The GeoEye satellite continues its stunning photo series

Here are a couple more from our favorite eye in the sky.
Both half-meter resolution images were snapped from space by the GeoEye-1 satellite, which also took those fantastic pics of the National Mall on Inauguration Day.
As promised, here are stunningly clear satellite images of the tops of some two million heads during today’s inauguration. These images were snapped at 11:19am today by GeoEye-1, the most powerful commercial imaging satellite in the sky, from 423 miles above the trampled grass on the National Mall.
On December 6, 1957, hot on the heels of Sputnik, the United States Navy readied the first American satellite, Vanguard, for launch. The grapefruit-sized device lofted 3 feet from Earth before it exploded. Press and public jeered, dubbing it "Flopnik." ("The exact cause is classified," says the crisp narrator in a vintage video [below] of the attempt.) A red-faced U.S. government redoubled their efforts. Within a year and a half, Vanguard's replacement took the first measurements of Earth's upper atmosphere and its successor, Vanguard II, the first scan of Earth's clouds.
Though we may often think of cholera as a disease of the past, virtually eradicated when John Snow famously linked an 1854 outbreak of the epidemic in London to an infected water well on Broad Street, it still poses a threat in almost every single developing country in the world. Over 150 years after Snow essentially founded modern epidemiology, a team of American scientists are using remote satellite imaging to predict cholera outbreaks before they occur.

The sands of Harrat Khaybar, in the Saudi Arabian desert, weren't always so parched. Evidence on the ground, such as fossilized hippo teeth, has led geologists to conclude that this dessicated lava field was once a lush grassland. But the case is even clearer from space, as seen in this photograph, taken from the International Space Station in March.
A growing cloud of trash threatens space tourism and has experts scrambling to clear the mess

Along with satellites and space stations, Earth is surrounded by tens of millions of pieces of floating space debris. Like any landfill, the trash is diverse, ranging from dead satellites to castaway rocket parts to flecks of paint. On average, over the past 40 years, one piece of space junk has fallen to Earth every day.
Asteroid 2008HJ is the fastest-rotating natural object in our solar system

Asteroid 2008HJ is not only a "superfast rotator," it's the fastest of the superfast. According to the British amateur astronomer Richard Miles, who clocked the asteroid using the remotely operated Faulkes Telescope South, 2008HJ makes a full rotation every 42.67 seconds—almost twice as fast as the previous record holder.

In the first ever instance of a spacecraft photographing the landing of another craft on Mars, the Mars Reconnaissance Orbiter captured this incredible image of NASA's Phoenix Lander making its descent on Sunday. Phoenix landed successfully and has already begun transmitting images from its landing zone in Mars's northern polar region, where it will be conducting meteorological and geological surveys over the course of its three-month mission.
What does the past look like from 200 miles up? A new generation of archaeologists has found that the history of civilization may look far clearer from the top of the atmosphere than it does from the bottom of a dig

If it weren’t for the landmines, Lingapura would be a great place to dig. For part of the 10th century, this pocket of northwestern Cambodia was the capital of the famed Angkorian empire, a sprawling city studded with homes, irrigation channels, and more than 1,000 temples crowned with stone lingam, or phalluses. But ever since Pol Pot and the Khmer Rouge dotted Cambodia with millions of landmines in the 1970s, Lingapura’s ruins have sat mostly untouched.
