NASA’s WISE spacecraft reveals nearly five times more comets have passed the Sun then previously predicted

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Comets that take more than 200 years to make one revolution around the Sun are notoriously difficult to study. Because they spend most of their time far from our area of the solar system, many “long-period comets” will never approach the Sun in a person’s lifetime.

In fact, those that travel inward from the Oort Cloud — a group of icy bodies beginning roughly 186 billion miles (300 billion kilometers) away from the Sun — can have periods of thousands or even millions of years.

NASA’s WISE spacecraft, scanning the entire sky at infrared wavelengths, has delivered new insights about these distant wanderers.

NASA’s Cassini Spacecraft continues dives between Saturn and it’s Rings

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – As NASA’s Cassini spacecraft makes its unprecedented series of weekly dives between Saturn and its rings, scientists are finding — so far — that the planet’s magnetic field has no discernible tilt. This surprising observation, which means the true length of Saturn’s day is still unknown, is just one of several early insights from the final phase of Cassini’s mission, known as the Grand Finale.

Other recent science highlights include promising hints about the structure and composition of the icy rings, along with high-resolution images of the rings and Saturn’s atmosphere.

Recent images of features in Saturn's C ring called "plateaus" reveal a streaky texture that is very different from the textures of the regions around them. (NASA/JPL-Caltech/Space Science Institute)

Leading Health Organizations Seek to Intervene in Defense of FDA Rule on E-Cigarettes, Cigars

 

American Heart AssociationWashington, D.C. – Six leading public health organizations today asked federal courts to allow them to intervene in two lawsuits brought by the electronic cigarette and cigar industries against the Food and Drug Administration’s 2016 rule establishing public health oversight of e-cigarettes, cigars and other previously unregulated tobacco products.

The groups expressed concern that the Trump Administration may not adequately defend the rule (known as the “deeming rule”) or may seek to weaken or rescind it, putting the health of children and the public at risk.

Groups Express Concern Administration May Not Adequately Defend Essential Public Health Regulations Against Industry Challenges.

Marsha Blackburn: This Week From Washington – July 23rd, 2017

 

Congressman Marsha Blackburn

7th District of Tennessee

U.S. CongressWashington, D.C. – As the stories in the media on health care seemingly change from day to day, one thing remains clear: Americans deserve action. We must act. In addition to speaking with many of you, I spoke on a number of shows this week about the need to get something done on health care and what the Senate can do to make some progress on this issue.

The Senate is now considering a bill that has previously passed to repeal Obamacare with a two-year delay to allow Congress the time to craft and debate legislation that truly addresses the root problems of our high health care costs.

NASA gives Safety Tips for viewing Total Solar Eclipse in August

 

Written by Dwayne Brown / Laurie Cantillo
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – More than 300 million people in the United States potentially could directly view the Aug. 21 total solar eclipse, and NASA wants everyone who will witness this celestial phenomenon to do so safely.

That Monday, a partial eclipse will be visible in every state. A total solar eclipse, which is when the Moon completely covers the Sun, will occur across 14 states in the continental U.S. along a 70-mile-wide (112-kilometer-wide) swath of the country.

NASA’s New Horizons Team catches glimpse of primitive solar system object

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – A primitive solar system object that’s more than four billion miles (6.5 billion kilometers) away passed in front of a distant star as seen from Earth. Just before midnight Eastern Time Sunday (12:50am local time July 17th), several telescopes deployed by the New Horizons team in a remote part of Argentina were in precisely the right place at the right time to catch its fleeting shadow — an event that’s known as an occultation.

In a matter of seconds, NASA’s New Horizons team captured new data on its elusive target, an ancient Kuiper Belt object known as 2014 MU69. Weary but excited team members succeeded in detecting the spacecraft’s next destination, in what’s being called the most ambitious and challenging ground occultation observation campaign in history.

Ford recalls over 370,000 2015-2017 Transit Vehicles because Driveshaft Coupling may Fail

 

National Highway Traffic Safety Administration - NHTSAWashington, D.C. – National Highway Traffic Safety Administration reports that the Ford Motor Company (Ford) is recalling all 2015-2017 Transit vehicles except 156″ and 178″ wheelbase Chassis Cab and Cut-Away bodies.

In the affected vehicles, the flexible coupling connecting the transmission to the driveshaft may prematurely fail.

2015-2017 Fort Transit Vehicles recalled due to possible Driveshaft Coupling Failure.

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – For the first time in 99 years, a total solar eclipse will occur across the entire continental United States, and NASA is preparing to share this experience of a lifetime on August 21st, 2017.

Viewers around the world will be provided a wealth of images captured before, during, and after the eclipse by 11 spacecraft, at least three NASA aircraft, more than 50 high-altitude balloons, and the astronauts aboard the International Space Station – each offering a unique vantage point for the celestial event.

This image of the moon crossing in front of the sun was captured on Jan. 30, 2014, by NASA's Solar Dynamics Observatory observing an eclipse from its vantage point in space. (NASA)

American Heart Association says Renewed Trend in Movie Tobacco Scenes Disturbing

 

American Heart AssociationWashington, D.C.American Heart Association CEO Nancy Brown issued the following comments today on a new study released by the Centers for Disease Control and Prevention on “Tobacco Use in Top-Grossing Movies — United States, 2010–2016:”

“Based on previous trends, we thought tobacco use in film would soon play its final scene. This latest CDC study indicates a troublesome plot twist.

The Surgeon General has concluded that there is a causal relationship between depictions of smoking in the movies and the initiation of smoking among young persons.

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Vice President Mike Pence thanked employees at NASA’s Kennedy Space Center in Florida for their commitment to America’s continued leadership in the space frontier during a visit to America’s multi-user spaceport on Thursday.

“Let us do what our nation has always done since its very founding and beyond: We’ve pushed the boundaries on frontiers, not just of territory, but of knowledge. We’ve blazed new trails, and we’ve astonished the world as we’ve boldly grasped our future without fear,” the Vice President told employees, government dignitaries and space industry leaders in remarks at the facility’s iconic Vehicle Assembly Building, where the new Space Launch System (SLS) rocket and Orion spacecraft will be prepared ahead of launches to the moon, and eventually to Mars and beyond.
