NASA’s Mars Curiosity rover discovers Ancient Organic Molecules on Mars

 

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Curiosity rover has found new evidence preserved in rocks on Mars that suggests the planet could have supported ancient life, as well as new evidence in the Martian atmosphere that relates to the search for current life on the Red Planet. While not necessarily evidence of life itself, these findings are a good sign for future missions exploring the planet’s surface and subsurface.

The new findings — “tough” organic molecules in 3-billion-year-old sedimentary rocks near the surface, as well as seasonal variations in the levels of methane in the atmosphere — appear in the June 8th edition of the journal Science.

NASA’s Cassini Spacecraft observes Saturn’s Solstice

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini spacecraft still has a few months to go before it completes its mission in September, but the veteran Saturn explorer reaches a new milestone today. Saturn’s solstice — that is, the longest day of summer in the northern hemisphere and the shortest day of winter in the southern hemisphere — arrives today for the planet and its moons.

The Saturnian solstice occurs about every 15 Earth years as the planet and its entourage slowly orbit the sun, with the north and south hemispheres alternating their roles as the summer and winter poles.

These natural color views from Cassini show how the color of Saturn's north-polar region changed between June 2013 and April 2017, as the northern hemisphere headed toward summer solstice. (NASA/JPL-Caltech/SSI/Hampton Univ.)

Tennessee State Fire Marshal’s Office shares Safety Tips for Outdoor Grilling

 

Tennessee State Fire MarshalNashville, TN – Summertime is the peak season for outdoor grilling and grilling fires. This year, the Tennessee State Fire Marshal’s Office urges outdoor cooks to keep fire safety in mind as they start up the grill this summer.

From 2010-2014, Tennessee fire departments responded to 204 fires involving grills, hibachis or barbeques. Those fires resulted in two civilian injuries, two firefighter injuries and $5.9 million in property damage, according to the Tennessee Fire Incident Reporting System (TFIRS).

NASA’s Cassini Mission has found that Methane Rainfall on Saturn’s moon Titan is being transformed underground lakes

 

Written by Preston Dyches

NASA - National Aeronautics and Space AdministrationPasadena, CA – The NASA and European Space Agency Cassini mission has revealed hundreds of lakes and seas spread across the north polar region of Saturn’s moon Titan. These lakes are filled not with water but with hydrocarbons, a form of organic compound that is also found naturally on Earth and includes methane.

The vast majority of liquid in Titan’s lakes is thought to be replenished by rainfall from clouds in the moon’s atmosphere. But how liquids move and cycle through Titan’s crust and atmosphere is still relatively unknown.

Tennessee State Fire Marshal’s Office says be Grill Savvy and Fire Safe this Summer

 

Make sure the only thing going up in smoke is dinner! 

Tennessee State Fire MarshalNashville, TN – It is summer in Tennessee and that means its grilling time for many residents. Although, outdoor cooking is a long-cherished tradition for most families, it also increases the possibility of fire-related incidents and injuries.

Gas grills constitute a higher risk, having been involved in an annual average of 7,200 home fires in 2007-2011, while charcoal or other solid-fueled grills were involved in an annual average of 1,400 home fires.

Tennessee State Fire Marshal Issues Order to Waive Propane Delivery Restrictions During State of Emergency

 

Tennessee State Fire MarshalNashville, TN – Commissioner and State Fire Marshal Julie Mix McPeak issued an order this afternoon to exempt Tennessee home and business owners from propane delivery restrictions in order to obtain needed propane.

“Heating homes and businesses is a priority during this cold weather snap,” said McPeak. “This order allows individuals to purchase propane from any dealer with available resources to help keep Tennesseans warm and in business while we manage these frigid temperatures.” «Read the rest of this article»

NASA’s Cassini Spacecraft detects Propylene, key Ingredient of Plastic on Saturn’s moon Titan

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini spacecraft has found propylene, a chemical used to make food-storage containers, car bumpers and other consumer products, on Saturn’s moon Titan.

This is the first definitive detection of the plastic ingredient on any moon or planet, other than Earth.

A small amount of propylene was identified in Titan’s lower atmosphere by Cassini’s composite infrared spectrometer (CIRS). This instrument measures the infrared light, or heat radiation, emitted from Saturn and its moons in much the same way our hands feel the warmth of a fire.

Tennessee State Fire Marshal’s Office offers Tips to be Safe while Camping this Summer

 

Tennessee State Fire MarshalNashville, TN – As Tennesseans pack up and head out to their favorite campsites, the State Fire Marshal’s Office urges campers to be aware of carbon monoxide dangers in and around tents and RVs.

Carbon monoxide (CO), often called “the silent killer,” is an invisible, odorless gas created when fuels (such as kerosene, gasoline, wood, coal, natural gas, propane, oil, and methane) burn incompletely. Carbon monoxide can result from camping equipment, such as barbecue grills, portable generators or other fuel-powered devices.

Tennessee State Fire Marshal issues warning about carbon monoxide risks in the fall

 

Steer clear of carbon monoxide hazards this fall

Tennessee State Fire MarshalNashville, TN – According to the Consumer Product Safety Commission, each year in America more than 150 people die from accidental, non-fire related carbon monoxide (CO) poisoning associated with consumer products.

These products include faulty, improperly used or incorrectly vented fuel-burning appliances such as furnaces, stoves, water heaters and fireplaces.

CO, often called “the silent killer,” is a gas you cannot see, taste, or smell. It can be created when fossil fuels, such as kerosene, gasoline, coal, natural gas, propane, methane or wood do not burn properly. «Read the rest of this article»
