NASA’s Juno mission observes Jupiter’s Auroras acting differently than expected

 

Written by DC Agle

NASA - National Aeronautics and Space AdministrationPasadena, CA – Scientists on NASA’s Juno mission have observed massive amounts of energy swirling over Jupiter’s polar regions that contribute to the giant planet’s powerful auroras – only not in ways the researchers expected.

Examining data collected by the ultraviolet spectrograph and energetic-particle detector instruments aboard the Jupiter-orbiting Juno spacecraft, a team led by Barry Mauk of the Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland, observed signatures of powerful electric potentials, aligned with Jupiter’s magnetic field, that accelerate electrons toward the Jovian atmosphere at energies up to 400,000 electron volts.

Fort Campbell, KY – The preparation for this deployment saw 2-327th “No Slack” Soldiers and leaders surmount innumerable hurdles to successfully plan and execute the movement to South Africa. The burden of the planning fell to No Slack’s S-4 section, led by Capt. Clay Drnek, 2-327th battalion supply officer.

“This was a lot for such a small unit to handle,” said Drnek, a native of Eau Claire Pennsylvania.

U.S. Army

U.S. ArmyFort Campbell, KY – Just four months after the last Soldiers from the 2nd Brigade Combat Team, 101st Airborne Division (2/101 Air Assault) returned home from an advise and assist mission in Iraq, the 2/101 “Strike” Brigade is gearing up for a new mission as they bring a light infantry perspective to integrating and evolving communications systems during the Army’s signature operational network exercise.

Known as the Network Integration Evaluation (NIE) and taking place at Fort Bliss, Texas, in July, the exercise is designed to help the Army keep pace with rapid advances in communications technologies and deliver integrated network and mission command capabilities to support readiness.

NASA’s Earth Observing 1 spacecraft’s A.I system orders Volcano data collection

 

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – One of our planet’s few exposed lava lakes is changing, and artificial intelligence is helping NASA understand how.

On January 21st, a fissure opened at the top of Ethiopia’s Erta Ale volcano — one of the few in the world with an active lava lake in its caldera. Volcanologists sent out requests for NASA’s Earth Observing 1 (EO-1) spacecraft to image the eruption, which was large enough to begin reshaping the volcano’s summit.

As it turned out, that spacecraft was already busy collecting data of the lava lake.

Artificial intelligence onboard NASA's Earth Observing 1 (EO-1) spacecraft assisted in imaging an eruption at Erta'Ale volcano, Ethiopia, from an altitude of 438 miles (705 kilometers). The observation was scheduled autonomously via the Volcano Sensor Web, which was alerted to this new activity by data from another spacecraft. (NASA/JPL/EO-1 Mission/GSFC/Ashley Davies)

NASA prepares Satellites for alignment of Planets and Stars

 

Written by Mara Johnson-Groh
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – The movements of the stars and the planets have almost no impact on life on Earth, but a few times per year, the alignment of celestial bodies has a visible effect.

One of these geometric events — the spring equinox — is just around the corner, and another major alignment — a total solar eclipse — will be visible across America on August 21st, with a fleet of NASA satellites viewing it from space and providing images of the event.

To understand the basics of celestial alignments, here is information on equinoxes, solstices, full moons, eclipses and transits:

During a transit, a planet passes in between us and the star it orbits. This method is commonly used to find new exoplanets in our galaxy. (NASA's Goddard Space Flight Center/Genna Duberstein)

NASA’s Aqua Satellite discovers Ammonia Hotspots around the World

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The first global, long-term satellite study of airborne ammonia gas has revealed “hotspots” of the pollutant over four of the world’s most productive agricultural regions.

The results of the study, conducted using data from NASA’s Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua satellite, could inform the development of strategies to control pollution from ammonia and ammonia byproducts in Earth’s agricultural areas.

A University of Maryland-led team discovered steadily increasing ammonia concentrations from 2002 to 2016 over agricultural centers in the United States, Europe, China and India. Increased concentrations of atmospheric ammonia are linked to poor air and water quality.

Global atmospheric ammonia trends measured from space from 2002 to 2016. Hot colors represent increases from a combination of increased fertilizer application, reduced scavenging by acid aerosols and climate warming. Cool colors show decreases due to reduced agricultural burning or fewer wildfires. (Juying Warner/GRL)
