What Happened To Mars Is A Planetary Mystery
2013-11-13 12:46:07

[ Watch The Video: ScienceCasts: What Happened to Mars? A Planetary Mystery ] NASA Science Billions of years ago when the planets of our solar system were still young, Mars was a very different world. Liquid water flowed in long rivers that emptied into lakes and shallow seas. A thick atmosphere blanketed the planet and kept it warm. In this cozy environment, living microbes might have found a home, starting Mars down the path toward becoming a second life-filled planet next door...

What Are Clouds On Mars Like?
2013-10-08 04:34:52

[ Watch the Video: Simulating Martian Clouds ] April Flowers for redOrbit.com - Your Universe Online The clouds on Mars, at first glance, might be easily mistaken for those on Earth. NASA's Opportunity rover returned images of the Martian sky with gauzy, high-altitude wisps that are similar to our cirrus clouds. These clouds most likely consist of either carbon dioxide or water-based ice crystals, given what scientists currently understand about the Martian atmosphere. However,...

Mars Atmosphere
2013-07-18 16:00:41

[ 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
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...

Surface Features of Mars
2013-02-06 16:59:45

Alan McStravick for redOrbit.com - Your Universe Online Scientists will never know who first looked to the heavens and noticed the pale pink, barely visible orb that graces our early morning skies. We do know the Greeks named the red planet Ares in honor of their god of war. It wasn´t until the Romans came on the scene and renamed this celestial sphere for their own god of war, however, that we came to know our heavenly neighbor as Mars. Over the years, Mars has received a lot of...

NASA Spacecraft Monitoring Martian Dust Storm
2012-11-22 07:52:09

NASA/JPL Report 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. Using the orbiter's Mars Color Imager, Bruce Cantor of Malin Space Science Systems, San Diego, began observing the storm on Nov. 10, and subsequently reported it to the team operating NASA's Mars Exploration Rover Opportunity. The storm came no closer than about 837 miles (1,347 kilometers) from Opportunity,...

Mars Curiosity Rover Prepares For Thanksgiving Celebration Festivities
2012-11-20 15:53:19

Lee Rannals for redOrbit.com — Your Universe Online It may not be in the company of little Martians, but NASA's Curiosity is determined to celebrate Thanksgiving this year with, or without, the company of extra-terrestrials. For its Thanksgiving festivities, the rover plans to use its Mast Camera (Mastcam) to examine possible routes and targets to the east. NASA said its priority is to choose a rock for the first use of the rover's hammering drill, which will collect samples...

Mars Mission Instrument Package Delivered
2012-11-17 05:25:38

redOrbit Staff & Wire Reports - Your Universe Online The remote sensing instrument package that will be a key part of an upcoming NASA mission investigating how Mars could have lost its atmosphere is ready for integration into the spacecraft. The $20 million package -- which was built at the University of Colorado Boulder (CU-Boulder) Laboratory for Atmospheric and Space Physics (LASP) and includes the Imaging UltraViolet Spectrograph (IUVS), its electronic control box, the Remote...

Melt Water On The Red Planet Could Support Life
2012-11-16 16:47:39

Michael Harper for redOrbit.com — Your Universe Online Though Mars is 140 million miles away, it shares some similarities with Earth. Some of its landforms, for existence, closely resemble regions found here on Earth. It is by researching these similar landforms and landscapes that researchers are able to gather some assumptions about how these martian landscapes were formed. If the two areas look the same, perhaps they were created in the same way as well. Dr. Andreas...
