NASA Laser Communications research may lead to faster data transfer in Space

NASA - National Aeronautics and Space AdministrationPasadena, CA – Thought your Internet speeds were slow? Try being a space scientist for a day.

The vast distances involved will throttle data rates to a trickle. You’re lucky if a spacecraft can send more than a few megabits per second (Mbps).

But we might be on the cusp of a change. Just as going from dial-up to broadband revolutionized the Internet and made high-resolution photos and streaming video a given, NASA may be ready to undergo a similar “broadband” moment in coming years.

NASA’s Goldstone Solar System Radar images Asteroid as it passes by Earth

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Radar images of asteroid 2017 BQ6 were obtained on February 6th and 7th with NASA’s 70-meter (230-foot) antenna at the Goldstone Deep Space Communications Complex in California. They reveal an irregular, angular-appearing asteroid about 660 feet (200 meters) in size that rotates about once every three hours. The images have resolutions as fine as 12 feet (3.75 meters) per pixel.

“The radar images show relatively sharp corners, flat regions, concavities, and small bright spots that may be boulders,” said Lance Benner of NASA’s Jet Propulsion Laboratory in Pasadena, California, who leads the agency’s asteroid radar research program.

This composite of 25 images of asteroid 2017 BQ6 was generated with radar data collected using NASA's Goldstone Solar System Radar in California's Mojave Desert. (NASA/JPL-Caltech/GSSR)

AAA says Gas Prices Remain Stable Despite Record Low Demand

 

AAATampa, FL – The national average price of regular unleaded gasoline remained relatively stable over the past week, settling at today’s price of $2.27 per gallon.

Although today’s average remains flat compared to one week ago, drivers are paying ten cents less per gallon month-over-month, and 52 cents more per gallon year-over-year.

NASA looks at the Super Bowl – 5 Things Football has in Common with Space

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – As Super Bowl LI in Houston Texas approaches and players, coaches and a host of personnel behind the scenes prepare for the big game in Space City, NASA remains on the cutting edge of human space exploration, setting its sights on the journey to Mars.

A football player’s journey to the end zone, though, has a lot more in common to space exploration than one might think.

Here are five similarities.

AAA reports National Gas Price Average Drops for 21 Consecutive Days

 

AAATampa, FL – Continual growth in the number of U.S. oil rigs and the increased drilling it implies are raising expectations for a climb in domestic oil production. Additionally, increased U.S. crude oil production coupled with lower driving demand has kept downward pressure on the national average price at the pump, which has fallen for 21 consecutive days.

Today’s national average price for regular unleaded gasoline is $2.27 per gallon, down four cents versus one week ago, five cents less than one month ago, but 47 cents more per gallon year-over-year.

NASA reports Snow Storms over Sierra Nevada recoups 37 percent of California Water Deficit

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The “atmospheric river” weather patterns that pummeled California with storms from late December to late January may have recouped 37 percent of the state’s five-year snow-water deficit, according to new University of Colorado Boulder-led research using NASA satellite data.

Researchers at the university’s Center for Water Earth Science and Technology (CWEST) estimate that two powerful recent storms deposited roughly 17.5-million acre feet (21.6 cubic kilometers) of water on California’s Sierra Nevada range in January.

January storms in the Sierra Nevadas reduced California's deficit in stored snow water by about 37 percent. (Perfect Zero, CC BY 2.0)

NASA says New Test to help search for Life in the Universe

 

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A simple chemistry method could vastly enhance how scientists search for signs of life on other planets.

The test uses a liquid-based technique known as capillary electrophoresis to separate a mixture of organic molecules into its components. It was designed specifically to analyze for amino acids, the structural building blocks of all life on Earth.

The method is 10,000 times more sensitive than current methods employed by spacecraft like NASA’s Mars Curiosity rover, according to a new study published in Analytical Chemistry. The study was carried out by researchers from NASA’s Jet Propulsion Laboratory, Pasadena, California.

AAA reports Increased U.S. Oil Production Pushes Pump Prices Lower

 

AAATampa, FL – The national average price of gas continues to decline as U.S. oil production increases. Today’s average price of $2.31 per gallon represents a decrease of three cents per gallon on the week, four cents per gallon on the month, and prices have moved lower for 14 of the past 15 days.

Despite this recent trend lower, retail averages are up by 46 cents per gallon as compared to one year ago.

AAA reports Pump Prices have Dropped for Eight Consecutive Days

 

AAATampa, FL – Gas prices have fallen for eight consecutive days, reaching today’s national average price of $2.34 per gallon. The price of retail gasoline has retreated since last week with today’s average three cents less per gallon than one week ago, but ten cents more than one month ago and 43 cents more per gallon year-over-year.

The slight decrease in retail prices can be attributed to less demand and adequate supply, but this downward dip may only be temporary as the market awaits OPEC’s December monthly output report which is due out later this week.
