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.”

DoD News, Defense Media Activity

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»

NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft ready to enter Mars orbit

 

Written by Izumi Hansen and Elizabeth Zubritsky
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft is nearing its scheduled September 21st insertion into Martian orbit after completing a 10-month interplanetary journey of 442 million miles (711 million kilometers).

Flight Controllers at Lockheed Martin Space Systems in Littleton, Colorado, will be responsible for the health and safety of the spacecraft throughout the process. The spacecraft’s mission timeline will place the spacecraft in orbit at approximately 6:50pm PDT (9:50pm EDT).

NASA's MAVEN spacecraft is quickly approaching Mars on a mission to study its upper atmosphere. When it arrives on September 21, 2014, MAVEN's winding journey from Earth will culminate with a dramatic engine burn, pulling the spacecraft into an elliptical orbit.

NASA - National Aeronautics and Space AdministrationWashington, D.C. – On Wednesday morning, October 8th, not long before sunrise, the bright full Moon over North America will turn a lovely shade of celestial red. It’s a lunar eclipse—visible from all parts of the USA.

“It promises to be a stunning sight, even from the most light polluted cities,” says NASA’s longtime eclipse expert Fred Espenak. “I encourage everyone, especially families with curious children, to go out and enjoy the event.”

NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) discovers source of Intense Gamma Rays

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Our Milky Way galaxy is littered with the still-sizzling remains of exploded stars.

When the most massive stars explode as supernovas, they don’t fade into the night, but sometimes glow ferociously with high-energy gamma rays. What powers these energetic stellar remains?

NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, is helping to untangle the mystery. The observatory’s high-energy X-ray eyes were able to peer into a particular site of powerful gamma rays and confirm the source: A spinning, dead star called a pulsar.

NASA’s Dawn Spacecraft out of Safe Mode and back to Normal Operational State

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The Dawn spacecraft has resumed normal ion thrusting after the thrusting unexpectedly stopped and the spacecraft entered safe mode on September 11th. That anomaly occurred shortly before a planned communication with NASA’s Deep Space Network that morning. The spacecraft was not performing any special activities at the time.

Engineers immediately began working to restore the spacecraft to its normal operational state. The team determined the source of the problems, corrected them, and then resumed normal ion thrusting on Monday night, September 15th.

NASA - National Aeronautics and Space AdministrationPasadena, CA – The European Space Agency’s Rosetta’s lander, Philae, will target Site J, an intriguing region on comet 67P/Churyumov-Gerasimenko that offers unique scientific potential, with hints of activity nearby, and minimum risk to the lander compared to the other candidate sites.

The 220-pound (100-kilogram) lander is scheduled to reach the surface on November 11th, where it will perform in-depth measurements to characterize the nucleus. Rosetta is an international mission spearheaded by the European Space Agency with support and instruments provided by NASA.
