NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s asteroid sample return spacecraft successfully used Earth’s gravity on Friday to slingshot itself on a path toward the asteroid Bennu, for a rendezvous next August.

At 12:52pm EDT on September 22nd, 2017 the OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer) spacecraft came within 10,711 miles (17,237 km) of Antarctica, just south of Cape Horn, Chile, before following a route north over the Pacific Ocean.

NASA observes Tropical Storm Irma moving North up Florida Peninsula

 

Written by Rob Gutro
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA-NOAA’s Suomi NPP satellite captured night-time look at Hurricane Irma as it weakened to a large tropical storm and the GOES East satellite provided a daytime view as the large storm continued moving north over Florida.

Irma made landfall twice on September 10th, 2017, first in the Florida Keys and then near Naples. The storm has now been downgraded to a tropical storm but could still cause significant impacts over Georgia and Alabama. NASA’s Marshall Space Flight Center in Huntsville, Alabama was under a Tropical Storm Watch on September 11th.

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

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

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.

This is a reconstructed view of Jupiter's northern lights through the filters of the Juno Ultraviolet Imaging Spectrograph instrument on Dec. 11, 2016, as the Juno spacecraft approached Jupiter, passed over its poles, and plunged towards the equator. (NASA/JPL-Caltech/Bertrand Bonfond )

NASA’s InSight Lander to explore interior of Mars

 

Written by Guy Webster / Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Preparation of NASA’s next spacecraft to Mars, InSight, has ramped up this summer, on course for launch next May from Vandenberg Air Force Base in central California — the first interplanetary launch in history from America’s West Coast.

Lockheed Martin Space Systems is assembling and testing the InSight spacecraft in a clean room facility near Denver. “Our team resumed system-level integration and test activities last month,” said Stu Spath, spacecraft program manager at Lockheed Martin. “The lander is completed and instruments have been integrated onto it so that we can complete the final spacecraft testing including acoustics, instrument deployments and thermal balance tests.”

NASA’s Juno Spacecraft to make Seventh Pass over Jupiter

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Juno spacecraft will make its seventh science flyby over Jupiter’s mysterious cloud tops on Friday, September 1st, at 2:49pm PDT (5:49pm EDT and 21:49 UTC).

At the time of perijove (defined as the point in Juno’s orbit when it is closest to the planet’s center), the spacecraft will be about 2,200 miles (3,500 kilometers) above the planet’s cloud tops.

Juno launched on August 5th, 2011, from Cape Canaveral, Florida, and arrived in orbit around Jupiter on July 4th, 2016. During its mission of exploration, Juno soars low over the planet’s cloud tops — as close as about 2,100 miles (3,400 kilometers).

NASA uses resources to help Agencies Provide Hurricane Harvey Response

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA is using its assets and expertise from across the agency, including from NASA’s Jet Propulsion Laboratory in Pasadena, California, to help respond to Hurricane Harvey — now Tropical Storm Harvey — which has been a disaster of unprecedented proportions for those who live and work in Southeast Texas.

With no atmospheric steering mechanism to move the storm once it made landfall, Harvey has been producing rainfall totals measured in feet, rather than inches, presenting exceptional challenges to local, state and federal emergency managers and first responders.

JPL's Advanced Rapid Imaging and Analysis team created this Flood Proxy Map showing areas of Southeast Texas likely flooded from Hurricane Harvey (light blue). The map is derived from radar images from the Japan Aerospace Exploration Agency ALOS-2 PALSAR-2 satellite before and after landfall. (NASA/JPL-Caltech/JAXA/METI/Google Earth)

NASA says Hinode Satellite Captured Powerful Total Solar Eclipse Images, Video

 

Written by Molly Porter
NASA’s Marshall Space Flight Center

NASA - National Aeronautics and Space AdministrationHuntsville, AL – As millions of Americans watched the total solar eclipse that crossed the continental United States August 21st, 2017, the international Hinode solar observation satellite captured its own images of the awe-inspiring natural phenomenon as it orbited the planet. Researchers adapted the still images into a time-lapse video presentation.

Among its many solar research tasks, the satellite’s observation of the eclipse was intended to add new data to ongoing scientific study of the coronal structure in the Sun’s polar region and the mechanism of jets of superheated plasma frequently created there.

NASA’s Juno Spacecraft gets close up look at Jupiter’s Great Red Spot

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Images of Jupiter’s Great Red Spot reveal a tangle of dark, veinous clouds weaving their way through a massive crimson oval. The JunoCam imager aboard NASA’s Juno mission snapped pics of the most iconic feature of the solar system’s largest planetary inhabitant during its Monday (July 10th) flyby.

The images of the Great Red Spot were downlinked from the spacecraft’s memory on Tuesday and placed on the mission’s JunoCam website Wednesday morning.

This enhanced-color image of Jupiter's Great Red Spot was created by citizen scientist Jason Major using data from the JunoCam imager on NASA's Juno spacecraft. (NASA/JPL-Caltech/SwRI/MSSS/Jason Major)
