Earthrise over the moon as seen by the astronauts of Apollo 8 on December 22, 1968.
Earthrise, Apollo 8

This was not the first image of the isolated Earth from space. It was the first which contrasted in the same image the wet, blue and green, atmospheric Earth with the barren, dusted, lifeless Moon.

The rising Earth is about five degrees above the lunar horizon in this telephoto view taken from the Apollo 8 spacecraft near 110 degrees east longitude. The horizon, about 570 kilometers (250 statute miles) from the spacecraft, is near the eastern limb of the Moon as viewed from the Earth. On the earth, the sunset terminator crosses Africa. The south pole is in the white area near the left end of the terminator. North and South America are under the clouds. The lunar surface probably has less pronounced color than indicated by this print.

Earthrise, Apollo 8

This iconic image has become my regular Earth Day illustration. It was not the first image of the isolated Earth from space. It was the first which contrasted in the same image the wet, blue and green, atmospheric Earth with the barren, dusted, lifeless Moon.

It is easy to deceive ourselves that we can exploit the Earth and dehumanize others – basically, sh*t where we eat and sleep – without consequences. It is hard to see, concretely and measurably, how interconnected and interdependent we are.

Images like those above remind us that we are alone, isolated, and fragile. We are stewards of the Earth. We are gardeners of the world. It’s our responsibility now.

The rising Earth is about five degrees above the lunar horizon in this telephoto view taken from the Apollo 8 spacecraft near 110 degrees east longitude.

Despite the origin of the photo at the top of this post, I am opposed to the human “exploration” of space at this stage in the development of our species and civilization. (Reporter: “What do you think of Western civilization?” Gandhi: “I think it would be a good idea.”) We know all we need which can be learned from sending and keeping humans in space, other than hot to keep humans in space. That should not be our priority. It is far too costly, in economic, human, and environmental costs, for the benefits. We have far more pressing and urgent investments to make, in education, health, and our increasing hunger for things.

Apollo: a personal/biographical perspective

40 years ago, we watched the landing on television like much of the rest of the world. Days before, my father had packed our little family into the car and drove to the causeway overlooking the Kennedy Space Center to watch, and feel, Apollo 11 send men to land on the moon for the first time. My father worked for Grumman, which had the contract to develop the Lunar Excursion Module (LEM), later dubbed simply the Lunar Module (LM), for the Apollo space program. He worked on the LEM’s telemetry systems. Part of my father is on the moon.

My family moved twice while I was growing up. Until I moved to New York City, I didn’t live anywhere longer than six years. In the winter of 1964-1965, we moved from Long Island, east of new York City, to Merritt Island, Florida. As you can see from this map, our home was just a little over 10 miles from the Apollo 11 launchpad. I used to watch rockets launch from my bedroom window. On most launches, our windows shook.

The Apollo program had an enormous economic and human toll, an important part of the story which I’ve yet to read anywhere else. Shortly after we moved to Florida, my father began working 60-80 hours a week, a pace which didn’t let up until nearly the end of the development program. Once it became routine to send men to the moon, the development program ended abruptly. Hundreds of thousands lost their jobs simultaneously in a region whose development was triggered by this one program. My dad was able to find another job within Grumman, but it required moving back to Long Island. With no buyers, we were only able to sell our home at a greatly reduced price, losing all our equity, and having nothing with which to buy a new home.

We moved back to Long Island in the fall of 1970, just in time for me to start the school year, though just one week late.

Earthrise, Apollo VIII, December 22, 1968
Earthrise, Apollo 8

I remember when we first received images of the earth from space. This image, taken by Apollo VIII astronauts returning to Earth after circumnavigating the moon, was not the first. But, showing the green, wet, full-of-life, and finite Earth in stark contrast to the dry, lifeless Moon, it helped energize the environmental movement.

The rising Earth is about five degrees above the lunar horizon in this telephoto view taken from the Apollo 8 spacecraft near 110 degrees east longitude. The horizon, about 570 kilometers (250 statute miles) from the spacecraft, is near the eastern limb of the Moon as viewed from the Earth. On the earth, the sunset terminator crosses Africa. The south pole is in the white area near the left end of the terminator. North and South America are under the clouds. The lunar surface probably has less pronounced color than indicated by this print.

Here in Brooklyn, at the end of last week and into the weekend, we got drenched with a couple days of rain. Fellow gardeners in Massachusetts, Vermont, New Hampshire, and Maine, I sympathize.

New England Ice Storm, 2008.12.13

In this image, snow is red and orange, while liquid water is black. By the time this image was taken [On December 13], the top layer of ice was undoubtedly starting to melt, and the resulting watery ice ranges from dark red to black. The icy region extends over parts of Massachusetts, Vermont, and New Hampshire … The normally green-blue tone of plant-covered land is nearly black throughout most of New Hampshire, the state most severely affected by the storm.

