Washington, April 13, 2017: NASA has released its latest global maps of Earth at night, providing the “clearest yet composite” view of the patterns of human settlement across our planet.

Satellite images of Earth at night — often referred to as “night lights” — have been a tool for fundamental research for nearly 25 years.

They have provided a broad, beautiful picture, showing how humans have shaped the planet and lit up the darkness.

By studying Earth at night, researchers can investigate how cities expand, monitor light intensity to estimate energy use and economic activity, and aid in disaster response.

These maps are generally produced every decade or so. But NASA’s new global map of Earth at night, as observed in 2016, has been released this week just five years after the such map was released in 2012.

A research team led by Earth scientist Miguel Roman of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, plans to find out this year what would happen if night lights imagery could be updated yearly, monthly or even daily.

In the years since the 2011 launch of the NASA-National Oceanic and Atmospheric Administration Suomi National Polar-orbiting Partnership (NPP) satellite, Roman and colleagues have been analysing night lights data and developing new software and algorithms to make night lights imagery clearer, more accurate and readily available.

They are now on the verge of providing daily, high-definition views of Earth at night, and are targeting the release of such data to the science community later this year, NASA said. (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)
