Washington, D.C. – This Saturday at 5:51am PDT, (7:51am CDT, 12:51 UTC) NASA’s Juno spacecraft will get closer to the cloud tops of Jupiter than at any other time during its prime mission.
At the moment of closest approach, Juno will be about 2,600 miles (4,200 kilometers) above Jupiter’s swirling clouds and traveling at 130,000 mph (208,000 kilometers per hour) with respect to the planet. There are 35 more close flybys of Jupiter scheduled during its prime mission (scheduled to end in February of 2018).
NASA’s WISE Explorer and Fermi Gamma-ray Space Telescope discover infrared/gamma ray connection to Blazars
Written by Elizabeth Landau
Pasadena, CA – Astronomers studying distant galaxies powered by monster black holes have uncovered an unexpected link between two very different wavelengths of the light they emit, the mid-infrared and gamma rays.
The discovery, which was accomplished by comparing data from NASA’s Wide-field Infrared Survey Explorer (WISE) and Fermi Gamma-ray Space Telescope, has enabled the researchers to uncover dozens of new blazar candidates.

Pasadena, CA – Seasonal dark streaks on Mars that have become one of the hottest topics in interplanetary research don’t hold much water, according to the latest findings from a NASA spacecraft orbiting Mars.
The new results from NASA’s Mars Odyssey mission rely on ground temperature, measured by infrared imaging using the spacecraft’s Thermal Emission Imaging System (THEMIS). They do not contradict last year’s identification of hydrated salt at these flows, which since their 2011 discovery have been regarded as possible markers for the presence of liquid water on modern Mars.

Pasadena, CA – Each year, NASA funds a handful of futuristic concepts to push forward the boundaries of space exploration. These early-stage proposals are selected with the hope of developing new ideas into realistic proofs-of-concept.
From August 23rd to 25th, the NASA Innovative Advanced Concepts (NIAC) symposium will host presentations on 28 proposals, including five from NASA’s Jet Propulsion Laboratory, Pasadena, California.

Greenbelt, MD – On August 21st, 2016, contact was reestablished with one of NASA’s Solar Terrestrial Relations Observatories, known as the STEREO-B spacecraft, after communications were lost on October 1st, 2014.
Over 22 months, the STEREO team has worked to attempt contact with the spacecraft. Most recently, they have attempted a monthly recovery operation using NASA’s Deep Space Network, or DSN, which tracks and communicates with missions throughout space.
NASA’s Stennis Space Center
Bay St. Louis, MS – NASA engineers successfully conducted a development test of the RS-25 rocket engine Thursday, August 18th at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. The RS-25 will help power the core stage of the agency’s new Space Launch System (SLS) rocket for the journey to Mars.
A variety of NASA officials and contractor representatives, as well as social and traditional media members, gathered to watch the 420-second test of RS-25 engine No. 0528. NASA is developing the SLS to send humans further into deep space than they have ever traveled, including on the journey to Mars.

Pasadena, CA – Eroded mesas and buttes reminiscent of the U.S. Southwest shape part of the horizon in the latest 360-degree color panorama from NASA’s Curiosity Mars rover.
The rover used its Mast Camera (Mastcam) to capture dozens of component images of this scene on August 5th, 2016, four years after Curiosity’s landing inside Gale Crater.
The visual drama of Murray Buttes along Curiosity’s planned route up lower Mount Sharp was anticipated when the site was informally named nearly three years ago to honor Caltech planetary scientist Bruce Murray (1931-2013), a former director of NASA’s Jet Propulsion Laboratory, Pasadena, California. JPL manages the Curiosity mission for NASA.

Pasadena, CA – On August 16th, 2016, at around 10:30am, a brush fire ignited in the Cajon Pass east of Los Angeles, just to the west of Interstate 15. Within a matter of hours, extreme temperatures, high winds and low humidity allowed the fire to spread rapidly, burning through brush left tinder-dry by years of drought.
By August 17th, the fire had expanded dramatically, and firefighters continue to battle to save homes and evacuate residents.

Edwards, CA – Some interns get coffee. Others might make copies. Not at NASA Armstrong Flight Research Center in California, where a group of students successfully flew a prototype of an aircraft that could one day fly in the Martian atmosphere and send its findings back to Earth.
Called the Preliminary Research Aerodynamic Design to Land on Mars, or Prandtl-M, the small, remotely piloted glider aircraft flew August 11th at Armstrong. It continues an effort that began last year with a mostly different group of students.
NASA’s Goddard Space Flight Center
Greenbelt, MD – July 2016 was the warmest July in 136 years of modern record-keeping, according to a monthly analysis of global temperatures by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York.
Because the seasonal temperature cycle peaks in July, it means July 2016 also was warmer than any other month on record. July 2016’s temperature was a statistically small 0.1 degrees Celsius warmer than previous warm Julys in 2015, 2011 and 2009.
