Here’s Hoping Earth Imagery Isn’t Too Routine to Inspire!!!


Here’s Hoping Earth Imagery Isn’t Too Routine to Inspire!!!


Updated, 9:58 p.m. | Much has been written about the remarkable achievements of NASA astronaut Scott Kelly and his Russian counterpart, cosmonaut Mikhail Kornienko, during their (340-day) Year in Space mission aboard the International Space Station. Daniel Victor had a fine overview on Tuesday and make sure to revisit Kenneth Chang’s fascinating package on Kelly and the long mission, in which, as he notes, Kelly and Kornienko experienced 10,880 sunrises* and sunsets in those 340 days.

This post is simply a brief note of thanks to Kelly, in particular, for sharing 1,000 images of Earth shot from the space station and posted on Twitter and Instagram using the #yearinspace hashtag.
You can sift the entire batch at WindowsOnEarth.org, a website featuring photography by astronauts aboard the International Space Station. In a related contest, starting on March 7 on Facebook, you can make the case for your favorites. (The primary source for such images is NASA’s Gateway to Astronaut Photography of Earth.*)
Given how such imagery has become so commonplace, I found myself wondering this week whether such views of Earth have retained the ability to inspire and meaningfully engage people back on the surface with the reality that all of our triumphs and tragedies, dreams and defeats are limited to a tiny “pale blue dot,” as Carl Sagan so eloquently put things two decades ago (it was this phrase that inspired the name of this blog back in 2007).
I’d like to hear from you on this question. I especially hope to hear from young people who’ve grown up with an unremarkable top-down view of the aurora borealis.
Here’s the answer I got from Dan Barstow, the education manager for the International Space Station National Lab, who also curates an online collection of space station photography*:
I’ve been involved in Earth and space science education for years.  And there’s no question. These images continue to inspire and engage. They are masterpieces of science and art.  And like most art, their power is emotional. They engage, inspire and most importantly, help us see the Earth as a whole planet.
I’ve reviewed hundreds of thousands of images, and shared them through the web, through public presentations, in art galleries, and in educational lessons. These photos never fail to inspire “wow” moments.
I remember asking astronaut Karen Nyberg how her photography changed over her six months in space.  She said that at first she focused on the science and planetary geography — weather events, volcanoes, retreating glaciers, the aurora, cities at night…. But then she began to focus more on the sheer beauty of Earth, the artistic side. And she certainly took some wonderful evocative photos.
The astronauts take hundreds of pictures every day.  Many are tasked by scientists — a daily list of priority targets. But most are taken directly from the astronauts’ hearts and souls. “Oh wow! Look at that.” Click.  “And that!” Click.
Remember, this is hand-held photography. They use Nikon D4 digital cameras with a whole range of lenses. And just like anyone traveling, the camera helps them engage with the views and share them with the world.
And that is the real power of these photos. They go right from the astronaut’s heart to our own. They inspire something deep within all of us — a love for our home planet. The astronauts are our human eyes in space. At just the right time in our history, when we all need to see the Earth from afar, we need to build this planetary consciousness, so we can become the shepherds this great planet requires.
I need to ask this question because I feel deeply biased by my upbringing. Those of us who came of age during the space race are increasingly outliers.
Through much of our time, each mission seemed to reveal marvelous new views of the home planet. Pivotal, of course, was the chance Apollo 8 photograph in 1968 that came to be known as “Earthrise”:
(Don’t miss the great narrated NASA video on the making of that photo, narrated by the Apollo historian Andrew Chaikin.)
I recently got to talk about that moment on StarTalk TV with Neil deGrasse Tyson (and his comedian sidekick Maeve Higgins).
Since then, wonders have never ceased. Consider Cassini’s views of Earth from beyond the rings of Saturn.

So, let me know what you think, and — more important — how you feel, when you get a chance to look at yourself through the eyes, heart and lens of a space-faring hero.
Postscripts  | * I forgot to include a link to the official NASA imagery portal in the initial post. On Twitter, Peter Caltner noted that the mission saw 10,880 sunrises and sunsets, not 10,994, as I originally wrote (which would have been the case if the mission had not been shortened to 340 days).

Over Half of the Data From the Pluto Flyby Is Still On the Spacecraft!!!

Over Half of the Data From the Pluto Flyby Is Still On the Spacecraft!!!


When New Horizons zipped past Pluto on July 14th, 2015,

it collected a lot of data. Couple that with the spacecraft’s agonizing,

1-2 Kbps transfer speed, and you arrive at a rather amazing fact: More than half of the data from the historic Pluto flyby is still on the spacecraft.

