Past Missions

Past missions hold some of our greatest achievements. After the Soviet Union's launch of Sputnik the United States quickly responded with their own satellite, Explorer. In 1958, NASA was founded and a series of great adventures began.

The highlight of past missions was, of course, the Apollo program, but without the vigorous tests done during previous programs, we might have never seen a man on the moon. These programs focused on the safety of the astronauts and the many techniques they would need to use in space.

Earth Missions

IMAGE: Explorer 1
Inaugurating the era of space exploration for the US, the First Explorer was launched into Earth orbit February 1, 1958 by the Army Ballistic Missle Agency.

Explorer 1

America's first artificial satellite.


Fast

FAST (Fast Auroral Snapshot Explorer), the second mission in NASA's Small Explorer Satellite Program (SMEX), is a satellite designed to study Earth's aurora.


Gravity Probe-B

Learn more about Gravity Probe-B on NASA's website.


Jason-1

Jason-1 is the first follow-on to the highly successful TOPEX/Poseidon mission that measured ocean surface topography to an accuracy of 4.2 cm, enabled scientists to forecast the 1997-1998 El Niño, and improved understanding of ocean circulation and its effect of global climate.


Polar

Human Spaceflight Missions

IMAGE: Apollo 13 Crew
Apollo 13 made a safe return to Earth after an oxygen tank explosion that kept the three-man crew from landing on the moon in April, 1970.
Apollo-Soyuz Test Project

The first space mission to be undertaken as a joint effort between the United States and the Soviet Union.


Apollo

President Kennedy's bold challenge set the nation on a journey unlike any before in human history--a journey to land on the moon.


Gemini

The bridge to the moon.


Hubble's Last Servicing Mission (SM4)

Space Shuttle Atlantis journeyed to the Hubble Space Telescope in 2009. The crew has completing 5 space walks.


Mercury

America's First Space Program.


Skylab

America's first space station and orbital science and engineering laboratory.

Solar System Missions

IMAGE: Galileo Arrives at Jupiter
Galileo was an unmanned spacecraft sent by NASA to study the planet Jupiter and its moons.

Deep Impact

Exploring Comet Tempel 1 to determine the origins of life in our Solar System.


Galileo

Journey to Jupiter.


IMAGE

IMAGE was a mission to study the global response of the magnetosphere to the changes in solar wind.


Lunar Crater Observation and Sensing Satellite (LCROSS)

A mission to confirm the presence of water ice in a permanently shadowed crater near the south pole of the Moon.

Learn more about LCROSS on NASA's website.


Magellan

Magellan spacecraft made a dramatic conclusion to its highly successful mission at Venus when it is commanded to plunge into the planet's dense atmosphere.


Mars Global Surveyor

Mars Global Surveyor was the first successful U.S. mission launched to Mars since the Viking mission in 1976.


Mars Pathfinder

Mars Pathfinder was the first mission to deliver a lander and a free-ranging robotic rover to the surface of Mars.

Learn more about Mars Pathfinder on NASA's website.


NEAR

NEAR (Near Earth Asteroid Rendezvous) is the first mission ever to go into orbit around an asteroid.


Phoenix Mars Lander

The Phoenix Mars Lander surpassed its 3 month mission in the Northern Plains of Mars by 2 months.


Pioneer

A journey through our solar system and beyond.


Ranger

The Ranger series was the first U.S. attempt to obtain close-up images of the Lunar surface.


SAMPEX

Learn more about SAMPEX on NASA's website.


Stardust

First NASA mission to return particles from beyond the Earth Moon orbit.


Surveyor

The Surveyor probes were the first U.S. spacecraft to land safely on the Moon.


TRACE


Ulysses

A mission to study the Sun at all latitudes.


Voyager

The interplanetary mission to explore Jupiter, Saturn, Uranus, and Neptune.

Beyond the Solar System Missions

COBE

The COBE (Cosmic Background Explorer) satellite was to measure the diffuse infrared and microwave radiation from the early universe to the limits set by our astrophysical environment.


Compton Gamma Ray Observatory

The Compton Gamma Ray Observatory was the second of NASA's Great Observatories.


FUSE

FUSE (Far Ultraviolet Spectroscopic Explorer) was launched explore the Universe using the technique of high-resolution spectroscopy in the far-ultraviolet spectral region.


Genesis

The search for orgins.


SAMPEX

SAMPEX studies the energy, composition and charge states of particles from supernova explosions in the distant reaches of the galaxy, from the heart of solar flares and from the depths of nearby interstellar space.


WISE
