NASA Scientists lead International Team in Global Asteroid Tracking Test

NASA - National Aeronautics and Space AdministrationWashington, D.C. – An international team of astronomers led by NASA scientists successfully completed the first global exercise using a real asteroid to test global response capabilities.

Planning for the so-called “TC4 Observation Campaign” started in April, under the sponsorship of NASA’s Planetary Defense Coordination Office. The exercise commenced in earnest in late July, when the European Southern Observatory’s Very Large Telescope recovered the asteroid. The finale was a close approach to Earth in mid-October.

2012 TC4's heliocentric orbit has changed due to the 2012 and 2017 close encounters with Earth. The cyan color shows the trajectory before the 2012 flyby, the magenta shows the trajectory after the 2012 flyby, and yellow shows the trajectory after the 2017 flyby. The orbital changes were primarily in semi-major axis and eccentricity, although there were also slight changes in the inclination. (NASA/JPL-Caltech)

NASA reports Gamma-ray Telescopes discover concentration of Energy in Center of Milky Way

 

Written by Francis Reddy
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – A combined analysis of data from NASA’s Fermi Gamma-ray Space Telescope and the High Energy Stereoscopic System (H.E.S.S.), a ground-based observatory in Namibia, suggests the center of our Milky Way contains a “trap” that concentrates some of the highest-energy cosmic rays, among the fastest particles in the galaxy.

“Our results suggest that most of the cosmic rays populating the innermost region of our galaxy, and especially the most energetic ones, are produced in active regions beyond the galactic center and later slowed there through interactions with gas clouds,” said lead author Daniele Gaggero at the University of Amsterdam. “Those interactions produce much of the gamma-ray emission observed by Fermi and H.E.S.S.”

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.

Southern White Rhinos Now Roaming at Nashville Zoo

 

Nashville ZooNashville, TN – Nashville Zoo is proud to announce the introduction of Southern white rhinoceros to our animal family. Four young females are now roaming in the Zoo’s former elephant exhibit.

“This is the first time we are able to bring rhinos to Nashville,” said Zoo President Rick Schwartz. “We had to make several modifications to the former elephant habitat and barn in order to properly care for rhinos. The end result is exceptional and we can’t wait to show it to our guests.”

The four captive born white rhinos came from a reserve in South Africa and are slowly adjusting to the new sights, sounds, and smells that come with their new home here in Nashville.

NASA’s New Horizons spacecraft’s next target already revealing surprises

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s New Horizons spacecraft doesn’t zoom past its next science target until New Year’s Day 2019, but the Kuiper Belt object, known as 2014 MU69, is already revealing surprises.

Scientists have been sifting through data gathered from observing the object’s quick pass in front of a star – an astronomical event known as an occultation – on June 3rd.

More than 50 mission team members and collaborators set up telescopes across South Africa and Argentina, along a predicted track of the narrow shadow of MU69 that the occultation would create on Earth’s surface, aiming to catch a two-second glimpse of the object’s shadow as it raced across the Earth.

Four members of the New Horizons’ South African observation team scan the sky while waiting for the start of the 2014 MU69 occultation, early on the morning of June 3rd, 2017. (NASA/JHUAPL/SwRI/Henry Throop)

NASA reports a strong, growing El Niño head to United States

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The current strong El Niño brewing in the Pacific Ocean shows no signs of waning, as seen in the latest satellite image from the U.S./European Ocean Surface Topography Mission (OSTM)/Jason-2 mission.

El Niño 2015 has already created weather chaos around the world. Over the next few months, forecasters expect the United States to feel its impacts as well.

The latest Jason-2 image bears a striking resemblance to one from December 1997, by Jason-2’s predecessor, the NASA/Centre National d’Etudes Spatiales (CNES) Topex/Poseidon mission, during the last large El Niño event. Both reflect the classic pattern of a fully developed El Niño. The images can be viewed at:

The latest satellite image of Pacific sea surface heights from Jason-2 (left) differs slightly from one 18 years ago from Topex/Poseidon (right). In Dec. 1997, sea surface height was more intense and peaked in November. This year the area of high sea levels is less intense but considerably broader. (NASA/JPL-Caltech)
