NASA - National Aeronautics and Space AdministrationWashington, D.C. – The engineers and scientists working on NASA’s Juno mission have been busying themselves, getting their newly arrived Jupiter orbiter ready for operations around the largest planetary inhabitant in the solar system.

Juno successfully entered Jupiter’s orbit during a 35-minute engine burn on Monday, July 4th. Confirmation that the burn had completed was received on Earth at 8:53pm. PDT (11:53pm EDT) that evening.

NASA studies Mars Canyons for signs of liquid water

 

Written by Guy Webster

NASA - National Aeronautics and Space AdministrationPasadena, CA – Puzzles persist about possible water at seasonally dark streaks on Martian slopes, according to a new study of thousands of such features in the Red Planet’s largest canyon system.

The study published today investigated thousands of these warm-season features in the Valles Marineris region near Mars’ equator. Some of the sites displaying the seasonal flows are canyon ridges and isolated peaks, ground shapes that make it hard to explain the streaks as resulting from underground water directly reaching the surface.

Blue dots on this map indicate sites of recurring slope lineae (RSL) in part of the Valles Marineris canyon network on Mars. RSL are seasonal dark streaks that may be indicators of liquid water. The area mapped here has the highest density of known RSL on Mars. (NASA/JPL-Caltech/Univ. of Arizona)

NASA - National Aeronautics and Space AdministrationPasadena, CA – The team operating NASA’s Curiosity Mars rover is taking steps to return the rover to full activity following a precautionary stand-down over the Fourth of July weekend.

Curiosity is now communicating with ground controllers and is stable. The rover put itself into safe mode on July 2nd, ceasing most activities other than keeping itself healthy and following a prescribed sequence for resuming communications.

Congressman Marsha Blackburn

7th District of Tennessee

U.S. Congress

Washington, D.C. – Congressman Marsha Blackburn (R-TN), Vice Chairman of the House Energy and Commerce Committee, today released the following statement after House passage of the Helping Families in Mental Health Crisis Act of 2015 (H.R. 2646), the most significant reform to our nation’s mental health programs in decades.

“While one in five Americans will face mental illness, the current state of mental health care in our country has left many behind. Four million Americans with serious mental illness receive no treatment at all.

FBI Director James B. Comey’s statement on the Investigation of Secretary Hillary Clinton’s Use of a Personal E-Mail System

 

Remarks prepared for delivery at press briefing.

FBIWashington, D.C. – Good morning. I’m here to give you an update on the FBI’s investigation of Secretary Clinton’s use of a personal e-mail system during her time as Secretary of State.

After a tremendous amount of work over the last year, the FBI is completing its investigation and referring the case to the Department of Justice for a prosecutive decision. What I would like to do today is tell you three things: what we did; what we found; and what we are recommending to the Department of Justice.

This will be an unusual statement in at least a couple ways. First, I am going to include more detail about our process than I ordinarily would, because I think the American people deserve those details in a case of intense public interest.

NASA’s Juno Spacecraft prepares for Jupiter Orbit Insertion

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – After almost five years and 1.7 billion million miles (2.7 billion kilometers), NASA’s Juno mission is about to enter into orbit around the biggest planetary inhabitant in our solar system — Jupiter. Approaching the massive planet from above, Juno will be within 300,000 miles of Jupiter by 2:14pm PDT (5:14pm EDT).

A minute later, Juno will cross the orbit of Jupiter’s innermost Galilean moon (Io), at 2:15pm PDT (5:15pm EDT). Juno closes the distance between it and the gas-giant world to 200,000 miles (322,000 kilometers) by 4:17pm PDT (7:17pm EDT) and is only 100,000 miles (161,000 kilometers) away by 6:03pm PDT (9:03pm EDT).

NASA's Juno spacecraft obtained this color view on June 28, 2016, at a distance of 3.9 million miles (6.2 million kilometers) from Jupiter. (NASA/JPL-Caltech/SwRI/MSSS)

The History of Independence Day

 

Library of CongressWashington, D.C. – The Second Continental Congress announced the colonies’ separation from Great Britain by unanimously adopting the Declaration of Independence, on July 4th, 1776.

The Constitution provides the legal and governmental framework for the United States, however, the Declaration, with its eloquent assertion “all Men are created equal,” is equally beloved by the American people.

Philadelphians marked the first anniversary of American independence with a spontaneous celebration, which is described in a letter by John Adams to Abigail Adams.

NASA’s Dawn spacecraft finishes objectives at Dwarf Planet Ceres, completes mission

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – On June 30th, just in time for the global celebration known as Asteroid Day, NASA’s Dawn spacecraft completes its primary mission. The mission exceeded all expectations originally set for its exploration of protoplanet Vesta and dwarf planet Ceres.

The historic mission is the first to orbit two extraterrestrial solar system targets, and the first to orbit any object in the main asteroid belt, between Mars and Jupiter. On March 6th, 2015, Dawn also became the first spacecraft to enter orbit around a dwarf planet.

Marsha Blackburn Introduces Plan Verification and Fairness Act

 

Increases transparency and saves taxpayer dollars

U.S. Congress

Washington, D.C. – Congressman Marsha Blackburn (R-TN) today introduced H.R. 8934, the Plan Verification and Fairness Act, legislation that would ensure proper verification is required prior to receiving healthcare coverage under exchange special enrollment periods (SEPs).

Under current law, individuals aren’t required to prove that they qualify for these special enrollment periods (SEPs) before the plan takes effect, leading to higher costs for patients playing by the rules and risk imbalance within exchange markets.

NASA’s Juno Spacecraft takes a look at Jupiter’s Magnetic Field

 

Written by Sarah Schlieder
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s Juno spacecraft will make its long anticipated arrival at Jupiter on July 4th. Coming face-to-face with the gas giant, Juno will begin to unravel some of the greatest mysteries surrounding our solar system’s largest planet, including the origin of its massive magnetosphere.

Magnetospheres are the result of a collision between a planet’s intrinsic magnetic field and the supersonic solar wind. Jupiter’s magnetosphere — the volume carved out in the solar wind where the planet’s magnetic field dominates –extends up to nearly 2 million miles (3 million kilometers).

Scientists will use the twin magnetometers aboard NASA's Juno spacecraft to gain a better understanding about how Jupiter's magnetic field is generated. (NASA Goddard Space Flight Center)
