NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA is set to launch its first Earth science small satellite constellation, which will help improve hurricane intensity, track and storm surge forecasts, on December 12th from Cape Canaveral Air Force Station in Florida.

The Cyclone Global Navigation Satellite System (CYGNSS) hurricane mission will measure previously unknown details crucial to accurately understanding the formation and intensity of tropical cyclones and hurricanes. Derek Posselt of NASA’s Jet Propulsion Laboratory, Pasadena, California, is the deputy principal investigator.

From Hurricanes to Forrest Fires, Tennessee National Guard Wraps Up Busy Week

 

Tennessee Emergency Management AgencyNashville, TN – The Tennessee Army National Guard sent helicopters and crews to South Carolina late last week as the state made preparations ahead of Hurricane Matthew’s arrival.

The rotary wing assets were requested by South Carolina through the Emergency Management Assistance Compact process whereby states can ask for help in time of crisis, or other natural disasters.

The Tennessee Emergency Management Agency serves as the mitigating agency for such requests and works regularly with other state emergency management agencies to facilitate these cooperative agreements.

NASA Satellites and Airborne Instruments examine Hurricane Matthew

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Hurricane forecasters use many different types of data to forecast a storm’s intensity and track. NASA satellites and airborne instruments, including several developed and operated by NASA’s Jet Propulsion Laboratory, Pasadena, California, contribute to scientists’ understanding of tropical cyclones and help improve forecasts.

Here are some of the latest data on Hurricane Matthew from JPL-developed satellites and instruments:

NASA tracks Hurricane Matthew as it Heads for the Bahamas

 

Written by Rob Gutro
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Satellites from NASA and NOAA have been tracking and analyzing powerful Hurricane Matthew since its birth just east of the Leeward Islands on September 28th.

On October 4th, 2016, Hurricane Matthew made landfall on southwestern Haiti as a category-4 storm—the strongest storm to hit the Caribbean nation in more than 50 years. Just hours after landfall, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired a natural-color image that showed the western extent over the eastern tip of Cuba and the eastern-most extent over Puerto Rico.

AAA says Gas Prices suddenly jump in the South

 

‘Colin’ could impact gas prices in Florida

AAATampa, FL – Motorists in Georgia and Tennessee saw gas prices increase last week, but not by nearly as much as those in Florida. Since last Sunday, state averages rose 1-cent in Georgia, 4 cents in Tennessee, and 10 cents in Florida.

“Minimal increases at the pump were understandable, because of increased holiday demand and delayed reaction to rising crude prices, but the dramatic increases seen in Florida came a surprise,” said Mark Jenkins, spokesman, AAA – The Auto Club Group.

NASA explores possible suborbital platform with Airship Challenge

 

Written by Elizabeth Landau/Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Airships aren’t just powered balloon-like vehicles that hover above sporting events. Researchers at NASA’s Jet Propulsion Laboratory in Pasadena, California, are floating the idea that airships have potential for important scientific and commercial uses.

NASA is considering issuing a challenge for developing stratospheric airships that can break records in terms of duration of flight at high altitudes. The agency has issued a request for information for this contemplated “20-20-20 Airship Challenge.” Submissions will be accepted until December 1st.
