2003 
The GALEX satellite will observe a million galaxies up to 10 billion years old in order to determine when and how the first galaxies originated.
Mars Exploration Rover Opportunity 
  July 2003 
This robotic explorer will land on Mars and study the rocks and soil in order to get a better idea of the past existence of water on Mars.
Space Infrared Telescope Facility 
 launch date August 2003 
The SIRTF is a successor to the Hubble Space Telescope. It is an infrared telescope that will study the most distant and coldest objects in the universe
