Washington: NASA for the first time, participated in Norway’s annual oil spill cleanup exercise in the North Sea from June 8 to 11.

Scientists flew a specialised NASA airborne instrument, called the Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR), on NASA’s C-20A piloted research aircraft to monitor a controlled release of oil into the sea, testing the radar’s ability to distinguish between more and less damaging types of oil slicks, NASA said in a statement.

Norway’s Oil on Water exercise has been held annually since the 1980s and in these drills, oil is released onto the ocean and then recovered, giving responders experience with existing cleanup techniques and equipment and a chance to test new technologies.

“This year was special, because we had our own dedicated science experiment in the middle of the training exercise,” said Camilla Brekke, associate professor in the department of physics and technology, at the University of Tromso, Norway.

Brekke invited scientists Cathleen Jones and Ben Holt from NASA’s Jet Propulsion Laboratory, Pasadena, California, to participate in the experiment.

Radars “see” an oil spill, because of a characteristic that the Greek philosopher Aristotle first wrote about 2,500 years ago: pouring oil on water smooths the surface.

The Norwegian exercise released emulsions of differing thicknesses, so that the scientists could have a range of conditions to calibrate the UAVSAR data.

The experiment also tested the instrument’s ability to distinguish between petroleum, and plant-based oil, found in algal blooms.

Norway is one of a few nations worldwide that allow oil to be discharged at sea, to test new cleanup technologies and procedures. (IANS)

The Academy of Television Arts and Sciences (ATAS) has nominated NASA’s Jet Propulsion Laboratory (JPL) for Outstanding Original Interactive Program for its coverage of the Cassini mission’s Grand Finale at Saturn.

The Primetime Emmys will be awarded by the ATAS in Los Angeles on September 17.

The Creative Arts Emmys, which include interactive awards, will be presented during a separate ceremony on September 15 at the Microsoft Theatre in Los Angeles, NASA said in a statement on Friday.

In 2017, after nearly 20 years in space and 13 years revealing the wonders of Saturn, NASA’s Cassini orbiter was running out of fuel. As a final act, Cassini began a whole new mission — its Grand Finale, where it journeyed into the unknown and ended with a spectacular plunge into the planet.

Cassini’s first, daring dive into the unexplored space between the giant planet and its rings kicked off the campaign on April 26 in 2017.

It culminated on September 15, 2017, with live coverage of Cassini’s plunge into Saturn’s atmosphere, with the spacecraft sending back science to the very last second.

JPL created a multi-month digital campaign to celebrate the mission’s science and engineering accomplishments and communicate why the spacecraft must meet its end in the skies of Saturn.

The multi-faceted campaign included regular updates on Twitter, Facebook, Snapchat, Instagram and the Cassini mission website, multiple live social, web and TV broadcasts during which reporter and public questions were answered.

A dramatic short film to communicate the mission’s story and preview its endgame; multiple 360-degree videos, including NASA’s first 360-degree livestream of a mission event from inside JPL mission control.

The Emmy Awards nominations have turned out to be more diverse than last year. Fantasy drama “Game of Thrones” has earned 22 nominations for the coveted Awards, while HBO’s 17-year streak as the most nominated network has been broken by Netflix. (IANS)
