NASA’s GRAIL mission data reveals ‘Ocean of Storms’ region of Earth’s Moon formed from ancient rift valleys

 

Written by DC Agle

NASA - National Aeronautics and Space AdministrationPasadena, CA – Using data from NASA’s Gravity Recovery and Interior Laboratory (GRAIL), mission scientists have solved a lunar mystery almost as old as the moon itself.

Early theories suggested the craggy outline of a region of the moon’s surface known as Oceanus Procellarum, or the Ocean of Storms, was caused by an asteroid impact. If this theory had been correct, the basin it formed would be the largest asteroid impact basin on the moon.

NASA’s Cassini spacecraft observes strange feature in sea on Saturn’s moon Titan

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini spacecraft is monitoring the evolution of a mysterious feature in a large hydrocarbon sea on Saturn’s moon Titan. The feature covers an area of about 100 square miles (260 square kilometers) in Ligeia Mare, one of the largest seas on Titan.

It has now been observed twice by Cassini’s radar experiment, but its appearance changed between the two apparitions.

NASA’s Cold Atom Laboratory to take Atoms to extreme Cold Temperatures on International Space Station

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cold Atom Laboratory (CAL) mission has succeeded in producing a state of matter known as a Bose-Einstein condensate, a key breakthrough for the instrument leading up to its debut on the International Space Station in late 2016.

A Bose-Einstein condensate (BEC) is a collection of atoms in a dilute gas that have been lowered to extremely cold temperatures and all occupy the same quantum state, in which all of the atoms have the same energy levels.

Obama Administration Proposes New Regulations to Expand Important Financial Protections for Military Families

 

United States Department of Defense - DoDWashington, D.C. – The Obama Administration remains committed to supporting our service members and their families.

Yesterday, as part of the Administration’s ongoing commitment, the Department of Defense (DoD) is proposing regulation changes that would reduce predatory lending practices, significantly expand the protections provided to service members, close loopholes in current rules, and help to ensure military families receive the important consumer protections they deserve.

These actions build on the President’s announcement of a voluntary partnership with financial lenders across the country (Fact Sheet) to help deliver important financial and home loan-related protections to our military community. «Read the rest of this article»

NASA’s Mars Curiosity rover takes first drill sample from Mount Sharp

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Curiosity Mars rover has collected its first taste of the layered mountain whose scientific allure drew the mission to choose this part of Mars as a landing site.

Late Wednesday, September 24th, the rover’s hammering drill chewed about 2.6 inches (6.7 centimeters) deep into a basal-layer outcrop on Mount Sharp and collected a powdered-rock sample. Data and images received early Thursday at NASA’s Jet Propulsion Laboratory, Pasadena, California, confirmed success of this operation. The powder collected by the drilling is temporarily held within the sample-handling mechanism on the rover’s arm.

NASA to send additional Earth Science Instruments to International Space Station

 

Written by Dr. Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The International Space Station has been called a stepping stone to other worlds.

NASA hasn’t forgotten, however, that the behemoth space station is also on the doorstep of Earth.

“We’re seeing the space station come into its own as an Earth-observing platform,” says Julie Robinson, chief scientist for the International Space Station Program. “It has a different orbit than other Earth-observing satellites. It’s closer to Earth, and it sees Earth at different times of day with a different schedule.”

Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Arctic sea ice coverage continued its below-average trend this year as the ice declined to its annual minimum on September 17th, according to the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado, Boulder.

“Arctic sea ice coverage in 2014 is the sixth lowest recorded since 1978,” said Walter Meier, a research scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft enters Mars Orbit

 

Written by Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft successfully entered Mars’ orbit at 10:24pm EDT Sunday, September 21st, where it now will prepare to study the Red Planet’s upper atmosphere as never done before. MAVEN is the first spacecraft dedicated to exploring the tenuous upper atmosphere of Mars.

“As the first orbiter dedicated to studying Mars’ upper atmosphere, MAVEN will greatly improve our understanding of the history of the Martian atmosphere, how the climate has changed over time, and how that has influenced the evolution of the surface and the potential habitability of the planet,” said NASA Administrator Charles Bolden. “It also will better inform a future mission to send humans to the Red Planet in the 2030s.”

U.S. Special Operations CommandWashington, D.C. – To combat the demands on the nation’s special operations forces, U.S. Special Operations Command has made its Preservation of the Force and Family initiative a priority, the program’s director said September 17th.

Speaking at the Defense Centers of Excellence for Psychological Health and Resilience Summit in Falls Church, Virginia, Navy Capt. Thomas Chaby said the program for the joint command’s 67,000 soldiers, sailors, airmen and Marines centers on prevention by building resilience and giving troops the tools and strategies they need to navigate combat’s challenges. «Read the rest of this article»
