One of the largest icebergs on the planet, about six times the size of Manhattan, has separated from an Antarctic glacier and is floating out towards open ocean. The iceberg is named B-31, and is roughly 255 square miles (660 square km). Its estimated maximum thickness is 1,600 feet (487 meters). Last Fall, it broke off from the Pine Island Glacier. Researchers have been watching it drift away since then, via satellite.
"The ice island, named B31, will likely be swept up soon in the swift currents of the Southern Ocean, though it will be hard to track visually for the next six months as Antarctica heads into winter darkness," according to scientists at NASA's Earth Observatory monitoring its progress.
Speaks for itself, doesn't it? NASA:
When the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this image on December 7, 2013, thick haze stretched from Beijing to Shanghai, a distance of about 1,200 kilometers (750 miles). For comparison, that is about the distance between Boston, Massachusetts, and Raleigh, North Carolina. The brightest areas are clouds or fog. Polluted air appears gray. While northeastern China often faces outbreaks of extreme smog, it is less common for pollution to spread so far south.
If a Saturn V rocket had ever exploded on the launchpad, it would have been a catastrophic event. NASA engineers once calculated that the resulting fireball would have been 1048 feet wide and would have hit temperatures as high as 2,500 degrees Fahrenheit. In the hopes of not losing astronauts or launch crew to the inferno, NASA tricked out the Apollo launchpad with some safety systems that still exist today, including an underground, rubber-lined bunker that was accessible from the launch platform via a 200-foot twisty slide. (Which almost sounds like fun, until you consider the context.)
Amy Shira Teitel is one of the few people who have been inside the rubber room recently. In the video above, and she shares photos and stories about it in the video above, at her blog, and on Discovery.com.
Here's something new for the BoingBoing evil lair collection — NASA is selling the massive platforms that used to move spacecraft from the hangar to the launchpad at Kennedy Space Center. From The Guardian:
The platforms provided power and umbilical connections to Apollo and the shuttles, and had open sections for flames and rocket exhaust to pass through. "At this point Nasa is looking to gauge interest for potential use of the [platforms] and concepts for potential use," spokeswoman Tracy Young said. Proposals are due by 6 September.
I'm sure you all have some good ideas.
EDIT: I previously understood this story to mean that the whole platform/crawler system was for sale. That appears to be incorrect. You can't have the tread-wheeled vehicle. NASA will be using that. But you can buy the platform that sat on top of the vehicle.

This photo, taken by astronautics grad student and photographer Ved Chirayath, was meant to be a bit of free promotion for NASA and space exploration. It's part of an art exhibition called Physics in Vogue, which combines real science with the style of fashion photography. With the help of a Viking re-enactment troupe and some of his colleagues from the Ames Research Center, he put together a shot that was meant to connect current NASA projects to the exploration-oriented Viking culture. What if two of Earth's greatest explorers met face-to-face?
The photo was done on Chirayath's own time, using funds from two arts grants that had nothing to do with NASA. But it has become the center of an extensive investigation initiated by Senator Chuck Grassley, aimed at discovering whether dastardly NASA scientists were using taxpayer money to make whimsical photos. They weren't. Ironically, though, the investigation did use taxpayer money. More, Chirayath estimates, than it would have cost him to get such a photo done by a professional.
On Sunday, NASA launched three PhoneSats into orbit. House in a standard "cubesat" structures, a Google-HTC Nexus One serves as the onboard computer and sensor system, taking photos of Earth. Aamateur radio operators are monitoring the transmissions and picking up data packets that will be recombined here on Earth. According to a NASA press release, the use of commercial-of-the-shelf parts, a minimalist design, and limited mission requirements kept the cost of each satellite as low as $3500.
