NASA Mars spacecraft reveals a more dynamic red planet
(Phys.org) —NASA's Mars Reconnaissance Orbiter has revealed to scientists slender dark markings—possibly due to salty water - that advance seasonally down slopes surprisingly close to the Martian equator.
Curiosity providing new weather and radiation data about Mars
(Phys.org)—Observations of wind patterns and natural radiation patterns on Mars by NASA's Curiosity rover are helping scientists better understand the environment on the Red Planet's surface.
Dry ice lake suggests Mars once had a 'Dust Bowl' (Update)
(PhysOrg.com) -- NASA's Mars Reconnaissance Orbiter has discovered the total amount of atmosphere on Mars changes dramatically as the tilt of the planet's axis varies. This process can affect the stability ...
Methane on Mars may be result of electrification of dust-devils
Methane on Mars has long perplexed scientists; the short-lived gas has been measured in surprising quantities in Mars' atmosphere over several seasons, sometimes in fairly large plumes. Scientists have taken ...
Curiosity's second day on Mars 'flawless': NASA
NASA rover Curiosity's second day on Mars went "flawlessly," NASA said, confirming the antennas, communication links and generator on the $2.5 billion robot are all working well.
Mars rover surpasses Viking 1's longevity record
Pop quiz: What spacecraft holds the record for longest-surviving mission on the bitterly cold and dusty surface of Mars? As of Thursday, there's a new - but possibly temporary - champion.
New study links dust to increased glacier melting, ocean productivity
A University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led study shows a link between large dust storms on Iceland and glacial melting. The dust is both accelerating glacial melting ...
Massive clouds erupted 260km into Martian atmosphere – and no one knows why
Enormous cloud-like plumes reaching 260km above the surface of Mars have left scientists baffled. This is way beyond Mars's normal weather, reaching into the exosphere where the atmosphere merges with interplanetary ...
Mars Reconnaissance Orbiter monitoring dust storm
(Phys.org)—A Martian dust storm that NASA's Mars Reconnaissance Orbiter has been tracking since last week has also produced atmospheric changes detectable by rovers on Mars. ...
Dust plays larger than expected role in determining Atlantic temperature
(PhysOrg.com) -- The recent warming trend in the Atlantic Ocean is largely due to reductions in airborne dust and volcanic emissions during the past 30 years, according to a new study.
Regional dust storm dissipating
(Phys.org)—A regional dust storm on Mars, tracked from orbit since Nov. 10, appears to be abating rather than going global.
1934 drought was worst of the last millennium, study finds
The 1934 drought was by far the most intense and far-reaching drought of the last 1,000 years in North America, and was caused in part by an atmospheric phenomenon that may have also led to the current drought ...
Saharan dust impacts West African monsoon precipitation
(PhysOrg.com) -- Africa's Saharan Desert is the largest source of mineral dust in the world, covering more than 3 million square miles and causing dust particles to blanket African skies. According to Pacific ...
NASA probes hit moon twice (Update 2)
NASA's Lunar Crater Observation and Sensing Satellite, or LCROSS, created twin impacts on the moon's surface early Friday in a search for water ice. Scientists will analyze data from the spacecraft's instruments ...
