Researchers using NASA’s Mars Reconnaissance Orbiter have found that temperatures in the Martian atmosphere regularly rise and fall not just once each day, but twice.
“We see a temperature maximum in the middle of the day, but we also see a temperature maximum a little after midnight,” said Armin Kleinboehl of NASA’s Jet Propulsion Laboratory in Pasadena, Calif., who is … Read the rest of this article
This mosaic, which features the spectacular Kasei Valles, comprises 67 images taken with the High Resolution Stereo Camera on ESA’s Mars Express. The mosaic spans 987 km north–south (19–36°N) and 1550 km east–west (280–310°E). Image Credit:ESA/DLR/FU Berlin (G. Neukum)
Dramatic flood events carved this impressive channel system on Mars covering 1.55 million square kilometres, shown here in a stunning new … Read the rest of this article
This set of artist’s concepts shows NASA’s Mars Science Laboratory cruise capsule and NASA’s Orion spacecraft, which is being built now at NASA’s Johnson Space Center and will one day send astronauts to Mars. The rover Curiosity is tucked inside of the Mars Science Laboratory cruise vehicle like human beings would be tucked inside Orion. Image credit: NASA/JPL-Caltech/JSC

NASA’s Kepler mission has discovered two new planetary systems that include three super-Earth-size planets in the “habitable zone,” the range of distance from a star where the surface temperature of an orbiting planet might be suitable for liquid water.

The artist’s concept depicts Kepler-62f, a super-Earth-size planet in the habitable zone of a star smaller and cooler than the sun, …
Hardware from a spacecraft that the Soviet Union landed on Mars in 1971 might appear in images from NASA’s Mars Reconnaissance Orbiter.
While following news about Mars and NASA’s Curiosity rover, Russian citizen enthusiasts found four features in a five-year-old image from Mars Reconnaissance Orbiter that resemble four pieces of hardware from the Soviet Mars 3 mission: the parachute, heat … Read the rest of this article
Over the years, the spacefaring nations of Earth have sent dozens of probes and rovers to explore Mars. Today there are three active satellites circling the red planet while two rovers, Opportunity and Curiosity, wheel across the red sands below. Mars is dry, barren, and apparently lifeless.
Soon, those assets could find themselves exploring a very different kind of world.… Read the rest of this article
ESA’s Mars Express has spent nearly ten years imaging the Red Planet, and there are plenty of hidden treasures buried in the mission’s rich picture archive.

This mosaic shows part of the Noctis Labyrinthus region, the ‘Labyrinth of the Night’, on Mars. It was composed by Bill Dunford using scenes available in the Mars Express image archive, HRSCview. This image …
An analysis of a rock sample collected by NASA’s Curiosity rover shows ancient Mars could have supported living microbes.
Scientists identified sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon — some of the key chemical ingredients for life — in the powder Curiosity drilled out of a sedimentary rock near an ancient stream bed in Gale Crater on the Red Planet … Read the rest of this article
NASA has recently discovered a very strange planet. Its days are twice as long as its years. It has a tail like a comet. It is hot enough to melt lead, yet capped by deposits of ice. And to top it all off … it appears to be pink.
The planet is Mercury.
Of course, astronomers have known about Mercury … Read the rest of this article

This view of layered rocks on the floor of McLaughlin Crater shows sedimentary rocks that contain spectroscopic evidence for minerals formed through interaction with water. The High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter recorded the image. A combination of clues suggests this 1.4-mile-deep (2.2-kilometer-deep) crater once held a lake fed by groundwater. Part of the …
