NASA researchers say Mars may have had Rings

 

Written by Brian Wallheimer
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – As children, we learned about our solar system’s planets by certain characteristics — Jupiter is the largest, Saturn has rings, Mercury is closest to the sun. Mars is red, but it’s possible that one of our closest neighbors also had rings at one point and may have them again someday.

That’s the theory put forth by NASA-funded scientists at Purdue University, Lafayette, Indiana, whose findings were published in the journal Nature Geoscience. David Minton and Andrew Hesselbrock developed a model that suggests that debris that was pushed into space from an asteroid or other body slamming into Mars around 4.3 billion years ago alternates between becoming a planetary ring and clumping together to form a moon.

Marsha Blackburn spends time with Rossview Elementary students

 

Congressman Marsha Blackburn

7th District of Tennessee

U.S. Congress

Washington, D.C. – On Monday, I spent time with some amazing children from the Clarksville area. The 1st and 2nd graders from Rossview Elementary invited me to read with them. We read the book called One Proud Penny and talked about how pennies are made. They were great readers and very curious about my job as a U.S. Congressman.

Later in the afternoon, I had lunch with Robyn Gordon, an inspirational 13-year-old who has written a children’s book called Stop Bullying. Robyn is a brave and courageous young woman who was bullied when she was 6.

NASA study shows hydrocarbon seas on Saturn’s moon Titan could bubble with Nitrogen

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A recent NASA-funded study has shown how the hydrocarbon lakes and seas of Saturn’s moon Titan might occasionally erupt with dramatic patches of bubbles.

For the study, researchers at NASA’s Jet Propulsion Laboratory in Pasadena, California, simulated the frigid surface conditions on Titan, finding that significant amounts of nitrogen can be dissolved in the extremely cold liquid methane that rains from the skies and collects in rivers, lakes and seas.

AAA reports Gas Prices Make Slow 10 Day Decline

 

AAATampa, FL – After remaining relatively flat, the national average price for regular unleaded gasoline has now fallen for 10 straight days to today’s average of $2.30 per gallon.

Today’s national average is one cent less than one week ago and two cents more than one month ago. Compared to this same date last year, consumers are paying 37 cents more per gallon at the pump.

NASA’s Kepler Space Telescope provides additional data on system with 7 Earth Size Planets

 

Written by Michele Johnson
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – On February 22nd, astronomers announced that the ultra-cool dwarf star, TRAPPIST-1, hosts a total of seven Earth-size planets that are likely rocky, a discovery made by NASA’s Spitzer Space Telescope in combination with ground-based telescopes.

NASA’s planet-hunting Kepler space telescope also has been observing this star since December 2016. Today these additional data about TRAPPIST-1 from Kepler are available to the scientific community.

Gas Prices Remain Steady Despite Increased U.S. Production reports AAA

 

AAATampa, FL – Oil prices slipped fractions of a penny over the weekend, reaching today’s national average price for regular unleaded gasoline of $2.31 per gallon. Today’s price is still two cents more than one week ago, four cents more compared to one month ago and 50 cents more per gallon year-over-year.

Retail prices continue to fluctuate but have remained between $2.28-2.32 for more than a month as reports of increased U.S. production continues to counter OPEC rebalancing efforts.

NASA to use Super Low Temperatures to slow Atoms for observation on International Space Station

 

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – This summer, an ice chest-sized box will fly to the International Space Station, where it will create the coolest spot in the universe.

Inside that box, lasers, a vacuum chamber and an electromagnetic “knife” will be used to cancel out the energy of gas particles, slowing them until they’re almost motionless. This suite of instruments is called the Cold Atom Laboratory (CAL), and was developed by NASA’s Jet Propulsion Laboratory in Pasadena, California. CAL is in the final stages of assembly at JPL, ahead of a ride to space this August on SpaceX CRS-12.

Its instruments are designed to freeze gas atoms to a mere billionth of a degree above absolute zero. That’s more than 100 million times colder than the depths of space.

NASA’s James Webb Space Telescope to examine Seven Earth Sized Planets

 

Written by Laura Betz
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – With the discovery of seven earth-sized planets around the TRAPPIST-1 star 40 light years away, astronomers are looking to the upcoming James Webb Space Telescope to help us find out if any of these planets could possibly support life.

“If these planets have atmospheres, the James Webb Space Telescope will be the key to unlocking their secrets,” said Doug Hudgins, Exoplanet Program Scientist at NASA Headquarters in Washington. “In the meantime, NASA’s missions like Spitzer, Hubble, and Kepler are following up on these planets.”
