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.

AAA reports August Gas Prices hit 4-Year Low

 

AAATampa, FL – Motorists heading to the gas pumps are finding the cheapest August gas prices since 2010. On August 1st, 2010, the national average price was $2.74. Since that time, average prices on August 1 ranged from $3.52 in 2012, to $3.71 in 2011.

The current average of $3.50 is 3 cents cheaper than last week and the discount at the pump should continue in the near future. «Read the rest of this article»

AAA say U.S. Delared World’s Biggest Oil Producer; Gas Prices Drift Lower

 

AAATampa, FL – The United States surpassed Saudi Arabia and Russia to become the world’s biggest oil producer this year.

According to a report from the Bank of America Corp., the U.S. is projected to remain the top producer of 2014 because domestic output is forecast to increase and production growth outside the U.S. has been lower than anticipated. «Read the rest of this article»

NASA to launch five Earth Science Missions in 2014

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – For the first time in more than a decade, five NASA Earth science missions will be launched into space in the same year, opening new and improved remote eyes to monitor our changing planet.

The five launches, including two to the International Space Station (ISS), are part of an active year for NASA Earth science researchers, who also will conduct airborne campaigns to the poles and hurricanes, develop advanced sensor technologies, and use satellite data and analytical tools to improve natural hazard and climate change preparedness.

NASA reports on the effects of Strong Solar Flares

 

Written by Karen C. Fox
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Given a legitimate need to protect Earth from the most intense forms of space weather — great bursts of electromagnetic energy and particles that can sometimes stream from the sun — some people worry that a gigantic “killer solar flare” could hurl enough energy to destroy Earth, but this is not actually possible.

Solar activity is indeed currently ramping up toward what is known as solar maximum, something that occurs approximately every 11 years. However, this same solar cycle has occurred over millennia so anyone over the age of 11 has already lived through such a solar maximum with no harm.

The Solar and Heliospheric Observatory spacecraft captured this image of a solar flare as it erupted from the sun early on Nov 4, 2003. This was the most powerful flare measured with modern methods, classified as an X28. (Credit: ESA and NASA/SOHO)

NASA’s Cassini spacecraft spots huge Hurricane at Saturn’s North Pole

 

Written by Dr. Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Cassini spacecraft has provided scientists the first close-up, visible-light views of a behemoth hurricane swirling around Saturn’s north pole.

In high-resolution pictures and video, scientists see the hurricane’s eye is about 1,250 miles (2,000 kilometers) wide, 20 times larger than the average hurricane eye on Earth. Thin, bright clouds at the outer edge of the hurricane are traveling 330 mph(150 meters per second). The hurricane swirls inside a large, mysterious, six-sided weather pattern known as the hexagon.

NASA to send ISS-RapidScat instrument to International Space Station to measure Ocean Winds

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – In a clever reuse of hardware originally built to test parts of NASA’s QuikScat satellite, the agency will launch the ISS-RapidScat instrument to the International Space Station in 2014 to measure ocean surface wind speed and direction.

The ISS-RapidScat instrument will help improve weather forecasts, including hurricane monitoring, and understanding of how ocean-atmosphere interactions influence Earth’s climate.

NASA Satellites monitor Hurricane Sandy

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Hurricane Sandy is expected to affect as many as 60 million Americans this week as it combines with other weather fronts to create an anticipated ‘superstorm.’ Satellites and instruments from NASA’s Jet Propulsion Laboratory, Pasadena, CA, are busy monitoring the storm. NASA’s Atmospheric Infrared Sounder Tracks Sandy’s Approach

NASA’s Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua spacecraft captured this infrared image of Hurricane Sandy at 2:17pm EDT on October 29th, 2012.

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA has begun its latest hurricane science field campaign by flying an unmanned Global Hawk aircraft over Hurricane Leslie in the Atlantic Ocean during a day-long flight that began in California and ended in Virginia.

With the Hurricane and Severe Storm Sentinel (HS3) mission, NASA for the first time will be flying Global Hawks from the U.S. East Coast.

An unmanned NASA Global Hawk aircraft comes in for a landing at NASA's Wallops Flight Facility on Wallops Island, VA, Sept. 7, kicking off the month-long Hurricane and Severe Storm Sentinel (HS3) mission. HS3 will help researchers and forecasters uncover information about how hurricances and tropical storms form and intensify. (Image credit: NASA)

Tennessee National Guard Prepares for Hurricane Response

 

Tennessee Military DepartmentNashville, TN – Soldiers and Airmen across Tennessee are preparing for a possible activation of National Guard troops, facilities, and equipment in response to the potential landfall of Hurricane Irene.

“We were contacted by National Guard Bureau Wednesday to determine what resources we can provide should the hurricane move inland along the East Coast,” said Brig. Gen. Robert Harris, Tennessee’s Assistant Adjutant General-Army.