Fall Approaches, 2008

I’ve been watching fall advance locally: first the red of the Dogwoods, the yellow of the Locusts, the psychedelia of the White Ash. When my system gets back up and running, I’ll have some photos of my own to share. Meanwhile, NASA treats us with their annual satellite perspective on the phenomenon. This is how it looked about two weeks ago.

Fall Color in the US Northeast

Fall was beginning to color the East Coast of the United States when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image on October 12, 2008. Orange touches trees in the north and at higher elevations, where temperatures are cooler. Lower elevations are still green. The fall color follows the sweep of the Appalachian Mountains through Pennsylvania, New York, and into New England.

The image also illustrates the dense population of the East Coast. Cities are gray in this photo-like image. The greater New York City region covers a large area on the coast. Boston, Massachusetts, and Providence, Rhode Island are also clearly visible.

Satellite Image of Northeast’s First Snow of the Season

Satellie view of the first snow in the Northeastern United States

A string of storms brought the season’s first snow to the eastern United States from the mid-Atlantic states to New England during the first week of December 2007. By December 6, most of the clouds had cleared, providing the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite this view of the snow-covered landscape. The snow highlights the contours of the land. Waves and curves follow the gentle folds of the Appalachian Mountains through Virginia, West Virginia, Maryland, and Pennsylvania. The more rugged mountains of New Hampshire, Vermont, and New York wrinkle the surface of the land.

The snow also makes rivers and lakes more visible than they might otherwise be. The dark blue-green Finger Lakes of upstate New York pop out against the surrounding white land. The long narrow lakes formed when glaciers scoured, deepened, and eventually dammed stream valleys. The lakes point north and northwest to the shores of Lake Ontario, portions of which are visible beneath a bank of clouds in this image. The northern shore of Lake Erie similarly peaks through the clouds to the west. In the far north, particularly in Maine and Canada, lakes have already started to freeze. The ice is a smooth, bright white surface in contrast to the slightly darker land.

To the south, snow-covered Maryland surrounds the northern Chesapeake Bay, starkly outlining the ragged shoreline where rivers and streams enter the bay. The largest river flowing into the Chesapeake is the Susquehanna, which cuts southeast across the Appalachian Mountains of Pennsylvania.

Here’s a closer view of the NYC area.

Images: Fires in Southern California

Update 2007.10.24: NASA continues to publish updated satellite imagery of the fires and the natural phenomena driving them. Check the sidebar of their page for “Other Images for this Event”.

By Wednesday morning, 600,000 people had been displaced by the fires. By the afternoon, CNN upped the estimate to over 900,000.

Image acquired 2007.10.22 13:55 PDT

Watching the news this morning before going to work, I was shocked to hear that a quarter of a million people – 250,000 – have been displaced by the fires in California. This satellite image, taken less than 24 hours ago, provides some sense of the scale of what’s going on there.

In what seemed like the blink of an eye, wildfires ignited in the paper-dry, drought-stricken vegetation of Southern California over the weekend of October 20, 2007, and exploded into massive infernos that forced hundreds of thousands of people to evacuate their communities. Driven by Santa Ana winds, fires grew thousands of acres in just one to two days. The fires sped down from the mountains into the outskirts of coastal cities, including San Diego. Dozens of homes have burned to the ground, and at least one person has died, according to local news reports. Several of the fires were burning completely out of control as of October 22.
…
The drought in the Southwest throughout summer 2007 has been “extreme” according to the categories used by the U.S. Drought Monitor. Dry vegetation and Santa Ana winds, which can reach hurricane force as they race downslope from the deserts of the Great Basin and through narrow mountain passes, are often a devastating combination in Southern California. According to the Incident Management Situation Report [PDF] from the National Interagency Fire Center for October 22, Santa Ana winds were expected to continue through Wednesday.

NASA images by Reto Stöckli, based on data.
The Earth, Side B

Spectacular composite images from NASA. If you have the bandwidth, definitely check out the full size renditions (Eastern hemisphere, and my home, the Western hemisphere), each of which is nearly 3MB in size. You’ll feel like you’re floating in space over the earth.

These are not photographs. These are carefully constructed from large databases of images taken at many different times and places.

Drawing on data from multiple satellite missions (not all collected at the same time), a team of NASA scientists and graphic artists created layers of global data for everything from the land surface, to polar sea ice, to the light reflected by the chlorophyll in the billions of microscopic plants that grow in the ocean. They wrapped these layers around a globe, set it against a black background, and simulated the hazy edge of the Earth’s atmosphere (the limb) that appears in astronaut photography of the Earth.
…
Most of the data layers in this visualization are available as monthly composites as part of NASA’s Blue Marble Next Generation image collection. The images in the collection appear in cylindrical projection (rectangular maps), and they are available at 500-meter resolution. The large images provided above are the full-size versions of these globes. In their hope that these images will inspire people to appreciate the beauty of our home planet and to learn about the Earth system, the developers of these images encourage readers to re-use and re-publish the images freely.
