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)

US Senators Want NASA To Extend The ISS Life Until At Least 2028

The aim was to save mony so that more resources could invested into deep space exploration of the Moon and eventually Mars.

NASA should extend the life of the International Space Station (ISS) until at least 2028, two US Senators said in a hearing to examine the future of the orbiting laboratory.

Senator Ted Cruz of Texas who is the Chairman of the Subcommittee on Space, Science, and Competitiveness convened the hearing on Wednesday, which was the first in a series of two hearings to examine the role of the space station.

In its 2019 budget request, the Donald Trump administration proposed ending direct government funding for the ISS by 2025, Florida Today, part of the USA Today network, reported on Wednesday.

“We’ve got this platform up there (worth) north of $100 billion, and it’s there,” Senator Bill Nelson of Florida, ranking member on the Subcommittee on Space, Science and Competitiveness, was quoted as saying.

“Abandoning this incredible orbiting laboratory where they are doing research, when we are on the cusp of a new era of space exploration, would be irresponsible at best and probably disastrous,” Nelson added.

The NASA Transition Authorization Act of 2017 directed NASA to develop a plan to transition ISS from the current regime that relies heavily on NASA sponsorship to a regime where NASA could be one of many customers of a low-Earth orbit (LEO) non-governmental human space flight enterprise.

The aim was to save mony so that more resources could invested into deep space exploration of the Moon and eventually Mars.

The space agency’s internal watchdog on Wednesday, however, said that private companies are unlikely to take on the more than $1 billion annual cost to run the International Space Station by 2025 as NASA hopes.

The report from NASA Inspector General provided a closing argument against the Trump administration’s proposal to privatise or abandon the orbiting laboratory so soon, the US senators said, according to the Florida Today report.

“The defence rests,” quipped Senator Cruz of Texas. (IANS)
