Researchers have discovered on the Red Planet the largest fresh meteor-impact crater ever firmly documented with before-and-after images. The images were captured by NASA’s Mars Reconnaissance Orbiter. The crater spans […]
Scientists working with data from NASA’s Cassini mission have developed a new way to understand the atmospheres of exoplanets by using Saturn’s smog-enshrouded moon Titan as a stand-in. The new […]
Scientists combined observations from two NASA missions to check out the moon’s lopsided shape and how it changes under Earth’s sway – a response not seen from orbit before. The […]
Jupiter’s trademark Great Red Spot — a swirling storm feature larger than Earth — is shrinking. This downsizing, which is changing the shape of the spot from an oval into […]
NASA’s Curiosity Mars rover used several tools to examine the candidate site over the weekend, including a wire-bristle brush — the Dust Removal Tool — to clear away dust from […]
NASA has issued a Request for Information (RFI) to science and engineering communities for ideas for a mission to Europa that could address fundamental questions of the enigmatic moon and […]
A new image from NASA’s Curiosity Mars rover is the first ever from the surface of Mars to show an asteroid, and it shows two: Ceres and Vesta. These two […]
On April 20, MESSENGER completed its 3,000th orbit of Mercury and moved closer to the planet than any spacecraft has been before, dropping to an altitude of 199 kilometers (123.7 […]
Ground controllers at NASA’s Ames Research Center in Moffett Field, Calif., have confirmed that NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft impacted the surface of the moon, as […]
Using NASA’s Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the “habitable zone” — the range of distance from a star where liquid water […]
NASA’s Cassini spacecraft has documented the formation of a small icy object within the rings of Saturn that may be a new moon, and may also provide clues to the […]
In its sixth Martian winter, NASA’s Mars Exploration Rover Opportunity now has cleaner solar arrays than in any Martian winter since its first on the Red Planet, in 2005. Cleaning […]
Scientists using NASA’s Curiosity Mars rover are eyeing a rock layer surrounding the base of a small butte, called “Mount Remarkable,” as a target for investigating with tools on the […]
Images taken by NASA’s Curiosity Mars rover on April 2 and April 3 include bright spots, which might be due to the Sun glinting off a rock or cosmic rays […]
NASA’s team that will conduct the first U.S. mission to collect samples from an asteroid has been given the go-ahead to begin building the spacecraft, flight instruments and ground system, […]
As NASA’s Cassini mission approaches its 10th anniversary at Saturn, its team members back here on Earth are already looking ahead to an upcoming phase. Starting in late 2016, the […]
Late afternoon lighting produced a dramatic shadow of NASA’s Mars Exploration Rover Opportunity photographed by the rover’s rear hazard-avoidance camera on March 20, 2014. The shadow falls across a slope […]
Some 60 scientists and engineers came together March 26-28, 2014, for the first ExoMars 2018 Landing Site Selection Workshop, held at ESA’s European Space Astronomy Centre near Madrid. Their task […]
On Wednesday, NASA’s Curiosity Mars rover drove the last 98 feet feet (30 meters) needed to arrive at a site planned since early 2013 as a destination for studying rock […]
