structure and evolution of the universe.
mission is an in-situ investigation of the Earth's magnetosphere using four
identical spacecraft simultaneously.

a NASA Discovery Program mission that would place a single geophysical lander on Mars to study its deep interior.
International Gamma-Ray Astrophysics Laboratory (INTEGRAL)
launched on October 17, 2002. It was lifted off from Baikonur in Kazakhstan on a Russian Proton launcher and is now
on a 72-hour elliptical orbit, ranging from 9,000 km up to 155,000 km from Earth. It will produce a complete map of
the sky in the soft gamma-ray waveband and it is capable of performing high spectral and spatial observations
in gamma rays.
is the fourth mission in U.S.-European series of satellite missions
that measure the height of the ocean surface.
improve our understanding of the solar system's beginnings by revealing the origin and evolution of Jupiter.
is specifically designed to survey a portion of our region of the Milky
Way galaxy to discover dozens of Earth-size planets in or near the habitable zone and determine how many of the billions
of stars in our galaxy have such planets.
Lunar Reconnaissance Orbiter (LRO)
returns to the moon, enabling new
discoveries and bringing the moon back into the public eye.
Mars Atmosphere and volatile EvolutioN (MAVEN)
is part of NASA's Mars
Scout program, funded by NASA Headquarters. Set to launch in 2013, the mission will explore the Red
Planet's upper atmosphere, ionosphere and interactions with the sun and solar wind.
Mars Exploration Rovers (MER)
is part of NASA's Mars
Exploration Program, a long-term effort of robotic exploration of the red planet.
MEcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER)
is the first spacecraft to orbit Mercury, MESSENGER followed a path through the inner solar system, including
one flyby of Earth, two flybys of Venus, and three flybys of Mercury.
Mars Express (MEX)
will image the entire surface of Mars at high resolution (10 meters/pixel)
and selected areas at super resolution (2 meters/pixel).
Mars Reconnaissance (MRO)
blasted off from Cape Canaveral in 2005,
on a search for evidence that water persisted on the surface of Mars for a long period of time.
Mars Science Laboratory (MSL)
is a rover that will assess whether Mars ever
was, or is still today, an environment able to support microbial life.
began its journey across the solar system to conduct flyby
studies of Pluto and its moon.
2001 Mars Odyssey
is part of NASA's Mars Exploration
Program, a long-term effort of robotic exploration of the red planet.
Asteroid Sample Return Mission OSIRIS-REx
is the third planetary science
mission selected for development in NASA's New Frontiers Program.
Venus Climate Oribter (PLANET-C) - JAXA
is one of the future planetary
missions of Japan, aims at understanding the atmospheric circulation of Venus.
orbiter will rendezvous with Comet 67P/Churyumov-Gerasimenko and
remain in close proximity to the icy nucleus as it plunges towards the warmer inner reaches of the Sun's domain.
At the same time, a small lander will be released onto the surface of this mysterious cosmic iceberg.
Soil Moisture Active Passive (SMAP)
will provide global measurements of soil moisture
and its freeze/thaw state.
Solar & Heliospheric Observatory (SOHO)
project is a cooperative effort between the European Space Agency (ESA) and NASA. SOHO was designed to study the internal
structure of the Sun, its extensive outer atmosphere and the origin of the solar wind, the stream of highly ionized gas
that blows continuously outward through the Solar System.
Solar Probe Plus
will be an extraordinary and historic mission, exploring what is arguably the last region of the solar system to be visited
by a spacecraft, the Sun's outer atmosphere or corona as it extends out into space.
SPITZER Space Telescope
is drifting in a unique Earth-trailing orbit around the Sun,
Spitzer sees an optically invisible universe dominated by dust and stars.
Solar TErrestrial RElations Observatory (STEREO)
is the third mission in NASA's Solar Terrestrial Probes program (STP).
twin spacecraft continue exploring where nothing from Earth has flown before. In the 34th year after their 1977 launches, they
each are much farther away from Earth and the Sun than Pluto.
Venus Express (VEX)
studies the complex dynamics and chemistry, and
the interactions between the atmosphere and the surface, which will give clues about the surface characteristics of Venus.
was launched on November 1, 1994 and is the first of two NASA spacecraft in the Global Geospace Science initiative and part of
the ISTP Project.
