  • NASA’s new instrument can measure Sun’s incoming energy
  • The instrument is called Total and Spectral Solar Irradiance Sensor (TSIS-1)
  • This can help bring in an energy revolution in future

To continue long-term measurements of the Sun’s incoming energy, NASA has powered on a new instrument installed on the International Space Station (ISS).

Sun
Solar energy is one of the biggest energy sources in the world.

The instrument, Total and Spectral solar Irradiance Sensor (TSIS-1), became fully operational with all instruments collecting science data as of this March, NASA said.

“TSIS-1 extends a long data record that helps us understand the Sun’s influence on Earth’s radiation budget, ozone layer, atmospheric circulation, and ecosystems, and the effects that solar variability has on the Earth system and climate change,” said Dong Wu, TSIS-1 project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. TSIS-1 studies the total amount of light energy emitted by the Sun using the Total Irradiance Monitor, one of two sensors onboard.

This sensor’s data will give scientists a better understanding of Earth’s primary energy supply and provide information to help improve models simulating the planet’s climate.

The second onboard sensor, called the Spectral Irradiance Monitor, measures how the Sun’s energy is distributed over the ultraviolet, visible and infrared regions of light. Measuring the distribution of the Sun’s energy is important because each wavelength of light interacts with the Earth’s atmosphere differently.

For instance, spectral irradiance measurements of the Sun’s ultraviolet radiation are critical to understanding the ozone layer — Earth’s natural sunscreen that protects life from harmful radiation.

“All systems are operating within their expected ranges,” said Peter Pilewskie, TSIS-1 lead scientist at the University of Colorado Laboratory for Atmospheric and Space Physics in the US. IANS

Emmy Awards 2018: NASA Nominated for Stunning Footage of Cassini voyage to Saturn

The Emmy Awards nominations have turned out to be more diverse than last year

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.

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)
