NASA model suggests Europa’s Plumes of Water Vapor could come from within it’s Icy Crust

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – Plumes of water vapor that may be venting into space from Jupiter’s moon Europa could come from within the icy crust itself, according to new research. A model outlines a process for brine, or salt-enriched water, moving around within the moon’s shell and eventually forming pockets of water – even more concentrated with salt – that could erupt.

Europa scientists have considered the possible plumes on Europa a promising way to investigate the habitability of Jupiter’s icy moon, especially since they offer the opportunity to be directly sampled by spacecraft flying through them.

This illustration of Jupiter's icy moon Europa depicts a cryovolcanic eruption in which brine from within the icy shell could blast into space. A new model proposing this process may also shed light on plumes on other icy bodies. (Justice Wainwright)

Future NASA Mars Rover to examine Habitat, Weather using MAHRS instruments

 

Written by Nancy Smith Kilkenny, ATS
NASA Glenn Research Center

NASA - National Aeronautics and Space AdministrationCleveland, OH – When human explorers embark on the journey to Mars, they need to know the natural conditions of the red planet before they arrive.  That’s why NASA sends rovers to the surface of Mars to photograph the landscape and operate scientific experiments to understand the habitat for humans or other kinds of life.

One of those future rover missions may host the Martian Aqueous Habitat Reconnaissance Suite (MAHRS), a set of five instruments that can take surface measurements in the search for habitable environments.

NASA studies Mars Canyons for signs of liquid water

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Puzzles persist about possible water at seasonally dark streaks on Martian slopes, according to a new study of thousands of such features in the Red Planet’s largest canyon system.

The study published today investigated thousands of these warm-season features in the Valles Marineris region near Mars’ equator. Some of the sites displaying the seasonal flows are canyon ridges and isolated peaks, ground shapes that make it hard to explain the streaks as resulting from underground water directly reaching the surface.

Tennessee Highway Patrol urges Tennesseans to prepare for Weather-Related Roadway Problems

 

Dial *THP from Cell Phone in case of Roadside Emergency

Tennessee Highway Patrol - THPNashville, TN – The Tennessee Highway Patrol (THP) is urging citizens to prepare for weather-related problems on the roads across the state this winter. Motorists are encouraged to dial *THP (*847) from a mobile phone for state trooper assistance in case of a roadside emergency.

“We want to make sure all Tennesseans are prepared in case they become stranded on the roads this winter. State troopers are standing by to assist motorists in the event of a roadside emergency during these extreme cold temperatures,” THP Colonel Tracy Trott said. «Read the rest of this article»

Tennessee Department of Transportation prepared for Winter Weather

 

Tennessee Department of TransportationNashville, TN  The Tennessee Department of Transportation is stocked and ready to clear roadways of ice and snow this season. Over the last several weeks, salt supplies have been replenished in all 95 counties, and crews have readied snow plows and brine trucks for the winter season.

“Tennessee often sees the bulk of its winter weather in January and February,” TDOT Commissioner John Schroer said. “Our salt bins are fully stocked and we have more than a thousand employees ready to mobilize in the event of inclement weather.”

TDOT Crews Ready to “Beet” Ice and Snow This Winter

 

New Tools to Help Keep Tennessee Roads Free of Ice and Snow This Season

NASHVILLE – Winter weather is here and the Tennessee Department of Transportation is ready to “beet” ice and snow this winter season using some new ice and snow removal tools, including beet juice.  This winter TDOT will use beet juice mixed with salt and salt brine at various locations across the state to improve the ability to remove snow and ice from state roads and interstates.  Beet juice is a by-product of the beet after the sugar has been extracted.  The department is also evaluating the effectiveness of larger snow plows and some new tools for applying salt and de-icing agents.

“Although we don’t typically see severe winters in the southeast, even small amounts of snow or ice can cripple our transportation system and create dangerous conditions for motorists,” said TDOT Commissioner Gerald Nicely. “This year, TDOT is testing a number of new weapons that all have the potential to help clear roads of ice and snow faster while also saving valuable time, manpower, and money.”

“The beet juice compound will help the salt stick to the roadway for a longer period of time which will make the salt and salt brine more effective and will help reduce the amount of salt used by TDOT,” said TDOT Chief Engineer Paul Degges. “The beet juice should also help reduce the amount of salt that bounces off the roadway when applied by the trucks.” «Read the rest of this article»

Brine Your Thanksgiving Turkey

 

turkey_baked I’ve been brining turkey for Thanksgiving each year for the past five years.  It makes a delicious, tender, juicy bird. And its not difficult to do! Here are instructions and some brine recipes for you to use this year.

To brine a turkey you will need a large pot that will hold the whole bird in the brine and a space in the frig large enough to store it for a day. You can improvise if your frig isn’t big enough. I have used buckets of ice and placed another bucket full of turkey and brine in it. For the last two years though, I have used a large, new trash bag to put the bird and brine in. I sit the bag with brine and turkey into a large cooler and surround the bag with ice. When the ice melts, I take the cooler to the back steps and let it drain, then fill it up with ice again.  You want to make sure the bird stays at or below 40*F.

I always start my turkey out defrosting on Saturday. By Wednesday it is usually thawed and ready for a 24 hour stint in the brine. «Read the rest of this article»

 

TDOT Adds to Winter Weather Arsenal

As Tennesseans enjoy the cooler temperatures and changing leaves of fall, TDOT Maintenance forces across the state are focused on the winter months ahead. Although we don’t typically see severe winters in the southeast, even small amounts of snow or ice can cripple our transportation system and create dangerous conditions for motorists. And, the wet weather pattern we’ve seen for much of 2009 makes one wonder if this could be a winter to remember.

When battling a winter weather event, time and resource limitations can be as formidable an opponent as the snow and ice that may be falling. This year, TDOT is testing a number of new weapons that all have the potential to save valuable time, manpower, and money. «Read the rest of this article»
