NASA’s MAVEN spacecraft recently completed assembly and has started environmental testing. In the Multipurpose Test Facility clean room at Lockheed Martin, technicians installed the orbiter’s two solar arrays prior to a modal test.(Courtesy Lockheed Martin). N... More »
This artist’s concept shows the Euclid spacecraft. The telescope will launch to an orbit around the sun-Earth Lagrange point L2. The Lagrange point is a location where the gravitational pull of two large masses, the sun and Earth in this case, precisely equals... More »
Variations in total water storage from normal, in millimeters, in the Tigris and Euphrates river basins, as measured by NASA’s Gravity Recovery and Climate Experiment (GRACE) satellites, from January 2003 through December 2009. Reds represent drier conditions,... More »
A shiny-looking Martian rock is visible in this image taken by NASA’s Mars rover Curiosity’s Mast Camera (Mastcam) during the mission’s 173rd Martian day, or sol (Jan. 30, 2013). Image Credit: NASA/JPL-Caltech/Malin Space Science Systems On Mars, as on Earth, ... More »
At the center of this image from NASA’s Curiosity rover is the hole in a rock called “John Klein” where the rover conducted its first sample drilling on Mars. The drilling took place on Feb. 8, 2013, or Sol 182, Curiosity’s 182nd Martian day of operations. Sev... More »
In an activity called the “mini drill test,” NASA’s Mars rover Curiosity used its drill to generate this ring of powdered rock for inspection in advance of the rover’s first full drilling. Image credit: NASA/JPL-Caltech/MSSS The drill on NASA’s Mars rover Cu... More »
This is an artist’s impression of two young binary stars that may be the source of mysterious clock-like bursts of light from an object called LRLL 54361 that lies inside the star-forming region IC 348, located 950 light-years away. Image credit: NASA/ESA/JPL-... More »

The latest image of sea surface heights in the Pacific Ocean from NASA’s Jason-1 satellite shows that the equatorial Pacific Ocean is now in its 10th month of being locked in what some call a neutral, or “La Nada” state. “La Nadas” make long-range climate fore... More »
Astronomers estimate that six percent of red dwarfs have a temperate Earth-size planet, as close as 13 light-years away. Image credit: D. Aguilar/Harvard-Smithsonian Center for Astrophysics Using publicly available data from NASA’s Kepler space telescope, as... More »
This is the orbital trajectory of comet C/2012 S1 (ISON). The comet is currently located just inside the orbit of Jupiter. In November 2013, ISON will pass less than 1.1 million miles (1.8 million kilometers) from the sun’s surface. The fierce heating it exper... More »
The Orion nebula is featured in this sweeping image from NASA’s Wide-field Infrared Survey Explorer, or WISE. The constellation of Orion is prominent in the evening sky throughout the world from about December through April of each year. The nebula (also catal... More »
