In 1998, Vice President Al Gore had a vision for "Triana," an imaging satellite that would continuously transmit a live "big blue marble" Earthview for the nascent World Wide Web. Designed, built, and scheduled for launch in 2001, the $150 million "GoreSat" became a victim of politics during the W. Bush administration, and was relegated to a closet at the Goddard Space Flight Center. Friendlier heads revived the satellite in 2009 as the NOAA's DISCOVR - the Deep Space Climate Observatory - and launched her on a SpaceX Falcon 9 rocket last year. Today, NASA published her first "epic" view of Earth.
Japan’s new geostationary satellite Himawari-8 captures an image of Earth every 10 minutes. The New York Times combined some of them into a spectacular view of a single day over the Pacific Ocean.

Political geographer Phil Steinberg reacts to marine ecologist Jon Copley's piece on the new gravity model of the ocean floor from David Sandwell and others at the Scripps Institute of Oceanography. "Instead of understanding the ocean as something to see through as one seeks to map the seabed, water is reframed as something to see with. Volume, rather than being understood as a barrier to vision, becomes a means for achieving that vision." Copley asks: "Philosophically, when it comes to exploring anywhere on our dynamic world, how and when do we decide that somewhere has 'been explored'?" (via)

On July 18th, Russian researchers launched a Foton-M satellite in hopes of study how reptiles reproduce in a zero-g environment. They lost the ability to send commands to the biosatellite later that same day.
The Corona Atlas of the Middle East uses spy satellite imagery to reveal as many as 10,000 previously unknown archaeological sites.
Revision Demoparty was held this past Easter weekend. It's considered to be a rebirth and spirital heir of the Breakpoint Demoparty, and, arguably the flagship "Demoscene" event of the year. A lot of groups and individuals bring their A game to show off the most inspiring, technically-intense and memorable demos to the world. Every year has highlights and it's a big deal when a brand new platform gets a demo, but this year, the wildest demo went in an entirely unexpected direction: space. [more inside]
When can I spot the Space Station? The International Space Station can easily be spotted with the naked eye. Because of its size (110m x 100m x 30m) it reflects very much sunlight. This simple tool will tell you all of the opportunities you can view the ISS over the next ten days, along with a brightness index and a map tracing its transit across your local sky. The red line shows where the ISS is sunlit and visible. On the blue line the ISS is in the Earth's shadow and invisible or it is less than 10° above the horizon. [more inside]
The 14th moon of the planet Neptune has been confirmed. New Scientist: "...its existence is an enigma. The object, known for now as S/2004 N1, is the first Neptunian moon to be found in a decade. Its diminutive size raises questions as to how it survived the chaos thought to have created the giant planet's other moons." [more inside]
The Long Swath is a satellite image by NASA's Landsat Data Continuity Mission that captures, in a single continuous image, a strip of land 120 by 6,000 miles stretching from South Africa to Russia. The image can be explored in Gigapan, Google Earth, and fly-over videos and high resolution images.

The United States Department of Defense has generously "decided to give NASA two telescopes as big as, and even more powerful than, the Hubble Space Telescope." They apparently had some antiquated spy satellite hardware sitting around unused and unwanted. NASA still needs to find money to outfit them with recording instruments and pay a team to manage them, which may take 8 years

GPX riding is a general term for using a GPS device to track and record location while riding a bicycle [previously on MetaFilter]. Combining this technology with a planned effort to create art is the premise behind Wallygpx. Think of the images as being akin to a giant etch-a-sketch.
Some time late tonight or early tomorrow morning, NASA's UARS (a satellite deployed in 1991 to study the ozone layer) will fall to the Earth. The odds of it hitting you are about 1 in 20 trillion, but the odds of it hitting somebody somewhere is about 1 in 3,200. The Planetary Society Blog has a nice writeup as well. Follow along yourself with NASA or the Center for Orbital Reentry Debris Studies. [more inside]

We tend to think of blogs that showcase large images as a phenomenon of the past few years. But NASA's Earth Observatory has been posting its Image of the Day since April 1999 (when its first "large" image available for download was a 214 KB jpeg of the North Pole). Now, Image of the Day has downloads of images in multiple formats, most of which measure in megabytes, not kilobytes, and these stunning images of the earth's surface give context to the human activity down below: a toxic spill in Hungary, wildfires in Mexico, the growth of a coal mine in West Virginia, agriculture in Brazil, snowmelt flooding in Fargo, North Dakota, last year's oil spill in the Gulf of Mexico, artificial islands in Dubai, the aftermath of Japan's recent tsunami.
The GOCE satellite has completed its survey of the Earth's gravitational field.

Baghdad nights: evaluating the US military ‘surge’ using nighttime light signatures (PDF). A team of UCLA geographers using satellite imagery to track the amount of light emitted in Baghdad at night found that electricity use in Sunni neighborhoods fell prior to the surge and never returned, indicating that ethnic cleansing by Shiite militias drove the Sunnis away before the surge began and was largely responsible for the subsequent decrease in violence.
