Welcome to the NASA Space Science Data Coordinated Archive, NASA's archive for space science mission data.

ESA's Gaia mission launched successfully on a Soyuz-Fregat rocket from Kourour, French Guiana at 09:12UT on 19December 2013. The mission is designed to measure the positions and velocity of roughly 1,000,000,000 stars as well as determine their temperature, composition, and other properties. More...

NASA's Wide-field Infrared Survey Explorer(WISE) satellite has released data from the first 57% of the sky surveyed during the mission. The satellite went into hibernation in early February2011, but its discoveries include 20 comets, more than 33,000 asteroids between Mars and Jupiter, and 133 near-Earth objects. More...

NASA's launch of the Interface Region Imaging Spectrograph (IRIS) spacecraft took place at 7:27p.m. on 27June 2013 (02:27UT, 28June) about 100miles from Vandenberg AFB. More...

Voyager 1 has encountered a region of spacecraft at the edge of our solar system that scientists believe is the last region the spacecraft will have to cross prior to entering interstellar space. More...

Five investigations have been selected as finalists for the next Discovery class missions. One or two will be chosen to fly as early as 2020. The finalists include two Venus missions, two asteroid missions, and an NEO mission. More...

Comet 67P/Churyumov-Gerasimenko reached perihelion at 02:03UT on 13August 2015. The Rosetta spacecraft, flying with the comet, has observed increased activity. It is hoped that the Philae lander will be able to observe changes at the surface as well. More...

Images and data from Pluto and its moons continue to trickle in from the New Horizons spacecraft. Images of atmospheric haze and evidence of flowing ice were discussed at a press conference on 24July. For recent images and information, see the NASA and APL New Horizons pages.