Sailing a probe into the cosmic void is risky business—New Horizons is

currently 3.3 billion miles from Earth and still trucking— and NASA wants to ensure it gets all of its datasets back before

something goes wrong. Over on the New Horizons blog, Emma Birath of the Southwest Research Institute in Boulder writes

about her effort to build software that ensures the data comes down to us as efficiently as possible. It’s a short read,

and well worth it if you’d like a bit more insight into the challenges behind acquiring groundbreaking scientific information over the Solar System’sworst dial-up connection.

We knew last summer that it would take New Horizons 16 months to send us all of the data it collected during its glorious flyby.

But it’s still incredible to consider that despite all the hi-res images, geologic maps, atmospheric models,

and generally amazing things we’ve learned about Pluto these past seven months, we still haven’t seen the bulk of what’s in that piano-sized probe’s memory banks.

Why Pluto is No Longer a Planet

3 Jan , 2016 by Plutofarm.

This article was originally written in 2008, but we created a cool video to go along with it yesterday

Let’s find out why Pluto is no longer considered a planet.

Pluto was first discovered in 1930 by Clyde W. Tombaugh at the Lowell Observatory in Flagstaff Arizona.

Astronomers had long predicted that there would be a ninth planet in the Solar System, which they called Planet X.

Only 22 at the time, Tombaugh was given the laborious task of comparing photographic plates. These were two images of a region of the sky, taken two weeks apart.

Any moving object, like an asteroid, comet or planet, would appear to jump from one photograph to the next.

After a year of observations, Tombaugh finally discovered an object in the right orbit, and declared that he had discovered Planet X.

Because they had discovered it, the Lowell team were allowed to name it.

They settled on Pluto, a name suggested by an 11-year old school girl in Oxford, England (no, it wasn’t named after the Disney character, but the Roman god of the underworld).

The Solar System now had 9 planets.

Astronomers weren’t sure about Pluto’s mass until the discovery of its largest Moon, Charon, in 1978.

And by knowing its mass (0.0021 Earths), they could more accurately gauge its size.

The most accurate measurement currently gives the size of Pluto at 2,400 km (1,500 miles) across.

Although this is small, Mercury is only 4,880 km (3,032 miles) across. Pluto is tiny, but it was considered larger than anything else past the orbit of Neptune.

Over the last few decades, powerful new ground and space-based observatories have completely changed previous understanding of the outer Solar System.

Instead of being the only planet in its region, like the rest of the Solar System, Pluto and its moons are now known to be just a large example of a collection of objects called the Kuiper Belt.

This region extends from the orbit of Neptune out to 55 astronomical units (55 times the distance of the Earth to the Sun).

Astronomers estimate that there are at least 70,000 icy objects, with the same composition as Pluto, that measure 100 km across or more in the Kuiper Belt. And according to the new rules, Pluto is not a planet. It’s just another Kuiper Belt object.

Here’s the problem. Astronomers had been turning up larger and larger objects in the Kuiper Belt.

2005 FY9, discovered by Caltech astronomer Mike Brown and his team is only a little smaller than Pluto. And there are several other Kuiper Belt objects in that same classification.

Astronomers realized that it was only a matter of time before an object larger than Pluto was discovered in the Kuiper Belt.

And in 2005, Mike Brown and his team dropped the bombshell.

They had discovered an object, further out than the orbit of Pluto that was probably the same size, or even larger.

Officially named 2003 UB313, the object was later designated as Eris.

Since its discovery, astronomers have determined that Eris’ size is approximately 2,600 km (1,600 miles) across. It also has approximately 25% more mass than Pluto.

With Eris being larger, made of the same ice/rock mixture, and more massive than Pluto, the concept that we have nine planets in the Solar System began to fall apart.

What is Eris, planet or Kuiper Belt Object; what is Pluto, for that matter? Astronomers decided they would make a final decision about the definition of a planet at

the XXVIth General Assembly of the International Astronomical Union, which was held from August 14 to August 25, 2006 in Prague, Czech Republic.

Astronomers from the association were given the opportunity to vote on the definition of planets.

One version of the definition would have actually boosted the number of planets to 12; Pluto was still a planet,

and so were Eris and even Ceres, which had been thought of as the largest asteroid. A different proposal kept the total at 9,

defining the planets as just the familiar ones we know without any scientific rationale, and a third would drop the number of planets down to 8,

and Pluto would be out of the planet club. But, then… what is Pluto???

This is a mystery!!!!
