NASA's Mars Reconnaissance Orbiter has observed a new category of minerals spread across large regions of Mars.
Phoenix has finished scooping soil samples to deliver to its onboard laboratories, and is now preparing to analyze samples already obtained.
Phoenix successfully delivered soil into oven six of the lander's thermal and evolved-gas analyzer on Monday, Oct. 13.
NASA's Phoenix Mars Mission is being honored with a Breakthrough Award by Popular Mechanics magazine today in New York City.
The Phoenix Lander over the weekend successfully weathered a regional dust storm that temporarily lowered its solar power, and the team is ack investigating the Red Planet's northern plains.
High winds and dust devils blew through Phoenix's landing site last weekend. These two short videos show them in action.
NASA's Phoenix Mars Lander has been digging and excavating Martian soil with its nearly 8-foot-long robotic arm. New images, like this one in 3D, show the trenchwork taken on Oct. 7.
As fall approaches Mars' northern plains, NASA's Phoenix Lander is busy digging into the Red Planet's soil and scooping it into its onboard science laboratories for analysis.
The longest-serving of six spacecraft now studying Mars is up to new tricks for a third two-year extension of its mission to examine the most Earthlike of known foreign planets.
NASA's Phoenix Mars Lander has detected snow falling from Martian clouds. Spacecraft soil experiments also have provided evidence of past interaction between minerals and liquid water, processes that occur on Earth.
NASA's Mars Reconnaissance Orbiter has revealed hundreds of small fractures exposed on the Martian surface that billions of years ago directed flows of water through underground Martian sandstone.
NASA's Phoenix Mars Lander slid a rock into a nearby trench Monday to gain access to the soil under the rock.
If the robotic arm on NASA's Phoenix Mars Lander can nudge a rock aside today, scientists on the Phoenix team would like to see what's underneath.
NASA's Mars Rover Opportunity is setting its sights on a crater more than 20 times larger than its home for the past two years.
A new color high-resolution image from the Phoenix Mars Lander shows its crumpled heat shield about 150 meters away from the spacecraft.
NASA's Phoenix Mars Lander has successfully delivered more soil to its Wet Chemistry Laboratory.
Phoenix has photographed several dust devils dancing across the arctic plain this week and sensed a dip in air pressure as one passed near the lander.
Scientists are analyzing results from soil samples delivered several weeks ago to science instruments on NASA's Phoenix Mars Lander to understand the landing site's soil chemistry and mineralogy..
The next soil sample that Phoenix will deliver to its deck instruments will go to the fourth of the four cells of Phoenix's wet chemistry laboratory, according to the Phoenix team's current plans.
A fork-like conductivity probe has sensed humidity rising and falling beside Phoenix, but when stuck into the ground, its measurements so far indicate soil that is thoroughly and perplexingly dry.
