[ Watch the Video: Searching for Mars' Missing Atmosphere ] Lee Rannals for redOrbit.com - Your Universe Online NASA's Curiosity rover has helped bring in some new insights about how Mars lost its original atmosphere. Scientists believe the original Martian atmosphere was much thicker than it is today, leading many to wonder how it became so thin. The Mars Curiosity laboratory has provided some clues into this mystery, which scientists recently reported about in the journal Science....

Mars Reconnaissance Orbiter Samples Mars' Atmosphere And Finds A Surprise
2013-06-13 11:55:13

Lee Rannals for redOrbit.com - Your Universe Online Researchers have discovered that temperatures in the Martian atmosphere regularly rise and fall twice a day. According to the findings published in the journal Geophysical Research Letters, temperatures can swing by as much as 58 degrees Fahrenheit during this odd, twice-a-day pattern. The observations, made possible by NASA's Mars Reconnaissance Orbiter, show that the temperature drop takes place globally and year-round. "We see a...

Martian Snowstorms Can Be Forecast Weeks Before They Occur

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...

Volcanic Activity Would Have Helped Mars Sustain Liquid Water
2013-04-09 10:17:31

Brett Smith for redOrbit.com - Your Universe Online A new study suggests that Earth´s atmosphere is largely the product of carbon dioxide gas moving from the mantle to the surface through volcanic activity; if similar activity were to happen on Mars — the planet would be able to sustain liquid water. According to the study, which appeared in the early online edition of Proceedings of the National Academy of Sciences (PNAS), greenhouse gases such as methane and carbon dioxide...

NASA Curiosity Finds Evidence Of Atmosphere Thinning On Mars
2013-04-08 11:54:31

Lawrence LeBlond for redOrbit.com - Your Universe Online NASA´s Curiosity rover has been busy searching for signs that life may have once existed on the Red Planet. In the eight months since NASA dropped the rover on Mars, it has made significant progress in the hunt for water and life. In the latest round of evidence pertaining to Mars´ past, new measurements from Curiosity point towards the sky. These measurements, which consisted of analysis of Argon atoms in the...

MAVEN Receives Final Instrument
2013-04-04 11:54:13

NASA An instrument that will measure the composition of Mars' upper atmosphere has been integrated into NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft. MAVEN has a scheduled launch date of Nov. 18. Engineers and scientists at NASA's Goddard Space Flight Center in Greenbelt, Md., in collaboration with partners at the University of Michigan, Ann Arbor; Battel Engineering, Scottsdale, Ariz., and AMU Engineering, Miami, Fla., built the Neutral Gas and Ion Mass Spectrometer...

Is Mars Hot or Cold?
2013-02-08 14:49:48

Alan McStravick for redOrbit.com - Your Universe Online With all the attention being paid to Mars, we are learning something new about the red planet almost daily. Each new revelation is pretty heady information. But what about the weather on our celestial neighbor? One of the most common questions that people have is whether Mars is hot or cold. The early days of Earth was marked by a climate that was both warm and wet, and mirrors what Mars was like some 3.5 billion years ago....

Meteorite Linked To Martian Crust
2013-01-03 13:08:12

Lee Rannals for redOrbit.com - Your Universe Online Researchers have identified a new class of Martian meteorite that they believe originated from Mars' crust. The team wrote in Thursday's issue of Science Express that this new meteorite contains more water than any other Martian meteorite ever found. The sample is the only one found that dates back to 2.1 billion years ago, which is an early era on Mars known as the Amazonian. The meteorite, known as Northwest Africa (NWA) 7034,...

ExoMars Agreement Approved Between Europe And Russia
2012-11-21 08:56:15

April Flowers for redOrbit.com - Your Universe Online Russia has come to an agreement with the European Space Agency (ESA) member states to take a significant role in planned Red Planet missions in 2016 and 2018. The 2016 mission will look for methane and other trace gases in the atmosphere and another in 2018 that aims to put a rover on the Martian surface. Russia stepping up fills a void left by the US who pulled back from the projects earlier this year. The American withdrawal looked...
