Snowboarding Dry Ice On Martian Dunes
2013-06-12 08:58:14

[ Watch the Video: Dry Ice Moves on Mars ] April Flowers for redOrbit.com - Your Universe Online Hunks of dry ice — carbon dioxide — may glide down Martian sand dunes like miniature hovercraft, riding on cushions of gas and plowing furrows as they go, according to new research from NASA. The research team suggests that this process could explain an enigmatic class of gullies seen on Martian sand dunes, coming to this conclusion by examining images from NASA's Mars...

Opportunity Rover Finds Martian Rock With Unique Composition
2013-05-18 04:32:57

redOrbit Staff & Wire Reports - Your Universe Online NASA´s Mars Exploration Rover Opportunity has discovered a pale rock that has a higher composition of aluminum and silica and a lower concentration of calcium and iron than any other rock it has examined during its time on Mars, the US space agency announced on Friday. The fractured rock, which is known as “Esperance,” is located in the “Cape York” region of Mars and was said to have been...

Mars Is Bombarded By 200 Asteroids A Year
2013-05-16 04:04:41

Lee Rannals for redOrbit.com - Your Universe Online Scientists believe Mars may be rocked by more than 200 small asteroids or bits of comets per year. Researchers using images from NASA's Mars Reconnaissance Orbiter identified 248 new impact sites on parts of the Martian surface in the past decade. Their 200-impacts-per-year estimation is a calculation based on the number found in a systematic survey of a portion of the planet. MRO's High Resolution Imaging Science Experiment...

Martian Snowstorms Can Be Forecast Weeks Before They Occur
2013-05-09 09:43:53

April Flowers for redOrbit.com - Your Universe Online A new study from an international group of researchers led by the Max Planck Institute for Solar System Research (MPS) reveals that snowstorms that lash the northern hemisphere of Mars during the harsh winters may be predicted several weeks in advance. The team´s calculations reveal a connection between the snowfalls and a weather phenomenon special to Mars: fluctuations of pressure, temperature, wind speeds and directions that...

Mars Orbiter Finds Evidence Of Soviet Union Lander
2013-04-12 05:38:54

April Flowers for redOrbit.com - Your Universe Online NASA's Mars Reconnaissance Orbiter may have captured images of hardware from a Soviet era spacecraft that landed on Mars in 1971. Russian citizen enthusiasts were following news about NASA's Curiosity rover and Mars when they found four features in a five-year old image from the Mars Reconnaissance Orbiter. The features resemble four pieces of hardware from the Soviet Mars 3 mission: the parachute, heat shield, terminal retrorocket...

Used Parachute From Curiosity Rover Flaps In The Wind On Mars
2013-04-03 14:10:32

NASA's Jet Propulsion Laboratory Photos from NASA's Mars Reconnaissance Orbiter show how the parachute that helped NASA's Curiosity rover land on Mars last summer has subsequently changed its shape on the ground. The images were obtained by the High Resolution Imaging Science Experiment (HiRISE) camera on Mars Reconnaissance Orbiter. Seven images taken by HiRISE between Aug. 12, 2012, and Jan. 13, 2013, show the used parachute shifting its shape at least twice in response to wind....

Ancient Mars Riverbed Evidence Found
2013-01-29 18:38:25

Lee Rannals for redOrbit.com — Your Universe Online More evidence is coming in Mars used to be thriving with ancient riverbeds, according to a study published in the journal Geophysical Research Letters. Brown University researchers found networks of narrow ridges in impact craters on Mars that appear to be fossilized remnants of underground cracks through which water once flowed. The study adds more weight to the growing pile of evidence Mars once had an active hydrology and...
