Each of us can make a positive difference stepping up & doing our best / Becoming Planet Citizens
- Time for Planet Citizen Action
From its origins, NASA has studied our planet in novel ways, using ingenious tools to study physical processes at work—from beneath the crust to the edge of the atmosphere. We look at it in macrocosm and microcosm, from the flow of one mountain stream to the flow of jet streams. Most of all, we look at Earth as a system, examining the cycles and processes—the water cycle, the carbon cycle, ocean circulation, the movement of heat—that interact and influence each other in a complex, dynamic dance across seasons and decades.
For all of the dynamism and detail we can observe from orbit, sometimes it is worth stepping back and simply admiring Earth. It is a beautiful, awe-inspiring place, and it is the only world most of us will ever know.
Of all celestial bodies within reach or view, as far as we can see, out to the edge, the most wonderful and marvelous and mysterious is turning out to be our own planet earth. There is nothing to match it anywhere, not yet anyway. — Lewis Thomas
- GreenPolicy360's in on the Mission
GreenPolicy360 stepped up as Planet Citizens to assist the NASA/NOAA team to deliver the first DSCOVR/EPIC data and imagery
NASA Goddard communications to us, including this March 11th correspondence with GreenPolicy360, discussed calibrated data products to come from DSCOVR...
Ten different wavelengths of EPIC data is now being served from the Atmospheric Science Data Center (ASDC) at Langley.
Welcome to Daily Views of Our Home Planet
The DSCOVR satellite with its EPIC cam, PlasMag & NISTAR instrument package... is on a million mile journey and in approx four months, DSCOVR will "light up", be tested, and begin delivering data to Earth. In its historic mission, DSCOVR and its EPIC imaging system will begin sending near real-time images of the whole Earth... it has been many years since whole Earth images have been readily available...
An Earth Point of View
From Space, In Space, an Astronaut's Overview
- Dr. Sanjay Gupta speaks to astronaut Scott Kelly about his record-setting mission in space.
- Scott Kelly speaks of a "fragile"... "thin veil" of the atmosphere around the Earth and how we have to protect it -- #ThinBlueLayer #Earth360

GreenPolicy360 tweeted @AstroTerry "yes we wish we could see what you are seeing ;-)" and then we updated our #OverviewEffect page w/ the astronaut's #Earth appreciation from the #ISS that he wishes we could see what he sees
Amazing time-lapse videos from astro-photographs of Earth
- Watch Earth roll by through the perspective of ESA astronaut Alexander Gerst in this six-minute timelapse video from space.
Combining 12 500 images taken by Alexander during his six-month Blue Dot mission on the International Space Station this Ultra High Definition video shows the best our beautiful planet has to offer.
Auroras, sunrises, clouds, stars, oceans, the Milky Way, the International Space Station, lightning, cities at night, spacecraft -- and the thin band of atmosphere that protects us from space.
Astronauts on the way home
Three of our favorite astronauts return to Earth from the International Space Station.
We've been receiving many absolutely beautiful photos from them with their expressions of awe.
Our "whole Earth" and a "narrow", "thin layer of atmosphere."
How amazing it is to have 'tweets' and 'blogging' from an int'l 'bird' flying high over our blue planet.
"Look at how thin our atmosphere is. This is all there is between humankind and deadly space." 
We are just beginning to geo-monitor our thin atmosphere and biosphere from space...
"Here we are on the Space Station basking in blue Earthshine as ...
the rising sun pierces our razor-thin atmosphere to cover ... us with blue light.
I’ll never forget this place ... seeing this makes the heart soar and the soul sing."
-- Astronaut Wheelock
From Space, Watching the Earth Breathe
1st light! OCO-2 announces we have data!
The newly launched Orbiting Carbon Observatory is now at the front of the international “Afternoon Constellation,” the “A-Train” of Earth-observing satellites in orbit. Their synchronized collection of data is a first and advances #earthmonitoring with a qualitative, quantum leap. Go we go!! Orbiting Carbon Observatory And while the A Train rolls on in the sky, maybe you'd like to listen to old but always good Duke Ellington's A Train ;-)
The image [spectra image below] shows some of the first data taken by OCO-2 as it flew over Papua-New Guinea forests on August 6, 2014. Each plot shows three different spectra, or wavelength, observed by the satellite’s spectrometers: 760 nanometers (atmospheric oxygen), 1610 nanometers (carbon dioxide), and 2060 nanometers (carbon dioxide).
As OCO-2 flies over Earth’s sunlit hemisphere, each spectrometer collects a frame three times per second (a total of about 9,000 frames from each orbit). Each frame is divided into eight spectra that record the amount of molecular oxygen or carbon dioxide over adjacent ground footprints, each of which is about 2.25 kilometers (1.39 miles) long and a few hundred meters wide. When displayed as an image, the spectra appear like bar codes. The dark lines indicate absorption by molecular oxygen or carbon dioxide.
“The initial data from OCO-2 appear exactly as expected; the spectra lines are well resolved, sharp, and deep,” says OCO-2 chief architect Randy Pollock of NASA’s Jet Propulsion Laboratory.
“We still have a lot of work to do to go from having a working instrument to having a well-calibrated and scientifically useful instrument, but this was an amazingly important milestone.”
To put the spectra in context, the natural-color image here shows the cloudy, forested scene below OCO-2 just minutes after it collected its data.
The color image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite in the A Train orbit.

EarthPOV's point of view re: AGW/Anthropogenic Global Warming...
While the extent of the climate crisis is debated, the data of science continues to be gathered by NASA, NOAA, ESA, and myriad educational and research organizations.
New Space satellites, mapping and monitoring, reporting results, modeling, assembling statistics and projections, recording temperature trends globally and locally, are doing the essential work of #EarthSystemScience.
EarthPOV takes a simple environmental science position:
Cleaner air and water and healthy foods are goals to pursue with clear vision. Reducing pollution is necessary. A healthy environment is vital and alive.
Supporting ongoing science is needed to 'measure and manage' these goals, to protect and support #PlanetEarth in sustainable, productive, life enhancing ways.
