NASA’s Opportunity Mars Rover Mission Ends

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – One of the most successful and enduring feats of interplanetary exploration, NASA’s Opportunity rover mission is at an end after almost 15 years exploring the surface of Mars and helping lay the groundwork for NASA’s return to the Red Planet.

The Opportunity rover stopped communicating with Earth when a severe Mars-wide dust storm blanketed its location in June 2018. After more than a thousand commands to restore contact, engineers in the Space Flight Operations Facility at NASA’s Jet Propulsion Laboratory (JPL) made their last attempt to revive Opportunity Tuesday, to no avail. The solar-powered rover’s final communication was received June 10th.

NASA studies elements that make a Stable Landslide into a disastrous one

 

Written by Carol Rasmussen
NASA’s Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – “Stable landslide” sounds like a contradiction in terms, but there are indeed places on Earth where land has been creeping downhill slowly, stably and harmlessly for as long as a century. But stability doesn’t necessarily last forever.

For the first time, researchers at NASA’s Jet Propulsion Laboratory in Pasadena, California, and collaborating institutions have documented the transition of a stable, slow-moving landslide into catastrophic collapse, showing how drought and extreme rains likely destabilized the slide.

The radar velocity map shows the pre-collapse (solid line) and post-collapse (dashed line) extent of the sliding area, with faster sliding velocities before the collapse shown in darker shades of red. The highest velocities were about 16 inches (40 centimeters) per year. (Google/SIO/NOAA/U.S. Navy/NGA/GEBCO/Landsat/Copernicus)

American Heart Association says Climate Change may increase Congenital Heart Defects

 

Journal of the American Heart Association Report

American Heart AssociationDallas, TX – Rising temperatures stemming from global climate change may increase the number of infants born with congenital heart defects (CHD) in the United States over the next two decades and may result in as many as 7,000 additional cases over an 11 year-period in eight representative states (Arkansas, Texas, California, Iowa, North Caroline, Georgia, New York and Utah), according to new research in the Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

The greatest percentage increases in the number of congenital heart defects are predicted in the Midwest, followed by the Northeast and the South. (American Heart Association)

AAA reports United States Gas Price Averages Inching Up Amid Rising Demand

 

AAA

AAATampa, FL – Many motorists filling up across the country are noticing gas prices that are increasing slightly. While nearly 25 states’ averages increased on the week, the national average is only a penny more than a week ago at $2.26.

The fluctuating national and state gas price averages come alongside an increase in gasoline demand and reflect the higher crude oil prices as of late, but it’s likely not to be a long-term trend.

While nearly 25 states’ averages increased on the week, the national average is only a penny more than a week ago. (AAA)
